My invention consists of an, apparatus for receiving cash for gas supply either in
small or large quantities, the object being to enable gas companies to supply gas by
prepayment at low prices, & so put gas supply upon an equal basis for competition
with oil lamps.
I construct my receiving apparatus so that by putting a penny or coin or coins
through an aperture provided for this purpose in combination with a gas meter,
when the coin or coins are put into the aperture the meter commences & continues
to work until the quantity of gas to be supplied in value for the coin or coins is
delivered for freeing the meter by a coin or equivalent, I use a disk which is geared
to the meter, and worked by the meter, upon which is a moveable periphery held to
the disk by friction, and which said periphery can be moved upon the disk by
separate gear (independant of the motion of the disk by the action of the meter as
before described) by the action of a coin or equivalent being placed in the receptacle,
upon the outside edge of the périphery a groove is made for two purposes, first when
the lever which is actuated by a coin. rests in this groove, the meter is at rest, the
action of putting a coin in the receptacle lifts this lever out of this groove, and by
the same motion advances the moveable periphery round the disk a certain distance
and at the same time liberates the meter which is impelled by the pressure of the
gas until it returns to the same position as at first, when the lever falls into the
groove as at first during the time of this action the quantity of the gas passed
through the meter is the value agreed for the coin, without waiting for the meter to
stop by the above action any further number of coins may be placed in the coin
receptacle to be paid out in value in gas until the moveable periphery has nearly
completed a circle round the disk, second use of the groove in the moveable peri-
phery, when it has nearly completed a revolution the groove comes under the action
of another lever which falls into it by a decline, this lever is pivoted near the
centre and the other end operates upon a shutter which closes the apperture from the
reception of any further coins until the moveable periphery with the groove, is again
retired by the action of the meter in doing so it lifts the lever again and the apperture
for the reception of coin, each operation of putting in a coin will be shown upon a

page_text: :
dial, worked by gear from the moveable periphery, which will show at a glance how
much cash has been deposited in the receptacle for which gas is still to be
supplied.
.
The methods of stopping the meter by the lever when it falls into the groove as
before described, may be either closing the inlet or the outlet passages of the gas
through the meter by valves actuated by this lever, or by arresting the advance of
the meter for the latter method I propose to work another disk side by side by the
before described disk with the moveable periphery and worked from the meter by
gear at a speed slower than the meter, also with a groove upon its periphery, so that
the same lever may drop into it this lever being made wide enough for both disks,
but the lever cannot drop into this second disk, until releived by the first named disk
with the moveable periphery, this last mentioned disk, may also have a frictional
peeiphery or attached with a spring so as to take off any shock when the lever falls
into the grove and suddenly stops the meter. For receiving the coin I use a lever
At one end of this lever
pivoted at a point between the two ends to a ratchet wheel.
is the balance weight, at the other end the rescepticle box for the coin; when a coin
is dropped into the rescepticle box the lever at once falls and carries with it the
ratchet wheel by a fall; upon the same shaft upon which the ratchet wheel is fixed, is
fixed a spur wheel to gear into the moveable periphery of the first named disk to
give motion to it. A wheel is also fixed upon the centre of the lever to gear into
the wheel upon the stop lever shaft to actuate the stop lever.
My method of releasing the coin from the rescepticle box.
Г
On the end of the lever the bottom of the rescepticle box is closed by a ballanced
.bottom in the form of a lever, one end of which forms the bottom of the rescepticle
box, and the other end of this lever when it falls to the bottom catches a projected
balanced lever fixed to the outside case. When the coin is put into the rescepticle
box, the lever falls, the bottom of coin, box is opened by the projecting balanced
lever fixed to the outside case, and the coin falls into the cash box below; the main
lever then returns, the balanced projecting lever lifts up to allow the coin box lever
to pass, the ordinary index upon the gas meter giving the quantity of gas consumed
and so check the amount of cash deposited for gas.

An Improved Gas Meter for Supplying Gas in Exchange for Com
or an Equivalent.
I, ROWLAND WILLIAM BROWNHILL, of 17, Temple Street, Birmingham, in the
County of Warwick, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to an automatic sale, and delivery gas meter, or a gas
meter provided with mechanism or apparatus, for giving out a determinate quantity
of gas, on the same having being previously paid for, by depositing a coin or coins
within a receptacle, or through a slit made in the enclosing framing of the said
automatic means.
Thus the automatic sale and delivery means, in connection with a gas meter
consists essentially of a counterpoised lever, which is controlled by a coin or coins,
introduced as prepayment, for an amount of gas to be supplied; and which lever,
through links or the like, gives a proportionate or partial backward movement to a
disc or dises, having inclined notches cut within their peripheries, within which a
'catch or cross bar lies, when the meter is at rest.

page_text: The other parts consist essentially of trains of wheel-work, which are driven
directly from the drum of the meter, and through some of them, communicate the
necessary backward movements to the discs, which are the gas measuring out means.
These discs are coupled for their backward movements, by suitable devices, as herein-
after described.
Figure 1 represents in front elevation, a portion of a gas meter, provided with
automatic sale and gas delivery mechanism, constructed and arranged according to
one part of my said invention.
Figure 2 represents partly in elevation, and partly in vertical section, the said
mechanism, meter and auxiliary parts, in connection with them, by. which means, a
predetermined quantity of gas is measured out, and allowed to flow through the meter,
after a coin which is the equivalent in payment therefor, has been dropped through
a slit, and from thence passed into a balanced receptacle placed thereunder, to
receive it. The said mechanism Figure 2 is shown in the position which it assumes,
when it is in its normal position, or in a position of non-supplying. It will be
seen also, that the catch or stop is resting within the slanting notch, made within the
periphery of a measuring out penny disc; that is, a disc which indicates twelve
pennyworths of gas, if it makes one rotation.
Figure 3 represents a like view as Figure 2, but with the parts of the mechanism
in the positions which they assume after a coin has been dropped into the receptacle
made to receive it, in prepayment of a predetermined quantity of gas as aforesaid.
The coin thus deposited, is shown dropping through the now open bottom of the
movable coin box (in dotted lines) after it has done duty, in giving a proportionate
or partial-rotation to the measuring out discs, and releasing the going wheels, and
drum. of the meter.
Figure 4 is a top side plan, and part horizontal section of the said mechanism
Figures 2 and 3, thus showing more clearly the positions of the gas measuring out
discs, and other parts, with respect to the trains of wheels, which communicate
motion to the indicating finger axes.
-
Figure 5 represents partly in transverse vertical section, and partly in end
elevation, the said mechanism and auxiliary, and attendant parts. This view shows
clearly the drum axis of the meter, from whence the motion for the taking of the
parts of the mechanism back to their normal positions as hereinafter described, is
derived.
Figure 6.represents the combined ratchet wheel, and penny measuring out disc
or wheel, and with a counterpoise pinion axis, bracket and intermediate wheel, which
latter gears with the teeth of a toothed annulus, carried by, and made in one piece
with a toothed wheel, whose only motion is received from the main axis, which is
driven from intermediate wheels, between the druin axis. This combined annulus
and toothed wheel, is represented at Figure 7, and with a counterpoised pinion in a
position which it assumes, after the measuring out disc, upon whose face it is carried,
has passed through a distance of one twelfth of a revolution, and an equivalent to a
distance equal to one penny-worth of gas..
'
Figure 8 represents front elevations of the penny-measuring out disc, and the
shilling measuring out disc, shown one before the other. The front top part of the
former, is broken away to exhibit the slanting notch, in the latter. This view also
shows the relative positions of the notches, with respect to each other, after a coin
has been deposited, for the prepayment of a certain quantity of gas.
The same letters of reference indicate corresponding parts in Figures 1 to 8.
a is a gas meter, provided with the usual delivery, or service pipe, and the gas
passing therethrough, is controlled by the drum of the meter, which is driven by the
flow of gas, whose volume it measures. The chambers in the drum are of known
capacity, and the revolutions are conveyed to a distance by trains of wheel-work, and
then registered upon dials.
b is a counterbalanced lever, moved by the weight of a descending coin, placed
within a receiving box 62, placed at one end of the said lever, which is fulcrumed
at 63, near the other end, thus making a lever with arms of unequal lengths with the

page_text: coin box at the end of the longer arm, and a swinging counterpoised weight 64 at
the end of the shorter arm.
The mouth of the coin box 2, is hopper shaped, and comes under and opposite the
lower open end of a depending guide ³, leading from a guide-slit a², situated at the
upper part of the enclosing casing at, of the automatic sale and delivery mechanisin
of the meter as best seen in Figures 2 and 3.
The coin box 62 has an open and balanced bottom b5, consisting of a jointed and
counterpoised short arın, fulcrumed at 60, to a bracket extension of the lever; and
which said arm extends a short distance under the said open bottom. The other
end is heavier than the combined weights of both coin and short arm; so that if
a coin be dropped through the slit into the coin box, the long arm, and coin box at
its end, descends and brings the counterpoised, or weighted end b, of the balanced
bottom, suddenly against a fixed coin liberator 68, secured to the inside of the enclos-
ing casing.
The momentum thus acquired, by the falling boss end of the lever, raises the
weighted end 67, and turns outwardly the bottom, thereby liberating the coin c, which
being no longer supported, falls by gravity through the open bottom of the box,
into a receptacle or drawer, placed thereunder, to receive it, as represented in
Figure 3.
While the coin box end of the lever descends, the other, and short arm, rises, and
as its fulcrum pin turns with the lever, a rising motion is given to the connecting
rod d, and the jointed arm e, whose other end is connected to the upper end of the
said rol, and with its other extreme end es jointed to the framing. The connecting
rod at its lower end is connected to the short arm d³.
ז'
The arm has a swinging hooked ended pawl f, with a flat spring at its back, for
taking it up to the teeth of the ratchet wheel g, which is disposed upon the face of
a gas measuring out penny disc h, whose periphery has a notch or gap h², wherein the
catch e, carried by the arm e², drops or lies, when the machine is at rest.
The ratchet wheel g, and measuring out disc h, are fast upon an arbor, whose
outer end is reduced, and carries a finger, which indicates before a dialj Figure 1,
the number of pennies up to 12, which have been deposited into the receiving or cash.
box of the apparatus; thus, if one penny be passed through the slit, and the
apparatus worked, then the finger, will have traversed one twelfth the dial
field.
The arbor i is extended rearwards, from the back of the penny measuring out disc,
and working and taking its bearing in the middle of a ratchet wheel l, which is made
fast with a spur wheel m, which is driven from the drum axis m², through intermediate
wheels and pinions m³ m.
Made fast upon the extended end of the arbor i, is a pinion n, through which
motion is communicated to the shilling measuring out disc o, and shilling finger 2,
which is carried by the neck of a toothed wheel p, driven by a pinion p³ of a
spindle p*, fast with a toothed wheel p³, which gears with the pinion n as
-aforesaid.
The shilling mensuring out disc has a spur wheel o² fast upon its back face, which
is driven by a pinion p", on the axis p; and further, the shilling measuring out dise o
has a notch o, like a notch h² in the periphery of the disc h, wherein the catch e lies,
on its notch and the one cut within the periphery of the penny disc, becoming
coincident.
The shilling disc o, and the spur wheel 2 at its back, is loose upon the extended
arbor and disposed between the pinion n, and the back of the disc h.
The catch e, when it lies within the notches h², 03, it then necessarily lies also
within the teeth of the ratchet wheel l, and thereby fixes the drum of the meter in a
non delivering position, as will be hereinafter more fully described.
Working loosely upon the arbor i, is a toothed wheel q, having formed within its
inside face, a toothed annulus q, upon the face of which, a pinion g2, through
the intervention of an intermediate wheel g³, carried by a bracket g', rolls. This

page_text: pinion has fast upon its axis, a counterpoise weight g, turning upon a pivot g³,
working within a bearing, made within the face of the ratchet wheel g.
The bracket g is also carried by the ratchet wheel; so that on the ratchet
wheel being moved forward, by the rising of the pawl f, through the descending
movement made by the long arm of the lever, the intermediate pinion g³, is
made to roll upon the face of the toothed annulus q², to an extent equal to the
amount of gas which is to be allowed to be given out through the meter, in lieu
of the coin or coins deposited.
.
The pinion g2 which is fast with the weight g³, forms a clutch for making fast the
wheels q, q, with the ratchet wheel g, disc h, arbor i, *, and pinion n, and shilling
disc, toothed wheel at its back, and other intermediate wheels and pinions, working
in connection with the shilling finger ?>.
Thus, the upward movement of the connecting rod d, imparts motion to the ratchet
wheel g, to the extent of six teeth, and raises the cross catch e, from the notches h², o²,
and teeth of ratchet wheel b, while the backward movement of the ratchet wheel g,
makes the pinion g², roll upon the edge of its intermediate pinion g³, which in its turn
rolls upon the teeth of the toothed annulus q², which remains quiescent, as it is in
direct communication with the meter wheel m, through the pinion 12, wheel 13,
pinion, wheel, pinion ", wheel 17, and smaller toothed wheels, which latter gears
with the spur wheel 9.
Thus, as the ratchet wheel moves forward, to the extent of six teeth as aforesaid,
the pinion, intermediate wheel, bracket and counterpoised weight move round with
it, and if a penny be the sum deposited, then the said ratchet wheel and parts carried
by it, will move round to the extent of one twelfth of a revolution of the penny disc,
which will be indicated upon the dial, by the finger, moving at the same time, as
it is on the axis of the parts as aforesaid.
The counterpoise weight g of the pinion g², rolls over with the pinion g², and
perforing a tumbler like action, and whose function is to take the pinion upon the
annulus, to the extent. of one complete rotation, which might not take place, as slight
differences in the movement of the ratchet wheel, might be imparted, by the motion
of its hook ended pawl.
The face wheel has pivoted upon its face, a lazy weight g', which is passive in its
action, but counterpoises the action of the weight 95.
It will be observed that the wheel p², carrying the shilling finger p, traverses the
dial, for a penny, to the extent of one 144th of a revolution; and which said wheel p²
is speeded down by the reduction wheels p³, p³, p³.
.
The action of the apparatus is as follows:
On a penny being placed through a slit a², in a framing enclosing the automatic
sale and gas delivery mechanism, it passes down the mouth of the guide a³, and is
deposited in the coin receiving box 62, which now becomes heavier than the parts
carried, and in connection with the short end of the lever b; so that the coin box
descends into a position as represented in Figure 3, with the weighted end 67, of the
balanced bottom 65, of the said box, striking itself against the coin liberator 68, which
causes the said balanced botton to open outwardly, and liberate the coin, which being
no longer supported, falls by its own weight, into a box below, for to receive it.
The downward movement of the coin box 62, presses upwards the connecting
rod d, and raises the arın e² so as to take the catch e, from out of the inclined
notch h², of the penny measuring out disc h, notch o³ of shilling measuring out
disc o, and from the teeth of the ratchet wheel 1, while the upward movement of
the swinging pawl f, after the catch has been raised out of the notches, and from
between the teeth as aforesaid, (which thus liberates the meter, and leaves free the
discs) gives a proportionate or partial-forward rotation to the ratchet wheel g, and
disc h, to an extent of one twelfth of a revolution, and gives the shilling disc o,
a proportionate or partial-rotation to the extent of 144th of a revolution, which
diminution of speed is acquired, by being driven from the pinion n, on the same
arbor, as carries the penny disc, and ratchet wheel. This one twelfth movement of
the arbor i, gives to the finger ³, a like movement in front of the dial, while the

page_text: finger p, is made to take only 144th movement of the said finger 23; and further,
the said backward movement of the ratchet wheel g, carries with it the pinion g², g³,
bracket, weights 95, 7, and makes the intermediate pinion g³, roll upon the
toothed face of the annulus, to an extent equal to the ratchet wheel; and on, it
making one complete rotation, as represented in Figure 3, after the manner of a
sun and planet movement, the wheel and annulus q², which are loose upon the
arbor i, are now locked with the ratchet wheel, and, parts, moving with it; and as
the annulus and toothed wheel 9, 92, are driven by the meter drum, it necessarily
follows, that instantly the said toothed wheels and parts carried by it. become locked,
then a counter movement equivalent to the meter drum noveinent, takes place, and
carries the penny measuring out disc, and ratchet wheel back, until it comes
opposite the underside of the catch e; and as the motion of the shilling disc, is
governed by the motion of the penny disc, then, after a pennyworth of gas has been
consumed, the two discs turn back to their former positions, with the notches ², 03,
becoming coincident, which then allows the catch or tooth e, which has subse-
quently been pressing upon their peripheries, to fall and lie within the said notches,
and, between two of the teeth of the ratchet wheel 1, thus stopping the meter, and
allowing the coin box 62, to rise to a further extent equal to the depth of the notches
as aforesaid.
4.
It will be further observed, that after the coin has descended, and allowed the coin
from it to fall, it then returns, not quite to its former position, as the catch e rests
upon the peripheries of the discs & and,o.
When more than one coin is placed within the coin box, it is necessary that the
same should rise before a second one is placed therein; and when, say, a dozen coins.
have been deposited, the tumbling weight, and its pinion 92, 95, makes twelve
tumbling revolutions, which brings the notch of the penny wheel at the top, and in a
position from whence it started, but as the shilling disc has been advanced to an
extent equal to one twelfth of a revolution, the notches are of different positions, so
that the catch rests upon the periphery of the shilling disc, and until these notches
become coincident, the meter will deliver gas, equal to a back rotation of the penny
disc, and a twelfth back rotation of the shilling dises; so that it will be seen that 143
coins can be intermittently deposited, without the notches in the discs becoming
coincident, and gas given out to the value of 143 pence.
Figure 9 represents my said invention provided with a valve, for cutting off, and
adınitting of the flow of gas, instead of by stopping the drum of the meter, as in,
the previously described arrangement. The whole of the mechanism parts with the
exception of the ratchet wheel are the same.
Thus a is the meter, is the guide of the slit, and at the enclosing casing of the
automatic sale and delivery mechanism. b is the counterpoised lever 62 is the
coin box, b is the, bracket at its end, ³ the centre of the lever (the swinging
counter-poised weight is not shown) 65 is the balanced, bottom of the coin box,
6 is the fulcrum pin, and 67 a weighted end, and 8 an upwardly directed coin
liberator, which as aforesaid, strikes the underside of the weighted end 67, on the
descent of the coin box. d is the connecting rod, connecting-the-armel, with a
lever b, and which arm is fulcrumed at e³. e is the catch or tooth shown upon the
peripheries, of both measuring out discs h and o. g is the ratchet wheel upon the face
of the disc h, with the teeth thereof, the hooked end of the pawl f. engages,
and which pawl is pressed home by a spring arranged at its back for that
purpose.
The discs hand o have notches within their peripheries, whilst motion is
communicated to the fingers i³, p, which traverse the dial field at their
backs.
Motion is communicated to the mechanism from the drum of the meter, by spur
wheels or pinions r, 12, which former is fast upon an axis with a pinion at its end,
which gears with a toothed wheel m, and from thence to the trains of wheels of the
mechanism as aforesaid. The shaft of the wheel 72 extends vertically downwards
within a sleeve, and is driven and connected with the drum of the meter.

page_text: In the said Figure 9, of which Figure 10 is a longitudinal vertical section, the
mechanism, and the enclosing casing, with dial upon its front, is shown in elevation,
but the water slide which prevents the escape of gas from the service leading from
the meter, is shown in complete section.
8 is a water slide, consisting of an outer tube &, open at top, and closed at bottom,
by the said bottom end screwing within a socket 2, made upon the top of the valve
casing t.
u is the outlet from the meter, and is the service pipe, wherethrough gas is
allowed freely to pass by the opening of a valve w, carried by a stalk w², worked by
a jointed arm, jointed at 2, and whose free end rests upon the outer end of the
arm e
The stalk w² of the valve, carries an inner enclosing tube w³, and works up and
down within water placed within the interior of the outer casing 82, wherein water or
of gas through
mercury is placed, so as to form the seal, in preventing the escape
the gland, of which the inner tube directly surrounds the valve stalk.
The lower extension of the valve stem is guided within a socket 3, of which the
dish shaped top t forms the valve seat.
Thus on the placing of a coin through the slit a², the coin-box b descends, and
raises the connecting rod, which lifts the arm e², and the valve stalk arm upon its
joint, thereby raising the valve w from its seat, so as to allow gas from the meter,
which flows through the pipe u, to pass into the service-pipe v; and which said
outward direction of the gas is indicated by arrows.
The valve is kept open, so long as the catch & rests upon the peripheries of the
measuring out wheels, but on the notches, or inclined depressions on the peripheries
thereof becoming coincident, by the reaction of the discs, consequent of being
worked by the meter, then the catch or tooth e, fall and lie within the said
notches, which allow the valve to fall to its seat, and therefore shutting off gas in the
meter..
"
By this arrangement it is seen that the mechanism in being placed into a delivering
out position, opens the valve, but after the predetermined quantity of gas has been
allowed to pass through the valve, consequent upon so many rotations of the ineter
drum, the valve is closed, by the dropping of the catch within the notches of the
measuring out discs.
Figure 10 represents a modification of the valve, Figures 9 and 10, instead of the
escape of gas being prevented, by making the stalk into a water slide or work
immersed in water, or in an enclosing casing surrounding it, it simply works
through a stuffing box.
u is the outlet from the meter, and is the service pipe, through which gas is
allowed to pass for use, on the opening of the valve we, which is movable, by means of a
stalk., directed vertically down a casing or sleeve 23, the lower end of which
works within the middle of a barrel casing wt, which has a packing to, surrounding
the said lower part of the stalk w³, and adjusted in position by a gland-cap u³.
The stalk is connected at its lower end, to the said tubular casing, and works
with the upper slide 3, as seen in Figures 11 and 12 as hereinafter described so
that on the slide 3 rising, the valve stalk and valve with it, is also raised, causing
the barrel casing to be pushed over the lower extremity of the sleeve w³, and gas
which night escape down the hole wherein the valve stalk works, is prevented as
it would be intercepted by the packing as aforesaid.
Figure 11 represents in front elevation, with some of the parts broken away,
automatic sale and gas delivery mechanisin, constructed and arranged according to
another form of my invention. It will be seen that the valve for the shutting off
of gas from the meter, is shown closed, and with the catch or tooth within the
notches of both penny and shilling measuring out discs; and further, it will also be
seen that in this arrangement, the coin which is tendered in prepayment for the gas
to be delivered, has to be pushed home by an arm, worked by a lever, which is unable
to return until it has completely fulfilled its duty. In this said Figure 11, the coin
is shown dropped between the pulley jaws, and the pusher arm just in the act of

page_text: approaching its periphery, so as to pass it home in to the receptacle made to receive
it, and also to rotate the measuring out discs to an extent equal to one pennyworth
of gas as herein-after fully described.
Figure 12 represents a like view as Figure 11, but with the valve open, and the
parts in the positions which they respectively assume, ou the automatic sale and
delivery nechanism being in action, or impelled by the action of the gas passing
through the meter, whose motion is transmitted through the drum shaft.
Figure 13 represents partly in elevation, and partly in vertical section, the said
automatic sale and delivery mechanism, for gas supply, as in Figures 11 and 12.
The said view Figure 13 is taken upon the dotted lines A B Figure 12.
Figure 14 is a horizontal section, and top side plan of the said mechanism, taken
upon the dotted lines CD Figure 11.
Figure 15 is a back sectional view of the back enclosing casing of the mechanism,
exhibiting the guide slit, the back of the pusher arm and lever, with a raised rack
upon the face of the former, around the back and front of which, the returned end
of a spring travels, on the pushing in, and pulling out of the lever.
The coin which is tendered in prepayment for certain cubic metric gas delivery, is
shown pushed fully through the jaw-like pulleys, and in a position which it assumes
on falling.
Figure 16 represents the raised rack and spring, for preventing the lever from
being partially pushed home, and then withdrawn.
Figure 17 represents a like view, with the hooked end of the spring at the back of
the rack, while in Figure 16, the said hooked end is shown engaging with the teeth
of the rack.
The same letters of reference indicate corresponding parts in Figures 11 to 17, both
inclusive of the accompanying drawings.
a is a gas meter, provided with usual delivery or service pipe, and the gas passing
therethrough is controlled by the drum of the meter, which as previously described,
is impelled by the flow of gas, whose volume it measures. The chambers of the
drum are of known capacity, and its revolution, is controlled and indicated by trains
of wheel work, which register the quantity of gas upon dials placed for that
purpose.
In this form of my invention, the drum is stopped, only by the shutting off of
gas, which would otherwise flow into the service pipe.
.b is a lever, fulcrumed at b³, with a box or divided like end 62, consisting of two
plates, separated from each other, to the full distance of the breadth of a penny, and
with the end thereof, enclosed by a grooved pulley b¹; so that as the coin is pushed
home, as hereinafter described, it drops between the inside periphery of the said
grooved pulley, and the centre pin upon which the lever, turns.
Thus, the lever consists of a long and short arm; the one side for working, the
prepayment and gas delivery nechanism, and the other side for receiving the coin.
The view Figure 11 shows the partition between the coin receptacle, and the
mechanism enclosing casing broken away, as it will be seen from the transverse
sectional plan Figure 14, that the fulcrum at 63, works through the divisional wall,
which separates the said mechanisın enclosing casing, from the coin receiving
compartment.
6 is a loose pulley, turning upon a fixed axis 65, secured within the coin receptacle
casing a, of the front casing a; and upon the pulleys b¹, and 64, the coin c is
dropped, through the coin slit a2, when the pusher arm and lever have been pulled
back. The coin slit a², has a guide spout a³, for conducting the said coin above the
space between the rollers.
:
The coin is pressed home or between the pulleys, by the pusher arm d² of the
lever d, which is fulcrumed upon a pin centre d³ at its lower end.
The forward end of the pusher arm d², has a raised rack upon one side,
standing out from the face of the said end, as best seen in the back elevation
Figure 15, and in the sectional views Figures 16 and 17.
This rack is plain upon
its top edge, and toothed upon its under edge, with the teeth raking outwardly.

page_text: d' is a flat spring, with a hooked or returned end ; and which said end moves
alternately upon the plain top side, and the racked underside.
Thus, on the pushing in of the pusher arın d², and the carrying with it, of the
rack do, the teeth of the rack are made to wipe over the returned outer end d³, of
the spring do; and should the lever d be only partially pressed home, then it is
prevented from being again pulled out, by the said end of the spring confronting
the reverse way of the teeth, which thereby prevents the same being moved,
until the rack teeth have completely wiped or travelled over, the end, of the
spring as aforesaid; by this means, any attempt to fraudently obtain gas, other than
in a prescribed manner, is prevented. Further, the pulling out of the lever,
straightens out the spring, and makes the hooked end d, travel up the plain top
edge, and return to its normal position, in front of the lower end of the rack.
Thus, after the coin c, has been fully pressed home, by the edge of the part d', of
the pusher arm d², impressing itself upon the rim of the coin, the whole of the teeth
of the rack, have been inade to travel, and wipe over the end d, of the spring, when
the spring reaching the top end of the rack, slightly straightens out, and brings the
said end d', upon the curved part; so that on the lever d being pulled out, the spring
then further straightens out, and travels back on the plain top edge, in the direction
as indicated by the arrow, and on arriving at the bottom lower end, then the spring
shortens again, so as to bring its end, that it shall be able to act upon the rack teeth,
for the next forward movement of the lever.
It will be seen that the pulling out, and pushing in of the lever; for the uncovering
of the coin slit, which is done by the top part of the lever, and the pressing home of
the coin, makes the end of the spring, travel around both the plain and serrated parts
of the standing-up rack.
It will also be observed, that the pulling out of the lever is necessary, for the
uncovering of the coin slit a².
The long arm 66, of the lever b, has a catch or tooth e, upon its underside, which is
made to engage with notches h², 03, of a penny measuring out disc h, and a shilling
measuring out disc o, as best seen in the sectional plan, Figure 14, and in the vertical
section Figure 13; and fast upon the outside face of the penny measuring out disc h,
is a ratchet wheel g; and with the teeth of this ratchet wheel, the hooked end f², of
the swinging pawl f, connected to the arm b, of the lever b, engages. The hanging
pawl f, has a flat spring at its back, which on being moved upwardly, takes the
hooked end into position with the teeth, but on its descent, pressure being relieved,
it falls away from the teeth, by being hung out of the centre of motion.
The lever b, which is counterpoised by the weight of the valve and other auxiliary
moving parts, disposed above it, as herein-after described, carries a forked upright 67,
with fixed studs or pins 68, near its upper ends, which work within upright longi-
tudinal slots 1 of opposite slides 1, which are worked in an upward direction, by the
short end 2 of a weighted arin 2, fulerumed at 2b, having upon its extreme outer
end, a weight 2, which is limited in its motion, by a bracket stop 2d.
The slides 1, which are situated on the two opposite sides of the chamber or.
casing 82, of the mercurial slide 8, have short slots 1b, in their upper ends, wherein
opposite pins 3* carried upon the lower ends of upper slides 3, rest.
These upper
slides are connected by pins 3b, to the movable valve w, by a valve stalk w², the
cognate parts of which said valve stem and valve, will be fully described later on in
this specification.
The extreme outer end of the arm 60, of the lever b, carries an upwardly directed
and jointed arm be, with a long slot 610, at its upper end, wherein a pin 2, carried by
the weighted arm 2, works.
The bottom 6, of this slot, is for the purpose of reclosing the valve, on the pulley
jaws being opened to their fullest extent; that is, when the coin has got half way
through. So that should a coin, or any other object be designedly placed between
the jaws, for the purpose of holding them open, or the lever down, then the object is
frustrated, as the gas is thereby cut off, by the closing of the valve.
Thus, the introduction of a penny through the coin slit a², and on the same being
D

page_text: directed to the top of the short end of the lever, between the grooved pulleys, the
pressing inwards of the coin, depresses the short end 62, of the lever b, and raises the
long arin, and the tooth or catch e, from out of the notches 2, 63, of the gas
measuring out discs h, o, raises the forked upright 6', and its pin 68, above the lower
end of the slot 1 of the slides 1, thereby freeing the said slides from any downward
pressure, thus allowing the said slides to rise, and press upwards the valve w, through
the intervention of its stalk w³, and the upper slide 3.
The rising or upward movement, is effected by the pin 2 on the end of the short
arın 2, of the weighted arm 2 rising, by the falling of the weighted end 2 on the
same being free to move.
Thus, the bottoms of the grooves 1 follow the upward movements of the pins 68,
thus allowing the lower slides 1, to rise by the falling of the weighted end of the
arm 2, consequent upon the same being weighted and fulcrumed as represented; and
which said upward movement of the slide, raises the valve, by the rising of the
upper slides 3, which are connected with the valve stalk.
The partial rising of the arm 66, raises the upwardly directed arm 6º; and the
falling of the weighted arın 2, brings its pin 2, to the bottom 611 of the slot 10 of
the said arm 69; so that the further pressing inwards of the coin, and the consequent
changing of the distance between the grooved pulleys, further depresses the short
arm 62, of the lever b, and raises the long arm 60, of the said lever, and thereby still
further pressing upwards, the upright arm 6º, and raising the weighted arm 2, into a
neutral position, which thus allows the valve and valve stem, and upper slide 3 to
fall, and shutting off gas as represented in Figure 11.
The raising of the long arm 66 of the lever b, raises the swinging pawl f, and
makes its hooked end 2 engage with the teeth of the ratchet wheel g, and moving
the said ratchet wheel round to an extent of six teeth, which is an equivalent to one
twelfth revolution of the penny measuring out disc, and 144th of the shilling
measuring out disc.
The ratchet wheel g, and penny measuring out dise h, are tight upon an arbor i,
whose outer end 22, is reduced, and carries the penny indicating finger is, whose
rotation is made, in front of the dial 5; so that, the said wheels, and arbor, with
finger at its end, move together, and so does also a rear part it of the said arbor,
with a pinion n, fixed upon it, which engages with a toothed wheel pa, best seen in
the plan, Figure 14, for communicating notion to the shilling finger p, mounted
upon the sleeve end of a toothed wheel p².
The shilling measuring out disc o, runs free upon the rear part it, of the said
spindle i, and a reduced motion thereto is communicated, through the same train of
wheels that communicate a like motion to the shilling finger axis. Thus, motion to
the said disc o, and its finger p, is transmitted from the pinion n, through the
wheel, to the spindle pt, which has fast upon it, pinions p³, p, of like diameters.
The pinion p³ communicates motion to the shilling finger wheel p2, while the
pinion po, communicates a like motion to the shilling measuring out disc o, and
which notion is reduced in manner as aforesaid; so as to make the said finger and
disc, rotate only at a speed of 144th, that of the penny measuring out. disc,
and finger h, i³.
Working loosely upon the arbor i, is a tangential meter wheel q, driven from a
worm m³, of a meter axis m; and which said axis receives its motion direct from the
meter drum.
Disposed between the inner end of the sleeve q², of the meter wheel q, and the
ratchet wheel g, is a friction clutch g², by means of which, inotion from the meter,
is transmitted to the penny, and shilling measuring out discs, for taking them back
through the measured distances, which they have been moved, aforesaid.
The clutch consists of a dished-disc of metal, with inwardly directed slitt edges.
The function of the clutch, is to create sufficient binding power, between the face
of the ratchet wheel g, and the meter wheel q, that after the measuring out discs 5
have been advanced measured distances, equivalent to the amount of gas paid for

page_text: then the measuring out discs and driven wheels of the meter part move together,
at a rate proportional to the drum's motion.
Thus, the rising of the swinging pawl f, pulls round the ratchet wheel, and measur-
ing out disc, leaving the meter wheel q, which is in gear with the worm m²,
stationary, consequent upon it being unable to rotate, other than in the direction of
the meter drum; and after the said ratchet wheel has been moved to a measured
distance, it rerotates, or moves backward, by the clutch creating sufficient friction
between the wheels as aforesaid, as to make the whole move together, as if they were
rigid upon one shaft.
The mercurial slide 8, for making a sound joint, for preventing the escape of gas,
on the working of the valve, is as follows..
82 is an outer cylindrical casing, open at top, and closed at bottom, with slots
through its opposite sides, wherethrough pins 3b, pass, in connecting the slides 3, to.
the valve stalk carrier w³, to the lower end of which, the valve stalk w², is fixedly
connected.
The valve stalk passes through an inner tube or sleeve w¹, whose upper end carries
a dished seat w³, coming within the inside of the valve w, which surmounts its
stalk w². t is the valve casing, 2 the base thereof, wherethrough gas from the out.
let pipe u, connected with the meter, passes; so that the gas, when the valve is open,
as in Figure 13, passes in the directions, as indicated by the arrow, to the service.
pipe v.
The action of the machine is as follows:-
The coin tendered in prepayment for gas required to be consumed, is dropped into
the coin slit a², when the lever d is fully pulled back, and in dropping through, it
falls upon and between the rollers, and also between the sides of the divided short
end of the lever. When in this position, as in Figure 11, the lever d is moved
inwardly as indicated in the said Figure 11, with the presented edge d, of the pusher.
arm de pressing forcibly upon the upper edge of the coin, which on the lever being
further pressed forward, the pressure thus exerted, forces down the short arm b²,
turns the lever b upon its fulcrum 63, raises the long arm be, and takes the catch or
tooth e, from out of the notches h², o³, of the measuring out discs, raises the forked
upright 67, and its fixed studs or pins 68, freeing the slides 1 from downward pressure,
which are now made to rise, by the weighted arın 2, whose inner end 2* is connected
to the said slides 1, by studs 2; and which upward movement of the said slides,.
raises the upper slides 3, through the pins 3, working in the short slots 1b, and
slightly raises the valve stalk, and with it, the valve; this is the first movement, and
it may be here observed, that the falling of the weighted arm 2, has caused the pin 2°
to fall down the slot 610, to nearly the end 6. The continued and further movement
of the lever, brings the penny half way through, or midway between the rollers b¹, bt,
and which position creates a closing of the valve, by the continued upward move-
nent of the long arm 6ª, of the arın b, causing the bottom 611, of the slot 610 of the
upwardly directed arm 6º, to raise the long arm of the weighted lever 2, thereby
lowering the valve, by depressing the slides 1, whose opposite slots 1ª work over the
pins 68, and drawn down the upper slides 3, and with them, the valve stalk and valve,
so as to close the valve as in Figure 11, and cut off gas.
During the partial opening of the valve, and its closing as aforesaid, the raising
of the arin be, of the lever b, has raised the swinging pawl f, and made its hooked
lower end engage with the teeth of the ratchet wheel g, and pull the ratchet wheel
round to the extent of six teeth, and the measuring out disc h, through a distance
of one twelfth of a revolution, and the shilling measuring out dise, through a distance
of 144th of a revolution, bringing the respective notches ², 0³, into the positions
as indicated at Figure 12.
The motion of both penny and shilling measuring out discs, are communicated
and indicated by the fingers, p; and during the time that the said discs are
moved forward to a measured distance, the resistance offered by the clutch g², is less
than the force applied; so that the clutch remains quiescent with the meter wheel q;

page_text: but on the coin c being fully pushed home, through the rollers, it drops by its
own weight, into the coin receptacle, made to receive it.
The lever being now free of the coin, the weight pressure of the valve, and
the parts connected with it, causes the long arm 6 of the lever, to be lowered or
pressed downwards (with the short end b² raised) until the point of the catch or
tooth e, rests upon the peripheries of both penny and shilling measuring out
discs, as indicated in Figure 12; and in consequence of the slides 1 being free of
downward pressure of the studs bs, they rise by the falling of the weighted arm 2,
thereby raising the valve, through the intervention of the upper slides 3, connected
with the lower slides 1, and so allow. gas to flow from the meter, to the delivery
pipe v, until the notches h² and o³, of the penny and shilling measuring out discs h
and o respectively, become coincident, and under the point of the tooth or catch e,
when it falls into both notches, allows the long arm 60 to be lowered, which pulls
down the forked upright 67, and its pins bs, pulls down the slides 1, by coming at the
bottom of the slots 1", raise the weighted lever into a horizontal position, lowers
and closes the valve, through the intervention of the upper slide 3, connected with
the lower slide, and puts the parts into their normal positions as represented in
Figure 11.
The parts are prevented from falling too rapidly, by the fly 4, consisting of
radiating vanes, turning upon a fulcrum centre 4", with a pinion 4b upon it; which
gears with a toothed sector 5, fulcrumed at 5, and connected by pins 3º, to the
upper slides 3, by which means, the falling or lowering of the parts are only slowly
allowed to move into their pre-determined positions.
Figure 18 represents in front elevation, with some of the parts broken off, and in
vertical section, a portion of a gas meter, provided with automatic sale, delivery and
check mechanism, constructed and arranged according to another form of my said
invention; and the parts of which said mechanism, are shown in the positions which
they assume, on a penny being first tendered in payment for a predetermined quantity
of gas required to be delivered.
It will be seen that the said Figure 18, that the coin which is marked c, has been
dropped through the coin-slit, and in resting between the grooved peripheries of two
pulleys, disposed at a distance apart.
Figure 19 represents a like elevation and section, as that of Figure 18, but with the
parts of the said automatic sale and delivery check mechanism, in the positions which
they respectively assume, after the coin has been forced partially between the grooved
pulleys, as hereinafter described; and which said opening out of the pulleys, to the
extent of the coin's diameter, is the limit of movement which the said parts
make.
Figure 20 shows a like view, as that of Figures 18 and 19, but with the respective
parts of the automatic sale and delivery mechanism, in the positions, which they
assume, after the coin, tendered in prepayment of gas to be supplied, has passed
through the machine, and been conveyed into a receptacle made to receive
.it.
It will be observed, that the machine is now delivering out, by-the back rotation.
of gas measuring out wheels, and that the mechanism only commences to deliver or
act, after the coin has been fully passed through the machine.

casing, upon the dotted lines A B Figure 18, and Figure 22, is a transverse vertical
section on the dotted lines C D Figure 18.
Figure 23 is a back elevation of the coin lever, and partition of an enclosing casing,
where-through the spout of the coin-slit passes. This view is shown specially for the
purpose of representing the back of the pushing in lever; so that a coin or the lever,
must be pushed absolutely home, before it can again be withdrawn, as the pawl,
which is a spring arm, working upon the rack upon one side, and a plain part on the
other side, has to travel from front to back, and in a circular manner, in order that
the lever may be pushed in, for pressing the coins home, and pulled out, in order to
introduce others into the slit.

the saine in vertical section, on the dotted lines E F Figure 23.
Figure 26 represents an elevation and section of the spring pawl.
Figures 27, 28, 29 and 30, represent some of the main parts of the mechanism,
separately.
The same letters of reference, indicate corresponding parts in Figures 18 to 26
both inclusive of the drawings.
a is the gas meter, a² is a coin slit, and a³ is the guide of the spout, seen in the
back elevation Figure 23, and through which slit, and down the said spout, the coin.
falls and rests upon the short arm 6 of a coin lever b, whose long arm b6, is weighted
or counterpoised. The said lever is best shown in back elevation in Figure 23. The
short arm of this said lever, which is made up of sides, with a division or space between
them, carries a grooved pulley b'; and situated at a distance from this said pulley, is
a second grooved pulley b, turning upon a pin fitted within the fixed framing. Thus,
the pulley b, may be spoken of, as a fixed pulley, and the pulley b', as a movable
gas to be
pulley, and between these said pulleys, the coin deposited, in prepayment of
consumed, rests, before it is pressed home, which "act," measures out its worth of
gas, upon a measuring out wheel as herein after described.
The coin lever b, which is mounted on, and works with an axis 63, has made fast,
upon it, the inner end of a slotted arm x; and within the slot x2, of which, a fixed
pin f, carried by the main lever f³, works; and which said main lever turns upon an
end fulcrum f, and with the other end provided with a swinging pawl f, whose
lower end, is hooked inwardly, and engages with the teeth of a ratchet wheel g,
carried upon the front face of a penny, measuring out disc h, whose periphery is
provided with a notch or inclined gap, wherein the tooth or catch e, engages. This
e, of a.
tooth or catch carried upon the underside of the long arm
weighted lever e", whose fulcrum centre, is the cross axis 63 of the coin lever b,
and slotted arm x, 2, and jointedly connected to the long arm of the said lever e³, is
a forked upright link et, jointed at its upper end by pins e, which connect it to the
valve stalk w, by means of which, the valve is opened and closed.
The pin f, which is carried by the main lever f³, is made adjustable, and fixed
within the slot f³, by a screw nut f7; so that by increasing the distance between the
main lever fulcrum f, and the pin which controls the motion of a slotted arm x,
varying adjustments may be obtained.
Thus, if the pin f* be placed in the slot, nearer to the fulcrum centre f, then the
throw of the slotted arm will be less, and the movement required to be made, by
the rocking coin lever b, will also be reduced.
It will be seen that the pushing inwards of a coin c, between the movable and
adjustable rollers 61, 64, that the short end 62 of the rocking coin lever b, is lowered,
which on the turning of its fulcrum centre 6³, gives the same motion to the slotted
arm ; and in consequence of the pin f, being carried by the main lever f³, whose
fulcruin centre is at f, the said pin moves up the slot x2, and consequent thereby,
the main lever long arm f; and swinging pawl f, are depressed, taking the hooked
end f, of the said swinging pawl, at the back of the half-round snug 1, of a crank
lever 1, fulcrumed at 1, and having the end 1º, weighted, and being kept in a
determinate position, by a fixed stud or stop 1.
The hooked end f2, of the swinging pawl f, has a pin f8, which traverses the
convex of the snug 1, and then on the upward movement, it comes on the front of
the snug, and passes upon the inner and flat side of the said snug, thereby keeping
the hooked end always up to the teeth of the ratchet wheel, during the time that the
ratchet wheel is being advanced, and on the further rising of the said swinging pawl,
the swell f, upon its inner edge, comes against the axis of the shilling finger
transmitting wheel, and pulls the hooked end f2 from the teeth of the said
ratchet wheel.
Thus, by the oscillation of the main lever f, f³, the pin 8 is made to travel around
a snug, which when it is upon its front side, keeps the hooked end of the pawl up to
its work, which is then drawn away, by the swell as aforesaid, as it will be observed,

page_text: that the down movement prevents the hooked end from wiping over the teeth, as is
common with ordinary pawls; and further, the said pawl is pressed inwards by a flat
spring flo
The downward movement of the main lever, distends a coiled spring 2, disposed
near its joint end, and the top of the enclosing casing.
The rear end of the main lever, carries a rack 3, which engages with a pinion 3*,
on an axis 3b, which has fast upon it, a toothed wheel 3º, which gears with a
pinion 4, whose axis carries a fly 4, which by its rapid rotation, encounters
the resistance of the air, and so prevents the return of the moving parts too
precipitously.
d is a lever, fulcrumed at d³, for pushing inwards a coin pusher d², whose inner
end d, impinges upon the edge of a coin. The upright inner edge of the said
lever d, covers up the coin slit a², and prevents the introduction of moneys, until
the pusher arm, has been wholly withdrawn, so as to admit of the coin tendered in
payment of the quantity of gas required, to be properly directed to the top of the
grooved pulleys as aforesaid.
The back of the pusher arm d², is provided with a rack and pawl device, for pre-
venting the lever from being pulled back, or the pusher arm withdrawn, until the
coin has been pushed or forced fully home; that is, the lever and the pusher arm
must make their allotted inward notion, before they can be withdrawn, or pulled
back, and which is done, by making the spring pawl, which is nothing more than
a catch, traverse both the toothed and plain side of a rack, in a circular manner.
d is a box rack, with teeth ds, upon its one side, and plain upon its inner
side do, as best seen in Figures 23, 24 and 26.
The top do of the said inner side is inclined inwards. is a spring pawl,
with returned or hooked end d', and when in its acting position, its tendency is to
spring outwards, but not sufficiently far to interfere with it, properly wiping over
the teeth of the rack. Thus, when the lever d is pushed inwards, for the pressing
home of the coin, the arm de, causes the teeth 8 to be moved past and under the
returned end d7, of the spring pawl d, until it arrives past the top tooth, when it
falls and springs inwards to a little inward of the incline 0, when the outward
movement of the lever now brings the pawl at the back do, and in consequence of
it travelling up the incline 1, it has been bent inwards, and on arriving at the
gap d, it resumes its normal condition, and springs outwards, with its underside
resting at the bottom of the incline of the bottom tooth; so that by the pushing in,
and drawing out of the lever, the hooked end is brought, and made to travel up
the inclines of the teeth, click over the shoulders, and as each incline bends the
pawl outwards, so that on coming at the top of the incline of the top tooth, it
springs inwardly through the gap ", to the commencement of the incline at the
back, and which incline on being drawn forward, with the rack, bends the spring
pawl inwards, until it has again come to the gap 12, and completed its circular
The cross section of the end d', of the spring pawl do, is shown at
inovement.
Figure 26.
It will be observed in referring back to the lever e², of the tooth or catch C₁ and
by whose upward motion, the valve stalk w, is raised and lowered, that it is simply
an arm, loosely turning upon the axis 63, as a joint centre; and is raised simply by
the incline of the notches 2 and o the latter hereinafter described.
On the advance movement made by the gas measuring out discs h and o, conse-
quent upon the pulling round of the ratchet wheel, the tooth or catch e, is removed
from the notches, on to the peripheries of the discs respectively, and on the said
dises moving backward to their alloted cubic metric distances, the said tooth or
catch falls again within the coincident notches, lowers the valve stalk by the pulling
down of the upright e, and so shuts off the gas, or closes the valve, which is carried
at the summit of the stalk.

is
The penny measuring out disc h, which has upon its face, the ratchet wheel
tight upon the arbor i, whose outer end 22, is reduced, and carries the penny
indicating finger i³, whose rotation is made in front of the dial 25; so that the said

page_text: wheels g, h, and arbor with finger at its end, move together, and so does the
rear part of the said arbor it, which has a pinion n fast upon it, which engages
with a toothed wheel p5, as best seen in the plans, Figures 21 and 22, which
communicates the motion of the finger axis to the shilling disc e, loosely running
upon the axis it, and which shilling disc has a toothed wheel of fast upon its
back; and which said motion to the shilling disc and its finger p is communicated
from the pinion n, on penny disc arbor, to a toothed wheel p and spindle p', carrying
pinions p p.
The pinion pe transmits the motion of the spindle p₁, to the wheel o, o², at
the back of the shilling disc o, and so gives to the shilling disc 144th of a revolution
to every one twelfth of a revolution made by the penny disc h.
Motion to the shilling finger p, is made through the large loosely mounted
toothed wheel p², whose outer end has a sleeve, upon which the said finger is
carried.
Working loosely upon the arbor i is a tangential or toothed meter wheel q, driven
from a worm m², of a meter axis m, and which said axis receives its motion direct
from the meter drum.
Disposed between the inner end of the sleeve q2 of the meter wheel q, and the
ratchet wheel g is a friction clutch 2, by means of which, motion from the
meter is transmitted to the penny and shilling measuring out discs, for taking
them back through their measured out, and allotted distances, through which
they have been moved forward, and which distances represent a fixed quantity of
gas, which is allowed to be consumed, in exchange for the coin passed through the
machine.
The clutch consists of a dished disc of metal, with radially directed slitt edges,
so as to create sufficient binding, for the moving together, or in common with
another, the parts in juxta position to its two opposite faces.
Thus the function of the clutch is to create sufficient binding power between
the face of the ratchet wheel g, and the meter wheel q, that after the measuring
out discs have been advanced measured distances, equivalent to the amount of
gas paid for, then the said discs, and driven wheels of the meter part, move together
proportional to the druin's motion.
Thus, the pulling up of the swinging pawl f, and the advancing of the ratchet
wheel g, through a measured distance, the meter wheel q remains quiescent, as it
cannot rotate in a reverse direction, to the motion of the ineter drum, as it is pulling
against the worm m²; so that the friction of the clutch, makes fast the measuring
out part of the mechanism, when it is to move, in the same direction as, and with the
drum of the meter.
The action of the said automatic sale and delivery gas mechanisin is as
follows:-
:-
On a penny being passed through the coin slit a², when the lever d, and pusher
arm d is pulled back, the coin falls by its own weight into position between fixed
and movable rollers ₁; and when in this position as represented in Figures 18
and 23, the lever d is forcibly pushed inwardly, when the extreme end of the
pusher arm d², impinges upon the rim of the coin, and forces the said coin
between the rollers 61, 6, which act, or forcing inwards of the said coin, depresses
the short arm and rollers b', of the coin lever b, raises the weighted end 66, and
also turns its axis and with it the slotted arm x, whereby through the
intervention of the pin f, working within the slot 2, that the main lever f³ is
lowered upon its fulcrum centre depressing the swinging pawl, and with the
pin at the hooked end f, made to pass around the outside of the snug 1 at the top
of the arm 1 of the weighted cranked lever, which is fulcrumed at 1b, and on the said
pin f arriving at the bottom of the said snug, the pressure of the spring f10, takes
the point of the hooked end as aforesaid, into a tooth of the ratchet wheel I, and
when in this position, the coin having been forcibly pressed completely home, or
inwardly from between the rollers, the spring 2, which became distended, on the
lowering of the main lever, now contracts itself, drawing upwards the main lever ³,

page_text: and with it the swinging pawl f, which being engaged with the tooth of the ratchet
wheel g, advances the ratchet wheel to an extent of six teeth, and with it, the penny
measuring out disc h, and shilling measuring out disc o, through a distance of the
one, equal to one twelfth of a revolution, and with the other through 144th of a
revolution.
The upward movement of the hooked end f2, causes the pin f8, to travel up the
inside of the snug 1, and by the crank lever being weighted, the tooth thereby is
constantly kept up to the face of the ratchet wheel, until it arrives above the top of
the snug, when it is drawn from it, by the swell fº, being drawn against the axis 7,
which brings the pin 2, to the top of the front side of the said snug, ready for the
.next downward movement.
The advancing forward of the penny measuring out disc, and the shilling disc,
causes the point of the tooth or catch e, which acts in common to both discs, to be
withdrawn up the inclines of the notches or depressions h², o³, to the peripheries or
edges of the dises, thus raising the tooth or catch lever e², upon its fulcrum or hang-
ing centre, and in consequence of its outer end being raised from a lower, to a higher
level, by the forcible displacement of the tooth from the notches, the forked upright
link e, is consequently also raised, and the valve, surmounting the valve stalk wis
opened, thereby admitting gas to flow from the meter pipe, to the service, until the
notches of the measuring out discs have returned to their normal and coincident
positions, and opposite the tooth e.
The parts which have resumed their normal positions, as in Figure 18, have been
prevented from passing back too precipitously, by the rack 3 engaging with the
pinion 3, and through its axis 3b, to the toothed wheel 3°, which rotates the pinion 4b,
'upon whose axis the fly 4 is fixedly secured, and thereby rotated; and whose motion
is regulated, by the resistance of the air.
The advance movement of the ratchet wheel as aforesaid, turns the finger 3, through
a graduated distance in front of the dial, while the shilling finger p, and disc o, are
turned through corresponding reduced distances, by the pinion n, engaging with the
toothed wheel p, to the spindle p, and from thence through the pinions p³, 76, to
the toothed wheel o² of the disc o, and the toothed wheel p², of the sleeve of the
finger p. The advance movements of the discs being made in a direction contrary to
the motion of the meter drum, and as the force applied is greater than the pressure
of the clutch, then the ratchet wheel g, and measuring out wheel h, after having been
moved through their allotted distances, the meter drum now moving, communicates
its motion to the train of wheels, and through the clutch g2, to the measuring out
wheels, carrying the said wheels back to their normal positions; and until the catch
or tooth e, of the catch lever e², comes opposite the notches 2, 03, when the said
catch moving slowly, down the inclines, gradually shuts off the gas, by the lowering
of the lever, upright link e, valve stalk w, and valve, thereby cutting off communica-
tion between the pipe leading from the meter, to the service pipe.
Figure 31 shows a modified form of the said arrangements, from Figures 18 to 22.

the lever e²; and which stalk passes through a packing us, situated within a gland us,
on the underside of the outlet u leading from the meter; and by the raising of which
said valve, gas is allowed to pass to the service v.
d is the lever, and d the pusher arm, whilst 64 is the fixed pulley.
It will be thus seen that the arrangement Figure 31 is only a simplified form of the
arrangement Figures 18, 19 and 20.
Thus, on placing a penny through the slit a³, it drops upon the grooved
pulleys 61, 6, and on the pressing inwards of the pusher arm of the lever d, the
coin is forced home between the rollers, which depresses the short arm 62 of the
lever b, turns its joint centre 63, and with it raises the lever f³, and pawl f, whose
hooked end engages with the teeth of the ratchet wheel, pulling it round to the
extent of six teeth, and also advances, or winds up the penny and shilling measuring
out discs h and o, which causes the point of the tooth or catch e, to travel up the
inclines of the notches 2, 3, (the latter not shown) until the said tooth or catch
rests upon the peripheries of the said discs; which change of elevation raises the
lever e, valve stalk w² and valve w, thus allowing gas to pass from the gas meter
outlet u, to the service v; and as the whole of the other parts of the automatic sale
and delivery mechanism are alike to those of Figures 20 to 30, the re-rotation of the
measuring out discs, on the pennyworth of gas being consumed, brings their notches
opposite the tooth or catch e, when by the change of elevation, from the rims to the
hottoms of the notches, the valve is lowered by the falling of the valve stalk.

ROWLAND WILLIAM BROWNHILL 44 High Street Aston New Town near
Birmingham Mechanical Engineer do hereby declare the nature of this invention
to be as follows:-
My invention consists of an apparatus for receiving cash for gas supply either in
small or large quantities, the object being to enable gas companies to supply gas by
prepayment at low prices, & so put gas supply upon an equal basis for competition
with Oil lamps.
I construct my receiving apparatus so that by putting a penny or coin or coins
through an aperture provided for this purpose in combination with a gas meter, when
the coin or coins are put into the aperture the meter commences & continues to work
until the quantity of gas to be supplied in value for the coin or coins is delivered for
freeing the meter by a coin or equivalent, I use a disk which is geared to the meter,
and worked by the meter, upon which is a moveable periphery held to the disk by
friction, and which said periphery can be moved upon the disk by seperate gear
(independant of the motion of the disk by the action of the meter as before described)
by the action of a coin or equivalent being placed in the receptacle, upon the outside
edge of the periphery a groove is made for two purposes, first when the lever which is
actuated by a coin rests in this groove, the meter is at rest, the action of putting
a coin in the receptacle lifts this lever out of this groove, and by the same motion
advances the moveable periphery round the disk a certain distance and at the same
time liberates the meter which is impelled by the pressure of the gas until it returns
to the same position as at first, when the lever falls into the groove as at first during
the time of this action the quantity of the gas passed through the meter is the
value agreed for tho coin, without waiting for the meter to stop by the above action
any further number of coins may be placed in the coin receptacle to be paid out
in value in gas, until the moveable periphery has nearly completed a circle round the
disk, Second use of the groove in the moveable periphery, when it has nearly com-
pleted a revolution the groove comes under the action of another lever which falls

page_text: into it by a decline, this lever is pivoted near the centre and the other end operates
upon a shutter which closes the apperture from the reception of any further coins
until the moveable periphery with the groove is again retired by the action of the
meter in doing so it lifts the lever again and the apperture for the reception of coin,
each operation of putting in a coin will be shown upon a dial, worked by gear from
the moveable periphery, which will show at a glance how much cash has been
deposited in the receptacle for which gas is still to be supplied.
The methods of stopping the meter by the lever when it falls into the groove as
before described, may be either closing the inlet or the outlet passages of the gas
through the meter by valves actuated by this lover, or by arresting the advance of the
meter for the latter method I propose to work another disk sido by side by the before
described disk with the moveable periphery and worked from the meter by gear at a
speed slower than the meter, also with a groove upon its periphery, so that the same
lever may drop into it this lever being made wide enough for both disks, but the lever
cannot drop into this second disk, until releived by the first named disk with the
moveable periphery, this last mentioned disk, may also have a frictional periphery or
attached with a spring so as to take off any shock when the lever falls into the grove
and suddenly stops the meter. For receiving the coin I use a lever pivoted at a point
between the two ends to a rachet wheel. At one end of this lever is the balance
weight, at the other end the rescepticle box for the coin; when a coin is dropped into
the rescepticle box the lever at once falls and carries with it the rachet wheel by a
fall upon the same shaft upon which the rachet wheel is fixed, is fixed a spur wheel
to gear into the moveable periphery of the first named disk to give motion to it.
A wheel is also fixed upon the centre of the lever to gear into the wheel upon the
stop lever shaft to actuate the stop lever.
My method of releasing the coin from the rescepticle box. On the end of the lever
the bottom of the rescepticle box is closed by a ballanced bottom in the form of a
lever, one end of which forms the bottom of the rescepticle box, and the other end of
this lever when it falls to the bottom catches a projected balanced lever fixed to the
outside case.
When the coin is put into the rescepticle box, the lever falls, the bottom of coin box
is opened by the projecting balanced lever fixed to the outside case, and the coin falls
into the cash box below; the main lever then returns, the balanced projecting lever
lifts up to allow the coin box lever to pass, the ordinary index upon the gas meter
giving the quantity of gas consumed and so check the amount of cash deposited
for gas.

page_text: I, ROWLAND WILLIAM BROWNHILL of 17 Temple Street, Birmingham, in the
County of Warwick, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to an automatic sale, and delivery gas meter, or a gas meter.
provided with mechanism or apparatus, for giving out a determinate quantity of gas,
on the same having been previously paid for, by depositing a coin or coins within
a receptacle, or through a slit made in the enclosing framing of the said automatic
means.
Thus the automatic sale and delivery means, in connection with a gas meter,
consists essentially of a counterpoised lever, which is controlled by a coin or coins,
introduced as prepayment, for an amount of gas to be supplied; and which lever,
through links or the like, gives a proportionate or partial backward movement to a
disc or discs, having inclined notches cut within their peripheries, within which a
catch or cross bar lies, when the meter is at rest.
The other parts consist essentially of trains of wheel-work, which are driven directly
from the druin of the meter, and through some of them, communicate the necessary
backward movements to the discs, which are the gas measuring out means.
discs are coupled for their backward movements, by suitable devices, as herein-after
described.
These
Figure 1 represents in front elevation, a portion of a gas meter, provided with
automatic sale and gas delivery mechanism, constructed and arranged according to
one part of my said invention.
Figure 2 represents partly in elevation, and partly in vertical section, the said
mechanism, meter and auxiliary parts, in connection with them, by which means, a
predetermined quantity of gas is measured out, and allowed to flow through the
meter, after a coin which is the equivalent in payment therefor, has been dropped
through a slit, and from thence passed into a balanced receptacle placed thereunder,
to receive it. The said mechanism figure 2 is shown in the position which it assumes,
when it is in its normal position, or in a position of non-supplying. It will be
seen also, that the catch or stop is resting within the slanting notch, made within
the periphery of a measuring out penny disc; that is, a disc which indicates twelve
pennyworths of gas, if it makes one rotation.
Figure 3 represents a like view as figure 2, but with the parts of the mechanism
in the positions which they assume after a coin has been dropped into the receptacle
made to receive it, in prepayment of a predetermined quantity of gas as aforesaid.
The coin thus deposited, is shown dropping through the now open bottom of the

page_text: movable coin box (in dotted lines) after it has done duty, in giving a proportionate
or partial-rotation to the measuring out discs, and releasing the going wheels, and
drum of the meter.
Figure 4 is a top side plan, and part horizontal section of the said mechanism
figures 2 and 3, thus showing more clearly the positions of the gas measuring out
discs, and other parts, with respect to the trains of wheels, which communicate motion
to the indicating finger axes.
Figure 5 represents partly in transverse vertical section, and partly in end elevation,
the said mechanism and auxiliary, and attendant parts. This view shows clearly the
drum axis of the meter, from whence the motion for the taking of the parts of the
mechanism back to their normal positions as hereinafter described, is derived.
Figure 6 represents the combined ratchet wheel, and penny measuring out disc
or wheel, and with a counterpoise pinion axis, bracket and intermediate wheel, which
latter gears with the teeth of a toothed annulus, carried by, and made in one piece
with a toothed wheel, whose only motion is received from the main axis, which is
driven from intermediate wheels, between the drum axis. This combined annulus
and toothed wheel, is represented at figure 7, and with a counterpoised pinion in a
position which it assumes, after the measuring out disc, upon whose face it is carried,
has passed through a distance of one twelfth of a revolution, and an equivalent to a
distance equal to one penny-worth of gas.
Figure 8 represents front elevations of the penny-measuring out disc, and the
shilling measuring out disc, shown one before the other. The front top part of the
former, is broken away to exhibit the slanting notch, in the latter. This view also
shows the relative positions of the notches, with respect to each other, after a coin has
been deposited, for the prepayment of a certain quantity of gas.
The same letters of reference indicate corresponding parts in figures 1 to 8.
a is a gas meter, provided with the usual delivery, or service pipe, and the gas
passing therethrough, is controlled by the drum of the meter, which is driven by
the flow of gas, whose volume it measures. The chambers in the drum are of
known capacity, and the revolutions are conveyed to a distance by trains of wheel-
work, and then registered upon dials.
b is a counterbalanced lever, moved by the weight of a descending coin, placed
within a receiving box 63, placed at one end of the said lever, which is fulcrumed
at 6, near the other end, thus making a lever with arms of unequal lengths with
the coin box at the end of the longer arm, and a swinging counterpoised weight 64
at the end of the shorter arm.
The mouth of the coin box 62, is hopper shaped, and comes under and opposite
the lower open end of a depending guide a³, leading from a guide slit a, situated
at the upper part of the enclosing casing a', of the automatic sale and delivery
mechanism of the meter as best seen in figures 2 and 3.
The coin box 6' has an open and balanced bottom b³, consisting of a jointed and
counterpoised short arm, fulcrumed at 6, to a bracket extension of the lover; and
which said arm extends a short distance under the said open bottom. The other
end 6' is heavier than the combined weights of both coin and short arm; so that
if a coin be dropped through the slit into the coin box, the long arm, and coin
box at its end, descends and brings the counterpoised, or weighted end b, of the
-balanced bottom, suddenly against a fixed coin liberator 68, secured to the inside
of the enclosing casing.
The momentum thus acquired, by the falling boss end of the lever, raises the
weighted end 67, and turns outwardly the bottom, thereby liberating the coin C which
being no longer supported, falls by gravity through the open bottom of the box, into
a receptacle or drawer, placed thereunder, to receive it, as represented in figure 3.
While the coin box end of the lever descends, the other, and short arm, rises,
and as its fulcrum pin turns with the lever, a rising motion is given to the connecting
rod d, and the jointed arm e³, whose other end is connected to the upper end of
the said rod, and with its other extreme end e³, jointed to the framing. The
connecting rod at its lower end is connected to the short arm d³.

page_text: The arme has a swinging hooked ended pawl f, with a flat spring at its back,
for taking it up to the teeth of the ratchet wheel g, which is disposed upon the
face of a gas measuring out penny disc h, whose periphery has a notch or gap ³,
wherein the catch e, carried by the arm e², drops or lies, when the machine is at rest.
The ratchet wheel g, and measuring out disc h, are fast upon an arbor i, whose
outer end is reduced, and carries a finger ³, which indicates before a dial j
figure 1, the number of pennies up to 12, which have been deposited into the
receiving or cash box k of the apparatus; thus, if one penny be passed through
the slit, and the apparatus worked, then the finger i, will have traversed one twelfth
the dial field.
The arbor is extended rearwards, from the back of the penny measuring out
disc, and working and taking its bearing in the middle of a ratchet wheel l, which is
made fast with a spur wheel m, which is driven from the drum axis m², through
intermediate wheels and pinions m³ m*.
Made fast upon the extended end of the, arbor i, is a pinion n, through which
motion is communicated to the shilling measuring out disc o, and shilling finger p,.
which is carried by the neck of a toothed wheel p², driven by a pinion p³ of a spindle p₁,
fast with a toothed wheel p', which gears with the pinion n as aforesaid.
The shilling measuring out disc has a spur wheel o' fast upon its back face, which
is driven by a pinion po, on the axis p*; and further, the shilling measuring out disc o
has a notch o, like a notch in the periphery of the disc h, wherein the catch e
lies, on its notch and the one cut within the periphery of the penny disc h, becoming
coincident.
The shilling disc o, and the spur wheel o at its back, is loose upon the extended
arbor and disposed between the pinion n, and the back of the disc h.
The catch e, when it lies within the notches 2, o³, it then necessarily lies also
within the teeth of the ratchet wheel 7, and thereby fixes the drum of the meter in a
non delivering position, as will be hereinafter more fully described.
Working loosely upon the arbor i, is a toothed wheel g, having formed within its
inside face, a toothed annulus q, upon the face of which, a pinion 92, through the
intervention of an intermediate wheel g³, carried by a bracket 9*, rolls. This pinion
has fast upon its axis, a counterpoise weight go, turning upon a pivot go, working
within a bearing, made within the face of the ratchet wheel g.
The bracket g is also carried by the ratchet wheel; so that on the ratchet wheel
being moved forward, by the rising of the pawl f, through the descending movement
made by the long arm of the lever b, the intermediate pinion g³, is made to roll upon
the face of the toothed annulus q, to an extent equal to the amount of gas which
is to be allowed to be given out through the meter, in lieu of the coin or coins
deposited.
The pinion g³ which is fast with the weight go, forms a clutch for making fast the
wheels q, q, with the ratchet wheel g, disc h, arbor i, , and pinion n, and shilling
disc, toothed wheel at its back, and other intermediate wheels and pinions, working
in connection with the shilling finger p.
9,
Thus, the upward movement of the connecting rod d, imparts motion to the ratchet
wheel g, to the extent of six teeth, and raises the cross catch e, from the notches 2, 03,
and teeth of ratchet wheel l, while the backward movement of the ratchet wheel
makes the pinion g³, roll upon the edge of its intermediate pinion g³, which in its
turn rolls upon the teeth of the toothed annulus q³, which remains quiescent, as it is
in direct communication with the meter wheel m, through the pinion 12, wheel 13,
pinion, wheel, pinion 16, wheel l, and smaller toothed wheel 18, which latter gears
with the spur wheel q.
Thus, as the ratchet wheel moves forward, to the extent of six teeth as aforesaid,
the pinion, intermediate wheel, bracket and counterpoised weight move round with it,
and if a penny be the sum deposited, then the said ratchet wheel and parts carried by
it, will move round to the extent of one twelfth of a revolution of the penny disc,
which will be indicated upon the dial, by the finger ³, moving at the same time, as it
is on the axis of the parts as aforesaid.

page_text: The counterpoise weight go of the pinion g³, rolls over with the pinion g³,
and
performs a tumbler like action, and whose function is to take the pinion upon the
annulus, to the extent of one complete rotation, which might not take place, as slight
differences in the movement of the ratchet wheel, might be imparted, by the motion
of its hook ended pawl.
The face wheel has pivoted upon its face, a lazy weight 9', which is passive in its
nction, but counterpoises the action of the weight g
It will be observed that the wheel p³, carrying the shilling finger p, traverses the
dial for a penny, to the extent of one 144th of a revolution; and which said wheel p'
is speeded down by the reduction wheels p³, p³, p.
The action of the apparatus is as follows.-
On a penny being placed through a slit a², in a framing enclosing the automatic
sale and gas delivery mechanism, it passes down the mouth of the guide a³, and is
deposited in the coin receiving box 63, which now becomes heavier than the parts
carried, and in connection with the short end of the lever b; so that the coin box
descends into a position as represented in figure 3, with the weighted end 67, of the
balanced bottom 66, of the said box, striking itself against the coin liberator 68, which
causes the said balanced bottom to open outwardly, and liberate the coin, which being
no longer supported, falls by its own weight, into a box below, for to receive it.
The downward movement of the coin box 62, presses upwards the connecting
rod d, and raises the arm e³, so as to take the catch e, from out of the inclined notch ²,
of the penny measuring out disc h, notch o³ of shilling measuring out disc 0, and from
the teeth of the ratchet wheel 1, while the upward movement of the swinging pawl f,
after the catch has been raised out of the notches, and from between the teeth as
aforesaid, (which thus liberates the meter, and leaves free the discs) gives a pro-
portionate or partial-forward rotation to the ratchet wheel g, and disc h, to an
extent of one twelfth of a revolution, and gives the shilling disc o, a proportionate
or partial-rotation to the extent of 144th of a revolution, which diminution of speed
is acquired, by being driven from the pinion n, on the same arbor, as carries the
penny disc, and ratchet wheel. This one twelfth movement of the arbor i, gives to
the finger, a like movement in front of the dial, while the finger p, is made to
take only 144th movement of the said finger; and further, the said backward move-
ment of the ratchet wheel g, carries with it the pinion g², g³, bracket g, weights g³, g',
and makes the intermediate pinion g³, roll upon the toothed face of the annulus,
to an extent equal to the ratchet wheel; and on it making one complete rotation,
as represented in figure 3, after the manner of a sun and planet movement, the
wheel and annulus q, which are loose upon the arbor i, are now locked with the
ratchet wheel, and parts moving with it; and as the annulus and toothed wheel 9, 9³,
are driven by the meter drum, it necessarily follows, that instantly the said toothed
wheels and parts carried by it become locked, then a counter movement equivalent
to the meter drum movement takes place, and carries the penny measuring out
disc, and ratchet wheel back, until it comes opposite the underside of the catch e;
and as the motion of the shilling disc is governed by the motion of the penny disc,
then, after a pennyworth of gas has been consumed, the two discs turn back to their
former positions, with the notches ³, o³, becoming coincident, which then allows the
catch or tooth e, which has subsequently-been-pressing upon their peripheries, to fall
and lie within the said notches, and between two of the teeth of the ratchet wheel 7,
thus stopping the meter, and allowing the coin box 63, to rise to a further extent
equal to the depth of the notches as aforesaid.
It will be further observed, that after the coin has descended, and allowed the coin
from it to fall, it then returns, not quite to its former position, as the catch e rests
upon the peripheries of the discs / and o.
When more than one coin is placed within the coin box, it is necessary that the
same should rise before a second one is placed therein; and when, say, a dozen coins
have been deposited, the tumbling weight, and its pinion g³, 9, makes twelve
tumbling revolutions, which brings the notch of the penny wheel at the top, and in
a position from whence it started, but as the shilling disc has been advanced to an

page_text: extent equal to one twelfth of a revolution, the notches are of different positions, so
that the catch rests upon the periphery of the shilling disc, and until these notches
become coincident, the meter will deliver gas, equal to a back rotation of the penny
disc, and a twelfth back rotation of the shilling discs; so that it will be seen that
143 coins can be intermittently deposited, without the notches in the discs becoming
coincident, and gas given out to the value of 143 pence.
Figure 9 represents my said invention provided with a valve, for cuttingjoff, and
admitting of the flow of gas, instead of by stopping the drum of the meter, as in
the previously described arrangement. The whole of the mechanism parts with the
exception of the ratchet wheel 7 are the same.
Thus a is the meter, a³ is the guide of the slit, and a¹ the enclosing casing of the
antomatic sale and delivery mechanism. 6 is the counterpoised lever, is the coin
box, b' is the bracket at its end, 6s the centre of the lever, (the swinging counter-
poised weight is not shown,) is the balanced bottom of the coin box, 66 is the
fulcrum pin, and 6' a weighted end, and 8 an upwardly directed coin liberator, which
as aforesaid, strikes the underside of the weighted end 67, on the descent of the coin
box-d is the connecting rod, connecting the arm e², with a lever b, and which arm
is fulcrumed at ee is the catch or tooth shown upon the peripheries of both
measuring out discs and o-g is the ratchet wheel upon the face of the disc t, with
the teeth thereof, the hooked end of the pawlf engages, and which pawl is pressed
home by a spring arranged at its back for that purpose.
The discs and o have notches within their peripheries, whilst motion is com-.
municated to the fingers, p, which traverse the lial field at their backs.
Motion is communicated to the mechanism from the drum of the meter, by spur
wheels or pinions r,, which former is fast upon an axis with a pinion at its
end, which gears with a toothed wheel m, and from thence to the trains of wheels.
of the mechanism as aforesaid. The shaft of the wheel extends vertically
downwards within a sleeve, and is driven and connected with the drum of the
meter.
In the said figure 9, of which figure 10 is a longitudinal vertical section, the.
mechanism, and the enclosing casing, with dial upon its front, is shown in elevation,
but the water slide which prevents the escape of gas from the service leading from
the meter, is shown in complete section.
s is a water slide, consisting of an outer tube 3, open at top, and closed at
bottom, by the said bottom end screwing within a socket t³, made upon the top of
the valve casing t.
u is the outlet from the meter, and is the service pipe, wherethrough gas is
allowed freely to pass by the opening of a valve w, carried by a stalk w³, worked by a
jointed arm a, jointed at a³, and whose free end³ rests upon the outer end of the
arm e².
The stalk w³ of the valve, carries an inner enclosing tube w³, and works up and
down within water placed within the interior of the outer casings, wherein water or
mercury is placed, so as to form the seal, in preventing the escape of gas through the
gland w³, of which the inner tube w¹ directly surrounds the valve stalk.
The lower extension of the valve stem is guided within a socket (³, of which the
dish shaped top t forms the valve seat.
Thus on the placing of a coin through the slit a², the coin-box 6 descends, and>
raises the connecting rod, which lifts the arm e³, and the valve stalk arm & upon its
joint, thereby raising the valve w from its seat, so as to allow gas from the meter,
which flows through the pipe u, to pass into the service-pipe v; and which said
outward direction of the gas is indicated by arrows.
The valve is kept open, so long as the catch e rests upon the peripheries of the
measuring out wheels, but on the notches, or inclined depressions on the peripheries
thereof becoming coincident, by the reaction of the discs, consequent of being
worked by the meter, then the catch or tooth e, fall and lie within the said notches,
which allow the valve to fall to its seat, and therefore shutting off gas in the meter.
By this arrangement, it is seen that the mechanism in being placed into a delivering:

page_text: out position, opens the valve, but after the predetermined quantity of gas has been
allowed to pass through the valve, consequent upon so many rotations of the meter
drum, the valve is closed, by the dropping of the catch within the notches of the
measuring out discs.
Figure 10 represents a modification of the valve, figures 9 and 10, instead of the
escape of gas being prevented, by making the stalk into a water slide or work
immersed in water, or in an enclosing casing surrounding it, it simply works
through a stuffing box.
u is the outlet from the meter, and is the service pipe, through which gas is
allowed to pass for use, on the opening of the valve w, which is movable, by means
of a stalk w³, directed vertically down a casing or sleeve w³, the lower end of which
works within the middle of a barrel casing w, which has a packing w³, surrounding
the said lower part of the stalk w³, and adjusted in position by a gland-cap u. The
stalk is connected at its lower end, to the said tubular casing w, and works with the
upper slide 3, as seen in figures 11 and 12 as herein-after described so that on
the slide 3 rising, the valve stalk and valve with it, is also raised, causing the barrel
casing to be pushed over the lower extremity of the sleeve w³, and gas which might
escape down the hole wherein the valve stalk works, is prevented as it would be
intercepted by the packing as aforesaid.
Figure 11 represents in front elevation, with some of the parts broken away,
automatic sale and gas delivery mechanism, constructed and arranged according
to another form of my invention. It will be seen that the valve for the shutting off
of gas from the meter, is shown closed, and with the catch or tooth within the
notches of both penny and shilling measuring out discs; and further, it will also`
be seen that in this arrangement, the coin which is tendered in prepayment for
the gas to be delivered, has to be pushed home by an arm, worked by a lever,
which is unable to return until it has completely fulfilled its duty. In this said
figure 11, the coin is shown dropped between the pulley jaws, and the pusher arm
just in the act of approaching its periphery, so as to pass it home in to the
receptacle made to receive it, and also to rotate the measuring out discs to an extent
equal to one pennyworth of gas as herein-after fully described.
Figure 12 represents a like view as figure 11, but with the valve open, and the
parts in the positions which they respectively assume, on the automatic sale and
delivery mechanism being in action, or impelled by the action of the gas passing
through the meter, whose motion is transmitted through the drum shaft.
Figure 13 represents partly in elevation, and partly in vertical section, the said
automatic sale and delivery mechanism, for gas supply, as in figures 11 and 12.
The said view figure 13 is taken upon the dotted lines A B figure 12.
Figure 14 is a horizontal section, and top side plan of the said mechanism, taken
upon the dotted lines CD figure 11.
Figure 15 is a back sectional view of the back enclosing casing of the mechanism,
exhibiting the guide slit, the back of the pusher arm and lever, with a raised rack
upon the face of the former, around the back and front of which, the returned end of
a spring travels, on the pushing in, and pulling out of the lever.
The coin which is tendered in prepayment for certain cubic metric gas delivery, is
shown pushed fully through the jaw-like pulleys, and in a position which it assumes
on-falling.
Figure 16 represents the raised rack and spring, for preventing the lever from
being partially pushed home, and then withdrawn.
Figure 17 represents a like view, with the hooked end of the spring at the back
of the rack, while in figure 16, the said hooked end is shown engaging with the teeth
of the rack.
The same letters of reference indicate corresponding parts in figures 11 to 17, both
inclusive of the accompanying drawings.
a is a gas meter, provided with usual delivery or service pipe, and the gas passing
therethrough is controlled by the drum of the meter, which as previously described,
is impelled by the flow of gas, whose volume it measures. The chambers of the drum

page_text: are of known capacity, and its revolution, is controlled and indicated by trains of
wheel work, which register the quantity of gas upon dials placed for that purpose.
In this form of my invention, the drum is stopped, only by the shutting off of gas,
which would otherwise flow into the service pipe.
6 is a lever, fulcrumed at 63, with a box or divided like end 62, consisting of two
plates, separated from each other, to the full distance of the breadth of a penny, and
with the end thereof, enclosed by a grooved pulley b₁; so that as the coin is pushed
home, as hereinafter described, it drops between the inside periphery of the said
grooved pulley, and the centre pin upon which the lever, turns.
Thus, the lever consists of a long and short arm; the one side for working the
prepayment and gas delivery mechanism, and the other side for receiving the coin.
The view figure 11 shows the partition between the coin receptacle, and the
mechanism enclosing casing broken away, as it will be seen from the transverse
sectional plan figure 14, that the fulcrum at 3, works through the divisional wall,
which separates the said mechanism enclosing casing, from the coin receiving
compartment.
6 is a loose pulley, turning upon a fixed axis 68, secured within the coin receptacle
casing as, of the front casing at; and upon the pulleys, and 6, the coin c is
dropped, through the coin slit a, when the pusher arm and lever have been pulled
back. The coin slit a', has a guide spout a³, for conducting the said coin above the
space between the rollers.
The coin is pressed home or between the pulleys, by the pusher arm d³ of the
lever d, which is fulcrumed upon a pin centre d³ at its lower end.
The forward end d' of the pusher arm d², has a raised rack upon one side,
standing out from the face of the said end, as best seen in the back elevation figure 15,
and in the sectional views figures 16 and 17. This rack is plain upon its top edge,
and toothed upon its under edge, with the teeth raking outwardly.
d' is a flat spring, with a hooked or returned end d'; and which said end moves
alternately upon the plain top side, and the racked underside.
Thus, on the pushing in of the pusher arm d², and the carrying with it, of the
rack d³, the teeth of the rack are made to wipe over the returned outer end d', of
the spring ; and should the lever d be only partially pressed home, then it is
prevented from being again pulled out, by the said end of the spring confronting
the reverse way of the teeth, which thereby prevents the same being moved, until the
rack teeth have completely wiped or travelled over, the end d', of the spring as
aforesaid; by this means, any attempt to fraudently obtain gas, other than in a
prescribed manner, is prevented. Further, the pulling out of the lever, straightens
out the spring, and makes the hooked end d, travel up the plain top edge, and
return to its normal position, in front of the lower end of the rack.
of
Thus, after the coin c, has been fully pressed home, by the edge of the part d*,
the pusher arm d³, impressing itself upon the rim of the coin, the whole of the teeth
of the rack, have been made to travel, and wipe over the end d', of the spring,
when the spring reaching the top end of the rack, slightly straightens out, and brings
the said end d', upon the curved part; so that on the lever d being pulled out, the
spring then further straightens out, and travels back on the plain top edge, in the
direction as indicated by the arrow, and on arriving at the bottom lower end, then
the spring shortens again, so as to bring its end, that it shall be able to act upon the
rack teeth, for the next forward movement of the lever.
It will be seen that the pulling out, and pushing in of the lever, for the
uncovering of the coin slit, which is done by the top part of the lever, and the
pressing home of the coin, makes the end of the spring, travel around both the plain
and serrated parts of the standing-up rack.
It will also be observed, that the pulling out of the lever is necessary, for the
uncovering of the coin slit a².
The long arm be, of the lever b, has a catch or tooth e, upon its underside, which is
made to engage with notches h², o³, of a penny measuring out disc h, and a shilling
measuring out disc o, as best seen in the sectional plan, figure 14, and in the vertical
B

page_text: section figure 13; and fast upon the outside face of the penny measuring out disc h,
is a ratchet wheel g; and with the teeth of this ratchet wheel, the hooked end f³, of
the swinging pawl f, connected to the arm 66, of the lever b, engages. The hanging
pawl f, has a flat spring f at its back, which on being moved upwardly, takes the
hooked end into position with the teeth, but on its descent, pressure being relieved,
it falls away from the teeth, by being hung out of the centre of motion.
The lever b, which is counterpoised by the weight of the valve and other auxiliary
moving parts, disposed above it, as herein-after described, carries a forked upright 67,
with fixed studs or pins 68, near its upper ends, which work within upright longitudinal
slots 1ª of opposite slides 1, which are worked in an upward direction, by the short
end 2 of a weighted arm 2, fulcrumed at 2b, having upon its extreme outer end,
a weight 2, which is limited in its motion, by a bracket stop 2.
The slides 1, which are situated on the two opposite sides of the chamber or
casings, of the mercurial slide s, have short slots 1b, in their upper ends, wherein
opposite pins 3* carried upon the lower ends of upper slides 3, rest. These upper
slides 3, are connected by pins 3b, to the movable valve w, by a valve stalk w³, the
cognate parts of which said valve stem and valvo, will be fully described later on
in this Specification.
The extreme outer end of the arm 66, of the lever b, carries an upwardly directed
and jointed arm 6º, with a long slot 610, at its upper end, wherein a pin 2°, carried
by the weighted arm 2, works.
The bottom 6, of this slot, is for the purpose of reclosing the valve, on the pulley
jaws being opened to their fullest extent; that is, when the coin has got half way
through. So that should a coin, or any other object be designedly placed between
the jaws, for the purpose of holding them open, or the lever down, then the object
is frustrated, as the gas is thereby cut off, by the closing of the valve.
Thus, the introduction of a penny through the coin slit a², and on the same being
directed to the top of the short end of the lever, between the grooved pulleys, the
pressing inwards of the coin, depresses the short end 2, of the lever b, and raises the
long arm 66, and the tooth or catch e, from out of the notches ³, o³, of the gas
measuring out discs h, o, raises the forked upright 6', and its pin 68, above the lower
end of the slot 1° of the slides 1, thereby freeing the said slides from any downward
pressure, thus allowing the said slides to rise, and press upwards the valve w, through
the intervention of its stalk w², and the upper slide 3.
The rising or upward movement, is effected by the pin 2' on the end of the short
arm 2", of the weighted arm 2 rising, by the falling of the weighted end 2° on the same
being free to move.
Thus, the bottoms of the grooves 1ª follow the upward movements of the pins 68,
thus allowing the lower slides 1, to rise by the falling of the weighted end of the arm 2,
consequent upon the same being weighted and fulcrumed as represented; and which
said upward movement of the slide, raises the, valve, by the rising of the upper slides 3,
which are connected with the valve stalk.
The partial rising of the arm 68, raises the upwardly directed arm 6°; and the falling
of the weighted arm 2, brings its pin 2°, to the bottom of the slot 610 of the said
arm ; so that the further pressing inwards of the coin, and the consequent changing
of the distance between the grooved pulleys, further depresses the short arm b³, of the
--lever b, and raises the long arm 6, of the said lever, and thereby still further pressing
upwards, the upright arm 6, and raising the weighted arm 2, into a neutral position,
which thus allows the valve and valve stem, and upper slide 3 to fall, and shutting off
gas as represented in figure 11.
The raising of the long arm 6 of the lever b, raises the swinging pawlf, and makes
its hooked end engage with the teeth of the ratchet wheel g, and moving the said
ratchet wheel round to an extent of six teeth, which is an equivalent to one twelfth
revolution of the penny measuring out disc, and 144th of the shilling measuring out
disc.
The ratchet wheel g, and penny measuring out disc h, are tight upon an arbor i
whose outer end, is reduced, and carries the penny indicating finger, whose

page_text: rotation is made, in front of the dial ; so that, the said wheels, and arbor, with finger
at its end, move together, and so does also a rear part the said arbor, with a
pinion n, fixed upon it, which engages with a toothed wheel p³, best seen in the plan,
figure 14, for communicating motion to the shilling finger p, mounted upon the sleeve
end of a toothed wheel p².
The shilling measuring out disc o, runs free upon the rear part it, of the said spindle i,
and a reduced motion thereto is communicated, through the same train of wheels that
communicate a like motion to the shilling finger axis. Thus, motion to the said disc o,
and its finger p, is transmitted from the pinion n, through the wheel p', to the
spindle p, which has fast upon it, pinions p³, 16, of like diameters. The pinion p³
communicates motion to the shilling finger wheel p², while the pinion po, communicates
a like motion to the shilling measuring out disc o, and which motion is reduced in
manner as aforesaid; so as to make the said finger and disc, rotate only at a speed
of 144th, that of the penny measuring out disc, and finger h, ³.
Working loosely upon the arbor i, is a tangential meter wheel 9, driven from a
worm m², of a meter axis m; and which said axis receives its motion direct from
the meter drum.
Disposed between the inner end of the sleeve q², of the meter wheel 9, and the
ratchet wheel g, is a friction clutch g², by means of which, motion from the meter,
is transmitted to the penny, and shilling measuring out discs, for taking them
back through the measured distances, which they have been moved, aforesaid.
The clutch consists of a dished-disc of metal, with inwardly directed slit
edges.
The function of the clutch, is to create sufficient binding power, between the face
of the ratchet wheel g, and the meter wheely, that after the measuring out discs have
been advanced measured distances, equivalent to the amount of gas paid for, then the
measuring out discs and driven wheels of the meter part move together, at a rate
proportional to the drum's motion.
Thus, the rising of the swinging pawl f, pulls round the ratchet wheel, and
measuring out disc, leaving the meter wheel g, which is in gear with the worm m³,
stationary, consequent upon it being unable to rotate, other than in the direction
of the meter drum; and after the said ratchet has been moved to a measured
distance, it rerotates, or moves backward, by the clutch creating sufficient friction
between the wheels as aforesaid, as to make the whole move together, as if they were
rigid upon one shaft.
The mercurial slide s, for making a sound joint, for preventing the escape of gas, on
the working of the valve, is as follows.
is an outer cylindrical casing, open at top, and closed at bottom, with slots
through its opposite sides, wherethrough pins 3b, pass, in connecting the slides 3,
to the valve stalk carrier w³, to the lower end of which, the valve stalk w³, is fixedly
connected.
The valve stalk passes through an inner tube or sleeve w¹, whose upper end carries
a dished seat to, coming within the inside of the valve w, which surmounts its
stalk w. t is the valve casing, the base thereof, wherethrough gas from the outlet
pipe u, connected with the meter, passes; so that the gas, when the valve is open, as
in figure 13, passes in the directions, as indicated by the arrow, to the service
pipe v.
The action of the machine is as follows―
The coin tendered in prepayment for gas required to be consumed, is dropped into
the coin slit a, when the lever d is fully pulled back, and in dropping through, it falls
upon and between the rollers, and also between the sides of the divided short end 62
of the lever. When in this position, as in figure 11, the lever d is moved inwardly
as indicated in the said figure 11, with the presented edge d', of the pusher arm d²
pressing forcibly upon the upper edge of the coin, which on the lever being further
pressed forward, the pressure thus exerted, forces down the short arm 62, turns the
lever b upon its fulcrum raises the long arm 66, and takes the catch or tooth e,
from out of the notches h³, o³, of the measuring out discs, raises the forked upright 67,

page_text: and its fixed studs or pins 68, freeing the slides 1 from downward pressure, which are
now made to rise, by the weighted arm 2, whose inner end 2ª is connected to the said
slides 1, by studs 2f; and which upward movement of the said slides, raises the
upper slides 3, through the pins 3*, working in the short slots 1°, and slightly raises
the valve stalk, and with it, the valve; this is the first movement, and it may be
here observed, that the falling of the weighted arm 2, has caused the pin 2° to
fall down the slot 610, to nearly the end 6. The continued and further movement
of the lever, brings the penny halfway through, or midway between the rollers b¹,
and which position creates a closing of the valve, by the continued upward movement
of the long arm 66, of the arm 6, causing the bottom ", of the slot 610 of the
upwardly directed arm 69, to raise the long arm of the weighted lever 2, thereby
lowering the valve, by depressing the slides 1, whose opposite slots 1" work over the
pins, and drawn down the upper slides 3, and with them the valve stalk and valve,
so as to close the valve as in figure 11, and cut off gas.
'
During the partial opening of the valve, and its closing as aforesaid, the raising of
the arm b, of the lever b, has raised the swinging pawl f, and made its hooked lower
end engage with the teeth of the ratchet wheel g, and pull the ratchet wheel round to
the extent of six teeth, and the measuring out disc h, through a distance of one
twelfth of a revolution, and the shilling measuring out disc, through a distance of
144th of a revolution, bringing the respective notches 2, o³, into the positions as
indicated at figure 12.
The motion of both penny and shilling measuring out discs, are communicated and
indicated by the fingers, p; and during the time that the said discs are moved
forward to a measured distance, the resistance offered by the clutch g³, is less than the
force applied; so that the clutch remains quiescent with the meter wheel q; but on.
the coin c being fully pushed home, through the rollers, it drops by its own weight,
into the coin receptacle k, made to receive it.
The lever being now free of the coin, the weight pressure of the valve, and the
parts connected with it, causes the long arm of the lever, to be lowered or pressed
downwards (with the short end 6 raised) until the point of the catch or tooth e, rests
upon the peripheries of both penny and shilling measuring out discs, as indicated
in figure 12; and in consequence of the slides being free of downward pressure
of the studs 68, they rise by the falling of the weighted arm 2, thereby raising the
valve, through the intervention of the upper slides 3, connected with the lower slides 1,
and so allow gas to flow from the meter, to the delivery pipe v, until the notches /*
and o, of the penny and shilling measuring out discs h and o, respectively, become
coincident, and under the point of the tooth or catch e, when it falls into both
notches, allows the long arm to be lowered, which pulls down the forked
upright, and its pins 6, pulls down the slides 1, by coming at the bottom of
the slots 1º, raise the weighted lever into a horizontal position, lowers and closes
the valve, through the intervention of the upper slide 3, connected with the lower
slide, and puts the parts into their normal positions as represented in figure 11.
The parts are prevented from falling too rapidly, by the fly 4, consisting of
radiating vanes, turning upon a fulcrum centre 4, with a pinion 4 upon it,
which gears with a toothed sector 5, fulcrumed at 5, and connected by pins 3°,
to the upper slides 3, by which means, the falling or lowering of the parts are
only slowly allowed to move into their pre-determined positions.
Figure 18 represents in front elevation, with some of the parts broken off, and
in vertical section, a portion of a gas meter, provided with automatic sale, delivery,
and check mechanism, constructed and arranged according to another form of my said
invention; and the parts of which said mechanism, are shown in the positions which
they assume, on a penny being first tendered in payment for a predeterinined quantity
of gas required to be delivered.
It will be seen that the said figure 18, that the coin which is marked has been
dropped through the coin-slit, and in resting between the grooved peripheries of two 5
pulleys, disposed at a distance apart.
Figure 19 represents a like elevation and section, as that of figure 18, but with the

page_text: parts of the said automatic sale and delivery check mechanism, in the positions which
they respectively assume, after the coin has been forced partially between the grooved.
pulleys, as hereinafter described; and which said opening out of the pulleys, to the
extent of the coin's diameter, is the limit of movement which the said parts make.
Figure 20 shows a like view, as that of figures 18 and 19, but with the respective
parts of the automatic sale and delivery mechanism, in the positions, which they
assume, after the coin, tendered in prepayment of gas to be supplied, has passed
through the machine, and been conveyed into a receptacle made to receive it.
It will be observed, that the machine is now delivering out, by the back rotation of
gas measuring out wheels, and that the mechanism only commences to deliver or act,
after the coin has been fully passed through the machine.
Figure 21 is a transverse vertical section of the said mechanism, and enclosing
casing, upon the dotted lines A B figure 18, and figure 2, is a transverse vertical
section on the dotted lines C D figure 18.
Figure 23 is a back elevation of the coin lever, and partition of an enclosing casing,
where-through the spout of the coin-slit passes. This view is shown specially for
the purpose of representing the back of the pushing in lever; so that a coin or the
lever, must be pushed absolutely home, before it can again be withdrawn, as the pawl,
which is a spring arm, working upon the rack upon one side, and a plain part on the
other side, has to travel from front to back, and in a circular manner, in order that
the lever may be pushed in, for pressing the coins home, and pulled out, in order to
introduce others into the slit.
Figure 25 represents the box rack in horizontal section, and figure 24 represents
the same in vertical section, on the dotted lines E F figure 23. Figure 26 represents
an elevation and section of the spring pawl.
Figures 27, 28, 29 and 30, represent some of the main parts of the mechanism,
separately.
The same letters of reference, indicate corresponding parts in figures 18 to 26 both
inclusive of the drawings.
a is the gas meter, a³ is a coin slit, and as is the guide of the spout, seen in the back
elevation figure 23, and through which slit, and down the said spout, the coin falls
and rests upon the short arm of a coin lever b, whose long arm 6º, is weighted or
counterpoised. The said lever is best shown in back elevation in figure 23. The
short arm of this said lever, which is made up of sides, with a division or space between
them, carries a grooved pulley ; and situated at a distance from this said pulley, is
a second grooved pulley, turning upon a pin fitted within the fixed framing. Thus,
the pulley, may be spoken of, as a fixed pulley, and the pulley 6, as a movable
pulley, and between these said pulleys, the coin deposited, in prepayment of gas to be
consumed, rests, before it is pressed home, which "act," measures out its worth of gas,
upon a measuring out wheel as herein after described.
The coin lever b, which is mounted on, and works with an axis 63, has made fast
upon it, the inner end of a slotted arm; and within the slot, of which, a fixed
pin f, carried by the main lever f³, works; and which said main lever turns upon an
end fulcrum, and with the other end provided with a swinging pawl f, whose lower
end 3, is hooked inwardly, and engages with the teeth of a ratchet wheel carried
upon the front face of a penny measuring out disc h, whose periphery is provided with
a notch or inclined gap, wherein the tooth or catch e, engages. This tooth or catch
is carried upon the underside of the long arm e³, of a weighted lever e², whose fulcrum
centre, is the cross axis of the coin lever b, and slotted arm x, x², and jointedly
connected to the long arm of the said lever e³, is a forked upright link e*, jointed at
its upper end by pins e, which connect it to the valve stalk to, by means of which,
the valve is opened and closed.
The pin which is carried by the main lever ƒ³, is made adjustable, and fixed
within the slot, by a screw nut f7; so that by increasing the distance between the
main lever fulcrum f³, and the pin which controls the motion of a slotted arm,
varying adjustments may be obtained.
Thus, if the pin f* be placed in the slot, nearer to the fulcrum centre f³, then the

page_text: throw of the slotted arm a will be less, and the movement required to be made, by the
rocking coin lever b, will also be reduced.
It will be seen that the pushing inwards of a coin c, between the movable and
adjustable rollers 6, 6, that the short end 2 of the rocking coin lever b, is lowered,
which on the turning of its fulcrum centre 63, gives the same motion to the slotted
arm; and in consequence of the pin f, being carried by the main lever f³, whose
fulcrum centre is at f, the said pin moves up the slot, and consequent thereby, the
main lever long arm f³, and swinging pawl f, are depressed, taking the hooked end f²,
of the said swinging pawl, at the back of the half-round snug 14, of a crank lever 1,
fulcrumed at 1b, and having the end 1°, weighted, and being kept in a determinate
position, by a fixed stud or stop 1ª.
The hooked end f2, of the swinging pawl f, has a pin f8, which traverses the
convex of the snug 1, and then on the upward movement, it comes on the front of
the snug, and passes upon the inner and flat side of the said snug, thereby keeping
the hooked end always up to the teeth of the ratchet wheel, during the time that the
ratchet wheel is being advanced, and on the further rising of the said swinging pawl,
the swell, upon its inner edge, comes against the axis of the shilling finger
transmitting wheel p, and pulls the hooked end f2 from the teeth of the said ratchet
wheel.
Thus, by the oscillation of the main lever f, f³, the pin f is made to travel around
a snug, which when it is upon its front side, keeps the hooked end of the pawl up to
its work, which is then drawn away, by the swell as aforesaid, as it will be observed,
that the down movement prevents the hooked end from wiping over the teeth, as is
common with ordinary pawls; and further, the said pawl is pressed inwards by a flat
spring f10.
The downward movement of the main lever, distends a coiled spring 2, disposed near
its joint end, and the top of the enclosing casing.
The rear end of the main lever f³, carries a rack 3, which engages with a pinion 3,
on an axis 3b, which has fast upon it, a toothed wheel 3°, which gears with a pinion 4,
whose axis carries a fly 4, which by its rapid rotation, encounters the resistance of the
air, and so prevents the return of the moving parts too precipitously.
d is a lever, fulcrumed at d³, for pushing inwards a coin pusher d, whose inner
end d, impinges upon the edge of a coin. The upright inner edge of the said lever d,
covers up the coin slit a³, and prevents the introduction of moneys, until the pusher
arm, has been wholly withdrawn, so as to admit of the coin tendered in payment of
the quantity of gas required, to be properly directed to the top of the grooved pulleys
as aforesaid.
The back of the pusher arm d³, is provided with a rack and pawl device, for
preventing the lever from being pulled back, or the pusher arm withdrawn, until the
coin has been pushed or forced fully home; that is, the lever and the pusher arm must
make their allotted inward motion, before they can be withdrawn, or pulled back, and
which is done, by making the spring pawl, which is nothing more than a catch, traverse
both the toothed and plain side of a rack, in a circular manner.
d is a box rack, with teeth d³, upon its one side, and plain upon its inner side do,
as best seen in figures 23, 24 and 25.
The top of the said inner side is inclined inwards. do is a spring pawl, with
returned or hooked end d', and when in its acting position, its tendency is to spring
outwards, but not sufficiently far to interfere with it, properly wiping over the teeth
of the rack. Thus, when the lever d is pushed inwards, for the pressing home of the
coin, the arm d², causes the teeth ds to be moved past and under the returned end d',
of the spring pawl d', until it arrives past the top tooth, when it falls and springs
inwards to a little inward of the incline do, when the outward movement of the lever
now brings the pawl at the back do, and in consequence of it travelling up the
incline do, it has been bent inwards, and on arriving at the gap d', it resumes its
normal condition, and springs outwards, with its underside resting at the bottom of
the incline of the bottom tooth; so that by the pushing in, and drawing out of the
lever, the hooked end is brought, and made to travel up the inclines of the teeth, click

page_text: over the shoulders, and as each incline bends the pawl outwards, so that on coming at
the top of the incline of the top tooth, it springs inwardly through the gap d¹¹, to the
commencement of the incline at the back, and which incline on being drawn forward,
with the rack, bends the spring pawl inwards, until it has again come to the gap d,
and completed its circular movement. The cross section of the end d', of the spring
pawl de, is shown at figure 26.
It will be observed in referring back to the lever e², of the tooth or catch e, and by
whose upward motion, the valve stalk w, is raised and lowered, that it is simply an
arm, loosely turning upon the axis b³, as a joint centre; and is raised simply by tho
incline of the notches A and o³ the latter hereinafter described.
On the advance movement made by the gas measuring out discs and o, consequent
upon the pulling round of the ratchet wheel, the tooth or catch e, is removed from
the notches, on to the peripheries of the discs respectively, and on the said discs
moving backward to their allotted cubic metric distances, the said tooth or catch falls
again within the coincident notches, lowers the valve stalk by the pulling down of the
upright e, and so shuts off the gas, or closes the valve, which is carried at the summit
of the stalk.
is
The penny measuring out disc h, which has upon its face, the ratchet wheel
tight upon
the arbor i, whose outer end 2, is reduced, and carries the penny indicating
finger, whose rotation is made in front of the dial; so that the said wheels g, h,
and arbor with finger at its end, move together, and so does the rear part of the said
arbor, which has a pinion n fast upon it, which engages with a toothed wheel p³, as.
best seen in the plans, figures 21 and 22, which communicates the motion of the finger
axis to the shilling disc o, loosely running upon the axis it, and which shilling disc
has a toothed wheel o² fast upon its back; and which said motion to the shilling dise
and its finger p is communicated from the pinion n, on penny disc arbor, to a toothed
wheel p and spindle p*, carrying pinions p³ p²..
The pinion p transmits the motion of the spindle p, to the wheel o, o³, at the back
of the shilling disc o, and so gives to the shilling disc 144th of a revolution to every
one twelfth of a revolution made by the penny disc h.
Motion to the shilling finger p, is made through the large loosely mounted toothed
wheel p², whose outer end has a sleeve, upon which the said finger is carried.
Working loosely upon the arbor i is a tangential or toothed meter wheel q, driven
from a worm m², of a meter axis m, and which said axis receives its motion direct from
the meter drum.
Disposed between the inner end of the sleeve 9 of the meter wheel g, and the
ratchet wheel is a friction clutch g³, by means of which, motion from the meter is
transmitted to the penny and shilling measuring out discs, for taking them back
through their measured out, and allotted distances, through which they have been
moved forward, and which distances represent a fixed quantity of gas, which is allowed
to be consumed, in exchange for the coin passed through the machine.
The clutch consists of a dished disc of metal, with radially directed slit edges, so as
to create sufficient binding, for the moving together, or in common with another, the
parts in juxta position to its two opposite faces.
Thus the function of the clutch is to create sufficient binding power between the
face of the ratchet wheel g, and the meter wheel q, that after the measuring out discs
have been advanced measured distances, equivalent to the amount of gas paid for, then
the said discs, and driven wheels of the meter part, move together proportional to the
drum's motion.
Thus, the pulling up of the swinging pawl f, and the advancing of the ratchet
wheel g, through a measured distance, the meter wheel q remains quiescent, as it
cannot rotate in a reverse direction, to the motion of the meter drum, as it is pulling
against the worm m²; so that the friction of the clutch, makes fast the measuring out
part of the mechanism, when it is to move, in the same direction as, and with the drum
of the meter.
The action of the said automatic sale and delivery gas mechanism is as follows:-
On a penny being passed through the coin slit a², when the lever d, and pusher

page_text: arm d is pulled back, the coin falls by its own weight into position between fixed and
movable rollers bb; and when in this position as represented in figures 18 and 23,
the lever d is forcibly pushed inwardly, when the extreme end d of the pusher arm d²,
impinges upon the rim of the coin, and forces the said coin between the rollers 61, 64,
which act, or forcing inwards of the said coin, depresses the short arm 62 and roller b',
of the coin lever b, raises the weighted end 66, and also turns its axis band with it
the slotted arm, whereby through the intervention of the pin f, working within the
slot, that the main lever f³ is lowered upon its fulcrum centre f depressing the
swinging pawl, and with the pin f at the hooked end f, made to pass around
the outside of the snug 12 at the top of the arm 1 of the weighted cranked lever,
which is fulcrumed at 1b, and on the said pin f8 arriving at the bottom of the said
snug, the pressure of the spring f10, takes the point of the hooked end as aforesaid,
into a tooth of the ratchet wheel g, and when in this position, the coin having been
forcibly pressed completely home, or inwardly from between the rollers, the spring 2,
which became distended, on the lowering of the main lever, now contracts itself,
drawing upwards the main lever f³, and with it the swinging pawl f, which being
engaged with the tooth of the ratchet wheel g, advances the ratchet wheel to an extent
of six teeth, and with it, the penny measuring out disc , and shilling measuring out
disc o, through a distance of the one, equal to one twelfth of a revolution, and with
the other through 144th of a revolution.
The upward movement of the hooked end f, causes the pin f8, to travel up the
inside of the snug 12, and by the crank lever being weighted, the tooth thereby is
constantly kept up to the face of the ratchet wheel, until it arrives above the top of the
snug, when it is drawn from it, by the swell, being drawn against the axis p', which
brings the pin p8, to the top of the front side of the said snug, ready for the next
downward movement.
The advancing forward of the penny measuring out disc, and the shilling disc,
causes the point of the tooth or catch e, which acts in common to both discs, to be
withdrawn up the inclines of the notches or depressions h³, o³, to the peripheries or
edges of the discs, thus raising the tooth or catch lever e³ upon its fulcrum or hanging
centre, and in consequence of its outer end being raised from a lower, to a higher
level, by the forcible displacement of the tooth from the notches, the forked upright
link e, is consequently also raised, and the valve, surmounting the valve stalk wis
opened, thereby admitting gas to flow from the meter pipe, to the service, until the
notches of the measuring out discs have returned to their normal and coincident
positions, and opposite the tooth e.
The parts which have resumed their normal positions, as in figure 18, have been
prevented from passing back too precipitously, by the rack 3 engaging with the
pinion 3, and through its axis 3b, to the toothed wheel 3º, which rotates the pinion 4b,
upon whose axis the fly 4 is fixedly secured, and thereby rotated, and whose motion is
regulated, by the resistance of the air.
The advance movement of the ratchet wheel as aforesaid, turns the finger ³, through
a graduated distance in front of the dial, while the shilling finger p, and disc o, are
turned through corresponding reduced distances, by the pinion n, engaging with the
toothed wheel p³, to the spindle p*, and from thence through the pinions p³, p, to
the toothed wheel o² of the disc o, and the toothed wheel p², of the sleeve of
the finger p. The advance movements of the discs being made in a direction contrary
to the motion of the meter drum, and as the force applied is greater than the pressure
of the clutch, then the ratchet wheel g, and measuring out wheel h, after having been
moved through their allotted distances, the meter drum now moving, communicates its
motion to the train of wheels, and through the clutch g³, to the measuring out wheels,
carrying the said wheels back to their normal positions; and until the catch or tooth e,
of the catch lever e³, comes opposite the notches h², o³, when the said catch moving
slowly, down the inclines, gradually shuts off the gas, by the lowering of the lever,
upright link e, valve stalk w³, and valve, thereby cutting off communication between
the pipe leading from the meter, to the service pipe.
Figure 31 shows a modified form of the said arrangements, from figures 18 to 22.

page_text: a is the meter, a³ the coin slit, and at the front casing, wherein the main portion of
the automatic sale and delivery mechanism is enclosed. a is the back compartment,
wherein the coin lever b works of which 6 is the short arm, carrying a grooved
pulley b', and which lever turns with its fulcrum 63, whose front end carries an arm f³,
with its outer end provided with a swinging pawl f, whose lower hooked end f³,
engages with the teeth of a ratchet wheel g, upon the front face of a measuring out
disc h, with a notch * on its periphery.
The swinging pawlf is pressed up to the teeth of the ratchet wheel, by a spring 10,
while connection between the meter going wheels is made by the clutch g¹ and motion
received thereby, through the wheel q, which is driven from the worm m² of an axis m,
with which the axis of the meter is in direct communication. e is the tooth or catch,
which engages with both penny and shilling measuring out discs, and which is carried
by a weighted and hanging lever e³, fulcrumed and turning upon the pin b³.
wo is a valve, worked by a valve stalk w jointedly connected at its lower end to the
lever ; and which stalk passes through a packing us, situated within a gland u°, on
the underside of the outlet u leading from the meter; and by the raising of which
said valve, gas is allowed to pass to the service v.
d is the lever, and d the pusher arm, whilst b is the fixed pulley.
It will be thus seen that the arrangement figure 31 is only a simplified form of
the arrangement figures 18, 19 and 20.
Thus, on placing a penny through the slit a³, it drops upon the grooved
pulleys b¹, 6, and on the pressing inwards of the pusher arm d of the lever d, the
coin is forced home between the rollers, which depresses the short arm 6 of the lever b,
turns its joint centre 63, and with it raises the lever f³, and pawl f, whose hooked end f
engages with the teeth of the ratchet wheel, pulling it round to the extent of six teeth,
and also advances, or winds up the penny and shilling measuring out discs h and o,
which causes the point of the tooth or catch e, to travel up the inclines of the
notches h², o, (the latter not shown) until the said tooth or catch rests upon the
peripheries of the said discs; which change of elevation raises the lever, valve
stalk w' and valve w, thus allowing gas to pass from the gas meter outlet U, to the
service v; and as the whole of the other parts of the automatic sale and delivery
mechanism are alike to those of figures 20 to 30, the re-rotation of the measuring
out discs, on the pennyworth of gas being consumed, brings their notches opposite the
tooth or catch e, when by the change of elevation, from the rims to the bottoms of the
notches, the valve is lowered by the falling of the valve stalk.
