Improvements in Automatic Apparatus for Delivering Liquids, both
Hot and Cold, in Exchange for Coin, and in Supplementary
Appliances to be used in connection therewith.
I, ROBERT WILLOUGHBY VINING of Ranmoor Forest Hill in the City of
London Engineer, do hereby declare the nature of this invention to be as
follows;-
My invention has reference to apparatus which will automatically mix two or
more liquids, such as an essence and water, and deliver the same in given quantities,
in exchange for one or more prescribed coins, inserted in the apparatus or it will
deliver liquids without any mixing.
My improved apparatus for the purpose of delivering spirits, wine and the like,
is mainly composed of a charge cylinder, a piston or slide in this cylinder, pipes or
passages connected to the two ends of the cylinders, and a coin operated valve,
with which the opposite ends of the said pipes or passages are connected, and
which puts the two ends of the cylinder, alternately into communication with the
main liquid supply, the other end of the cylinder, being at the same time in
communication with a delivery pipe or nozzle.
In carrying out my invention, the vessel or reservoir containing the liquid to be
supplied, can either be placed at such a height above the machine, as to ensure
sufficient pressure to move the piston or valve, as hereinafter described, or the
liquid can be given the necessary pressure by means of compressed air, or
otherwise; a pipe or passage leads from the said vessel or reservoir to the valve,
and the valve has ports or ways communicating as above explained, with the two
ends of the charge cylinder, and with the delivery pipe or nozzle. The valve is
preferably rotary, and may be arranged either to turn always in the same direction,
or in reverse directions alternately. It is actuated by the coin or coins, and this
can be conveniently effected by causing them, after being inserted through a slot,
and passing down a shoot, to come upon a plate or platform, and thereby depress a
lever, which is connected with the valve. The charge cylinder always contains on
the one or the other side of its piston, the quantity of liquid for one delivery.
The action is as follows:-When the prescribed coin or coins are inserted, the
valve is moved through the intervention of the lever, into the position which opens
communication between the liquid reservoir and the uncharged end of the cylinder;
liquid then flows into the end of the cylinder, and by its pressure moves the piston
to the other end, thereby driving the charge which is in this other end, into and
through the passage leading to the valve, through which it flows to the delivery
nozzle. What was the uncharged end of the cylinder, has now become the charged
end, and vice versa, and on the next insertion of coin, the position of the valve is
reversed, and what is now the uncharged end, received the liquid from the reservoir,
and the liquid in the charged end, is forced out to the valve, and thence to the
delivery nozzle. The two ends are thus charged and emptied alternately. The
amount of liquid can be regulated by means of set screws which limit the travel of
the piston as required.
Where I wish to deliver a liquid to be fresh mixed, (such as coffee or bovril) for
each insertion of coin, I have a chamber containing water kept hot by means of
gas or other equivalent, and which can be supplied direct from the mains, a suitable
arrangement being of course used, to limit, or even at once stop, the supply of
either water or gas.
Below the chamber or tank, I have another chamber or cylinder, but without
termed the mixing chamber and in this is a ball with a valve at the top,
niston

page_text: which communicates with a third chamber above, containing the essence. There is
also an air valve at its side, which closes by the pressure of the liquid, when in
operation, and also where more than one coin is used, it removes an obstruction in
the money slide, raised by the action of the first penny in the money slide, thus
retaining the second penny, and preventing its doing anything until the operation
of mixing is complete.
The water and mixing chambers, are connected to a valve as described before,
only that it is a three way one.
The action is as follows; the first coin raises an obstruction in the slide (on
which the second penny rests); it then falls on the lever, turns the valve, and puts
the water chamber in communication with the mixing chamber, causing the water
to flow in; it lifts the ball, opens the valve, and allows a given quantity of essence
to fall, and as soon as chamber is full, the air valve rises and removes the
obstruction in money slide, allowing the second penny to fall on the other end of
the lever, reversing the valve and causing the hot water to be shut off, at the same
time putting the mixed liquid in chamber, in communication with the delivery
nozzle, and consequently delivering it into a cup or other receptacle.
If I wish to deliver a liquid that does not require mixing, and a charge of which
is sold for a penny I have two cylinders, but only fitted with the ball and air
valve, or I can do without either of the latter, by carrying pipe from the top of
each chamber to the top of the vessel containing the liquid above; in this case I
use a four way valve as before described, with a rotary double port action; two
are connected with the cylinder, one with the tank above, and the other with the
delivery nozzle.
When charged one cylinder is always full, ready for delivery, and on insertion of
a coin, this full cylinder, by the quarter rotation of the valve actuated by the coin
falling on the lever, at once begins to empty through the delivery nozzle, and at the
same time, and by the same action, the other cylinder is filling ready for the
insertion of the next coin to empty it by the reversal of the lever, and so on
emptying and filling as before described alternately.
In case the machine has to be made to work with a small coin, such as a three-
penny bit, or sixpence, I use a small supplementary cylinder to do the work or else
a small clockwork or escapement with weight; by these means the machine can be
made to work automatically with any coin.

Improvements in Automatic Apparatus for Delivering Liquids, both 4
Hot and Cold, in Exchange for Coin, and in Supplementary
Appliances to be used in connection therewith.
1, ROBERT WILLOUGHBY VINING, of Ranmoor, Forest Hill, London 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 4
statement:
This invention relates to prepayment automatic machines or apparatus for the
delivery of liquids, both hot and cold, in exchange for coin or coins, or equivalent.
Figure 1 of the accompanying drawings represents, in vertical section, the upper
portion of a prepayment automatic machine or apparatus, for the delivery of a
liquid or liquids in exchange for coins or equivalent.
The said apparatus consists essentially of a pillar erection, having contained
within it, and at its upper part, a supply tank or reservoir, communicating-by.a

page_text: tube or passage, to two measuring vessels, or closed topped cylinders, which are
alternately filled, or allowed to be filled and emptied, by the aid of a coin-operated
valve of a four way cock, which communicates with supply pipe, delivery pipe and
measure passages respectively. Thus, the insertion of a coin through a coin slot,
operates the said valve, and makes the passages of the same, become alternately
coincident with the ports of the cock, hence the intermittent filling and emptying of
the measuring vessels, or closed topped cylinders.
Figure 2 represents the lower or base portion of the machine or apparatus,
showing the connection of the coin beam with the rocking beam, made fast at the
inwardly directed end of the stalk which actuates the valve.
Figure 3 represents a vertical section of the lower part of the main liquid supply
tank or reservoir, and the measuring vessels or cylinders, with the passages leading
from, and communicating with the said supply tank and vessels, and which view is
taken upon the dotted lines A B. Figure 1, looking from right to left.
Figure 4 is a back elevation of the four way supply cock, and the rock lever
made fast upon the end of its valve stalk.
Figure 5 is a back elevation of the said four way cock, with the valve removed,
showing the passages of the supply, and delivery pipes, and also the passages
leading to the measuring vessels.
Figure 6 is an inside elevation of the valve, showing its channelled formation.
Figure 7 is a plan of the valve stalk, and Figure 8 is a front elevation of the
coin slot, which is fitted or provided with a jointed closing plate, under the direct
control of a float within the main liquid supply tank, which is preferably outside
jacketed with a non-heat-conducting material, such as felt or other like material.
By enclosing the tank proper within a non-heat-conducting material, the liquids
are kept cool, which is a considerable advantage.
Figure 9 represents a vertical section, through that part of the apparatus located
near the bend of the throat of the coin slot, and looking from left to right, and
from a position beyond the rock lever of the valve stalk, which is directed
horizontally, whilst the valve itself and cock, or those parts with which liquid
comes in contact, are preferably made of vulcanite.
It will be seen from the said Figure 9, that the passing of pennies or other coins
down the coin slot, gives an alternate tip to a device, placed at junction of two
branched passages, which lead to boxes situated at the ends of a rocking coin
beam, so that as the coin is introduced into one or other of the boxes, the gravitating
weight of the same causes one end to be depressed, and the rocking beam turned, so
as to bring the coin box at the other end of the said beam under the other branch
of the two-way coin shoot.
Figure 10 represents the rocking coin beam and its cognate parts.
e,
The same letters of reference indicate corresponding parts in Figures 1 to 10.
a is a pillar casing, having a hinged top or covering a², and a foot or base a³, and
located or disposed within the upper part of the said enclosing casing is a main
liquid supply tank b, open at top at b, and provided at bottom with a well b³,
having leading from it, a vertical outlet pipe c, downwardly terminating in the
body part of a cock d, having directed horizontally through its middle a stalk
carrying at one end, a channel faced valve f, and at the other end a rock lever g,
having suspended from its ends, flexible cords or chains h, whose lower ends are
connected to a rocking coin beam i, pivoted at ³, and carrying upon the top side of
its two outer ends, coin boxes j,, with counterpoised or balanced bottoms j, j³,
which are adapted to strike against pins k, k³, disposed near the open mouths of the
branches,, of the coin race 4, whose lower end 1, dips into the cash box .
The main supply tank b which is fitted with a float m, having a cord m²,
connected at n², to a jointed slot-closing plate n, pivoted at n', and adapted to close
the entrance to the throat o, of a coin slot o, has a jacket a', of felt or other like
non-heat-conducting material, for the purpose of keeping the contents of the tank
cool, whilst the cock d, is of a four-way construction, (see Figures 1, 3 and 5) with
the passages through the same in direct communication with the supply pipe c, the

page_text: delivery pipe p, and horizontal passage 9, 9³, which latter lead from upright
measuring vessels, or closed topped cylinders r, ³, disposed on the two opposite
sides of the said supply pipe, and which vessels become alternately filled and
emptied, on the rocking of the coin operated lever, through the gravitating effect
of a coin introduced in prepayment for the liquid, such as lemonade or the like, to
be delivered.
Directed upwardly from the middles of the lids, of the said vessels, are air
escape tubes 3, s, proceeding upwards to the height of the top of the supply tank,
and by means of which, air confined within the passages, after each alternate
working, is allowed to escape, and the liquid from the supply, to flow, without
interruption, into the measuring vessels, and passages leading to or from them.
The cock d, has a flat and annular facing d', against which the acting face, of
the channelled valve f, takes its bearing, and which channels are marked ƒ³, f*
(see Figure 6), and on the same being brought alternately (as hereinafter described)
in front of the four-way cock passages, communication is made between supply and
measuring vessel passages, and delivery passage, in such order, that when the valve
is in one position, one of the channels of the valve couples or connects the supply
pipe with the right hand measuring vessel passage for filling, whilst the other
channel, makes communication between the delivery pipe, and the passage of the
left hand measuring vessel, which is required to be emptied (see Figure 3).
By now turning the valve a quarter of a rotation, after the said left-hand vessel
has been emptied, the passages or ports of the cock are so coupled, or com-
munication between them made, that an alternate emptying and re-filling is
performed.
The valve which is carried at the end of its stalk e, is kept in position by a
screw pin f, and a lock nut f, and up to its seat, by the pressure of the liquid
contained within the passages of the cock, passing to a back chamber f, through
an inlet passage, and which chamber is made by an enclosing covering f'.
Situated below the outlet of the delivery passage, is an inclined spout t, with a
catch neck t, and a delivery end t³, facing and standing a short distance away
from the box entrance t, of a passage, leading to the barrel to, of a delivery
nozzle t', whose body part is directed through the walls of the outer pillar
casing a.
By having an intervening space between the end t³ of the spout t, and the box {*
of the passage to the delivery nozzle, dribblings, after each passage of liquid, are
prevented, by the same dropping between the said space into a drip tank made to
receive them.
The said parts herein before enumerated are supported upon suitable brackets and.
affixing plates, mounted within the interior of the casing.
The throat o, of the coin slot o, leads to a casing os, at the junction of branched
coin shoots o, o, with their terminations 06, 0', coming immediately above the
boxes j³, at the ends of the rocking coin beam i, respectively, when the said beam is
elevated or inclined. Working within the junction casing o³, of the coin shoots,
races or passages, is a tip », jointed at ³, and having pallets or rests v³, v², and
upright divisions v. Coins are, by this device, passed alternately down the shoots,
by which means, the rock is given to the rocking coin beam, and through the
intervention or medium of which, the valve of the four-way cock is operated, so as
to alternately change the positions of the channels of the said valve, relatively to
the ways or passages of the cock.
Thus, assuming the tip to be in the position as represented in Figure 9, by the
passing of a coin down the coin slot, and the sliding of the same into the chamber,
and upon the pallet v³, the said tip is then turned from left to right, and the coin
passed down the shoot of, 0%, and deposited in the box ;, of the rocking beam i.
The end of the beam carrying the box j, will be then depressed, and through the
cords h, h, the valve will be operated.
This operation has brought the pallet ut, of the tip, into an acting position before
the shoot, so that the next coin passing down the same, lodges on the said pallet, .

page_text: is deposited in the box, which was brought by the former movement of the beam
under the said shoot o³, o'.
The machine or apparatus is provided with an outside cup-washing bowl w, set
back within one of the walls of the outer casing, in order to admit of the bowl
being made larger than would otherwise be admissible, if the same was placed
entirely forwards, is the drinking cup suspended by a chain.
OPERATION.
Assuming the main liquid supply tank to be filled with lemonade or other liquid
to be supplied on prepayment, and assuming that the mechanism located beneath
the said tank, and enclosed within the casings, to be in the positions as represented,
on the placing of a coin through the coin slot o, o', the same passes down the throat o²,
and into the chamber o³, and upon the right hand side pallet 3, of the tip . The
weight of the coin tilts the said tip upon its pivot v², from left to right, and directs
the coin down the shoot o, and from thence it is deposited in the box j, situated at
the end of the right hand arm of the rocking coin beam i.
The weight of the coin now depresses the said right hand arm of the said rocking
beam, and in its path, or just before it passes home, the end, of the balanced
bottom j, strikes the stop k, and the said bottom is opened outwardly, and the coin
liberated, which now falls, or rolls through the mouth, and down the branch I', and
from thence down the race l, and is delivered into the cash box /^.
The rocking of the beam gives a like rocking movement to the rock arm o̟,
through the instrumentality of the cords or wires h, h, and through the said
rocking, the stalk e is rotated to a quarter of a rotation, and with it the valve f
The channel f, is then brought coincident with the ports or passages c, and y, and
the chanuel, coincident with the ports or passages and p. Liquid from the
main supply tank now flows through the said ports of the cock, forces the air
confined within the said passages and measuring vessel r, up the tubes, which is
then, with the measuring cups, filled with liquid, ready to be delivered on the
introduction of the next coin.
By making communication between the passage q' and p, the liquid contained
within the measuring vessel, and also within the air vent and passage, passes
down the delivery pipe q, and from thence into the trough t, down the same, into
the box end t, and out of the bib of the delivery nozzle t. Drippings fall from
the tip of the end to, of the spout t, into the vessel made to receive them.
The passing of another coin through the coin slot, reverses the positions of the
channels of the valve, so as to make communication between the empty measuring
vessel, and the main liquid supply tank, and the filled measuring vessel with the
delivery pipe, hence the alternate filling and emptying of the measuring vessels,
which, with their passages and air vents, are made to contain a given or nearly
given quantity of liquid.
On the liquid being consumed from the tank, the float in, falls with it, and brings
taut the cord m³, through the intervention of which, when the float reaches the
bottom of the tank, the plate n, is closed, by the taut cord running and pulling
over the roller n³, hence the prevention of coins being placed within a machine
after the liquid has been consumed.
Figure 11 represents in vertical section, an automatic prepayment machine, for
the delivery of wines, spirits, beer and other like liquids in measured quantities in
exchange for one or more coins. This arrangement, which is an amplification or
an adaption of, the principle comprehended in the liquid delivery machine as herein-
before described, comprehends a measuring cylinder, having working within it, a
plunger, constituting, as it were, a division or diaphragm, between the space to be
emptied and that to be filled, and which cylinder is in communication with outlet
and inlet passages leading to and from the body of a four-way cock, over the ports
of which, a channelled or box valve turns, through a quarter of a rotation.
The coin lever, which is shown depressed, and in the act of operating the valvė,

page_text: and releasing the coins, is connected to the stalk of a valve, so that when brougat
alternately in front of certain parts of the cock, the ends of the cylinder are
alternately emptied and filled.
Figure 12 represents a front elevation of the said machine or apparatus showing
the counterpoised coin lever, in a position to receive coins, under the coin shoot.
In Figures 11 and 12, a is the outer casing, ŕ is a cylinder, closed at both ends, and
having enclosed within its interior a reciprocating plunger, with packing rings r²,
at its ends.
d is a four-way cock, having a delivery port p³, leading to a delivery pipe p,
terminated by a nozzle or bib t'. ',,are passages or ports leading to the measuring
cylinder r, through passages 7, 7. is a passage or port leading from the supply
pipe c, whose other end is connected with a barrel or other vessel, tank or the like,
containing wine, spirits, or beer to be supplied.
Located and working upon the back side of the body of the said cock, is a valve f,
with channel ports,, which come coincident alternately with two of the said
passages or ports for the filling and emptying of the cylinder, which is of an
internal cubical capacity, adapted to measure out given quantities of liquid, con-
sequent upon the positions of regulating screws 7, 7, taking through the middle of
the ends of the said cylinder.
The positions of the pins relative to the plunger regulate its traverse, and so:
regulate the measuring-out of determinate quantities.
Thus, if the screws be made to project more or less inwards, so the traverse of
the plunger is limited accordingly, and the quantity of liquid delivered is thereby
regulated.
The valve f, is fast upon one end of a stalk e, whilst the other end of the said
stalk carries a loosely mounted rock lever g, and a fast ratchet wheel g'. The rock
lever also carries a pawl g³, kept down by a spring g³. The outward end of the
said rock lever has a coin tray j, coming under the shoot o³, of a coin slot o,
directed from one of the sides of the casing. The other end of the lever is
counterpoised by a weight g, so that as coins are passed through the coin slot,
and travel down the coin shoot, they slide upon the tray j, when the tray end of
the lever is depressed, and the valve turned through a quarter of a rotation, through
the turning of the valve stalk, through the intervention of the ratchet wheel,
acted upon by the pawl g³, consequent upon the rising of the weighted end of the
said lever.
OPERATION.
Assuming the supply pipe c to be connected with a barrel of wines or spirits,
the passing of coins through the coin slot, rocks the lever g, and through its
instrumentality, the valve has given to it, a quarter of a rotation, which brings the
channel or port, of the valve, coincident with the ports or passages 9', c, of the -
passages c, q* and the channel f, coincident with the ports or passages 9³, p', of
the passages P, and 9. so that when the channels of the said valve are in the position
as represented in Figure 11, liquid is being admitted to the right hand side of the
plunger, and the liquid on the left hand side of the plunger within the cylinder, is
being delivered in exchange for the coins introduced, and which liquid passes out
of the bib of the delivery nozzle t'.
Immediately the rock lever has reached the point of lowest oscillation, the coins are
slid from the tray, when the said lever returns to its normal position, by the pawl
wiping over the backs of the teeth.
The passing of a second payment of coin or coins through the coin slot, gives
another oscillation to the lever, and the liquid, which by the previous action, was
allowed to pass into the cylinder, through the weight of its vertical column, is now
delivered, and the other chamber, which was formerly emptied, is now open to the
supply, which gravitates through the system of passages, and thence into the
cylinder, and by it the plunger is traversed to the other end of the cylinder, or up
to the stop.

page_text: Where two or more coins are employed in payment of a quantity of liquid, I
prefer to use such an expedient as represented in Figure 12*.
o, is the shoot leading from the coin slot o, with the outlet o*, directed
immediately above a tray 9, at the end of a counterpoised tip lever 10, and which
tray 9, comes immediately above a coin box j, connected to a counterpoised lever g,
and it will be understood that the tip lever 10, is adapted to tip, only on a second
or further, coin being run onto the tray, when they are collectively shot from. the
same into the tray j, below, which latter then operates the lever g, for the working
of the machine, as before described
Figure 13 represent the upper part of another form of my invention for the
supplying of borril, coffee, or other hot or heated liquids in exchange for two
prepaid coins. It will be seen that the said arrangement is provided with a three-
way cock, with the passages of it, leading directly to a hot water supply, a mixing
chamber, and an outlet or a delivery, and that some of the primary parts of the said
apparatus are controlled by floats.
Figure 14 represents the lower part of the said machine showing the double or
dual shoot, leading from the coin slot, and the means employed for intercepting
and releasing the second coin introduced.
Figure 15 represents a vertical section of the machine, upon the dotted lines
Figure 14.
Figure 16 is the front face of the valve, showing the single channel or port.
a is the outside casing of the pillar or upright machine, b is a hot water supply
tank, heated by a lamp or burner 6, resting upon a bracket, located underneath
its bottom.
d is a three-way cock with a hot water supply port c', leading from a supply
pipe c, directed from the hot water supply . p is the delivery port, leading to a
delivery pipe p, and g', is a third port or passage, leading to an upright passage 7,
which empties itself into a measuring and mixing vessel r, closed at top, and being
provided within its interior with a float z, having a stalk 2, terminated by a double
valve,, located within a supplementary and essence chamber y³, of an essence
vessel y, disposed immediately above the said measuring and mixing chamber r.
The inlet and outlet to the said chamber y, have valve seatings y³, y. The essence
within the essence chamber, is a prepared liquid or semi-liquid substance, such as
bovril, which is measured out and mixed, with a given quantity of hot water
supplied.
Leading from the said measuring and mixing chamber is a third chamber 1,
having an inlet passage 1º, and an upright hollow stalk 1b, which has working
within it a rod 2, terminated by a float 2, at its lower end, whilst the upper end
of the said rod is jointedly connected to an arm 2, (see Figure 14) jointed at 2°,
and with the fore end of the arm coming under a pin 3, of a turning plate 3,
having a finger 3b, directed from the periphery of it, and which, when in the position
as represented in the said Figure 14, comes within the path of the second coin intro-
duced, whilst the first one, which is a pilot one, as hereinafter described, works the
tip v, and brings a stud o, when the same is moved from right to left, behind a
hanging rod 3, hanging loosely upon the axis 34. The said plate 3 has also a second
stud 3, against which the swinging rod 3º, comes when the tip and its stud v, v², is
moved from right to left.
The throat o³, of the slot, leading to the dual shoots o, o, has a casing o', and a
chamber o, having stops for regulating the movement of the tip, which is jointed
at v².
Fixed on the stalke of the valve f, which comes in front of the face of the body
of the three-way cock, is a rock lever g, connected by cords, wires or the like h, to
a rocking coin beam i, as represented in Figure 10.
The valve, has only a single port, which is brought alternately coincident
with two of the ports or passages of the cock, for delivery, measuring out, and
mixing.

page_text: OPERATION.
Assuming a coin to be placed in the coin slot, and the same to pass down the
coin shoot, it then passes into the left hand side of the tip, with the coin slot or
shoot o³, open.
The weight of the coin within the balanced tip v, will cause the same to rock 5
upon its centre, and to be then brought over into the position Figure 14, and by
such bringing over from right to left, the stud o, impinges against the hanging
rock 3, and through it the plate 3, is rotated, by the said rod coming against the
stud, and by such rotation the finger 3b, is placed in a vertical and intercepting
position, as shown, hence the blocking of the second of two coins introduced in pre-
payment of a single quantity of hot coffee or beverage.
The coin descending down the shoot o³, operates a rocking coin beam, as in
Figure 10, and so imparts motion to the rock lever g, and through it a rotation to
the valve f, which makes communication between the ports g¹ and c', of the
passages and c, leading from a hot water vessel b, and to the measuring and
mixing chamber r.
As there is now a clear passage through the said ports, the liquid rises within
the chamber T, lifts the float z, stalk 2, and double valve 23, 2, taking the valve 2*,
from the seat y', whilst the valve ³, closes the valve passage
The essence contained within the supplementary chamber y³, now passes or runs
into the mixing and measuring chamber r, and the hot liquid rises into the
supplementary chamber, and also into the third chamber 1, through the passage 1ª,
and lifts the float 2, which pushes upward the rod 2, and by it the arm 2b, is
turned upwards upon its joint 2, and with its free end pressing upon the stud 3*,
hence the turning round of the disc 3, and the taking of the finger 3° from out of
the path of the second coin 5, when the same drops onto the right hand side of the
tip, which then rocks from left to right, and delivers the second coin 5, down the
branch o, of the dual shoot, and when reaching the bottom of the said branch, it
falls into the box at the other end of the rocking coin beam, when the same turns,
pulls the rock lever g, in a reverse direction, rotates the valve, and brings the
portf, coincident with the ports q', p', of the passages q and P, when the measured
out and hot mixed bovril or like liquid, is then delivered to the payee in exchange
for the two coins.
I wish it to be understood that the said last named machine, which is an
amplification of the preceeding ones, is as applicable to the supply of cold liquids,
having essence, as to hot liquids.
When the coin or coins employed are insufficiently heavy to directly operate the
valve, through the medium of a counterpoised lever or other means, I employ an
auxilliary device, such as clockwork or like mechanism, whose duty is to assist the
introduced coin or coins in properly operating the valve.
Thus, I may employ a device in the form of auxilliary clock mechanism, which
on the coin, say a threepenny piece, being dropped into the machine or apparatus
through the coin slot, the said coin falls or comes upon the lever end of a detent of
the said mechanism, hence the releasing of the same, which thereby operates or
turns the valve, whose resistance under ordinary conditions could not be overcome
by the simple weight of a small coin.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First-In an automatic prepayment apparatus, or machine for the delivery of
lemonade or other beverages or drinks in exchange for coin, the alternate measuring
out and delivery means as described, and set forth in Figures 1 to 12ª.
Secondly -In automatic prepayment liquid delivery mechanism, the employment

page_text: in connection with alternate measuring and delivery means, of a four-way port cock,
whose passages, are alternately coupled or paired, through the instrumentality
of a valve, or a double channelled valve, or box valve, substantially as described,
and set forth in Figures 1 to 12ª.
Thirdly: In automatic prepayment liquid delivery mechanism, a four-way port
cock, in combination with a direction valve, or a box or double channelled direction
valve, as described and set forth in Figures 1 to 12ª.
Fourthly In automatic prepayment liquid delivery mechanism, the employ-
inent of two or other number of measuring vessels or.cylinders, with combined inlet
and outlet passages, as set forth in Figures 1 and 3, whereby an alternate
measuring and delivery of liquid is performed, through the instrumentality of the
coin or coins tendered in prepayment.
:
Fifthly -In automatic prepayment liquid delivery mechanism, the combination
with the measuring and delivery vessels or cylinders, with vents and inlet and outlet
passages, of a four-way cock, with a channelled or double recessed faced valve, as
