the Office of the Commissioners of Patents on the 16th February 1883.
BROWNE WOLSEY WEBB, of Harrington Square in the County of Middlesex,
"IMPROVEMENTS IN ELECTRICAL SELF-REGISTERING MONEY TILLS, PARTS OF WHICH
IMPROVEMENTS ARE APPLICABLE FOR OTHER PURPOSES
>>
My invention relates chiefly to improvements in the tills described in the
Specification of my former Letters Patent, dated 8th July, A.D. 1881, Nº 3009, but
the said invention comprises electrical apparatus for automatically registering the
amount of money inserted in the said tills, parts of which electrical apparatus are
applicable for other purposes.
One important novel feature of my present invention is the employment of an
inclined plane or chute below each of the apertures for the reception of the coins.
These chutes are constructed in such a manner that the coins for which they are
intended will just pass down between their vertical sides, and I combine with.each
chute a spring or springs attached to, and projecting a short distance through,
one of the said vertical sides in such a manner that as a coin of the desired size
passes down the chute it presses the said spring outward and thereby completes
an electric circuit for operating the corresponding dial of the registering
apparatus.
In constructing the electrical registering apparatus I employ toothed wheels
similar to those described in the said former specification, provided, if necessary,
with a spring-tooth pivotted to one side of the wheel. These wheels are mounted
upon shafts or arbors carried in bearings in a suitable framework and having dials
fixed to them at one end. The said dials are marked with the necessary figures to

page_text: r
indicate in pounds, shillings and pence or other monetary scale, the amount that
has been inserted in the till.
I usually mark the first dial, when it is to indicate pence, with the figures from
one to twenty four inclusive, and I arrange the corresponding toothed wheel in
such a manner that it will be turned one twenty-fourth part of a revolution when
a halfpenny is inserted, and one-twelfth of a revolution when a penny is inserted.
I accomplish this result as follows, that is to say, I fix a ratchet-wheel on the shaft
or arbor carrying the said toothed wheel and I combine, with the said ratchet-
wheel, a pawl or catch arranged to be operated by an armature when attracted by
an electro-magnet, so that when a halfpenny is inserted in the aperture intended to
receive it and passes down the chute, the circuit around the said electro-magnet is
completed and the armature being attracted causes the said ratchet-wheel to turn
one twenty-fourth of a revolution. In the chute for the pennies I provide two
contact springs, so that, when a penny is inserted and passes down the said chute,
it makes and breaks the circuit twice and thus causes the ratchet-wheel to turn
one twelfth of a revolution. I provide a similar device in combination with the
dial for indicating shillings, which is marked with the figures one to twenty
inclusive. The ratchet-wheel in this device is turned one twentieth of a revolu-
tion when a shilling is inserted and one tenth of a revolution when a two-shilling
piece is inserted.
The dial for indicating pounds is combined with a similar device for rotating it,
arranged in such a manner that, when the circuit around the electro-magnet is
completed by a sovereign passing down the chute, the said dial will be turned one
twentieth of a revolution, if twenty figures are-marked thereon, or otherwise
according to circumstances.
I provide the following means for operating the dials for indicating pence and
shillings in order that they may register the insertion of sixpences and half
sovereigns, that is to say, I arrange the mechanism in such a manner that, when_a_
sixpence is inserted in the aperture designed to receive it, it will complete the
circuit around an electro-magnet for a sufficient length of time to permit the
armature to move the pence dial half a revolution. To accomplish this result I
place upon the shaft or arbor of the said dial a pinion having a ratchet-wheel
secured to it at the end next the toothed wheel. A pawl is pivotted to the said
toothed wheel and is caused by a spring to engage with the said ratchet-wheel, so
that the said pinion can rotate independently of the toothed wheel in one direction,
but, when rotated in the opposite direction, will cause the toothed wheel to rotate
with it. I form the armature of the said electro-magnet with a segmental rack or
toothed segment which gears with the said toothed pinion, so that when the
armature is attracted the said pinion and the toothed wheel are caused to turn
half a revolution. To prevent the momentum of the toothed wheel from carrying
it round farther than necessary, I sometimes arrange a stop in combination with
the said armature, so that, when the armature has reached the end of its stroke,
the said stop will be moved into the path of one of the teeth of the said toothed
wheel and will arrest the movement of the latter. Similar devices are arranged in
combination with the shillings dial for the purpose above specified.
In order that the sixpences and half-sovereigns, on their passage from the
aperture to the draw of the till, shall complete the circuit for the required length
of time, I arrange a pivotted lever below the chute for the passage of each of these
coins, in such a manner that the coin will slide off the chute on to one arm of the
said lever and momentarily depress the same before dropping into the drawer or
receptacle. The other arm of the said lever forms an armature for an electro-
magnet which is in the same circuit as the electro-magnet for operating the dial.
When the said lever is depressed by the coin as above described the circuit is
completed and the said lever is maintained in position by the attraction of the
magnet until the armature provided with the rack or toothed segment has reacl:ed
the end of its stroke; at this moment the said armature makes contact between

page_text: two springs and short-circuits the two electro-magnets. The said lever being no
longer attracted resumes its normal position.
It is not necessary, in all cases, that the electrical registering apparatus should be.
fitted inside the till. It may, if desired, be placed at a considerable distance
therefrom and connected therewith by suitable conducting wires.
The electro-magnet and pivotted armature for operating the pinion and dial as
above described, are, according to my present invention, constructed in a peculiar
manner whereby I obtain a greater amount of travel or length of stroke of the
said armature than is practicable with pivotted armatures as heretofore made.
With armatures of this kind as heretofore constructed, only a very limited
movement can be obtained, because the armature must be within a certain distance
from the magnet in order that it may be attracted when a current is passed
through the magnet-coils. But I construct the magnet and armature in such a
manner that part of the latter always sufficiently near to the magnet to be
within the magnetic field thereof, and that, as the armature is moved by the
attractive force of the magnet, other parts of the said armature come successively
within its magnetic field. For this purpose I sometimes make the cores of the
magnet with polar extensions whose upper surfaces are made in the form of an arc
of a circle described upon the pivot of the armature as a centre. I also construct
the armature with a correspondingly curved projecting arm at its upper end, and
with a flat rib at right angles to the said arm, which rib, when the armature is in
position, passes a short distance between the two polar extensions. When a current
is passed through the magnet-coils, the attractive force of the magnet acts upon
the end of the said rib and arm, and, as the armature turns upon its pivot, the said
rib passes between the polar extensions while the curved arm passes over the upper
surfaces thereof. This peculiar construction of magnet and arinature forms a novel
feature of my present invention, and can be applied to electric bells or other
apparatus in which a pivotted armature is required.
In my improved registering apparatus I fix the aforesaid segmental rack on the
upper surface of the said curved arm of the armature
I prefer to attach the electro-magnets and pivotted armatures to a base plate of
soft iron, so that the upper end of the armature will constitute a magnet-pole of
opposite name to that of the upper end of the electro-magnet and thus increase the
attraction between the armature and magnet
I further improve the tills, according to my present invention, by fixing one or
more division plates upon the inclined plate which supports the money before it is
dropped into the drawer or receptacle, so that the silver and gold can be kept
separate from the copper, and separate from each other if desired. I also sometimes
arrange the till in such a manner that the silver and gold will be received in a
locked drawer and the copper in an open receptacle from which it can be withdrawn
to be used as change.
The form of the till may be modified in various manners, and I sometimes make
it with a drawer at the back, and with the glass window, through which the
money is seen when resting upon the inclined plate, at the front.
In some cases I arrange, in combination with the drawer, a device, such as that
hereinafter described, for releasing and moving the inclined plate when the said
drawer is opened. The device which I prefer to employ for this purpose, I construct
as follows, that is to say, I provide a lever which is pivotted to the frame or casing
of the till in such a position that it will be operated by the drawer immediately
the latter is opened, and will be released when the drawer has been opened to a
certain extent. The said lever is also arranged so that, when the drawer is closed,
the lever will be raised and again engaged with the drawer without acting upon
the inclined plate. To one end of this lever I attach a cord or chain, which is also
attached to a pivotted catch held in engagement with a stop by means of a spring.
I also, in some cases, arrange the said lever so that it will complete the electric
circuit in which the bell is included, when the said drawer is opened. I can also

page_text: provide a push-knob, if desired, for operating the said lever by hand to unlock the
inclined plate and move it to permit the money to drop into the drawer or
receptacle.
Another novel feature of my present invention is an improved change indicator
which is so constructed that the glass door is not required, and the glass can be
permanently fixed in front of the dial. For this purpose, I fix one of the hands
or pointers, for indicating the amount upon the dial, to a central spindle; and the
other hand or pointer I fix upon a sleeve or hollow spindle which passes over and
surrounds the said central spindle. Each of these spindles is provided with a
toothed wheel which gears with a pinion. These pinions are each fitted upon a
spindle which passes through the casing of the apparatus and to which is attached
a milled wheel or other suitable device for rotating the said pinions by hand.

by the said Browne Wolsey Webb in the Great Seal Patent Office on the
16th August 1883.
BROWNE WOLSEY WEBB, of Harrington Square, in the County of Middlesex,
"IMPROVEMENTS IN ELECTRICAL SELF-REGISTERING MONEY TILLS, PARTS OF WHICH
IMPROVEMENTS ARE APPLICABLE FOR OTHER PURPOSES "
My invention relates to money tills and its main object is to so construct tills
of the class described in the specification of former Letters Patent dated 8th July
A.D. 1881, N° 3009 as to render the same automatic or self-registering by means of
electricity.
One feature of my said invention consists in providing the till with means
whereby the insertion of coins of different values will be automatically registered
by the same dinl.
My said invention, moreover, comprises the employment of an inclined plane or
chute provided with contact springs or similar devices whereby a coin, in passing
down the said chute, will complete an electric circuit and cause the partial rotation
of a dial by means of suitable mechanism hereinafter described. The said invention
also comprises the employment of a device consisting essentially of an electro-
magnet and a pivotted lever carrying an armature, in combination with a chute
and with a dial and means for turning the same a half revolution when an electric
circuit is completed by the fall of a coin from the said chute upon the said lever.
The said invention further comprises the employment of two or more receptacles
for the coins in combination with an inclined plate provided with one or more
division plates or partitions in such a manner that, when the insertion of the coins
has been registered and the inclined plate is depressed, the copper coins will fall
into an open receptacle whilst the silver and gold coins will fall into a closed
receptacle A pivotted catch is secured to the said inclined plate and means are
provided for disengaging the said catch from a stop-piece by pressure upon a
push-knob or by the opening of a drawer. The said invention further comprises
an improved change indicator which may be adjusted, without opening or removing
the glass cover or lid in front of the dial, to record the amount of money handed
to the shopman or other person to be used for giving change when required.
The said invention also comprises means for correcting and for checking or
arresting the motion of the toothed wheels and dials; means for breaking an
electric circuit, in which an electro-magnet is included, when the armature of the
said magnet has been moved to the required extent; and means for partially
rotating one or more of the dials when the preceding dial has made one revolution;
all as hereinafter set forth for the purposes specified.

Like letters indicate the same parts throughout the drawings
A is the casing or box enclosing the mechanism, A¹ is the receptacle for the
pennies and half pennies; As is the drawer for receiving the silver and gold; R is
a brass plate fixed on the front of the box A and provided with apertures B¹ for the
insertion of the various coins. Bebind and below these apertures I arrange the
inclined planes or chutes 1, 2, 3, 4, 5, 6, 7, which are supported by the cross-bar A³
secured to the sides of the box A. These chutes are so constructed that the coins
for which they are intended can pass freely down between their vertical sides.
The chutes 1, 4 and 7 are each fitted with a contact device consisting of a
spring C fixed at one end to the interior of one of the vertical sides of the chute,
the other end of the said spring projecting through a slot or aperture in the said
side so as to nearly touch another spring C¹.
The spring C¹ is attached to the metal piece or terminal C' fixed to the cross-
bar A³ but insulated from the chute. The chutes 2 and 5 are each fitted with a
device somewhat similar to that just described, but having two pairs of contact-
springs C, C. And the chutes 3 and 6 have no contact springs but are made
shorter than the other chutes, and a device hereinafter described is fitted below
each of them; that is to say:-Beneath the lower end of the chute is arranged a
lever D pivotted to a post D' fixed to the cross-bar A which is secured to the
sides of the case A. The rear arm of the lever D is suitably formed to receive the
coin as it drops from the chute; the other arm of the said lever is held down by a
small spring D fixed to the cross bar A'. An armature D³ is carried by the said
arm and is in proximity to the pole of a magnet E fixed to the said cross-bar.
The armature D³ rests upon the screw D' and can be adjusted relatively to the
magnet by the said screw. Below the rear arm of the lever D is arranged a
contact spring C³, with which the said lever comes in contact when it is depressed
by the weight of a coin, thereby completing an electric circuit in which is included
one of the magnets hereinafter described.
When the coins have passed down the said chutes, they fall upon an inclined
plate F similar to that described in the said former specification, which plate is
afterwards moved to permit the coins to fall into the drawer or receptacle below.
But according to my present invention I fix a division plate G (or any suitable
number of division plates or partitions) upon the inclined plate F, so that the
silver and gold can be kept separate from the copper, and separate from each other,
if desired.
The till shown in the drawings is so arranged that the silver and gold will be
received in the drawer A² which is provided with a lock and key, and the copper
will be received in the receptacle A³ from which it can be withdrawn to be used
as change.
The inclined plate F has fixed to its upper edge a metal rod F¹ provided at each
end with journals whereby it is carried in bearings in the sides of the box A.
Two arms are also fixed to the said plate and the springs H are secured at one
end to the said arms and at the other end to the box A. The plate F is provided
on its underside with a pivotted catch I attached to the said plate by means of the
bracket J and acted upon by the spring K also fixed to the said plate. The
catch I is caused by the said spring to engage with the stop-piece L secured to the
box A when the plate F has been closed by the springs H, thereby locking the said
plate and preventing its movement. A chain M is attached at one end to this

page_text: catch, and at the other end to the lever N which is pivotted at N to the box A
and is beld against the stop-pin O by the spring P, as shown in Figure 3. A push-
knob Q is connected to one arm of the lever N and passes through the side of the
box A. By pressing this push-knob, the catch I is disengaged from the stop-
piece L and the plate F is moved to allow the coins to fall from it. A contact-
spring R is also fixed to the box A so that, when the said push-knob is pressed
inward, a circuit in which the electric bell S is included, will be completed, and
the bell will be sounded.
My improved change-indicator is so constructed that a movable cover or lid is
not required, and the glass can be permanently fixed in front of the dial, the hands
or pointers being adjusted in the manner bereinafter described. T is the dial of
this indicator, and U, U' are the hands or pointers for indicating thereon the
amount of change given to the shopman or other receiver of money. The hand
or pointer U is fixed to the hollow spindle V carrying the toothed wheel V' which
gears with the pinion V. The hand or pointer U₁ is fixed to the hollow spindle W
which passes over and surrounds the spindle V and carries the toothed wheel W
which gears with the pinion W. These pinions are fitted upon the spindles X which
pass through the casing Y and to which are attached the milled wheels Z; or other
Buitable devices may be provided for rotating the said pinions by hand. Small
spiral springs Z' are placed upon the spindles X so that a certain amount of
friction must be overcome in turning the latter.
In Figures 8 to 12, a, a¹ a³ are toothed wheels, two of which a and a¹ are
mounted loosely upon the shafts or arbors b, b¹ and the third of which a is fixed
on the shaft b. These shafts are carried in bearings in the front plate c and rear
plate c¹, which plates are firmly secured to the base-plate d by means of the
standards d. The wheels a, a¹, are made with long hubs a which form the
bearings for the front ends of the shafts b, b¹, and the ends of which hubs are
screw-threaded and each provided with a screw-nut 6 for fixing the dials f,f',
thereon. The dial f³ is fitted upon the end of the shaft b' which is screw-threaded
to receive a screw-nut e.
g, g, g are electro-magnets for causing the intermittent rotation of the toothed
wheels a, a, a2 by means of the armatures h, h1, h2 fixed on the shafts i, i', i'.
These shafts are fitted in bearings in the plates c, c', and carry the arms j, j, j³ each
of which acts upon one of the said wheels, when the corresponding armature is
attracted by its magnet, thereby partially rotating the said wheel. The said
armatures are held away from the magnets by the springs k, k acting directly upon
the armatures h, h' and the spring acting upon the pin passing through the
shaft which carries the armature h². These springs are secured by screws to the
back plate c'.
The shafts or arbors b, b' are made in the form of pinions at the parts marked b*
and ratchet-wheels 1, are fixed upon them adjacent to the toothed wheels a, a¹.
These toothed wheels are provided with pawls 12, 13 held in engagement with the
said ratchet-wheels by springs m, m', so that, when one of the ratchet wheels is
rotated in one direction, the corresponding toothed wheel will be rotated therewith,
but the said ratchet wheel will rotate independently of the toothed wheel in the
opposite direction. Additional toothed wheels a³, a' are firmly secured to the hubs
of the wheels a, a', for the purpose hereinafter described
g, gare electro-magnets for causing the toothed wheels a, a' to be turned a half
revolution by the following means, that is to say :-The armatures h³, h* are pivotted
to the iron plates g* to which the electro-magnets are fixed, so that each of the
said armatures forms one pole or polar extension of the corresponding magnet. The
other pole of the said magnet is made in the shape of a segment of a circle.
The magnets g³, g* have also the armatures h³, he fixed on the shafts ³, i, carrying
the arms, which are each provided with a friction roller j* fitting between the
teeth of the wheel a or a¹ so as to correct the movements of the same, The
armatures ho, ho are held away from the corresponding magnets by the springs k³, k
acting upon the pins i* passing through the shafts, 2.

page_text: When an electric current is passed through one of these magnets, the armature h³
or he will be first attracted thereto and will remove the friction roller j* from the
path of the teeth on the wheel a or a¹ so as to allow the said wheel to be moved by
the action of the said magnet upon the armature h³ or h*.
is an arm pivotted upon a pin or stud j and having a friction roller j* fitting
between the teeth of the wheel a. This arm is held in engagement with the
wheel a² by the spring -which is fixed by means of a screw to the plate c. dis
metal strip which makes contact with the spring & when the mechanism is placed
in the case
n, n' are toothed segments pivotted upon the pins or studs n², n³ fixed in the
brackets n', n³ which are secured to the front plate c. In these segments are formed
the vertical slots o, to receive the pins o' fixed in the armatures ³, 1, so that the
said segments will be operated thereby. The springs ne, n' hold the segments in
their normal position.
Pins or studs p, p¹ are fixed in the brackets n', n³ and upon these pins or studs
are pivotted the levers or arms 9, q', for engaging with the toothed wheels a³, a' in
order to arrest their movement as hereinafter set forth. The arms r, r¹ are also
pivotted upon the pins or studs p, p, and through these aruns are passed the
adjustable screws &, st for breaking contact between the springs t, and t. These
springs are fixed one upon each side of a block u, of insulating material, and
are included in the circuits as shown. The springs no, n7 are also fixed to the
blocks u.
In order to prevent the completion of the circuit through the springs t, t' after
they have been separated by the movement of the armature or towards the-
corresponding magnet, I arrange a spring upon each of the pins or studs p, p',
which springs tend to hold the arms q, q' and r, in whatever position they may
be placed; I also fix pins w, w-in-the-toothed segments n, n', so that, when the
armature or h' is attracted, the pin w thereon will strike against the arm or
and thus cause the spring t¹ to be separated from the spring t. This separation
will be maintained by the spring v until the armature and segment have so far
returned towards their normal position that the pin w strikes the arm or and
again permits contact to be made between the said springs. But the spring v
and the pins w, w³ may, in some cases, be dispensed with if desired.
y, y are posts fixed in the plates g* and having the screws z passed through
their upper ends to enable the travel or stroke of the armatures h³, h, to be
accurately adjusted.
In order that the shillings-dial shall be turned one tooth when the pence-dial
has made one revolution, and the pounds dial be turned one tooth when the
shillings dial has made one revolution. I fix to the toothed wheels a³, a', the
fingers or projecting pieces al*, and I secure to the plate o the blocks a³ and a* of
insulating material, to which are secured, by means of screws, the contact-
springs a, a: When the shillings-dial or the pence-dial has made one revolution,
the finger a comes against the spring a7 and presses it against the spring a
thereby completing the circuit in which is included the magnet g' or g³ for causing
the partial rotation of the succeeding dial.
The operation of the electrical self-registering money till, shown in Figures 1
to 12, is as follows, that is to say when a halfpenny is inserted in the aperture
intended to receive it and passes down the chute 1, it presses the spring C against
the spring C and completes the circuit around the electro-magnet g; this magnet
attracts the armature h and causes the arm j to turn the toothed wheel a one
twenty-fourth part of a revolution, and the dial f is thereby caused to register the
insertion of the halfpenny, the said dial being graduated by halfpennies up to
twelve pence. The chute 2 for the pennies being provided with two pairs of
contact-springs, the circuit including the magnet g is completed and broken twice
when a penny is inserted and passed down the said chute, the toothed wheel a is
therefore moved twice by the arm j and caused to turn one twelfth part of a
revolution, thereby registering the insertion of the penny,. Other ohutes might be

page_text: employed provided with six or eight pairs of contact-springs for threepenny or
fourpenny pieces.
When a shilling is inserted and passes down the chute 4, the circuit including
the magnet g¹ is completed in a similar manner to that described with reference to
the halfpennies, and the dial f¹ which is marked with the Figures one to twenty
is turned one twentieth part of a revolution thus registering the insertion of the
shilling, When a two-shilling piece is inserted and passes down the chute 5 the
circuit including the magnet g' is completed twice and the dial f¹ is caused to turn
one tenth part of a revolution, in a similar manner to that described with reference
to the pennies. The dial f³ for registering the insertion of sovereigns is caused, in
a similar manner to that above described, to turn say one twentieth part of a
revolution when a sovereign is inserted and passes down the chute 7 thereby
completing the circuit in which the magnet g' is included. But the distance
through which the dial f* will be rotated each time the said circuit is completed
must depend upon the graduations on the said dial
When a sixpence is inserted in the aperture designed to receive it, and passes
down the chute 3, the said coin will fall from the chute upon the rear arm of the
lever D and depress the same before dropping upon the inclined plate F, this
depression of the said arm brings it into contact with the spring C³ thereby
The
completing the circuit which includes the magnet g³ and the magnet E.
armature D³ on the other arm of the said lever is attracted by the electro-magnet E,
when the said circuit is completed, so that the said circuit is maintained closed.
until the movement of the armature h³ causes the separation of the springs t, t'.
The said lever, being then no longer attracted, is caused, by the elasticity of the
spring D³, to resume its normal position. In this manner the pence dial is caused
to make a half revolution and thereby register the insertion of the sixpence. When
a half-sovereign is inserted in the proper aperture and passes down the chute 6,
the shillings-dial is, in like manner, caused to make a half revolution and thereby
register the insertion of the half-sovereign
It is not necessary, in all cases, that the electrical registering apparatus should
be fitted inside the till. It may, if desired, be placed at a considerable distance
therefrom and connected there with by suitable conducting wires. The till may be
supported upon a suitable pedestal which may, if desired, contain the battery.
The electro-magnets g³, g, and pivotted armatures h³, h are, according to my
3 present invention, constructed in a peculiar manner whereby I obtain the requisite
amount of travel or length of stroke of the said armature. With the ordinary
pivotted armatures only a very limited movement can be obtained, because the
armature must be within a certain distance from the magnet-pole in order that it
may be attracted when an electric current is caused to pass through the magnet-
coil or coils. But I construct the magnet and armature in such a manner that a
portion of the latter is always sufficiently near to the magnet-pole to be within the
field thereof, and, as the armature is moved by the attractive force of the magnet,
other parts of the said armature come successively within its magnetic field, as will
be readily understood by referring to Figure 9 of the drawings. For this purpose
3 I sometimes employ a magnet with two coils and make the cores with polar
extensions whose upper surfaces are made in the shape of a segment of a circle, and
I construct the arinature with a correspondingly curved projecting arm at its upper
end, and with a flat rib at right angles to the said arm, which rib, when the
armature is in position, passes a short distance between the two polar extensions.
When a current is passed through the magnet coils, the attractive force of the
magnet acts upon the end of the said rib and arm, and, as the armature turns upon
its pivot, the said rib passes between the polar extensions while the curved arm
passes over the upper surfaces thereof.
.
In constructing the registering apparatus, I may if desired fix a toothed segment
5 on the upper surface of the armature, instead of employing a separate toothed
segment as shown in the drawings.
The form of the till may be modified in various manners, and I sometimes make

page_text: it, as shown in Figure 13, with a drawer at the back, and with a glass window A
at the front through which the money can be seen when resting upon the inclined
plate, F.
In some cases I arrange in combination with the drawer, a device, similar to that
hereinbefore described, for releasing and moving the inclined plate when the said
drawer is opened. The device which I prefer to employ for this purpose I construct
as follows, that is to say, I provide a lever which is pivotted to the frame or casing
of the till in such a position that it will be operated by the drawer immediately
the latter is opened, and will be released when the drawer has been opened to a
certain extent. The said lever is also arranged so that, when the drawer is closed,
the lever will be raised and again engaged with the drawer without acting upon
the inclined plate. To one end of this lever I attach a cord or chain, which is also
attached to a pivotted catch held in engagement with a stop by means of a spring.
I also, in some cases, so arrange the said lever that it will complete the electric
circuit in which the bell is included, when the said drawer is opened.
It is obvious that I may somewhat vary the construction of the different parts of
my improved till without departing from the nature of my said invention.
Having thus fully described my said invention and shown how the same may be
conveniently and advantageously carried into practice, I wish it understood that I
claim the above de cribed improvements in or relating to self-registering or
automatic money tills, that is to say :-
First. A money-till provided with means whereby the insertion of coins of
different values will be automatically registered by the same dial.
- Second. The combination of parts comprising the inclined plane or chute provided
with contact springs or similar devices, the dial and means substantially as described
for partially rotating the same when an electric circuit is completed by the passage
of a coin down the said chute, all substantially as, and for the purposes, set forth.
Third. The device consisting essentially of the electro-magnet and the pivotted
lever carrying the armature, in combination with the chute and with the dial, and
means substantially as described for turning the same a half revolution when the
electric circuit is completed by the fall of a coin from the said chute upon the said
lever, all substantially as, and for the purposes, set forth.
Fourth. The combination, with the electro-magnet, of the peculiarly formed
.pivotted armature connected with the segment which actuates the gearing whereby
the dial is operated as, and for the purpose, specified.
Fifth. A money-till constructed in such a manner that, when the insertion of
the coins has been registered and the inclined plate is depressed, the copper coins
will fall into an open receptacle whilst the gold and silver coins will fall into a
closed receptacle.
Sixth. The combination of parts comprising the catch pivotted to the inclined
plate and acted upon by the spring, the stop-piece, and means for disengaging
the said catch therefrom by pressure upon a push-knob or by the opening of a
'drawer, all substantially as, and for the purposes, set forth.
Seventh. The improved change-indicator provided with hands or pointers each
of which is secured to a spindle carrying a toothed wheel adapted to be rotated by
means of a pinion fixed to a shaft provided with a milled wheel or other suitable
device for adjusting the same without opening or removing the glass cover or lid
in front of the dial, substantially as, and for the purpose, set forth.
Eighth. The combination of parts for correcting the motion of the toothed wheel
a or a¹ and comprising the electro-magnet, the armature and the arın provided with
the friction-roller, substantially as set forth.
Ninth. The combination of parts for checking or arresting the motion of the
toothed wheel a or a³, and comprising the toothed or milled wheel a³ or a* and the
pivotted arm adapted to engage therewith when the pivotted armature is attracted
by the magnet, substantially as set forth.
Tenth. The means, substantially as described, for breaking contact between the
springs t and t' when the pivotted. armature is attracted by the magnet, (with or

page_text: without the spring v fitted upon the pin or stud and the pins w, w³ fixed in the
toothed segment), all substantially as, and for the purposes, set forth.
Eleventh. The finger or projection on the toothed or milled wheel a³ or a*, in
combination with the block of insulating material carrying the contact springs or
similar devices, substantially as, and for the purpose, set forth.
Twelfth. The apparatus consisting of the parts constructed and combined as above
described and illustrated in the accompanying drawings, and operating substantially
