Improvements in Change Makers and Indicators, more especially for
use with Cash Registers and Check Tills.
I, GEORGE CROYDON MARKS, Consulting Engineer, of 18, Southampton Build-
ings, Chancery Lane, London, W.C. (being a communication from Mast, Foos &
Company, a body corporate, Manufacturers of Cash Registers, etc., of Springfield,
in the County of Clark, and State of Ohio, U.S. America), 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:-
-
My invention relates to a machine for automatically making change. It also
relates in its nature to an indicating device which shall indicate the amount re-
ceived and the amount retained.
My invention is especially adapted for use in connection with cash registering
devices, but is capable of being used simply as a change maker.
The object of the invention is to provide means by which, when change is desired
for a certain piece of money, the amount may be indicated and then by operating
the machine the exact change for said amount will be automatically discharged
from the machine.
A further object of my invention is to provide means whereby, in a transaction
in which change is required by reason of the presentation of a larger sum than the
amount involved in the transaction, the proper change can be automatically dis-
charged from the machine by the operation of the devices which indicate the
amount received and the amount involved in the transaction, the difference, in
the form of change, being automatically computed and discharged from the
machine.
A further object of my invention is to provide means by which the amount of
any transaction shall be registered, while the difference between said amount and
a larger amount given in settlement therefor shall be automatically computed and
discharged from the machine, constituting the correct change.
I attain these objects by the constructions shown in the accompanying drawings,
in which

page_text: In carrying out my invention 1 employ a series of coin holders adapted to con-
tain all the necessary coins which will be used in making change within the limits
of the machine, there being one holder for each denomination of coin used. The
coin holders are provided with discharging devices which, when operated in their
proper position, will discharge a single coin from each holder. Means are pro-
vided by which the discharging devices may be set into position for operation, and
when in such position will be operated by the other parts of the machine to dis-
charge a single coin from each coin holder, but when thrown out of the operative
positions the discharging devices will remain at rest.
"
One of the primary features of my invention consists in the employment of two
sets of actuating devices, preferably in the form of keys, each numbered to represent
the amount with which it is to deal; that is to say, the numbers on one set of
these devices, which, for the purposes of this specification I call "cash keys," repre-
sent the amount received in any transaction. The numbers on the other set, which
I will call sale keys," represent the amount to be applied or involved in the
transaction. Connected to these actuating devices is mechanism, which, when a
key of the first set is operated, will set into position for operation the discharging
devices of the coin holders representing coins of different value enough to make up
the amount of the cash key, but in the form of subsidiary coin or change. The
other set of keys or actuating devices are so connected with the first that when one
of these, sale keys is operated it releases or throws out of operative position the
coin discharging devices corresponding in value to the sale key operated, so that
the coin discharging devices representing the difference between the two amounts
indicated on the two sets of actuating devices will still be left in position for oper-
ation, and when operated will discharge the proper change.
In the drawings, aa represents a frame, which will usually be embodied with or
enclosed in a casing which will cover up all the operating parts so as to be access-
ible only to the proprietor, who will carry a key, after the manner of the cash
registers now in general use.
At one end of this machine is a series of coin holders preferably in the form of
tubes a, a, a, a, a, a, a, (see Fig. 5). In the machine which I have illustrated
which, it should be stated, is made of the simplest character for the purpose of
illustration, there are seven of these tubes. The machine is designed to operate
in connection with transactions in which 5, or a multiple of 5, forms the unit.
These tubes therefore, are designed to hold fractional currency of the proper
denomination to make the change, such as five cent pieces, ten cent pieces, twenty-
five cent pieces, fifty cent pieces and one-hundred cent pieces or dollars. aa² are
for five cent pieces, a³a for ten cent pieces, a for twenty-five cent pieces, aº for
fifty cent pieces, a' for dollars. These tubes or coin holders rest on a base or
shelf b, having on the top a depression adapted to receive a single coin of the
denomination of the tube which rests thereon. Immediately back of this shelf
and within the frame or casing, is a slide 2, which, when moved outwardly, will
pass through the depression and carry a single coin from the bottom of the
tube or holder belonging thereto, there being an opening in the side of the tube
at the bottom for this purpose. On each of the slides there is mounted a barrel
or cylinder 63 through which there is extended a spring-actuated plunger b. Above
each of the plungers 6+, resting normally thereon, is a hinged plate 65, and above
each of the plates is an arm or finger c, each of which is secured to one of a series
of rods, 10, 2, and 0. These rods c, etc., extend entirely across the machine
immediately above a series of cash keys ', which are numbered to correspond
with certain values which they are to represent, there being in the present case
and for the purpose of illustration nine such keys, as shown in Fig. 1, with ten
cents as the lowest and one dollar as the highest. It will be understood, however,
that any number of such keys may be used and their objects and functions will
clearly appear from the following description.
Each of these cash keys. which is, in fact, a flat bar adapted to move longitudi-
nally in suitable bearings at the front and rear of the casing, is provided with

page_text: one or more pins ², in one side thereof, which are adapted to contact with pins
or projections extending from the respective bars e, cl, etc., so that when a key
is pressed inwardly the bar or bars with which it is connected is partially rotated
so as to bring the finger or projection e in contact with the swinging plate 6 and
cause the same to move the plunger through the barrel 63 so as to project from
the under, side of the slide, which corresponds to the rod or shaft which is
rotated.
The rods or shafts e, etc., in the present machine correspond in value to the
exponents of the letters employed; that is to say, represents in value five cents;
el, ten cents, twenty-five cents; and, fifty cents. The keys are each con-
nected through the medium of the pins and projections with enough of said
rods or shafts to make up the value of said key, but in fractional amounts, that is
to say, such amounts as would represent change for the amount expressed on the
key. For instance, the ten cent key is connected to the two rods e, each of which
represent five cents, the total being ten cents, the amount of the key; the twenty
cent key or bar is connected to the two e's and the co rod or shaft, the combined
amount being twenty cents, the amount of the key; the one dollar key is connected
to the e, two 10's and one c³, the total amount representing one dollar, the
amount of the key as before. It will be seen now that whenever a cash key c¹ is
pushed in, the plungers on the slides 2 which correspond to the fractional amounts
making up the value of that key will be pushed through the slides by the rotation
of the shafts, which, acting through the arms and vibrating plates 6, will depress
said plungers; the construction being such that the rods and rotating fingers c
will stand substantially in line over the plungers, and will remain in this
position and hold the plungers depressed until the rods, are turned back to the
normal position, (see Fig. 2).
Immediately behind each of the plungers and below the slides 62, is a bar 5,
which extends along the entire series of slides 62. This bar is supported on
each side on guides b, and is connected at or near the center to a reciprocating
rod 8. When the rod 68 is moved longitudinally by the means hereinafter to be
described, the bar will engage with all the plungers which are depressed and
will therefore cause the slides 2 to move outwardly through the tubes or coin
holders and will discharge from said coin holders the bottom coin therein, the
amount so discharged corresponding to the amount of the key which has been
operated. The device as thus described constitutes a simple change maker, and by
these constructions it will be seen that whenever one of the keys has been operated
and its operation is followed by a longitudinal movement of the rod 68, and the
har 66, fractional coins sufficient to make up the amount of the key depressed
will be discharged from the coin holders.
I shall now proceed to describe mechanism by means of which, when an amount
less than the amount indicated above is to be applied to a purchase, or as the
basis of a certain transaction, then the amount so supplied will be subtracted
from the amount indicated and the balance only of the amount first indicated
be discharged from the coin holders. This is accomplished as follows: In the
casing, preferably below the series of keys c¹, is a second series of keys d, each of
which keys is adapted when depressed to operate a longitudinally moving bar d'.
These bars are also provided with projections or pins 2, which engage with
fingers on rods or shafts, d¹ºº. These rods, like the rods e, e, etc.,
extend entirely across the machine and correspond in value to the exponents of
the letters representing the same: that is to say represents five cents; do,
cents, etc. At or near one end of the casing of frame the rods, do, etc., are
provided with cam fingers or projections d' which engage with vertical rods d³,
the upper ends of which contact with projections or wings on the rods or
shafts c, clo, etc. The longitudinally moving bars are connected through the
pins and projections with just such bars d', d, etc., as correspond in value
to the sale keys, d; that is to say, the bar representing five cents is connected
to the five cent rod, the bar representing ten cents to a ten cent rod, the bar re-,
ten

page_text: presenting fifteen cents to a five cent and a ten cent, etc.; each bar being con-
nected to one or more of said rods sufficient to make up the value of the sale key
which operates said bar. The keys d, I have shown in the form of levers, which
are journaled on a common rod 8, the inner end of each of said levers being
formed cam-shaped, as shown at de, to engage with the end of one of the bars
so that whenever said lever or key is turned about the shaft d', the bar
pressed inwardly. Springs d, connected to each of the bars ', are adapted to
return them to their normal positions.
will be
The construction thus far described is such that whenever one of the cash
keys is operated, the discharging devices connected to the coin holders will be
placed into operative position so as to discharge an amount corresponding to the
value of said key. If, now, this operation is succeeded by the operation of a sale
key representing a smaller amount, the coin discharging devices corresponding
to this smaller amount will be returned to their normal positions by the partial
rotation of the shafts ³, 10, etc., which, through the medium of the vertical
rods operating against the projections or wings 6, will return the shafts c, c10,
etc., corresponding to said amounts back to their normal positions, thus leaving in
operative position only such discharging devices as correspond to the difference
between the amounts represented on the cash or sale keys successively operated.
The result will be that if these operations are followed by a longitudinal movement
of the rod 68, an amount will be discharged from the coin holders representing
the change out of the amount first indicated after the second amount indicated
has been applied to the transaction which it covers.
Means are also provided by which the amount of any given transaction may be
registered at the same time the change, if there is any, is discharged. I shall
now proceed to describe the mechanism for accomplishing this result, but it will
be understood that the mechanism which I have described for this purpose is
only a type of register, my invention being capable of use with various other
types which are now well-known and in common use, or which may hereafter be
devised.
Arranged in the top of the main casing on a rod e, is a series of numbered
wheels e, provided with rachet teeth e. Pivoted on a rod in the rear of the
casing is a series of oscillating levers e, each of which is connected by a suitable
pin, operating in a slotted opening e, to one of the bars . The lever et
carries at its upper end a pawl e, which engages with the rachet teeth e of one
of the wheels el; a spring actuated pawl e8 engaging with the rachet to prevent it
from turning backwards as it is moved by the pawl e. By this construction,
whenever the bar is operated, the wheel e corresponding to said bar is moved
one notch, the numbers on the wheels being adapted to show the amount registered
on each wheel; this being what is known as a "detail adder."
Pivoted on a rod f in the rear of the casing is a series of levers f', each of which
has a projection f, each alternate lever having its projection f turned in an
opposite direction. Those which project downwardly are in contact with the
bars . Those which turn upwardly are connected by an oscillating lever f³
with the bars c. Each of these levers f¹ carries at its outer end an indicator
rod f, which supports a tablet f at its upper end so that whenever a hard or d
is operated, the tablet corresponding to said bar is elevated so as to display the
number corresponding to said bar at the top of the casing, the tablets being
numbered to correspond to the keys on said bars. The top of the casing is pro-
vided with two display openings through which the tablets corresponding to the
different sets of keys are displayed. These display openings will be suitably
lettered to show what the tablets indicate, as, for instance, the upper series will
read Amount received is $1.00," and the lower series will read The amount
of your purchase is 15. Wait for change," as illustrated in Fig. 11, or any
other words of like import.
Each of the levers f' has thereon a projection f, adapted, as the lever is raised,

page_text: to be engaged by a hook f, having a limited movement on a rod f³.
This rod f
has a pin fo for each hook f thereon, which pin turns in a slotted opening fin
the hub of the hook; the construction being such that the hooks fi are permitted
a limited movement to engage with the projections f" without turning the
shaft f. Whenever the shaft f8, however, is turned a partial revolution, the
pins will cause the hooks fi to turn with the shaft so as to disengage the respec-
tive levers f
I will now proceed to describe the mechanism which I have illustrated for
operating the discharging mechanism of the coin holders, and also for returning
the various parts to their normal positions after an operation is completed.
is
Journaled on the rod, at each end of said rod, is a U-shaped frame ", which
extends along under each of the keys d. A spring normally sustains this
frame and returns it to its normal position, together with any of the keys d
which are operated; the stop projection at one end of the frame being
adapted to limit the movement of said frame, which has an extended lug 4 to
contact with said projection. This frame is also provided near the lug
with a wedge-shaped projection 5, which extends laterally therefrom and rests
in contact with one end of an oscillating lever d, pivoted at d to a suitable
projection on the frame and connected near its other extremity to the longitu-
dinally moving rod 68; the construction being such that when the frame
turned on the rod, the lever d¹ is caused to oscillate and move the rod 68
longitudinally so as to operate the discharging devices in the manner before
described. Pivoted on a stud 18, on the end of the frame, is a bell crank
lever, one arm 2 of which rests in contact with a wedge-shaped projection (2,
on the end of the vibrating lever d; the other arm 23 of said bell crank lever
being adapted to contact with a projection (24 on a clapper arm 2, journaled on
the same stud. The bell clapper arm de rests in contact with a lug on a
vibrating lever des, pivoted at to the end of the frame and carrying at its
outer end a hinged arm or link . A spring connected to the lever des is
adapted to return said lever and the bell clapper arm to their normal positions
after they have been operated by the hell crank lever d by contact with the
arm of said bell crank lever with the cam-shaped projection on the oscil-
dating lever. The bell clapper arm 2 is adapted to operate in connection with
a gong (not shown) to sound an alarm whenever a key is operated. The arm or
link is provided at the top with a laterally-extending projection, which
in its normal, position stands in line with the end of a lever fl, secured to the end
of the shaft 8 which carries the hooks f of the indicator levers f. Whenever
the bell clapper arm is vibrated, the lever 28 is also vibrated, causing the pro-
jection on the link do to engage with the arm f", and thus oscillate the
shaft f to cause the hooks f7 to disengage the indicator levers f¹ and permit
them to drop to their normal positions.
Extending through the main casing from front to rear near the bottom is a
rody, having thereon a spring g', which presses said rod normally toward the front
This rod rests at the rear against the lower end of a pivoted lever ², the upper
end of which is adapted to contact with the end of a sliding bar g³, which has
thereon projections g, one for each of the rods or shafts c, co, etc.
These pro-
jections are, adapted to engage with arms g on said shafts, so that a longi-
tudinal movement of the bar will produce a partial revolution of the rods or
shafts to return them to their normal positions. The front end of the rod g
stands in the path of the U-shaped frame, so that when a key d is depressed
to the limit of its stroke the rod will be pressed inwardly, which, through the
medium of the lever and bar g³ will return the rods forming part of the coin
discharging devices to their normal positions. The bar 93 has its rear end
turned laterally to form an engaging projection 9 which rests in the bifurcated
end of a pivoted lever g. The other end of this lever g' is connected by a link g8.
to the pivoted arm 730. There is also on the arm fa pivoted latch g, which

page_text: lies in the path of the pivoted lever g. This pivoted latch is so constructed
that when the lever g is moved by the bar g³ it contacts with the latch go and
operates the lever fl so as to move the hooks f, when the lever moves in the
opposite direction the latch permits the lever to return to its normal position
without moving the lever f". At the same time through the link connection go,
it draws the projection over the end of the lever fi, so that if the lever 73
is vibrated the projection engages with the lever f", and moves the hooks f
so as to disengage the tablets. Now, the object of this arrangement is as
follows: Whenever one of the rods, el, etc., is turned, it moves the bar g³.
This oscillates the lever g, which, engaging with the latch ", releases all the
tablets which are displayed by oscillating the shaft f8 and the hooks f. The
hooks and shaft, however, are immediately returned to their normal positions by
a spring f as soon as the lever g has passed the latch g. Now, the pins gt-
in the bar engage on one side only of the projection on the rods e, etc.,
so that any of said rods are permitted to turn back to their normal positions
without moving the bar g. Now, if one of the bars d has been operated, the
tablet connected with the bar will be raised into view and held by the hook f.
The projection will, by the same operation be moved away from the end of
the lever f, and if a key is depressed, the lever will be vibrated prior to
the time the bar is returned to its normal position so that the projection
will pass by the end of the lever f" and will not disturb the tablets which are
elevated, so that both of the tablets representing the amount received and the
amount registered respectively, will remain in view until one of the bars e is
again operated, when the tablets will all be released by the contact of the oscil-
lating lever g with the latch g". In case neither of the bars c¹ is operated in the
next transaction, as, for instance, when cash representing the exact amount of
the transaction is received, then the operation of one of the keys d' will elevate
the proper tablet representing said amount and release all the other tablets. by
the engagement of the projection with the lever f".
To provide for making change without making any registration, I employ a
key or lever h, adapted when depressed to simply operate the U-shaped frame d
If the operation of one of the bars is followed by a depression of the key h.
then the full amount indicated by the bar so operated will be discharged from the
machine in the form of change and no registration will take place.
Connected to one end of the U-shaped frame is a segment, having on its
periphery ratchet teeth 2. adapted to engage in a swinging pawl, as the
U-shaped frame is oscillated on the shaft . This pawl will therefore prevent
the return of said U-shaped frame until it has reached the limit of its movement,
when the pawl, becoming disengaged from the ratchet teeth on the opposite side
of the segment, will swing by gravity to a vertical position, and, as the frame
returns to its normal position by reason of the spring 12, the pawl will engage
with the ratchet teeth in the opposite direction and prevent the downward move-
ment of the frame until it has again reached its normal position. This prevents
making an incomplete operation by the depression of a key.
I also pivot to the front bar of the frame ", a series of hooks, connected to
a rod h, which is journaled at each end in said U-shaped frame. This rod h
has at one end a projecting finger, adapted, as the frame is depressed to con-
tact with a cam finger 18 on the frame and turn said rod to cause the hooks to
move forward in the frame. Each key is provided with a projecting pin 49,
which in its normal position stands in line with the hook . If a key is depressed
to move the frame, the downward movement of the frame will cause the hook
belonging to said key to engage said projection and thus unite the frame and key
and cause them to move together to the limit of the stroke thus preventing an
incomplete operation of the key. At the same time the hooks relating to the
other keys which are not moved will be turned to a position under the pins on
said keys and prevent any one of said keys from being operated until all the parts
have been returned to their normal positions.

page_text: At the end of the casing adjacent to the coin holders I preferably provide an
inclined trough or chute i, extending. along at the side of and beneath the res-
pective coin holders so that as the coin is discharged therefrom it will drop into
said trough and move by gravity to a common point at the front of the machine
so that the operator, by holding his hand at the end of the trough will receive ine
entire amount of change from the coin holders.
It is sometimes desirable that more than one coin of a single denomination be
discharged. This, of course, can be provided for by multiplying the number of
coin holders. I have shown in the drawings two coin holders each for five
and ten cent pieces. It may be desirable, however, in some cases in order to
simplify the machine to provide means for discharging two or more coins from the
same holder. I have shown means for accomplishing this in Figs. 5 to 8, inclusive,
connected with the dollar holder a. Instead of having a single discharge opening
at the bottom of the holder of a width equal to the width of the coin, I provide a
sliding gate &, supported at each end by the arms of a yoke , which extends below
the bottom of the coin holder and is pivoted to a swinging plate . The slide b²
is provided at the bottom with a barrel or cylinder, having a spring actuated
plunger 4, which is also carried by the plate ; the construction being such that
as the gate k is elevated the plunger is raised above the slide a corresponding
amount. A slotted opening is provided at the bottom of the tube holder of a
width sufficient to permit the plunger to pass laterally through. Immediately
under the plate are a series of cam lugs m¹, m², m³, each of which is connected to
a rod m, operated by a suitable key in the front of the machine. These cams are
adapted to contact with and raise the plate to different heights. In the normal
position the slide 2 operates the same as any of the other slides, the gate being
down so that the opening at the bottom of the tube holder is wide enough to allow
a single coin to pass. If the cam m¹ is operated the gate and the plunger will
each be raised a distance equal to the thickness of one coin. The result will be.
that when the slide is operated the slide will press one coin and the plunger one
thus making two coins. If the cam m² is operated, two additional coins, or three
in all, will be discharged. If the cam m³ is operated, three additional coins, or
four in all, will be discharged. By this construction four dollars may be discharged
from the dollar holder at a single operation. It is obvious that the same or sub-
stantially the same arrangement could be applied to any of the other coin holder's
where two or more coins of the same denomination are required to make the
requisite change. The rods m will be connected up in the manner described for
the bars c, and the connections will be such that such bars as are not needed in
the operation of discharging the coin will be returned to their normal positions by
operating a key which represents a transaction as before.
To provide for locking the machine in the event that a coin holder should
become empty, when a coin of that denomination is necessary, I provide means
for preventing the operation of the slides unless a coin is in front of said slide or
slides. This is accomplished as follows: In the bottom of each coin holder is a
pivoted pawla, which is weighted so that a coin of a given denomination will hold
the pawl flush with the bottom of the tube holder. The weight at the lower end of
.cach pawl is such that when the weight of the coin is removed from the upper end
it will turn by gravity so as to project through the bottom, of the tube holder 'and
thus prevent the operation of the slide until a coin has been placed thereon. For
such tube holders as are provided with means for discharging more than one coin at
a time, I provide additional means for locking the device, because it may happen
that where two coins are desired, and there was only one in the machine an
operation would be performed which would not give the correct amount of change
To accomplish this I place in each of the tube holders a plug or stop n', which
rests on top of the coin and is of substantially the same diameter as the holder.
This plug is formed of greater width than the coin to be discharged so that it
cannot be discharged through the opening in the bottom of the tube or holder. If
at any time there is not sufficient coin in the tube to furnish the proper amount
i)

page_text: necessary to make the change, this plug will be engaged by the discharging
mechanism and the operation of the machine will be prevented.
In Fig. 10, I have shown a modified construction in which the shafts do, do, etc.,
are dispensed with; the two sets of keys being adapted to operate the same set of
rods and bars; the keys in one series being adapted to set said rods and bars into
position to discharge the proper amount of coin represented by said keys, and the
keys in the other series being adapted to return such rods and bars as represent the
value of said keys to their normal positions. In this case the change keys are
placed below and the registering keys above. The bar el is adapted to be operated
by a series of keys o, which are strung on a rod o¹, extending across the front of the
machine; a projection o² engaging with a notch or shoulder o³ on the bar c¹.
The pins on said bar engage with the projections on the rods as before.
The bar is further provided with a pin o¹, which engages with a projection o5 on
that rod which corresponds to the value of the key. A registering key 2, which
is adapted to operate any suitable form of registering device, is adapted when
operated to contact with one end of a vibrating lever p¹, journaled on a rod 22, the
opposite end of which is adapted to engage with a shoulder of on the bar c¹ and
return said bar to its normal position. The bar shown in the drawings represents
the ten cent bar with its pins connected to the two five cent rods. If the five cent
registering key should be operated after the ten cent change key has been operated,
one of these five cent rods would be returned to its normal position by the five
cent key which would have a projection to engage with said five cent rod. The
other one would remain in position to set the five cent discharging devices. The
bar for a twenty cent change key would be connected to the two rods and one
rod clo. If, now the ten cent registering key, which is the one represented in the
drawings, is operated, it would by reason of the projection o³, return the rod c¹0 to
its normal position, thus leaving the discharging devices corresponding to the
rods to be operated giving the proper change.
It is obvious that various other modifications may be employed to accomplish the
same or substantially the same result without departing from my invention. The
invention will usually be employed in connection with cash registers, which may be
any of the well known types now in general use, with a cash receptacle which may
be employed for keeping such. of the cash as is not required for the coin holders.
The capacity of the machine may be extended indefinitely by providing additional
rods and bars and keys for operating the same. When used in connection with
cash registers such as are now in use, the means for operating the discharging
mechanism will be obtained from such moving parts of the device as is best
adapted for the purpose. The indicating tablets and the registering mechanism may
be the same as now in common usc.
In Fig. 2, I have shown a modification in a portion of the discharging devices.
Instead of using the hinged plates 65, adapted to rest on the plungers 6, I
substitute for the fingers on the rods, etc., cams r, which contact directly with the
plungers. These cams are made of sufficient length to permit the movement of the
slide plungers longitudinally along the same.
The above device as described is designed for use with coins for currency
systems employing the decimal system, as, for instance, such as used in the
United States of America, the arrangement of the coin holders herein shown and
described being especially adapted for the fractional currency of said system. It
is obvious that the same thing may be applied to any other system of money by
making the coin holders correspond to the frictional currency used in the
system, only a sufficient number of coin holders being necessary so as to
provide for all the fractional coins necessary in making change for certain given
transactions.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what'
I claim is:-
1. In a money changing machine, the arrangement of cash keys and sale keys in

page_text: connection with money holders and money discharging devices, the cash keys being
so connected to the discharging devices that when operated the discharging devices
corresponding in amount to the cash keys will be brought into operative position,
the sale keys being so connected that their operation will return to their normal
inoperative positions the discharging devices corresponding in amount to the sale
keys, whereby the difference between the amounts represented by the different
series of keys will be discharged after an operation of said keys.
