Improvements in and relating to Electrically Actuated Cash Drawers
or Registers.
I WILLARD LE GRAND BUNDY of the City of Binghampton in the County of
Broome, State of New York, United States of America, Mechanical Engineer do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to electrically actuated cash. drawers or registers, designed
for use in stores by cashiers and which are adapted to indicate the amount placed
in the drawer each time it is opened, and also to add the several amounts together
automatically.
My object is to produce such a cash, register, and combining with it an adding
machine, to add the amounts each and every time a button or buttons are pressed
to make up the sum placed in the drawer; at the same time to indicate and display
the amount of each purchase on one or more dials; one dial indicating units, another
tens, a third hundreds, or dollar units, and so on, also to provide means by which
two or more dials can be operated to indicate a large amount by operating two or
inore buttons in succession; to release the drawer by the making of a circuit; to
automatically throw the drawer open; to provide means to prevent the re-opening
of the drawer after being fully closed, or to prevent its being re-opened after being
partly closed, without the drawer is first fully closed, and then re-opened by the
pressure upon a button; to provide a double figure button operating to open the
drawer by making a double contact. successively, and simultaneously operating
the disk of units and the disk of tens; to provide means for registering each and
every time the front of the case is opened whereby access is obtained to the
registering dials; to ascertain the total amount taken in; to provide means by
which the amount of each purchase is displayed upon the back of the apparatus, to
show the customer the registry when the back is toward him; to actuate all of the
several mechanisms by the electrical contact of any of the single or double buttons.
My invention consists in the several novel features above outlined, and also in
the other novel features of construction and operation liereinafter described and
specifically set forth in the claims annexed hereto.
It is constructed as follows, reference being had to the accompanying drawings,

=
A, is the outer casing having a vertical back, and having the lower part of the
front projecting forward horizontally.
The upper part of the front is suitably enclosed by a detachable cover locked_and_
-secured-in-any-ordinary manner, and the top is hinged and secured by inside hooks
as shown in Fig. 1.
The lower front portion is also adapted-to-receive-the drawer a, sliding upon
friction rollers, and in the upper edge of one of its sides I cut notches c, Figs. 5,
and 6; d, is a button pivoted upon the casing and having its lower end curved, and
the curved portion serrated transversely as shown in Fig. V.
This button operates as follows:-
When the drawer is closed it hangs free in the front notch c; when it is open it
hangs free in the rear notch c; and when the drawer is partly closed after having
been opened, it lies in an inclined position with its lower end toward the back of the
drawer, so that whenever I then try to pull the drawer open, the serrations will
bite into its upper edge and hold it so that it cannot be opened, until it has been
fully closed-and-when-so-closed-it-can-only be opened as hereinafter described,
and accompanied by the sounding of an alarm.
The upper face of the front projection of the casing is occupied by the key-button
board B, Fig. III, in which the front row el, indicates units, the second row ell, tens
the third row e, indicating double figures, units or tens, and the last row el,
indicating hundreds or dollars. The first and second rows are marked from 0, to 9,
as shown the third row with any combination of double figures, those shown being
multiples of 5, up to 50 and the fourth row is marked from 0, to 9, as shown.
When I wish to increase the capacity I either add another row of buttons, or
substitute a hundreds row for the third or double figure row e, use the fourth

page_text: row for thousands, or tens of dollars, and so on, changing the mechanism connected
to and operated by the buttons, to correspond with the change in the rows of
buttons.
C, is the contact board consisting of spring fingers shown in Fig. 4, as arranged
in rows, the first row ", so disposed and mounted as to coincide with the first row
of the buttons; the second row f11, with the second row of buttons the third row "",
with the third row of buttons; and the fourth row f, with the last row of
buttons.
For perspicuity, I have in the drawings, numbered these contact fingers, to
correspond with the rows of buttons as shown in Figs. 3, and 4.
The board itself, upon which these series of contact fingers are mounted, consists
of a piece of wholly, or partly, non-conducting material, through which the contact
points are vertically inserted, projecting above the top of the board, there being
one under each of the single fingers, and two under each of the double fingers, and
wires are connected to the heads under the board, which I shall hereafter call
button wires.
The points, under the double fingers, are arranged so that one projects farther
above the board than the other, so that when a double button is pressed, the unit
arın, or end, will make the contact first, and then as the button pressure continues
the other or tens arm, by the torsion upon the shank of the double finger will also
make a contact; or the operation may be reversed so as to operate the tens first,
and then the units.
All of these fingers are in electric circuit by means of a wire, and bar g, connected
to the bodies from which the fingers spring, and leading to a battery or electro
magnet.
All of the wires from the contact heads beneath the contact board, are conducted
to the contact board, which consists of a cross bar, back of and parallel with the
contact board, and in substantially the same plane, and being wholly or partially
constructed of non-conducting material, or it may be integral with the contact
board, and it is provided with insulated screws, shown in Fig. 4, as arranged in sets,
the wires from the first row of buttons leading to the unit screws 1; those from the
second row to the "tens" screws 2; those from the third row as follows,. those
from the right arm of each double finger to the unit screws 1; and those from the
left arm to the "tens" screws 2; and the wires from the fourth row to the
"hundreds or dollar screws 3.
وو
Whenever a nought appears on a dollar button, the wire from the nought side
is connected to the nought screw.
These bunches or sets of wires are numbered, respectively 1, 2, 3, 4, 5, 6, 7,
8, 9, 0.
""
From these sets of screws, these different sets of wires are conducted, the unit
wires to the fingers 11, upon the unit switch or shunts 12, the "tens wires to the
fingers 11, upon the "tens" switch or shunts 13, and the "hundreds " (or dollars)
wires to the fingers -11, upon the hundreds switch or shunts 14.
These switches are all of the same construction, consisting of a cylinder provided
with a surface of conducting material, which is in electrical connection with the
battery (not shown) and each is secured upon a shaft 20, journalled in the front
and back of the frame of the indicator. Each cylinder is provided with a series of
shunts 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, one for each of the fingers 11, arranged in a spiral
course upon the cylindrical surface, so that the fingers 11, are successively shunted
as the cylinder revolves, and they are thus insulated from the rest of the conducting
surface of the cylinder.
There is a finger 11, for each wire, of each and every set of wires, and they are
mounted upon a cross bar 11', above and parallel to the switch shaft 20.
The motor to rotate these switches, or each of them, consists of a pinion 21,
(Fig. 17.) rigidly mounted upon the switch shaft 20; a gear 22, (called herein the
crank gear for clearness of identity,) mounted loosely upon an arbor above the
pinion 21, and meshing therewith, and provided with a crank pin 221 as shown; a

page_text: rod 25; having its upper end pivoted upon the crank pin;, a bar 26, (see Fig. 13.).
substantially horizontal, having its outer end pivotally connected to the lower end
of the rod 25, and having its inner end hinged to the casing, as shown in Fig. 6,
and a spring 29, having its upper end connected to the bar 26, adjacent to its
front end, and its lower end secured to the casing substantially as shown in
Fig. 13. This spring is normally under tension, exerting a downward pull upon
the bar 26, and rod 25, so that when released as hereinafter described, it will pull,
the rod 25, down, rotating the crank gear 22, and this rotates the pinion 21, the
shaft. 20, and the switch which is upon that particular shaft, until the proper
finger 11, is shunted upon the switch, all as hereinafter described.
A weight suspended beneath the bar 26, adjacent to its outer end, will operate
the same as the spring.
When an unit button is operated, and contact is made with the unit wire, and
through it, with-a-unit finger 11, the unit switch is rotated by the motor mechanism,
until this finger closes the circuit, at its shunt on the switch, and rests upon the
shunt; and this switches the current from the electro-magnet I, which is the motor.
magnet to the electro magnet H, which is the drawer magnet.
Upon-the- -rear of the drawer. a, I secure a latch hook 15, (Fig. VI.) which
when the drawer is closed, engages with a like latch upon the outer end of the
armature 16, of the magnet H, (Fig. 13).
Then, when the current is switched as aforesaid to this magnet, the armature..
latch is disengaged from the drawer latch, and then a single leaf spring. 17,
(Fig. 13, and, 1) having-one. end secured to. one of the side walls of the case, and
standing out horizontally and inwardly, its free end normally adapted to engage
with the back of the drawer and which is compressed by the pressure of the back.
of the drawer against it, when it is closed, throws the released drawer_quickly
outward upon the rollers b, and opens it far enough to give free access to the
interior. When thus being opened the lock button d, rides freely over the front,
notch c, into the rear one, along over the top edge of that side of the drawer.
Simultaneously with the operation of a button, the contact fingers, being
connected to the battery-by-the-positive wire-60, (Fig. 19.) a circuit is made
through one of the contact fingers, as, Fig. 4, its contact point, and one of the-
bunches of wires, to one of the sets of switch fingers and through the finger con-
nected by the wire-leading from the button operated to the finger. corresponding
in number to that of the single figure button operated. These fingers are normally
--in-circuit: with the switch casing,, or outer surface, which is of conducting material
the gear 19; sleeve 20%, and the arm 70, dependent from the sleeve is in com-
munication with the electro-magnet-I. This sleeve-is-insulated-from the frame
work which carries the switch, and in which the shaft is journalled. When a
button is operated and through the spring, finger beneath it, makes a circuit,
through the unit branch of wires, and fingers, for instance, the unit switch, and
electro-magnet I; the armature.18, is released from its engagement with the tooth.
of the gear 19, and drawn down into contact with the, magnet, and is held there
until the circuit is broken as hereinafter explained. The disengagement, of the
armature releases the switch, so that the motor rotates it until the circuit is broken
by the finger meeting its shunt on the switch, when the spring, beneath the
armature throws it up into engagement with the gear 19, encountering the tooth
_corresponding in-number--with-the-fingers, and-button operated, and stops the
rotation of the switch.
The lower end of the rod 25, (Fig. 13.) is pivotally connected to the
horizontal bar 26, the rear end of which is hinged to a bracket upon the casing
so as to permit--it to play vertically, and upon its outer end, I form a projecting
point, and beneath that a rounded shoulder as shown in Fig. 6, and a crank
of which 27, is the lower arm, and 28, the upper one, is pivoted upon this
shoulder.
Upon the shaft 20, adjacent to the gear. 19, I mount my multiple cam 30,
consisting of a piece of sheet metal of substantially the form shown in the drawings

page_text: (Fig. 8.); its periphery comprising a series of 10, cam faces and stops each upon
a radius of graduated increasing length, in regular succession, and for greater
perspicuity, I have numbered these cams: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, to correspond
with the numbers upon the buttons in the first, second, and fourth rows.
A lever 31, extends across the front of the frame 24; and one end thereof is
pivoted upon said frame, and provided on its inner face with a projecting bevelled
lug 31; as shown in Fig. 18, and this lug is under the cam and is always in
contact with one of its cam faces. Their joint operation is hereinafter described.
A display dial is mounted upon the front end of the shaft 20, (and also upon its
rear, end if desired,) to display in front and rear, and rotates with the switch, h,
being the unit dial; ', the tens" dial; ", the "hundreds". or dollar dial, and
the figures thereon, showing the amount of each purchase, are displayed through
openings 32, 33, Fig. 12, the opening 32, being a double one for showing the units
and tens upon these two dials.
Upon the top of each frame, I mount an adding dial, adapted to be rotated,
m, being the unit dial, m', the "tens" dial, and m", the "hundreds" or dollar dial.
Each dial has a hundred notches, or teeth, upon its periphery, and each tooth
is numbered from 1 up to 100.
An arm 34, Fig. 13, is erected upon the top of the frame 24, and is provided
with an outward projection at its top, upon which I secure a downward arm 35,
(Fig. 1, and 13) in which is an opening near its lower end, through which I read
the figures upon the adding dial; and above the centre with a reading aperture
for reading the figures upon the footing dial n; (or n', or ",) which is pivoted
between the arms 34, and 35.
A spring pawl 36, Fig. 1, secured to the arm 34,. and extending down and
engaging with the teeth of the adding dial (m, m', or m¹¹) prevents the backward
rotation of the dial.
A stud or pin projects from the rear face of the adding dial m, directly in line
with the tooth marked 100, in such manner as to engage with a tooth upon the
footing dial (see Figs. 21, and 22.). whenever the 100, on the dial m, comes
opposite the reading aperture or passes it. There are ten teeth on the edge of
cach footing dial, and those upon n, indicate dollars; and whenever the 100, pin or
dial in, engages with a tooth on dial n, and the dial m, is rotated past 100, to
show, 1, 2, 3, 4, 5, etc. such rotation will rotate the dial n, a single tooth, (or
figure) and change the number visible in the upper reading aperture.
A rod 37, Figs. 1, and 17, is pivotally connected at one end, to the lever. 31,
and at the other to the swinging bar 38, the inner end of which is pivoted upon
the shaft of the dial, (m, m', or m",) and 39, is a spring pawl pivoted upon the
upper end of the rod 37, and adapted to engage with the teeth upon the adding
dial.
Each of the dials is operated in the same manner, and as follows:-
:-
When I depress a unit button, say 4, I make a circuit contact of the spring.
finger 4, with the point making a circuit with the 4, unit wire, the union board
(unit 4, screw) and through the unit bunch or set of wires, to the electro magnet I,
drawing the armature 18, down from its engagement with the 0, tooth of the switch
gear 19, upon the end of the switch 12, thus releasing the switch rotation
mechanism; and then the spring 29, pulls down the bars 26, and the rod 25,
Figs. 1, 13, and 17, and this rotates the crank gear 22, which through the pinion 21,
rotates the switch 12, until the finger 4, shunts upon the shunt 4, which breaks the
circuit, and the armature flies up into engagement with the 4, tooth of the gear 19,
and stops the rotation of the crank gear, pinion and switch.
Simultaneously with the rotation of the switch, the multiple stepped cam is also
rotated, and this cam is normally in frictional engagement with the lever 31,
through the lug. 311, upon its inner face, the spring 42, operating to hold it up
yielding against the face of the cam, at the nought step thereon.
This rotation of the cam causes the steps 1, 2, 3, and 4, to successively bear
upon the lever, each one depressing, the left hand end of the lever, a graduated

page_text: distance lower than the preceding one, thus drawing down the rod 37, and the
swing bar 39, the pawl snapping from one tooth to another, as each successive cam
depresses the lever 31, until in this instance, when the switch stops, the pawl has
dropped four teeth upon the adding dial m.
This pawl, the lever, the cam, the switch, gear and pinion, and the crank gear,
remain in this position until the drawer which is now open, as above described is
closed.
The closing of the drawer compresses the ejector spring 17, brings the top of the
inclined bars 40, (Fig. 6.) secured upon the top of the back of the drawer, into
contact with, and they wedge under, the crank 27, which forces the rod 25, upward,
and this reversely rotates the crank gear, the pinion, the switch-gear, and cam,
back to the nought position, ready to be again operated, and the motor spring 29,
is again under full tension.
Simultaneously with this backward rotation of the cam and reduction of down-
ward cam pressure upon the lever, the spring 42, one end of which is secured to
the casing, and the other end to the lever 31, or bar 37, and which was strained
down by the depression of the lever, re-acts and raises the lever and pawl, and
rotates the dial m, the distance of four teeth, thus adding four upon the dial.
Also as the drawer closes, the straight bar 41, secured to the top of the back of
the drawer, and projecting backward therefrom, engages with and pushes back the
swinging bar 43, which is pendant from the lever 31, and as the spring 42, raises
the lever, the bar 43, will swing forward and stand upon the top of the bar 41, and
lock the lever 31, so that neither it, nor the pawl, can be lowered or depressed until
a button is operated, and the drawer is reopened.
When the forward rotation of the switch 12, the disk , is rotated, bringing the
figure 4, opposite the right hand end of the double aperture 32.
The operation of displaying and adding a "ten," by operating a button in the
second row, is the same as that of a unit, the ten figure being displayed in the left
hand-end of the opening 32.
In this mechanism the footing dial_n', is marked from 10, to 100, and the tens
adding dial is provided with a pin on the back side as in the case of the two
other adding dials m and m!, so that as soon-as-10,-tens-are-added-on to the dial-m³,
the dial n', will be rotated one tooth.
The operation of the " hundreds," or dollar mechanism, is like unto the unit
mechanism, the dial n', being numbered from 100, to 1000, so that when the
dial m, adds 100, the dial ", is shifted by the pin on dial m", as in the unit
devices..
It will be observed that-when the unit-dials have added up to $10.00 the
adding and footing dials start at one automatically; that when the "tens" dial
indicates $100, they start again automatically, dial m', at one, and n', at 10, and
that when the "dollars," dial indicate $1,000 they automatically start again at the
starting point, dial m", at one, and dial ", at 100.
"
When a double button is operated, the contact is first made on the unit side, and
starts the unit adding and display mechanism, and an instant later, the "tens
contact is made, starting the "tens" adding and displaying mechanism, and thus
almost simultaneously displaying both figures in the aperture 32.
In fact I can operate all three of the display dials and adding mechanisms
-simultaneously, or nearly so, and display, and add, units, tens, and dollars, by simple
operation of the unit "tens," and "hundreds," buttons, in such quick succession as
to be substantially simultaneous.
The alarm bell 44, is always rung, when any button is operated, by any ordinary
electrical means, or whenever the drawer is opened as may be desired.
It will be observed that when the nought button, on either row is operated, the
switch does rotate sufficient to display a nought, but nothing is added or done,
except to open the drawer, and sound the alarm.
As a guard against the surreptitious opening of the front of the casing, affording
access to the adding and footing dials, and to prevent any tampering with them, by

page_text: letting the pawl and spring out of engagement, and then turning them backward,
either before or after the abstraction of money from the drawer, I use the following
mechanism to indicate the number of times the front. of the case is opened by any
person.
Upon the inner face of one side of the casing A, and adjacent to the top thereof,
I mount a toothed wheel 45, and a pawl 46, engaging therewith, and this wheel is
provided with a full row of perforations 47, adjacent to its periphery.
At 48, I mount a bracket below the wheel, slotted to receive a push pawl 49, the
rear end of which engages with a tooth of the wheel, and is held in engagement by
a spring and the arm of this pawl extends outward far enough, so that the front
door of the casing, when it is being closed, will strike or bear against it, and push
the pawl in, and rotate the wheel one tooth.
A plate 50, with a slot 51, is secured upon the inner face of the case, having the
inner end extending over beyond the perforations 47, and it is perforated at 52,
which perforation coincides with, or is in line with each of the perforations 47.
This
This plate 50, covers a groove or recess cut in the inner face of the casing and I
secure the outer end of a spring bar to the outer face of this plate near its outer
end, so that the free end of this spring can play outwardly in this recess.
spring bar carries, on its free end, a pointed stud 54, and, between that and the
secured end, a wedging lug 53, both projecting from the same side or edge of the
bar; the wedge passing through a slot in the plate 50, and projecting inwardly
beyond the inner face thereof.
This bar is so located that the stud 54, will pass freely through any of the
perforations 47, as the wheel is rotated and when it so passes through, will always
enter the perforations 52, and when a paper disk 55, is placed upon the front of the
wheel and secured there by the thumb screw 56, a part of this disk will lie between
the inner end of the plate 50, and the face of the wheel, and so that the punch
stud 54, will perforate the paper each time it passes through the holes 47, in
succession.
A flat spring is secured at its upper end upon the plate 50, and projects down-
ward therefrom in such manner that its lower cud engages with a lug on top of
the pawl arm (see Figs. 10, and 16) and this spring is compressed by the closing of
the door which encounters the outer end of the pawl pushing the pawl inward, and
then, as the door is again opened, this spring throws the pawl outward again, the
distance of one tooth on the wheel and ready to be pushed in again, as the door is
closed.
It will be observed that the number of holes in the paper, will correctly indicate
the number of times the front door has been opened; and that it cannot be closed
without registering the closing by a hole in the paper.
The battery (not shown) is connected to the button 59, by the positive wire 60,
and the negative wire 61, in the ordinary manner, and as shown in Fig. 19, the
wire 60, is carried across, over to the binding screw 62, whence a branch conducts
a positive current to the contact fingers f,f", f, and this current when a
circuit is made by the operation of any button, is carried to the union board and
thence into one of the bunches, which carries the current to the fingers 11, and
through them into the peripheral cover of the switch, and gear 19, and so long as
the armature 18, is in engagement with this gear the circuit is broken, but when the
button is operated the armature becoming positive is drawn down into contact with
the negative pole of the electro magnet I, making the circuit there, and thence the
wire 68, conducts the current to the negative wire 61, leading to the battery, and
the wire 63, conducts a current to the electro magnet H, making a circuit there,
operating the armature to unhook it from the catch on the drawer, unlocking the
drawer, and the wire 64, conducts the current to a ground, here shown as the
wire 61, leading back to the battery.
The wire 65, carries a positive current to the bell mechanism 44, and the binding
screw 66, Fig. 19, and the wire 67, completes the circuit, by its connection to the
negative wire.

page_text: The binding post. 59, is of any ordinary construction.
The dotted line in Fig. 20, extending diagonally across the rotary switch
indicates a wire within, and insulated from, the outer casing, and extending across
each of the shunting openings therein, so that all of the fingers successively come
into contact with it, as the switch rotates, and the fingers which correspond to the
buttons operated will make a circuit with said wire, and shunt the current through
this wire, passing out through the rear end of the switch, and thence follow said
wire down to the magnet H. This shunting to the magnet H, is the same as is
shown in my United States Patent No. 358,645, in Fig. 4. for shunting the current
'from the switch to the magnet C, therein.
Having now particularly described and ascertained the nature of the said-inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1 The combination with a rotating multiple switch, and 'contact fingers
engaging therewith, and push buttons arranged in decimal sets, electrically
connected at will, to the fingers, of an electro magnet, and its armature adapted
to release the switch when the circuit is made by operating a button, and to lock it
when the circuit is broken by the rotation of the switch.
2: The combination with a rotary multiple switch, and contact fingers engaging
therewith; and push buttons arranged in decimal sets, electrically connected at will
to the finger of an electro magnet, and its armature adapted to release the switch,
when the circuit is made, and lock it when the circuit broken, by the rotation of
the switch, and a motor arranged to rotate the switch, when a button is operated.
3: The combination with the rotating switch, and a gear secured upon the end
thereof; and contact fingers, engaging with the periphery of the switch, of the
