COMPLETE SPECIFICATION.
A Cash Register and Indicator.
I, THOMAS CARROLL, of New Haven, Connecticut, United States of America,
Machinist, 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 :-
The chief object of my invention is to provide a cash register and indicator, in
which the simple operation of drawing open the cash drawer by means of a knob or
drawer pull, or series of knobs or drawer pulls of appropriate representative values,
shall accomplish the announcement and registration of sales and indicate the amount
thereof. The invention consists in the novel combination with suitable registry
and indicator mechanism arranged in the case or frame, of a series of handles, knobs
or drawer pulls exteriorly mounted upon the cash drawer, having operating con-
nections or rods individually guided and adapted to a limited independent movement
therein, and of novel motive mechanism carried on the drawer and adapted to
actuate the registry and indicator mechanism, and tripping mechanism corresponding
to the series of drawer pulls adapted to operatively connect the motive mechanism
of the drawer with the registry and indicator mechanism corresponding to the
drawer pulls, or combination of drawer pulls manipulated, as determined by the
initial independent action thereof. The invention further consists in the novel
drawer locking and releasing mechanism, and in the construction of parts, as
hereinafter more fully described and claimed.
The principle disclosed in my improved cash register dispenses with the use of
the ordinary system of keys and springs for propelling the drawer outward, its
opening being effected by the direct pull of a knob or series of knobs having a
slight travel relative to the drawer, whereby the locking mechanism is released and
the corresponding trips are caused to operatively connect the registry and indicator
mechanism with motive means on the drawer, which in its outward travel actuates
the registry mechanism, and indicates the sale, without blows upon keys, com-
pression of propelling springs, or violent darting motion of the drawer. The
number, combination, and values of the drawer pulls or knobs may obviously vary
indefinitely, according to the requirements of different machines. For instance, a
register adapted for use in a public house for keeping account of sales of gin and
beer, the prices of which are not subject to change, might comprise a series of three
or more drawer pulls representing the popular prices of said liquors in the locality
where the machine is to be used, each drawer pull having its own releasing, tripping,
registering and indicating mechanism. There would also usually be required
another drawer pull and its train of mechanism, for the sole purpose of opening the
drawer to make change, which knob would be labelled "No Sale or "Change,"
and would so indicate when called into use.
"
In a four knob register, the three knobs exclusive of the "no sale” knob, may
respectively represent the values of three half pence, three pence, and six pence, or
any other series of figures desired.
A cash register required to register sales of any amount from a half penny
upward to pounds, may comprise a series of knobs representing the following values,
viz. Halfpenny, one, two, three, four, five, and six pence; shilling, florin, half
crown, five shillings, ten shillings and pounds from one up to any desired amount,
each having an independent train of mechanism as aforesaid.

In the accompanying drawings forming a part of this Specification:
Figure 1 is a front view of a cash register and indicator embodying my
improvements, and of the class adapted to register amounts from one upward to any
desired amount.

page_text: Figure 2 is a vertical section on the line x, x, of Figure 5, showing the interior
mechanism in side elevation.
Figures 3 and 4 show the action of the tripping mechanism.
Figure 5 is a rear view of the machine with the back of the case removed,
showing the mechanism in rear elevation.
Figures 6, 7, 8 and 9 show details of the registering mechanism.
Figure 10 is a perspective view of a small sized cash register and indicator on
my improved system; adapted for sales of three half pence, three pence and
sixpence, the sides and top of the case being removed to show the mechanism, one
of the drawer pulls withdrawn, the cash drawer released ready to open, and the
corresponding tripping mechanism set to effect the operative connection of the
motive means and the registering and indicating mechanism.
Figure 11 is a view similar to Figure 10, showing the cash drawer partly opened,
with the trip operatively engaged with the motive means, and the corresponding
indicator tablet exposed.
Figure 12 is a horizontal section on the plane of the drawer pulls, with the parts
in the position shown in Figure 10.
Figure 13 is a vertical section in perspective on the line, z, of Figure 12, the
cash drawer being shown partly opened, the trip engaged with the operating cam in
the action of registering and throwing up the indicator tablet exposed by the last
preceding registration, on the point of being disengaged and dropped from view.
To simplify the description, as the difference between the aforesaid several styles
of cash registers relates wholly to the number of knobs or drawer pulls employed,
the various accompanying mechanisms being simply duplicated proportionately, I
will first describe a single set of mechanism, that is the mechanism pertaining to
a single drawer pull. Any set or train of mechanism in any of the figures or the
styles of apparatus shown may be taken as the subject of the description, except as
the parts are referred to as being in set, tripped, engaged, disengaged, raised,
lowered, open or closed positions, all of which are fully illustrated in the various
figures. And similar letters of reference denote similar or analogous parts of the
mechanism throughout the drawings, without regard to the various styles of
apparatus shown, or the different representative values of the duplicated sets of
mechanism.
Referring to the drawings A in Figures 1 to 5 inclusive, and A' in Figures 10
to 13 inclusive, designate the cash drawer, suitably arranged and fitted to slide in
the case or enclosing frame of the cash register, which is denoted by the letter B
in Figures 1 to 5 inclusive and B₁ in the Figures 10 to 13 inclusive. Exteriorly
arranged on the front of the drawer are the knobs or drawer pulls C, in a series of
fourteen in the class of register shown in Figures 1 to 7 and numbering four in the
smaller machine shown in Figures 10 to 13 inclusive. The drawer pulls are
mounted upon operating shanks or rods d which are extended through the drawer
beneath the till p², or cash receptacle proper of the drawer, and guided and adapted
to a limited travel or free independent movement therein.
Secured on the inner end of each rod or operating shank d is a head E, which
rests upon the rearwardly projecting base F of the drawer, and, in the aforesaid
limited travel of the drawer pull and its rod d, is adapted to slide thereon. The
drawer pull, rod d and head E thus comprise a single operating part, which is
normally held back or retained at the rearward limit of its travel, by a spiral
spring g, which is coiled around the rod; and compressed into the space between
the head E and the rear side of the cash drawer.
Directly forward and in the paths of the heads E is a corresponding series of
operating dogs or swing arms suspended from and fixed upon a shaft or arbor
arranged transversely of and adapted to oscillate in the case or frame suitably
journalled therein. A. latch i is secured upon the arbor near one end thereof and
adapted to swing with the motion of the arbor and the series of operating dogs
The latch is adapted to engage a suitable hook H on the drawer, when the drawer
is in closed position, thereby locking it shut. The weight of the latch and the

page_text: operating dogs is alone sufficient to cause the interlocking of the latch and hook as
the drawer is closed, and a suitable stop should be provided to prevent the latch
from dropping below its normal position whenever the hook is disengaged there-
from. A simple stud 31 inserted in the side of the case beneath the latch as shown
in Figure 13 is sufficient for this purpose.
The series of heads E normally support a corresponding series of vertical
rods or trips j, which are guided and adapted to slide freely in suitable trans-
verse guides, frames or bars; secured to the case. Each trip is provided with a
horizontal pin or projection which is adapted to rest on the flat upper surface of
the head E, thus supporting the trip in the elevated position, the trips being
arranged in vertical planes which lie immediately alongside of, or offset from the
planes of the heads E.
Secured upon the rearwardly projecting base F of the cash drawer, is a series
of cams corresponding to, and arranged just in the rear of the heads E, and
also in the sliding planes thereof, that is, each cam lies in the same plane as
the projection k¹ of the corresponding trip. The operating flanges 32 of the cams
are curved or inclined from a plane parallel to that in which the drawer moves, the
front ends thereof being the highest, and arranged flush with the upper surfaces of
the heads E and with which they are normally in juxtaposition.
In the operation of the parts already described, the functions of the drawer
pulls and their connections are to release or unlock the drawer and trip or switch
the aforesaid trips into operative engagement with the operating cams or motive
mechanism of the drawer, the trips being provided with driving projections or
shoulders and m respectively adapted for operating the registering and indicating
mechanisms by engagement with the levers or arms * and m' thereof, as herein-
after described. If any particular drawer pull is grasped and subjected to the
strain of an outward pull as shown in Figure 10, the spring g will yield, and the
rod d and head E will travel forward in their bearings, the head E thereby being
brought into engagement with the operating dog 2, which movement raises and
disengages the latch i from the hook H, thus unlocking the drawer, which is then
free to be opened by continued pulling upon the aforesaid knob or drawer pull.
The said independent initial action of the drawer pull withdraws the head E from
under the projection of the corresponding trip, which thereupon immediately
falls, the said projection dropping into the space thus created between the head E
and the corresponding operating cam k². The fall of the trip is regulated and
limited by the positions of the projections k³ and m aforesaid, which are placed
sufficiently above the levers or arms k and m', assuming the trip in its highest
position, to permit the trip to fall far enough to bring the projection or pin k³ into
position for the leading or highest end of the flange of the operating cam to pass
over it in the opening movement of the drawer. If desired, a projecting shelf k
may be provided on each head to arrest the fall of the trips, and the heads should
be recessed on a line with the shelf k, forming pockets 33 into which the pro-
jection may enter as the head E is retracted by the spring g, when the drawer
pull is released from the grasp in manipulating a combination of drawer pulls.
The tension of the springs g is very slight, and less than the force required to
overcome the friction and inertia of the drawer, therefore the drawer will not open
by the reactionary effort of the spring after the release of the locking mechanism,
nor until additional force has been brought to bear upon it, sufficient to overcome
the aforesaid friction and inertia. Also the parts may be proportioned and adjusted
so that in the initial movement of the engaging heads, the trip will drop just
before the disengagement of the latch and hook takes place. Therefore any
desired combination of drawer pulls may be manipulated, and the corresponding
trips switched into operative relation with the operating cams before the drawer is
unlocked, or, if the drawer is unlocked in the process, the latch and hook will
re-engage, if the pull upon the knob is not violent. The fall of the trip may be
accomplished by gravity alone, or if desired, a spring pt may be arranged to act
downward on the trip to render the action more certain. When by the independent

page_text: initial action of a drawer pull or a combination of drawer pulls, the cash drawer
has been unlocked, and the corresponding trip or trips switched into operative
relation to the motive mechanism, as shown in Figure 10; continued pulling upon
the last drawer pull manipulated will draw out or open the cash drawer. In such
motion of the drawer the operating cams k² will engage such of the pins kas
have been tripped by initial movement of the drawer pulls, and will actuate said
trips downward, as shown in Figures 11 and 13 in which the mechanism of the
three half penny drawer pull is shown in operation. Such downward movement of
the trip will actuate the lever k of the registry mechanism, by engagement of the
driving projection therewith, and register the action as hereinafter described.
The pin m will also engage and depress one end of the lever m' thereby throwing
up the opposite end thereof and the corresponding indicator tablet, as hereinafter
described.
The restoration of the trips to their original or normal positions after the cams
have passed over and off from the projections is in part effected by springs p
coiled around the trips and adapted to be compressed under the pin 35 therein, as
the trips are forced downward by the cams 2. The adjustment of the said springs
is such that they offer no resistance to the initial drop of the trip, but will normally
hold the trips in about the same position as they would be supported by the
shelves k. At that height the cams readily pass under the pins k¹ of the trips on
the return or closing movement of the drawer, as shown in Fig. 11, by the relation
of trips and cams of the three pence, six pence and "no sale" drawer pulls
thereby forcing the trips up to place on the heads E. by impact of the pro-
jection with the upper surfaces of the flanges of the cams. Also, it will be
seen that said springs will support such of the trips as are not disengaged by
manipulation of the drawer pulls, and prevent them from dropping too far after
the cams have passed from under them, for it will be understood that in the opening
movement of the drawer the cams must slide under all the projections k¹ not
previously tripped into position to be engaged by the flanges of the operating cams.
The pins 35 in the trips engage the levers to restore them to their normal
position, on the upward travel of the trip.
The indicator mechanism is duplicated for each knob or drawer pull, the
representative value or number of which is identical with the particular indicator
tablet pertaining thereto. The tablets are exposed by means of the opening action
of the drawer, as follows, reference being had particularly to Figure 11, in which
the three half pence tablet is shown exposed and retained in place, and Figure 13,
in which the said tablet is shown near by, raised into full view, and the three pence
tablet, supposed to have been raised by the last preceding sale, is shown in the act
of being dropped from the exposed position, as hereinafter described.
As the trip is lowered by the action of cam through the outward movement
of the drawer, a pin m on the trip engages and depresses one end of a lever m' hung
on the arbor m10 in the case. The opposite end of said lever is thereby raised, thus
elevating the rod m* attached thereto, and adapted to slide vertically in the
guides m, whereby a suitable indicator tablet m² on the upper end of the rod m' is
raised and exposed to view through the slots m³ in the case. The said indicator
tablet will be held in such raised position while the cam is in engagement with
the pin at the lower end of the trip, during which interval the spring hook n' on
the base F successively engages, swings and releases the lower end of a lever n
depending from an arbor n³ which carries a series of pawls or hooks n' corresponding
in number to the number of knobs or handles of the drawer, and each adapted to
engage a pin n on the particular lever m¹ which it corresponds to or is associated
with. Such engagement takes place when the pin n is first raised, the lever n²
being actuated by a suitable weight no on the arbor n³, but the engagement is not
then permanent, owing to the subsequent swing of the lever by contact with the
spring hook n as hereinbefore explained. Meanwhile however, during the vibration
of the lever, the indicator tablet is maintained in elevated position by the
engagement of the cam with the pin k' of the trip j, and before the said cam

page_text: has passed entirely off from the pin k¹, the lever n² will have been released by
spring hook n and swung back to the normal position shown in Figure 2, and the
hook or pawl n' will have swung back and re-engaged the pin n on the lever m',
whereby the indicator tablet will be retained in the elevated and exposed position
until the succeeding opening movement of the drawer, the spring hook n' yielding
and passing under the lever n' on the return or closing movement of the drawer.
But it will be seen, that owing to the vibration of the series of hooks or pawls n¹
caused by opening the drawer, the indicator tablet or tablets left exposed by the
preceding opening movement of the drawer will be released and allowed to fall out
of sight, leaving only the new series of tablets which are exposed by such opening
action of the drawer. The spring hook n is also adapted to engage a spring
actuated lever n carrying a hammer p, adapted to strike a bell pl in the case, as
the drawer is opened, thus announcing the action. The cavity or till p² in the cash
drawer is set sufficiently back from the front edge of the case to prevent access
thereto until in the movement of the drawer the cam k has passed entirely
over the pink and thus operated the registering, indicating, and announcing
mechanism.
The method of registering sales by means of my inproved cash register is as
follows: On each of the trips; near the upper end thereof, is a pin or projection k³
which in the depression of the trip by means of the cam 2, is adapted to engage
and swing an arm mounted on an arbor which supports a series of registering
tape reels 7. Each of said arms has a hooked pawl pivoted thereto, and adapted
to engage the teeth of a suitable ratchet on each tape reel l. The said ratchets
are held against backward movement or slip, by the retaining pawls hinged on
the horizontal bar in the case. Rolls, corresponding in number to the said
tape reels and hereinafter more fully described, are arranged in revolving planes
corresponding to the revolving planes of the reels, and adapted to receive suitable
tapes of strong ribbon or other suitable material, coiled thereon, the opposite
ends of the tapes being attached to the tape reels . The tapes are graduated and
cach bear a series of numbers arranged in arithmetical progression having the
number or representative value of the corresponding drawer pull for the lowest
term and also the common difference of the series, and ascending from the ends
attached to the reels. That is, starting with the number of the knob or drawer
pull to which a given tape pertains, the series of numbers will comprise the
multiples of that number in their numerical order, as for instance the tape of the
penny drawer pull in Figure 1 will be numbered 1, 2, 3, 4, 5, 6, 7, and so on, up to
any desired number. The tape of the three penny drawer pull either in Figure 1
or Figure 10 will be numbered 3, 6, 9, 12, 15, 18, 21 and so on upward.
The tape
pertaining to the sixpenny drawer pull will bear the numbers 6, 12, 18, 24, 30, 36, 42
and in that order up to any desired limit.
In the operation of the registering mechanism, all the tapes are first set at zero,
by means of the mechanism hereinafter described, the zero point or line being
preferably indicated by means of a horizontal bar fixed transversely of the case,
over and adjacent to the tape reels 1. Said bar facilitates the reading of the tapes,
when the interior of the case is exposed to view by the removal of a portion of the
It will be seen from
top or cover thereof, in any ordinary or suitable manner.
the foregoing description, that if the cash drawer be opened by pulling one of
the drawer pulls, the tape pertaining to such drawer pull will be ratcheted upon its
reel 1, one division, bringing the number next succeeding zero up to the reading bar
and into view, thus registering the salc. And successive openings of the cash
drawer by pulling the same knob will successively bring the numbers of the tapes
in their order up to the reading bar r, also throwing up the corresponding indicator
tablet. It will be understood that the mechanism described, with the exception of
the latch i, levers n² and n³, the weight 70 and spring n being duplicated for each
knob, the manipulation of a combination of knobs, of various denominations will
register amounts which may be read in a denominational series. as pounds, shillings
and pence. Thus the manipulation of the one pound knob, the five shilling knob,

page_text: and the three penny knob will register the following amount and indicate it as
written, viz. £1, 5s., 3d. But if knobs of the same denomination are pulled in
combination, their values must be added, as for instance, the withdrawal of the
three half pence knob and three pence knob in the machine represented in
Figures 10 to 13 would register and indicate four pence half penny, which is the
sum of three and one and a half.
.
The collective readings of all the tapes gives the sum of all the sales subsequent
to setting the mechanism at zero. The indicator tablets m² are numbered to
correspond to the values of their respective knobs, and therefore any combination
of them will correctly designate the amount which tallies with the corresponding
combination of knobs. It is immaterial in registering combination of numbers
which knob is manipulated first, or whether they are pulled singly or together.
To insure the convenient and accurate setting of the tapes at zero, I provide
novel mechanism as follows: The tape rolls are placed between friction collars l
fitted on the rectangular arbor 2, and sufficient frictional resistance is imposed on
the rolls by means of a spring or other suitable means, to prevent the rolls from
turning freely on the arbor. Thus while the rolls will revolve on their collars, as
the tapes are ratcheted from them on the reel I, they will normally remain fast on
their arbors, and may be turned backward therewith when the pawls are raised
from engagement with the ratchets 12 and 1. Any desired suitable means may be
provided for turning the said arbor for the purpose of winding the tapes on the
rolls thereof. Thus the arrival of a roll at zero in no wise prevents the winding
of the rest until all are wound.
Figures 6, 7 and 8 show the construction of the tape reels 1, which are hollow, or
recessed as shown and each provided with an internal perforated projection t
adapted to support and guide a pin which when the tape is being set at zero,
drops down below the periphery of the reel and engages the guide j' thereby always
accurately stopping the reel at a given point or zero mark. But as the tape is
wound upon the reel the said pin is thereby pushed within the reel by contact with
the tape, offering no obstruction to the uniform winding of the tape. Each pawl l' is
provided with a projection t2 overhanging the pawl, whereby by lifting the said pawl
by means of an eccentric rod or cam arranged underneath the pawls horizontally
of the case the entire series of pawls may be simultaneously disengaged from the
ratchet and the tape reels thus left free to be turned backward as the tapes arc
wound upon the rolls in resetting the mechanism.
