Improvements in Cash Receiving, Registering, and Indicating
Machines.
1, JEROME JOSIAH WEBSTER, of 48 Green Street, in the City of Northampton,
County of Hampshire, and State of Massachusetts, United States of America,
Inventor, 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 :--
This invention relates to cash indicators and registers and consists in the devices
and combinations hereinafter described and claimed and which have for their
object to indicate on both sides of the machine the amount registered by a single
operation of the machine; to retain the indicating numbers exposed to view after
any operation of the machine until the next operation thereof; to prevent the
simultaneous depression of two or more keys; to prevent a partially depressed key
from returning to its normal position until after its complete depression; to register
by the depression of a single key, units on one registering wheel and tens on
another registering wheel in a series of registering-wheels, each adapted to
register ten to cause, by a complete revolution of any wheel, the wheel registering
numbers of the next highest denomination to make one-tenth of a revolution; to
enable, in such a series of registering wheels, each of said wheels to be operated
independently, to register numbers of its own denomination and also to operate the
wheel that registers numbers of the next higher denomination and to retard the
operation of the registering-wheel of the higher denomination due to the action of
the registering-wheel of the next lower denomination until its independent
operation has been completed; to keep the drawer normally locked and to prevent
it from being opened except by the operation of the keys and to prevent the keys
and the indicating and registering mechanism from being operated when the drawer
is open.

The case A consists of a lower rectangular part a in which slides a till or
drawer D, the table a¹ or top of the part a supporting the operating mechanism of
the indicator and register and an upper portion which conceals said operative
mechanism the drawer when released is caused to protrude from the case by a
drawer opening spring d, the above named parts being of any usual construction
except, that the upper part of the case is preferably shaped to conform partially to
the actual requirements of the space occupied by the operating mechanism."
The keys K turn upon a fulcrum-rod & supported by two or more brackets or
posts secured to the table a¹ of the, case A in substantially the usual manner.
The keys, as in other indicating machines, may be arranged in convenient groups,
one to be employed in registering and indicating cents, another group to be used
for registering and indicating dimes or dollars and so on, the keys being numbered
to correspond to signals which are brought into view by the depression of the keys.
The keys K all have a uniform range of motion, and in the drawing are numbered.
from five to,ninety-five in multiples.of five, the key,K' at the extreme right being
intended not for registering purposes but merely to unlock the drawer, sound the
alarm and return the signals to zero, as hereinafter more fully explained.
Every other key K (beginning at the right and excluding the non-indicating
key K) is marked 5 or some number represented in part by a 5 in the units place
and the alternate keys are marked 10 or some multiple thereof.
The rocking-plate P is provided with arms p through which the fulcrum rod is
passed, the plate extending over all the keys of the group and in its normal
position being arranged just above the keys of said group, so that the depression of
any key to its fullest extent, will cause said rocking-plate to turn upon the fulcrum-
rod k, a spring p² restoring the rocking-plate to its normal position when the key
in
has returned to its position. On the under side of the rocking-plate P,
brackets, one of said brackets being a rib which extends along the left
side of said rocking plate, slide nine actuating and stop bolts p, arranged in a
common plane, said bolts being parallel both with the top of said rocking-plate and
with the fulcrum-rod & the left ends of these bolts p being held flush with the left
side of said plate P by.springs attached to said bolts and to the under side of
said plate and by stops or shoulders pon said bolts, which limit the motion of said
bolts to the right; although as above stated the complete depression of any key
rocks the rocking-plate, this is not the first action caused by a partial depression.
Each bolt is provided on its under side with two inclines p p secured thereto,
which are essentially alike and are placed at the same distance apart from each
other as two adjacent keys K and above a pair of keys one of which is
marked by a number which is 10 or a multiple thereof and the other by a number
greater than said multiple by as 10 and 15, 20 and 25, or 90 and 95,-the
inclines being so arranged that the depression of either of the keys of such
pair and the raising of the rear arm of said keys against one of the inclines will
cause the bolt to which said inclines are secured to project from the left of the
rocking-plate an equal distance, and one of the bolts will thus be caused to
project from the rocking-plate by the depression of any key numbered higher
than 5, each of the bolts when thus, enters a horizontal slot in the right side of
a registering lever L arranged at right angles to said bolts and turning from a
horizontal fulcrum parallel to the fulcrum-rod k back of said keys, said slot being
long enough to admit the ends of all of said bolts at a time and wide enough
vertically to admit them freely but without allowing them any vertical play therein.
It will be seen that slightly depressing two non-adjacent keys will cause two bolts
to enter the slot in the registering-lever L, but, the rocking-plate and registering-
lever having their fulcrums at some distance from each other and rising in opposite
B

page_text: directions, and the bolts lying in the same horizontal plane and fitting said slot, it
is evident that neither the rocking-plate nor the registering-lever can be raised
when two bolts are in the slot and therefore two corresponding keys arranged
under the rocking plate cannot be completely depressed. It follows that only two
keys of the same pair, that is, two keys which operate the same bolt, can be
simultaneously depressed to their fullest extent, and two keys of the same pair
cannot be depressed, except by intention because, as will be seen in Fig. 2 every
two keys of the same pair are arranged in different ranks, the keys denoting 10 and
multiples thereof being in the front rank, and the keys denoting 5 and multiples
thereof being in the rear rank, and the buttons of the two ranks are some distance
apart. It will appear hereinafter that when two keys of the same pair are depressed
the indication and registration; due to the key bearing the higher number only will
be accomplished.
For anything that appears thus far the depression of either of the keys of the
same pair would accomplish the same results and so far as their acting upon the
registering-lever is concerned, this is true, the keys of each pair from right to left
moving the registering-lever to a greater are than the keys of the pair next to the
right thereof, because the bolt operated by the keys of the lower pair is nearest
to the fulcrum of the rocking-plate and therefore swings through the smallest arc and
also acts upon the registering lever at a greater distance from the fulcrum of said lever,
the bolts operated by the successive pairs of keys being placed at greater distances
from the fulcrum rod as the successive pairs are farther from the right of the
rocking-plate, as shown in Fig. 8. The indication and registration due to the
movement of the registering-lever are always 10 or multiples thereof, other means
hereinafter described being used to indicate and register 5 and odd multiples
thereof. To the registering lever L concentric therewith, is secured a toothed are
or segmental gear which engages a mutilated pinion turning loosely on
stationary horizontal shaft ", (see Figs. 1, 4, 10-16, 18-20, 22-24) and secured
to a transfer wheel or gear 1. A pawl is pivoted on the side of the transfer
wheel and engages the tooth of a single-toothed ratchet-wheel, which,
together with the mutilated or long-toothed ratchet wheel and the cam-
wheel, is rigidly secured on the hub of the indicating wheel 1, so that
depressing a key and raising the registering-lever causes all said wheels 1222
to be rotated together. The indicating wheel I is provided on its face with two
sets of figures from 0 to 9 inclusive (see Figs. 2 and 3) the same figures of
the two sets being diametrically opposite each other, that is, one 0 is opposite
the other and one 9 is opposite the other 9, and so of the intermediate figures,
and said wheel I in its normal position or before the machine is operated displays
through each of the windows a³ in the case A the figure 0 at the front and
back of said case. When any key numbered 10 or more is depressed the indicating
wheel is turned to display at said windows a figure which is the same as the
figure which occupies the tens place on said key, thus; if the 10 or 15 key is
completely depressed, the figure 1 appears at the windows, if the 80 or 85 key
is depressed, the figure 8 is displayed, and the indicating-wheel is held from
returning to its normal or 0 position by a pawl which being pressed by the
spring engages the proper tooth o, of the ten teeth of the mutilated or long
toothed ratchet-wheel the pawl, the transfer wheel which carries it and the
pinion returning to their normal position when the key is let go and the rocking-
plate and registering-lever returned to position.
je
The units indicating-wheel consists in effect of two opposite sectors of a
wheel, the face of each sector showing a 0 and a 5 the diametrically opposite
figures being alike and 0 being normally displayed at each of the windows as a in
the front and back of the case. Sliding in brackets or ribs p³ p10 at the opposite
sides of the rocking-plate, is a units bolt provided with as many inclines or
cams p¹² as there are keys denoting odd multiples of 5, these inclines pz being
arranged over said keys so that when any such key is depressed and its rear arm
strikes said incline, said units bolt is moved preferably, in a direction opposite to

page_text: that of the bolts, p³, above described, in order to equalize the pressure of the
inclines, p, p, of the keys. The units-bolt, p", is provided with a backward
projection, p, which when said bolt is moved, as above described, is brought under
a lever, pivoted at its front end, at 2, to the frame of the machine and at its
rear end connected by a link, 10, to the units-indicating-wheel, back of its center,
so that when the rocking-plate is raised by the complete depression of a key marked
with any odd multiple of five, the projection, p³, strikes the lever, 8, and turns the
units indicating-wheel far enough to display the five marked thereon, thus: when
the key marked 85 is depressed the 8 is shown on the tens-indicating-wheel, I, and
the 5 on the units-wheel, 11.
The tens-indicating-wheel, I, is prevented from turning too far and thereby
showing too high a number, by a bell-crank lever, ", which turns on a horizontal
pivot,, the upper end of said lever,, having a rearwardly-projecting tooth, ¹³,
which enters one of a series of notches, ", in the face of said wheel, when the
rocking-plate strikes the lower arm of said lever, and is disengaged from said
notch,, when said plate falls, by a spring, ", wound around said pivot and
pressing upon said lower arm, there being as many notches, 14, as there are figures
on one-half of said wheel, I, that is ten notches.
The indicating wheels, I, I, continue to show the indicating figures, after the
same are once displayed, until another depression of the same or another key. The
first effect of such second depression is to allow both of said indicating wheels to
return to their normal position, that is, to the position in which 0 is indicated at
each of the windows.
Until the tens indicating-wheel I is so restored to the 0-position, the registering-
lever L is prevented from operating by the unlocking-lever Fig. 11 which turns
on the horizontal rud 18, supported on the frame of the machine, the lower end of
said unlocking-lever being forced by the spring 18, applied to the upper end thereof
backward over a lateral projection whenever the registering-lever is at its lowest
position, but when said tens indicating-wheel is in the 0-position, a cam projection/*
on the cam-wheel (said can-wheel being as above stated, secured to the hub of
the tens indicating-wheel) presses against the upper arm of said unlocking-lever
and turns the lower end of said unlocking-lever forward out from engagement with
the projection and allows the registering lever to rise.
Figure 11 shows the tens-indicating wheel, I, in its 0-position its cam, 2, at this
time having moved the lever, 20, so that its lower end is out of engagement with
the lateral projection, 7, of the registering lever, L, which is now free to he
operated.
to
The retaining of the indicating-wheels in the indicating position is accomplished
by means of pawls one of which, engages the teeth of the long-tooth
ratchet-wheel as above stated, see Fig. 12, and the other, 10 of which engages a
two toothed ratchet secured to the hub of the units indicating wheel 11, these
pawls being held in engagement with their respective ratchets by a spring o
shown in Figures 9, 12, 13 and 14 supported on the frame and pressing against
both of said pawls. The pawls are pivoted on the above named rod 8 which
also serves as a fulcrum for the pawl-lever and unites both of said pawls
said pawl-lever by a rule joint so that a forward motion of the lower end of said
pawl lever causes the upper ends of both of said pawls to be thrown out of engage-
iment with the teeth of their respective ratchets. The rear end of each key K K'
is provided with a projecting finger Figures 1 1 and 4 which when the key is
depressed rises against a releasing plate J Figure + (or a series of rigidly connected
fingers, one for each key would accomplish the same purpose), rigidly secured to
the releasing-rod which extends at the back of all the keys and turns in
brackets secured to the table a' there being secured to said releasing-rod
lever J Figures 1 and 4 bearing a leaf-spring j which curves upward and backward
and has at its upper end a lateral ear j' (see Figs. 2, 124 and 12B), which strikes a
horizontal stud projecting from the lower end of the lever and throws said
lower end forward and allows said indicating wheels I 1 to be returned to their
a

page_text: to
normal positions by coiled springs secured to said wheels respectively and to
the shaft on which they turn, the long teeth of the ratchet striking the pawls 16
and preventing said wheels from passing the 0-points in their return motions. As
soon as the car j' of the spring passes above the stud the pawl-lever is free to
be swung backward to position, and against a stop 3 by a leaf spring Figures 9
and 12 secured to the frame of the machine. The post on the lever J'is merely
support the upper end of the spring when said spring is pressed up against the
stud said spring being quite light to allow said stud to move it aside when the
releasing-plate and said lever J' are returned to position. To briefly summarize
the operation of the last described parts: the pawls, and 16, hold the indicating
wheels in their indicating position after each operation and until the next operation
of the machine, and when these pawls are in engagement with the ratchets, and 17,
and the next key is operated the spring-part,, through its lateral and downwardly
inclined projection, j, as it moves rearwardly, for instance, acts as a cam against
the under-rear surface of the stud, 20, exerting a forward pressure thereon to swing
the pawl-lever, 19, to release the pawls so that the indicating wheels, i and, may
come back to their 0-positions. The part, j, just after the beginning of the new
registering operation passing from engagement of the then swung lever, 19, permits
the said lever to move to bring the pawls again into engagement with the ratchet
of the indicating wheels. When the key and releasing parts, J, 2, and,resume
their normal positions the part, j, snaps past the stud, 0, without breaking the
then engagement of the pawls with the indicator ratchet, the breaking of such
engagement not being accomplished until another operation by a key-lever repeating
the actions described. A T-shaped lever J2 is secured to the releasing-rod (see
Figs. 1, 1, 4) and turns with it and a spring j³ supported from the inside of the
back of the upper part a² of the case A is provided with a catch, which, when
the said releasing-plate is raised by the depression of a key to its greatest height,
reaches over the top of said lever J2 and holds said releasing-rod from returning
to position until an arm projecting downward from the rocking-plate P (Fig. 14)
in being restored to position strikes an arm which projects from said releasing-
rod below said arm p. The registering is accomplished simultaneously with the
indicating, the registering of tens by the transfer-wheel engaging an inter-
mediate gear which engages the registering gear, Figure 2 the latter carrying
a pawl which is kept by the spring in engagement with a ten-toothed ratchet
concentric with said registering gear and with the tens registering-wheel R and
rigidly secured to the latter, the ten figures of registration (0 to 9) being marked
on the face of said registering wheel R which together with the units registering-
wheel R¹ is concealed by the case which can be opened only by a key carried by
the proprietor or some trusted person (see Figs. 1, 2, 3 15-20): The units
registering-wheel R' is similar to the tens registering-wheel R in having secured
to its.hub a concentric ratchet which as shown in Fig. 15 has however, only four
teeth (but may have a larger even number of teeth) and has on its face only the
figures 0 and 5 (half as many of each as there are teeth in the ratchet) alternating
with each other, the units registering wheel being actuated by a pawl carried by
a plate or disk concentric with said wheel R and ratchet r, said pawl 8 being
held in engagement with said ratchet by a spring 10 also secured to said plate,
and said plate being rotated at each movement of the units indicating-wheel an
angular distance equal to the angular distance measured by a single tooth of the
ratchet, that is, as these parts are represented in the drawing 90°, a stud on
the pawl-plate being connected by a link Fig. 1 to one of the arms of
the units-indicating-wheel I', the pawl drawing back over the teeth when
said units-indicating-wheel returns to 0 from 5 and, at each forward movement
of said units-indicating-wheel from 0 to 5, turning the ratchet and units-
registering wheel one tooth. When the units-registering wheel moves the
angular distance measured by two teeth of the ratchet ten must be
registered and this is accomplished by rotating the tens registering-wheel R
one tooth of its circumference at every alternate forward movement of the units

page_text: A
registering-wheel R', a cam-wheel (Figs. 2, 3, 17 and 24) is secured to the left
end of the units-registering-wheel or cast in one piece with it and concentric there-
with, said cam-wheel having two cam surfaces, each extending half way around
said cam-wheel and dropping suddenly to the other cam surface thereof.
cam-lever is rigidly secured at its lower end to a rod 6, extending from the left
side of the units-registering-wheel to the left side of the tens-registering-wheel and
supported and turning in a bracket Fig. I secured to the inside of the back of
the case A. The said can-lever is provided with a projection which bears
against the face of the cam-wheel 2 being held thereto by a spring, so that, at
each half revolution of said cam-wheel, or in other words, at every other time
the units registering-wheel makes a forward movement, said projection runs off
the end of one of the cam surfaces of said cam-wheel and allows said cam-lever 7.16
and a pawl-lever, also secured to the rod, and a pawl 20 pivoted to the upper
end of said pawl-lever and engaging a ten-toothed ratchet secured to the
tens registering-wheel concentrically therewith, to move forward a sufficient
distance to rotate said tens-registering wheel one-tenth of a revolution. But
obviously this is not all that is required, because, to illustrate, if the units-
registering-wheel already registered 5 and it were desired to register 85 the sum
total of the two registrations should be 90, that is, after the second registration,
the units-registering-wheel should show a 0 and the tens-registering-wheel should
show a 9, but, without other mechanism than that above described, the complete
depression of the 85 cent key would cause the tens-registering-wheel to register 8
and moving the units-registering-wheel the value of one tooth would cause said
units-registering-wheel to register 0, so that the sums of the two registrations
would appear to be 80 instead of 90, owing to the fact that the action of the units-
registering-wheel on the tens-registering-wheel would be simultaneous with the
independent action of said teus-registering-wheel due to the action of the
registering-pawl ² and gear r¹. The 8 is therefore registered simultaneously with
the movement of the units-registering-wheel froin 5 to 0 and the action of the
pawl and the pawl-lever is delayed until these registrations have been made,
said cam-lever being provided with a spring arm which, in the forward
movement of said cam-lever and pawl-lever, strikes against an annular flange 2 of
the registering-gear, », and thereby prevents said pawl, 20 from operating the
tens-registering-wheel R until said tens-registering-gear, r, is restored to position
by the dropping of the registering-lever, L, said flange, having a slot, 25,
which, when said registering-gear is so restored to position, allows said spring-
arın, 3, to pass within the flange and the pawl-lever, r, to be drawn forward by a
spring,, above-named, and by its pawl, 20, to turn the tens registering-wheel
one-tenth of a revolution.
The sides of the slot, 28, are rounded to allow the spring-arm to enter the slot
more readily.
The inner edge of the flange, 24, is bevelled as well as the adjacent surface of
the free end of the spring-arm, 5, as shown at the left of Figure 24, where the
registering-wheel, R³, represents a registering-wheel adapted to register hundreds
or dollars, but which is a mere duplicate of the wheel, R, representing the
flange on the dollar or hundreds registering-gear, 27, and 8, representing the
corresponding spring-arm and said last-named flange and spring being represented
partly in section to show their bevelled surfaces above referred to.
In the way
indicated, the registering devices may be duplicated indefinitely, and the excess of
ten be carried from one registering-wheel to the registering-wheel of the next
place above.
To compel the complete depression of the keys, K, and therefore a full indication
and registration of the proper amount, each key is provided with an upward
projection, ³, having on its rear edge a rack, k, the teeth of which point downward
and engage a swinging pawl, 4, or wing, (Figs. 1 and 1^), which extends at the
back of all the keys of the machine and is pivoted near its lower end on opposite
sides at ; and has down-hanging arms, A, each of which rests upon a leaf-spring, ³,

page_text: supported at its rear end on the base or table, a¹, and provided at its end with a
V-shaped rib, ko, so that when the lower edge of said arms are at the back of the
rib, ko, the upper edge of the pawl, 4, is thrown forward to engage the racks, k,
and when the lower ends of said arms are in front of said rib, , said pawl is held
out of engagement with said racks. The pawl is thrown out of engagement with
the racks by the backwardly projecting ends of the down-hanging arm, p6, of the
rocking-plate, P, striking the upper part of the pawl, 5, when the key is fully
depressed, and thrown into position for engagement again by said projecting ends
of striking the lower arms of said pawl, . The pawl, 5, is also provided with
a shoulder, ; which, when the keys and rocking-plate are in their normal position,
reaches over the rear edge of said rocking-plate and prevents the rising of the
same, the upper ends of the projections 3 being cut away at A", to allow the pawl
to fall forward far enough for this purpose. When any key is first depressed,
therefore, it throws out a bolt into the slot of the lever L, as above described,
and does not throw back the pawl, k, until the recessed part, k", has risen above.
the top of the pawl by which time the bolt has been projected to its greatest
extent.
The rocking of the plate P, also releases the drawer and allows the spring, d', to
throw the drawer, D open. A bell-crank lever, d³, is pivoted to a bracket d
secured to the under side of the top of the lower part, a¹, of the case, A, and its
lower nearly horizontal arm, d, is provided with a hook, d, adapted to reach over
a catch, o, secured to the top of the drawer or to a partition therein, said catch
and hook being bevelled, as shown, to allow the catch to be shoved under said hook
and to be retained by the hook dropping down in front of said catch, and the
nearly vertical arm, d, of said lever reaches up through the top of the part, a, of
the case and terminates in a hook, 8, and bevelled end, d", said hook being adapted
to be engaged by the hooks, p", secured to the rocking-plate, P, and reaching down
(see Figure 1) below the top of the hook, d, when the drawer being open, the
horizontal arm, d, of the lever, d, is thrown downward and the upper arm of said
lever is thrown forward. When the drawer is closed, the hooks are disengaged and
the lower end of the hook, p", when the rocking-plate rises, strikes the curved
part, of the lever, d, above the hook, d, and raises the horizontal arm of said
lever and releases the drawer.
When the rocking-plate falls the drawer being open, the hook engages the lever
and prevents the rocking-plate from rising and therefore prevents the keys from
being operated. The hook p¹, is adjustable laterally in a slot, p1, in the rocking-
plate, to allow said hook, p, to be moved out of range of the hook, d, of the
lever, d, and to allow the keys and rocking-plate to be operated when the drawer
is open,
said hook, p, being held by a shoulder, pl, on said hook, p, and thumb-
nut, p, turning on the upper end of said hook above said rocking-plate so that
loosening said thumb-nut allows the hook, p", to be adjusted as above stated.
When the rocking-plate, P, is raised to highest position an alarm is sounded
simultaneously with the opening of the drawer, D. A bracket, h, is secured to the
rod, , and supports a gong or small bell, B, and pivoted below the bell, B, at b², is
a lever, 61, in such a position that the free frout end of said lever, 61, will be raised
by the rising of the rocking-plate, but will slip off from said rocking-plate about the
time when said rocking-plate reaches its highest position and will be carried down
again by a spring, 6", hereinafter described (see Fig. 2) until the hammer arm, bª,
strikes against a stop, &, projecting laterally from said bracket . The said hammer
arm 7, has an elastic wire-arm, B, and striker, 6, and is pivoted on the same
pivot, 2, as the lever 6', and is provided with a laterally projecting stop, 68, which
fits into a recess in the arm 4, which is the tail end of 6. Hence when the front
end of the lever b, is raised by the rocking-plate, the bell hammer arm b', is moved
with it, carrying the striker, , away from the bell, B, and, when said front end of
said lever, &, slips off from said rocking-plate both levers are restored to their
normal position by said spring, 10, and being suddenly checked by the lever
hammer arm 6 striking the stop, 68, the momentum of the striker, 6°, carries it

page_text: against the bell, the elastic arm, 68, yielding for that purpose and immediately after
withdrawing the striker from the bell. When the rocking-plate falls, the front
arm of the lever, b', yields, to allow said plate to pass said lever, and is then
restored to position by the spring, 6, which is weaker than the spring, 610, and at
one end is secured to said pivot, 63, and surrounds the same and with its other end
reaches under the front arm of said lever b¹.
