Improvements in Cash Indicators and Registers.
I, JOHN SHARPE, of 561/2 King Street East, Toronto, in the County of York,
in the Province of Ontario, Canada, Manufacturer, 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 Improvements in Cash Indicators and Registers
patented to me in Great Britain and Ireland under Number 18017 on the 12th day
of November 1889, and the object of the invention is first, to simplify the
construction and operation of my cash indicator and register-secondly-to provide
further safe-guards whereby inaccurate sums may be prevented from being
registered and the machine may be prevented from being tampered with by
dishonest persons, so as to falsify the total amount registered at any particular time
and-thirdly to provide an improved means whereby the opening of the drawer
may be controlled, so that it can only be slid out upon the operation of one of the
keys of the machine and thereby prevent any possibility of money being withdrawn
from it without the outward movement of the drawer being recorded and it consists
essentially of a peculiar construction and arrangement of devices designed to
accomplish these objects as hereinafter more particularly explained.

In the drawings like letters of reference indicate corresponding parts in each
figure.
A, is the case and, B, the lid, which when shut as indicated in Fig. 2, completely.
encloses all the operating mechanism with the exception of the keys by which the
mechanism is set in motion to perform the function arranged for each part as
hereinafter more particularly explained.
Near the ends of the case and rigidly secured in place in any suitable manner are
a pair of standard plates, C, which support all the interior mechanism.
The main shaft, D, of the registering mechanism is journalled in bearings in the
standard plates, C, and extends entirely across the case near the front side thereof.
At one end of the main shaft, D, and outside of the standard plates, C, I secure a

page_text: .
turning knob E, (see Figs. 1 and, 4) whereby the main shaft is adapted to be
revolved in its bearings for the purpose of turning all the numbered discs to the
zero or naught point, as will be described hereinafter.
Arranged on the main shaft is a series of discs 1, 2, 3, 4, 5, 6, 7, and, 8.
The disc, 1, is arranged with the numeral, 0, and the fraction situated on the
periphery of the disc opposite each other and this disc is intended for the
registration of the half-pennies. The disc, 2, is arranged with the numerals from, 0,
to 11, to indicate the pence. The disc, 3, is arranged with the numerals from, 0,
to 9, and the disc, 4, with the numerals, 0, and 10, arranged alternately on the
periphery of the disc. The discs, 3, and, 4, are intended for the registration of the
shillings the disc, 3, being arranged to register the shillings up to, 9, and
the combined discs, 3, and, 4, registering the shillings up to 19. After this
number has been registered of course the disc is carried by the mechanism
hereinafter described to the pounds, which are arranged to carry from one to
the other.
In the drawings as shown in Figs. 2 and, 3, the amount opposite the slot of the
cover would be £987 19s. 11, pence. The discs 1, 2, 3, 4 and, 5, are provided
with spur wheels, 1, 2, 3, 4, and, 5", respectively which are secured rigidly to or
formed integrally with their respective discs. The said discs are arranged loosely
on the main shaft and are independently revoluble thereon and the said spur
wheels are all the same diameter and provided with the same number of teeth.
The number of discs may be increased at will to adapt the machine for registering
sums of any desired magnitude. The disc, 5, is connected to the disc, 6, by a
carrying device, the disc, 6, is connected to the disc, 7, by a similar carrying device
as also the disc, 7, to the disc, 8. Should it be desired to register sums of a
greater magnitude than what these discs provide for, each or any further discs
required would be connected by the same carrying device as above mentioned and
as hereinafter described.
The hub or central sleeve, F, of each disc carries a stop pin, f, and a spiral
spring, g, to normally force the same inwardly (see Fig. 6). G, is a longitudinal
groove made in the shaft, D, and extending from outside to outside of the hubs of
the discs, 1, and, 8. One side of the groove, G, is inclined and the other is radial.
The stop pins, f, are preferably arranged in the sleeves or central sleeves of each of
the discs in line, radially with the naughts or zero-marks on said dises and hence it
follows that, when the straight sides of the inner ends of the stop pins, f, are in
engagement with the radial side of the groove, G, and of the discs, it will present
their naughts or zero marks in the front portion of the discs, where an opening,
is made in the cover as described in the Patent referred to. g', is a recess made in
the shaft, D, one side being bevelled off to shaft, and the other side radial.
The recess, g, is designed to form a stop for the pin, f, and prevent final disc from
being rotated farther than the ninth digit. The hinged cover, B, with which the
case is provided and which is usually locked is arranged over the plate or cover, H,
and when the cover, B, is opened the numbers on the discs opposite the openings
can easily be read. The discs, 1, 2, 3, 4, 5, 6, 7, and, 8, are held in position, so as
to prevent them moving laterally on the shaft by the collars, i, abutting the outer
ends of the sleeves, F. C¹, C", C, and, C, are intermediate standard plates, which
form auxiliary supports for the operating mechanism.
It will be noticed on
reference to Figs. 1 and, 3, that the sleeve, F, of the disc, 1, is elongated in form, so as
to bring the gear wheel, 1*, into mesh with the operating gearing of the first bank
of keys.
The gear wheels, 2ª, 3, 4*, and, 5ª, are secured to the sleeves, F, which form
part of their respective registering discs, 2, 3, 4, and, 5, to which discs the gear
wheels in each of these cases are closely situated. The registering disc, 1, derives
motion from the keys of the first bank through the gear wheel, 1, intermediate
gear 1b, situated on the counter shaft, J, which extends throughout the breadth of
the machine and is supported in the standard plates, C, and gear wheel, 1, which
revolves on the shaft, K, supporting the operating registering sleeves, K¹, K", K³,

page_text: K', K, of each of the five banks shown in Fig. 1. The registering disc, 2, derives
motion from the keys of the second bank through the gear wheel, 2, intermediate
gear wheel, 2b, which is situated at one end of the sleeve, J¹, which is loose on the
shaft, J, the gear wheel, 21, situated at the opposite end of the sleeve J¹, and gear
wheel, 2, on the shaft, K. The registering disc, 3, derives motion from the keys
of the third bank through the gear wheel, 3, intermediate gear wheel, 3b, situated
on the counter shaft, J, and gear wheel, 3°, on the shaft, K. The registering
disc, 4, derives motion from the keys of the fourth bank through the gear wheel, 4*,
intermediate gear, 4b, situated on the counter shaft, J, and gear, 4°, situated on the
shaft, K. The registering disc, 5, derives motion from the keys of the fifth bank
through the gear wheel, 5*, intermediate gear, 5b, and, 51, secured to the sleeve J",
situated on the shaft, J, and gear wheel, 5, on the shaft, K. In each case each
gear wheel, 1, 2, 3, 4, and, 5°, is secured to or forms part of its respective ratchet
sleeve, K, K, K³, 'K', K'.
For the sake of convenience in operating I show twenty teeth in the ratchet
sleeves, K, K, K', and, K. The ratchet sleeve, K", or sleeve through which the
I also
pence registering disc is operated I make, however, with twenty-four teeth.
make all the gear wheels, 1º, 2º, 3º, 4°, and, 5, twice the diameter of the gear
wheels, 1, 2, 3, 4ª and, 5ª. It will thus be seen that the wheels, 1, 2, 3, 4*,
and, 5, will make one complete revolution upon each half revolution of the gear
wheels, 1, 2, 3, 4*, and, 5. As each of these sets of gears above mentioned are
entirely independent of each other it will be seen that each bank of keys will be
operated to register any number on its respective disc simultaneously. The
registering sleeves, K', K", K³, K, and, K³, are operated by a corresponding
number of sets of vertically moving ratchet bars, 10, 1, 1, 18, and, 1, each set of
which is provided with a series of ratchet teeth from 1 to 9, with the exception of
the ratchet bar id, which is provided with five teeth, to semi-rotate the half pence
disc at each downward depresssion of its key and the ratchet bar, 1, which is
provided with a series of teeth from, 1, to, 11, and the bar, 18, which is provided
with one tooth. Each ratchet bar is pivoted at its lower end to the rear end, L,
of its respective finger key by means of a pin 1. Each of the ratchet bars of each
bank is operated by a finger key in identically the same manner.
2, 2, 28, and, 2, are serrated discs secured on the opposite ends of the ratchet
sleeves, K, K³, K', and, K, to that on which the gear wheels, 2, 3, 4º, and, 5*,
are situated.
Each ratchet bar is shaped at its rear end in the form of a
rectangular frame, the bottom end of which rests on the supporting angle bar, M.
The inside edge of the vertical bar of the rectangular frame of the ratchet bar is
provided with a number of teeth, m, equal in length to the space travelled by the
ratchet bar in its upward movement. These teeth in each bar co-act with a spring
dog, m', pivoted within the rectangular frame upon the dividing plates, M', which
are fastened by screws to the cross bar, M, and form a means for arresting any
ratchet bar until the full upward stroke has been reached, thus ensuring the perfect
co-acting of the ratchet bars and sleeve, so as to produce a positive and correct
record of the operation and proper registration when used with the mechanism
hereinafter described. The top end of each ratchet bar is provided with vertical
projections, m¹, to retain the ratchet bar in its normal position and the bottom end
of the rectangular frame of the ratchet bar has a forwardly extending curved
projecting tooth M³. The operation of the ratchet bar will be described herein-
after as also the means whereby the carrying is done from one bank to the next.
In order to provide a simple and effective means of bringing the keys up into
position after they have been depressed to register a number I provide a bar O,
which is secured at each end to the inner side of the brackets, o, extending from
and secured to the shaft P, upon which the fiuger keys are pivoted. The
brackets, o, are secured one at each end of the shaft, P, close to the inner side of
the standard plates, C. The forward ends, o, of the bracket, o, extend obliquely
and upwardly and are connected to the end standard plates, C, by the spiral
springs, o". It will now be seen that upon every downward pressure of the key in

page_text: any of the banks or more than one key at a time that the bar having a tension
exerted upon it by the springs, o", connected to the ends of the brackets 0, will
upon every depression of the key and its being released force each and every key
depressed into the normal position shown in Fig. 2. The rear ends, of the
brackets, o, extend rearwardly as indicated by dotted lines in Fig. 2 and full lines
in Fig. 4, and are connected by the rods, Q, to the arms, r, secured on the ends of
the rocking shaft, R, which is supported in bearings in the standard plates, C, see
full lines in Figs. 1 and, 3, and dotted lines in Fig. 2. The utility of the rocking
shaft, R, I shall describe hereinafter.
I shall now describe the mechanism for controlling the opening of the cash
drawer, which is controlled by the operation of any one of the keys. 15, is the drawer
which has a slight incline forwardly and is supported on rollers, 16. 17, is a
pressure bar, which is designed to release the drawer after the key first having
been operated. The pressure bar, 17, has its ends connected to or supported upon
the levers, 18. The lever at one end of the case is a short one as indicated by the
cross dotted lines in Fig. 2, but at the other is long as indicated by dotted lines
considerably to the rear of the dotted lines showing the short lever. The levers, 18,
are pivoted at, 19. 20, is a bar also pivoted at, 19, securely held in alignment
with the long lever, 18, by the stop pin, 21, which extends beneath the bar,. 20.
22, is a toothed wheel, which is designed to be engaged by the spring dogs, 23
and, 24. 25, is a curved plate secured to the rear end of the bracket, o, and, 26, is
a curved push bar pivoted on the end of the plate, 25. The normal position of
the teeth of the toothed wheel, 22, and the push bar, 26, and spring dogs, 23
and, 24, is indicated in dotted lines in Fig. 2, in which it will be seen that the lower
end of the push bar, 26, rests between two teeth and the spring dogs, 23, and, 24,
are outside the periphery of the wheel, 22. 27, is an angle plate stop secured to
the side of the drawer and normally abutting the end of the bar, 20. 28, is a flat
spring secured on the pivot, 19, and pressing against the stop pin, 29, so as to
securely hold the pressure bar, 17, in the position shown in the drawing. 30, is a
stop block secured on the end of the bar, 20. It will be seen that when the toothed
wheel is in the normal position shown in dotted lines that the stop block will be
opposite and in proximity to one of the teeth, consequently it will be impossible
for the bar, 20, to raise and release the stop, 27. When it is desired to open the
drawer it is necessary first that a key should be operated and as upon evey operation
of a key, such operation is registered by mechanism bereinafter described it will
.be impossible for the drawer to be opened without the proprietor being aware of
the fact.
In order to provide for the opening of the drawer by first depressing one of the
fingers I have provided the mechanism described above which is actuated as follows.
Upon the key being depressed the bar, O, forces the forward end of the bracket, o,
downwardly thereby drawing the push bar, 26, forwardly so as to throw the toothed
wheel, 22, into the position shown by full lines in Fig. 2, the space between two
teeth now being opposite the stop block, 30. By pressing upon the bar, 17, the
bar, 20, will be raised by the stop pin, 21, of the lever, 18, so as to tilt its inner
end above the stop, 27. The drawer now being on an incline and supported upon
rollers, 16, will move out, the stop 27, passing beneath the bar, 20. Upon the
drawer passing outwardly and the block, 30, passing upwardly the spring dogs, 23,
being in the position shown in Fig. 20, the dog, 24, will be forced on the top of one
of the teeth of the toothed wheel, 22. The spring, 28, pressing upon the stop
pin, 29, tilts the lever, 18, so as to raise the forward end and depress the rear end,
thereby bringing the dog, 24, downwardly so as to cause the toothed wheel to pass
around in the direction indicated by arrow and assume the position shown in dotted
lines in Fig. 2, with a tooth opposite the stop block, 30, whereupon the push bar, 26,
is caused to fall immediately into the position shown in dotted lines in Fig. 2, and
the lever, 18, and bar, 20, in the position shown in full lines. The dog, 23, will
also assume the position shown in dotted lines. When the drawer is pushed in again
as the bar, 20, is swung upon the pivot, 19, the stop, 27, as it passes inwardly will

page_text: simply raise the bar, 20, on its pivot until it passes it, when the bar, 20, will
immediately drop down and abutt the stop 27, thereby locking the drawer.
In order that no more than one key of each bank may be operated at the same
time I provide the following mechanism. W, is the rear frame of the machine,
which is secured between the standard plates, C. w, are a series of slots, which are
cut in the frame, W. The slots w, correspond in number to the number of keys in
each bank and straddle the rear end, L₁, of each key. X, is an adjustable plate
having also a series of slots, a, of the same width as the slots, r, in the plate, W.
The plate, X, is supported on pins, ', secured in the plate, W, and extending
through slots, ", made in the plate, X. The lower ends of the blanks, ³, are
bevelled at the left hand side so that the lower corner of each bevel is situated
directly behind the corresponding side of the slot, w. W, is a spring secured at
the lower end to the plate, W, and pressing on its upper end against the pin,,
secured in the plate, X. As there is only one key for the halfpenny it will of
course be understood that no plate, X, will be required.
In the pence, shilling, ten shilling and pound banks the plates, W, and, X, slotted
and constructed as above described will be required, the pence bank: plates W, and,
X, being arranged with twelve slots and the other banks with ten slots each. The
plate, X, is slightly separated from the plate, W, so as to permit of the insertion
of the spring or springs, W', and is so set in relation to the plate, W, that all the
slots, r, are normally arranged as to the slots, w, as shown in Figs. 4 and, 7. Each
blank,, is bevelled at, a, the width of the bevel being gradually increased from
left to right, so that the first slot on the left is entirely clear, and the following
slots to the right are gradually overhung by the increased width of the bevel as
described above. When the rear end, L', of any one of the keys is raised it will
be seen on reference to Figs. 4 and, 7, that the key 5 in its upward ascent into one
of the slots, wo, will engage with the bevel, a', and force the frame, X, to the left
against the resistance of the spring, W', so that the remaining slots, w, will be
closed by the blanks, 23. It will now be understood that it will be impossible from
the construction indicated for more than one key to be operated in any one of the
banks.
I shall next proceed to describe the manner in which the tablets, which expose
the amount of the sale to the view of the purchaser, are operated. It will be seen
on reference to Figs. 2 and, 4, that the tablets Y, for each bank, are fastened on a
corresponding number of rods, y, which in their normal position rest upon a
corresponding number of ratchet bars for each bank attached to the rear end of the
finger keys, L, as hereinbefore described. Arranged on the shaft, P, are five banks
of finger keys, 1, 2, 3, 4, and, 5e, there being one key in the first bank, eleven in
the second bank, nine in the third bank, one in the fourth bank and nine in the fifth
bank. The key of the first bank is designated one-half penny and the tablet the
same. The keys in the second bank are numbered from one to eleven pence,
the tablets corresponding, the keys in the third bank from one to nine shillings, the
tablets corresponding, the key of the fourth bank being designated ten shillings, the
tablet corresponding and the keys of the fifth bank being numbered from £1 to £9
with the tablets the same. The rods, y, are held in a vertical position by the guide
bars, 2, 2. Z, is a swinging frame pivoted at each end, Z1, on the standard
plates, C. The cross bar, 3, of the swinging frame, Z, in its normal position is
beneath the guide bar, z, and has extending from below it a hanger 1, upon which
is pivoted the rocking dog, . The front end of the dog, 28, is held against the
shoulder 2, formed on the hanger, 2, above the dog, by the spiral spring, 27, which
is secured at its upper end to the rear end of the dog and at its lower end suitably
connected to the standard plates, C., is a spiral spring connected at one end to
the swinging frame, Z, and at the other end to the standard plates, C. j, is a
detent secured on one end to the rocking shaft, R, in proximity to the arm, r.
detent, j', being secured on the rocking shaft, R, is raised at each depression of one
or more of the series of finger keys so as to engage with the lower side of the front
end of the rocking dog, . As the front end of the rocking dog, ³, is held by the
The

page_text: spiral spring, ', against the shoulder, 26, the detent, j', will tilt or throw back the
swinging frame, Z, on its pivot, Z. ", is a pin which projects from the rear end
of each of the rods, y, and in its normal position rests upon the bottom guide bar, 21.
Upon the depression of a key in each or any of the banks, the ratchet bar attached
to the rear end, L', of the finger keys, throws the pin, ", upwardly and as the
detent,, causes the swinging frame, Z, to move rearwardly simultaneously the
pin, j, is allowed a free vertical passageway past the cross bar, 2, of the swinging
frame, Z. At this juncture the detent, j', has been raised so high that it passes the
front end of the rocking dog, 5, and the spiral spring, 8, causes the swinging
frame Z, to move forwardly into its normal position, thus throwing the cross bar, a³,
beneath the pin ", thereby retarding the descent of the rod, y, in other words
holding the said rod up, so as to expose the tablet corresponding to the number on
the key operated, to the view of the purchaser. It will now be seen that the tablet
or tablets now raised in each bank will remain exposed until a key has been again
operated and the swinging frame, Z, will be again caused to move upwardly and
allow the pin or pins, ", supported on the cross bar, 23, to drop into their normal
position and the pin,, on the rod which is raised to rest on the cross bar, Z. This
raising and releasing of the pin, j, on the rod, y, will of course recur upon each
depression of one or more of the finger keys.
Next in order I shall proceed to describe the manner in which the ratchet bar is
operated from the key and the ratchet sleeves on the shaft, K, are operated from
such ratchet bar also the manner in which the carrying is done from the halfpenny
to the pence, the pence to the shillings, shillings to ten-shillings and ten-shillings to
pounds. Referring to Fig. 2, 1', is the ratchet bar, which is pivoted at the bottom
at,, to the rear end, L, of the key. On reference to Figs. 2 and, 2B, the
construction and operation of the ratchet bar with the sleeve will be understood.
Each ratchet bar has a ratchet toothed rack, 1', which engages with one of the
sleeves on the shaft, K. All the sleeves on the shaft, K, are provided with twenty
teeth with the exception of the sleeve in the pence bank, which is provided with
twenty-four teeth (see Fig. 24). All of the ratchet toothed racks in each ratchet
bar are constructed with teeth from one to 9, with the exception of the ratchet bars
of the half-pence and pence banks, as before described. Within the rectangular
frame is arranged as before described a spring dog, m', which is designed to engage
with a series of teeth, mn, made in the rear bar of the frame (see full lines in Fig. 2,
and dotted lines in Fig. 2B). Extending laterally from the rear of each ratchet bar
is a curved projection, m³. m², is a dog pivoted at me, and having a pin, m³, secured
in its upper end, which works in the slot, m', made in the dividing plate, M¹.
a spring secured to the plate, M', and having its upper end resting against the top
of the dog, mt, so as to hold the pin against the inner end of the slot, m'. The
forwardly projecting tooth, M³, before described is provided with a tooth, M,
situated on the same level as the top of the bottom tooth of the rack, l.
tooth, M, and bottom tooth of the rack, controls the upward movement of the
ratchet bar by locking the teeth of the sleeve on the shaft, K, and also serve to
prevent the momentum caused by the upward movement of the rack bringing
around the ratchet sleeve any farther than rotated by the number of teeth of the
rack, l.
m³, is
The
The operation of the ratchet bar from the key is as follows. Upon the down-
ward pressure of a key the ratchet bar is caused to move upwardly until the teeth
of the ratchet sleeve on the shaft, K, comes in contact with the tooth, M, and
bottom tooth of the rack l. In its upper ascent it will be seen that the spring
dog, m', sliding past the teeth, m, of the rectangular frame of the ratchet bar will
pass such teeth but should the key be released before the full movement of the
ratchet bar is accomplished the dog, m', will engage with one of the teeth, m, and
It will thus be seen that it
prevent the key from falling back as before described.
is absolutely necessary that the full upward movement of the rack must be
completed by the full depression of the key before another key in the same bank
can be operated, the plates, W, and, X, of course serving as before described to

page_text: provide for this result. In this manner inaccurate sums or numbers are prevented
from being recorded on the registering disc connected with the ratchet bars in any
bank. It is necessary in order that the ratchet bar may drop again on the
completion of its upward movement that some means should be provided whereby
the dog, m', should be prevented from engaging with the teeth, m, of the rect-
angular frame of the ratchet bar. For this purpose I provide as above stated the
swinging dog, m'. It will be seen on reference to Fig. 2B, which is a view of
portion of the ratchet bar on the opposite side to that shown in Fig. 2, that the
lateral projection, m³, in the upward movement of the ratchet bar will force the
dog, m', so that the stop pin, mo, will pass to the rear end of the slot, m', thereby
enabling the rectangular frame of the ratchet bar to pass upwardly and allow of the
ratchet toothed rack, l, engaging with the sleeve on the shaft K, to perform its
function. When the projection, m³, has passed the swinging dog, m, the spring, m³,
causes the swinging dog to spring back behind the rectangular portion of the
ratchet bar. Upon the key being released it will now be seen that the projection, m³,
being to the outside of the top point of the swinging dog, m', will pass to the
outside of the dog, m, thereby drawing the toothed rack from engagement with the
sleeve on the shaft, K, and the spring dog, m', from engagement with the teeth, m,.
formed in the rear bar of the rectangular frame of the ratchet bar. The
projection, m³, throws back the upper end of the ratchet bar, and passes down on
the rear side of the dog, m', which as it gets past the pivot point causes the dog to
swing upon its pivot and allow the projection to return to the normal position
shown in Figs. 2 and, 2". By this means the engagement of the ratchet bar in its
upward movement and its release so as to allow of its free downward movement into
its normal position is ensured.
I shall now describe the manner in which the carrying is done from one bank
to the bank of the next higher denomination referring particularly to Figs. 1, 2,
24, 2B, and, 3. a, a, a, and, a³, are plates secured on the intermediate standard
plates, C, C, C, and, C, respectively on their left hand sides.
As all the plates are secured in the same way and their mechanism co-acts
identically for carrying I shall describe the plate, a", secured on the left hand side
of the standard plate, C³, which is the standard plate to the left of the section
line -y shown in Fig. 1. The plate, a", is supported on the side of the plate, C³,
by the pins, b, secured in the plate, C³, and extending through slots, b', made
in the plate, al. c, is a rocking detent pivoted at, c², on the upward extension, c",
of the plate, a". The detent, c, is pivoted on the right side of the plate, a",
and has a pin, c³, which is designed to come in contact with the top of the
plate and control the movement of the detent, c. c, is a spring fastened to the
plate, a, at one end and curved so that its other end presses against the pin, c,
extending out laterally from the detent, c, as indicated in Fig. 3, in full lines,
and dotted lines in Fig. 2. The normal tendency of the spring is to force the
detent upwardly at its inner end. c, is a lever pivoted at, c'. The upper end of
the lever engages with a projection, 8, formed at the lower side of the detent.
, is the lower enlarged tapered end of the lever, c., is a curved spring which
is secured on the standard plate, C³, and has its free end pressing against the
back of the lever, c. c, is a push lever pivoted at ci, on the downward
projection, a, forming part of the plate, a". a, and, a', are forward and rear
stops of the push lever, c, (see dotted lines in Fig. 2 and for corresponding
construction full lines in Fig. 3) in which the lever and stops are shown in
connection with the plate, a. The lever, c, shown in Fig. 2, is designed to engage
or ride upon pins, 31, on the gear wheel, 3.
2, is the serrated disc secured on the end of the sleeve, K', next the plate, C³.
,,,and,, are arms secured to the rocking shaft, R, and extending forwardly
from it., is the arm which operates with the carrying mechanism attached to
the plate, C. Upon the downward depression of the key the ratchet bar moves
upwardly and causes the ratchet toothed rack, 1, to engage with the ratchet

page_text: sleeve, K³, and move it the corresponding distance to the number of teeth in the
ratchet bar. The ratchet sleeve, K', is attached to the gear wheel, 3, at the right
hand side of the standard plate, C. The gear wheel, 3, is shown broken away in
the drawing and has two pins, 31, one of which is shown in full and the other
dotted beneath the enlarged end of the lever, c. The pins, 3º¹, are situated
diametrically opposite each other and are designed to operate upon the lever, 8,
upon each half revolution of the gear wheel, 3, which half revolution produces a
full revolution of its corresponding disc, 3.
It will now be seen that upon the ratchet sleeve K³, being turned around nine
teeth so that one of the pins, 31, is brought beneath the surface of the lever, c,
that upon the next upward movement of a ratchet bar in the same bank having
one tooth being effected the pin, 31, will tilt the lever, c, as it is being brought
past it in the direction indicated by arrow, so as to bring the upper end of the
lever, c, beneath the projection, c, of the detent, c. The spring, e, pressing
against the pin, e, will now force the rear end of the detent, c, upwardly until the
stop pin, c, at the forward end strikes the top of the plate, a", in which position
it is held by the spring, c. During the period that the ratchet sleeve has been
operated by its key the bar, O, will be raised, raising with it the bracket, 0, and
its rear end, o³, which being connected by the bar, Q, to the arm, r, secured on the
end of the rocking shaft, R, will bring the arm, 7, about a quarter of a revolution
to the rear. As the circle described by the arm, r, when being brought rearwardly
is outside the rear end of the detent, such detent will not be effected by the quarter
revolution to the rear nor will it by the forward movement of the arm under
ordinary circumstances where the lever, c, and detent c, are in the position shown
in full lines in Fig. 2. When, however, the lever c has released the detent c so
that it is thrown up, such detent will be within the circle described by the arm, 3,
so that when the finger is released and is bringing by means of the connectio..
before described, the arm, r³, back again into the position shown in Fig. 2,
such arm, ³, will strike the end of the detent, c, which is held solid by the
pin, c, pressing against the top of the plate, al, and by this means carry the
said plate, a", forward until the pins on the plate, C³, reach the end of the slots b'.
in the plate, all. Immediately, however, before the pin, b, reaches the en.
of the slot, b', the end of the arm, ³, has passed the end of the detent.
It will now immediately assume the position shown in Fig. 2. As the plate, a",
is moved forward as above described the push lever, c¹¹, is caused to engage with
one of the teeth of the serrated disc, 25, and the movement of the plate, a", is suc!:
that the push lever c", will move just sufficiently forward so as to bring the serrated
disc around the space of one tooth of such serrated disc or one tooth of the
corresponding ratchet sleeve in the adjoining bank thereby turning its respective
disc, 4, one space. The stop, a, against which the top of the lever, el, abutts
when it has given the serrated disc, 28, its full throw, thus serves to lock the
serrated disc for the moment so as to prevent any momentum being given to the disc
or in other words it being given more than its correct throw. It will now be
understood that the disc, 4, will be moved forward one space and the disc, 3, will
be brought to the naught or zero-point as the pin, c, has passed the enlarged end
of the lever. After the plate, an, has been pushed forward by the arm, 3, and
relieved from such arm the spring, 3%, pressing against the pin, 33, on the
plate, al, will force the plate back so that the pins, b, will pass to the forward end
of the slots, b. The detent, c, in passing backwardly will come in contact with
the upper end of the lever co, which is held up by the spring, co, and the
projection, coming against the top lever will force it into its normal position as
indicated in Fig. 2, thus rendering the mechanism ready for carrying again. All
the carrying mechanism connected with the ratchet sleeves K₁, K", K³, K³,
and, K, is identically the same as that connected with the sleeve, K, and operates
in exactly the same way so that the description above is the exact manuer in which
the carrying is done from the disc 1 to 2, 2-3, 3-4, 4-5. It will of course be

page_text: understood that the arms, 1, 11, 78, r, are arranged consecutively as to part
rotation as it is necessary that the carrying from one disc to the other should be
done one after the other.
It will be seen from the above description that each of the banks of keys is
operated independently to register on its respective disc and yet the carrying is
done from one to the other without interfering with the independent working of
each bank, which operates the discs, 1, 2, 3, 4, 5. The carrying is effected from the
disc 5 to the disc, 6, and from the disc, 6, to the disc, 7, and from the disc, 7, to
the disc, 8, and to any further discs that may be located on the shaft, D, by
differently operating mechanism than that by which the registering disc for each
bank is operated and this mechanisn I shall now describe. The discs, 5, 6, and, 7,
have a series of projections, 51, 6¹ and, 7', extending from their face, the projections
in each case corresponding in number to the numerals on the discs and are located
in position directly opposite these numerals. The discs, 1, 2, 3, 4, have also
projections, 11, 21, 31, and, 4', projecting from their faces and correspondingly
arranged to those on the discs, 5, 6, and, 7, but as these are intended for the
purpose of holding the disc rigid after it has been rotated or partially rotated
shall describe them subsequently.
In Figs. 2, 3, and, 3^, I exhibit the mechanism for carrying from the disc, 5, to
the disc, 6, and from the disc, 6, to the disc, 7, and from the disc, 7, to the disc 8,
such as indicated by dotted lines in Fig. 3, and full lines in Fig. 1. N, N', N", are
three toothed wheels journalled in the studs, n, supported in the end of the
arms, n', the rear ends of which are secured on the spindle, ", which is journalled
at the end in the standard plates, C. The wheels, N, N1, N", have teeth, n³, of
peculiar construction as shown in the drawings. n', are pins extending from the
centre of each tooth laterally. The normal position of any of the teeth, ³, in
relation to any of the discs will be seen on reference to Fig. 2, in which it will be
noticed that two pins are always close to the periphery of a disc. The width of
the tooth, n³, of the wheels, N, N' N", engages or meshes with the pins, 61, and, 71,
and the pins, 8', on the disc, 8, shown in dotted in Fig. 3.
P, is a cam collar secured on the shaft, D, between the discs, 5 and, 6, 6 and, 7,
and 7 and, 8. The mechanism co-acting with this collar is the same in each case.
shall describe it referring only to discs, 7, and, 8, the disc, 8, of which is shown
dotted and is provided with pins, 8', also shown dotted. In so describing the
carrying from 7 to 8 the carrying from 5 to 6 and 6 to 7 will be understood.
P is an elongated ring provided with two lugs, p, and p', at the top and bottom
of the ring respectively. p", is an arm which extends into a notch, ³, made in
the edge of the disc, 7. The collar, P, is shown in full lines in Fig. 3, and dotted
lines in Fig. 34, and has a raised portion, P³, which extends partially around it to
the front and slightly to the bottom. The elongated ring, P, is forced by the
lateral lug, p', as it passes around the raised portion, P3, of the collar, P¹, so that
the arm p", extends through the notch, p³, sufficiently far so that in a sweep it will
come in contact with one of the pins, n', which extend laterally from the right
hand side of the teeth, n³. The arm, p, of the ring, P" as the disc is caused to
revolve brings the pin, n, rearwardly until the next succeeding pin is in the same
position as the preceding pin formerly was. When this is done the arm is suddenly.
thrown in by the lug, p, of the ring, P", rising upon the raised portion, P³, of the
collar, P. The arm, p", is thus thrown within the periphery of the disc, 7, in
which position it continues to remain until the lug, p', again rises on the raised
portion, P³, of the collar, P', when the arm, p", is thrown out through the notch, p³,
ready to engage the pin, nt, so as to cause the toothed wheel, N", to move another
tooth. As the wheel N, engages with the pins, 81, it will be seen that upon each
full revolution of the disc, 7, that is the disc, 7, moving ten units of its denomination
the disc 8, will be carried one digit of its denomination.
It is necessary in order that the discs may be kept locked that the pins, n', in
their normal position abut the periphery of the disc. In order to provide for the
arm carrying the pin, n, one-tenth of the revolution of the co-acting disc, I
B

page_text: and
provide a supplemental notch p', (Figure 3) forming part of the notch, p',
situated before it as to the direction of rotation. When the digit, O, on the
periphery of the disc, 7, is opposite the opening in the cover plate the arm is in
the position shown in Fig. 34, and a pin, n', is before the arm, as to the direction of
rotation and within the notch, p, in front of the notch, p. The arm as it rotates
brings the pin, n', within the periphery until one-tenth of the revolution of the
disc, 7, is accomplished whereupon the pin, n', passes without the periphery or
rim of the disc upon the said disc having become locked as shown in Fig. 2.
n°, is an arm secured to the end of the spindle, n", and connected by the springs, no,
to a suitable stud on the standard plate as shown. n', is an arm pivoted at, n³, and
provided with a tooth, n, which engages with the notch, no, in the escutcheon of
the knob E. The knob, E, is securely fastened to the end of the shaft, D. The
tooth, n³, is held in engagement with the notch, no, in the escutcheon of the knob, E,
by the spring, n, which is secured to the lower end of the arm, a', and to a hook
on the standard plate, C. It will thus be seen that the tooth, no, of the arın, n',
projecting into the notch, no, of the escutcheon of the knob, E, will hold the
shaft, D, from rotating. When it is desired to bring all the discs back to zero it
is necessary to press upon the outer end of the arm n, so as to relieve the tooth, 1,
from engagement with the notch, n¹º. At the same time this is done the arm, n¹,
which is secured to the spindle, n", is thrown downwardly and the teeth, n³, of the
wheels, N, N', N", are thrown out of mesh with the pins, 61, 71, and, 81, of the
discs, 6, 7, and, 8, thereby allowing the shaft, D, to be freely turned by the knob, E,
back to zero. When the discs are turned back to zero the springs, n, and n¹¹, will
serve to bring the teeth of the wheels, N, N', N", into mesh with the pins, 6', 71,
and, 81, of the discs 6, 7, 8, and the tooth, n, of the arm, n', into the notch no,
made in the escutcheon of the knob, E, thus restoring the parts again to the normal
position.
In order to provide against the possibility of the machine being tampered with
by dishonest persons by attempting to turn the discs around to zero and then
restore the amount that formerly appeared in front of the slot I provide preferably
three combination wheels, Q', Q", and, Q³, supported on the stud Q. These
combination wheels are provided with pointed teeth and have letters situated
between each of the teeth. In the combination shown the letter, B, in the
wheel, Q, A, in the wheel, Q", and, D, in the wheel, Q, are in alignment before
the opening in the cover, H. The teeth mesh with the collars, U₁, U", and, U'
which are provided with recesses, u, ul, and, u³, respectively. These recesses are
set at different portions of the periphery of the collars, U₁, U", and U³. The
combination wheels, Q, Q", and, Q, although of the same diameter are each
provided with a different number of teeth. They are so arranged, however, that
the combination before the slot is always in alignment. The other letters on the
discs are not in alignment. At each revolution of the shaft, D, it will of course be
seen that as there are a different number of teeth in each combination wheel that they
will travel different distances. As the teeth of the wheel, Q, Q", and, Q', are
within the circle of the collars, U, U₁, U", it will be seen that the shaft, D,
cannot turn without turning the wheels. When a certain combination is before the
opening and the shaft in its normal position any change in the position of the shaft
will be indicated before the opening. Consequently if a dishonest person should
attempt to turn the shaft, D, by the knob, E, he would change the combina-
tion B, A, D, which is the combination supposed to be appearing before the opening
and it would be impossible on account of the infinite number of combinations
produced by these wheels in their engagement with the collars for the same com-
bination to be restored. If the combination was therefore altered the proprietor
would be fully aware that the machine had been tampered with.
In order that the amount on the registering discs may be readily read and also
to prevent anything from being dropped into the machine, so as to prevent its
working properly I provide as before described a cover plate, H, provided with a
slot, h, which extends from end to end of the registering discs, 1, 2, 3, 4, 5, 6, 7, 8,

page_text: and is just of sufficient width to exhibit one set of figures in alignment on the discs
for instance in the drawing the sum £987, 198, and 11 pence
in the position
directly underneath the slot. I also provide a slot in the cover plate over
the combination wheels, Q1, Q", and, Q³, the position of the wheels in this case
being directly over the letters B, A, D.
To ensure the discs coming around properly so that the numerals through the
length of the discs will be in proper alignment I provide a series of stop
arms, 9, 10, 111, 131, 14', 151, 16, 17, which are secured on the spindle, 18. The
bottom outer ends of these arms are preferably arc-shaped as shown and when held
down exactly fill up the space between the pins, 11, 21, 31, 41, 51, 61, 7', and, 8', in
each of the wheels, 1, 2, 3, 4, 5, 6, 7, and, 8. The ends of the stop arms are held
down by the spring fingers, 9, 10, 111, 13, 14", 15", 16", 17", forming part of
the plate 18. All of the stop arms are secured to a sleeve 19', which is loosely
journalled on the spindle, 18'. The spring plate, 1811, is secured to the sleeve, 191, 20º,
is a rearwardly extending arm forming part of the plate, 18". The arm, 20',
extends over an arm,, secured to the rock shaft, R. Upon every depression of
a key it will be seen from what has been before described that not only the arm, r,
but the arm,, which is attached to the rock shaft, R, will move rearwardly and
relieve the rearwardly extending arm, 20', forming part of the plate, 18", attached
to the sleeve, 191. Consequently no pressure will be exerted on any of the stop
arms by their respective springs so that each of the discs, 1, 2, 3, 4, 5, 6, 7, and, 8,
will be free to move upon the depression of the key. As any of the discs pass
around the pin on the disc will move the curved end of the stop arm outside the
circle of the disc and as the stop arms are all secured to the same sleeve every
stop arm will be moved outside the circle of its respective disc.
Immediately upon the key being released the arm, r, on the rock shaft, R, will
come back against the end of the rearward projection, 20', of the plate, 18",
thereby applying a pressure upon all the spring fingers of the plate upon their
respective arms so as to throw them back instantaneously between the pins on the
discs. By this means the alignment of the numerals throughout the length of the
discs is provided for.
It will be seen that as the shaft, D, has to be turned by the knob, E, in
the direction indicated by arrow so as to bring all the discs back to zero that the
spring fingers of the plate, 18", which press upon the stop arms will give sufficiently
to allow of the discs being rotated so as to restore each disc to zero below the slot, h,
in the plate, H, and into perfect alignment.
The
In order to provide against the upsetting of the rocking dog when the discs are
being turned back to zero by the knob, E, I provide a rock shaft, E', which extends
throughout the length and is supported in the standard plates. The rock shaft, E',
is provided with arms, e', which extend over the pins, c, in the detent, c.
normal position of the arms, e', is that shown in Figs. 2 and 3. The outer end of
the rock shaft, E', at one side of the machine is provided with an arm, E. Et, is
a bar connecting the end of the arm, E, to a pin, el, on the arm, n'. When it is
desired to turn the discs back to zero it is necessary as before stated to press down
the outer end of the arm, n', so as to withdraw the tooth, n³, from engagement
with the notch, no, in the escutcheon of the knob, E. In so doing the arms e¹, are
thrown into the dotted position shown in Figs. 2 and, 3, so as to rest upon the top
of the pins, c. When as shown in Fig. 2, the disc, 3, is brought around to zero
the pin, 31, will have no effect except merely tilting the lever, c', as it passes its
lower end, c. If the arm, e', and rock shaft, E¹, were not provided it will be seen
that when the shaft, E, has been turned around so as to bring the discs back to
zero the detent, c, would be released as hereinbefore described by the pins, 3º¹,
passing beneath the end, c, of the lever, c, and throw it up into the position
within the sweep or circle of the arm, . Consequently upon the first operation of
the keys in this bank or any bank to register any sum, that the amount will be
registered on the respective discs, and upon the return of said finger keys to their
normal position one uumeral of the next denomination in each bank would be

page_text: carried by the arm, r, engaging with the end of the detent, c, as it moves back into
its normal position thus producing an incorrect amount. By providing the arms e¹,
operated as herein before described such a result is absolutely avoided.
In a machine such as hereinbefore described I obtain a two-fold advantage by
the independent and successive means of carrying which I shall now illustrate. The
amount exhibited before the opening of the cover plate is £987, 19s. and 11, pence,
which by the depression of a halfpenny key will be changed to £988, naughts
appearing before the openings on the shilling discs, pence disc and halfpenny disc,
the carrying being effected in the following manner. Upon the next depression
of the halfpenny key the numeral 0, will be brought around in the position beneath
the opening, h, by the ratchet bar and sleeve in the halfpenny bank in the same
manner as described in reference to the bank shown in Fig. 2. At the same time
one of the pins on the spur wheel, 1°, comes beneath the end, c, of the lever, c,
tilting the said lever and allowing of the detent, c, being forced up within the
circle of the arm; r. The arm, r¹, being now in the same position shown in
dotted lines as to the arm, r, in Fig. 2, will upon its return carry forward the
plate, A, with its lever, c", which will move forward the serrated disc, 2, the space
of one tooth also the corresponding ratchet sleeve, K", the space of one tooth. As
the ratchet sleeve, K", has secured to it the gear wheel, 2° and the gear wheel, 2º,
moves around a corresponding distance to the serrated disc, 2, it so brings the pence
registering disc, 2, from the space with the numeral, 11, to the space with the
numeral, 0, which would now appear before the opening. The gear wheel, 2°, as
at the commencement of the movement has one of its pins underneath the lower
end, c, of its corresponding lever, it will be seen that upon the wheels moving
forward the corresponding space of one of the teeth of the serrated disc, 2, that
the pin will tilt the lever c', so as to relieve the detent, c, and throw it up within
the circle of the next arm, r", which has been moved rearwardly. Upon the
forward movement of the arm, ", the detent will be carried forward by the arm
as herein before described carrying with it the plate, A', and push lever, c", which
will move the serrated disc, 21, forward one tooth. As the serrated disc, 2', forms
a part of the ratchet sleeve, K³, and, gear wheel, 3º, it follows that the gear
wheel, 3, in moving around will move the disc, 3, forward one space and bring the
numeral, 0, on the registering disc, 3, before the opening, h. When the disc, 3º,
moves forward the space of one tooth one of the pins, 31, which is underneath the
lower end, c', of the lever, c, will in the manner hereinbefore described throw the
corresponding detent, c, upwardly and the arm, r, will cause the plate, A", to move
forward bringing with it the push lever, c, so as to throw the serrated disc, 2ª,
forward the space of one tooth and the sleeve, K', and toothed wheel, 4, attached
to it forward a corresponding space, which movement of the wheel, 4, will throw
the disc-moving mechanism herein before described and move the number, 10,
appearing before the opening, h, from it and bring the numeral, 0, before the
opening in its place. As the pin in the toothed wheel, 4, is also beneath the
end, c, of the lever, c, it follows that the detent, c, is operated and carried by
the arm, r, so as to bring the push lever, c", pivoted to the plate a³, forward,
thereby turning around the serrated disc 24, the space of one tooth. As the disc, 2ª,
forms part of the ratchet sleeve, K, to the opposite end of which is connected the
gear wheel, 5, it follows that upon the serrated disc being moved forward the space
of one tooth that the gear wheel, 5, will through the chain of gearing herein before
described move forward the registering disc, 5, one space, that is transfer the
numeral 7 forward from beneath the opening and place before the opening in its
stead the numeral, 8. The numerals, 9, 8, 8, 0, 0, 0, 0, will now appear respectively
on the registering discs, 7, 6, 5, 4, 3, 2, 1, that is to say the amount registered will
be £988 showing that by a single depression of the halfpenny key the carrying is
successively and effectually done throughout the discs, 1, 2, 3, 4, 5, 6. It will be
noticed in connection with the carrying that it is always done by the forward
movement of any or all of the arms,,,,, that is to say in each case by the
return stroke of the keys as the case may be and this will also be seen to be the

page_text: case when the carrying is done upon all or any of the keys when an amount has
been added to the total on the discs appearing before the opening in the cover as
hereinbefore described.
I shall now describe the manner in which the carrying is done on the several
discs successively and independently by the depression of two or three of the finger
keys of the several banks. I will, however, show the five banks operated but it
will be clear that any number of banks may be operated and produce correct totals
in the same manner. We will suppose as before stated that the amount appearing
before the opening is £987, 19s. and 11, pence and we will suppose that we
wish to add £2, 6s. and 4, pence to this amount by the simultaneous operation of
these keys. By depressing the half penny key, four penny key, six shilling key
and two pound key simultaneously, the numeral, 0, is caused to appear on the half-
penny disc, 1, the numeral, 3, on the pence disc, 2, the numeral, 5, on the shilling
disc, 3, the numeral, 10, on the shilling disc 4, and the numeral, 9, upon the pound
disc, 5. As the carrying is done upon the return stroke of each key, so as to move
the respective discs forward one space, it will be seen that each disc with the .
exception of the half-penny disc, 1, will be then moved forward one space so
that 4 will appear on pence disc 2, 6 on shilling disc, 3, 0, on shilling disc, 4,
and, 0, on the pound disc, 5. As the disc, 5, is moving to. O, it will be seen on
reference to Figs. 3 and, 3^, that the arm, p", will as before described through the
medium of the pins, n', and the teeth, n³, of the wheel, N, carry the disc, 6, to 9.
The amount before the opening in the cover plate will now be £990 6s. 4d.
will thus be clearly seen that although each key acts independently of the other
yet the carrying is done through the medium of the mechanism herein before
described operated at the return stroke of the key so that the discs are turned by
the depression and their rotation continued one space by the return stroke of the
finger keys and the amount indicated by the keys will be added to the total amount
on the registering disc, in this instance the amount being as before stated £990, 68.,
and, 4d.
