Improvements in Cash Registers.
A communication from Joux SHARPE, in the City of Toronto, in the County of York,
Province of Ontario, Canada, Inventor.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.,
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 an improvement in cash registers and it consists in the
peculiar construction of devices hereinafter described.
The object of this invention is to provide a cash register which is adapted to
register the amount of each sale, and keep a correct account of the sum total of all
the sales for any desired length of time, and which is provided with safeguards to
prevent it from registering inaccurate sums, and to prevent it from being tampered
with by dishonest persons to cause the machine to falsify the accounts.
A further object of the invention is to provide a cash register which is adapted to
be caused to register several amounts at the same instant.
A further object of this invention is to provide a cash register which is positive and
automatic in operation, is necessarily accurate, is strong and durable, and is not
likely to get out of order.
These objects are attained by the mechanism hereinafter described and illustrated
in the accompanying drawings in which

The bottom of the cabinet or case A is slightly inclined towards the front and on
the upper side of the bottom are mounted anti-friction rollers 13 which support the
cash drawer C; an opening D is made in the front of the ease in front of the
drawer through which the latter is adapted to slide when opened, and the said
opening is covered with a shield plate E which is hinged at its lower edge as at F.
At the ends of the shield and at right angles thereto are quadrant plates G which
extend into the case on opposite sides of the drawer and are provided at their
lower inner corners with projecting shoulders H.
Pins I project from the outer sides of the quadrant plates and are located about
centrally on the quadrant plates and near their curved edges as shown. Two flat
springs are secured to the cross bar L under the bottom of the case and the
free ends of the said springs K bear up under the shoulders H and serve to throw
the shield plate E open, and disclose the front end of the drawer when the shield
plate is released by the mechanism now to be described.
Two hooks or detents M are mounted in the ends of the case on pivots N and
are arranged on opposite sides of the drawer. The shoulders O at the outer ends of
the said hooks engage the pins I and thereby normally retain the shield plate in a
closed position, against the pressure of the springs K and the inner ends of the said
hooks are provided with slots P.
Two vertically movable rods R are guided in openings in guide brackets S which
are attached to the ends of the frame above the drawer and one above another as
shown.
The upper ends of the rods R are bent outwards at right angles to form tappets T
and the lower ends of the said rods are connected to the inner ends of the hooks M
by pins which work in the slots P.
On the rods 1 are arranged coiled extensile springs V which bear between the
upper brackets and the pins W on the rods and serve to normally force the latter
down, and thereby retain the shoulders of the hooks M. in contact with the pins I.
A pair of weight arms X are arranged at the ends of the frame F and pivoted
at their outer ends on pins Y.
The lower inner corners of the said weight arms are connected together by a
rod Z which extends lengthwise across the case and hence causes the weight arms
to operate in unison.
On the outer sides of the weight arms are arranged right angle tappet arms A
each of which has a slot in its vertical arm. Set screws extend through
these slots and threaded holes in the weight arms and serve to secure the tappet
arms thereto and adapt the latter to be adjusted.
The horizontal portions of the arms A extend into the paths of the tappets T
on the upper ends of the rods R and are adapted to engage the same when the
weight arms are raised by any of the keys and thereby cause the said rods R to
disengage the hooks M from the pins whereupon the springs K would open the
shield plate E.
The opening D being thus uncovered the drawer slides open by gravity as will
be readily understood.
As shown in Figs. 22 and 23 on the sides of the drawer at a suitable distance
from the front are secured vertical plates D' and from the inner sides of the
quadrant plates G near the lower corner thereof project pins which when the
shield plate is thrown by the springs, engage the rear sides of the plates D' and
thereby impart the initial impulse to the drawer and start the same on its outward
journey:
When closing the drawer which may be done by pushing on the handle F' on the
front thereof the plate D' engages the pins E' and as the drawer is moved inward the
said pins travel down on the rear edges of the plates and serve to turn the shield
plate on its hinges against the pressure of the spring K and close the shield plate
°

page_text: over the opening D when the hooks M engage again the pins I and lock the shield
plate in its closed position and thus render it impossible to open the drawer without
previously operating one of the keys.
Arranged in the case near the ends thereof and rigidly secured in place in any
suitable manner are a pair of standard plates F¹ which support all of the interior
mechanism.
The main shaft G of the registering mechanism is journalled in bearings in the
said standard plates and extends across the apparatus near the front. At one end of
the main shaft is formed an angular extension H' adapted to be engaged by a suitable
wrench or key 1' such as illustrated in Figure 27 and thereby the main shaft is
adapted to be revolved in its bearings for the purpose of turning all the numbered
discs to the zero or nought point as will be presently described.
Arranged on the main shaft loosely and independently revoluble thereon are a
series of discs Nos. 1, 2, 3, 4, 5, 6, 7, 8, 9, each of which is provided on its periphery
with a series of numerals, disc No. I having only two figures 0 and, disc No. 2
from 0 to 11; disc No. 3 from 0 to 19; and the remaining six discs from 0 to 9
and arranged at suitable distances apart; the numerals on disc No. 1 indicate
half pence, those on dise No. 2 indicate pence and those on disc No. 3 indicate
shillings and those on dise No. 4 indicate pounds, and those on disc No. 5 indicate
lens of pounds and those on disc No. 6 indicate hundreds of pounds and those on
dise No. 7 indicate thousands of pounds, and those on dise No. 8 indicate tens of
thousands of pounds, and those on dise No. 9 indicate hundreds of thousands of
pounds. Of course the number of dises may be increased at will to adapt the
machine for registering sums of any desired magnitude.
The said dises are provided with spur wheels 1, 2, 3, 4, 5ª, 0ª, 7, 8ª, 9ª,
respectively, the said spur wheels being rigidly secured to or formed integrally with
their respective discs as may be preferred and the said wheels being all of the same
diameter and provided with the same number of teeth.
The hub or central sleeve K' of each disc carries a stop pin L' as shown on
Figure 26 and a spring to normally force the same inward. The inner ends
of those pins are bevelled on one side as shown in Figure 26 and said inner ends
of the pins travel in grooves in the main shaft. Each groove N has an offset
or shoulder one side of which is inclined, and the other side of which is radial,
the stop pins are arranged in the hubs or central sleeves of the dises in line radially
with the noughts or zero marks on said discs, and hence it follows that when the
straight sides of the inner ends of the stop pins are in engagement with the radial
sides of the shoulders or offsets O' all of the discs will present their noughts or
zero marks to the openings P of a covered plate Figure 21 which plate is
secured on the inclined front edges of the standard plates Fa hinged cover S
with which the case is provided and which is usually locked is arranged over the
plate Rand when the said cover S is opened, the openings are disclosed and
the numbers on the discs presented to the openings can be read.
A sleeved extends from the outside of the wheel 1ª and is secured firmly
thereto; the said sleeve is loose on the shaft G and at its outer end of said
sleeve is firmly secured a spur wheel 1, which is exactly similar to its fellow
wheel 1.
A shaft T is arranged parallel with the shaft (and at a suitable distance
therefrom and has the end rigidly secured to the standard plates. On the shaft T
are loosely mounted a series of spur wheels 1, 2, 3, 4 and 5º, UT, VI, W², X, Y
and which are all of the same diameter and have the same number of teeth;
the wheel engages with the wheel Q': the wheel 2 engages with the wheel 1°,
the wheel 3 engages the wheel N. the wheel 4 engages the wheel 2, the wheel 5
engages the wheel, the wheel engages the wheel 4, the wheel Vengages the
wheel, the wheel W engages the wheel the wheel Xengages the wheel 7, the
wheel Yengages the wheel S. the wheel Z' engages the wheel 9".
The wheels U, V, W, X¹, Y', and are each provided on one side with a series
of tappet pins A³, 1², C², D², E³, respectively corresponding in numbers to the

page_text: numerals on the discs that is to say there are ten of the said pins on each of the said
wheels. Each disc 4, 5, 6, 7, 8, 9, is provided with a radial tappet pin 1º, 2º, 3º; 4º, 5º
respectively which are in the paths of the pins on the wheels V, W, X¹, Xɩ, Z¹, and
are arranged between the numerals 0 and 1 on their respective discs. Pawls D
engage the wheels V W X Y and Z and serve to prevent the same from turning
in a reverse direction from that indicated by the arrow in Figure 20.
A sleeve 2 extends from outside of wheel 2 to which it is firmly secured; the
said sleeve is loose on shaft T and at its outer end has firmly secured to it a spur
wheel 1 which is exactly similar to its fellow wheel 2".
A sleeve 3d extends from the outside of wheel 4 to which it is firmly secured; the
said sleeve is loose on shaft T' and at its outer end has firmly secured a spur
wheel 3 which is exactly similar to its fellow wheel 4”.
A shaft F is arranged lengthwise between the standard plates and parallel with
and at a suitable distance in rear of and below the shaft T; on this shaft F (see
Fig. 15) is loosely mounted a short sleeve 4 which has twelve ratchet teeth, the
width of which is equal to the length of the bank No. 1. Rigidly secured to the
said sleeve is a spur wheel Q which engages with a similar spur wheel 1 on
the shaft T causing sleeve 2d to rotate when spur wheel 2b attached to end of
same will engage with spur wheel 1 hence when rotary motion is imparted to the
said sleeve 4d the disc No. 1 will be turned. Loosely mounted on the same
shaft is a sleeve G³, shown clearly in Fig. 17, which has twenty teeth, and its
length is the length of bank No. 2 and bank No. 3 rigidly secured thereto is a
spur wheel H2 Figs. 7 & 17 which engages with a similar spur wheel 5" Fig. 2,
on shaft T the latter wheel engages the wheel 3* hence when rotary motion is
imparted to the said sleeve the disc 3 will be turned.
Arranged at a suitable distance above the shaft F and parallel thereto is a
shaft on which are loosely mounted a pair of ratchet sleeves L³ and M³ as
shown in Figs. 14 and 16 the ratchet sleeve L³ is provided with ratchet teeth
twelve in number also a spur wheel N³ that meshes with a spur wheel 3 which
is attached to a sleeve 3d on shaft T hence when rotary motion is imparted to
the said sleeve L the dise 2 will he turned, the sleeve Me is provided with ten
ratchet teeth also a spur wheel R³ said spur wheel being secured firmly in the
centre of said sleeve as shown in Figure 16.
Loosely mounted on shaft A' Figs. 2, 3, 7 & 12 is a rocking detent T that has
a horizontal engaging lip Us of suitable length. From one end of the detent
projects an arm V2. A spring W is attached to the shaft there is also a cross
bar H from end to end of the detent T2 and at a point about midway between
the ends of the rocking detent and the free end of the spring which bears against
the rear side of the bar H and hence moves the same normally in one direction.
A pivoted dog X is normally held in engagement with the arm V3 by a spring Y
and at the inner end of the dog is an arm which is in the path of a tappet pin A³
that projects from the ratchet sleeve L³ at one end thereof as shown clearly in
Figs. & 14. A spring controlled pawl 133 Fig. 7 engages the said ratchet sleeve
to prevent the same from rotating in a reverse direction.
On a suitable shaft 17 as shown in Figs. 2, 5 and 11 is loosely mounted a
rocking detent D³ which has a horizontal engaging lip E of a suitable length and
from one end of said detent depends an inclined arm F3. A spring is attached
to the shaft B7 and its free end bears against the rear side of the lip E3 and tends
always to move the detent in one direction. A spring controlled dog H³ Fig. 5
normally engages and holds the arm Fa and the arm of the dog is in the path
of a tappet pin K that projects from the wheel H at one end of the ratchet
sleeve G². A spring pressed pawl L³ engages the said ratchet sleeve and holds the
same against reverse rotation.
On a suitable shaft C7 as shown in Figs. 2 and 13 is loosely mounted a rocking
detent D which has a horizontal engaging lip 7 of a suitable length and from
one end of said detent depends au inclined arm F7. A spring G is attached to
the shaft C7 and its free end bears against the rear side of the lip E7; and moves

page_text: the detent normally in one direction. As shown in Fig. 7a spring controlled dog H²
normally engages the arm F and the arm of the dog is in the path of the tappet
pin K which is shown in Fig. 15 projects from the spur wheel Q At one end of
the ratchet sleeve 4d a spring controlled pawl engages the said ratchet sleeve and
holds the same against reverse rotation.
A substantially semi-cylindrical ratchet tumbler sleeve M³ is loosely journalled on
a shaft and has a series of ratchet teeth 3 say eight in number which extend its
entire length and are connected with the shaft. That side of the tumbler which is
provided with ratchet teeth is necessarily heavier than the other or cut away side
thereof, and therefore the ratebet tumbler is normally in position as shown in Figures 4
and 10 on the centre of the cut away portion of the ratchet tumbler is a semi-circular
web or flange 13 which is provided with ratchet teeth 13 as shown in Figure 7.
Arranged on the same shaft with tumbler 3 are three similar ratchet tumbler
sleeves TS3 and Q³ the required lengths for their respective banks as shown in
position in Figure 4.
The normal position of the said ratchet sleeves M³, T3, S3, and Q is shown in
Figures and 10. When any one of the finger keys X3 of any of the banks 1, 2 3
and 4 is operated the teeth 13+ on the rear side of the ratchet bars 5 6 7 and 8 will
engage with teeth 03 of the said ratchet tumbler sleeves; hence the teeth 1" on the
front side of the ratchet bars are kept in engagement with their respective ratchet
sleeves M L and G until the full stroke has been made when the teeth O of the
ratchet tumbler sleeves M³ T³ ³ and Q³ will be exhausted and the weight sido of
the said ratchet tumbler sleeve will be on the top side, and the sudden impulse
given by the upper movement of the said ratchet bars will upset the said tumbler
sleeves and immediately give freedom to the said ratchet bar, allowing the same
to descend to its normal position, when the said weight ratchet tumbler sleeve will
also come into its respective position.
Gravity pawls C as shown in Figure 4 engage the flange or web ratchet teeth Ra
of the respective tumblers the function of the said tumblers will appear hereinafter.
On a suitable shaft V3 are pivoted four banks of keys 1, 2, 3, and 4 there being
one key in bank 1' and eleven keys in bank 2 and nineteen keys in bank 3 and nine
keys in bank 4 and the said keys of each bank being numbered consecutively as the
following: Bank 1, one half and 0 or zero only, bank 2 from 1 to 11 bank 31
from 1 to 19 and bank 4 from 1 to 9.
Hubs or sleeves W³ are formed on the arms of the finger keys which bear against
each other end to end and serve to space the said finger keys to the necessary distanco
apart.
The inwardly extending arms X³ of the finger keys pass under the rod Z which
serves to connect the weight arms X the said arms X extending to within a short
distance of the back Y3 of the case.
The said back is screwed in place by screws or other suitable means and is removable.
from the case.
Each finger key is independent of all the others and forms a lever of the first order.
Four series of vertically movable ratchet bars 5, 6, 7 and 8' are maintained in
position by guide bars Y3 or other suitable devices.
There are as many of the ratchet bars as there are finger keys and each ratchet bar
is pivoted at its lower end to the rear end of the arm of its respective finger key
by means of a pin 3 which operates in a slightly elongated slot A Fig. 3 made
iransversely in the ratchet bar.
The ratchet bars are arranged and maintained at a slight distance in front of the
ratchet tumbler sleeves and each ratchet bar has on its rear side a series of ratchet
teeth 1 Fig. 3 which correspond in number to and are adapted to engage the teeth 03
of the ratchet tumblers when the ratchet bars are moved upward.
The upward guide bar Y has on its front sides a series of notches C which receive
the rear sides of the ratchet bars and maintain the latter at the required distance
apart and the inner sides of said notches are inclined as shown at D Figure 10. On
the rear side of each ratchet bar near the upper end thereof is an inclined offset

page_text: cam E4 which is adapted to engage the inclined side D' of its respective guide notch
when the ratchet reaches the lower limit of its movement, and thereby move the upper
end of the ratchet bar forward and move its ratchet teeth F' forward laterally into the
path of its respective ratchet sleeve.
The ratchet teeth F' of the ratchet bars of each bank of finger keys vary in number
and correspond to the value of the numerals on the said keys; that is to say, taking
bank 2 for example if the finger key be numbered 11, the ratchet teeth of the
ratchet bar attached to said finger key will be 11 in number, if the finger key be
numbered 10 the ratchet teeth F of the ratchet bar attached to the said finger key will
be ten in number and so on.
'
The ratchet teeth F of the bars of each bank of keys are adapted and designed to
engage different ratchet sleeves. In other words the teeth on the ratchet bar 5f
attached to the bank of keys 1 are arranged to engage and rotate the sleeve 4ª, the
teeth on the ratchet bar 6 attached to bank of keys 2 are arranged to engage and
rotate the sleeve L and the teeth on ratchet bar 7 attached to the bank of keys 3' are
arranged to engage and rotate the sleeve G2, and the teeth on ratchet bar St
attached to the bank of keys 4 are arranged to engage and rotate the sleeve M²;
hence the said ratchet teeth are differently located on the different sets of ratchet
bars.
At the lower end of each set of ratchet teeth F is a shoulder or stop G4 which
by engaging its respective revoluble ratchet sleeve when the ratchet bar reaches the
upper limit of its stroke will absolutely prevent further rotation of the said sleeve
and hence prevent the numbered discs geared to and operated by the said sleeve from
moving too far and registering a wrong number.
At the upper end of each ratchet bar 5 is a forward extending arm 1 and
pivoted to the front end thereof is a depending link arm 1ª each of the said link
arms has an offset shoulder H on its front side near its lower end adapted to be
engaged by the lip of the rocking detent E7 and on the rear side of each of said link
arms at a suitable distance from the lower end thereof is a shoulder I which is
adapted to engage a tooth on the sleeve L as hereinafter more fully described.
A spring K attached to each arm I has its lower end bearing against the rear side
of one of the link arms the function of the said springs being to normally hold the
link arms forward in position to cause their shoulders 1 to be thrown out of engage-
ment with the ratchet sleeve L³.
At the upper end of each ratchet bar 6 is a forward extending arm 2 and
pivoted to the front end thereof is a depending link arm 2h; each of which link
arms has an offset shoulder L on its front side adapted to be engaged by the lips of
the rocking detent T and on the rear side of each of said link arms at a
suitable distance from the lower end thereof is a shoulder M' which is adapted to
engage with the ratchet sleeve Gº.
At the upper end of each ratchet bar is a forward extending arm 38 and
pivoted to the front end thereof is a depending link arm. Each of the link armis
has an offset shoulder Q on its front side adapted to be engaged by the lip of
the rocking detent D³ and on the rear side of each of the said link arms 3 and at a
suitable distance from the lower end thereof is a shoulder Q5 which is adapted to
engage with the ratchet sleeve M².
The ratchet bars 8f or those attached to the last bank of keys are not provided with
link arms such as those herein before described but at the upper end of each of the
ratchet bur 5, 6, 7 and 8 in a rearward extending arm
In the front side of the upper portion of the case is an opening the entire
length of the case, as shown in Figures 1 and 6 the said opening is covered with
transparent glass. Arranged behind said opening and in line with the respective
banks are four series of tablets or indicators 1m 2, 3 and 4" he said tablets being
arranged in oblique lines and therefore partially behind each other to effect the
necessary economy of space, and enable them to be compactly disposed in the
case, and to be presented at said opening when so desired. The said tablets are
дumbered according to their respective banks and finger keys. In bank 1' there is

page_text: only one tablet required as there is only one key and one ratchet bar, and said tablet
is numbered one-half indicating half pence as shown in Figure 2 to correspond to the
finger key of the respective bank.
The tablets in line with bank 2 are numbered from one to eleven consecutively
to correspond to the numerals or values on the second bank of finger keys 2 and
indicate pence.
A similar series of tablets are arranged in line with the third bank 3′ and are
numbered from one to nineteen consecutively and indicate shillings and correspond to
the numerals or values on the third bank of finger keys 3.
A similar series of tablets are arranged behind said openings and in line with
ratchet bars of bank 4 and are numbered from one to nine respectively and
indicate pounds to correspond with the numerals or figures of the finger keys in
the fourth bank 41.
From the foregoing it will be understood that the highest value or sum that
can be indicated by the tablets 1 2" 3" and 4" when the tablet of highest value of
each series is presented behind the respective openings is 10 pounds 19 shillings and
eleven and a half pence the sum appearing thus £10 19s. 11d. arranged on the
upper portion of the case as shown in Figure and below the opening. are four
plates the width of each bank, and having the words pounds, shillings and pence and
half pence written thereou; hence the value is given to said tablets presenting them-
selves before the said name plates.
Arranged from end to end of the case and at a suitable distance below the
frames herein before described are a pair of horizontal guide bars R. In the
openings in the said guide bars are arranged four sets of vertical tumbler rods
12 and 4 to which are arranged and firmly secured the tablets or indicators
herein before described.
The numbers of the tumbler rods, tablets or indicators ratchet bars and finger
keys are equal.
The tumbler rods are in the same vertical planes with the arms № of the
ratchet bars and thereby when each of the said ratchet bars is operated by a finger
key, its arm N as the ratchet bar rises strikes the lower end of its respective tumbler
rod and thereby causes the appropriate tablet, corresponding to the value of the sale
or sum to be noted to appear before the opening in the case.
Springs S are coiled on those portions of the tumbler rods between the guide bars R+,
and the lower ends of said springs bear on the collars T on the said tumbler rods and
thereby force the latter down to their normal position.
A gong or bell U Figs. 7 and 19 is mounted in one end of the frame F and a
pivoted hammer Y is adapted to strike and sound the same, the said hammer has a
vertical arm Wagainst the rear side of which presses a coiled spring K
A trip bar Y Figure 5 is arranged lengthwise in the case and has vertical arms +
at its ends which are pivoted to the standard plates and serves to suspend the trip bar
and the spring B bears against the rear sides of the arms 7 to keep the latter norinally
in engagement with the studs.
The vertical-spring-pressed arm of the hammer engages the rear side of the trip bar
and the front side of the latter is inclined or bevelled to form a cam face ( which is in
the paths of the collars T.
When a finger key is depressed to record a sale and its ratchet bar forces up one of
the tumbler rods the collar on the said rod as it rises engages the cam face of the trip
bar and moves the latter rearward against the resistance of the spring and causes the
said trip bar to impart a sudden movement to the hammer, and thereby cause the
latter to sound the gong or bell.
The force imparted by the finger key to the ratchet bar is sufficient to cause the
latter to strike the lower end of the tumbler rod with such force as to drive the
collar on the tumbler rod upward entirely across the face of the trip bar and to cause
the latter to operate the hammer as before stated.
As soon as the collar moves up beyond the trip bar, the spring of the latter forces
it back under the collar, thereby retaining the latter and its tumbler 1od at the upper

page_text: limit of their stroke and consequently the tablet or indicator arranged and secured to
the upper end of said tumbler rod will be maintained in such a position as to display
its value before the appropriate opening until another finger key is operated for
recording another sale.
When this is done the instant the next ascending tumbler rod collar engages the trip
barand the latter ismoved rearward the collar onthe tumbler rodwhich has since the last
sale been supported in an elevated position will be released when its spring will
instantly force it down to its normal position and its fellow tumbler rod with tablet or
indicator will return to its normal position out of sight, to make way for the tablet
announcing the amount of the most recent sale.
The operation then of the sales registering mechanism is as follows:-
Before the initial operation of the machine all the discs 1, 2, 3, 4, 5, 6, 7, 8 and 9
must be turned with their 0 or zero marks opposite the opening P and this may be
effected by applying the wrench or key I to the squared end H of shaft G and
turning said shaft in the direction of the arrow in Figure 26 until the shoulders of
offset by engaging with the pins L' range all the 0 marks of the discs in line with
each other and with the openings Pl.
We will assume that the first sale that is made is of the value of one half-penny.
The salesman depresses the key of the bank 1 and by so doing causes the ratchet bar
attached to said key and having six teeth which represents one half the circum-
ference of the ratchet sleeve 4 to ascend and while so doing engages the ratchet
sleeve 4 and turns the same on its shaft through a space equal to the width of six
teeth or one half the circumference this sleeve being geared to the disc 1 by the
wheels Q1 2 1 1ª cause the disc also to rotate through the same proportions of its
circumference and thereby presents the number indicating one half penny to the
appropriate opening P¹. At the same instant the said ratchet bar operates the
tumbler rod connected to the tablet in series 1 having the number and rauses
the said tablet to be moved so as to be displayed through the opening I and before
the plate marked half-peuce and retained there in the manner before described;
and the bell or gong is rung as also before described.
The same initial impulse of the finger key which operated the ratchet bar and
registering mechanism will also cause the bar Z to rise and lift the weight arms X¹
and hence cause the right angle tappet arms to draw the rods R upwards and cause
the said rods to disengage the hooks from the studs I when the springs K instantly
throw the shield plate E open and the drawer opens in the manner before described
to receive the cash.
Immediately the salesman removes his finger from the key by causing the rod Z to
depress the inner end of the finger key the weight arms return the finger key to its
normal position and cause the ratchet bar to descend with it.
When another sale of the same value as the aforesaid one (a half penny) is made,
the ratchet sleeve 4d will effect a complete revolution the tappet pin Fig. being
in engagement with the arm 1 of the dog H as before stated will depress the said
arm and cause the dog to release the arm of the rocking detent D'when the spring G
will instantly move the said detent rearward.
On the succeeding descent of the ratchet bar the said detent will engage the link
arm attached to said ratchet bar and said link arm will be moved rearward thereby
against the resistance of the spring K and the shoulder I of the said liuk arm will
engage one of the teeth of sleeve L² geared to the pence disc 2 by the mechanism
herein before described and as the ratchet bar and link arm complete their descent the
shoulder I of the link arm will rotate the sleeve L through a space equal to one
twelfth its circumference and hence cause the pence disc 2 to turn through one twelfth
of a revolution from 0 to 1, and present the latter number to the appropriate opening I'
and dise 1 having made a complete revolution as before stated will present 0 to zero
to the appropriate opening
The shape of the shoulder I is such that as soon as it has moved the sleeve Lª one
space the next succeeding ratchet tooth of the said sleeve will engage the rear side of
the link arm and push the shoulder I thereof out of engagement with the said

page_text: sleeve L and hence the latter will be only moved the required distance and as the
link arm continues to descend after thus disengaged from the sleeve L³ its offset
shoulder or cam I will engage the lip E7 of the detent D and in moving down
across the said lip will return the said detent to its initial position shown in Figure 7
and cause its arm F to be again engaged by the dog H7 which will retain the rocking
detent D' in its initial position until the sleeve Lª has been moved through a complete
revolution.
From the foregoing it will be understood that as often as the operation of the half
pence key exceeds two the sleeve L³ will be automatically operated as before described
and will cause the pence disc 2 to move one space and present the next highest number
to the appropriate opening P.
When a sale in pence is effected say a sale of the value of 6 pence the operator
depresses the appropriate key having the number 6 in bank 2 and thereby causes the
ratchet bar 6 to operate the sleeve through a space equal to one half of its circum-
ference and consequently the pence disc 2 will be moved the corresponding distance
by the gear wheels № 36 4 and 2 respectively which connect it to the sleeve L.
It has been assumed that the said dise 2 has already been moved one space by two
previous operations of the half penny key in bank i' as the value of the said two
operations are equal in value to the sum of one penny which has been carried over to
the disc 2 as hereinbefore described.
Consequently the six spaces through which the said dise 2 is now turned by the
aforesaid appropriate key the ratchet bar of the bank 2 will cause the number seven
or the sum of 6 twelfths plus one twelfth to appear on said disc 2 through its
appropriate opening P¹.
It is understood from the description herein before given of the tablets or indicators
that at the appropriate opening one of the latter will be displayed.
Whenever a finger key of any bank is operated the highest number that may be
registered by the discs 1 and 2 is eleven and a half peace or eleven pence half penny;
with the Figures 11 and displayed through the openings.
Each time that the sleeve G is caused to make a complete revolution either by the
ratchet bars attached to the keys or by the link arms of the ratchet bars attached
to the keys 2 that is to say either by registering shillings or pence the tappet
pin K3 will engage the arm of the dog and cause the latter to disengage the
arm of the rocking detent 13 and consequently on the succeeding descent of
one of the ratchet bars 7 the said detent will engage the offset shoulder Q³ Fig. 5
on the link arm 3 attached to the said ratchet bar and the said link arm will be
carried rearward thereby against the resistance of its spring and the shoulder Q³ of
the said link arm will engage one of the teeth of the ratchet sleeve M² geared to the
pounds dise by the mechanism herein before described and move said sleeve Mone
space and thereby operate the disc 4 one space and cause the next highest number
to appear before the appropriate opening P³.
When a sale of the value of one or any number of pounds less than ten is effected
the salesman depresses the appropriate finger key in the bank 4' and causes the
ratchet bar S attached to said key to partly turn the ratchet sleeve and thereby
rotate the disc 4 the required number of spaces to indicate the sum of sales in pounds
previously made plus the amount in pounds of the sale just being effected.
When the sum of all the sales registered is more than £9 19s. 11d. the disc 4
indicating pounds will be turned to such a position as to cause its pin le to engage
one of the pins a of the wheel V₁ and move the latter one space and hence cause the
said wheel which meshes with the wheel 5* to move the latter and its dise 5 one space
and thereby cause the figure 1 indicating tens of pounds on said dise to appear before
the appropriate opening P.
And so on until the said disc 5 has been caused to make a complete revolution.
From the foregoing it will be understood that the highest amount the discs 12
34 and 5 are capable of registering is £99 19s. 11d. and that this number will
be registered by a single revolution of the disc 5. At each subsequent revolution of
said disc 5 its tappet pins 2 will be caused to engage one of the pins 13 on wheel Wi

page_text: and move the latter one space and hence cause the said wheel which meshes with
the wheel G to move the latter and its disc i one space and thereby cause the
appropriate number on the said disc indicating hundreds of pounds to appear before
the appropriate opening P"; and so ou until the said disc 6 has been caused to make
a complete revolution.
The highest amount that the said dises 12345 and 6 are capable of registering
is £999 19s. 11d.
At each subsequent revolution of the dise 6 the tappet pin will be caused to
engage one of the pins of the wheel X and move the latter one space and hence
cause the said wheel which meshes with the wheel 7" to move the latter and its dise T
one space and thereby cause the appropriate number on said dise indicating thousands
of pounds to appear before the appropriate opening P".
The highest amount that the discs 1 2 3 4 5 6 and 7 are capable of registering
is £9,999 19s. 11 d.
At each subsequent revolution of the dise 7 its tappet pin 4 will engage one of the
pins D on wheel Y and move the latter one space and hence cause the said wheel
which meshes with the wheel Sa to remove the latter and its dise S one space and thereby
cause the appropriate number on the said dise indicating tens of thousands of pounds,
to appear before the appropriate opening Pl.
The highest amount that the said dises 12345 G7 and S are capable of registering
is £99,999 19s. 11.
And at each subsequent revolution of the disc S its tappet pin 5 will be caused to
engage one of the pins of the wheel Zand move the latter one space hence cause
the said wheel which meshes with the wheel 9 to move the latter and its disc one
space and thereby cause the appropriate number on said disc indicating hundreds of
thousands of pounds to appear at the appropriate opening ".
The highest amount that the discs 12345678 and 9 are capable of registering is
£999,999 19s. 111d. but by increasing the number of discs and the operating wheels
and pins the machine may be adapted to register sums up to any amount.
From the foregoing description it will be clear that four sums exclusively in pounds,
shillings, pence and half pence may be registered simultaneously by depressing the
appropriate finger key of each bank.
A machine constructedwith four banks of keys such as is shown in the accompanying
drawings is capable of registering at a single operation any sum less than ten pounds,
nineteen shillings and eleven pence half penny, but by increasing the numbers of the
banks and ratchet sleeves and ratchet bars, link arms and detents the mechanism may
be rendered capable of registering a sum of any desired amount.
As shown in Figure S on one of the standard plates is pivoted a detent D having
a squared notch at the free end which engages the squared end H of the shaft Gand
thereby prevents the shaft from rotating, excepting when the said detent is disengaged
from the shaft and the latter rotated by the wrench key I to set the dises to the zero
or nought point as before stated.
It is of importance to prevent more than one key of each bank from being operated
at any time for the reason that the ratchet bars have varying numbers of teeth, and
all the ratchet hars of one set operate the same sleeve which is geared to the indicating
dise and therefore, if two keys of a bank were depressed at once, only the key
operating the ratchet having the largest number of teeth would be effective in
operating the registering mechanism and the value of the other keys would be lost
and hence the efficiency of the mechanism would be impaired.
Means have been devised to prevent the registering of more than one key of each
bank at the same time: and the following is a description thereof:-
A rectangular open frame E shown most clearly in Figs. 4 and 9 is arranged in
the case near the rear side thereof, and extends from one standard plate to the other.
The said frame is divided into as many divisions as there are banks of keys excepting
the bank as there is only one key in that bank as is shown in Figure 2: by means
of vertical slots (the rear ends of the arms X of the finger keys extend through the
said divisions and at the ends of the latter are stops or studs I³. Pivoted at the

page_text: upper side of each division of the frame are a series of ten hangers 1 the lower ends
of which extend into the spaces between the armis X³ there being one of said hangers
between each pair of said arms and the said lower ends of the hangers are bevelled ou
the opposite sides to a downwardly extending point. The upper ends of the hangers
are gradually narrowed as shown and the combined width of all the hangers in each
division plus the width of one of the key arms is equal to the space between one
pair of stops or studs H³.
Hence when the rear end of one of the finger key arms is moved upward when
the key is depressed, the said arm moves the hangers laterally and the latter opens
only a sufficient distance to clear the said arm before they come in contact with stops
or studs H5 and consequently render it impossible to operate another key of the same
bank; the division herein described is that of bank 2 and shown in Figure 4.
The division in bank 3 being of greater width requires a greater number of hangers
as will be seen in Figure 4 and each division according to its number of ratchet bars
and finger keys.
On the rear side of each hanger at a suitable distance from the lower end thereof is
secured a cross cleat K³which cross cleat serves to thicken the said hangers, and prevents
them from overriding each other in the event of their pivot connections working loose.
Arranged across the case near the rear side thereof is a lock plate L which is provided
with a pivot or pivots M³ that engage bearings in the standard plates. The said lock
plate is arranged at a slight distance in rear of the frame E and has a depending
Hange N and the inclined offset 0³, the latter extending towards the frame E and
the said flange N of the lock plate has its lower edge in a plane slightly higher than
the upper sides of the finger key arms when the latter are at rest. The flange N³ is
below the pivot M and the offset 0 is above the same. A spring Fig. 7 bears
against the rear side of the lock plate at a point near its centre and normally retains
the lock plate in position shown in Figure 7 with its flange N inclined rearward a
sufficient distance to clear the rear ends of the finger key arms.
The operation of this portion of the invention is as follows:--When a finger key of
one or more banks is depressed the inner ends of the arms thereof rise, and by engaging
the inclined offset partly turns the lock plate on its pivot, and causes the flange No
to move over the arms of the remaining keys and hence lock them and prevent them
from being operated until after the pressure on the finger keys in use has been removed
and the said keys have returned to their initial position when the springs P³ restore the
lock plate to the position it formerly occupied.
It is necessary to provide some means for indicating the number of times the
registering dises have been set to zero or nought in order to prevent tampering with
the machine. for dishonest purposes, in the event of a somewhat prolonged absence of
the proprietor and the following means have been devised for this purpose :
The shaft is provided near its squared end H',with pins R5 which project there-
from and are four in number and in line with the squared faces of the end Hi and loose
on the said shaft is a registering disc Sĩ which has a series of numbers on its periphery
from 0 to 20 or any other suitable number and has a spur wheel T with a similar
number of teeth. An opening is made in the plate to which the numbers on
the discs are successively presented. A short shaft V is secured to one of the standard
plates at a suitable distance above the shaft G¹ and on said short shaft is mounted a
revoluble sleeve W which has a series of arms or tappets or teeth X adapted to be
engaged by the pins R³ and a pinion Y³ with a similar number of teeth that engages
the wheel T
each time the
There being four pins R³ corresponding to the squared end
shaft is turned through one fourth of a revolution by the key or wrench I' one of
the pins engaged by one of the pins R will cause the sleeve to turn a sufficient
distance to move the disc S³ geared thereto through one space. Hence, by noting the
number seen through the opening Us when the machine is set or adjusted, the proprietor
when he returns can ascertain at a glance whether the machine has been set again
during his absence.
It is also necessary to provide some means for indicating whether the back of the

page_text: case is removed during the absence of the proprietor. To effect this a disc V Fig. 2 is
employed which is similar to the disc S and has a spur wheel Fig. 3. The numbers
on the said dise pass before an opening A in the plate R¹. A rod 136 Fig. 7 is
supported in a horizontal position by guides and extends from within a suitable
distance of the wheel to the removable rear side of the case. A coiled spring is
arranged on the rear end of the said rod and exerts its pressure between the rearmost
guide and a pin F passed transversely through the rod B. To the front end of
said rod is pivoted a pawl G which engages the wheel by gravity. When the back
of the case is removed the spring moves the rod rearward and causes the pawl to slip
back on the spur wheel 7 and engage a tooth one space in rear of the tootli it formerly
engaged and when the back of the case is again placed in position it moves the rod 13
forward against the resistance of the spring and in so doing causes the pawl to move
the wheel and disc Ve one space and thereby causes the appropriate number to
appear before the opening A6.
It is also necessary to provide a register for the lid S¹ to indicate the number of
times, if at all, the latter is opened during the absence of the proprietor. To effect
this a numbered disc H is provided which is exactly similar to the discs SV and has
a spur wheel J. The said disc is also loosely mounted on the shaft G' and its numbers
appear in succession before an opening K in the plate R. A vertically movable
rod L is guided in suitable supports M and has its upper end normally pressed against
the lid S by a spring No. To the lower end of the said rod is pivoted a pawl Os and a
spring P is attached to the rod and bears against the pawl and keeps the latter at all
times in engagement with the wheel J. Whenever the lid S' is raised the spring No
moves the rod upwards and causes the pawl to slip up on the wheel J a distance of
one tooth or space and engage another tooth thereof; and when the lid is closed it
presses down on said rod and causes its pawl to move the wheel J and disc H a
distance of one space and thereby cause the appropriate number to appear before the
appropriate opening Ko.
