COMPLETE SPECIFICATION.
Improved Apparatus for Indicating and Registering Cash Payments.
I, HENRY POTTIN, of 62, Rue St. Lazare, Paris, in the Republic of France,
Engineer, do hereby declare the nature of this invention and in what manner the
saine is to be performed, to be particularly described and ascertained in and by the
following statement.
My invention relates to improvements in the mechanism of apparatus for
indicating cash payments and to the combination with the said indicating apparatus
of registering and stamping apparatus which marks all the amounts received upon
a continuous paper band and simultaneously effects the stamping of the bill given
to customers, the said amounts being at the same time added together or totalized
by a device hereinafter referred to as the totalizer.
In iny improved apparatus a shutter covers a window or opening turned towards
the customer before each payment and behind the shutter zeros are placed. The
totalizer of the apparatus also marks zero.
When the first customer presents himself at the counter the cashier takes from
him the bill which has been given him for the articles he has purchased and operates
the pushers or buttons of the apparatus which correspond to farthings, pence,
shillings and pounds so as to mark upon the indicating apparatus the sun marked
upon the bill. This same operation changes the zero figures behind the shutter for
figures representing the amount to be paid.
The cashier then places the bill in a slot for the stamping operation which is
effected simultaneously with the registration of the sum received upon the paper
band of the registering apparatus. The cashier manipulates the operating lever so
as to cause it to move in an upward direction; the figures concealed behind the
shutter are exposed and can be read by the customer who thus checks the operation
of the cashier; the sum puid is registered and the customer's bill is stamped.
Finally the cashier depresses the lever so as to return it to its normal position; the
shutter recovers the window or opening, and behind it the zeros reappear and
the amount is simultaneously marked on the totalizer of the apparatus.
The cashier proceeds in the same manner with a second bill; the operation of the
apparatus is identically the same as above described but the totalizer at the end of
the second operation registers the sum of the two bills and so on for succeeding
operations.
.
At each manipulation a bell or gong is sounded to indicate that the cashier has
just received the amount of a bill.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawings, in which
Figure 1 is a plan view of my improved apparatus:

Figures 16 to 29 which will be referred to in the course of the description are details
of the important part of the apparatus which will enable its operation to be easily
understood:
Figures 30 to 37 are views to explain the operation of the discs of the totalizer.
The casing a of the general fraine work forms a desk on the cashier's side and is
provided with guide slots b, b (figure 1) in which the pushers or buttons.d, d can
slide, the said pushers being fixed to racks c, c arranged inside and underneath the
inclined part of the frame (figures 2 and 6).
The racks gear with the teeth e, e of discs f, which are independent of one
another and loosely mounted upon a common shaft A.(figures 2, 3, 4, 5 and 9). To
these discs f, fare fixed numbered segments f¹ in such a manner that their figures
can appear successively beneath the openings or windows b, b made in the inclined
part of the frame between the spaces occupied by the racks c, c (figure 1).
The two first segments commencing from the left are numbered from 0 to 9 and
the first corresponds to tens of pounds sterling, the second to the units of pounds,
and the third segment is numbered from 0 to 1 and corresponds to the tens of
shillings; the fourth is numbered from 0 to 9 and corresponds to the shillings. The
fifth segment, numbered from 0 to 11, corresponds to the pence and the sixth
from 0 to 3 corresponds to the farthings.
The figures of the segments f¹ serve for the cashier to indicate exactly the sum
received at each operation. For this purpose the cashier slides the push buttons d
downwards until the required figure appears through the corresponding aperture 6¹.
The drawing represents apparatus for indicating a maximum of 99 pounds
19 shillings 11 pence and 3 farthings at one operation; the totalizer adds the receipts
up to 1,999 pounds 19 shillings 11 pence and 3 farthings. The toothed discs f operate
segments, mounted loosely upon the shaft A, by means of bent rods f³ which pass
through segmental slots formed in the discs (figures 4, 8, 9, and 10).
The first disc f from the left is connected by a rod, which passes through the slots
in the other discs, with the last segment on the right; the second disc on the left
is similarly connected by rod with the segment before the last segment on the
right and so on. But the sixth or last disc f, the boss of which is loosely mounted
upon the shaft A, is directly connected by this boss with the first segment.f
(figures 4, 8, 9 and 10). The segments and the discs are connected as shewn in
inverse order, that is to say, the right hand disc with the left hand segment, the
second disc with the segment before the last etc., in order that the numerical
indications that the cashier may have to make shall appear in the same order beneath
the aperture be (figures 1 and 5) on the public side of the apparatus as well as beneath
the aperture 6, placed on the cashier's side. A movement of rotation given to one
of the discs f is accurately communicated to the corresponding segment ².
Each segment is made in one with or rigidly secured to a second segment
arranged in the same vertical plane and on the other side of the shaft A
(figures 5 and 10).
Each segment is provided upon its periphery with pins or points forming
projecting figures, such figures being arranged in the same order as those upon the
segments so that the projecting figure which appears in front of the registering
and stamping roller hereinafter described is the same as that which the corresponding
segment presents in front of the window 62.
Besides the teeth e, e with which the racks c, c engage the diees are provided
on their periphery with two other distinct. sets of teeth; one set e, el designed to
actuate a device for adding the amounts. successively receipted and the other e², e

page_text: to engage with stops for fixing the discs during the stamping operation and to
prevent the cashier from changing the amount originally indicated before causing
the totalizer to operate (figures 4, 5, 8 and 26).
A barrel spring G is provided for actuating all the mechanism of the apparatus,
that is to say, for registering the sum received, stamping the bill, operating the
totalizer, the shutter and the bell or gong and for returning the discs to zero. To
maintain a sufficient and constant degree of tension this spring is put in tension by
ineans of the operating lever g which acts upon it during its up and down noveinents.
To this end a lever having three arms g, 97, 98 (figures 4, 6 and 7) is keyed upon the
shaft or spindle g' of this operating lever which axis rotates in two bearings fixed to
the frame. To the end of the arm g two pawls g³, 9 are pivoted which said pawls,
whilst the arm g2 is raised or lowered with the operating lever, act upon the pin
plate g keyed upon the shaft of the spring G and causes it to rotate and put the
spring in tension. During the upward movement of the operating lever the
pawl g³ acts upon the pins of the plate g; when the lever g is lowered the pawl gi
acts upon the pins and causes the plate g' to rotate in the same direction as the
pawl g does, that is to say, also puts the spring G in tension.
If, by moving the lever up and down, the plate i could be caused to make a
twelfth of a revolution and the fever then return each time to the starting point. the
said plate would be caused to turn indefinitely in the same direction, that is to
say, to wind up the spring G without ever disengaging it so as to allow it to unwind;
the spring G, therefore, would be easily broken.
To avoid this I employ a device which prevents the lever g during its upward
movement from returning before having arrived at its uppermost position in which
the disengagement is effected; the same device prevents the lever g in its downward
movement from returning before having arrived at its lowermost position in which
the disengagement is effected. By referring to figure 7 it will be seen that this
device comprises. a sector go fixed to the arms g, g of the three armed lever keyed
upon the shaft of the lever g. The sector g is provided with four notches
two go, go of which face in one direction and the two others g", g in the opposite
direction.
The plate B', keyed upon the shaft B, is provided with two cams g12, g13 one
projecting upon its front face and the other upon its circumference; the cam g¹² also
serves as a stop for the double lever B.
Upon a small fixed horizontal spindle g14 two levers g1, 91, each having two arms,
are inounted loosely and superposed upon one another. The large arms of these
levers are provided with lips which constantly tend to make contact with the
periphery of the sector g under the action of spiral springs g17 attached to the
small arms of these levers. The sinall arms of the levers, are provided at their enda
with-rollers one of which faces the periphery of the plate B' and the other of which
is slightly in advance of this plate. When, the operating lever is in its lower
position the arrangement is as shewn at figure 6; the roller of the upper
lever g15 rests at this instant upon its cam gi and the roller of the lever g¹ rests
upon the periphery of the plate B'; the large arm of the lever gls is raised so that
the sector g' can turn from left to right; the operating lever can then be raised but
after a twelfth of a revolution the lip of the large arm of the lever g6 drops into the
first notch g" and prevents the lever g from moving back. It is therefore,
necessary that the lever should finish its upward stroke before being able to return.
On reaching the end of its upward movement the lever g effects the disengagement
and the plate B turns with the shaft B for a quarter of a revolution; in this
movement the cam g" leaves the lever g" and the cam g raises the roller arranged
on the end of the sinall arm of the lever g (figure 7). The lever g can then be
moved downwards but after a twelfth of a revolution the lip of the lever g engages
with the notch g10 and prevents the return of the lever g and so on. In both cases
therefore, the lever must be. pushed to the end of its stroke whereby the necessary.
disengagement will be always effected and the spring g will not be rendered liable to
rupture.

page_text: The rotation of the spindle of the spring G in the opposite direction is prevented
by the pawl.g" (figures 6 and 7).
Upon the spring barrel G there is fixed a toothed wheel G, which by means of
a train of wheels, constantly tends to rotate the driving shaft B, upon which are
keyed nine cams (see figure 29), operating the various mechanisms of the
apparatus.
The shaft B, however, is prevented from rotation except when required and is
then only allowed to rotate to a limited extent by means of a special device.
At the end of the shaft B and on the same side of the apparatus as the lever g
there is keyed as above described the plate B' which is provided with a projecting
stop g upon its front face and with two cams g12 and 918 one of which projects
from its front face and the other from its periphery. It has already
been shewn that the cams g12, 13 operate rollers carried by the small
arms of the levers gis, g' (figures 6 and 7). The cam g" which projects from
the front face of the plate B' has still another function, that is to say, it forms a stop
and together with the stop assists in arresting at the required moment, the
rotation of the driving-shaft B.
A lever B², capable of oscillating around the fixed pivot B and placed in front of
the plate B, is provided at its upper part on the side opposite the plate B with a
pin B which according to the position of the lever Be is in the circular path of the
stop cam gor in the circular path of the pin g20. The lever B2 is held in
each of its two extreme positions by a' strong spring B³ as clearly shown
in figures 6 and 7.
When the apparatus is at rest the lever B2 is in the position shewn in
figures 35 and 36 (which are respectively end and side elevations) and the
stop cam ga rests against its pin B³.
If the operating lever keyed upon the shaft g' be raised it causes the
three armed lever g; g, and g keyed upon the shaft g' to rotate from left to right and
when the said lever g has nearly reached its uppermost position the arm g of the
three armed lever strikes a lug B on the lever B2 and moves this lever slightly from
right to left; during this movement the pin B escapes from the stop gi and the
plate B is liberated; the shaft B being subjected to the constant action of the
barrel spring G is then rotated, but the lever B has been carried by the arm g' to a
position such that its pin B5 is situated in the circular path of the stop g20 of
the plate B so that as soon as this stop g20 strikes the pin B the plate B stops.
The stop g being placed behind g upon a radius making an angle of 90° with the
radius passing through the said stop gl it follows that the plate B' has moved
through a quarter of a revolution. The parts of the mechanism are then in the
position shewn in figure 37.
If the operating lever. be now pulled downwards into its lowermost position the
three armed lever g, g', g is rotated from right to left and when the said lever g
has nearly reached the end of its movement the arm gs strikes the lug Bo on the
lever B2 and causes this lever B to rotate from left to right. so as to return it to its
initial or normal position.
During this movement the pin B' is released from the stop g20 and again moves
into the circular path of the stop g12; the plate B' being liberated the shaft B
rotates and therefore moves three quarters of a revolution so as to bring everything
into the initial position.
In order to explain the transmission of movement from the driving shaft B to
the different mechanisms I will take the different parts in the order in which the 5
operations are carried out.
When the lever g is raised as above described release takes place and the shaft B
rotates for a quarter of a revolution. This rotation produces four results; it fixes
the toothed discs f, mises the shutter i, registers the amount upon the paper sheet
of the registering device and stamps the bill and finally brings the totalizing 5
apparatus into operative position.

page_text: To fix the toothed dises f the enn H keyed upon the shaft B operates the following
device.
A fixed spindle & supported in the frame of the apparatus parallel to the shaft B
and extending over the whole length occupied by the discs f supports a bar bent
at its two ends and pivoted upon the said spindle (figures 4, 5, 26 und 27). A spiral
spring constantly tends to rotate this bar in a predetermined direction but the
roller stop fixed upon, or made in one with, the bar and which strikes against the.
cain H limits this movement. Upon the bar are fixed springs ht which engage
with pins or projections formed on beut or hell-crank levers k, mounted loose
npon the spindle A and independent of one another. The springs A, therefore, tend
to constantly force the rollers A, A which form the ends of the levers into
engagement with the spaces between the teeth e of the dises f. But when the
lever g is in its lower position-the action of the springs is sufficiently weak to allow
the dises to rotate. When, on the contrary, the lever g is in its upper position the
cam H acts with considerable leverage upon the stop ha which is rigidly attached to
the bar ', the said bar is then raised towards the horizontal arms of the levers h³.
The springs & are bent still more and press the rollers h with considerable force in
to engagement with the teeth e. On the other hand the bar A is in such a position
that the levers A can be no longer lowered sufficiently to enable the rollers to he
released from engagement with the teeth. By this means the discs are rigidly fixed
in position. The two outwardly bent ends of the har h' are connected by a bar or
strip h° which extends above the horizontal arms of the levers h³ and pulls these
armus downwards so as to cause the rollers h to be completely released from the
teeth when the discs f return to zero.
To operate the shutter a cam I is fixed upon that end of the shaft B opposite to the
plate B; when the lever g is in its upper position and the shaft B rotates for a quarter
ofia revolution this cam I actuates a roller t' which is formed on the end of one of the
arms of a bell-crank lever i at the end of the other arm of which is fixed the
shutter . This shutter is therefore raised and uncovers the window b' which
faces the customer (figures 5 and 28).
To register the amount received and to stamp the bill the shaft B operates the
registering apparatus referred to above in the opening paragraphs by means of
two carns J and K (figures 11, 12 and 29).
The stamping and registering apparatus (figures 5, 11, 12, 13 and 14) comprises
two supports 3, suitably fixed in position and which carry the main pivot
spindle around which the whole of the apparatus can oscillate. This registering
device is placed in the apparatus facing a hinged door locked by means of a key. It
is held and guided by two guides, by a stop on the side of the customer and
tappets on the side of the cashier, against which tappets a jointed handle which
is kept lowered by springs, strikes. By raising the handle-and drawing it towards him
the cashier can remove the registering device from the apparatus .to renew the
roll of paper.
Upon the spindle a frame is loosely mounted the said frame serving as a
bearing for the spindles, ofthe rolls of paper, and for the guide roller
which is covered with indin-rubber. The roll of paper turns freely upon the
spindle which passes through it and this epindle is provided at one end with a
knob or button serving as a handle by means of which it can be pulled out when it
is desired to provide it with a fresh roll of paper.
The roller can also be removed by raising spring levers which normally hold
the spindle of the roller in notches formed in the frame and serving as a bearing
for the said spindle.
One of the faces of the roller is provided with matchet teeth y operated by
pawl pivoted upon the lever P. This lever, pivoted itself at one end upon thé
inovable frame of the registering device, carries at its other end a roller which
is operated by the onm K keyed upon the driving shaft B when the lever g has been
returned to its lower position. Directly after the stamping operation has been
effected as described below the roller is rotated through a certain angle through

page_text: the medium of the ratchet teeth 2 and pawl so as to feed-to the roller where the
stamping is effected a fresh surface of the band of paper . A pawls prevents
the rachet and thereby the roller from rotating backwards.
To register the amount received the roller j over which the paper band passes is
moved towards towards the segments f' carrying the figures formed of small pins and
presses this roller against the said sectors. This is effected by means of a support
fixed upon the frame and adjustable in position, which support carries a
roller operated by the cam J keyed upon the driving shaft B when the lever
arrives at its upper position and when the shaft Brotates for a quarter of a
revolution. The whole of the frame turns around the axis and the roller over
which the band passes assumes the position shewn in dotted lines in figure 12 and is
pressed against the pins upon the segments which perforate the paper with the amount
indicated in the window of the apparatus (figure 12). A spring returns the
frame after each operation to its norinal position as soon as the cam J ceases to
act upon the roller j and the perforated paper band is then fed on to the roller j by
the pawl as above described. A spring presses against the surface of the roller s
so us to forin a brake and prevent the said roller Trom rotating too quickly as the
paper band is unwound.
To stamp the bill the cashier passes it at the beginning of the movement of the
lever g into the slot j formed in the side of the apparat ns (figures 5 and 12). It is
then guided by the lingers between which pass the dises / carrying the figures.
These fingers also serve to.disengage the bill from the pins after they have perforated
it.
To explain now how the totalizing apparatas operates that is to say nasummes its
operative position when the lever g has arrived at its upper position or mechanically
effects the addition of the last amount registered to the previous total when the
lever g is returned to.its lowermost position, I will describe the principal parts of this
totalizing device.
The totalizing device comprises six pinions (figure 15) adapted to engage at a
predetermined instant with the teeth e of the discs (figure 25). These pinions are
to this end placed respectively in the same vertical plane as the discs with which they
are to engage (figures 3, 15, 24 and 25). The last pinion 4, that on the right, has
not a toothed dise f in connection with it (figures 2, 3, and 15). All these independent
pinions are mounted loosely upon the saine shaft I parallel to the driving shaft B
and resting upon two end supports and intermediate supports which hold it
rigidly (figures 2, 3 and 15). All the supports are fixed upon a bar 1 furnished
with a pivot at each end and resting in two supports l', secured to the frame
(figures 15 and 23).
Upon the bar Li there is fixed a lever 12 having a roller 13 (fig. 22) upon which the
cam C, keyed upon the driving shaft B, acts when the operating lever g is at its
highest point. At this instant the bar L' rocks upon its pivots and the pinions
engage with the teeth e on the discs f (figure 25). As soon as the cam C moves
away from the roller. (fig. 22) a spiral spring secured to the frame and to the
lever which is rigidly fixed to the bar I returns this bar to its normal position and
disengages the pinions from the discs f.(figure 24):
. Each pinion is formed in one with or has rigidly attached to it a cam m
(figures 15 and 20) and a cylinder or barrel m' provided with ratchet teeth m, All
the groups formed of a pinion 1, a cain m and a barrel m', are independent of one
another and they are all-mounted loosely upon the common shaft L (figure 15).
Each barrel m' is furnished with a spiral spring m³ one end of which is fixed to a
toothed sector m' and the other end of which is secured to the barrel itself (figure 15).
Upon the nave of each toothed sector m' there is keyed a disc m which closes the
barrel on the side opposite to the cam m, upon an extension of this disc there are
fixed two hooks or pius m, m³ and each dise is provided on its free-face and opposite
the hooks or pins mo, ma with a stop s the object of which is hereinafter described
(figures 15, 16, and 30).
Upon each of the supports of the shaft L-there is screwed a double spring mone

page_text: of the arms of which is slightly sliorter than the other so as to ensure its always
operating efficiently. These springs form pawls for the ratchets m² of the barrels m
(figures 15, 24 and 25). The auxiliary pinion 1, registering hundreds of pounds, has
no cam but a barrel or cylinder me without a spiral spring (figure 15). Moreover,
the bar L' also supports two sets of devices designed to act upon the cama m and the
discs m³.
The first set of devices is composed of levers a mounted upon a spindle the ends
of which rotate in two supports screwed upon the bar 1 (figures 15, 24 and 25). An
arm of the lever n³ is keyed upon the common spindle n¹ the said arm carrying at
its end a roller which is constantly applied by means of a spring n against the
surface of a cam N keyed upon the driving shaft B (figures 15.and 16). As soon as
the operating lever g is raised the cam N. commences to rotate and presents its small
radius to the roller n. The spring a fixed to the horizontal arm a rigidly secured
to one of the levers then causes the levers n to swing until the roller again
comes in contact with the cam N which brings the levers n within the circular path
of the stops me carried by the discs m³ as shewn in figure 31.
These levers do not leave their position in the circular path of the stops m³ until
the lever g having returned to its lowermost position the pinions & bave moved away
from the discs f and are in their position of rest (figures 25 and 30). During the
two oscillations, forwards and backwards, of the bar L the spring n holds the
horizontal arm in contact with the support L' in such a manner that the levers n
follow the movement of the bar L' so that the ends of the said levers n are held
under the stops m" or at any rate in their circular path (figures 31 and 32).
The second set or group of devices carried by the bar L comprises bent or bell-
crank levers o placed in the same vertical plane as their corresponding cams m
(figures 15, 20, 24 and 25). Each lever can turn around its own axis of fixed upon
one of the supports of the shaft L and a spiral spring o2 wound around each pivot of
and one end of which is secured to the lever o (figure 15) constantly holds this lever
against the corresponding cam m. To each lever is fixed, perpendicularly to its
plane, a stop o against which one of the two pins or hooks m³, m' of the disc m
may strike during the rotation of the said disc (figures 15 and 30 to 34).
The apparatus is completed by the following device:
On the side of the pinion opposite to the discs f, that is to say, in front of these
pinions there is placed a bar p fixed in position by means of adjusting screws
(figures 23, 24 and 25). Upon this bar are fixed six fork-shaped double supports p
(figures 2, 15 and 23). Each double support pl is provided with a spindle or pivot
on which are loosely mounted two wheels one p adapted to gear with one of the
pinions and the other ps gearing with one of the toothed sectors m formed in one
with a disc m and mounted loosely upon the shaft L (figures 15, 24 and 25,
and 16 to 19).
As above described the pinions & can turn together round the pivots of the bar L.
In one of their extreme positions they gear with the toothed discs f and in the other
with the wheels p² mounted loose on their spindles or pivots (figure 24). The pinion!
for the farthings, however, does not gear with the wheel p (figures 2, 3, and 15).
The pinion for the pence, which bas twelve teeth, gears with a wheel p2 having six
teeth and rigidly connected to a wheel p³ with twelve teeth which is actuated by the
sector m having two teeth for the farthings (figure 17) in such a manner that for one
revolution of the sector m' or of the disc m' the pinion and the barrel m for the
pence makes a twelfth of a revolution, that is to say, a unit number of revolutions for
their denomination.
In like manner the pinion which has ten teeth forming the unit wheel for the
shillings gears with a wheel p2 having five teeth and rigidly secured to a wheel p³
having fifteen teeth actuated by a sector m having three teeth (figure 16). The
pinion with ten teeth for the half sovereigns or tens of shillings gears with a
wheel 2 having five teeth and which is rigidly connected with a wheel pa having
thirteen teeth and actuated by a sector m having thirteen teeth (figure 18) whereby

page_text: when the sector wanakes one revolution the pinion l'indicating the tens of shillings
makes balf a revolution. The pinion l with ten teeth for the pounds gears with a
wheel p having five teeth and fixed to a wheel p-having fifteen teeth and actuated
by a sector m laying three teeth.
The pinion with the ten teeth for the tens of pounds gears with the wheel p
having five teeth and rigidly connected to a wheel p having fifteen teeth and
actuated by a sector m with three teeth.
The pinion with ten teeth for the hundreds of pounds gears with a wheel p' with
five teeth and rigidly secured to a wheel p with ten teeth actuated by a sector m
with one tooth (figure 19) in such a manner that for one revolution of the sector mt
the wheel me for the hundreds of pounds will make a twentieth of a revolution, that
is to say, will make a movement representing a unit of its denomination.
During the whole time in which the wheels 2 are not in engagement with their
corresponding pinions & they are fixed by means of springs p (figures 21, 24 and 25)
all secured upon the same spindle p' adapted to rotate in hearings in brackets or
supports fixed to the frame of the apparatus. This spindle is provided, in addition,
with an oscillating lever pithe free end of which carries a roller p' which is inaintained
in contact with a cam P keyed upon the driving shaft B by means of a spring p³.
As soon as the pinions & leave the wheels 22 the cam P causes the springs p to come
in contact with these wheels; the said springs are released leaving the wheels p at 2
liberty as soon as the pinions I re-engage with them.
'I will now describe the operation of the totalizer.
to
When the lever g-reaches its uppermost position the totalizer is made ready to
operate as hereinbefore mentioned. The bar L' swings and causes the pinions
engage with the discs f. The levers n have been moved into the circular path of the
stops m of the discs m and one of the hooks m", m' of these discs m' strikes against
the stop os of the levers o. The springs pt then fix the wheels p and consequently
the wheels p³.
If, now, the operating lever g be lowered a cam Q keyed upon the driving shaft B
(figures 5, 9 and 10) acts upon a roller q rigidly connected to a toothed sector g
running loose upon a spindle g fixed upon the frame. The sector q in rotating
carries with it a second sector g³ mounted loose upon the spindle A of the disca fand
thereby causes a bar q to rotate in the desired direction, the said bar being fixed
upon an arm of the second sector q and being held by a second arm q loosely
mounted upon the shaft A (figures 9 and 10).
In turning, this bar y encounters successively the hooks of the registering
segments and carries with it these segments and with them the segments f and
the discs in-stich a manner that when the bar q stops moving all the discs / and
the sectors are returned to zero. Each disc has turned, during this movement,
through a space corresponding to the number of teeth representing the figure, of the
sum registered, which was indicated by the disc. Each pinion then which gears with
its corresponding dise/ turns through a space corresponding to a number of teeth
representing the figure of its denomination in the sum registered. This rotation of
the pinions and consequently of the barrels mal has for its object to put the spiral
springs of the said barrels in tensiou because at this instant the discs m³ are fixed
against the stops o³ (figures 25, 32, 33). As soon as the parts have returned to zero
the cam C leaving the roller l, the bar I is caused by its spiral spring to return the
pinions so that they leave the discs and gear with the wheels p².
в
The springs p are also drawn back so that they release the wheels p
(figure 24). "The levers a are now removed from the circular path of the stops mof
the discs ma'.
The cams m, which are rigid' with the pinions., are arranged in such a manner
that every time that any of the pinions make a complete revolution the
corresponding cans abruptly present their short radius to the arms of the bell-crank
leverno. These levers o are abruptly drawn back by their springs of and each of the
corresponding stops of describes an arc of a circle around the spindle o'. On referring
to figures 33 and 34 it will be seen that this rotation is not prevented by the

page_text: pins m, m' and that in this movement the stop-o passes between these two pins and
then assumes its initial position, that is to say, in the circular path of the pin m³.
The discs which have been released are then caused by their barrel springs to rotate
until their stops me rest upon the levers (figure 34); then when the pinions have.
rotated towards the front and the levers n have been drawn back these discs make a
complete revolution but are prevented from rotating further as each stop of exactly.
engages with the corresponding pin w" at the end of the revolution (figure 30). The
complete revolution of a disc ms has for object to cause the corresponding toothed
sector m to rotate to the same extent as they are keyed one upon the other; but in
its revolution the toothed sector m has engaged with the corresponding wheel p* and
has rotated it through a part of a revolution. The wheel p being rigid with a
wheel p, the said wheel p is rotated to the same extent and as it gears with the
pinion indicating the digit next in order above that of the pinion which has been-
taken as the starting point and as the trains of wheels have been determined there-
fron the pinion corresponding to the next digit registers its unit figure in addition.
It will therefore be seen that each time a sum corresponding to the value of the
next higher digit has been added to the same pinion this pinion will cause the
adjacent pinion representing the next higher digit to move through a space
representing unity and so on."
The totalizer can be consulted at any moment for ascertaining the total of the
amounts registered from the start, the apparatus being initially at zero.
To return the totalizer to zero after a series of operatious, at the end of a day's
work for example, it is only necessary to note the number indicated upon the
totalizer without taking note of the hundreds of pounds. The number which it is,
necessary to add to make a hundred pounds is then ascertained and registered upon,
the apparatus. After this addition all the barrels of the totalizer are at zero except:
that indicating the hundreds of pounds the number of which is increased by unity..
It is then only necessary to return to zero, by hand, the last barrel which has no spiral,
spring, this operation being easily effected by moving the operating lever so as to
disengage the pinion keyed upon this barrel from the corresponding wheel p
I may remark that, as soon as the lever g has reached its lowermost position and
as soon as the rotation of the shaft B. commences, the cam I which has raised the
shutter releases the same and it falls by the action of gravity thus closing the
window 62 which faces the customer (figure 28).
The apparatus carries a bell or gong tand a'fly (figures 2, 4, 6). The operation of
the bell is effected at the end of the operation by means of a cam T keyed upon the.
driving shaft B which raises a hammer t' and coils a spring wound round the lever,
of the said hammer t'. The cam T allows the hammer to fall at the instant that the.
shaft B finishes rotating. This stroke of the bell indicates that the cashier has just
received the amount which he has to count and to register upon the apparatus.
The fly is actuated by the toothed wheel G' of the barrel G through the medium
of cylindrical pinions r,,, of a helical wheel + and of a worm which forms its,
axis of rotation (figures 2, 4, and 5).
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, 1 declare that what I claim is:-
1. Apparatus for indicating and registering cash payments having a rack device for:
indicating the figures of the amount simultaneously to the cashier and to.the public,
the said apparatus comprising a safety device for the operation of the different.
mechanisms of the apparatus in combination with a registering and stamping device
which imprints all the amounts. received upon an endless paper band and -
simultaneously effects the stamping of the customer's receipt and the addition of the.
said amounts to the total and in combination with an improved adding or totalizing.
device giving the sums received in pounds, shillings, pence and farthings, substantially.
as described and illustrated in the accompanying drawings.
2. In apparatus for indicating and registering cash payments, of the kind described...
in claim a device for operating the various mechanisms such device comprising a
B

page_text: lever g upon the shaft g' of which is keyed a lever having three arms g, g', g
one g of the said arms serving as a pivot for two pawis g, g' which act during the
rising and falling of the lever g successively and in the same direction upon a
pin plate g keyed upon a shaft to which is fixed one end of a barrel spring G, the
two other arais g', 9 disengaging at the proper time and for the required interval a
second plate B keyed to the end of the first driving shaft B so as to enable this abaft
to rotate to the required extent under the action of a toothed wheel G' fixed upon
the barrel to which is attached the other end of the spiral spring G, substantially as
described and illustrated in the accompanying drawings.
3. In apparatus for indicating and registering cash payments, of the kind described
in claim I a safety device in combination with a lever g and with a barrel spring G,
such device comprising two levers having two arms g, mounted loosely upon a
fixed shaft and controlled by springs in such a manner that cams g12 and g of a
plate B successively prevent the lips forming the ends of the large arms of these
fevers ggs from dropping into notches g, gll of the sector whereby the required
movement of the lever g is permitted but its return is prevented in every case before
it arrives at the end of its upward or downward stroke, substantially as described and
illustrated in the accompanying drawings.
4. In apparatus for indicating and registering cash payments, of the kind described
in claim a device for locking toothed discs at the time the amount is being
registered, the said device comprising a cam H keyed upon the driving shaft B and
arranged to act upon a roller A rigidly connected with a bar A' in such a manner as
to raise this bar at the desired moment and to place it in a position such that it no
longer allows the bell-crank levers he carrying rollers & which engage with the teeth
of the discs to drop sufficiently to enable the rollers & to disengage the teeth, the
effect of the action upon the rollers h of the springs A fixed upon the bar A¹ being
increased by this means and the levers A being pulled downwards by a bar A' rigidly
secured to the bar h¹ in such a manner that the rollers A are wholly disengaged from
the teeth of the discs when this bar Aawings in the opposite direction as the discs f
return to zero, substantially as described and illustrated in the accompanying
drawings.
5. In apparatus for indicating and registering cash payments of the kind described
in claim a device for successively registering the autounts received and at the same
time for stamping the customer's bill, such device consisting of a carriage or support
upon which can oscillate a frame carrying two paper rolls and a guide roller j
covered with india rubber, the movement of oscillation being communicated to the
movable frame. by means of a cam J keyed upon the driving shaft B so as to press
an endless sheet of paper 1 and the bill between the india rubber cover j and
segments provided with projecting figures formed of pins, the feeding forward of
the sheet being effected after the perforation by means of a cam K keyed upon
the driving shaft B and which actuates, by means of intermediate levers, a ratchet
fixed upon the spindle of the roller j', substantially as described and illustrated in
the accompanying drawings.
6. In apparatus for indicating and registering cash payments, of the kind described
in claim I a device for adding the amounts received, the said device comprising a
series of spring barrels m' the Grat numbered upon ita periphery from 0 to 3 for the
registering of farthings, the second numbered from 0 to 11 for registering pence, the
third numbered from 0 to 9 for shillings, the fourth from 0 to 1 for tens of shillings,
the fifth numbered from 0 to 9 for pounds, the sixth numbered from 0 to 9 for tens
of pounds and the seventh or supplementary barrel numbered from 0 to 19 for the
hundreds of pounds, each barrel being formed in one with or secured to a toothed
pinion t and a cam m each of the six first barrels being fixed to one end of a spiral
spring m³ which is itself fixed at its other end to a device formed of a disc m and of
a toothed sector m', the whole being combined with trains of wheels which at the
required moment transmit the retarded rotation of each barrel to the next barrel to
effect the addition or totalization of the amounts registered, substantially as described
and illustrated in the accompanying drawings.
