Improvements in Indicating and Registering Mechanism.
JAMES YATE JOHNSON of No 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been
communicated to me from abroad by The Long Acre Company Limited of
No. 9 North 13th Street in the City of Philadelphia, State of Pennsylvania
United States of America and in what manner the same is to be performedi
to be particularly described and ascertained in and by the following statement :-
This Invention relates to cash indicating and registering machines of that class in
which there are employed as characteristic features a movable indicator carrying
figures in connection with a series of numbered keys, the operation of any of which
determines the extent of movement of the indicator and consequently the figure to be
exhibited or indicated.
The object of the Invention is to construct such an indicator and register which
shall be simple and economical in construction, positive and reliable in operation and
not easily put out of order.
In the accompanying drawings

register may be applied to an ordinary shop counter and in connection with the cash
drawer or till.

Figures 11 and 12 are perspective views of a part of the device.
In the drawings of the present application, each movable indicator is shown as in
the form of a flat disk or wheel adapted to rotate on a central axis and bearing upon
one face near the periphery the several spaced figures or numbers. It is to be under-
stood, however, that this particular form of movable indicator has been adopted only
for convenience of construction and it is not desired to be restricted thereto, as any
other well known form of movable indicator bearing figures and whether a wheel or
not, might be employed in its stead.
This machine is shown as provided with three indicating systems, one at the right
hand side of Figure 2 and left of Figure 3 being for the pounds, and provided with
nineteen keys and with the indicator numbered to correspond. The opposite indicating
system for the shillings is also provided with nineteen keys and corresponding
numbers on the indicator, while the third system which in this case is located below
and between the other two, is for the pence and accordingly has but eleven keys with
a correspondingly numbered indicating disk. The machine thus built can indicate
any single amount at penny intervals, up to £19 19s. 11d. and it can make totalizing
1177

page_text: registries up to any amount limited only by the number of registering wheels in
connection with the pounds indicator. In Figure I have shown the pounds indicator
as provided with three registering wheels.
Each moving indicator in any of these constructions has in connection with it, as
already intimated, a series of controlling keys numbered in correspondence with the
figures or numbers on that indicator.
Each moving indicator with its set of keys and immediate operating devices forms
a complete system in itself and may have its separate frame. In the drawings the
three indicating systems are shown as having separate and detachable frames
mounted upon a common stand S carried by a two-legged vertical post S¹, which, as
shown in Figures 1 and 2, may be mounted upon the ordinary counter (of a shop or
may be mounted upon a suitable portable box or cabinet provided or not with a till
or cash drawer K. Or the apparatus may be mounted in any suitable place with or
without the tubular post and the frames of the indicator systems may be in one piece or
several as desired.
As has already been said, each movable indicator with its set of keys and its
immediate operating devices, forms a system in itself and the following description of
one of the indicating systems will apply equally well to all, reference being had to
Figures 2, 3, 4 and 5. This last view is specifically a view of the pounds indicating
system, but it will illustrate equally well (except in the matter of numbers upon the
indicators and the registering wheels and the number of controlling keys) the system
for the shillings and pence.
A frame A of the indicator carries a central spindle, which is shown as a fixed
spindle a (Figure 5) for the rotating indicator wheel D. This indicating wheel D
carries on its front, (that is, the face of the machine which is presented to the
customer) a series of numbers any one of which will show through a suitable opening
at the proper moment in the front of the casing. It may be here noted that the front
of the machine may simply be covered by a metal sheet casing X (Figures 2, 3, 4
and 5) removable at pleasure to get at the inside works when needed. The casing X
has openings a', in it at proper points to allow the indicating figures to show through
(Figure 3) on the customer's side, while on the salesman's side there are openings
(Figure 2) for the registering numbers to show.
The frame of each system is provided at the rear with a series of transverse
elongated bearings for the reception and guidance of the several controlling keys B
which, as will be seen are arranged in a circle. The heads of the keys are of
course on the opposite side of the machine from that on which the indications are
shown to the customer in order that these numbered heads may present themselves
for the convenient operation of the salesman. Suitable spiral springs encircling
the stems of the keys in the bearings tend to push them outward and pins in the
bearings limit this outward movement. Any one of these keys when pressed inwards
by the salesman acts to engage the indicator with the operating device as hereinafter
described, and also as a stop to determine the extent of movement of the indicating
wheel through the medium of devices which will now be explained.
In machines of this character which have heretofore been constructed, the move ble
indicator has been spring impelled and the keys have been the means of retaining the
indicator in its normal position against the action of the springs and when one of the
keys has been operated the indicator would thereby be released, and at once be operated
by the spring.
In the present machine, however the springs are entirely dispensed with, and instead
thereof means are provided for imparting a positive motion to the moving indicator after
a key has been operated. The keys instead of normally restraining the movement of
the indicator against the action of the spring have under normal conditions. no
operative connection with the moving indicator, but the operation of any one of the
keys serves to throw into engagement with the indicator a device having a handle
(such as a till or cash drawer or a hand lever) so that the operator by grasping this
handle can readily impart a positive motion to the indicator and the extent of that

page_text: positive motion of the indicator is determined by the key which has been previously
operated, and which at the proper moment releases the indicator again from connection
with the positively moved device.
A gear wheel E which is shown as mounted upon the central spindle a but over a
sleeve d attached to or formed in one with the indicator (Figure 5) carries a pawl El.
This pawl when the parts are at their normal positions at rest, is in the position
indicated in full lines in Figure 4, but by the operation of any one of the keys it can
be thrown into engagement with a notch or tooth d formed in or ou, or attached to
the indicator wheel D (Figure 4).
To throw this pawl into engagement with the indicator wheel, a tripping ring or
disk F is provided which has a projection to act upon the tail e of the pawl E. A
spring e acting upon a V shaped eam upon the pawl will hold the latter in either of
the extreme positions to which it may be moved, that is, either in or out of engagement
with the indicator wheel. The tripping disk is operated by any one of the keys,
and for that purpose notches are formed in the periphery of the disk opposite the
several key stems, and on one side of each notch is an incline adapted to be acted
on by the stem of the key when the latter is pushed in (see the perspective view
Figures 11 and 12) so that the pawl tripping disk is then moved from the position shown
in full lines in Figure 4 to an extent a little less than the length of the incline. By
that movement, the pin acting on the tail of the pawl E throws the latter over
into engagement with the indicator wheel D. If now a positive motion be imparted
to the wheel E, which carries the pawl E' and which has been put into engagement
with the indicator, the indicator disk will be moved. The stem of the key which has
been pressed in has passed through the notch in the tripping disk and its end is
beyond the latter in the path of the tail of the pawl E, so that when the pawl comes
round to that key stem, it will be disengaged from the indicator disk and the latter
will stop at the determined position although the wheel E continues to revolve.
order to retain the operated key in its inward position, at least until such time as the
tail of the pawl comes round to be struck by it, the tripping disk F is also made to
serve as a locking disk by causing projections (Figure 11) on the opposite edge of
each notch from the incline to enter a notch n in the key stem when the latter is
pushed inwards to move the tripping disk, as shown in Figure 12. At the same time
the projections on the edges of the other notches in the tripping disk enter at n' under
the stems (Figure 11) and lock all the unoperated keys, so that they cannot then
be pressed inwards until the tripping disk is returned to its normal position when the
wheel E reaches the end of its first or forward revolution by a pin on the wheel
striking one end of a lever J pivoted to the casing, the other end of the lever acting
on a pin on the tripping disk to return it to the position shown in full lines in
Figurs. In order to retain the tripping disk in either of its extreme positions
and also to insure its entering the notch of the operated key, a springs, acting
on a V-shaped cam on the margin of the disk, is provided, as illustrated in
Figure 4.
In
To restore the indicating wheel to its normal position with zero showing through
the opening in the casing, a restoring pawl M is provided upon the wheel E facing in
the opposite direction from the indicating pawl E. This restoring pawl normally lies
in engagement with a notch or tooth m on the indicator disk, and when the latter
rotates in the direction of the arrow, Figure 4, with the wheel E, the restoring pawl
travels with it, remaining in engagement with the notch or tooth and when the
indicator disk ceases to move, by the disengagement of the pawl E', the restoring
pawl M then simply rides free from the projecting portion of the indicator wheel in
which the engaging notches d' and m are found. But by returning the wheel E in
the opposite direction when it has reached the end of its forward movement the
restoring paw M rides back until it again engages with the notch m in the indicator
and then it carries the latter back to the zero position from which it started. The
wheel E has then completed its return movement.
As a means of imparting a positive motion to the operating wheel E, it is preferred
to use a cash drawer K, such as shown in Figure 1, and a rack k on the cash drawer

page_text: may be geared by any suitable intermediate mechanism to the said wheel E. In
Figures 1, 2 and 9, there is shown how the rack k may gear into a pinion on a lower
end of the vertical shaft L in the supporting post of the machine.
This shaft may pass up through one of the legs of the post, as shown in Fig. 2. The
upper end of the vertical shaft as shown in Fig. 2, carries a worm gearing into a
worm wheel on a horizontal hollow shaft h which is mounted to turn on a fixed spindle
on the frame and carries a driving wheel H geared directly or through intermediate
pinions into the operating wheels E of the indicating systems which are grouped
around the driving wheel.
The construction of this driving wheel H will be understood on reference to
Figures 6 and 8 from which it will be seen that instead of being a complete gear
wheel it has two segmental racks or gears g, 9' lying in different planes. They are
preferably so proportioned and so set with reference to each other that a diametrical
line connecting the opposite ends of one segment will lie at right angles to a
diametrical line connecting the opposite ends of the other segment as will be seen on
reference to Figure 6.
One of these segmental racks g is in this instance adapted to gear into the operating
wheels E of the diametrically opposite systems for the pounds and shillings while the
other segmental rack g' is adapted to gear into the operating wheel E of the pence
system.
It will be seen, however, that as the segment is about the length of a semi-circle,
or slightly less, it can gear into only one of the two operating wheels for the pounds
and shillings at any one time, and the driving wheel H with its segmental racks and the
operating wheels E of the several systems are so proportioned that the length of each
rack is about equal to the circumference of each operating wheel E.
It is preferred to combine with this construction safety devices whereby the racks
on the driving wheel shall always gear properly into their operating wheels. For this
purpose something in the nature of a "Geneva stop" is made use of, and con-
sisting of the curved segment e² carried by each wheel E and coinciding with the
smooth part of the circumference of the driving wheel H. This smooth circum-
ference in this instance lies between the planes of the segmental racks g g¹
(Figure 8).
At proper points in this smooth circumference are cut notches which permit
the projecting parts of the segments e² to enter therein and allow the corresponding
operating wheel E to turn as soon as it comes into gear with its corresponding
rack. As soon as the operating wheel has completed its revolution and becomes
disengaged from the rack of the driving wheel, the curved segment will find
itself coinciding with the smooth periphery of the driving wheel, and the operating
wheel will then be locked in the proper position to re-engage with the rack on
the return movement of the driving wheel.
It is to be understood that the term "cash drawer" is used in this description
in a sufficiently comprehensive sense to include not only a construction in which
a sliding, swinging or pivoted drawer itself moves and imparts motion to the
indicator, but also such a construction as where the moving lid or cover of the
cash drawer shall be the means of similarly imparting motion to the indicator.
Instead of employing the drawer to operate the indicator in the manner described,
any other handled device may be used which can be grasped by the operator to
make the indication after the appropriate keys have been operated. For instance
there may be used a handled wheel or lever with a geared segment on it, which
segment gears into a pinion on the upright shaft L, before described.
In Figure 1 there is indicated by dotted lines a wheel W which is provided with a
handle and has on its side a segmental gear engaging with a pinion on the upright
shaft L.
It is preferred to combine with the indicating mechanism above described, some
suitable totalizing or registering mechanism, although it is not desired to be confined
to any special construction of such registering or totalizing mechanism.
As an illustration of one form of such mechanism, there is shown one or more

page_text: registering or totalizing wheels T, T¹, T. in connection with each indicating system.
Three totalizing wheels for the pounds system, for instance, are mounted upon the same
central spindle a as the indicator disk between the indicating disk, its operating wheel
and the tripping disk on one side and the back of the casing or frame on the other
(Figure 5). An opening is formed on the back of the casing through which the
numbers can be read by the saleman (Figs. 2 and 5).
"
There is in this instance attache to the indicating wheel through the medium of the
sleeve d, a pawl-carrying arm R, which has a pawl engaging with suitable ratchet
teeth upon the first totalizing or registering disk T. According to the direction in
which this pawl and the teeth on the wheel T are arranged. the indicator disk may
thus operate the first registering wheel either on its forward or backward movement.
In the present instance the register wheel is shown in Figure 5 as arranged to be operated
on the return movement of the indicator. At each complete revolution of the first
registering wheel a one-space movement is imparted to the second registering wheel T'
by means of a pawl on the first registering wheel entering a recess or notch in the
fixed intermediate disk and engaging with one of the ratchet teeth on the wheel T'
and moving the latter for the space of one tooth, when the pawl again rides out of the
notch on the disc t and out of engagement with the teeth upon the wheel T, until it
completes another revolution.
In a similar way the second totalizing wheel T, at each complete revolution, imparts
a one-space movement to the third registering wheel T, and so on, according to the
number of registering wheels employed. The shillings and pence systems each require
but one registering wheel T.
It will be readily understood that details in the construction of the machine may be
varied without departing from this invention. For instance inste id of mounting the
pawl E on the operating wheel E and its engaging tooth upon the indicator, as
described, the arrangement, may be reversed, that is to say the pawl E may be
mounted upon the indicator D while the engaging tooth is upon the operating
wheel E.
Similarly the pawl M may be mounted on the indicator D and the notch or
tooth m on the wheel E, this pawl and its tooth being in such case reversed from
the position shown in Fig. 4.
An arrangement of registering wheels for the three systems are shown in Fig. 4.
Each of these registering wheels is provided with ratchet teeth corresponding in
number with the figures on the wheels. Into these ratchet teeth engage pawls
on the arms or wheels R' driven by the operating wheels E of the several indi-
cating systems, and these pawls may be so set that the registering wheel of any
one system may be operated on either the forward or return movement of the
operating wheel E.
In Fig. 4 the pawls of the two systems for the pounds and shillings are shown
as set to move their registering wheels when the operating wheels are moved in
one direction, while the pawl of the pence system is shown as arranged to
operate the pence registering wheel when its operating wheel E is moved in the
oiler direction.
Since the rack g of the driving wheel moves the operating wheels E for the pounds
and shillings, in succession on its forward movement, and the remaining wheel E for
the pence system on the return movement, it will be seen that by this arrangement,
one registering wheel only will be moved during the first half of the forward revolu-
tion, and another will be moved during the next half of the forward revolution of the
driving wheel, while the third registering wheel will be moved during a part of the
return movement of the driving wheel. By this means, no two registering wheels are
moved during the same interval of time, and consequently the registering movement
of one wheel may be carried over to the next higher without any possible danger of
mistake such as inight occur if any two of the registering wheels should be operating
at the same time.
Any convenient means for carrying over from one registering wheel to the next
may be used, and in Fig. 4 there are shown devices which may be conveniently

page_text: employed for that purpose. These consist of a pawl rod or bar t' mounted to slide in
guides in the frame and acted on by springs to normally move the bar in a
direction opposite to that indicated by its arrow in Fig. 4. The end of each bar
carries a spring pawl to engage with suitable teeth or depressions in the registering
wheel. A pin or projection on each registering wheel, (except the last) indicated
by dotted lines in Fig. 4, acts on the rear end of the adjacent pawl bar as the
registering wheel completes its revolution, so that each complete revolution of say the
lowest registering wheel will cause a one-step movement to be imparted to the next
higher wheel.
In order to prevent the parts from being returned to zero for a new operation before
the drawer and consequently the driving wheel H have been moved to their full
forward limit, safety devices, such as illustrated in Figs. 7 and 8, are provided. These
consist of a ratchet wheel M fixed to or formed in one with the driving wheel H, or
geared to the driving wheel H so as to move with it and with this ratchet wheel is
combined a pawl N pivoted to the frame or casing. This pawl has a tail piece n'
adapted to be acted on by a pin or projection o on a wheel O which has as many arms
as there are indicating and registering systems. In the present instance, as shown,
this wheel O has four arms, and it is free to turn to a limited extent upon the shaft of
the driving wheel H. These four arms project outward at such points that they will
lie in the paths of pins or projections upon the tripping discs F of the several
indicating systems, one tripping disc F only being indicated in the drawings. Normally
this wheel is in such a position that its pin or projection o, acting on the tail n¹ of
the pawl N, will, against the action of a suitable spring, keep the pawl N4 normally
out of engagement with the ratchet M, but when one of the tripping discs is moved
by the operation of any key of its system, the pin on the tripping disc F will strike
the arm of the wheel and move it in the direction of its arrow, Fig. 7, into the
position indicated in that figure. The pawl N will thus, under the action of its
spring, fall into engagement with the ratchet wheel M and then the driving wheel H,
while it can move forward in the direction of its arrow, cannot be moved backwards
until the pawl N is thrown out of engagement with the ratchet wheel again. This
latter is effected by a pin m² on the ratchet wheel acting (on the completion of the
forward movement of the driving wheel) upon the left hand side of the lever or arm J
(in the figure) so that the latter acting on the pin o of the pawl-controlling wheel O,
will push it from the position shown in Fig. 7, in the direction of the arrow 3.
Through the action of the pin o upon the tail of the pawl N4, the latter will be freed
from the ratchet wheel again and the driving wheel and indicating wheels can then
be returned to their normal or zero positions.
As the extent of movement of the cash drawer K is in most cases more than
sufficient to give the necessary extent of rotary movement to the upright shaft L,
there may be combined with the rack and pinion a safety device somewhat similar in
character and operation to the safety device used on the driving wheel H, as shown
in Fig. 6. It is preferred to have this lost motion between the drawer and pinion
either wholly or partly at the end of the closing movement of the drawer, as shown in
Fig. 10, so that even should the salesman by accident not push the drawer entirely in
for making his change he will nevertheless have. pushed it so far in as to return the
indicating mechanism to zero. The safety device (Figs. 2, 9 and 10) consists of a flat-
sided washer W which runs upon a rib or flange on the drawer or rack as the
pinion becomes disengaged from the rack at either end. In this rib or flange are
formed notches 2 adjacent to the ends of the rack k so that as the pinion enters into
engagement with the rack either on the forward or backward movement of the drawer,
the pinion will be then free to turn until it has completed a revolution while in engage-
ment with the rack; then the flat side of the washer W, as the pinion disengages
from the rack, will come into coincidence with the flange k so as to hold the pinion
in proper position for reengagement of the rack on the return movement of the
drawer.
The general manner of using the cash indicating and registering mechanism
illustrated, will now be briefly described, although the foregoing explanation of the

page_text: construction will no doubt have made this tolerably clear.
In this explanation of the
operation, it will be assumed that a cash drawer is used as the handled device for
imparting a positive motion to the indicator, although, as has been said, it is not
desired to be limited thereto.
Suppose now the cash drawer to be closed and it is desired to make an indication
and registry of a sale of four pounds, eighteen shillings and sixpence (Figure 3), the
salesman pushes inwards the fourth key on the pounds indicator, the eighteenth key
on the shillings indicator and the sixth key on the pence indicator, either all at once
or one after the other. This will not cause any indication to be shewn yet, however,
but will simply put the operating wheels E into engagement with their indicator dises
and at the same time put the ends of the stems of the operated keys into the paths of
the tails of the pawls E' to release the operating wheels from engagement with the
indicators at the moment when the proper numbers come opposite to the openings in
the casing of the machine. The salesman then pulls the drawer out and in doing so,
carries around the wheels E to the full extent of their movement, which is almost, but
not quite, a complete revolution. The indicator wheels being in engagement with the
drawer from the beginning of its movement move with the drawer; but the indicator
wheels stop their revolutions at the positions determined by the keys pressed in, as
already described. The salesman now having put the money in the drawer, and
obtained the change where needed, pushes in again the drawer and in doing so returns
the wheels E to their first or normal positions, and with them he returns the indicators
also, which then show zeros at the openings in the casing. At the same time the
amount of the sale is carried over to the registering mechanism either on the forward
or backward movement of the indicators or both, according to the way in which it
may be constructed, as before stated. If preferred, the forward movement of the
indicator may be made while the drawer is being pushed in, instead of as it is being
pulled out, but that is not considered so desirable.
It will be seen that until and unless a key is pressed in, the moveable indicator is
out of engagement with the drawer and will not be operated although the drawer may
he pushed out or in to any extent, so that normally the drawer is free to be moved in
and out without operating either the indicator or the registering mechanism.

motion to the indicator, and a series of keys numbered to correspond with the latter
and the operation of any one of which throws the said operating device into engage-
ment with the indicator and also disengages them when the indicator has been moved
to the extent determined by the key, all substantially as described.
18. An indicating and registering machine having a series of numbered controlling
keys with a vertical post supporting the said machine with its keys and a shaft to
transmit motion to the indicating and registering mechanism and means to operate the
shaft all substantially as set forth.
19. The combination of two or more indicating mechanisms, each having in a
separate and detachable frame or casing a movable indicator in the form of a disk and
an operating wheel therefor with a frame supporting a common driving wheel to gear
with the several operating wheels and supporting the detachable mechanisms arranged
about the said driving wheel as a centre and a vertical post to support the said
frame.
20. The combination of two or more registering mechanisms each having an
operating wheel, with a common driving wheel having one or more racks to gear
with the operating wheels of the separate registering mechanisms, and operate the
several registering mechanisms in independent intervals of time.
21. The combination of two or more indicating and registering mechanisms each
having a movable indicator and one or more registering wheels & an operating wheel
therefore with a common driving wheel having one or more racks to gear with the
operating wheels of the separate mechanisms and rotate the said operating wheels
first in one direction to make indications and part of the corresponding registries
and then in the reverse direction to return the indicators to zero and make the
remaining registries.
22. The combination of two or more indicating and registering mechanisms, each
having a moveable indicator and one or more registering wheels and an operating
wheel therefor, with a common driving wheel having one or more racks to gear with
the operating wheels of the separate mechanisms and rotate the different registering
wheels independent intervals of time, and carrying devices for transmitting motion
from one registering wheel to the next higher.
23. The combination of two or more indicating and registering mechanisms each
having an operating wheel with a common driving wheel having one or more racks
R

page_text: to turn some of the operating wheels at different times and a safety device, sub-
stantially as described, to lock one or more of the operating wheels while the driving
wheel rotates the others.
24. The combination of two or more indicating mechanisms and a driving wheel
therefor, with a ratchet wheel moving with the said driving wheol, a pawl adapted to
engage with the said ratchet wheel, and means to disengage it at the end of the
movement of the driving wheel in making an indication.
