Improvements in Cash Registers and Indicators.
I, HUGO COOK, of Dayton, Ohio, United States of America, Mechanical
Engineer, 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 :-
Heretofore, in the machines of this character with which I am familiar, the
indicator has always had a reciprocating movement, (either in a straight line, or in
the are of a circle.) being moved in one direction, from zero or normal position, to
make the indication, and then in the opposite direction, back to zero or normal
position, to destroy the indication.
Likewise, the registering wheel, while revolving in one direction only, has been
actuated by a device having a reciprocating movement, the wheel moving with the
actuating device in one direction, but remaining stationary while the actuating
device moved in the opposite direction.
My present invention is believed to involve a radically new mode of operation
in this class of machines; first, by reason of the fact that the indicator does not
have a reciprocating movement, but revolves in one direction, both to make the
indication, and to destroy it preparatory to the next indication; and, second, by
reason of the fact that the driver or actuating device for both the indicator and
register is also revoluble and has no reciprocating movement.
My invention contemplates the employment of the revoluble indicator and
revoluble driver, without the register; and, likewise, the revoluble register and
revoluble driver, without the indicator; as well as the employment of both the
indicator and register with the driver.
The driver has a uniform stroke or limit of movement, (preferably one complete
revolution,) at each operation of the machine, while the movements of the indicator
and register vary according to the amount to be indicated and registered.
A. suitable latch, or other connecting and disconnecting device, is employed to
connect the driver with and permit it to be disconnected from the indicator and
register. Where both an indicator and register are employed in the machine a
single latch may be made to co-operate with both the indicator and register. In
its co-operation with the register the latch is controlled and operated by a fixed
stop or stops, and a movable stop or series of stops, either to cause the driver and
register to be connected at a fixed point and disconnected at different points, or
to be connected at different points and disconnected at a fixed point, as hereinafter
explained. In its co-operation with the indicator the latch may, or may not, be
operated by both the fixed stop and the movable stops, depending upon the con-
struction and arrangements of parts employed, for in some instances, as will be
explained, the fixed stop or stops may be dispensed with, so far as the co-operation
of the latch with the indicator is concerned, and the latch be arranged to connect
the driver and indicator, independently of any stops, and the movable stop or stops
be alone employed, to disconnect them.
Since the indicator and register are both revoluble, the primary device with
which the latch connects the driver and to which the latter transmits power, is
also revoluble; in the machines illustrated in the drawings it is a wheel, inounted
upon the same shaft as the revoluble driver. Such wheel may be itself the
indicator or register, or be simply the driving gear or wheel for an indicator
and register.
In the simplest form of my invention the driver is connected by the latch directly
with a wheel which is itself the indicator, and also with a wheel which is itself the
primary registering wheel, and I have so illustrated the invention in the drawings:

page_text: but in the full development of my invention, in complete machines for the market,
it will often be desirable to employ the primary revoluble part or wheel, with
which the driver is connected by the latch, simply as the actuator for the indicator
or register, which may geared or connected with it, directly or indirectly, in any
suitable manner.
I have devised several different forms of apparatus, all embodying the new mode
of operation, and I have no doubt that I will be able to devise many other forms,
and that others will be able to do so when the mode of operation is explained to
them by the following description of the invention.
of
Inasmuch as my invention is believed to be radically new in principle and mode
operation, it is not restricted, in its broader scope, to any particular construction
or arrangement of apparatus, but contemplates all forms of apparatus involving the
new mode of operation, however widely they may differ in construction.
In the accompanying drawings I have illustrated only a few of the different
forms of apparatus which I have already devised, having selected those which I
believe will best facilitate an explanation of the invention.
Figure I is a side elevation, with the casing in central section, of one form of
cash register and indicator embodying my invention;
Figure 2 is a plan view of a horizontal section on the line 2-2 of Figure 1, with
a section of the top of the casing remaining, to show the reading opening;
Figures 3, 4 and 5, horizontal sectional views of different constructions, showing
various modifications of my invention to be hereafter described in detail.
Figure 6 a side elevation of another construction of machine embodying my.
invention, with the casing in central section as in Figure 1 and
Figure 7 a horizontal section of the same on the line 7-7 of Figure 6.
The same letters of reference are used to indicate identical parts in all
the figures.
In the construction shown in Figures 1 and 2, A is a revoluble shaft journaled
in the top and bottom of the casing B and having secured to it a handle C. Fast
upon this shaft within the casing is a disk D, a top plan view of which is shown in
dotted lines in Figure 2. This disk turns with the shaft A. and handle C and
constitutes what I term the driver. Its two halves are of unequal diameters, so
that shoulders D1 D2 are formed on its opposite sides, both facing in the same
direction. The shoulder D' serves no purpose, but the shoulder D2 forms au
operative part of the driver, as will be hereafter explained. At the base of the
shoulder D² a notch D³ is cut in the periphery of the disk.,
Next above the driver D, Figure 1, is a bar E extending diametrically across
the machine and having its opposite ends E' and E2 beveled on substantially
parallel lines. This bar is mounted at its middle on the shaft A. by an elongated
slot, through which the shaft passes, which slot admits of a longitudinal recipro-
cating movement of the bar, as well as its revoluble movement on the shaft A.
Upon the under side of the bar E, at diametrically opposite sides of the disk D, are
two lugs F and F which co-operate with the shoulder D² and notch D³ in the
disk D, in the manner to be described. Also formed or secured upon the under
side of the bar E near its opposite ends are two beveled or inclined lugs or
canis G, G', the planes of whose operating faces intersect the planes of the beveled
ends of the bar. These lugs co-operate with a fixed pin or cam H, projecting
upward from the bottom of the casing, Figure 1. The beveled ends of the bar E
co-operate with a series of movable stops, cams or keys, H', mounted in the top of
the casing. These keys are not shown in Figure 1, since in that view the near
half of the casing, in which they are mounted, is removed, but their position is
shown in the plan view in Figure 2. They are mounted in guides and arranged to
be pushed in and moved out in the usual manner. When in their outer position
their lower ends are above the horizontal plane of the bar E, but when any on.
of them is pushed in its lower end projects through such plane, as will be readily
understood.
Next above the bar E, Figure 1. is a large wheel I, loosely mounted on the

page_text: shaft A, and constituting, under the construction shown in Figures 1 and 2, the
indicator. It has two series of indicating numbers arranged near its periphery,
each series occupying one third of the circle in which they are located.
Next above the wheel I, Figure 1, and separated from it in this instance by a
collar on the shaft A, is a notched wheel J, which constitutes the registering
wheel or driving gear therefor. Upon the upper side of the bar E are two lugs K
and K which project up through slots in the wheel I, on opposite sides of the

wheel J and co-operate with the notches in the latter.
that while the bar E is free to reciprocate diametrically of the wheel 1, the two
revolve together.
A reading opening in the top of the casing permits the exposure of the
indicating numbers on the wheel I.
The keys H', beginning with the one on the right in Figure 2, represent
successively 1, 2, 3, &c., up to 9. In the position of the parts shown in Figure 2
the beveled end E of the bar E is arrested at the second key, and the number 2
on the wheel I is exposed at the reading opening L in indication of the last
operation of the machine.
A full operation of the machine consists in pushing in one of the keys H', so
that its lower end intersects the plane of the bar E, and then giving the handle C
one complete revolution. The action of the various parts under this operation will
be as follows:
As the driver D moves forward with the handle 'C and shaft A its shoulder D²
will engage the lug F on the under side of the bar E, and will pick up the bar
When
and wheel I, (which moves with the bar,) and carry them forward with it.
the driver D has made one half of a revolution and the shoulder D' has been
brought to a position diametrically opposite that in which it is shown in
Figure 2, the zero on the wheel 'I at a will have been brought under the reading
opening and will stand exposed to view. At this point the inclined lug G,
upon the under side of the bar E, (at the upper left hand end of the bar in
the position of the parts shown in Figure 2,) will ride over the outer side of the
fixed pin at the right hand side of the machine and force the bar E to the right.
This will draw the lug F into the notch D3 at the base of the shoulder D, and
will also draw the lug K into one of the notches in the wheel J and thereby
lock the driver and wheel L to the wheel J. From this point forward all three
will move together, until the end E of the bar E strikes the lower end of the
key which has been pushed in, whereupon, as the beveled end of the bar rides
over the key the bar will be forced toward the opposite side of the machine far
enough to carry the lug out of the notch D in the driver and beyond the
shoulder D thereof, and also to carry the lug K' out of the notch in the
wheel, so that the driver is disengaged from everything and moves on to
norinal position alone, while the bar Ď and registering and indicator wheel come
to rest, with the number on the latter which corresponds to the operated key
exposed at the reading opening.
It will be noticed that the lugs F and F fit closely against the periphery of
the driver, so that the bar E is held from any reciprocating movement when
one of said lugs is in or opposite the notch D³ at the base of the shoulder D².
It results from this that when the end of the bar strikes the key which has been
pressed in and is thereby forced toward the opposite side of the machine, the
lug F on the end of the bar adjacent to the key is moved up against the near
edge of the driver D, into the position of the lug F in Figure 2. The lug F
reaches this position just before the beveled end of the bar quite clears the key,
and as the engagement of the lug with the periphery of the driver prevents any
further movement of the bar in the direction which its contact with the key has
forced it, the bar is positively arrested by the key.
At the next operation of the machine, when the shoulder D³ of the driver
engages the lug the bar is free to move forward because the notch D³ is brought
opposite the lug at the same instant that the shoulder engages it, so that as the
.

page_text: driver bears against the bar to carry it forward the lug can enter the notch far
enough to permit the end of the bar to clear the key. This would be the operation
if the keys were successively operated or allowed to remain in. In machines
of this character, however, the keys are generally so combined with re-setting
springs and detent plates or catches that when one key is pressed in any other
key which has been previously pressed in and detained will be released and thrown
out to normal position. If, therefore, a different key is pressed in at the next
operation of the machine, the one already in the 2 key, for instance-will be
released and thrown outward, so that, so far as this key is concerned, the bar E
would be perfectly free to move forward when the shoulder D² engages its lug,
even in the absence of the notch D³; but if the newly operated key should happen
to be one of higher value than the one last operated it would stand in the path
of the bar E and the latter would become locked upon it, but for the notch D³,
which will permit the bar E to be moved away from the newly operated key as its
end rides over the key.
While it is more convenient to have a separate key H' for each amount to be
indicated and registered, it will be understood that the general mode of operation of
the machine would be the same if there were simply nine holes and a single movable
pin, which could be inserted in one hole or another as desired. Such a pin might
be carried on the outer end of an arm hung to the shaft A and arranged to swing
back and forth over the row of holes; as will be readily understood.
In the construction thus far described the sole purpose of the lugs K and K',
stationary pin H, and beveled lugs G and G¹, is to co-operate with the notched
wheel J, so that in the absence of such wheel all those parts might be dispensed
with. So far as the operation of the indicator wheel is concerned, the only parts
necessary are the driver, the bar D provided with the lugs F and F¹ (or equivalents
therefor), and the bar H¹.
From the construction thus far described it will be seen that the main purpose
of making the driver D in the form of a disk is to lock the bar E from reci-
procating movement except when permitted by the notch D3; and that the
principal operative part of the driver is simply the shoulder D. In Figure 3,
therefore, have illustrated a driver M consisting simply of an arm fast upon the
shaft A and combined with the bar E and keys H', these being the only parts
necessary to the operation of an indicator. Under this construction, when the
driver moves forward its outer end will engage the lug F¹ and pick up the bar E
and carry it on around with it until the beveled end E of the bar strikes the key
which has been pushed in, whereupon the bar will be forced toward the opposite
side of the machine and the lug F¹ be carried outward beyond the end of the
driver M, thereby disconnecting the driver from the bar, the latter coming to rest
at the point determined by the operated key and the driver going on to normal
position.
In Figure 3 I have not shown either an indicator wheel or a registering wheel,
but have shown how the bar E may itself be made to constitute the indicator. As
there shown it is provided upon its upper side near each end with a pointer N
arranged to travel over the periphery of a fixed plate or dial O provided with a
series of indicating numbers. In the drawing the end E2 of the bar E is shown
arrested on the second key and the pointer N at the opposite end of the bar stands
over the figure 2 on the dial. At the next operation of the machine, if the five key be
pressed in the end E¹ of the bar E will be caught on the fifth key and the pointer N
on the end E2 of the bar will come to rest over the figure 5 on the dial, as will be
readily understood.
If desired, a second series of numbers might be placed on the plate O diametrically
opposite those shown, so that the pointers N N would simultaneously point to the
corresponding figures in the two opposite series of numbers.
In Figure 4 I have shown a driver similar in form to that in Figure 3, combined
with the bar E and registering wheel J. Instead of an indicator wheel such as I,
or a fixed dial such as O, I have here shown simply a gear wheel P, from which

page_text: may be driven an indicator of any suitable form and arrangement. Under this
construction, when the driver M moves forward its outer end engages the lug Flon
the bar E and picks up the bar and carries it and the gear Pon around with it,
the wheel J remaining stationary. Just as the driver completes one half of its revo-
lution and reaches a position diametrically opposite that shown in Figure 4, and
the indicator driven by the gear P has been brought to zero, the beveled lug G on
the under side of the bar E rides over the outer side of the fixed pin H and forces the
bar E to the right and thereby draws the lug into one of the notches in the
wheel. From this point forward the registering wheel is carried with the bar E
and driver, until the beveled end E¹ of the bar E engages the operated key,
whereupon the bar E is forced toward the opposite side of the machine and the
lug F carried beyond the end of the driver and the lug K¹ moved out of the notch
in the wheel, so that the bar and wheels P and J come to rest, while the driver is
released and moves on to normal position alone.
In building machines for the market I prefer to connect the gear P by a suitable
speed-increasing train of gears with an indicator wheel provided with only one
series of numbers, so that the figures may be made larger than where two series of
numbers are employed.
In Figure 5 I have shown still another construction, in which the indicator wheel
is operated in a similar manner to that in Figures 1 and 4. The driver consists of
an arm Qfast on the shaft A. The indicator wheel R is loosely mounted on this
shaft. A bar S, provided at its middle with an elongated slot through which the
shaft A passes, is capable of reciprocating diametrically of the indicator wheel, but
turns with it, as does the bar E in Figures 1 and 4. Upon the upper face of the
bar S are two lugs T and T which co-operate with the end of the driver Q. At
the opposite ends of the bar S are two lugs U and U' having beveled inner faces
to co-operate with the lower ends of the keys H³.
The operation of the parts is as follows: As shown in the drawings the lug U1
at the right hand end of the bar is caught on the fifth key and the figure 5 on
the wheel S is exposed at the reading opening, indicated by the dotted lines at d.
As the driver Q moves forward from the position shown in the drawings its outer
end engages the lug T on the bar S and picks up said bar and the wheel R and
carries them around with it, the lug U at the opposite of the bar slipping
over the key upon which it had been caught. When the driver completes one
half of a revolution and reaches a position diametrically opposite that occupied by
it in Figure 7, the zero on the wheel R at c will have been brought under the
reading opening at d. As the driver moves on, in the second half of its revolution,
the figures following the zero on the wheel R will pass successively under the
reading opening, until the lug U on the bar S engages the lower end of the key
which has been pressed in. As this lug rides over the outer side of the key the
bar S will be forced to the right and the lug T with which the driver Q has been
engaged will be carried outward beyond the end of the driver, which, being thus
freed from the bar S and wheel R, will move on to normal position alone, while
the bar and wheel will be arrested at the operated key, with the number on the
wheel which corresponds to such key exposed at the reading opening.
It will be understood that the zero, both upon the indicator wheels and upon
the fixed dial, simply indicate initial positions of the indicator, from which the
forward movement to the new indication begins, so that where I speak of the
indicator being turned to zero I simply mean that it is moved to initial position.
It is not necessary that any zero should be actually placed upon the indicator
wheel or dial.
In Figures 6 and 7 I have illustrated a different embodiment of my invention,
in which the revoluble driver and indicator wheel are connected at different points
by means of the different stops or keys, and are disconnected at a fixed point. In
the construction there shown the general shape of the machine is the same as in
Figures 1 to 5, and the central revoluble shaft A and handle C are employed.
Loosely mounted upon the shaft A is the indicator wheel V. Fast upon the

page_text: under side of the wheel V is a toothed wheel W, while loose upon the shaft A
beneath the wheel W, separated from it in this instance by a spacing disk, is a
similar notched wheel X, whose notches coincide with those in the wheel W.
Fast upon the shaft A beneath the wheel X is a radially extending arm Y,
which carries upon its upper side, in a suitable guideway, a radially sliding latch-
bar or plate Z and constitutes the driver of the machine in this instance.
Upon the upper side of the latch-plate Z, near its middle, is a lug or projection A¹
which co-operates with two lugs B C secured upon the under side of the indicator
wheel V, and upon the upper side of the plate Z at its outer end is a cam lug D¹
which co-operates with a fixed cam or pin E', depending from the under side of the
top of the casing as seen in Figure 3. The outer end of the latch-plate Z is beveled
off and co-operates with a pin F1 diametrically opposite the pin E', and with the
series of movable stops or keys H'. At its inner end the plate Z is provided with
an upwardly projecting lug or tooth G', which co-operates with both of the wheels W
and X all in the manner hereafter explained.
In the construction shown in Figures 6 and 7 nineteen keys are shown, and the
indicator wheel is provided with two series of nineteen numbers, each representing
multiples of five from 5 to 95, with a zero between the 95 and 5.
As in the construction shown in Figures 1 to 5, so in the construction shown in
Figures 6 and 7, a full operation of the machine consists in pressing in a key and
turning the operating handle one complete revolution. This will register the value
of the key and leave a number upon the wheel V corresponding to such value
exposed at the reading opening at J.
In the position of the parts shown in Figure 7 the operating handle and driver
are at rest, the latch plate Z has been slid to its outermost position and its tooth G¹
withdrawn from engagement with the wheels W X by the cam lug D₁ riding over
the fixed cam E. The number 25 is exposed at the reading opening in indication
of the preceding sale. It will be seen that the lug B on the indicator wheel V
lies directly in the path of travel of the lug A' on the latch-plate Z when the latter
is in its outer position, as shown in Figure 7. The result of this is, that when the
driver Y is revolved by turning the handle C and shaft A the lug A will engage
Just as the
the lug B and pick up the wheel V and carry it around with the driver.
driver completes the first half of its revolution and brings one of the zeros on the
indicator wheel beneath the reading opening, the outer beveled end of the latch-
plate Z strikes the stationary cam or pin F and is driven slightly inward-far
enough to carry its lug A¹ out of the line with the lug B', with which it has been
engaged, to thereby disconnect the driver from the indicator wheel V, but not far
enough to engage the tooth G with the wheels W and X. As the driver is turned
on, in the second half of its revolution, the wheel V remains stationary, with the
zero, exposed at the reading opening, until the outer end of the plate %, which is
travelling beneath the row of keys H', strikes the key which has been pressed in,
whereupon said plate is slid still further inward and its tooth G¹ enters two
co-incident notches in the wheels W X. From that point on until it completes its
revolution the driver carries with it both of the wheels W X, and also the indicator
wheel V which is fast to the wheel W. As the driver completes its revolution the
cam lug D on the plate Z rides over the stationary pins E, the plate is slid to the
left, into its outermost position, withdrawing its tooth G' from the wheels W and X,
whereupon the latter come to rest, with a number upon the wheel V corresponding
to the value of the operated key exposed at the reading opening. Thus, when the
driver is connected with the wheels at any given key it will turn them just far
enough, before it is disconnected from them at the pin E', to expose at the reading
opening a number corresponding to the value of the operated key and to add such
value upon the registering wheel. The outward movement of the plate Z at the
pin E, again brings the lug A' into line with the lugs B and C on the indicator
wheel, ready to pick up the latter and carry it around to zero at the next operation
of the machine.
The wheel X in this case will be the registering wheel, or the driver for a train

page_text: of registering wheels, as desired. It will be understood from the above description
that the tooth G' of the latch-plate Z engages the wheel X simultaneously with the
wheel W, and that the tooth is disengaged from both wheels at the sime time.
The wheel thus turns with the wheels W and V while the latter are moving
forward from zero, to make the new indication, but remains stationary while the.
indicator wheel is being turned to zero during the first half of the revolution of the
driver.
As in the construction before described, (Figures 1 to 5) any suitable device may
be employed for temporarily holding the operated key in its inward position and
for releasing it and restoring it to normal position when another key is pressed in.
Likewise, both in this and the before described constructions, any suitable devices
may be employed to arrest the operating handle and driver when they complete a
revolution and arrive at normal position; but such devices are so common in this.
class of machines that it is unnecessary to illustrate or describe them.
In the construction shown in Figures 6 and 7 it will be understood that the sole
purpose of the lug A' on the latch-plate Z, the lugs B₁ C² on the indicator wheel V,.
and the fixed cam F¹, is to cause the driver to turn the indicator to zero during its.
first half of its revolution, and to leave it there until again connected with it by the
operated key. In the absence of the indicator wheel, therefore, these parts might
be dispensed with, the only elements essential to the operation of the register being
the driver Y, latch-plate Z having the arm D', the fixed pin E', keys H', and
wheel X. Under the operation of these last named parts the driver would move:
forward from normal position alone until the outer end of the plate Z engaged the
operated key, whereupon the driver would become locked to the wheel and turn
it on with it until disconnected from it by the engagement of the lug D' with the
pin E.
From the foregoing description it will be seen that the foundation of my invention,
consists in a driving device which revolves in one direction only, combined with.
another independently revoluble part which also revolves in one direction only, and
means for connecting the two, to cause the driver to carry the other part with it,
and means for disconnecting them, to cause the driver to release the other part and
move on alone, the result being that while the driver is given a uniform movement.
at each operation of the machine, the other revoluble part will be moved by it a
greater or less distance, depending upon the points of connection and disconnection.
of the two.
It will also be seen that the revoluble part to which I refer may be either a
registering wheel or wheel for driving a register; an indicator, or wheel for driving-
an indicator or it may not be a wheel at all, but simply a device for connecting
the driver to the indicator or registering wheel, or for transmitting the movements.
of the driver to some other movable part, or it may itself constitute the indicator..
