Improvements in Cash Registers and Indicators.
I, HUGO COOK, of Dayton, Ohio, United States of America, Manufacturer,
do hereby declare the nature of this invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
My present invention may be said to be in some respects an improvement upon
that for which Letters Patents No. 9370 dated June 10, 1890 were granted me,
and in others to be a new and independent invention. In both my present machine
and that shown in my prior Patent, the registering wheel is driven by a spring
impelled motor which is normally held in check by an escapement mechanism
under the control of the operating keys of the machine, in such manner that when
a key of given value is operated, the escapement mechanism which holds the motor
in check is caused to release it and permit it to turn the registering wheel a given
distance and to then arrest it again.
Upon operating a key of different value the motor is released and rearrested
after having turned the registering wheel a different distance, the adjustment of
the parts in both cases being such that at each operation of a key the motor is
permitted to turn the registering wheel just far enough to register the value of the
operated key.
In both machines the escapement mechanism consists of a series of detents
(so called merely because they serve to detain a movable part) and a series of
escapements co-operating therewith.
In both machines the detents are shown as supported upon wheels or disks
though the particular form of their support is immaterial and the escapements
are shown in the form of toothed wheels mounted upon the same axis as the detent
supports.
In my first machine, (the one shown in my prior Patent) the detent supports
were under the direct influence of the motor and were held in check by the
relatively non-revoluble escapement wheels, so that when an escapement wheel
was moved toward and from its co-operating detent to disengage one of its teeth
therefrom, the detent and its support revolved until arrested by the next
succeeding tooth of the escapement wheel, while the latter remained relatively
stationary.
In my present machine, the escapement wheel not only moves laterally towards
and from its co-operating detent, but also revolves when one of its teeth is disengaged
from the detent, while the latter remains relatively stationary.
Between the specific forms of escapement mechanisms illustrated in my prior
Patent and in my present application, there is therefore this difference, namely,
in the former, the revoluble detent co-operates with a relatively non-revoluble
escapement wheel, while in the latter a revoluble escapement wheel co-operates with
a relatively non-revoluble detent.
This specific difference will be pointed out in some of the claims of my present
application but in its broader scope neither my former nor my present invention is
restricted to the specific form of escapement mechanism illustrated.
Where the escapements are in the form of wheels and the detents are mounted
on the same axis either the detent or the escapement may be the part which moves
laterally and revolves relatively to the other.
In my first machine, the escapements and detents were mounted upon a fixed non-
revoluble shaft; while in my present machine they were mounted upon a revoluble
shaft. Improved results flow from the employment of the revoluble instead of the
fixed shaft and it forms one of the principal lines of distinction between my present
and former machines.

page_text: These, as well as the various other features of my present invention will be
hereinafter fully described and specifically set forth in the claims.

Similar letters of reference in the several figures indicate the same parts.
In the drawings the letter A represents the main frame of the machine constructed
preferably of metal and of sufficient strength and rigidity to properly support the
various operative parts.
Extending from side to side of this frame is what may be termed a motor shaft B,
the same being supported by the end plates of the frame and also by two
brackets C C¹ secured to a cross bar D as shown in Figure 1 so as to permit
said shaft to turn freely.
Upon one end of this shaft B is secured a ratchet wheel B', Figure 3 with
which is adapted to engage a spring pressed pawl B2 pivoted to the upper arm of
the lever B3 mounted loosely upon said shaft. The lower arm of the lever B³ is
slotted at B and into this slot projects a stud or screw B³ carried by a slide or
traveller B that is adapted to move back and forth upon a guide rod or way B'.
When the lower end of the lever B³ guided by the slide B is pushed toward
the rear of the machine, the said lever is caused to swing upon the shaft B and the
pawl B2 carried by its upper arm causes the ratchet wheel B and with it the
shaft B to be turned in the direction indicated by the arrow in Fig. 3 but as soon
as the lever B³ is released, a spring, B connected at one end to the upper end
of the lever, and at the other end to a fixed part of the frame swings the lever
in the opposite direction and in position to impart through its pawl another
impulse to the shaft B when again operated.
Mounted loosely on the shaft B near the middle thereof, Figs. 1 and 17, is a
friction drum E containing a helical spring E', the outer end of which is connected
to a split ring E2 that bears with frictional contact against the inner circumference
of the drum, and the inner end of which is connected to a sleeve E³ fixed to
and rotating with the shaft B and having a ratchet wheel E* secured to it
outside of the drum as shown in Fig. 1. A pawl E' pivoted to the bracket C is
!

page_text: provided for engaging said ratchet wheel. When the shaft B, the sleeve E³ fixed
to it winds up the spring E' and the latter, through the friction ring E' tends
to rotate the drum in the direction indicated by the arrow in Fig. 1. Secured to
or formed upon the drum E is a gear wheel E which meshes with a pinion F
secured to a revoluble shaft G that has its bearings at one end in the upper arm of
the bracket C and at the other end in the side plate of the frame, as shown in
Figs. 1, 2 and 7.
Mounted fast upon the shaft G near its right end is a registering wheel H, whose
periphery is divided into twenty equal parts numbered from 0 to 95 respectively.
This registering wheel is provided with a hub or fixed sleeve H¹ Fig. 7 upon which
is mounted the hub J of what I term an escapement wheel or detent arrester J
a spline and groove connection being provided between the two so as to cause both
to turn together and yet enable the escapement wheel to be moved laterally
independently of the registering wheel.
Mounted loosely upon the shaft G adjacent the escapement wheel J is what I
term a detent wheel or support K the same consisting of a disc provided with an
elongated hub K' and carrying a detent L which is adapted to engage with one or
the other of the teeth of the escapement wheel .J.
Upon the hub of this detent wheel K is secured, by a spline and groove
connection another escapement wheel J' which is adapted to co-operate, in turning,
with another detent wheel K and following in order along the shaft are other
escapement wheels J³, J and J' and detent wheels K and K' co-operating with
said escapement wheels J³ and J. The escapement wheel J' instead of co-operating
with a detent L on a revoluble detent wheel, as to all the other escapement wheels
in the series, co-operates with a fixed detent L' secured to the bracket C as shown
in Figs. 27 and 8.
The spring drum E tends to rotate the shaft G, the registering wheel H secured
to it, and the connected series of escapement wheels J, J, J3, J, J and detent
wheels K, K, K³, K', in the direction indicated by the arrow on the wheel H, and
would so rotate said parts were it not for the fact that the stationary detent L' holds
them in check.
By referring to Fig. 22 it will be seen that each of the detents L is provided
with two contacting or engaging faces, that is to say, an outer face and an inner
face . It is with the outer face that the tooth of each escapement wheel is
normally engaged, but whenever said wheel is moved laterally toward the face of its
co-operating detent wheel its tooth which happens at the time to be engaged passes
out of the plane in which said outer face is located and into the plane into which
stands the inner face I' and under the influence of the spring drum, said escapement
wheel is advanced till its next succeeding tooth comes in contact with the said inner
face after which upon the outward or return movement of said escapement wheel
the said second tooth, which has so engaged said inner face slips out of the plane
in which said face is located and back into the plane of the outer face thus
permitting the escapement wheel to again advance till said second tooth comes in
contact with said outer face l.
From this description it will be seen that, in order to advance an escapement
wheel a distance equal to the space between any two of its teeth, the said escapement
wheel must be first moved laterally toward and then away from the co-operating
detent wheel upon which the detent is mounted.
Each of the escapement wheels is assigned a particular value determined by the
number of peripheral teeth with which it is provided. For instance, the escapement
wheel J is called the five cent wheel because it is provided with twenty equidistant
teeth and its operation is designed to effect the advance of the shaft G by twentieths
of a revolution, each of which represents the twentieth of a dollar, or five cents, as
shown by the registering wheel K and a complete revolution of said shaft represent-
ing one dollar. In like manner the wheel J is called the ten cent wheel because it
has ten teeth; the wheel J³ the twenty cent wheel because it has five teeth; the

page_text: wheel J' the second twenty cent wheel because it also has five teeth and the wheel J
the fifty cent wheel because it has but two teeth.
If it should be desired to register five cents upon the registering wheel it would
only be necessary to move the escapement wheel J laterally so as to move its
engaged tooth out of contact with the outer face of its co-operating stationary
detent L' and into the plane of the inner contacting face whereupon, under the
propelling action of the spring drum, as transmitted through the whole series of
escapement wheels and detent wheels and the shaft G as before described, the said
escapement wheel J will be advanced till its next or second tooth comes in contact
with the said inner face l' of the detent L' and then, upon a reverse or return lateral
motion of said escapement wheel said second tooth will be brought back again into
the plane of the outer contacting face and by a further advance its said second
tooth will be brought up into contact with said outer face thus effecting a com-
plete movement of the escapement wheel J³, or in other words causing its advance
a distance equal to the whole width of the space between two of its teeth.
In like manner when it is desired to register ten cents, twenty cents, etc. the
appropriate escapement wheel is moved laterally, toward and from its co-operating
detent wheel and said escapement wheel advances the distance between its two
teeth, all the connected escapement wheels and detent wheels of higher denomination
advancing with it, the escapement wheels of lower denominations only, not being
affected.
The registering wheel H as we have seen is adapted only to indicate the register-
ing of amounts of five cents and multiples thereof up to ninety five cents, and
further provision of mechanism is therefore required in order that sums of one dollar
and multiples thereof may be registered, as well as that the complete revolution of
the cent registering wheel H, each of which of course represents a dollar, may also
be registered.
Such additional mechanism is shown in the accompanying drawings and is
constructed as follows.
یر
At the front of the machine and in line with the shaft G, Figs. 1, 2, 7 and 8 is
another revoluble shaft M which is a substantial counterpart of the shaft G and has
its bearings at one end in the side plate of the frame and near the other end in the
bracket C. Upon this shaft M is fixed a disc N having an elongated hub N' and
upon this hub and connected to it by a spline and groove connection is an escape-
ment wheel N with which is adapted to co-operate an adjacent detent wheel O.
Following along the shaft toward the middle of the machine are other escapement
wheels N³, N, N3, No, and their co-operating detent wheels 01, 03, 03, 04, the last
named detent wheel O being rigidly connected to an additional escapement
wheel N which is adapted to engage with a detent P mounted on a sliding rod Q
supported in bearings in the brackets C' C.
The disc N in this series being fixed to the shaft M bears the same relation to
the said shaft and to its associated escapement wheels and detent wheels, as does
the registering wheel H to its corresponding associated parts on the cent registering
mechanism, and the shaft M is kept under tension by means of a second spring
drum Qmounted upon and formed from the shaft B and geared to the shaft M by
means of a gear Q and pinion Q2 all as shown in Figs. 1 and 2.
Also mounted upon and secured to the shaft M is a gear wheel M' which meshes
with the first of a train of registering wheels 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 as
shown.
The detent P while mounted upon a sliding rod, for a purpose hereinafter
described, is, so far as its co-operation with the train of wheels N, O, N³ 01 etc.
practically a stationary detent, and holds said train in check, against the impulse of
the motor, just as the stationary detent L' holds in check the train on the cent side
of the machine. Inasmuch as the last escapement wheel N' and the last detent
wheel O' are rigidly secured together and are loose on the shaft M and are held
stationary at all times except during when a transfer from the cent wheel is being

page_text: made in the manner hereinafter described, it follows that the detent on the wheel O₁,
engaging the teeth of the escapement wheel N is really the end of the train of
escapement mechanism on the shaft M and in this respect corresponds to the
stationary detent L' on the cent side of the machine. The operations of the shaft M
and the wheels mounted thereon in effecting the registry of dollars on the dollar
registering wheel, would be the same if the escapement wheel N and detent
wheel Owere omitted and the detent on the latter were mounted upon the-
framework, as is the detent L'.
The escapement wheel N has twenty teeth and is adapted, when released from
its co-operating detent wheel, to permit the shaft M to rotate sufficiently to register
one dollar on the train of registering wheels 1, &c. while the escapement
wheels N N N N have ten, five, four, and two teeth respectively and are
adapted when operated to respectively cause 2$, 48, 5$ and 10$ to be registered on
said registering train.
The manner in which these escapement wheels of the dollar registering
mechanism are shifted laterally to and from the detent wheels is precisely the
same as hereinbefore described in detailing the operation of the cent registering
mechanism and does not therefore require further description.
The registering upon the dollar registering mechanism of the number of complete
revolutions of the cents registering wheel and shaft, or in other words, the transfer
to and registration upon the dollar registering mechanism of every dollar registered
upon the cent registering mechanism, is effected in the following manner and by
the following instrumentalities.
Upon the inner end of the shaft G of the cent registering mechanism is rigidly
secured a sleeve or collar S provided with right and left spiral grooves S', S², in
which works the edge of a head or piece S³ that is mounted so as to turn freely on
its longitudinal axis in a socket S₁ secured rigidly to the sliding rod Q3 that
carries at its end the detent P with which the additional escapement wheel N'
co-operates.
Each time the shaft G of the cent registering mechanism makes a complete
revolution, the head or piece S³ is carried by one of the spiral grooves from right
to left, thus moving the sliding rod Q until the outer contact face p of the detent P
is moved out of the path of the tooth of the escapement wheel N' with which it has
been engaged and the inner contact face p' of said detent is brought into the path
of the next succeeding tooth of the said escapement wheel as shown in Fig. 8 thereby
releasing one tooth of said escapement wheel from the first named contact face and
catching the next succeeding tooth on said last named contact face and permitting
an advance of the escapement wheel, and of the shaft M of the dollar registering
mechanism to which it is indirectly connected by means of the intervening detent
wheels and escapement wheels a distance equal to half the distance between two of
the teeth of said escapement wheel N and upon the next revolution of the cent
registering shaft G the other spiral groove will cause the head piece S³ to be
shifted from left to right and thereby move the detent P so that its inner face p¹
now engaged with the second tooth of the escapement wheel N7 will be withdrawn
out of the path of said tooth and the latter will move forward against the outer
contact face p which has meanwhile been brought in its path, thus causing the
further advance of the dollar registering mechanism.
The escapement wheel N has but ten teeth but inasmuch as it is advanced but
half the distance between any two of its teeth at a time, the effect is the same as
though it were provided with twenty teeth and operated like the escapement
wheel Nº.
As above described, the escapement wheel N is connected with the gear Q' of
the second motor indirectly through the shaft M and the train of wheels mounted
thereon but it will be clear from the above description that such indirect connection
of it to the motor is merely incidental to the employment of the shaft M and the
dollar train of wheels mounted thereon. The essential fact, so far as the transfer
mechanism is concerned, is that the escapement wheel is connected with the motor

page_text: which actuates the dollar wheel so that when released by the detent P it will permit
the motor to turn the dollar registering wheel far enough to register one dollar
thereon. The essential parts of this transfer mechanism are, therefore, the motor
for driving the dollar wheel, the escapement wheel connected with it and the detent
which releases and arrests the escapement wheel at proper intervals in the move-
ments of the cent registering wheel to permit the motor to actuate the dollar
registering wheel.
.
As before stated the total register is geared to the dollar shaft M by the
gear M. The gears, 1, 3, 4, 6, 7, 9, 10 of this total register are all mounted
loosely upon a common shaft T secured in fixed arms TT, Figs. 1, 9 and 10
while the gears 25 and 8 and 11 of said register are mounted loosely upon a
shaft T secured in a swinging frame T3 hung upon a shaft T and adapted to be
held in adjusted position by means of a screw T or other equivalent adjusting
device as shown in Figs. 9 and 10. When the outer end of said frame T³ is lowered
by manipulating the screw T or other adjusting device the gears 2, 5, 8, 11 carried
by said frame are thrown out of mesh with gears 1, 3, 4, 6, 7, 9, 10 so as to enable
said first mentioned gears to be independently revolved and set while at the same
time a cross bar T at the rear of said frame rises into engagement with the teeth
of the gears 1, 3, 4, 6, 7, 9, 10 as shown in Fig. 10 and locks said gears from
further rotation in either direction. The upward motion of the outer end of the
frame T3 again throws the two series of gears into mesh and withdraws the locking
cross bar from the upper series of gears, as will be readily understood.
In order that the gears 2, 5, 8, 11 may not become displaced after they have once
been set and before they are moved again into mesh with their co-operating gears,
I provide each of said gears 2, 5, 8 and 11 with a frictional locking device,
consisting of a small bell crank lever mounted loosely upon a cross bar T8 of the
movable frame T3 and having one of its arms, the upper one, formed with a friction
surface T and its lower arm To somewhat prolonged so as to extend beneath a
cross bar T extending between the fixed arms T' T'.
A spring T applied to each of these bell crank levers operates normally to keep
the long arm pressed upward against the fixed cross bar T" and to keep its arm
carrying the friction surface T in proximity to, though not in contact with the
surface of the registering gear above it. When however the frame T is lowered
by manipulating the adjusting means To the bell crank levers are permitted a
greater range of movement and their springs force the friction surfaces T into
contact with their respective registering wheels and hold them from moving except
when positively turned by the operator in setting them. On the return of the
frame T3 to normal position the long arms T of the levers strike the cross
bar T and draw the friction surfaces T out of contact with the registering
wheels.
of
The gears 3 and 4 of the upper set are rigidly secured together and are
practically the same as a single wide gear. The same is true of the gears 6 and 7
and the gears 9 and 10. The part 4 of the first gear meshes with the gear
the second registering wheel of the lower set as shown in Fig. 1 while the part 3
of the gear is in the same plane as the transfer locking disc a secured to the left
side of the first registering wheel Fig. 9. The periphery of the disc a fits closely
against the teeth of the gear 3 and prevents the latter being turned. The disc a
has a single tooth a' on its periphery and when the first registering wheel has been
turned one complete revolution, this tooth enters between two of the teeth of the
gear 3 and turns the latter, and the gear 4 rigid with the gear 3, and meshing with
the gear 5 of the second registering wheel turns the latter one number and effects
the transfer from the first registering wheel.
The gear 3 is mutilated every third tooth being cut away, leaving its teeth in
pairs with a space between each pair. This permits the gear to be turned by the
tooth on the disc a which at other times locks the gear from movement.
Each of the gears 6 and 9 is like the gear 3 and co-operates with a transfer locking
disc on the preceding registering wheel of the lower set in the same manner.

page_text: Inasmuch as it is impossible when the gears of the upper set are in mesh with those
on the registering wheels to turn the gears of the upper set except by the toothed
discs on the wheels of the lower set and inasmuch as the gears of the upper set are
automatically locked by the rear cross bar Ts of the swinging frame Figs. 9 and 10
whenever the wheels of the lower set are disengaged from them, it follows that the
continued revolutions of the gears of the upper set, adding one on to the other,
preserve and aggregate an unchangeable record of the revolutions of the wheels of
the lower set, so that while the latter may be reset to zero the former cannot be,
and by providing them with suitable numbers the total of all registrations made by
the wheels of the lower set may be carried on those of the upper set indefinitely.
Having thus described the various parts of the registering mechanisms it will next
be in order to explain how said mechanisms are operated by the movement of the
finger keys see Figs. 1, 2, 3, 4, 5, 16 and 18.
The finger keys are lettered U and are all mounted side by side so as to turn
freely upon a common shaft extending across the machine at the front, and they are
provided on their outer ends with finger buttons bearing numbers corresponding to
the values to be registered all as usual in this class of machines.
Each key, back of its pivotal point is provided with a wedge shaped projection U₁
Fig. 2 which works within a vertical slot V₁ in what may be termed a slide box V
extending transversely of the machine above the keys, the said wedge shaped
projection normally occupying the lower portion only of said vertical slot. Within
the slide box V are arranged two series of slides, one series 13, 14, 15, 16, 17,
occupying with suitable intervening fixed spacing plates the right hand end of the
box beneath the cent registering mechanisms, and the other series 18, 19, 20, 21, 22
occupying, with their intervening spacing plates, the left hand end of the box beneath
the dollar registering mechanism. The outer ends of the slides 13, 14, 15, 16, 17
project through the ends of the box and against them bears a spring V³ which tends
to keep them retracted within the box though permits them to move a limited
distance outward against the tension of said spring. Another similar spring U³
operates against the end of the other series of slides 18, 19, 20, 21, 22.
Each slide has portions of its underside cut away, to form pendent lugs V4 Fig. 18
there being one lug for each key with which the slide co-operates. Thus the slide 13
shown in Fig. 18 is called the five cent slide and co-operates with each odd
numbered key from 5 to 95 to shift the five cent escapement wheel J' in the manner
hereinafter described when any one of such keys is operated. As there are ten of
such odd numbered keys there are accordingly ten of such lugs V₁ on the under side
of the slide 13 shown in Fig. 18 and one of these lugs projects from the right into
the slot above each of said keys in the path of the wedge on said key.
The lugs on the ten cent slide 14 project into the slots of the 10, 15, 30, 35, 60,
65, 80 and 85 cent keys see Fig. 16 those on the twenty cent slide 15 into the slots
of the 20, 30, 40, 45, 80, 90 and 95 cent keys, those on the second twenty slide 16
into the slots of the 25, 35, 40, 45, 70, 75, 85, 90 and 95 cent keys, while those on
the fifty cent slide 17 project into the slots of all the keys from 50 to 95 cents
inclusive.
It results from the above arrangement of the lugs on the slides that when the
outer end of a key is depressed its wedge shaped projection U' will rise up in the
appropriate vertical slot V₁ and will encounter the projecting lug of one or more of
the slides and force said slide or slides longitudinally against the tension of its
retracting spring, while the other slides will remain stationary, and upon the return
movement of the key and consequent withdrawal of the wedge shaped projection,
the said spring will again retract the slide or slides and return it or them to normal
position.
The movements of the slides 13, 14, 15, 16, 17 on the right hand side of the
machine are communicated through centrally pivoted vibrating levers 23, 24, 25,
26, 27 to the several escapement wheels J, J, J³, J, J' of the cent registering
nechanism, while the movements of the slides 18, 19, 20, 21, 22 on the left hand of
he machine are communicated through corresponding centrally pivoted vibratory

page_text: levers 28, 29, 30, 31, 32 to the several escapement wheels N' N³ N' N' No of the
dollar registering mechanism the lower end of each of said centrally pivoted levers
being connected by a hinged or flexible connection to the corresponding slide, and
the upper end of said lever, which is preferably bifurcated or forked, co-operating
within a peripheral groove in the hub of its corresponding escapement wheel, as
clearly shown in Figs. 1 and 2.
Assuming both the cent registering wheel and the dollar registering wheels to be
at zero and that it is desired to register a five cent sale, the operator presses upon
the five cent key (marked with a large five in the drawing) which causes the wedge
shaped projection on that key to move the slide 63 to the right, against the tension
of spring U2 a distance sufficient to cause the vibratory lever 27 to shift the escape-
ment wheel J laterally, so as to disengage one of its teeth from the outer contact
of the stationary detent L' and allow said escapement wheel to turn till its next
tooth comes in contact with the inner contact and then, upon the release of the
key and its return to normal position, the spring U2 will again retract the slide 13,
move the lever 27 and slide the escapement wheel J back to first position, thus
liberating the said second tooth of the escapement wheel from the inner contact l'
of the detent and permitting it to advance to the outer contact I, the result being a
total advance of the escapement wheel the distance being two of its teeth, in other
words, a distance equal to one twentieth of a revolution of the shaft and the registra-
tion of five on the registering wheel H.
If instead of pressing the five cent key, the fifty five cent key is pressed, the
wedge shaped projection on said fifty five cent key will operate not only the fifty
cent slide 17 but also at the same time the five cent slide 13, the result being the
movement of the vibratory levers 23 and 27, the shifting of both escapement wheels J
and J and the consequent registration of fifty five in the registering wheel H.
When it is understood that the slide 13 operates the five cent escapement wheel J³;
the slide 14 the ten cent escapement wheel J; the slide 15 the twenty cent
escapement wheel J³, the slide 16 the other twenty cent. escapement wheel J2 and
the slide 17 the fifty cent escapement wheel J, it will be obvious that in order to
cause a key representing any multiple of five up to ninety five to operate the appro-
priate escapement wheel or combination of escapement wheels representing that
value, it is only necessary to so arrange the slots in the slides that when the par-
ticular key is pressed its wedge shaped projection will operate upon and shift
longitudinally as many slides as will move the escapement wheels representing the
desired combination, for instance the five cent key must move the five cent slide 13
and that only; the ten cent key, the ten cent slide 14 and that only; the fifteen
cent key both the five cent slide 13 and the ten cent slide 14; the twenty cent
key the twenty cent slide 15 and so on, till we come to the ninety five cent key,
which must move the fifty cent slide 17 the twenty cent slide 15; the second twenty
cent slide 16 and the five cent slide 13.
In like manner combinations are made of the slides of the dollar registering
mechanism, one of said slides representing one dollar, another two dollars, another
four dollars, another five dollars and the remaining one ten dollars.
In my prior Patent before referred to each key was connected with only one
escapement wheel, and there were as many escapement wheels as there were keys.
By combining two or more escapement wheels with a single operating key as I have
done in my present machine, I am enabled to form combinations by which on the
cent side of the machine, the values of nineteen different operating keys may be
accurately registered on the registering wheel with the employment of only five
escapement wheels and their co-operating detents. This part of my present
invention constitutes one of the most valuable improvements upon my prior machine
and the essential feature of it consists in the combination of two or more escape-
ments and their co-operating detents, with a single key, so that when said key is
operated, both escapments will be disengaged from their detents and the sum of
their movements transferred to the registering wheel.
Instead of employing springs to return the slides to normal position after they

page_text: have been moved outward by the action of the wedge shaped projections on the
keys a swinging bar K having wedge shaped cams K" on its outer ends for
co-operating with the ends of the slides, may be employed as shown in Fig. 11.
In this modification the swinging bar is designed to be lifted by the keys and the
wedge shaped projections in the keys shift the slides outward as the wedge shaped
cams on the swinging bar are retracted. As the keys return to normal position the
As is usual
operation is reversed, the slide being driven in by the falling cam K".
in improved machines of this class, there is arranged above the keys and in rear of
the shaft upon which they are pivoted the bar A', Figs. 4, 5 and 16 extending
transversely across and resting upon the tops of all the keys and connected by
suitable arms A' to a pivot shaft A so as to be free to turn with the latter in its
bearings. The rear edge of said transverse bar normally stands opposite horizontal
slots A made at or near the bases of projections A³ formed on the tops of the keys,
and when a key is pressed so as to raise its rear end, the transverse bar is raised with it
and owing to the fact that the key and transverse bar are pivoted on different
centres, the edge of the transverse bar enters the slot A of the key projection A*
and during the rest of the upward movement of the key and in fact till its first
position has been resumed, the key and transverse bar remain securely locked
together. As the transverse bar swings up it moves out over the projections A³ of
the unoperated keys and prevents any one of them from being raised till
the key with which it is engaged is returned to normal position and released.
Connected to the transverse bar A' at A' is a bell crank lever A' pivoted at A³
and having an arm A' which is adapted to bear upon one end of a pivoted
lever A that carries at its opposite end a bolt A" by which the cash drawer A¹
is locked.
Whenever a key is operated, the arm A of the bell crank lever is depressed
thereby tilting the lever A10 against the tension of its spring A13 and raising the
locking A from engagement from its keeper A" in the drawer, thus allowing the
drawer to be projected forward or opened by the action of a stout spring A1
arranged behind it as shown in Fig. 12.
The lever B by whose vibrations the spring drum winding appliance of the
registering mechanism is actuated, is connected, it will be remembered, by a pin
and slot connection to the slide B that works upon the guide rod B' and the
forward or return motion is given said lever and slide by the action of the spring B
as shown in Fig. 3. Now in order that the requisite backward or winding
movement may be given said lever and slide, I provide the slide with a downward
projection or arm 13 made long enough to extend down into the path or behind
the drawer A12 so that each time the drawer is closed, the said slide and lever B³
will be actuated so as to wind up the spring drums, while upon the opening of the
drawer the spring B8 will re-set and restore the parts ready for the next operation.
In order that there be given the drawer in closing it an amount of motion sufficient
to impart the proper length of stroke to the lever B³, I have provided the drawer
with an appliance which requires that when the drawer has once started to open it
cannot be pushed backward or returned but must continue to move outward until
Such appliance is
it is fully opened thereby ensuring a full stroke on the return.
illustrated in Figs. 12, 13, 14 and 15 and consists of a guide or way W secured to
the case of the machine beneath the drawer and provided on its interior with a
ratchet bar W₁ formed upon or secured to one of its sides at its rear end and
provided further with a longitudinal groove W' in its bottom extending from end to
end of it as shown in Figs. 14 and 15. Within the longitudinal groove W' fits, so
as to freely move back and forth therein, a slide W which is formed with a
recess Win its top near its middle and has hung upon or pivoted to its side next
to the ratchet bar W₁, a pawl W whose long arm is provided with a tooth W and
whose short arm is formed on its top with a cam shaped recess W as shown.
Upon the bottom of the drawer is secured a bar X that is adapted to slide back and
forth within the stationary guide W and is provided with a downwardly projecting
lug which extends down within the recess W of the plate or pawl carrier, and
B

page_text: is further provided with a √ shaped projection X² which extends down within the
cam shaped recess W7 of the pivoted pawl.
The projecting lug X' of the sliding bar X is not so wide as the recess W of
the pawl carrier Wand when the drawer is closed rests at the rear side of the
recess W₁ as shown in Fig. 12. Consequently when the drawer and bar X are
removed outward there is at first a slight amount of lost motion between the lug X¹
and the forward wall of the recess W₁ during which the V shaped projection X2
strikes the forward wall of the cam recess W' and raises the rear toothed end of
the pawl W above the rear end of the ratchet bar W'..
As the drawer is pulled outward the pawl tooth remains in this elevated position
and free from the teeth of the ratchet bar. If however before the pawl passes
beyond the front end of the ratchet bar any attempt to close the drawer is made,
the lost motion between the lug X¹ on the bar X and the rear wall of the recess W
in the pawl carrier W³ will cause the V shaped projection X' on the bar X to
release the pawl W' and permit the toothed rear end to drop into engagement with
the ratchet bar, and prevent further inward motion. After the drawer has been
sufficiently opened to carry the pawl Ws beyond the front end of the ratchet bar
the first inward movement of the drawer will release the pawl, in the manner
described, and its rear toothed end will drop below the front end of the ratchet bar
and the drawer is free to be closed.
From this description it will be clear that in closing the drawer, the toothed end
of the pawl will pass beneath the ratchet bar as illustrated in Fig. 12 and not
impede in the slightest the backward movement of the drawer thereby enabling the
drawer to be pushed in and automatically locked by the locking bolt as ordinarily,
or pushed in part way and then opened, but after the drawer is fully pushed in and
locked, the moment it is again unlocked and starts to move outward, the toothed
end of the pawl will be lifted above the ratchet bar and, while the drawer may
continue its outward movement without obstruction, any effort to push it back
before it is fully opened will cause the pawl to dog into the ratchet bar and hold
the drawer fast. A backward movement of the drawer is thus insured each time
sufficient to keep the spring drums of the registering mechanism always properly
wound up.
It is desirable in machines of this class, that when a key has commenced to move
in one direction it shall be required to fully complete its movement in that direction
before it can be returned wholly or partially to normal position or the starting
point, also, that when a key has so made a complete movement in one direction it
shall be required to make a complete return movement back to the starting point
before it can be again advanced wholly or partially, and while I do not claim to be
the original projector of the broad idea of providing for appliances for effecting
such desirable results, I have in the construction of this machine devised special
appliances which admirably accomplish the object and which I believe to be new.
I will now describe them.
Pivoted to one side of the frame of the machine at Y is a swinging arm Y¹that
is provided with a ratchet segment Y2 whose teeth point upward and with another
ratchet segment Y³ whose teeth point downward. The ratchet segment Y2 which
for brevity I will hereinafter call the ratchet Y2 simply, is adapted to co-operate
with a tooth Z on one of the arms A2 of the transverse bar A' and the ratchet Y³
is adapted to co-operate with another tooth Z' on said arm A². A pin Y projects
from the outer side of the arm Y into the path of the winding lever B³ and when
said lever is thrown backward, it is when the cash drawer is closed, it strikes said
pin Y and, overcoming the tension of a forward drawing spring Yo swings said
arm backward so as to throw both its ratchets Y2 and Y3 out of engagement
with their co-operating teeth in the arm of the transverse bar. When however a
key is pressed and the drawer is liberated the winding lever 133 swings forward,
thus releasing the arm Y¹ which thereupon also swings forward until its foremost
ratchet Y comes in contact with the tooth Z on transverse bar which latter by this
time has become locked to the operated key and is rising with it. As the rear end

page_text: of the key and transverse bar continue to rise the tooth Z slips over the upwardly
pointing teeth of the said ratchet Y2 but the moment pressure on the key ceases or
a contrary movement of the key is attemped said ratchet catches said tooth and the
transverse bar and ratchet become locked together.
Just before the rear end of the key reaches the limit of its upward movement the
tooth Z passes off the ratchet Y' and the spring Y draws the swinging arm Y¹
forward till it brings the second ratchet Y³ with the downwardly pointed teeth up
against the other tooth Z' of the transverse bar and when by the removal of
pressure from its outer end, the inner end of the key and the transverse bar move
downward to first position, the said tooth Z' runs easily over the ratchet Y³ which
offers practically no obstruction to its motion but if, before, the key has fully
returned an attempt is made to again operate it the tooth Z' will dog into the
ratchet Y3 and arrest the movement.
The ratchet Y³ remains in engagement with the tooth Z' until the closing of the
cash drawer causes the swinging arm bearing said ratchet to be swung back out of
the way.
It will thus be seen that the ratchet Y3 by thus holding down the
transverse bar till the drawer is closed operates to prevent the operation of any key
of the machine while the drawer remains open.
In establishments where machines of this class are used, it is sometimes desirable
to open the cash drawer for the purpose of withdrawing a sum of money and
substituting therefor a check, indicating the amount taken out or of withdrawing
such check and returning the money or the like, without making a registration
upon the ordinary registering devices. Therefore to make provision for such a
use of the present machine and yet keep a record of the number of times the
machine is so used, I provide an extra key Z³ preferably alongside the ten dollar
key which extra key has no connection with the slides which operate the registering
mechanism herein before described, though it is adapted to actuate a tablet rod
bearing a tablet lettered check and operates upon the transverse bar so as to
sound the alarm apparatus when actuated; and I arrange in connection with said
extra key a separate registering mechanism consisting of a series of wheels 30. 31. 32
Figs. 20 and 21 mounted loosely upon a shaft 33 and another series of co-operating
wheels 34 and 35 mounted, the first rigidly, and the second loosely, upon a shaft 36
and also secure to the shaft 36 a ratchet wheel 37 with which is adapted to
engage a spring pawl 38 mounted upon a plunger 39 whose lower end bears on top
of the extra key 73. Each time the key is operated to open the cash drawer,
the plunger 39 is caused to rise against the tension of the spring 50 and its pawl
advances the shaft 36 the distance represented by the length of one ratchet tooth,
which advance is recorded on the wheel 30 and transferred in due course to the
wheels 31 and 32.
A spring 40 prevents any backward movement of the ratchet wheel 37 except
when said spring is thrown out as it may be by a cam arm 41 mounted on the
shaft 36 for the purpose of resetting the register.
I have shown the toothed rods and indicating tablets and the means for operating
them, also the bell and bell sounding mechanism but have not deemed it necessary
to describe said parts of the machine as they do not differ essentially from those
now in general use.
