We, THE NATIONAL CASII REGISTER COMPANY LIMITED, of 356, Strand, London,
W.C., Manufacturers, do hereby declare the nature of this invention, a communica-
tion to us from abroad The National Cash Register Company, of Dayton, State
of Ohio, United States of America, to be as follows:-
This invention relates to an improved coin displayer and its object is to provide
more convenient and efficient means than have been heretofore available.
It is most advantageously used in connection with a cash registering machine.
It is arranged to be secured to the case of an ordinary cash register, preferably at
one end thereof, and to be operated step by step as the keys of the register are
pushed upon.
It is immaterial with what style of register this coin displayer is employed, it
being only requisite that it is one in which the registering mechanism is actuated
by key levers and hence it will be unnecessary for the present purposes to more
particularly describe the register except in so far as it co-operates with the
improved coin displayer.
A supplemental cash drawer is secured to one end of the register body in the
same plane as the drawer of the register but not communicating therewith. A
bracket, located above said supplemental drawer supports the coin displayer wheel.
This bracket is in the form of a hollow metal casing within which is the mechanism
which is actuated by the universal key bar, through intermediate means, to operatė
the displayer.
The displayer frame, is secured to the body of the register and to the bracket
and at its top is provided with an opening, adapted to receive a corn, and at its
bottom with an opening through which the coins pass into the additional drawer
beneath. This frame is preferably of metal, but its faces are open or covered with
glass or other transparent material so that the display wheel within will always
be visible. The display wheel is journaled near the outer edge of the bracket.
within the displayer frame. The wheel is a circular metal plate or disc which is
cut away at several places from its circumference to points intermediate between
the same and its centre, the parts cut away being approximately semi circular in
shape and at equal distances apart, so that separating the spaces cut away are left
arms between which the coins are held. In connection with this display wheel
and frame, reference may be made to the English Patent No. 20,060, dated
November 7, 1892 which shows a construction similar to that of the device herein
described. In that patent the displayer frame and wheel are shown located close
to and parallel with the side of the register in connection with which it is used.
It is here preferred to have the corresponding parts of the present device located
at substantially right angles to the body of the register, as one is thus enabled to
employ more efficient operating mechanism between the register universal key
bar and the display wheel. In the patent referred to the coin displayer is operated
by the movement of the cash drawer, whereas in the present device the displayer

page_text: is actuated by the operation of the register keys. This intermediate mechanism
will now be particularly described.
Secured to the axle of the display wheel which is journaled in suitable bearings
in the bracket and within the said bracket, is a ratchet. Pivoted within the bracket
at opposite sides of the ratchet are pawls. The one pawl is normally held by a
spring seated against a tooth of the ratchet to prevent backward rotation of the
same. Located within the bracket case near the inner edge of the same and the
body of the register, is a vertical bar, adapted to slide between horizontal guide
plates, near the top and bottom of the bracket case respectively. Secured fast to
this sliding bar, is a short cross bar, extending at right angles therefrom, through
an opening in the side of the register case, into said case, and co-operates with
levers within the same, connected with the universal key bar. On the sliding bar
beneath the cross bar, is pivoted a lever which extends diagonally to the ratchet
and is held in position by a pin, secured to the bracket, upon which the lever rests
near its outer end. The outer end of this lever is pointed, being adapted to engage
the teeth of the ratchet. The lever is notched at a point adjacent to the cross bar,
so that they will not conflict when the parts are operated. Above the cross bar on
the sliding bar is a substantially triangular shaped plate pivoted at one of its
corners to said sliding bar. The other pawl herein before referred to, which engages
the ratchet has an arm extending toward the sliding bar. On this arm is a project-
ing lug near its outer end. One of the corners of the said triangular plate seats
against this lug on the arm of the pawl. The third corner of said plate seats
against a lug or bulge on the side of the bracket adjacent to the register case.
The lower end of the sliding bar normally rests on the upper face of the coin box
beneath the displayer. To prevent its accidental displacement, a coil spring, is
located near its upper end between the guide, plate and projecting pin on the sliding
bar.
The means preferably employed to communicate motion from the universal key
bar of the register to the coin displayer mechanism are as follows:-A substantially
horizontal lever is pivoted near the bottom of the inner side of the end of the
register case adjacent to the coin displayer and near the front of the case.
This
lever extends rearwardly, parallel with the end of the register, case, to a point
beneath the universal key bar where it is pivoted to a second lever which is pivoted
at its opposite end to the said universal key bar. A third lever pivoted to the
first lever midway between its ends, extends upwardly and connects with the cross
bar secured to sliding bar before referred to. The sliding bar is thus moved
upwardly each time a key is operated, for the purpose herein before specified.
When a register key is pressed upon to register a scale the intermediate mechan-
ism between the universal key bar and the cross bar on the sliding bar causes the
said sliding bar to slide upwardly through its guide plates against the tension of
the spring. The upward movement of the sliding bar communicates motion to
the diagonal lever and triangular plate which are pivoted thereon, the said lever
being pressed against the ratchet and causing it to move the display wheel one step
forward. The coin compartments of the display wheel are thus brought succes-
sively into register with the coin opening in the top of the displayer frame. The
upward movement of the sliding bar causes the triangular plate (which normally
serves to lock the ratchet by pressing against the lug on the arm of pawl) to push
said pawl close against the ratchet simultaneously with the forward movement of
the ratchet communicated by the lever moves said plate upwardly from its normal
position between lugs thus unlocking said ratchet and permitting it to move for-
ward one step each time a register key is operated.
When a sale is made the purchase money is first placed into the coin displayer
through the slot at the top of the same. The corresponding register key is then
pushed upon this operation moving the display wheel one step forward by means
of the mechanism herein before described, thus bringing the next coin compartment
of the display wheel into register with the entrance slot, and keeping the deposited

page_text: coin in sight during the next three steps of the display wheel through the trans-
parent sides of the displayer frame or coin compartments, but inaccessible; and
finally depositing the same, through the discharge opening in the bottom of the
displayer frame or bracket, into the cash drawer beneath. Thus the gross receipts
during the day are kept separate from the money in the change drawer of the
register, as well as the coin received kept visible during several successive sales,
so that no dispute can arise as to the coin received..

An Improved Coin Displayer.
We, THE NATIONAL CASH REGISTER COMPANY LIMITED, of 356, Strand, London,
W.C., Manufacturers, do hereby declare the nature of this invention, a communica-
tion to us from abroad by The National Cash Register Company, of Dayton, State
of Ohio, United States of America, and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
This invention relates to an improved coin displayer and its object is to provide
more convenient and efficient means than have been heretofore available.
This invention is illustrated in the accompanying drawings in which the
improved coin displayer is shown in connection with a cash registering machine,
in which manner it is most advantageously used. It is arranged to be secured to
the case of an ordinary cash register, preferably at one end thereof, and to be
operated step-by-step as the keys of the register are pushed upon.
It is immaterial with what style of register this coin displayer is employed, it
being only requisite that it is one in which the registering mechanism is actuated
by key levers, and hence it will be unnecessary for the present purposes to more
particularly describe the register except in so far as it co-operates with the
improved coin displayer.
Like reference letters are used to designate identical parts throughout the
several figures of the drawings, in which-Fig. 1 is a perspective view of the
improved coin displayer as applied to a cash register. Fig. 2 is a vertical longi-
tudinal section of the displayer and adjacent portion of the cash register, along the
line indicated by line 3-3 in Fig. 3, and Fig. 3 is a vertical transverse section
along the line indicated by line 2-2 in Fig. 2.
A, is a supplemental cash drawer secured to one end of the register body in
the same plane as the drawer of the register but not communicating therewith.
B, is a bracket, located above said supplemental drawer which supports the coin
displayer wheel. This bracket B, is in the form of a hollow metal casing within
which is the mechanism which is actuated by the universal key bar, through inter-
mediate means, to operate the displayer C, is the displayer wheel frame, and D the
wheel.
The displayer frame C is secured to the body of the register and to the bracket, B
and at its top is provided with an opening a, adapted to receive a coin, and at its
bottom with an opening through which the coins pass into the additional drawer A,
beneath. This frame C is preferably of metal, but its faces are open or covered
with glass or other transparent material so that the display wheel within will always
be visible. The display wheel D, is journalled near the outer edge of the
bracket B, within the displayer frame C. The wheel D, is a circular metal plate

page_text: or disc which is cut away at several places from its circumference to points inter-
mediate between the same and its centre, the parts cut away being approximately
semi-circular in shape and at equal distances apart, so that separating the spaces
cut away are left arms between which the coins are held. In connection with this
display wheel and frame, reference may be made to the English Patent No. 20,000,
dated November 7, 1892, which shows a construction similar to that of the device
herein described. In that patent the displayer frame and wheel are shown located
close to and parallel with the side of the register in connection with which it is
used. It is here preferred to have the corresponding parts of the present device
located at substantially right angles to the body of the register, as one is thus
enabled to employ more efficient operating mechanism between the register
universal key bar and the display wheel. In the patent referred to the coin dis-
player is operated by the movement of the cash drawer, whereas in the present
device the displayer is actuated by the operation of the register keys. This inter-
mediate mechanism will now be particularly described.
Secured to the axle of the display wheel which is journaled in suitable bearings
in the bracket B, and within the said bracket B is a ratchet b. Pivoted within
the bracket B at opposite sides of the ratchet bare pawls and d. The one pawl c
is normally held by a spring e, seated against a tooth of the ratchet, to prevent
backward rotation of the same. Located within the bracket case near the inner
edge of the same and the body of the register, is a vertical bar E adapted to slide
between horizontal guide plates ee, near the top and bottom of the bracket case
respectively. Secured fast to this sliding bar E, is a short cross bar F, extending
at right angles therefrom, through an opening in the side of the register case, into
said case, and co-operating with levers within the same, connected with the univer-
sal key bar. On the sliding bar E, beneath the cross bar F, is pivoted a lever G,
which extends diagonally to the ratchet b, and is held in position by a pin x, secured
to the bracket, upon which the lever rests near its outer end. The outer end of
this lever G is pointed, being adapted to engage the teeth of the ratchet b. The
lever G is notched at a point adjacent to the cross bar F, so that they will not con-
flict when the parts are operated. Above the cross bar F, on the sliding bar E,
is a substantially triangular shaped plate H pivoted at one of its corners to said
sliding bar E. The other pawl d, herein before referred to, which engages the
ratchet 6 has an arm f extending towards the sliding bar E. On this arm f is a
projecting lug g, near its outer end. One of the corners of the said triangular
plate H seats against this lug g, on the arm f, of the pawl d. This third corner of
said plate H seats against a lug or bulge h on the side of the bracket B adjacent to
the register case.
The lower end of the sliding bar E normally rests on the upper face of the coin
box beneath the displayer. To prevent its accidental displacement, a coil spring i
is located near its upper end between the guide plate d and projecting pin K, on
the sliding bar E.
The means preferably employed to communicate motion from the universal key
bar of the register to the coin displayer mechanism are as follows:-A substan-
tially horizontal lever X, is pivoted near the bottom of the inner side of the end of
the register case adjacent to the coin displayer and near the front of the case.
This lever extends rearwardly, parallel with the end of the register case, to a point
beneath the universal key bar where it is pivoted to a second lever Y, which is
pivoted at its opposite end to the said universal key bar. A third lever Z pivoted
to the first lever X midway between its ends, extends upwardly and connects with
the cross bar F, secured to sliding bar E before referred to. The sliding bar E is
thus moved upwardly each time a key is operated, for the purpose herein before
specified.
From the foregoing description and by reference to the accompanying drawings,
the operation of this coin displayer will be evident. In order, however, that it may
be more clear, the operation of the improved device is as follows:-

page_text: When a register key is pressed upon to register a sale, the intermediate mechan-
ism between the universal key bar and the cross bar F, on the sliding bar E, causes
the said sliding bar E to slide upwardly through its guide plates ee against the
tension of the spring i. The upward movement of the sliding bar E, communicates
motion to the diagonal lever G and triangular plate H which are pivoted thereon,
the said lever G being pressed against the ratchet b, and causing it to move the
display wheel one step forward. The coin compartments of the display wheel D
are thus brought successively into register with the coin opening in the top of the
displayer frame. The upward movement of the sliding bar E causes the triangular
plate H (which normally serves to lock the ratchet by pressing against the lug g on
the arm f of pawl d,) to release the said pawl simultaneously with the forward
movement of the ratchet communicated by the lever G since the said upward move-
ment of bar E moves said plate H, from its normal position between lugs g and h
thus unlocking said ratchet b and permitting it to move forward one step each time
a register key is operated.
When a sale is made the purchase money is first placed into the coin displayer
through the slot at the top of the same. The corresponding register key is then
pushed upon, this operation moving the display wheel one step forward by means
of the mechanism hereinbefore described, thus bringing the next coin compartment
of the display wheel into register with the entrance slot, and keeping the deposited
coin in sight during the next three steps of the display wheel through the trans-
parent sides of the displayer frame or coin compartments, but inaccessible; and
finally depositing the same, through the discharge opening in the bottom of the
displayer frame or bracket, into the cash drawer beneath. Thus the gross receipts
during the day are kept separate from the money in the change drawer of the
register, as well as the coin received kept visible during several successive sales,
so that no dispute can arise as to the coin received.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim
is:-
1. The improved coin displayer comprising a case with transparent sides having
within it a coin display wheel, the operative mechanism of which is so connected
with means operated by the keys of a cash register that the wheel is turned for a
certain distance whenever any of the cash register keys is pushed upon substantially
as set forth.
2. The improved coin displayer comprising a case standing away perpendicularly
from the side of a cash register and having beneath it a cash receptacle independent
from the cash drawer of the register, the said case having transparent sides
and within it a coin display wheel the operative mechanism of which is so con-
nected with means operated by the keys of a cash register that the wheel
is turned for a certain distance whenever any of the cash register keys are pushed
upon substantially as set forth.
3. The improved coin displayer comprising the case B wheel D, ratchet b
pawls cf, lever G rod E, and locking piece H and operative gear arranged to act
substantially as and for the purpose set forth.
