COMPLETE SPECIFICATION.
Improvements in Coin Displayers for Cash Registers and Check Tills.
We, THE NATIONAL CASH REGISTER COMPANY LIMITED, of 337, Strand, in the
County of London, Manufacturers, do hereby declare the nature of this invention a
communication 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 improvements in cash registers and has more particular
relation to improvements in coin displayers for the same.
The primary object of the invention is the application of an improved form of
coin displayer to a cash register. We have shown our invention as applied to a
machine of the class in which a rotary shaft is revolved by mechanism as herein-
after described but we do not limit ourselves to such application as our invention
may be applied with equal facility to any cash register containing a rotary
shaft.
In the accompanying drawings forming part of this specification.
Fig.1 represents a transverse vertical section through the devices embodying our
invention applied to a cash register of the type mentioned.
Fig. 2 represents a top plan view, partly in section and partly broken away, of
the same, and
Fig. 3 represents a vertical transverse section taken on a different line from
Fig. 1, the cash drawer being omitted.
In the said drawings represents the frame of the machine; 2 the operating
keys; the rotation shaft; 4 the coin receiving pockets; and 5 the extra
money drawer.
The operation of the amount keys in connection with the rotation shaft 18
substantially similar to that of the before mentioned type of machine and may be
described as follows:-Each key 2 is pivotally mounted upon a transverse shaft 6
and is adapted, when operated to raise and lower a key coupling frame 7 pivotally
mounted in the main frame so as to extend above all of the keys to the rear of
the journal shaft 6. The said frame 7 is provided at one end with an anti-
friction roller 8 which projects into a transverse slot 9 formed in a vertically

guided in its movements by a pin 8" mounted on the main frame and projecting
into a guiding slot 8b formed in said bar. This bar is further formed with a
vertical slot 11 having gear teeth 12 formed on its walls and adapted to engage
a pinion 13 which projects into said slot but is only of sufficient diameter to engage
one set of gear teeth at a time. This pinion is mounted rigidly upon a rotation
shaft 3 so as to impart its motion to the same. The upper portion of the bar 10
is provided with two spring pressed plungers 15 arranged upon opposite sides of
the same and adapted to bear respectively against incline flanges 16 rigidly mounted
upon the main frame. This bar is further provided near its upper end with a
laterally projecting stud 17 having upper and lower incline sides and arranged to

page_text: co-act with a vertical flange 18 mounted on the main frame. By this peculiar
structure the shaft 3 is given a rotary movement as the bar 10 moves up and
down as first one set of gear teeth engages the pinion 13 and then the other. As
the bar moves up the stud 17 rides in iront of the flange 18 but when it reaches the
top of the same it is forced over, by the forward spring pressed plunger which has
meanwhile been compressed by its incline flange 16, so as to travel down upon
the opposite side of said flange 18. The remaining soring pressed plunger then
forces it at the end of its lower stroke into its normal position ready for the next
operation of the machine. The devices above described are old and are simply
described to more clearly demonstrate the operation of our improved devices in
connection with this class of machine. The extreme outer end of the shaft 3 is
provided with a gear wheel 19 fast thereto and adapted to actuate a similar gear 20
through an intermediate gear 21 which latter is suitably journaled on the main
frame. The said gear 20 is fast upon a short shaft 22 journaled in the auxiliary
coin displayer casing 23 which is suitably secured upon the main frame.
This shaft 22 as well as a similar shaft 24 mounted near the lower end of the casing 23
is provided with a sprocket wheel 25; an endless sprocket chain or belt 26 passing
about said wheels. This chain supports a number of metallic pockets or coin
receptacles 4 which are riveted fast to the links of said chain so as to move
therewith. The projecting sides of said receptacles of the upper half of the chain
rest upon side flanges 28 of the casing 23 and thus hold all the receptacles which
are in view and contain coins, straight in relation to the casing and in relation to
each other. The upper incline portion of the casing 23 is provided with a hinged
cover 29 having a glass covered sight aperture through which all the coin receptacles
upon the upper half of the chain may be seen. The lower end of this cover is
arranged to be engaged by a spring latch 30ª mounted within the drawer casing 31"
of the auxiliary drawer so that none save those having access to said drawer
can release the latch and open the cover. A coin chute 30 is also arranged near the
top of the casing 23 to guide the coins inserted, into the uppermost receptacle. In
order to prevent the coins from dropping back in the casing or being inserted at a
time when there is no receptacle in the proper position to receive them we provide
a pivoted lip or guard 31 within the casing 23 immediately below the
chute 30. The position of this guard is such that when a receptacle is turning
about the upper sprocket wheel with the chain it strikes and forces the lip upward
and thus closes the chute until said receptacle has reached a position in which it
is ready to receive the coin when the lip again descends and acts as a guide to cause
the coin to pass smoothly into said receptacle. The movement of the chain at
each operation of the keys and rotary shaft as above described is just sufficient to
bring a fresh coin receptacle into position to receive the coin. As
a coin passes downward with the chain it is visible through the
glass cover for four successive operations of the machine and when the
receptacles turn over the lower sprocket wheel the coins therein fall
through the lower open bottom of the casing into the auxiliary cash drawer 5 from
which they may be removed by the person having access thereto.
By the employment of this device there can be no mistake as to the amount of
money received as the coins remain in sight after being placed in the displayer for
four consecutive operations.
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. In a cash register, the combination with the operating mechanism, of an
endless coin conveyor, substantially as described, means for inserting coins into
the same, and devices connecting said operating mechanism and conveyor.
2. In a cash register, the combination with the operating mechanism, of an
endless coin conveyor, substantially as described a coin chute discharging upon
said conveyor, and means connecting said operating mechanism and conveyor.
