Improvements in Coin Weighing and Change Giving Apparatus.
I JOHN ROBERT WARD, of The Chestnuts, The Gore, Darenth, Kent, Mechanical
Expert, do hereby declare the nature of this iuvention to be as follows:-
This invention relates to that class of apparatus whereby change is readily given out
for coins of certain weight previously inserted in the apparatus, and whereby coins of
light weight are rejected.
The object of the invention is to simplify and improve the mechanism of said
apparatus whereby its working is rendered perfect.
My improvements relate more especially to that class of apparatus comprising one
or more circular receptacles contained within a case, and having internal mechanism
consisting of a series of receptacles carried round-when the apparatus is operated-
so as to discharge the contents of each receptacle successively into a chute in exchange
for a coin which has passed the weighing mechanism and thus release the change
giving device.
My improvements relate more especially to the weighing mechanism; but also to
the general arrangement whereby the apparatus is rendered more convenient for use.
By my improvements I place one, two or more apparatus in a box-like case having
openings near its base for the discharge of change and slots for the protrusion of
suitable handles for operating the apparatus.
Two slots enter the casing at the top and lead to the apparatus; one slot for
sovereigns and one for half-sovereigns. Over each of these slots is a suitable slide
which has a slot which registers with the slots in the case when the slide is
pushed back.
Beneath the slot in the casing is a chute having an aperture on one side which is
closed by a hanging door. When a coin enters the chute it falls upon a weighted
lever, and, if of sufficient weight,-depresses it, thereby releasing the remaining
mechanism and falling into the till. If however the coin be of insufficient weight
not depressed but the coin rests eventually on the end thereof and projects
into the chute. A depending lever is journalled to or near the chute and is connected
to the slide aforedescrihed, by a pin, in such manner that when the slide is again
operated the depending lever is rocked and certain projections thereon are caused to
enter apertures in the sides of the chute and thereby force the light coin against the
depending door which, giving way, permits the coin to fall through the aperture it
covers into a chute which leads to the outlet into which the change would have been
delivered had the coin been of good weight
The size of the slots prevents any coins of greater weight than a sovereign or
half-sovereign from being entered therein, and further that when the slide is in such
position that the slots coincide, the projections in the depending lever bar the passage
of the chute; the coins resting upon them until the slide is moved again into its
normal position. These projections therefore prevent the weighing lever from being
depressed by a wire or the like to release the change giving mechanism.

page_text: I, JOHN ROBERT WARD, of The Chestnuts, The Gore, Darenth, Kent, Mechanical
Expert, 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:-
This invention relates to that class of apparatus whereby change is readily given
out for coins of correct weight previously inserted in the apparatus, and whereby
coins of light weight are rejected.
The object of this invention is to simplify and improve the mechanism of the
apparatus so that its working is rendered perfect.
My improvements relate more especially to that class of apparatus having a series
of receptacles arranged in circular form and carried around-when the apparatus is
operated to discharge the contents of each receptacle successively into a chute in
exchange for a coin which has passed the weighing mechanism and thus released the
change giving device.
My improvements relate more especially to the weighing mechanism; but also
to the general arrangement whereby the apparatus is rendered more convenient
for use.
I now proceed to describe my said improvements, reference being had to the
accompanying drawings and to the letters and figures of reference marked thereon,
like letters referring to similar parts throughout.
Fig. 1, is a front elevation, in part section, of so much of an apparatus as will serve
to illustrate my present improvements.
Fig. 2, is a part top view of some of the mechanism shewn in Fig. 1.
Figs. 3, 4, 5 & 6 are detail views.
I place one, two or more apparatus in a box-like case A having openings fitted with
cups B for the discharge and reception respectively of change. The case has also
openings C for the protrusion of suitable handles D for operating the apparatus.
The apparatus comprises a series of circular receptacles E which are radially
arranged within a band F to rotate in intermittent stages over a plate G in which
there is an aperture immediately above a chute H which terminates in the front of
the apparatus in the cup or receptacle B. The receptacles E are connected to
the annular flange I having notches J adapted to be engaged by the rear end of the
weighing lever K pivoted at L to the frame M. When the lever is in its normal
position in the notches J the flange I and receptacles G are locked until released by
the raising of the rear end of the lever by the depression of its forward extremity N
by a coin, of correct weight, resting upon it. When in this position, the flange I and
receptacles E can be rotated one stage, by the manipulation of the handle D to bring
one of the receptacles E over the aperture in the plate to discharge its contents into
the chute H and receptacle B.
Having now described so much of the apparatus as will serve to enable me to
describe the application of my improvements I now proceed to do so.
Suitably secured to the frame M is a rectangular piece of metal O having a groove P
in its face which is covered by a plate Q, preferably secured thereto by screws.
A depending rectangular piece of metal R is provided, and has side arms $, pivoted to
the ends of the block O, and projections T, U, upon its face. These projections enter
openings V in the plate Q. A depending rectangular plate W is pivoted in brackets X
secured to the inner face of the plate. A pins projects from one arm S and
extends through an aperture a, in the casing A, a slot in the block c, and enters the
underside of the sliding block d. The block c is attached by screws or other means
to the lid of the casing A and has a dove-tail groove e in which the lower dove-tail

page_text: part of the block d is adapted to slide. The block d has a slot g which, when the
block d coincides with the block c, registers with a slot h, therein and the slot i in the
lid of the casing A, the slot being situated immediately above the groove P in
the block O. A lever jis pivoted at k to the frame M and is held normally in the
position shewn in Fig. 2, by the spring 1. Screws or pins m are arranged around
the flange I and are adapted to engage the end n of the lever. A chute o is arranged
on one side of the chute H and leads into a drawer Y.
The operation of the mechanism is as follows:-
The receptacles E are each fitted with silver and copper coins amounting to one
sovereign or one half sovereign-there being preferably an apparatus for each gold
coin, arranged in one case. The gold coin is inserted in the slot g whence it passes
through slots hi and groove P (Fig. 3) until it rests upon the projections T as
indicated at q. The block d is then pushed backwards which, by means of pin s,
moves the part R into the position shewn in Fig. 4. The coin then falls onto the
weighing lever at N and, if of correct weight, depresses it, raising its rear end at r
thereby permitting the partial rotation of the receptacles E to release the change into
chute H and cup B. During the movement of the flange I, the forward end of the
lever j moves over the end N of the weighing lever and pushes the coin off it into
chute o whence it falls into the drawer Y. If however, the coin be not of sufficient
weight the lever K is not depressed and the coin remains thereon, as indicated at t
(Fig. 4) until the block d is released, when the spring u, which pulls on one of the
arms s, returns the part R into its normal position as indicated in Fig. 1. The
projections U then press the coin against the hinged piece W which, giving way,
allows the coin to pass into chute H and cup. B without releasing the change.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a coin weighing and change giving apparatus, of that class hereinbefore
referred to and having the annular flange I, the lever pivoted to the frame M, a
spring operating upon said lever, screws m adapted to engage said lever, a chute
arranged as described, all substantially as and for the purposes hereinbefore set forth
and illustrated in the drawings hereunto annexed..
2. In a coin weighing and change giving apparatus of that class hereinbefore
referred to, the mechanism shewn in Figs. 3, 4, 5 and 6 of the drawings hereunto
annexed, substantially as described.
