A New or Improved Apparatus for the Delivery of Change.
I FERDINAND PURVIS of 1^, Coulgate Street, Brockley, S.E. Watchmaker,
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 an improved apparatus by which change can be
obtained on the insertion of a coin, the person requiring change operating the
change giving arrangement by a lever or like device at the outside.
A
A number of shutes or channelled receptacles is employed, corresponding to
the coins to be delivered in change. Thus, for example, if the apparatus is
required to give change for a sovereign this may be made up by one sixpenny
piece, one shilling, three florins, one half sovereign and one half crown, and a
channel would be required for each coin of a size just sufficient to receive a
pile or roll of the required coins. These shutes all slope towards the back of the
apparatus and the end coin rests against a back piece which prevents them
falling through the open end. This support is in the form of a spring at the
end of each shute, so that on a coin being required to fall from the end of a
shute into a receptacle at the bottom, the spring support would give way,
returning immediately the coin had passed and retaining the remainder.
sloping ledge leads the coins thus thrown out to a receptacle at the front of
the machine, where they are removed by the person requiring the change. The
coins are ejected by a series of springs connected to a frame capable of sliding up
and down, the springs lying on the face of the spring supports above mentioned,
and between the latter and the rolls of coins. Each ejecting spring has a projection
on its face, which can engage with the edge of a coin so that when the frame is
pulled down the projections will push down the end coins and throw them on to the
sloping ledge underneath. The frame is operated by a lever passing to the front
of the apparatus and projecting through the case. The lever is normally
disconnected from the sliding frame, so that it is impossible to operate the frame
until a connection is afforded. This is done by the insertion of the coin for which
change is required, which drops through a suitably formed shute, with a device
for detecting light or bad coins, on to the end of a lever at the bottom. This on
falling causes a connection to be made so that when the operating lever is pulled
down it moves the frame and ejects the coins. A special arrangement is provided
for the half sovereign channel, allowing change to be given by the same machine
both for sovereigns and half sovereigns. When a sovereign is inserted, the
complete set of coins is given in exchange, but on the insertion of a half sovereign
through a different shute, the ejecting arrangement for the delivery of those coins
is not operated, it being made quite separate from the frame above mentioned.
The apparatus may be made to give change for any pre-arranged amount, by a
suitable construction of coin shutes, and one apparatus may be used to give change
for one, two or more different coins.
In order that the invention may be more clearly understood, reference is had to

page_text: is
A is the case of the apparatus of wood or metal, having fixed inside at the back
the sloping bar B. This bar carries the channels C in which the rolls of coins are
placed, a series of channels of varying sizes to suit the values of the coins being
fitted on the front of the bar B, by means of the supporting cheeks c.
The ends of
the channels are closed by the spring tongues D also fitted to the bar B on which
slide the spring pushers E passing between the tongues and the ends of the channels,
and underneath the guides d. Each of these pushers is furnished with a nose or
projection e a short distance above the channel, formed by stamping out a small
portion of the metal. The pushers (with one exception hereinafter described) are
carried by a sliding frame F to the upper ends of the vertical bars of which the
pushers are fitted. This frame is operated by the lever G pivoted to a support
fixed on the bar B, and connected to a hinged arm G₁ by a link g so that on
pulling down the lever from the outside, the arm G₁ is also pulled down a
corresponding distance. The lever G passes through a slot a in the front of the
case at the back of which is fitted an arrangement which prevents a wire or other
device being thrust through to operate the machine dishonestly. This arrangement
consists of two sliding plates a¹ a sliding vertically in suitable guides, the plate a¹
having a long slot, and as a perforation just sufficient for the lever to pass through.
A stop a³ prevents the plate a' falling below a certain point. The arrangement
such that the slot a is covered at any position of the lever by the plate a¹ and the
size of the back plate is such that the slot in a¹ is always covered. The two
sliding plates are used to give the desired result without taking up too much room,
as a single plate would require to be moved through too great a distance. To the
end of the arm G' is connected the vertical sliding rod H by a link g' so that on
lowering the arm the rod H is also lowered. This rod passes through a guiding
loop on the frame F but is not connected in any way to the latter, so that the
frame cannot be moved by operating the lever G unless other mechanism be brought
into action. The rod and lever are returned to their ordinary position by the
spring g² shown in chain lines in Fig. 2 and the frame F is raised by the springs fl.
This connecting mechanism is operated by the coin for which change is required.
The coin is passed through a slot in the front of the case and falls down a coin
shute J of irregular form provided with means for detecting bad or light coins.
The shute is shown clearly in Figs. 4 and 5, and carries at its lower end in suitable
bearings the lever K having a weight k at one end, the other end closing the open
bottom of the shute. This weight is adjusted so that if the coin be of the proper
weight, the lever will be overbalanced and allow the coin to fall through, while if
too light it will be retained and supported by the lever. The end j of the shute
is also open, but is normally closed by the small plate carried on the end of the
lever L. This lever at its other end bears against the side of the lever G,
which when in its ordinary raised position keeps the plate against the aperture
of the shute, but when it is lowered, the spring presses out the lever and opens
the aperture. Thus if a coin is not of the proper weight and is retained at the end
of the shute, on this plate being withdrawn it will fall out and on to the slanting
ledge M, sliding down into the front tray N, from which it can be removed through
the opening a in the front of the case. Light or bad coins are thus always
returned, and no change can be obtained.
The size of the shute and slot is of course such that no larger coin than the one
intended can be inserted. If the coin is of the proper size and weight and over-
balances the lever K, it falls down into a second sbute O forming a continuation
of J, and on to the end of a lever P. This lever is bent as shown in Figs. 1, 2, 6
and 7, and in its normal condition bears against the swinging arm Q pivoted to the
lower end of the frame F, and formed with a shoulder or projection q at its lower
end. When this arm is released it swings so that the projection is brought under
the cross piece h on the end of the rod H, as shown in Fig. 6, thus forming a
connection between the rod operated by the lever G and the sliding frame carrying
the pushers E. The lever F is limited in its motion by the stop on the frame F
so that the coin only partially opens the shute aperture and is prevented from

page_text: falling out until the frame is lowered and the stop movel out of the way of the
lever. The connection between the frame and the rod is thus retained until the
operation is completed.
Fig. 6, shows the coin partially opening the shute aperture and allowing the
necessary connection to be made, and Fig. 7 shows the frame being lowered, and
the coin just being released.
In the apparatus shown in the drawings, two shutes J are employed, one serving
for the reception of sovereigns and the other for half sovereigns. The channel C₁
in this arrangement supplied with half sovereigns and the apparatus is arranged
so that when a sovereign is inserted all the pushers E are operated on the pressing
down of the lever G and when a half sovereign is supplied all the pushers excepting
that ejecting half sovereigns come into action. To allow of this the vertical bar Fi
to which the pusher belonging to that channel is attached is not fitted to the bottom
bar of the frame, so that unless separately connected to the sliding bar H it will not
be actuated. The swinging arın Qis in this case fitted to the bar F¹ which is formed
with a small shoulder, so that though the frame F can be operated separately, it
is always pushed down along with the bar F. As shown in Fig. 7 the shoulder f³,
when the bar F is lowered engages with the frame F & actuates it.
The action of the apparatus is as follows:-The coin for which change is required
is dropped down the shute J falling on to the weighted lever K, which if the coin is
of the proper weight it overbalances, opening the aperture and falling into the
shute O. It then drops on the lever P and causes it to partially open, releasing
the swinging arm Q, the shoulder q thus projecting below the cross piece h. The
weight of the coin keeps the lever Q down and the aperture in the shute partially
opens the stop preventing the lever dropping too far. The lever G is then pressed
down lowering the rod H with the cross piece h. This engages with the swing
arm and pulls down the frame F carrying the pushers E, the projections e of
which catch on the edges of the lowest coins in their respective channels pushing
them down before them. The spring tongue D allows the coins to pass one atia
time until they slide past the bottom of the channels, when the tongues spring
back and prevent any others passing. The released coins fall on to the sloping
ledge M, a guide piece c¹ on the channels ensuring their, falling properly, and thence
into the receptacle N, from which they are removed at the front.
When the lever has reached the lower part of its stroke, the stop f² has been
drawn down sufficiently far to release the lever P, allowing the coin inserted to
fall through into the receptacle R placed at the back of the box, separate ones
being preferably employed for the different values of coins and their respective
shutes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
