Improvements in Coin-freed Apparatus.
I, CHARLES BRADBURY, of No. 37 Torrens Road, Brixton, in the County of Surrey,
Agent, 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 apparatus such that on the introduction of a coin,
mechanism is automatically set in motion and is maintained in motion for a
predetermined time for performing various operations such as delivering packets
of goods or quantities of liquid as will be described with reference to the accompanying
drawings.
Figures 1, 3, 5 and 6 are side views, Fig. 2 is an end view and Fig. 4 is a plan of
motor apparatus according to this invention; Figs. 7 and 8 are detached side views
shewing the levers acted on by a coin. The other figures represent modifications and
details hereinafter referred to.
On a spindle is centred loose a drum t on which is wound a cord chain or rope Q
loaded by the driving weight. A ratchet wheel z fixed on the spindle is engaged by
a pawl pivotted on the barrel t so that as the weight descends the barrel turns the
spindle in the one direction, but the barrel can be turned in the opposite direction to
wind up the weight without turning i. There is also fixed on the spindle ia wheel a
having teeth of ratchet form that act on one arm p of a lever pivotted at n, the other
arm q of which engages a stud on a vertical bar B. The upward movement of this
bar caused by the action of a tooth of a may be utilised for various purposes as for
instance pushing out a packet or opening a valve for issue of liquid and holding it
open during the time occupied by the tooth in passing p. Teeth of various lengths
may be employed to suit various predetermined periods. By toothed gear b c d e the
rotation of i is cominunicated to a volute disc having a drop at 1. On the edge of
this disc rests a stud projecting from a lever rur, which is pivotted at u and carries
a counterweight o'. When this lever is in the position shewn in Fig. S its stud by
engaging the drop stops the disc and consequently prevents the mechanism from

moving. When the end of the lever is depressed as shewn in Fig. bythetweight
of a coin G which has descended the shoot A, the disc f is free to revolve until it is
again stopped by the stud of the lever.
As the speed off due to the multiplying gear is considerable, the strain at is
proportionally small. In order that the disc f may make several revolutions before
it is stopped, the end of the lever is kept down as shewn in Fig. 7 by an arm
resting on the circular part 3 of a cam g and it cannot ascend until the flattened part m
extending from 1 to 2 presents itself to as shewn in Fig. 8. This cam g being
driven at any desired relative speed from the general gearing the time during which
the disc remains free to revolve may be determined as desired.
Another lever ses pivotted at supports when depressed by the coin G so as to
retain G in position for a time visible and prevent from rising too soon. The
flattened part of the cam g serves to release first the levers vs to discharge the
coin and then to release the lever to stop the machine. Instead of employing
a weight to drive the mechanism a spring in a barrel may be used as shewn in
the side view Fig. 9 and plan Fig. 10. The winding up of the weight or spring
is effected by applying a key to the squared end of a spindle wo which is connected
by gearing to the barrel.

In order to moderate and vary the speed of the mechanism a spindle i² rapidly
driven carries a flyer having two blades y y" which can be set more or less obliquely
to the direction of their revolution. In Figs. 9, 10 and in 11 and 12 are shewn
means of closing the slot for introduction of the coin when the clockwork is run down.
As shown in Figs. 9 and 10 a spindle T" driven by gearing from the barrel has a
crank arm which in one part of its revolution moves an arm U⚫ to cover the
opening..
As shewn in Fig. 12 a stud t¹ on the drum t first acts on a projection II of a
pendant lever and raises it so that a shoulder III of the lever rests on a stationary
stud. When t¹ makes another revolution it now acts on a shoulder at I and
thus through the link U¹ moves the lever U so that its bent end crosses and
obstructs the coin passage A.
When a weight is employed it acts as shewn in Fig. 11 pressing down a
spring arm S connected with the lever U by a cord T. The mechanism
described as being applied to move up a rod B and hold it up for a determined
time might obviously be applied to produce other mechanical movements with
periods of rest. The movement of the rod B may be utilised for opening a
valve as shewn in Fig. 13. The valve seat D is fixed at the bottom of a cistern C
and the valve D' is arranged within a case E having an opening, at El; for the
upper end of B. When the rod B is raised the valve D' is opened allowing¡liquid
.to issue at F..
When it is intended that several coins should be introduced in order to start the
apparatus the coin duct may be arranged as shewn. in side view at Figs. 14 and 15,
face view at Fig. 16 and plan at Fig. 17.
The duct has two mouths K. and L both obstructed by levers M and N crossing
them, or two branches M and. No of one lever. There is a side slot a ẞ above the
mouth L. The first coin introduced descends to O and rests on M. The next coin P
rolls over through the slot a ẞ into L and rests in the position F on N. The
weight of the two coins now. acting depresses M and N starting the clock work,
whereon the coins can fall off. as indicated in Fig. 15. The mouth K may, be made
.deeper to contain several coins.
Also by introducing a cross.peg R the mouth K. may be shut off altogether.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is; to be performed, I declare that what I
claim is
1. The construction and use of a. clock work motor worked by a weight when freed
by the action of a coin, substantially as described with reference to Figs. 1 to 8

page_text: 2. The modified construction of motor worked by a spring, substantially as described
with reference to Figs. 9 and 10.
3. In a motor of the kind referred to in the preceding clains, the combination of
the toothed wheel a the lever pn q and the guided rod B, substantially as described
with reference to Fig. 6.
4. The combination of the disc f the cam 9 and the levers rur¹ and s v s²,
substantially as described with reference to Figs. 7 and 8.
5. The construction and arrangement of the coin duct for operating with several
coins successively introduced, substantially as described with reference to Figs. 14 to 17.
Dated this 14th day of February 1889.
