Improvements in Coin-freed Machines.
I, HENRY JOHN DAVY, of 6, Christ Church Terrace, Christ Church Street,
Chelsea, Licensed Victualler, 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 has for its object to prevent the withdrawal of a coin from the
machine after it has been placed therein.
In the accompanying drawings Figures 1 and 2 show front and back views in
perspective and Fig. 3 a vertical section of the shoot of a coin freed machine
having my invention fitted thereto in an intermediate position. Figs. 4 and 5 are
similar views to Figs. 1 and 3, and show the apparatus fitted to the bottom of the
shoot. The remaining Figures 6, 7, 8, 9 shew detail views of various parts of my
improved mechanism:-Figs. 6 and 7 being views in front and end elevation
of the sleeve and guard with counterpoise, and Figs. 8 and 9 showing alternative
forms of such guard and counterpoise.
To carry out my invention I fit the coin shoot a, of the machine with a sleeve b,
pivotted whereto is a guard c, which may be of any convenient form; say, for
instance, either that of a blade, as shewn at Fig. 8; or of a fork, as shewn at
Fig. 9. Such guard is furnished with a counterpoise d, or its equivalent, whereby
it is automatically kept in position against the bottom of the sleeve, which is
preferably chamfered off to allow the guard to lie close against it.
When the sleeve is mounted on the shoot in an intermediate position a slit is
made in the back plate of the shoot, and such plate is bent outwards as shewn
at a', Figs. 1, and 2, while a slot is made in the front plate thereof so that the
guard can pass through and rest against the bottom of the sleeve in the manner
already described.
When however the sleeve is mounted on the bottom of the shoot, as shewn in
Figs. 4 and 5, this arrangement is unnecessary. Such sleeve may be secured
in position by screws e, as indicated in the drawings, or in any other convenient
manner.
The operation of my invention is as follows:-When a coin is placed in the
machine, it falls down the coin shoot, and in its descent depresses the guard c,
which after the coin has passed, automatically returns to its normal position by
the operation of the counterpoise d, or its equivalent, thus closing the shoot.
Assuming the coin is attached to a string with the object of again withdrawing
it from the machine, upon the operator pulling such string in order to do so;
the coin is brought in contact with the guard, thereby compressing the latter
tightly against the bottom of the sleeve and thus effectually preventing the
withdrawal of the coin, which upon the operator releasing the string falls back
into the machine.
If the guard is furnished with a knife edge, such knife edge severs the string, one
portion thereof falling into the machine with the coin, while the other portion
is left in the hand of the operator. The advantage of providing the guard with

page_text: a knife edge is, that by severing the string it obviates all risk of the shoot
becoming choked by reason of the string being entangled with the guard.
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:-
:―
In a coin freed machine an apparatus consisting of a sleeve having a suitable
guard furnished with a counterpoise or its equivalent pivotted thereto, which
guard automatically closes the coin shoot of the machine, thus effectually prevent-
ing the withdrawal of a coin therefrom, all substantially as hereinbefore described.
