Improvements in Coin-freed Machines.
JAMES GILBERT CUMMING 88 Polwarth Gardens, Edinburgh Mechanical and
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the supplying to a person an electric shock after
a suitable determined coin has been first inserted in an opening provided in the
machine, and the electric circuit completed.
My invention consists in an inclined shute, at the lower end of which a mechanical
arrangement is provided for the secureing or releaseing of a spindle by the action
of a coin.
The coin after being inserted in the opening slides or falls down the shute till it
reaches a gauge slightly less than the diameter of the suitable determined coin.
The coin rests on one side against a fixed piece of metal, and on the other side,
against a spring or weighted pawl or lever.
When the spindle is turned, the coin prevents the pawl or lever falling into a
catch attached to the spindle, but when the spindle is turned farther round, one end
of the pawl or lever is raised and the other end releases the coin and allows it to
drop into a box, which is provided to receive the coin.
When the spindle is released it returns to its normal position, through being
attached to a spring. The pawl or lever falls into the catch on the spindle, if it is
attempted to be turned before another coin has been inserted in the machine.
I also provide along with the above arrangement an induction coil, two handles,
three contact makers, and an electric battery, which work in combination with a
number of balls, placed on inclined groved rails.
When a suitable coin has been inserted in the machine, and both handles held by
the person who wishes to receive the electric shock, one of the handles must be
turned round to put on the current and also to increase the power of the shock.
In doing so, the coin and a ball is released, and the electric circuit completed.
The ball rolls down inclined rails which are constructed, so that the ball rolls
for a length of time, till it falls onto a contact maker, which causes another contact
maker to be released, and the circuit broken.
Should the person release the handles before the ball falis on to the contact
maker-it will return to its normal position and break the circuit at the same
time.

COMPLETE SPECIFICATION.
Improvements in Coin-freed Machines.
I, JAMES GILBERT CUMMING of 88 Polwarth Gardens, Edinburgh, Mechanical
and Electrical Engineer, 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 which relates to improvements in coin-freed machines has for its
object to provide a machine whereby a person may be supplied with an electric
shock after a suitable pre-arranged coin has been inserted in the slot of the machine
and the electric circuit completed.
In order that my said invention may be more readily understood and easily

page_text: carried into effect, I will proceed to describe the same with reference to the accom-
panying drawings,
Figure 1 of which is a front view,
Figure 2, a transverse section, and Figure 3, a front view, with front removed, of
my improved machine.
Figures 4 and 5 are elevation and plan on an enlarged, scale of my coin freeing or
actuating mechanism.
Referring to the said drawings I construct a casing A, which may be made of
either iron or wood and provided with suitable doors a and standing platform a
Inside the said case A, and at the back of the coin slot a², I form an inclined
shoot B, which leads or conducts the coin to the mechanical actuating arrangement
which by the action of the coin releases the operating spindle C. The said
actuating arrangement consists of a gauge slightly less than the diameter of the
pre-arranged coin, the said gauge being formed by a projection on the one side b
of the shoot, and by the tail end d of a pivotted weighted lever or pawl D, which
is provided with a projection d'. A spring d is provided on the shoot B, to assist
in guiding the coin to the position in the shoot as shown in Figures 4 and 5; the
coin rests in this position until the spindle C has been partly turned by the operator
and owing to it having a suitably shaped catch or lock E (as shown more
particularly in Figures 4 and 5) mounted thercon raises the end of the pawl D
and so frees the coin which then drops down into a money-box or drawer F provided
in said case A. On the said spindle C being released by the operator releasing the
handle G, provided at front end of said spindle C, in front of the case A, the catch
or lock E returns to its normal position by means of the spiral or other spring H,
(more particularly shown in Figure 3) the one end of which is secured to a
drum J provided on said spindle C, and its other to the case A. The said normal
position of said lock E, as shown more particularly in Figures 4 and 5, is such
that if the spindle should be attempted to be turned without inserting a coin the
end d² of the pawl D would fall and engage with the recessed part e of the catch
or lock, thus preventing the machine from acting, the said pawl D being assisted
in its falling by means of the spring d³.
Inside the said case A. I also provide in combination with the foregoing an
electric battery K, an induction coil L, an electro magnet M, and three contact
makers N, P, and R, as also two handles G and S outside the case A, the latter
of which is stationary, the whole of the foregoing being insulated from the iron
case A. and suitably connected to each other by wires T in such a manner as to
give the necessary shock when the circuit is completed, the said circuit being com-
pleted by the operator turning the handle or knob G, thus causing the pin e² on the
lock E to free the top end of the contact maker P, which is carried on a centre P²,
and also provided with a spring P³, when turning on its centre the lower end of
the contact maker P, moves against a raised piece of metal on the spring P¹, and
at the same time a cam c¹ on the lock E moves against the spring contact maker N
and the circuit completed for the induction coil L. Grooved rails U are provided
at the back of the case A, the said rails U being arranged in a zig-zag fashion
down the back of said case A, and so formed as to act in combination with the
catch or lock E, which is the means whereby one ball or bullet is transferred
from the upper storage set of rails U₁ into the top end of the lower set, by
means of a ball entering into the hollowed out portion e¹ of the lock E, which
on being turned round carries the ball with it and so allows it to roll down the
inclined passage V, provided in the case, on to the top end u of the rails U.
The ball on being released rolls down the said rails, which are so arranged as
to permit of the ball rolling for a length of time before it falls onto the contact
maker R, which completes the circuit with an electro magnet M, causing it to
attract an armature on the lower part of the spring P¹, thereby releasing the
contact maker P, and thus breaking the circuit with the induction coil L.
The whole machine is such that on a person standing on the platform a', and
inserting a pre-arranged coin in the slot a², he then grasps both handles, G and S,

page_text: and begins turning the handle G to the right so as to cause the current being put
on by means of the contact makers N and P, and also to increase the power of the
shock by means of the regulator of the induction coil L being attached by a cord
to the drum J on spindle C, at the same time the lock E releases both a ball and
the coin. Should the person release the handles G and S before the ball reaches
the contact maker R, the spindle C would be returned to its normal position and
so cause the pin e² on the lock E to move against the contact maker P, and break
the circuit with the induction coil L. At the same time the ball would roll on
and fall on to the contact maker R as usual, after which it would drop into the
receiving box W provided for same. The whole forming an electrical machine in
which the duration of the shock is timed or only lasts during the travel of a ball
from the lock E to the contact maker R.
The handle G may be provided with an indicating scale g, and pointer y¹ so as to
show results.
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
1st. The general arrangement, construction and combination of the various parts
constituting my improved electric shock machine, all substantially, as and for the
purposes hereinbefore described and shown in the accompanying drawings.
2nd. In coin freed electric shock machines the arrangement and combination
therewith of my improved mechanical coin freeing or actuating arrangement, all
substantially as and for the purposes herein before described and shown in the
accompanying drawings.
3rd. In coin freed clectric shock machines the arrangement of the inclined
rails and balls, and parts in connection therewith whereby the length of duration
of the shock is measured, all substantially as and for the purposes hereinbefore
described.
4th. The general arrangement and combination of the contact makers N, P
and R, and electro magnet M, whereby on a ball or bullet reaching the lower
contact maker R, the circuit is broken, all substantially as hercinbefore described
and shown in the accompanying drawings.
