Improvements in Coin-freed Electric Shock Machines.
I, GRAYDON POORE, of 9, Cowcross Street, in the County of London, Civil 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:
፡፡ penny-in-the-slot"
This invention relates to that class of so-called automatic or
machines by which an electrical shock can be administered to the user after the
insertion into the slot of a coin and operation of certain parts by the user and has for
its object the construction of a simple and reliable apparatus for the purpose.
A machine made according to this invention consists essentially of two parts in
combination, viz., a novel and efficient coin freed locking mechanism and the electric
A slot is provided in the casing
gear and the whole is enclosed in a locked casing.
and furnished with an internal shoot for directing the coin to a receiver hereinafter
described.
I will fully describe my invention in reference to the accompanying drawings, in
which Fig. I is an internal elevation and Fig. 2 a general front elevation. Fig. 3 is
a detail view of the coin lock mechanism in normal position and Figs. 4 and 5
illustrate successive changes of position during operation, and Fig. 6 a further detail
hereinafter explained. Similar reference letters indicate the same parts in all of
these figures.
A represents the casing in the upper part of which is the coin slot with suitable
mouth piece at a. Below the slot within the casing is a shoot $ for directing the coin
to an open bottomed receiver R hereinafter described; on each side of the machine a
rotary handle H H¹ is provided and the operator while receiving a shock holds one
of these in each hand. Referring to the coin mechanism, one of these handles H is
fixed to a spindle h rotatable in a long bearing ¹ and carrying at its inner end a
suitably counter-weighted cranked lever C the upper end of which forms the coin
receiver R above mentioned which normally underlies the foot of the coin shoot S.
To the outer end of a fixed arm or support E is pivotted a pawl P which normally
engages a notch r in or on the receiver R or equivalent part of the lever C as shown
in Figs. 1 and 3, thus preventing the latter moving and rendering the mechanism
inoperative.
The pawl has an inclined projection or tail p such as illustrated arranged in such
position and manner that when a coin has been inserted and fallen into the receiver R
as in Fig. 1 on rotation of the handle H the upper part of the coin X will pass under
the said tail p and raise the pawl P as in Fig. 4 out of its detent and thus allow the
cranked lever C to be turned to its full determined extent.
In order to prevent the coin passing through the open base of the receiver R before
the proper time a pair of fixed slides T T is provided just below the base over which
the coin must be moved with and in the receiver R before it can fall to the money
0 drawer (not shown), and these slides T T are just spaced sufficiently far apart to
allow of any coin of less diameter than that intended to fall through and be
inoperative.
When the cranked lever C has been turned through a sufficient distance to release

page_text: the coin, as illustrated in Fig. 5, a connection C¹ on it engages a fixed contact piece
such as G, Figs. 1, 3, 4 and 5 electrically connected between the battery K, and the
primary circuit of the induction coil I.
The handle H¹ is mounted on a spindle h² capable of rotation in a long bearing h³
and its inner end is connected to the core i of the said coil I in such manner as to
change the said core's position in the coil as the handle H' is turned to the right or
left and thus correspondingly increase or decrease the intensity of the electric shock.
This connection is made and the motion obtained by means of a cam F fixed on the
inner part of the spindle h² engaging a projection f depending from a lever L centred
at on the case, see Figs. 1 and 6, by which the latter may be raised to its extreme
position which is shown dotted. This lever L is connected to the core i by a connect-
ing rod in such manner as to raise and lower it in the coil I with the motion of
the handle H'. The electric connection between handles H, H¹, battery K, coil I and
circuit breaker K are all made in any convenient way.
To make the machine more complete I may also connect the lever L by the crank J
and connecting rod J¹ to an indicating device such as shown in Fig. 2 which is
adapted to indicate the comparative strength of the current flowing through the
handles H, H¹.
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:-
A coin-freed electric shock machine consisting in the combination of the novel coin-
freed locking mechanism constructed and arranged as above specified, with the
electric gear, the whole being enclosed in a casing provided with coin-slot and shoot,
operating handles and electric connections and with or without the indicating device
above referred to, all adapted to operate substantially as herein set forth in reference
to the figures.
