PROVISIONAL SPECIFICATION.
An Improved Machine for Giving Electric Shocks Automatically by
the Insertion of a Coin.
I, GEORGE BRYANT, of 30 Chester Street Kennington Lane, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an automatic machine for giving electric shocks
automatically when a coin is inserted therein, and by means of which machine,
the force of the electric current increases automatically.
According to this invention, in a suitable case provided with electro-magnets,
connected with a battery I fit an indicating dial and pointer, behind which is a
pulley, over which a cord or chain passes.
One end of this cord or chain is
attached to the core of a solenoid, and the other end to a weight, so that when
a coin is inserted in the machine, and is pressed upon, by pressing on the terminals,
it will close the electric circuit, by means of a suitable arrangement of mechanism.
The said weight on one end of the cord is caused to rise, and thus allow the core
to immediately descend through the solenoid, after which the aforesaid weight
will fall gradually (the pulley over which the cord or chain passes being controlled
by clock mechanism) and in so doing will draw up the core through the solenoid,
thus gradually increasing the power of the electric current automatically, during
which time the coin will drop into a receptacle placed in the machine to receive it.

An Improved Machine for Giving Electric Shocks Automatically by
the Insertion of a Coin.
I, GEORGE BRYANT, of 51 Cricketfield Road, Hackney Downs, London,
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
aad by the following statement :-
This invention relates to an automatic machine for giving electric shocks
automatically when a coin is inserted therein, and by means of which machine the
force of the electric current increases automatically.
According to this invention, in a suitable case provided with electro-magnets
connected with a battery, I fit an indicating dial and pointer, behind which is a
pulley, over which a cord, or chain, passes.
One end of this cord is attached to
the core of a solenoid, and the other end to a weight, so that when a coin is
inserted in the machine, and is pressed upon, by pressing on the terminals, it will
close the electric circuit by means of a suitable arrangement of mechanism. The
said weight on one end of the cord is caused to rise, and thus allow the core to
immediately descend through the solenoid, after which, the aforesaid weight will fall
gradually (the pulley over which the cord or chain passes being. controlled by

page_text: clock mechanism) and in so doing will draw up the core through the solenoid, thus
gradually increasing the power of the current automatically, during which time,
the coin will drop into a receptacle placed in the machine to receive it.
And in order that my invention may be fully understood, I proceed to describe
the same, reference being had to the accompanying drawings, and to the letters and
figures marked thereon, that is to say :-
"
a is a

dial, (which may be suitably divided) over which travels a pointer b, this pointer
being operated by clockwork mechanism. c is a double drum, or pulley, over
which cords, or chains, d, d' pass. e' is a pin in the drum c, the object of which
pin is to ensure the safe return of a contact lever hereinafter referred to, to its
original position and c² a pin for throwing the said lever on to a contact switch n.
At one end of the cord d, a core e is attached, and at the end of the cord d', a
weight, which is contained in a "bucket 9, and moves up and down with it.
his a solenoid, through which (in an upward direction) the core e passes, when
the weight descends into, and with, the "bucket" g, which is swung in bearings g',
on the end of a lever 93, the object of this being to always ensure that the
"bucket and weight shall be kept' in a vertical position. i,, represent, in
dotted lines, two hemi-spherical terminals, which are depressed by the person
placing his hands on them, when he desires to receive an electric shock. ), is a
suitable battery, and kan electro magnet. I is a contact lever, pivotted at /', its
travel from side to side being limited by the pins m, m'. n, is the metal contact
piece, through which, and the magnet k, the circuit is completed, when a pro-
jection o, on the contact lever 1, touches it.
"
Fig. 2 represents, in cross section, the mechanism for pressing on the coin
during its passage down a curved, and inclined shoot p. The two armed lever 4,
pivotted at q', presses on the coin, which rests against the end of the shoot p, and
also against a projection r, of the lever g², pivotted at r¹. 8, is a spring which
brings the lever q, back to its initial position, after the operator removes his hands
from the terminals, and s', a spring for ensuring the return of the lever g³, after
the coin has fallen into a receptacle, in the case of the machine. t, is a counter-
balance weight, on the other end of the lever g², and t¹, a contact spring, through
which the circuit is completed, when the lever g², returns to its original position.
Fig. 3 is a plan of the curved, and inclined shoot, along which the coin passes.
The coin is dropped into a longitudinal slot in the front of the machine (not
shewn in the drawings). In Figs. 2 and 3, similar letters refer to similar parts.
The machine acts as follows:-
:-
A coin is dropped into the slot in the front of the machine, and travels down
the curved and inclined shoot p, until it is stopped by the end of the said shoot.
The terminals i, i, are then pressed down, which action also depresses the two
armed lever g. As the coin is being depressed its edge presses against the pro-
jection of the lever 92, thereby raising the said lever, and with it the bucket
and weight f, which motion allows the core e, to which the cord d, is attached, to
descend through the solenoid h, thereby turning round the drum c, and with it the
pointer b, till the core e rests on the bottom of the case. The contact lever 1,
being now moved by the pin c², falls to the right, the projection o, touching the
contact piece n, thereby completing the circuit. As the weight and bucket
descend, the pointer b returns over the graduated dial a, and the core e ascends
through the solenoid h, the current increasing in intensity, the higher the core
ascends through the solenoid.
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 :-
The general construction, arrangement, and combination of the several parts,

insertion of a coin, whereby the strength of current is automatically increased,
substantially as shewn and described in the accompanying drawings.
