Improvements in Machines for Giving Currents of Electricity on the
Insertion of a Coin, Token, or the like.
1, PERCIVAL EVERITT, of No. 47, Cannon Street, in the City of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
In order to carry out my present improvements I construct ny machine with a
suitable case containing a galvanic, a primary, or a secondary battery, accumulator,
or the like with or without an induction coil and capable of giving a current which
can be transmitted to handles.
In order to cause the current to be transmitted to a pair of handles, a connection is
made between the handles and the generator used; one handle can be permanently
connected whilst the other is connected only on the insertion of a coin, token, or
the like.
In order to effect this, I use a lever slide or the like connected to a wire from the
generator, and on the insertion of a coin, the lever slide or the like falls slightly,
and by pressure or its weight, makes a contact with a wire connected to the handle.
The lever slide or the like, is still allowed to fall and after having fallen a certain
distance, the coin, token, or the like slides off, so that the lever can then return.
•
In order to allow the lever to fall slowly, it is retarded by a dash pot, fan or
pendulum, or other well known retarding mechanism; or in some cases is allowed to
fall quickly and on discharging its coin, is retarded by similar means on returning,
so that the current can be given for a given time, depending on the retarding
mechanism.
I also cause one or more of the handles to be connected to any well known device,
for increasing or decreasing the strength of the current, so that on being moved it
will cause a variation in the strength of the current. At the same time there is
connected to this handle a suitable dial or other indicator so as to indicate the strength
of the current.

Insertion of a Coin, Token, or the like.
I, PERCIVAL EVERITT, of No. 47, Cannon Street, in the city of London, 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-
In order to carry out my present improvements I construct my machine with a
suitable case containing a galvanic, a primary or a secondary battery, accumulator or
the like with or without an induction coil and capable of giving a current which can
be transmitted to handles.
;
In order to cause the current to be transmitted to a pair of handles, a connection is
made between the handles and the generator used; one handle can be permanently
connected whilst the other is connected only on the insertion of a coin, token, or
the like.
In order to effect this I use a lever, slide or the like connected to a wire from the
generator, and on the insertion of a coin, the lever, slide or the like falls slightly and
by pressure, or its weight, makes a contact with a wire connected to the handle.
The lever, slide or the like is still allowed to descend and after having descended
a certain distance, the coin, token or the like slides off so that the lever can then
return.
In order to allow the lever to descend slowly, it is retarded by a dash pot, fan or
pendulum, or other well known retarding mechanism; or in some cases is allowed to
fall quickly and on discharging its coin, is retarded by similar means on returning
so that the current can be given for a given time, depending on the retarding.
mechanism.
I also cause one or more of the handles to be connected to any well known device
for increasing or decreasing the strength of the current, so that on being moved it
will cause a variation in the strength of the current. At the same time there is
connected to this handle a suitable dial or other indicator so as to indicate the strength
of the current.
In order to enable my invention to-be fully understood I will proceed to describe
how it can be carried into practice by reference to the accompanying drawing.in
which
Figure 1 is a front elevation of a machine.constructed according to my invention
for giving currents of electricity on the insertion of a coin, token or the like.
Figure 2 is a longitudinal section of the same on line A B of figure 1 and
Figure 3 is a plan of the machine with the top of the case removed to shew the
mechanism.
Similar letters in all the figures indicate similar parts.
a is the lever having a weight a' at one end and connected by the wire 6 through
the primary coil e and contact maker d¹to one pole of the battery or generator of

page_text: electricity c¹ in the following manner. The wire as it comes from the lever a is
wound around the coil and back to the end of the coil from which it started; it then
passes to the contact maker d' and thence to the battery c'.-The lever a turns on a
pivot d insulated therefrom and carries a plate e at its forward end to receive the coin
which is introduced through the money slit f

and h are the handles of the machine the handle / being arranged so that it can
be drawn forwards.
i is the wire connected at one end through the electro magnet j and wire k to the
moveable handle h. The other end of the wire i is connected to the pivot d on which
a lever works and with which it is in electrical communication.
The fixed handle g is connected to the other pole of the battery c¹ by a wire n.
When a coin is inserted in the apparatus its weight will cause the lever a to descend
and in descending the said lever comes against a pin m on the lever whereby an
electrical connection is set up between the wires b and i and a current of electricity
will be communicated to a person holding the handles 9, h.
When the lever a has descended a certain distance as indicated by the dotted lines
in Figure 2 the coin, token or the like will slide off into a money till o and the lever a
will then return to the position shewn in full lines in figure 2 in which position it no
longers forms an electrical connection between the wires b and i and the current of
electricity is therefore interrupted.
p is a stop which prevents the lever from following the lever a beyond a certain
point when the latter lever is ascending.
The lever advantageously carries a spring pawl y engaging with a ratchet wheel »
attached to a toothed wheel connected with an escapement, whereby the descent
of the lever a is retarded so that the electric current can be communicated for a
given time. Or other suitable means can be provided for retarding the movement of
the said lever.
The sliding handle h is connected to a device for increasing or decreasing the
strength of the current which device can advantageously consist of a regulator in
the battery coil c so that on the said handle being drawn outwards it will cause the
strength of the current to be increased.

by a
is the indicator moving over a dial w and connected to the sliding handle
cord passing over pulleys y and, the pulley being fixed to the arbor of the
indicator v. By this means the indicator is moved as the handle h is drawn out and
the strength of the current is thereby indicated on the dial w.
e is a catch forming the armature of the magnet j. This catch engages in a notch
in the sliding handle h as shewn in Figure 2 thereby preventing the handle from
being drawn out so long as the electric circuit is not completed by the application of
a coin, token or the like. As soon however as the circuit is completed the magnet
attracts the armature or catch and the handle is thereby unlocked.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The combination of parts forming the improved machine for giving currents of
electricity on the insertion of a coin, token or the like as herein before described and
illustrated in the accompanying drawings.
