WILLIAM SAMUEL OLIVER, Albert House, St. Pauls Road, Canonbury, N.
Engineer, do hereby declare the nature of my invention for AN IMPROVED MACHINE
FOR AUTOMATICALLY ADMINISTRATING AN ELECTRIC CURRENT to be as follows :-
On dropping a coin of prearranged size into the apparatus, it is possible to depress
a platform or release a weight or move a portion of the machine, this may be also
automatically effected by the same or another coin. By either of these motions or
several of them conjointly, motion is communicated by any usual mechanical device
to a small dynamo, & the current thus produced is conveyed to two handles which are
grasped by the operator. It will be possible to vary the strength of the current by
means of a rheostat or other device which may be worked automatically or by
movement of the handles or handle or portion of handles or other device such as a
pedal, fly wheel or screw. The same variation of current may be produced by the
introduction of a shunt or other method of introducing known resistances into the
circuit. I also use the current to work the electric light ring a bell or show an
advertisement, or any other method of attracting public notice.

I WILLIAM SAMUEL OLIVER of Albert House, St. Pauls Road, Canonbury, N.
do hereby declare the nature of my said invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of this invention is an improved machine for automatically administering
an electric current.
For the purpose of this invention I drop a coin of pre arranged size into the
apparatus by the slot a shown on the annexed drawing and it is then possible to
depress a platform a', say by a person standing thereon or it may be by moving a
portion of the machine.
The coin falls to the bottom of the tube b and depresses and releases the lever
catel e. this allows the rack d to rotate the gear wheels e and by this the gear
wheels ff. either directly or otherwise. By these means or by any usual mechanical
devices, motion is communicated to a small magneto dynamic machine hand the
current thus produced is conveyed to two handles g. 9. which are grasped by the
operator.
The strength of the current may be varied by a reheostat or other device for
altering resistance which may be worked in any well known manner.
The current is used to work or ring a trembling bell i or it may be to show an
advertisement or any other method of attracting public notice.
jis a counterbalance weight to return the platform and to readjust the mechanism.
The tube is composed of two side rails with a slot between on the underside so
that should a coin smaller than say a penny be inserted into the mouth a it will fall
through the slot on to the deflecting plate k and thence into the receptacle or till
without operating the catch c.
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 improved machine for automatically administering an electric current to a
person standing on the platform or other portion of the machine, said machine
being rendered workable by the dropping in of a coin as hereinbefore described.
