Electricity upon the Insertion of a Coin.
We HENRY CHARLES BRAUN and ARTHUR FORD LLOYD of 28 Clipstone Street
London W. Engineers, do hereby declare the nature of this invention to be as
follows:-
A chair or seat having metal arms handles or knobs, which are employed as
conductors of electricity, which electricity is generated by either a galvanic battery
or a magnetic apparatus contained in the space under the seat of, or at the back of
the said seat or chair.
On one or both of the metal arms of the chair we fit a sliding collar, which is
fixed to the sliding har in the inside of the tube which forms the arm of the
As the
chair, which sliding or running bar holds at its one extremity, the core.
collar is moved by the band either backward or forward, the core is slid in or out of
the coil, the strength of the electric current thus produced being registered on
a graduated scale attached to the arm, or recorded on a dial at the back of the
chair.
Where we employ knobs as conductors, we attach them to the sliding or running
bar which holds the core, in like manner. A slot for the reception of coin is placed
in a convenient position in the back of chair &c. or is made in one of the arms or
knobs from which slot the coin is conducted by a shoot or channel to act upon and
release a catch, and so allow a current of electricity to be taken.
When the electricity employed is obtained from a battery placed in the space at
back of chair or under seat of same it actuates a contact-breaker and is intensified
by means of an ordinary induction coil. When we use a permanent magnet with
revolving coils for generating electricity we arrange a falling rack attached to the
seat which ruck cogs in the pinion of spindle in connection with the before mentioned
coils. As soon. as a current has been received and the person has left the chair,
the seat returns to its former position being raised by counterweights.
Dated this Eighth day of February 1888.

Electricity upon the Insertion of a Coin.
We HENRY CHARLES BRAUN and ARTHUR FORD-LLOYD of 28 Clipstone Street
London W. Engineers 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 :-
A chair or scat having metal arms, handles or knobs which are employed as
conductors of electricity generated by means of either a galvanic battery or by a
magnetic apparatus contained in the space under the sent of, or at the back of
the said chair. On one or both arms of the chair or seat we fit a sliding_collar
or knob A which is attached to the sliding bar or rod which holds the core D As
the collar or kuob is moved either backwards or forward the core is elid in or out
of the coil E, the strength of the current of Electricity thus produced boing
registered on a graduated scale attached to the arm or recorded on a dial at back
of chair.
A slot for the reception of coin is placed in a convenient position in the back
of chair or is made in one of the arms or knobs J. From this slot the coin is
conducted by a chute or channel K so as to act upon and release a catch and so
allow a current of electricity to be taken from the electrodes. Where the electricity
employed is obtained from a battery placed in the back of chair or under seat of
same it actuates a contact-breaker and is intensified by means of an ordinary
induction coil. When we uso permanent magnets with revolving coils for generating
electricity we arrange a falling rack attached to the seat which rack cogs in with
and rotates the before-mentioned coils. As soon as a current is received and the
person has left the chair the seat returns to its former position being raised by a
counterweight.
To this chair of special construction wo affix two arms of brass or other metal
such arms being formed preferably of hollow tubes fitting into the frame of the
back of the chair and terminating by knobs or other decorative ornaments in the front.
On one or both of these metal tubes B we place collars to slide up the length or part
of the length of the said tubes A. Attached to the inside of these collars is a rod C
carrying on one end a soft iron core D which core slides into an ordinary induction
coil E fitted into the end of the metal tube or arm, when the collar is drawn back by
a person pulling it with the hand. The primary wires are connected through an
ordinary contact-breaker with a galvanic battery in the seat of the chair or at the
back thereof. The other wire from the primary goes to the contact inaker of a clock-
work movement placed in such manner that when a coin falls down the chute situated
in the back of the chair or on the knob of one of the arms J a lever is actuated which
releases a catch and allows the clockwork to work for a given number of seconds
during which time it forms contact by the connection from the primary coil rubbing

page_text: against that from the battery, and after which the contact is again broken. The
secondary wires of the coil go one to each arm thus forming them into electrodes
or conductors of olectricity to the person who holds them or the knobs before-
mentioned.
When a penny has been placed in the slot or aperture it falls down the chute K on
to the lever which sets up a current which passes through the primary wire of the
induction coil thence through the socondary to the arms B. To increase the current
it is necessary to take hold of the collar A which slides on the tube B containing the
coil E thus strengthening the induced current in the electrodes.
Upon the tube B which holds the coil is a graduated scale engraved or affixed
which scale is made visible by the removal or partial removal of the collar A allowing
the space underneath the same to be seen, thus denoting the strength of the current
taken.
We also place a small dial in the upper part of the back of the chair with a
pulley over which runs a chain attached to the rod which is fixed to the collar, in such
manner that when the collar A is pulled back the hand of the dial is turned to show

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. We claim the right of employing a seat or chair as a means of administering a
current of electricity through the medium of metal tubes &c. in the place of arms
whether such current be generated by a galvanic battery or a magnetic or an electro-
dynamic machine.
2. The use of a seat or chair for the purpose of an Electro medical automatic
battery in which the current is set up by means of a coin-freed attachment actuated
by the falling of a coin down a chute.
3. In a mechanical seat or chair the employment of metal handles arms or knobs
as conductors of the electrical current of a battery or dynamic machine.

page_text: 4. We claim the right of using as arms metal tubes in which are fixed induction
coils and upon which tubes are sliding collars knobs or handles attached to the core
and which by a backward or forward movement forces the core into the coil thus
intensifying the current.
5. We claim the employment of a clockwork rogulator in connection with
mechanical electrical chairs so that a coin falling on a lever releases a catch and allows
of a revolution or partial revolution of a wheel upon which contact is made thus
setting up a current during a given and predetermined period.
6. We claim the combination of an automatic electro medical battery and a chair
in which the arms of the chair or part thereof act as conductors of electricity to the
person seated therein, substantially as herein described and set forth.
