PROVISIONAL SPECIFICATION.
Improvements in the Application of Electricity to the Human Head.
JOHN STEVENSON of Norwood Lodge, Middlesbrough in the County of York,
Merchant do hereby declare the nature of this invention to be as follows:-
My invention consists in the application of flexible wire gauze as a conductor of
electricity to the skin, the requisite electricity being generated by means of a dry
pile or other small battery giving a feeble current. The wire gauze is by preference
gilded so as always to preserve a bright metallic surface & it is applied in two or
more sections so insulated as to secure the passage of the current through the
integuments of the head as is well understood. The sections are attached to any
suitable material forming a cap for the head.

COMPLETE SPECIFICATION.
Improvements in the Application of Electricity to the Human Head.
I, JOHN STEVENSON of Norwood Lodge, Middlesbrough, Merchant, 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:
My invention consists in the application of flexible wire gauze as a conductor of
electricity to the skin, the requisite electricity being generated by means of a dry
pile or other small battery giving a feeble current. The wire gauze is by preference
gilded so as always to preserve a bright metallic surface, and it is applied in two or
more sections so insulated as to secure the passage of the current through the
integuments of the head, as is well understood. The sections are attached to any
suitable material forming a cap for the head.
In the accompanying drawings,
Fig. 1 shows a vertical central section; and
Fig. 2 a plan of a cap for the head having my invention applied thereto.
In
1, 1ª are pieces of gilded wire gauze; they are secured to the inside of the
cap or head covering 2 by any suitable means, such as by sewing, and they form
the terminals of a dry cell, secured in the example shown to the crown of the
cap (outside) by a piece of woven fabric 3 sewn to the cap. The dry pile or
cell may be of any suitable construction capable of giving a feeble current.
the example shown it comprises a box 4 formed of zinc fitted with a carbon plate 5
which is bedded against a layer 6 of a mixture of powdered carbon and peroxide of
manganese, the space between this layer and the zinc box being filled with a layer 7
of suitable moist exciting material such as a mixture of ammonic chloride and a
deliquescent substance such as calcic chloride, the whole forming a cell adapted to
The
act after the manner of a Leclanche cell to produce a weak electric current.
carbon plate 5 and the two layers 6 and 7 of material are retained within the box 4
by an outer layer 8 of material such as pitch formed with a hole 9 by which gas
liberated at the carbon plate can escape and by which air can enter the layer 6 of
material to regenerate the same as well understood. The zinc box 4 and carbon
plate 5 are connected to the pieces 1, 1 of wire gauze by conductors 10 and 11
respectively and when the cap is worn the circuit is closed through the wearer's
head.
As will be obvious my invention can be applied to caps or head coverings of
27

page_text: various kinds and shapes and formed of material that is a bad conductor of electricity
so as to insulate the pieces of wire gauze from each other.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
In the application of electricity to the human head the use in the manner herein-
above described of wire gauze applied to a cap or head covering and electrically
connected to the poles of a dry pile or cell adapted to produce a feeble current as
set forth.
