PROVISIONAL SPECIFICATION.
Improved Construction of Plates and Arrangement of Fastenings
for Connecting them in Voltaic Order for Medico Electric
Purposes.
I WILLIAM GEORGE JOHNSON of The Medico Electric Belt, Truss and Battery
Company Limited, 58 New Bond Street, Middlesex Electrician do hereby declare the
nature of my said invention to be as follows:-
This invention relates to a certain novel construction of plates for making the
elements of Medico Electric bands also in means of connecting said elements in
Voltaic order to any desired length according to the purposes for which said band is
intended or the position it has to occupy upon the body.
One plate of each element, say the copper, is formed with rectangular or other
shaped openings in the surface or surfaces and with cut through indented portions to
form lugs or ears from either the faces or ends for articulating them to the opposite
pole plate of the other clement, or by lacings of cat-gut or cord, in which case the
ears or lugs would form the means of attachment through spiral or other wires so
that each element has a freedom of action to and fro, also a twisting about to allow
any part of the band to adapt itself to any part of the body to which it may
be applied.
The terminals may be of disc or other shape and the cords, if cords be used, secured
in or run through stamped indents forming loops, ears or lugs between which the cord
can be clamped to fix it in position. .
The plates with the rectangular or other shaped openings have enclosed within
their folded portions the opposite pole plates of the element, these being protected by
wrapped or laced thread.
Any method or appliance can be used for fixing the plates or bands to the body
or limb of a person and the band may be partly enclosed in a fabric by means of
which the electrical power generated may be concentrated to the exposed pole plates
which alone may touch the person.

Purposes.
I WILLIAM GEORGE JOHNSON of The Medico Electric Belt, Truss and Battery
Company Limited, 58 New Bond Street, Middlesex, Electrician, 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:-
This invention relates to a certain novel construction of plates for making the
elements of Medico Electric bands also in means of connecting said elements in
voltaic order to any desired length according to the purpose for which said band is
intended or the position it has to occupy upon the body.
One plate of each element, say the copper, is formed with rectangular or other
shaped openings in the surface or surfaces and with cut through indented portions to
form lugs or ears from either the faces or ends for articulating them to the opposite
pole plate of the other element or by lacings of cat gut or cord in which case
the ears or lugs form the means of attachment. Spiral or other wires connect each
element so that they have a freedom of action to and fro, also a twisting about to
allow any part of the band to adapt itself to any part of the body to which it may
be applied.
The terminals may be of disc or other shape and the cords, if cords be used,
secured in or run through stamped indents forming loops, ears or lugs between which
the cord can be clamped to fix it in position.
The plates with the rectangular or other shaped openings have enclosed within
their folded portions the opposite pole plates of the element, these being protected by
wrapped or laced thread.
Any method or appliance can be used for fixing the plates or bands to the body or
limb of a person and the band may be partly enclosed in a fabric by means of
which the electrical power generated may be concentrated to the exposed pole plates
which alone may touch the person.
My invention is exemplified on the annexed drawings in which at Figure 1 I show
a plate of copper A with rectangular slots in two parts of it and with lugs B, B,
having indents C. C. through which a cord or cat gut or other flexible material D
can be run and clamped as represented in Figure 2 which shows a series of elements
made up from a number of said plates A folded and holding between the folded sides
the other plate E, a sample of which is seen at Figure 3, Figure 4 being a view of
the same pole plate with the protecting threads laced through holes at the edge to
prevent the two plates forming the element touching each other.
The plate Figure 1 has two slits F forming a lug or ear for the connection of a
copper wire G thereto, this being in connection with the ear H of the other pole
plate E which car projects beyond and clear of the copper folded plate A but so
arranged that at whatever position the elements are placed when made up in band
form they are always kept in voltaic order for the perfect flow of the current when
the elements are excited.
The cords D, D, are connected to terminal plates I. J, which have lugs formed by
stamping said plates through which the cord is laced and clamped; one plate I is
connected to the zinc E by the coiled copper connection G and the other or opposite

page_text: terminal by the copper coil of the copper plate A at the opposite end of the chain or
band. These terminals I. J, have holes in them for the connection of tape to fix them
to any part of the person.
If the plates of the band Figure 2 be exposed as indicated each element plays its
own part for distributing the current but if said band be covered by a fabric the
terminals alone are applied to the part of the person affected in a concentrated form
or what is termed a current of intensity.
Figure 5 represents a modified copper plate A in which the cords D may be
dispensed with and yet be connected to the pole plate of the adjoining element as
represented in the example Figure G where two elements are joined. This method of
connection is by constructing the copper plate A with two projections K and the zinc
element with two projections L, these being somewhat larger and slotted for the
projection K to be passed into and curled round in hook form for linking the copper
of one element to the zinc of the other the projections L, L, being first passed through
slots of the copper plate as shown.
The copper plates are flat and instead of being folded vertically as indicated in
the Figures already referred to they may be folded horizontally as at Figure 7 and
instead of the zinc of each element being coated or have thread wrapped upon them,
the flat copper plate may be so coated as to protect it from the zinc, the fold over
portions being compressed for clamping the cords D, whereby the chain or band is of
a flexible character as described with reference to Figure 2.
The copper plates which are flat may be composed of what is known as ribbon
copper and this ribbon may be folded as indicated after being coated or protected by
a thread so that the zinc, which may be of flat or round form, is arranged between
each fold of the copper and according to the sizes of each element so the number of
folds would be increased or diminisheil to correspond, their connection in voltaic order
being secured by compression at the joints as will be understood.
I have not shown a complete band in Figure 7, but terminals of any desired
shape, similar to I. J, can be voltaicly connected for making up a band of any
desired length.
The rectangular slots or spaces in the copper plates or between the copper and the
zinc admits of the desired depolarization.
I have referred to rectangular slots in the plate A but other shapes of slots or
apertures may be readily formed by stamping to permit of the free entrance of the
exciting fluid to the threads whether the band or chain be covered with flannel or
other porous material or the elements are left exposed.
I am aware that copper and zinc plates have been stamped and arranged as
elements and connected in voltaic order, the exciting fluid having free access to
threads, laced or covered, which also prevent the touching of the two plates forming
the element and I am also aware that elements have connected by flexible cords
therefore I make no claim to the combination of such plates and cords in a general
or broad sense but
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 particular construction or formation of copper and zinc plates shown on the
annexed drawings and the method or methods of connecting them voltaicly to produce
a chain or band for Medico Electric purposes as set forth.
