PROVISIONAL SPECIFICATION.
Improvements in or relating to Electro-medical Belts and
Appliances.
I, ALEXANDER KNOX of 85 St. James Road, Upper Tooting S.W. London,
Tutor, do hereby declare the nature of this invention to be as follows:—
This invention relates to the electrodes or plates of metal used in electro-medical
belts or other wearing appliances which are intended to produce and impart
currents of electricity to the person of the wearers, and also to the method of
fixing such electrodes onto or in the belt or backing material which forms the body
of the belt or wearing appliance.
According to this invention the electrodes which are usually circular disks are
made with a domed shank or depression in their centre or otherwise in which are
made two holes for the passage of the connecting wire.
Holes are made in the material of which the belt is composed and the disks are
placed on the belt so that the domed shanks project slightly through the material.
The wire is then threaded through the shank from the back and passes out again
at the back so that the wire not only connects the electrodes electrically but also
fixes them securely in the backing of however light a texture the latter may be.
Dated this 11th day of May 1892.
COMPLETE SPECIFICATION.
Improvements in or relating to Electro-medical Belts and
Appliances.
I ALEXANDER KNOX of 85 St. James' Road, Upper Tooting, S.W. London
Tutor, 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 :-
This invention relates to the electrodes or plates of metal used in electro medical
belts or other wearing appliances which are intended to produce and impart
currents of electricity to the person of the wearers, and also to the method of
fixing such electrodes onto or in the belt or backing material which forms the
body of the belt or wearing appliance.
The purpose of the improvements is to cheapen the cost of manufacture, to
provide direct contact between the disks and their connecting wires, to fix the disks
only by means of the connecting wire but so to arrange the latter that it does not
come in contact with the person of the wearer. According to this invention the
electrodes which are usually circular disks are made with a domed shank or
depression in their centre or otherwise in which are made two holes for the passage
of the connecting wire.
Holes are made in the facing material of which the belt is composed and the
disks are placed on the belt so that the domed shanks project slightly through the
material. The wire is then threaded through the shank from the back and passes
out again at the back so that the wire not only connects the electrodes electrically
but also fixes them securely in the backing, of however light a texture the latter
may be.
The annexed drawing illustrates the improved method of fixing the electrodes,
Fig. 1 being a part of a belt as seen on the side worn next to the wearer, Fig. 2 a

page_text: central section through such belt, Fig. 3 an elevation and Fig. 4 a section of one of
the electrodes.
A and B are electrodes usually of copper and zinc respectively conveniently
stamped out of sheet metal, C the connecting wire for which No. 37 copper wire
cord strand (7 strand) is most convenient as being sufficiently flexible. The ends
of the wire may be bent round and fastened by sewing or otherwise. D is the
facing material, E the backing. The electrodes may be connected in series or
parallel or in any suitable grouping to form one or more batteries.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The construction of electrode disks and method of connecting and fixing them
by means of the wire as described.
