JOHN ELDRIDGE SPRATT, L.F.P.S-G-Physician 54 Brook Street Grosvenor
Square London, do hereby declare the nature of my invention for AN IMPROVED
BELT FOR ADMINISTERING ELECTRICITY FOR MEDICAL PURPOSES to be as
follows:-
This Belt consists of any number of terminals insulated from each other with
wires connecting them with a medical coil so as to receive Primory-Secondary-or
Alternating Currents either from the Coil or the Current from the Battery direct
to two or more of the terminals attached to the Belt, so connected to be in contact
with two or more of the terminals or any part of the Belt.

page_text: F JOHN ELDRIDGE SPRATT Licentiate of the College of Medicine and Surgery
Glasgow 54 Brook Street Grosvenor Square do hereby declare the nature of my
invention for THE ADMINISTRATION OF ELECTRICITY and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
1st The object of the invention is for the better administration of Electricity for
medical or surgical purposes both for human beings and animals.
2nd The principle of the invention consists of a Bandage or Belt of two portions
In one portion the instrument is so adjusted that the Electric Current can be
changed instantaneously from the negative to the positive or vice versa from the
Coil or the Battery direct.
3rd In the other portion the terminals consist of two handles or any number of
Wires at the end of which is placed a Disc attached to the Bandage or Belt so that
the electric current passes at any angle through the Body or Frame.
A, a belt to buckle round the body or limbs 1, 2, 3, 4, represent four discs (or
can be made for any number requisite) fixed in the belt or bandage to go next the
skin. To each of the discs a wire is fixed which passes along the belt and meets
the negative current, while on the other side of the belt or bandage an equal
number meets the positive. By this means an electric line may be passed from
one number to the opposite side through the hepatic regions, or chest, or body,
without shifting the belt.
B is supposed to be a wheel, with a given number of discs connected by wires to
the corresponding discs on belt, with plates marked 1, 2, 3, 4 and a swivel or pin
in the middle.
C is a wheel revolving .on pin in the centre of B To this wheel are fixed two
wires from the battery or cells, passing through and joining the two plates at E, 80
that this side of the wheel comes in contact with the wheel B. When the wheels
are placed together the electric current must pass through either of the numbers 1,
2, 3, 4, in a transverse form. If the handle or wheel C is turned the "half circle
the negative takes the position of the positive, or the right side to the left on the
belt A.
"
I must now remark it is important, in administering electricity, the "poles" too
must be changed, and it is equally essential as that of changing the primary or
quantity, to that of the intermittent or intensity. This instrument is so adjusted
that the patient can at his own discretion change the direction of the two currents
instantaneously, or in like manner change the poles, vice versa.
The advantage to be derived from this system of administering electricity is as
follows: "That a patient can instantaneously change the currents at his own
discretion," viz :-
1st From positive to negative.
2nd That the electric line can at pleasure be passed at any angle through the
body, frame, or limbs, without shifting the Belt or Bandage.
This speaks for itself, and scarcely requires repetition to those who are acquainted
with the administration of electricity for medical purposes-that, for example, in

page_text: curable epilepsy, above all other maladies where the nerves are so directly
implicated with disease of the heart and spinal cord, the modus operandi of its
administration is of the utmost importance. In every respect this instrument
meets all the requirements, as patients can apply it at their own discretion.
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 Belt combined with Discs B & E for applying Electricity substantially as
herein described."
