IMPROVEMENTS IN APPARATUS FOR EMPLOYING ELECTRICITY FOR CURATIVE AND REMEDIAL

County of Devon, Machinist, for the Invention of "IMPROVEMENTS

page_text: and remedial purposes; and secondly, in the construction of certain
appliances by means of which such currents of electricity can be con-
veniently and efficaciously applied to those parts of the patient to which
it is desired to impart the electric influence.
The electro-magnetic instrument is formed with a conical coil of
insulated wire spirally arranged and capable of allowing a central
column or core composed of a bundle of soft iron wires to be placed
within the same, such core becoming an electro-magnet when the instru-
ment is placed in connection with the requisite battery or batteries, as
will be well understood. The coil is placed in a horizontal position on a
stand, and the core is capable of being inserted or withdrawn, as may be
desired, by means of any suitable contrivance provided for that purpose.
The spiral conical coil is so wound that it forms a gradation or series of
parts commencing with a given diameter and number of spirals at the
small end of the coil, and gradually increasing in diameter with
increasing numbers of spirals towards the larger end thereof. The coil
is placed in connection with the requisito battery or batteries, and by
inserting or withdrawing the soft iron core the force of the electric
current can be readily proportioned to the requirements of each par-
ticular case for which the instrument is used.
For the purpose of enabling the operator to proportion the force of
the clectric current as may be requisite a graduated scale is attached to
the instrument, by which the insertion or withdrawal of the soft iron
core, with reference to the conical coil, and consequently the strength
of the current, can be regulated and noted. One or more batterics may
be used in connection with cach instrument, as may be desired.
The appliances to be used in combination with the apparatus herein-
before described consist of metallic pieces (by preference silver plated)
which are capable of being locally applied for the treatment of affections
connected with the abdomen, the spine, the renal region, the rectum,
and other parts, for which purposes they are formed of the requisite
shapes and sizes, and upon being placed in electric circuit with the before
mentioned apparatus, impart the influence of the electric current to the
region or part to which they are applied in the most effective manner,
and subject to the most perfect control on the part of the operator.

filed by the said Joseph Ralph Chislett in the Great Seal Patent
Office on the 8th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
RALPH CHISLETT, of Plymouth, in the County of Devon, Machinist,.
send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of January, in the
year of our Lord One thousand cight hundred and seventy-three, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Joseph Ralph Chislett, Her
special licence that I, the said Joseph Ralph Chislett, my executors,"
administrators, and assigns, or such others as I, the said Joseph
Ralph Chislett, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great.
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN APPARATUS FOR EMPLOYING ELECTRICITY FOR CURATIVE
AND REMEDIAL PURPOSES, AND IN APPLIANCES TO BE USED IN CONNECTION THERE-
WITH," upon the condition (amongst others) that I, the said Joseph
Ralph Chislett, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Ralph Chislett, 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, reference being made to the Draw-
ings hereunto annexed, and to the figures and letters marked thereon,
that is to say :-
-
My said Invention consists, firstly, in an improved method of con-
structing electro-magnetic apparatus for the application of electric
currents of greater or lesser intensity and strength, as may be desired,

page_text: for curative and remedial purposes; and, secondly, in the construction
of certain appliances by means of which such currents of electricity can
be conveniently and efficaciously applied to those parts of the patient to
which it is desired to impart the electric influence.
I will in the first place describe the electro-magnetic instrument which
is formed with a conical coil of insulated wire spirally arranged, and
capable of allowing a central column or core composed of a bundle of
soft iron wires to be placed within the same, the core becoming an
electro-magnet when the instrument is placed in connection with the
requisite battery or batterics, as will be well understood. The coil is
placed in a horizontal position on a suitable position, and the core is
capable of being inserted or withdrawn, as may be desired, by means of
any suitable contrivance adapted and provided for that purpose. The
insulated wire constituting the conical spiral coil is so wound that it
forms a gradation or series of parts commencing with a given diameter
and number of spirals at the smaller end of the coil, and gradually
increasing in diameter with greater numbers of spirals towards the
larger end thereof. The coil is placed in connection with the requisite
battery or batterics, and by inserting or withdrawing the soft iron core
the force or intensity of the electric current can be readily, and at
pleasure, in accordance with the principles which govern the production
and maintenance of primary and induced currents of clectricity, pro-
portioned to the requirements of each particular case for which the
instrument is used.
For the purpose of enabling the operator to proportion the force of
the electric current as may be requisite a graduated scale is attached to
the instrument, by which the insertion or withdrawal of the soft iron
corc, with reference to the conical coil, and consequently the strength of
the current, can be regulated and noted. One or more batteries may be
used in connection with each instrument, as may be desired.
The appliances to be used in combination with the apparatus herein-
before described, and upon which the efficacy of the latter to a great
extent depends, consist of metallic pieces or plates (by preference silver
plated) which are capable of being locally applied for the treatment of
affections connected with the abdomen, the spine, the renal region, the
rectum, and other parts, for which purposes they are formed of the
requisite shapes and sizes, and upon being placed in electric circuit with
