IMPROVEMENTS IN METALLIC BRUSHES, AND IN MEANS MEANS FOR THE LOCAL APPLICATION OF GALVANIC AND MAGNETIC CURRENTS
Year: 1882

page_text: LETTERS PATENT to George Ashworth and Elijah Ashworth, of the Firm of
Ashworth Brothers, of Manchester, in the County of Lancaster, Engineers, for
an Invention of "IMPROVEMENTS IN METALLIC BRUSHES, AND IN MEANS
PROVISIONAL SPECIFICATION left by the said George Ashworth and Elijah
Ashworth at the Office of the Commissioners of Patents on the 30th January
1882.
GEORGE ASHWORTH and ELIJAH ASHWORTH of the Firm of Ashworth Brothers
of Manchester in the County of Lancaster, Engineers. "IMPROVEMENTS IN
METALLIC BRUSHES AND IN MEANS FOR THE LOCAL APPLICATION OF GALVANIC
AND MAGNETIC CURRENTS."
Our Invention has for its object to produce improved means whereby galvanism
or magnetism may be applied to the head or to any part of the human body or to
parts of the bodies of animals. For such purposes we manufacture metallic
brushes having metallic connections between the wires or pins which take the
place of the bristles in ordinary brushes and an attachment for one of the wires or
conducting cords of a galvanic cell or battery or of an induction coil or of a
magnetic machine or an apparatus capable of generating a galvanic or magnetic
current. Ordinary hand made metallic bruslies may be adapted to the purposes
of our Invention but as the pins or wires in such brushes are not set sufficiently
close together to produce the best result we prefer to employ brushes having close
set fine wires made by machinery in accordance with our Patent Number 3909
of the year one thousand eight hundred and seventy six. In such a brush the
wires are beaded and are.inserted in an elastic foundation. We apply to the back
of the foundation that is to say between the said foundation and the brush back
or handle a conductor consisting of a plate of metal or a sheet of copper or metallic
foil or a substance or material capable of conveying a galvanic current the said
conductor being so applied as that it shall be in contact with the heads of the
Domina A71

page_text: wires. The said conductor is connected with an attachment on the brush back or
on any part of the brush. When the brush is used say for example in connection
with an ordinary medical induction coil apparatus having two circuit conductor
cords one of the said cords is hooked to the said attachment or is otherwiso
attached thereto and the other cord is connected with a conductor upon which the
person to be operated upon stands or other suitable arrangements are made for
completing the circuit. The head or any part upon which it
desired to operate
is now brushed and the current flows in numerous fine divided streams through
the pins or wires of the brush and is received by the surface being brushed and
flows through the body or a part of the body to the other circuit conductor.

Our Invention has for its object to produce improved means whereby galvanism
or magnetism may be applied to the head or to any part of the human body or to
parts of the bodies of animals. For such purposes we manufacture metallic brushes
having metallic connections between the wires or pins which take the place of the
bristles in ordinary brushes and an attachment for one of the wires or conducting
cords of a galvanic cell or battery or of an induction coil or of a magnetic machine
or an apparatus capable of generating a galvanic or magnetic current. Ordinary
hand made metallic brushes may be adapted to the purposes of our Invention but
as the pins or wires in such brushes are not set sufficiently close together to
produce the best results we prefer to employ brushes having close set fine wires
inade by machinery in accordance with our Patent Number 3909 of the year one
thousand eight hundred and seventy-six. In such a brush the wires are headed
and are inserted in an clastic foundation. We apply to the back of the
foundation that is to say between the said foundation and the brush back or
handle a conductor consisting of a plate of metal or a shoet of copper or metallic
foil or a substance or material capable of conveying a galvanic current the said
conductor being so applied as that it shall be in contact with the heads of the
wires. The said conductor is connected with an attachment on the brush back or
on any part of the brush. When the brush is used say for example in connection
with an ordinary medical induction coil apparatus having two circuit conductor
cords one of the said cords is hooked to the said attachment or is otherwise attached
thereto and the other cord is connected with a conductor upon which the person
to be operated upon stands or is held in one of his hands or other suitable arrange-
mments are made for completing the circuit. The head or any part upon which it
is desired to operate is now brushed and the current flows in numerous finely
divided streams through the pins or wires of the brush and is received by the
surface being brushed and flows through the body or a part of the body to the
other circuit conductor.
Having now fully described the nature of our said Invention and the manner
in which we carry the same into effect we would have it to be understood that we
claim backing the wires of metallic hair brushes with sheet metal or with metal
foil or with a material being a suitable electrical conductor and providing an
attachment for a wire cord or conductor so that the wires of the brush may form
part of an electric or galvanic circuit substantially as and for the purpose set forth.
In witness whereof I the said George Ashworth for myself and on behalf
of the said Elijah Ashworth have hereunto set my hand and seal this
Twenty-sixth day of July in the year of our Lord One thousand eight
hundred and eighty-two
