We WALTER SHELVERTON FROST, of 92 Copeland Road, Peckham, London, in
the County of Surrey, Engineer, JEAN LODOIS MERIGOT, of 56 Conduit Street,
London, in the County of Middlesex, Medical Electrician, and GUSTAVE CHARLES
CHRISTIAN FEIN, of 56 Conduit Street, London, in the County of Middlesex,
Medical Electrician, do hereby declare the nature of our invention for "IMPROVE-
MENTS IN MEDICAL ELECTRIC HAIR BRUSHES AND APPARATUS" to be as follows:-
Our invention relates to improvements in the construction of Medical Electric
Apparatus to be used for accelerating the growth of the human hair and also for
the treatment of various diseases of the body for which electricity is a remedy.
In constructing a hair or a body brush according to our invention we provide it
with metallic bristles, preferably of crimped German silver, in clusters, rows or
groups which we prefer to isolate. from each other by ordinary bristles, but which
may be isolated by being set at some distance apart. or by any suitable non-
conducting material so that when connected with the electrical arrangement at the
back of the brush as hereinafter described certain groups, clusters, or rows form
the positive and others the negative pole of an electric circuit.
The result of this arrangement of the brushing surface of our brush in connection
with our improved arrangement of battery is, that when the surface is applied to
the skin in brushing the hair the skin itself completes a circuit of electricity
between one set of metallic bristles and the other and the body thus receives as
much of the electric effect as may be desired.
In the back of our brush we form a case or box made of insulated material in
which is placed a medical or an induction coil with a suitable battery to work the
same. The coil is provided with two circuits of copper covered wire, one called the
primary or battery circuit, and the other a secondary circuit. 'Mounted on one of
the coil cheeks, which must be made of insulating material, is a poised 'spring,
having a small piece of iron attached at the one end and arranged to project
exactly over the iron core in the said coil, and at the other end of the spring, were
it is fixed to the coil cheek, it is also made to connect with one end of the wire
forming the primary circuit of the coil; the aforesaid spring is bridged over by a
piece of metal carrying a contact pin, against which the spring rests, a wire-is-
connected to this bridge and to one pole of the battery, the other pole of the
battery being connected to a metal plate situated near the handle part of the brush ;.

page_text: opposite this plate is fixed a metal contact spring connected to which is the other
end of the primary circuit wire. In the handle of the brush. is a long slot in which
is placed a lever, of insulating material, working on a pin that is in the extremity
of the handle, the said lever continuing and projecting a little in the slot and
behind the contact-spring, which presses this lever outward, in such a way that
when the brush is taken hold of by the hand, the lever acting on the contact
spring and pressing it to the plate oposite, thereby makes contact with, and
completes the primary or battery circuit, which sets the coil at work-When the
brush is put down; the contact spring brings the lever to its normal position, at the
same time taking off the contact, which stops the action of the coil. The secondary
wire of the coil, has one of its ends connected to a metal plate placed on the back
and connected with the german silver wires, and forming the positive pole, a
connection also being made to a tube in the side of the case or box, and the other
end of the said secondary wire is in a like way connected to a similar plate and.
placed on the back and connected with the german silver wires that form the
negative pole, and connected in like manner to a small tube in the other side of
the case. By this arrangement when the brushes taken up, the lever sets the coil
working, and when applied to the skin of the body the positive and negative poles
are connected of the secondary circuit which is thus completed through the skin,
and shocks of the electric current are felt.
The brush can be used for all kinds of medical electric treatment, by placing it
on a table, and having a spring ring placed on the handle, as a substite for the hand,
to press the lever in for the purpose of working the coil arrangement, and attaching
wire cords to the brush by means of pegs at one end of them, fitting into the small
tubes at the sides of the case; and at the other end of these cords different
instruments may be attached; such as metal handles, sponges, conducting rods, etc,
& for the purpose of applying the electric current to all parts of the body that may
be desired. It will be readily understood that the coil arrangement could be placed
in a case on a table and electrical connection made to the brush, by means of two
wire cords, having pegs at the ends for the purpose of making electrical contact
with the coil case on the table, and the german silver wires forming the positive
and negative poles of the secondary circuit of the brush in the hand.
We may make circular or revolving Hair Brushes with a brushing surface
according to our invention, placing within the brush an electric arrangement as
above described, or connecting it with any suitable generator of Electricity.

In the back of our brush we.form a case or box A made of insulated mäterial in
which is placed a medical or an induction coil B with a suitable battery Ci to work

page_text: the same The coil B is provided with two circuits of copper covered wire, one D
called the primary or battery circuit, and the other E a secondary circuit.
Mounted upon a pillar. F. is a poised spring G, having a small piece of iron H
attached at its outer end and arranged to project immediately over the iron core of
the coil B. At or near the centre of the spring G, is a contact pillar I connected
by means of a wire D with one end of the wire forming the primary circuit of the.
coil B.:
One pole K of the battery C is connected by means of a spring with the above
pillar F which carries the spring G; the other pole L of the battery being connected
to à metal spring plate Msituated near the handle part of the Brush; opposite
this plate M is fixed a metal contact plate N connected to which is the other end
of the primary circuit wire D. Or I may mount on one of the coil cheeks, which
must be made of insulating material, a poised spring, having a small piece of iron
attached at the one end and arranged to project exactly over the iron core in the
said coil the other end of the spring, where it is fixed to the coil cheek, being. also
made to connect with one end of the wire, forming the primary circuit of the coil,
the aforesaid spring is bridged over by a piece of metal carrying a contact pin,
against which the spring rests, a wire is connected to this bridge and to one pole
of the battery. In the handle. of the brush is a long slot in which is placed a
lever O of insulating material, working on a pin P that is in the extremity of the
handle, the said lever O continuing and projecting a little in the slot and behind
the contact spring M, which presses this lever outward, in such a way that when
the brush is taken hold of by the hand,the lever acting on the contact spring and
pressing it to the plate N, thereby makes contact with, and completes the primary
or battery circuit D which sets the coil B at work-When the Brush is put down,
the contact spring M. brings the lever O to its normal position, at the same time
taking off the contact, which stops the action of the.coil. .
The secondary wire E of the coil B has one of its ends connected to a metal
plate, placed on the back and connected with the German silver wires S, and
forming the positive pole, a connection also being made to a tube T in the side of
the case or box A, and the other end of the said secondary wire E is in a like way
connected to a similar plate R and placed on the back and connected with the
German silver wires S¹ that form, the negative pole, and connected in a like manner
to a small tube T' in the other side of the case- -By this arrangement when the
Brush is taken up, the lever O. sets the coil B working, and when applied to the
skin of the body the positive and negative poles are connected of the secondary
circuit E which is thus completed through the skin, and shocks. of the electric
current are felt.
This brush can be used for all kinds of Medical electric treatment, by placing it
on a table, and having a spring ring or other suitable contrivance placed on the
handle, as a substitute for the hand, to press the lever in for the purpose of
working the coil arrangement, and attaching wire cords to the brush, by means of
pegs U, U, at one end of them, fitting into the small tubes T T at the side of the
case A, and at the other end of these cords different instruments may be attached,
such as metal handles, sponges, conducting rods, & for the purpose of applying the
electric current to all parts of the body that may be desired. It will be readily
understood that the coil arrangement, could be placed in a case on a table and
electrical connection made to the Brusb, by means of two wire cords, having pegs
at the ends for the purpose of making electrical contact with the coil case on the
table, and the german silver wires forming the positive and negative poles of the
secondary circuit, of the Brush in the hand.
