Improvements in and relating to Rotary Brushes.
We, THE ELECTRICAL COMBINATIONS COMPANY, of 11, Victoria Buildings,
Manufacturers, and WILLIAM HENRY DINGLE, of 15, Hindon Street, Engineer,
both in Pimlico, in the County of Middlesex, do hereby declare the nature of this
invention to be as follows:-
:-
Our invention relates to rotary brushes of that class which are used for brushing
the hair of human beings, for grooming animals, and for similar purposes.
Such brushes as hitherto used, have usually been operated by power communicated
them through the medium of a belt or flexible shaft.
According to our said invention we arrange a motor within the brush itself thereby
avoiding the necessity for using a cumbersome machine for obtaining the motion.
In carrying our invention into practice we preferably use an electric motor which
is mounted on a central shaft extending longitudinally through the brush and having
at its ends the handles for holding the brush. The body of the brush is geared to
the shaft of the motor so that when the armature is caused to rotate the brush will
rotate also.
The electric current is preferably conveyed to the motor through one of the handles,
and a switch or push is placed in this handle in such a manner that it will only be
depressed to complete the electric circuit when the brush is grasped by the hand.
Instead of using an electric motor I may employ any other suitable form of motor.
Dated the 15th day of June 1888.

Improvements in and relating to Rotary Brushes.
We, THE ELECTRICAL COMBINATIONS COMPANY, of 11, Victoria Buildings,
Manufacturers, and WILLIAM HENRY DINGLE, of 15, Hindon Street, Engineer,
both in Pimlico, in the County of Middlesex, 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 :-
Our invention relates to rotary brushes of that class which are used for brushing
the hair of human beings, for grooming animals, and for similar purposes.
Such brushes, as hitherto used, have usually been operated by power communicated
to them through the medium of a belt or flexible shaft.
According to our said- invention, we arrange a motor within the brush itself,
thereby avoiding the necessity for using a cumbersome machine for obtaining the
motion.
In carrying our invention into practice, we preferably use an electric motor which
is mounted on a central shaft extending longitudinally through the brush and having
at its ends the handles for holding the brush. The body of the brush is geared to
the shaft of the motor, so that when the armature is caused to rotate the brush will
rotate also.
The electric current is preferably conveyed to the motor through one of the
handles, and a switch or push is placed in this handle in such a manner that it will
only be depressed to complete the electric circuit when the brush is grasped by the
hand.
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawing, in which
Figure 1 is a side elevation of a rotary brush provided with our improvements, a
portion of the body of the brush being removed in order to show the electric motor
arranged within the same.
Figure 2 is a longitudinal section through the said brush, the motor being shown
in a position at right angles to that shown in figure 1, and
Figure 3 is an end view, one end of the body and the adjacent handle being
removed to show the motor.
a is the body of the brush, and b, b' are the end portions thereof.
c is the frame for carrying the motor, which frame is provided with arms d, d..
serving as an axis upon which the brush rotates. These arms project through the
ends b, b of the brush, and have secured to them the handles
e,
el.
fis an electric motor of well known construction which is carried in the frame c
by the screw and nut g. The armature shaft / of the said motor carries a pinion i
which engages with a gear wheel ; on a countershaft k, a pinion on the said
counter shaft gearing with a wheel m secured to the end 6 of the brush body.
n, n are binding screws attached to the handle e' for connecting the motor with the
source of electricity. It will be noticed by reference to figure 2 that the wires which

page_text: connect the screws n, n with the motor pass through the interior of the handle, so as
not to interfere with the rotation of the brush.
o is a contact device which is located in the handle e¹ and so arranged that the
electric circuit shall be normally broken; when, however, the handle is grasped,
the contact is operated so as to complete the circuit through the motor.
In using the brush, the motion of the armature is transmitted, as hereinbefore
described, through the pinions i, j, and I to the wheel m which is secured to the
brush, thereby imparting motion to the latter.
We wish it understood that any suitable form of motor either electric or otherwise
may be employed according to our invention, provided such motor is located within
the brush.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
(1.) The combination with a rotary brush, of an electric or other motor arranged
within the said brush and adapted to impart motion to the latter, substantially as
described.
(2.) The manufacture and use of a rotary brush having a motor arranged therein,
substantially as hereinbefore described with reference to the accompanying drawings,
for the purpose specified.
