Complete Specification Accepted, 20th Apr., 1889
I, GEORGE LUSH PEARSON of 73 Devonshire Road, Holloway, in the county of
Middlesex, Mechanical Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in revolving hair-brushes, and has for object
to produce a brush which revolves automatically and is self contained.
In carrying out my invention I construct the brush with a spindle having at ono
end a handle loosely attached. The said spindle is formed hollow to enable it to be
placed on, and fixed by means of a catch, to a spindle of a clockwork mechanism,
also provided with a handle, which serves as a key to wind up the said mechanism, or
a separate key can be used. The said handle in conjunction with the other handle
serves to hold the brush while being used. By forming the brush detachable as
described I am enabled to use a brush of any required size and degree of hardness
with the one clockwork mechanism.
In the clockwork mechanism I provide a spring thumbpiece, to which is attached
a catch or brake which prevents the brush from revolving when the mechanism is
wound up. By operating the said catch or brake the brush will be allowed to revolve
and its speed can be controlled and regulated.
By constructing a brush as described, I am enabled to dispense with the cumbersome
and expensive mechanism for driving the brushes at present used, thereby effecting a
great saving in cost.

page_text: I, GEORGE LUSH PEARSON of 73 Devonshire Road, Holloway, in the county of
Middlesex, Engineer, 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:—
This invention relates to improvements in revolving hair brushes and has for object
to produce a brush which revolves automatically and is self contained.
In carrying out my invention I construct the brush with a spindle having at one
end a handle loosely attached. The said spindle is formed hollow to enable it to be
placed on and fixed by means of a catch, to a spindle of a clockwork mechanism or
other motor also provided with a handle which serves as a key to wind up the said
mechanism or a separate key can be used. The said handle in conjunction with the
other handle serves to hold the brush while being used.
In the clockwork mechanism I provide a spring thumb piece to which is attached
a catch or brake which prevents the brush from revolving when the mechanism is
wound up. By operating the said catch or brake the brush will be allowed to revolve
and its speed can be controlled and regulated.
.
To enable my invention to be fully understood I will describe it by reference to the
accompanying drawing in which,
Figure 1 is a longitudinal sectional elevation of a revolving hair brush constructed
according to my invention and,
Figure 2 is a transverse section on the line A A of figure 1.
Similar reference letters indicate the same parts in both the figures.
a is the spindle carrying the brush b and provided with the handle c loosely mounted
on the said spindle. is the hollow part of the said spindle, the said part d engaging
with the square end e of the spindle of the clockwork mechanism g (or other motor)
which is mounted in a case g₁. is the spring catch to fix the spindles a and ƒ
together. The clockwork mechanism g is also provided with a handlo i, mounted
on a spindle it, and which handle serves as a key to wind up through the medium
of gear wheels j, k the coil spring contained in the barrel 1, a spring pawl m
engaging with the gear wheel to prevent the said coil spring unwinding and rotating
the said handle.
Instead of the handle i a separate key can be used.
The two handles c and i serve to hold the brush while being used.
The barrel is provided with a gear wheel n which engages with a gear wheel o on
the spindle f.
p is a fly connected to the gear wheel n by a train of wheels g in order to allow the
brush to rotate at a uniform speed.
By forming the brush b detachable as hereinbefore described I am enabled to use
brushes of any required size and degree of hardness with the one clockwork mechanism
or other motor.

page_text: is the spring thumb piece pivotted to a loose sleeves on the handle i, the said
sleeve being provided so that the said handle can be rotated without affecting the
thumbpiece r. The thumb piece is attached to a catch or brake t which enters
the case g¹ and normally projects in the path of movement of the fly p in
order to prevent the brush 6 from revolving when the mechanism 9 is or has been
wound up.
Instead of the catch or brake projecting in the path of movement of the
fly p it can be caused to press upon the spindle p¹ of the said fly for the same
purpose.
By depressing the thumb-piece the catch or brake t will be caused to move out of
the way of the fly p, and if the mechanism g has been wound up, the gear wheels n and o
will cause the brush to revolve, its speed being controlled and regulated by means of
the said catch or brake t.
If it be required to stop the brush revolving, it is only necessary to release the
thumb piece r.
By constructing a brush as hereinbefore described I am enabled to dispense with the
cumbersome and expensive mechanism for driving the brushes at present used, thereby
effecting a great saving in cost.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A revolving hair brush combined with and operated by a clockwork or other
motor substantially as described.
2. In a revolving hair brush of the kind claimed in claim 1, forming the brush
detachable from the motor substantially as and for the purpose described.
3. In a revolving hair brush of the kind claimed in claim 1, the use of a catch or
brake for stopping starting and controlling or regulating the speed of the said brush
substantially as described.
4. In a revolving hair brush of the kind claimed in claim 1, arranging one of the
handlos so that it can wind up the operating mechanism substantially as described.
5. The combination of parts forming the improved revolving hair-brush substantially
as described and represented in the accompanying drawing.
Dated this 15th day of March 1889.
GEORGE LUSH PEARSON.
