COMPLETE SPECIFICATION.
Improved Hair and other Brushes.
I, FRANK WESTON PRATT of 104 Edge Lane, Liverpool in the County of
Lancaster, 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 hair brushes, tooth brushes, bath brushes, flesh brushes,
or the like, and the invention is designed to enable the brush to be more readily
cleaned than previously, and the bristles to be easily repaired or renewed without
there being any danger of injuring the mount.
In carrying out my invention, I form the stock containing the tufts of hairs, wires,
bristles or fibre, separate from the handle or mount, and I provide any suitable
means for fastening this stock to the mount, such as clips, dovetails, clamps, slides or
screws, whereby easy removal and replacement are rendered possible. The stock
can be made of wood, as formerly, while the mount can be made ornamental and of
more expensive material, or, for a still better class of brush, the following substances
may be used for the stock, namely, compressed paper, papier-maché, metal,
vulcanite, composition, waterproofed or enamelled wood or other material not
affected by water.
The invention will be best understood from the following description, reference
being had to the accompanying drawings, in which:-
Figure 1 is a perspective view of one of my improved brushes, showing the stock
removed from the mount;
Figure 2, a side view, partly in section, showing the stock fastened to the mount;
and
Figure 3, an enlarged view of the fastening device.
In these:
A, is the mount formed with a dovetail a near the top of the handle: B, protruding
pins C, the bristle stock chamfered at one end to engage dovetail in the mount A:
D, holes to receive the pins B and E, a spring catch secured to the mount and
adapted to engage one end of the stock.
The stock is secured to the mount by pins B, dovetail a and catch E, by which
means it is firmly held in position. The stock is easily detached from the mount
by raising the catch E.
I have described one form in which my invention may be carried into effect, but
I wish it to be understood that I do not limit myself to any particular shape of
brush or to any particular fastening for securing the stock, but that, having once
027

page_text: given the general idea, other shapes or forms of brushes or means of fastening may
be employed.
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. In the manufacture of brushes, forming the brush stock separate or removable
from the mount, instead of making them in one piece, as previously, thereby
admitting of the bristle portion being easily removed for cleaning or renewal
without danger of injury to the mount, substantially as described.
2. The use, in combination with brushes in which the stock is formed separate
from the brush mount, of means substantially as described, whereby the stock can
be fastened to the mount when required for use, or entirely disconnected therefrom
for the purpose of cleaning or renewal.
3. The improved brush taken as a whole substantially as described.
