COMPLETE SPECIFICATION.
Improvements in Tooth and other Brushes.
I WILLIAM HENRY MANN, of 49, Moreton Terrace, South Belgravia, London,
Buyer, 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 :-.
My invention relates to improvements in tooth and other brushes, and has for its
object to prevent the bristles from being cut by the sharp edges of the perforations
in which they are fixed, while at the same time providing means whereby the said
bristles may be more readily dried than heretofore.
In the accompanying drawings,
Fig. 1 is a longitudinal section of a tooth brush, made according to my
invention.
Fig. 2 is a cross section of the bristle part of the same.
Fig. 2 shows at an enlarged scale the shape of my improved perforations.
Fig. 3 is a plan of the back of the brush without the ornamental covering.
Fig. 4 is a plan of the same with such ornamental covering.
Fig. 5 is a plan of the back of a hair brush to which my invention is applied.
Fig. 6 is a horizontal section of the same.
Fig. 7 is a horizontal section of a nail brush similarly improved.
Fig. 8 is a plan of the back thereof.
Like letters of reference indicate corresponding parts throughout the figures.
According to my invention, I give the perforations a in which the bristle ris
usually fixed, a rounded form at the top, so as to prevent the bristles being cut by
sharp edges, as occurred with the perforations hitherto used.
I further form narrow slots s (Fig. 3) along the back c of the brush, these slots
left open in communication with the perforations a for ventilating purposes, that is
to say, in order to allow the easy access of air to the bristle for the purpose of drying
it promptly. It is a well known fact that heretofore the bristles of brushes became
speedily deteriorated in consequence of the air not finding a ready access thereto;
and one of the aims of my invention is to remedy this defect.
In Figs. 4 and 5 are shown various methods of ventilating brushes, while at the
same time providing ornamented backs, which enhance the outward appearance of
the brushes.
Each brush consists of a bar or frame, one end of which forms as usual a handle,
while the other is furnished with rounded perforations a, wherein the bristle » is
fixed.
The frames are covered with a back c perforated in the various manners shown,
so as to form designs or ornamentations of different shape and form, according to
taste.
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 :-
In hair, nail, tooth and other brushes, the rounded formation of the top of the
perforations, wherein the bristle is secured, in combination with the openings formed
in the back of these appliances, substantially as herein described and shown, and for
the purpose set forth.
Dated this 7th day of November 1891.
