Improvements in Brushes.

I ROBERT BARNES SHEPHERD, of 56 West 46th Street, in the City, County
and State of New York, United States of America, Consulting 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:-
My invention relates to brushes and the manufacture thereof.
In the accompanying drawings I have shown two types of brushes embodying my
invention.
Figure 1 is a form of brush constructed according to my invention.
Figure 2 is another form of brush embodying my invention.
Figure 3 is a side view of the brushes shown in Figures 1 and 2; and
Figure 4 is a section through the brush on line 4-4 of Figure 1.
As will be apparent from the drawings, the form of brush which I have shown is a
solid back brush pierced with openings or interstices, leaving a series of bristle
carrying bars and if desired, strengthening or non-bristle carrying bars.
In the drawings, A is a brush back shown as solid and provided with a handle B.
This brush back is provided with a series of interstices a with intervening bars b
which may be strengthened by bars c. The bars b carry tufts of bristles d, as clearly
exhibited in Figure 4, which tufts of bristles are inserted in the said bars and held
in place in any suitable manner. The bars c are non-bristle carrying bars, that is to
say, no bristles are inserted therein, the bars c serving principally as strengthening
bars to make the structure rigid. The brush back may be of any desired shape and
the bars may run in any desired or convenient manner, the essential feature being
that there shall be interstices between the rows of bristles on the bristle carrying
bars, so that water or other cleansing liquid may be freely run through the open
back thus constituted and on to the bristles to thoroughly cleanse them. In making
my brush, I first form the open back, preferably by moulding it from celluloid in a
die and thereupon insert the bristles with a retaining means to retain them in their
place in the bristle carrying bars.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A brush comprising an open back made up in part of bristle carrying bars with
open spaces or interstices intervening between the bars.
2. An open back brush carrying rows of bristles in its solid portions.
3. An open back brush comprising bristle carrying bars and strengthening or
non-bristle carrying bars as described and illustrated with reference to the
drawing.
4. In a brush, the combination of a solid back comprised in part by bristle
carrying bars with interstices between them and bristles secured in the bars.
5. A solid back brush provided with bristle carrying bars and openings between
the said bars for cleansing purposes.

page_text: 6. An open back brush comprising substantially parallel bristle carrying bars as
set forth.
7. The herein described process of making solid back brushes which consists
in forming a foraminous solid back and inserting bristles in the said back, as
specified.
8. The herein described process of making brushes consisting in moulding a
foraminous solid back and securing bristles therein.
9. The process of making brushes consisting in moulding a foraminous solid
celluloid back and securing bristles in the said back, as set forth.
10. A brush comprising a back having bristle carrying bars running from edge to
edge with interstices between the bars.
