Improvements in Brushes.
I, BYRON SEARS BAXTER of 72 Hope Street, Providence, in the County of
Providence, and State of Rhode Island, United States of America, Gentleman,
o hereby declare the nature of this invention and in what manner the same
s to be performed, to be particularly described and ascertained in and by the
ollowing statement:-
This invention relates to brushes, and particularly to a reversible brush and the
object of the invention is to provide a simple and inexpensive and durable brush
of novel construction.
A further object of the invention is to so construct the brush members that one
member will be required to adjust and seat itself upon the other member, by simply
screwing down the nut upon the bolt connecting said members without the necessity
of exact adjustment by hand. The invention consists in the novel construction and
arrangement of parts.
In the accompanying drawings forming part of this application:-
Fig. 1 is a perspective view of my brush with members in the act of being
reversed.
Fig. 2 is an enlarged perspective view of the brush members without bristles,
showing the members at an angle to each other.
Fig. 3 is a similar view showing the brush head member from the position
shown in Fig. 2.
Figure 4 is a cross section of Fig. 3.
The same numerals of reference denote the same parts throughout the several
figures of the drawings.
In carrying my invention into effect I construct two brush members one with a
concave inner surface and the other with a convex inner surface, and provide a
clamping device for drawing the members into alignment and so locking them
together.
The brush member 1, has a suitable handle 2, a central aperture 3, and its
inner surface is concaved throughout its length from one side edge to the other,
the outer surface being of any suitable shape, but preferably semi-circular as
shown.
The brush head member 4, that is the member which carries the bristles 5, has
its inner surface convexed from one side edge to the other throughout its length to
conform exactly with the concaved surface of the handle member 1. The member 4
has a central aperture 6, which registers with the aperture 3, of the handle
member 1, and has a square countersink 7, for the conical square head 8, of the
clamping bolt 9. This bolt is screw threaded and projects through the said aper-
tures, and is provided with a thumb nut 10, which does not have to be removed
sufficient to allow the members to clear each other, to accomplish this purpose, and
then tightened to bring the members in alignment and lock them together.
It is obvious that the contact surfaces of the brush members may be reversed, or
the curvature thereof made greater or less with the same result.
It will be observed that owing to the form of the contact surfaces the head member
when displaced does not require separate operation of handling to put it in exact
alignment or other precise position relative to the handle member to be locked

page_text: with the latter, but said contact surfaces having no projections or other obstructions
and the central location of the pivot bolt, and its length, the latter by operating
the nut will pull the head member into the seat in the handle member.
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 a reversible brush, the head member and the handle member, one of said
members being convexed from one side edge to the other, and the other of said
members being concaved from one side edge to the other, in combination with a
suitable pivot of sufficient length to permit the members to be reversed without
detachment, extending through the handle member and provided exterior thereto
with a nut adapted to be operated to seat one of said members in the other member,
ns set forth.
2. A reversible brush, comprising the brush bead member convexed throughout
its length from one side edge to the other, the brush handle member concaved to
conform with the said convex surface of the head, the pivot bolt of sufficient length
to permit the members to be reversed without detachment, extending through both
brush membors, and a suitable thumb nut, the latter being operated to seat the
head member, as set forth
