COMPLETE SPECIFICATION.
An Improved Brush for Lithographic Stipple Work.
We, GUSTAV ARNOLD, Lithographic Artist, of 293, Marion Street, Brooklyn,
in the County of Kings and State of New York, and CARL HILLE, Lithographic
Artist, of 40, 5th Street, Hoboken, in the County of Hudson and State of New
Jersey, both in the United States of America, 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 :-
A further
Our invention relates to an improvement in stipple brushes and has for its object
to provide a brush especially adapted for lithographic work, a further object of the
invention being to construct the brush of a yielding or elastic material, essentially
of conical shape and provided with an embossed or teated "technic."
object of the invention is to provide a brush wherewith an artist may produce a
stipple surface of a strong, light, or intermediate tint in an expeditious, convenient
and artistic manner, the brush being capable of manipulation in like manner to one
employed in painting.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar figures and letters of reference indicate corresponding
parts in both the views.
Figure 1 is a side elevation of the brush and handle partly in section; and
Figure 2 is a transverse section through the brush.
The brush A is made of rubber, or an equivalent elastic or yielding material.
The shape of the brush is conical, and the outer surface of the brush, known as the
"technic," is provided with a series of teats 10, or the equivalents thereof, of like
material to the body of the brush, the teats being preferably regularly arranged so
that when color is applied to them and the brush is manipulated upon a surface
adapted to receive color a stipple effect will be produced upon said surface.
The inner end of the brush, which corresponds to the base of the cone, is clamped
by or otherwise attached to a block 11, provided with a socket 12 at one end
receiving the body of the brush and having an extension 13 at the opposite end,
the said extension being round in cross section. The exterior surface of the
block 11, near the inner end thereof, is exteriorly threaded to receive a collar 14,
the said collar having a swivel connection with a handle 15. The handle may be
curved as illustrated, or may be given any desired shape most convenient to the
operator. The handle at its lower end is provided with a bore 16, in which the
extension of the block 11, is loosely fitted. It will thus be observed that the brush
may be readily revolved independently of the handle.
By reason of the conical shape of the brush, if so desired, it may be used at its
point or apex in like manner to an ordinary pencil employed in oil or water-color
painting. This form of brush enables an artist to perform work very quickly and
artistically in an equivalent manner to painting. According to the amount of
pressure exerted upon the brush a stronger or a lighter tint of stippling is
obtained.
With the brush described, work may be done upon a polished or upon a crayon
stone without interfering with work previously placed upon the stone with crayon
or with ink. The brush may also be readily used upon paper for sketching or for
ink drawing.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is,
-
1. A brush for stipple work, constructed of an elastic or yielding material,
tapered essentially to a point and provided with exterior teats constituting the
"technic" of the brush, as and for the purpose specified.
2. In a brush for stipple work, the combination, with the brush proper, con-
structed of an elastic or yielding material and provided with exterior teats
constituting its "technic," of a handle swiveled to one end of the brush, as and for
the purpose specified.
3. A brush for stipple work, comprising a handle and a body swiveled to the
handle, the said body being constructed of a yielding or elastic material tapered in
the direction of one end and having its exterior surface or "technic" provided with
a series of teats, as and for the purpose set forth.
