PROVISIONAL SPECIFICATION left by the said Alexander Melville Clark at

ALEXANDER MELVILLE CLARK, of Chancery Lane, in the County of Middlesex,'
Patent Agent. "AN IMPROVED BINDER FOR PAINT AND OTHER BRUSHES." [A.
communication from abroad by Mark Worsnop Marsden, of Connellsville, in the.
County of Fayette, State of Pennsylvania, United States of America.]
This Invention consists in a band or tube of india-rubber or other elastic material,
having straight or tapered sides, as may be desired, which band is used in connection
with paint brushes or other brushes for the purpose of confining the bristles. The
elastic binder is made of such a size as to fit tightly upon the head of the brush.
over the binding wires that retain the bristles.
In using the said device it is slipped over the brush head, upon which it is held
by its elasticity, and the band is to be sufficiently long to extend upon the bristles. .
The end of the band that comes around the bristles, and, if desired, both ends are
formed with an enlarged rim or head to protect the edges from wear and give a
stronger compression at those points. The said elastic binding retains the bristles
in a compact bunch with an elastic pressure that gives readily under the manipula-
tions of the brush when in use, and prevents the brush from getting out of shape.
It will be understood that the shape of the binder will conform to the brush upon
which it is to be used, and when made tapering, the smaller end that comes upon
the bristles is to be of such size that it will exert the required compression upon the
bristles.
The binder when made of india-rubber is to be moulded and vulcanised in the
usual manner.

Patent Agent.
"AN IMPROVED BINDER FOR PAINT AND OTHER BRUSHES."
communication from abroad by Mark Worsnop Marsden, of Connellsville, in the
County of Fayette, State of Pennsylvania, United States of America.
This Invention consists in a band or tube of india-rubber or other elastic material
having straight or tapered sides as may be desired, which band is used in connection
with paint brushes or other brushes for the purpose of confining or bridling the
bristles. In using the said device it is slipped over the brush head, upon which it
is held by its elasticity, and the band is to be sufficiently long to extend upon the
bristles. The end of the band that comes around the bristles, and, if desired; both
ends are formed with an enlarged rim or head. The said elastic binding retains the
bristles in a compact bunch with an elastic pressure that gives readily under the
manipulations of the brush when in use, and prevents the brush from getting out
of shape.
In the accompanying Drawing, Figure 1 represents a paint brush with the
improved binder or bridle applied thereto; Figure 2 is an elevation of the binder
detached; and Figure 3 is a cross section of the binder on the line x, x, of Figure 2.
Similar letters of reference indicate corresponding parts in the different Figures.
A is the elastic binder or bridle; it consists of a band or tube of india-rubber or
other suitable elastic material, of such size that it will fit tightly upon the head of
the brush over the binding wires that retain the bristles. The binder A is long
enough to extend upon the bristles next to the brush head; b is a rim or bead formed
at one or both ends of the binder to protect the edge from wear and to give a
stronger compression at those places. In using the above-described device, it is
placed upon the brush head, as shown in Figure 1, and will be retained in place by
its elasticity drawing it tightly to the brush. The end of the binder laps upon the
bristles, and by its elasticity binds them together and prevents them from spreading
and getting out of shape. The binder will give to the bending of the bristles when
the brush is in use. The binder is shown circular in form, but it is to be under-
stood that its shape is to conform to the brush upon which it is to be used; it is
shown tapering, and the smaller end that comes upon the bristles is to be of such
size that it will exert the required compression upon the bristles. The binder when
made of india-rubber is to be moulded and vulcanised in the usual manner.
Having described the nature of the Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is,-
The elastic binder or bridle for brushes herein set forth, consisting of a cylindrical
or other shaped tube of india-rubber or similar elastic material substantially as
described.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set my
hand and seal, this Twenty-first day of March, in the year of our Lord One
A. M. CLARK. (L.S.)
