Improvements in or relating to Paint Brushes.
We, WILLIAM HART, Painter, and WILLIAM BONE, Painter, both of
10, Wharncliffe Street, Rotherham, in the County of York, 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 :-
This invention has for its object to dispense with the tedious process of preparing
paint brushes by the workmen, commonly called "binding" that is, when a brush
is required for small or narrow work such as window sashes for example, the
painter winds a fine piece of cord round the bristles from the junction with the
handle, to any desired distance towards the point, passes the ends of the cord
through the body of the bristles and then secures them to the handle, this as will
be seen shortens the working portion of the bristle, and the operation which is one
of constant recurrence takes up a good deal of time.
Our invention is illustrated in the annexed sheet of drawings, like letters of
reference indicate like parts in any of the figures.
Fig. 1, represents an ordinary paint brush.
Fig. 2, the same brush after binding in the ordinary way.
Fig. 3, an elastic binder.
Fig. 4, the elastic binder applied to a brush.
Fig. 5, an improved elastic binder.
Our invention consists in the substitution of an elastic tubular adjustable binder,
for the present method of winding a piece of cord round the base of the bristles
and then having to secure it by driving or forcing the ends into nicks made in the
handle or by the use of tacks.
An ordinary brush is shown in Fig. 1, in which the bristles A, are secured to the
handle B, by a tightly wound cord C; the bristles are of the usual length, but for
many purposes they would be too long as when pressed against the article to be
painted the bristles would spread out wider than was required.
To remedy this a cord D is pro tem. wrapped round the bristles as shown in
Fig. 2, until the point of exposed bristles is of the desired length for the work;
when it is required for broader work the cord D, has to be unwound either partially
or completely as the case may be.
In winding round the cord D, the shorter or worn bristles of the brush project
between the coils of the cord, and they must either be cut off, or they are liable to
be dipped into the paint can, and drop the paint about.
Our adjustable binder is made like a short piece of tube, as shown in Figs. 3, and 4,
and marked E, and preferably of indiarubber; it is made to fit tightly over the
brush in the position shown in Fig. 4, but so that it can be readily moved nearer to
or further from the point of the bristles as desired.
The improved binder being elastic, will yield somewhat to the action of the
bristles and not be so liable to break the bristles, as the rigid cord in Fig. 2.
We may also make the binder of elastic wire in the shape of a coil; or from a
piece of elastic sheet metal, or like elastic material bent round to a tubular form so
that it will expand or contract.
A binder made of rubber may have a projecting internal collar or moulding F,
and be ribbed on the outside as shown in Fig. 5.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same may be put into practice, we declare that what
we claim is :-
1-An adjustable elastic binder for paint brushes of tubular form, and made from
rubber, wire or other elastic material, substantially as hereinbefore described.

page_text: 2-The combination with a paint brush, of an adjustable elastic binder, of
tubular form, substantially as hereinbefore described and illustrated.
