Improvements in the Manufacture of Brushes for Whitewashing,
Painting, and other purposes.
We, ALBERT HODGKISS, Manager of Brush Manufactory, of 29, Spring
Gardens, Manningham Lane, and GEORGE HENRY LAMMING, Brushmaker, of
79, Garnett Street, both in Bradford, in the County of York, do hereby declare
the nature of this invention, to be as follows:-
This invention relates to the manufacture of flat brushes such as are employed
for whitewashing, sizing, painting, washing walls and ceilings, and applying the
paste to paper-hangings. The chief object is to prevent the loosening of the
binding around the handle and so prevent the bristles or hairs from becoming
detached.
According to the usual methods at present practised in the manufacture of flat
brushes the bristles or hairs are either bound around the top end of the handle by
wire or twine or are tightly jammed against the handle by a strong binding of sheet
tin, zinc, or other metal. It is well known that these methods of attachment do
not prevent the bristles or hairs falling out.
In constructing a brush according to our invention we form the handle, at the top
part, of the same thickness of material as the other portion and omit the usual
tapering of the top. The binding for the bristles or hairs consists of a strong piece
of sheet metal, block tin for instance, of a tapering form, the narrowest part of the
taper being at top. This binding is joined together, preferably by solder, before-
hand at the sides and is turned over at the top and bottom edges, wire being first
inserted so as to form a beading, and then indented along the edges with a blunt
instrument, thus producing a strengthening flange around same. Through this
taper binding sufficient bristles or hairs, after bunching or knotting, are drawn
until they become tightly jammed therein, leaving a space at the lower part of the
binding for attachment of same to the handle. At one or more places inside the
binding a piece of sheet metal is fixed transversely and each such piece is secured
by glitting the binding opposite the ends of these pieces, so as to allow of their
passing partly through such slits and being bent over and attached by solder or
otherwise. These pieces pass right through the bristles and their ends extend
vertically to the top and bottom of the binding; a slit opposite each piece being
cut in the handle before insertion of same into the binding. The handle is now
forced into its socket in the binding until the top of same comes into contact with
the bristles, but not further, and may then be fixed in the usual manner, by passing
nails through the binding into the wood of the handle for instance. The transverse
pieces inside the binding will be found to effectually prevent bulging of the sheet
metal forming the binding even if the brush has been some days in the whitewash
or other liquid employed in using the brush, and thus it will be found impossible
for the bairs or bristles to become detached.

right up until tightly jammed therein, and finally trimmed off evenly. The
handle A, which may be of any suitable form, is then forced up until quite tight in
the binding, but not further than where the bristles begin, slits a (Fig. 5) being
first cut in the handle so as to clear the pieces D. The handle may then be
further secured by means of nails or screws, as at.ax, a*, Fig. 1.
The transverse pieces inside the binding will be found to effectually prevent
bulging of the sheet metal forming the binding even if the brush has been some
days in the whitewash or other liquid employed in using the brush, and thus it will
be found impossible for the hairs or bristles to become detached.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly-The improved construction of brushes for whitewashing, painting and
other purposes, substantially as described. in the Specification and shown on the
drawings.
Secondly-The employment of one or more transverse strengthening pieces D,
for preventing the bulging of the binding and consequent loosening of the bristles
or hairs of brushes used for the purposes and of the description specified and
shown.
