An Improvement in the Manufacture of Whitewashing, Plastering,
and other Brushes, whereby the Bristles are Rendered More
Secure.
We, DAVIS BURROW, and ALFRED LINLEY BURROW, trading together under the
style or firm of Davis Burrow and Sons, of Whitehouse Street, Hunslet Road, Leeds, in
the County of York, Brush Manufacturers, do hereby declare the nature of this inven-
tion to be as follows:-
Our said invention consists of an attachment to Nailed Whitewashing or Plastering
Brushes, either flat or round; Limer Brushes; Paper Hangers' Brushes; and others,
whereby the bristles are prevented from being pushed back from their bindings on
to the handles, and thus causing the brushes to come to pieces.
We take a piece of metal, (Tin, Zinc, Iron, Copper, or Brass,) corresponding in
length and width, with the width and thickness of the Brush over the binding; and
in this metal we stamp or cut, in a longitudinal direction, a space corresponding
exactly in length and width; with the width and-thickness of the handle below the
roots of the bristles, in a serrated or waved, or straight form, as may be most con-
venient, which centre part is then forced outwards at right angles, thus forming a
longitudinal flanged socket.
The flanged socket herein described is then passed over the end of the handle to its
position at the roots of the bristles, and the peculiar form in which the centre is cut
and turned outwards forms sufficient depth to enable the metal to be firmly nailed or
rivetted to the handle, and the flange fitting closely against the roots of the bristles
affords a support all round the brush which prevents the bristles being pushed
backwards.
In order to afford the same protection to round whitewash brushes we cut a flanged
socket from a round disc of metal corresponding in diameter with the diameter of the
brush outside the binding, and proceed as before described.
In order to demonstrate the application of our invention we append hereto drawings
explanatory of the foregoing:-

An Improvement in the Manufacture of Whitewashing, Plastering,
and other Brushes, whereby the Bristles are Rendered More
Secure.
We, DAVIS BURROW, and ALFRED LINLEY BURROW, trading together under the
style or firm of Davis Burrow and Sons, of Whitehouse Street, Hunslet Road
Leeds, in the County of York, Brush Manufacturers do hereby declare the nature of
our invention for AN IMPROVEMENT IN THE MANUFACTURE OF WHITEWASHING, AND
OTHER BRUSHES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our said invention consists of an attachment to Nailed Whitewashing, or Plastering
Brushes, either Flat or Round; Limer Brushes; Paper Hangers' Brushes; and
others, whereby the bristles are prevented from being pushed back from their
bindings on to the handles.
In order that the practical utility of our invention may be clearly apparent, we will
first describe the usual mode of construction of Nailed Flat Whitewash Brushes; and
also the cause of the bristles becoming loose, and the brushes falling to pieces; after
which we will describe the improvement we propose and which constitutes our
invention.
Nailed Flat Whitewash Brushes are usually made by placing a uniform quantity
of bristles or similar material at each side and around the ends of a wood handle, and
securing the bristles thereto by means of a continuous strip of leather or metal nailed
over the bristles as tightly as possible, after which the butt or root ends of the bristles
are burnt or singed with a hot iron, thus causing their cohesion. In this form the
brushes are usually sold, but it is found, when put into use, that by reason of the
handles drying-in, the bindings are considerably slackened, and therefore when
pressure is put upon the face of the brushes, the bristles, (being naturally thicker at
the butt or root ends,) are forced back upon the handles, thus causing the brushes to
fall to pieces as before mentioned.
The means hitherto adopted to remedy this defect have been, either to soak the
brushes over the handles in water before using, thus causing the wood to swell; or
to nail separate strips of wood or metal across the handles, at each side and, and
against the roots, to prevent the bristles being forced back. Both these methods are
found objectionable for the following reasons, viz. :-the first, because it is necessary
to soak the brushes every time they are used, and when such brushes are required to
be used dry, as in Paper-hanging, this method is impracticable; and the second
method is found to be very cumbersome and comparatively expensive, and is very
rarely resorted to.
Our invention is intended to prevent the falling to pieces as described in the fore-
going in a neat and economical manner, and at the same time more effectively than any
process which has hitherto been adopted.
We propose to take a thin piece of metal, either Tin, Zinc, Iron, Copper or Brass,
corresponding in length and width, with the width and thickness of the brush over

page_text: the binding, and in this piece of metal we stamp or cut, by means of an ordinary
cutting press or stamp, in a longitudinal direction, and in a space corresponding in
length and width with the width and thickness of the handle below the roots, a
design in a serrated or waved or straight form as may be most convenient. The centre
part of the metal is then forced outwards at right angles, thus forming a longitudinal
flanged socket, the flanged part of which corresponds in width with the thickness of
the roots of the bristles standing out from the handles.
The flanged socket herein described is then passed over the handle to its position
at the roots of the bristles, and the peculiar form in which the centre is cut and turned
outwards forms sufficient depth to enable the metal to be firmly nailed or rivetted to
the handle, and the flange fitting closely against the roots of the bristles affords
a support all round the brush which prevents the bristles being forced backwards.
In order to afford the same protection to round whitewash brushes we cut a flanged
socket from a round disc of metal corresponding in diameter with the diameter of the
brush outside the binding, and proceed as before described.
That our invention may be clearly understood we refer to drawings left with our
Provisional specification, No. 17981, of 31st December, 1887.
Figure 1. shews a Nailed Flat Whitewash Brush as hitherto made; A. Bristles ;
B. B. strip of leather or metal nailed round the bristles, and binding them to the
handle; C. C. shews where the bristles usually become loosened and pushed back on
to the handle when the brush is in use.
Figure 2. represents the plain piece of metal before the centre design is cut, the
total length of which corresponds with the width of the brush from B to B in
Figure 1. and the width of which is equal to the thickness of the brush over the
binding.
Figure 3. represents the piece of metal as stamped or cut in a waved form, (which
form we propose to vary as may be expedient) and before the centre is turned
outwards.
Figure 4. represents the metal with the centre turned outwards at right angles
ready for fixing upon the brush, the centre space corresponding in length and width
with the width and thickness of the handle at D. D in Figure 1.
Figure 5. is an enlarged section of the flanged socket through E to F in
Figure 4.
Figure 6. shews the brush as finished with the flanged socket rivetted on, ready
for use.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. The combination of a flanged socket as herein described, with ordinary White-
wash or other brushes, whereby the bristles are rendered more secure.
2: Novelty of the design of the Flanged socket, made from one piece of metal
without joint, which, by having its centre cut in a waved or serrated form, gives
sufficient depth for rivetting to the handles, however thin they may be while
the flange is of sufficient width to withstand the backward pressure of the bristles.
