I, FREDERICK WILLIAM DICKINSON of Byrom Street Liverpool in the County
of Lancaster Brush Manufacturer 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 the improvement of the ordinary long bristled
paint brush. A new brush of this discription has to be bound with wire for some
distance from its base, say as far as line A B of Figure 3 of drawings annexed
hereto, in order to prevent the long leverage of the bristles causing the brush to
come to pieces, and the bristles have to be of the best quality. Even then painters
find that they have to bind them round with string or its equivalent before they
can use them properly, after they have worn somewhat the string is taken off, and
after further wear, the brush is too stumpy for further use, and is thrown away.
Now my invention is designed to avoid the necessity of binding with string, and
to enable the brush to be worn down considerably further than at present, without
becoming too stumpy for use.
The drawings hereunto annexed describe the invention.
In these Figure 1 is an end view of the ordinary handle with my improvements
attached, but without bristles or binding.
Figure 2. side view of same.
Figure 3. well worn brush in accordance with my invention.
Figure 4. new brush as improved by me.
The wood stock of brush is made in two parts A and B. The part B is movable
being securely tenoned into part A. The bristles are securely bound to the stock
in two (or more) places by copper wire, or its equivalent, namely at C and D.
The two bindings are quite distinct and in no way connected with each other.
The binding at D secures the bristle to the movable portion of stock.
When the brush has been in use some time and the bristles getting too short,
the binding D can be cut, and the movable portion of stock removed without in
any way affecting the binding at C, so that the bristles can then be worn down to
stock A. The part B is fastened to the handle C by the copper or other
wire E tightly stretched over it, and fastened down by nail F. F. at each end.

continuation of handle to receive further wire mousing or lashing J. K bristles.
It will be seen that while an ordinary brush is only bound round to the line A, B,
and supported by the handle, my improved brush is bound round to much more
than double this height and supported by both handle and piece D. By my
invention I claim that the consumer has the use of close upon an inch more bristle
in the brush than in the old or present style of manufacture, as in being bound in
two distinct parts the top or D binding keeps all pressure in use of brush from
binding at C until binding D is cut or taken away, so that no pressure being put
on C binding until binding at D is cut, enables me to bind at C with considerably
less number of ties than is usual in the present make, and will be quite firm
enough for its requirements namely, to hold the second half of brush while in use,
so that consumers will be able to use the brush until the bristles are almost worn
away, which is impossible in the present method of manufacture. A considerable
economy is thereby effected. Also the binding at D will ensure the brush having
the proper amount of spring, and will do away with the painter having to bridle
his own brush as is the case at present, and will at the same time keep the bristles
at a proper or full spread, which is not the case when the painter has to bind or
bridle his own brush. My invention applies to all kinds of paint brushes either in
a round or flat stock, as the brush can be made in exactly the same manner of
binding with the difference that the stock or wood will be round instead of flat, as
shown in my plan herewith. In the drawing I have only shown one continuation D
of the handle, and one additional wire binding, but there can be more than one of
each of these and each cut away in succession if desired.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. The manufacture of paint brushes with one or more adjustable lengths of
mid rib or handle tongue and with two or more bindings (C. D.) substantially as
described, by which means the brush can be made stiff at start, and when worn
can be again made flexible by the removal of some or all of the extra parts.
2nd. The combination of the handle C and shallow binding H with the sub-
sidiary binding J and additional removable piece D, by which means the final
remaining or lowest binding can be safely made much shallower than in ordinary
brushes and the brush thus be available when worn down to that point where
ordinary brushes would be useless.
3rd. The improved paint brush, substantially as herein described.
