An Improvement in Securing the Handles of Painting Brushes.
WILLIAM SIMPSON Brush Manufacturer 12 Castle Terrace Cathcart near
Glasgow, do hereby declare the nature of this invention to be as follows :-
A combination of clamps with one or more grooves having projections & recesses
on each side, with adjustable perforated steel plate to fit ou the top of the clamps
and made adjustable by set screws.
Also tube hollow to within about 1" inch from the top for the purpose of driving
handles into the brushes.
Tho clamps are drawn together by 2 screws. The projections and recesses on
each side acting as guide pius to keep the grooves perfectly even as the clamps are
being screwed together.
The bristlo part of the brush is drawn inside the ferrule or socket when inserted
into the groove. The ferrule or socket resting on the steel plate. The clamps are
Bcrewed together sufficient to hold the bristles firm. The pegs or wedges at the
end of handle are then driven into the butt ends of the bristles inside of ferrule or
socket.
The hollow tube is used as a cover or protection for all handles that have small
or sharp ends, in these cases the hollow tube which is shaped to fit the lower parts
of handle only is placed over samme and the blow required to drive the handle'
into its place, is struck on the top of the hollow tube, this prevents the handle
being injured.

An Improvement in Seouring the Handles of Painting Brushes.
WILLIAM SIMPSON 12 Castle Terrace Cathcart near Glasgow Paint Brush
Maker 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 :—
My invention relates to improvements in the method of securing handles to
painting brushes; and consists in the combination and arrangement of the devices
employed, as herein more fully set forth.
On the accompaning drawings,
Figure 1 represents a front elevation of my improved apparatus.
Fig. 2 represents a longitudinal section on the line A. B, shown in Fig. 1.
Fig. 3 represents a plan; and Fig. 4 represents a cross section on the line C D,
shown in Fig. 1.
Similar letters refer to similar parts wherever they occur on the drawings.
a a' represents a pair of clamps, provided with one or more grooves bbl, as
shown. To the clamp a is secured or made in one peice suitable guide-peices o cc,
that are located on each side of the grooves bb. Corresponding recesses d d are
made in the clamp a' for the guidance of the guide-peices c c. The projections

page_text: and the guide-peices cc and the recesses d d are shown circular in the drawings;
but they may to equal advantage be made as tongues and grooves, or iu a similar
manner. e represents an adjustable metallic plate, resting on the tops of the
clamps a a; as shown, and is made adjustable by means of the set screws ff, pro-
jecting through the slotted holes gg. The adjustable metallic plate e is provided
with one or more perforations, hhh, arranged centrally with the grooves bb', as
shown.
The object of the said metallic plate is to serve as a firm rest for the ferrule of
the brush to rest upon in case the clamps a a' are made of wood. The plate &
may be dispensed with if the clamps a al are made of metal.
In Fig. 2 i represents the bristles of a brush held in the grooves bb' of the
clamps a a'. represents the ferrulo, and I the handle, with its annular shoulder m
and lower projections n n. o represents a hollow tube, that is placed round the
handle 4, in such a manner that its lower end rests on the annular shoulder m. The
hollow tube o serves for the purpose of driving the handle into the brush which
is done by placing the handle in a position as shown on the right hand side of
Fig. 1. The hollow tool o can then be placed around the handle 1, in a position as
shown in Fig. 2, when the projections nn are easily driven into the brush by
giving a blow on the upper end of the hollow tube o. With handles that have not
got the annular shoulders m the hollow tube o is dispensed with, and are driven
into the brush by a blow on the top of handle l.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
'
1. The combination of the clamps a a' with one or more grooves, bb', having
projections c c, and recesses d d, on each side, and the hollow handle o, substantially
as and for the purpose set forth.
2. In combination with the clamps a a', with their grooves bb, projections oc,
and recesses d d, the adjustable perforated plate e, as and for the purpose set
forth.
3. In combination with the clamps a a' and their grooves 66, and plate e, the
hollow handle o, as and for the purpose set forth and described.
