IMPROVE- MENTS IN BRUSHES
Year: 1884

page_text: I ADDISON WILLIS ABRAHAM, of Savannah, in the State of Georgia, Brush
Manufacturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN BRUSHES" to be as follows:-
:-
Scrubbing brushes used with water, and brushes in manufacturing operations
used with liquids, soon break down through the fibres softened by the liquid
breaking or taking a permanent set. This is about equally the case with animal
and with vegetable fibre. Now my Invention is designed to prevent this by mixing
with the organic fibres non-corrosive non-absorbent mineral fibres that shall
remain unsoftened in hot water and thus keep the whole stiffer than would
otherwise be the case.
My Invention consists in mixing with the fibre thin flexible wires of copper,
bronze, brass, aluminium, plated iron, or other flexible elastic non-corrosive
material of about the same thickness or elasticity and flexibility as the bristle
when new and dry, or rather stiffer.
These metallic bristles are mixed with the others indiscriminately so that they
shall permeate all parts of the bunches of bristles, or they can be placed thickest
in those parts most exposed to a bending or breaking strain, while in other parts
they can be less frequent or absent altogether. I sometimes prefer however for
appearance sake to keep them entirely absent from the outside row of bristles.

page_text: I ADDISON WILLIS ABRAHAM of Savannah, in the State of Georgia, Brush
Manufacturer, do hereby declare the nature of my Invention for "IMPROVEMENTS
IN BRUSHES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
"
Scrubbing brushes used with water, and brushes in manufacturing operations
used with liquids, soon break down through the fibres softened by the liquid
breaking or taking a permanent set. This is about equally the case with animal
and with vegetable fibre. Now my Invention is designed to prevent this by mixing
with the organic fibres non-corrosive non-absorbent mineral fibres that shall remain
unsoftened in hot water, and thus keep the whole stiffer than would otherwise be
the case.
My Invention consists in mixing with the fibre, thin flexible wires of copper,
bronze, brass, aluminium, plated iron, or other flexible elastic non corrosive
material of about the same thickness or elasticity and flexibility as the bristle
when new and dry or rather stiffer.
These metallic bristles are mixed-with-the-others-indiscriminately so that they
shall permeate all parts of the bunches of bristles, or they can be placed thickest in
those parts most exposed to a bending or breaking strain, while in other parts they
can be less frequent, or absent altogether. I sometimes prefer however for
appearance sake to keep them entirely absent from the outside row of bristles.
I am well aware that wire cards have been used from time immemorial
for carding wool, that iron points have been put into electric hair brushes, into
combing brushes for horses, and the like, where it was desirable to cause a hard
scratch, but I believe never before until my Invention have practically incorrodible
flexible metallic bristles been used, mixed with other bristles in brushes used for
purposes where they may get wet.
I do not claim at all a purely metallic brush, but 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 :-
The improvement in brushes which consists in mixing with the ordinary organic
bristles or fibres ordinarily used, difficultly corrodible. flexible metallic fibres,
substantially as, and for the purposes described.
