PROVISIONAL SPECIFICATION.
Improvements in Brushes.
I, SAMUEL ABRAHAM of Cleveland, United States of America but now
residing at No. 89, Rue de la Consolation, Brussels, Belgium, do hereby declare
the nature of this invention to be as follows:-
My invention has reference to improvements in brushes of the kind employed for
scrubbing floors of various kinds as for examples parquetry floors and tiled or
flagged floors, and also for cleaning troughs or vats employed in certain industries,
as for examples the cooling vats, mash tuns, and fermenting vats used in breweries.
According to this invention the brush constructed with tufts of horsehair or
fibres as usual, is furnished with one or more bands, strips or sheets (hereinafter
called strips) of caoutchouc or india rubber fixed at one edge in a groove or grooves
in the backing or mount of the brush, or against the edges of the brush in the
direction of its length and in such a manner that the opposite or free edge or side
of the strip will extend to the level or nearly so of the free ends of the tufts of
horsehair or fibres with which the brush is furnished.
Instead of strips of caoutchouc, there may be employed in certain cases, strips
of felt or other analogous material.
In using the improved brush, the strips of caoutchouc or felt act to drive away
the washing water or liquid with which it is used and which can only be driven
away in an incomplete manner by the horsehair or fibres of the brush between
which it can partly pass. Thus by the combined action of the tufts of horsehair
or fibres and of the strip or strips of caoutchouc or felt, there can be obtained a
far quicker and more effective cleansing action than with brushes as ordinarily
constructed.

COMPLETE SPECIFICATION.
Improvements in Brushes.
I, SAMUEL ABRAHAM, of Cleveland, United States of America, but now
residing at No. 89, Rue de la Consolation, Brussels, Belgium, 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 has reference to improvements in brushes of the kind employed for
scrubbing floors of various kinds as for examples parquetry floors and tiled or
flagged floors, and also for cleaning troughs or vats employed in certain industries,
as for examples the cooling vats, mash tuns, and fermenting vats used in
breweries.
According to this invention the brush, constructed with tufts of horsehair fibres
or wires as usual, is furnished with one or more bands, strips or sheets (bereinafter
called strips) of caoutchouc or india rubber fixed at one edge in a groove or grooves
in the backing or mount of the brush, or against the edges of the brush in the
direction of its length and in such a manner that the opposite or free edge or side
of the strip will extend to the level or nearly so of the free ends of the tufts of
horsehair or fibres with which the brush is furnished.
In using the improved brush, the strips of caoutchouc or felt act to drive away

page_text: the washing water or liquid with which it is used, and which can only be driven
away in an incomplete manner by the horsehair or fibres of the brush between
which it can partly pass. Thus by the combined action of the tufts of horsehair
or fibres and of the strip or strips of caoutchouc or felt, there can be obtained a
far quicker and more effective cleansing action than with brushes as ordinarily
constructed.
The annexed drawings illustrate two arrangements of brush according to my
invention.
Figs. 1 and 1 are end and side elevations respectively of a brush to which there
is applied a strip of caoutchouc fixed in the middle of the ordinary tufts of bristles
or fibres.
Figs. 2 and 2 are similar views of a brush having two strips of caoutchouc, one
applied against each of the longer sides of the backing to which both are attached
by means of a strip of metal fixed to the brush by screws.
In these figs., a is the ordinary wooden mount or backing; 6 the ordinary tufts
of bristles or fibres, and c the strips of caoutchouc fixed either in the grooved in
the backing a (Fig. 1), or by means of strips e of metal and by screws (Fig. 2ª)
against the longer sides of the said backing a.
In the side elevation, Fig. 1A, a portion of the tufts on the left hand side of the
figure are omitted with the object of more clearly showing the strip of
caoutchouc c.
The strips of caoutchouc c c instead of being fixed to the sides of the backing
by metal plates and screws as shewn in Figs. 2 and 24 may be fixed in grooves
formed close to the longer edges of the backing a so as to have one or more rows
of tufts of bristles between the strip of caoutchouc and the edge of the backing or
mount as will be readily understood without drawings.
Instead of caoutchouc strips of felt or analogous material may sometimes
be used.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A brush provided not only with fibres bristles or wires as usual but also with one
or more strips of material such as caoutchouc, felt, or the like fixed at one edge
within a groove or grooves formed in the backing of the brush or against the sides
of such backing and so that the opposite or free edge of the strip or of each strip
will extend to or nearly to the level of the free ends of the fibres, bristles or the
like of which the brush is composed substantially as hereinbefore described and
shown in the drawings annexed for the purpose specified.
