Improvements in Brushes.
I, WILLIAM HENRY CRAWCOUR, of Toynton Villa, William Road, West
Bridgford, in the County of Nottingham, Commission Agent, do hereby declare
the nature of this invention to be as follows:-
This invention relates to brushes employed for washing and scouring floors,
walls, woodwork and other objects and utensils, also tooth brushes, nail brushes,
and the like, and it has for its object improvements in such brushes so as to
make them more convenient to use and more effective.
In carrying out this invention the working face of the brush is preferably
formed by one piece of india-rubber moulded into longitudinal or transverse
V shaped corrugations or pleats, so as to form raised ridges alternating with
depressions both on its exterior and interior face.
The india-rubber which may be of any suitable size and shape, is enclosed by a
frame of wood or other suitable material the edges of the india-rubber, being
strengthened or conveniently formed so that they may be secured to the interior of
the said frame.
The frame is provided with a hinged or sliding top which may be formed of zinc
or other non-corrosible metal or the same material as the frame, against which the
interior raised ridges on the india-rubber rest and thus form a support for it at all
points.
Soft, dry, or other suitable soap or bits of ordinary soap, tooth powder or other
substances may be placed in the inner depressions in the rubber from time to time
as required by opening the top.
The india-rubber part is formed with perforations at suitable intervals and the
frame or lid with openings to admit the water which again works its way together
with a portion of soap or substance which the water will take up, through the said
perforations in the rubber as the brush is used, the action of the rubber
as the brush is used assisting the soap or substance, and water in the interior.
of the brush to mix and work out on to the object which is being cleaned.
One or both ends of the frame may be provided with suitably shaped india-
rubber projections or ordinary brushes formed of bristles, for getting into corners
or crevaces or depressions in the surface of the object on which the brush is
used.

I, WILLIAM HENRY CRAWCOUR, of Toynton Villa, William Road, West
Bridgford, in the County of Nottingham, Commission Agent, 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 relates more particularly to brushes used for washing and scouring..

page_text: floors, walls, woodwork, and other objects or utensils, but it may also be applied to
brushes for all kinds of work.
The invention will be best understood by reference to the accompanying
drawings,.in, which.:-
Fig. 1 is a side elevation, and
Fig. 2 an end elevation of a scrubbing brush constructed according to my
invention.
Fig. 3 is a plan showing the top removed, and
Fig. a vertical cross section, taken on line X X of Fig. 1.
Like figures indicate like parts throughout the drawings.
In carrying out this invention, the working part of the brush is preferably formed
by one piece of india-rubber or composition, A, moulded on the exterior with
raised ridges B alternating with spaces C, the said ridges B and intervening
spaces C being preferably made in the form shewn,
The raised ridges B and spaces C, may be arranged longitudinally as shown or
transversely or obliquely according to the direction in which the brush is to be
mainly reciprocated when in use.
The interior of the india-rubber or composition working-part A. (see Figure 4.)
approximates in form to the exterior, raised ridges D alternating with spaces E;.
the ridges D on the interior preferably correspond to the position of the spaces C
on the exterior, and vice versa as shown, the walls of india-rubber or composition
being thus parallel.
The ends of the interior spaces E are closed at the ends by webs F (see Fig. 3.)
so that they form receptacles for soft, dry, or other soap, tooth powder, or other
substances, which work through perforations G. to the exterior when the brush is
in use.
The upper part of the india-rubber or composition working part A. is secured in
a frame H. formed of wood, or other suitable material, for instance, of metal, by
rivets I. or other suitable means; this frame may be strengthened and the india-
rubber supported by cross stays J. The frame H is also provided with a hinged
or sliding lid or top K so as to form a ready means of access to the interior, in
which the soap or other substance is placed.
The lid K or frame H may be formed with one or more openings to admit
water into the interior of the brush, which water again works its way out
through the perforations G. together with a portion of the soap or substance
in the interior which the water will take up, the bending action of the india-
rubber or composition parts, as the brush is used, assisting this process.
The ends B₁ of the exterior raised ridges B may be extended as shown
beyond the frame H in order that the brush may be effectively used in corners,
crevices or depressions in the surface of the object on which the brush is used.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is:
:
-
1: In a brush the formation of the india-rubber or like working part A with
exterior and interior raised ridges such as B and D, alternating with intervening
spaces such as C and E, substantially as described.
2. In a brush the formation of the india-rubber working part A with exterior
and interior raised ridges such as B and D, alternating with exterior and interior
spaces such as C and E, the said spaces E being closed at the ends by webs F
80 as to form receptacles for soap or other substance, and the walls perforated to
permit of its gradual escape substantially as described.
3. In a brush, the combination with an india-rubber working part A, formed
with exterior and interior raised ridges, such as B. and D. alternating with
intervening spaces such as C and E, of a frame, such as H. provided with a lid K.
substantially as described.

page_text: 4. The combination and arrangement of parts constituting the complete brush
substantially as described and illustrated in the accompanying drawings.
