PROVISIONAL SPECIFICATION.
Improvements in Rubbers for Carding Engine Condensers..
I, ARTHUR HARDWICK, of Mount Terrace, Heckmondwike, in the County
of York, Overlooker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the manufacture of rubbers of
condensers for carding engines; the object being to make such rubbers of uniform
thickness, and practically of uniform texture, also more pliable, durable, and
effective than heretofore; and the invention consists in adding to, and combining
with the ordinary leather condenser rubber, a thin sheet of leather made pliable
by being cut into strips, or perforated, or scored, so that the inside portion, which
is at right angles to the outside, causes the whole, rubber to be more pliable and
yet stronger.
According to this invention, I employ an ordinary leather condensing rubber,
inside aud at right angles to the length of which I glue or cement a series of
strips of leather or other material, parallel to and nearly touching one another.
Or in lieu of the above, I employ a single sheet of leather scored or grooved at
intervals, or a sheet with a number of cuts close together at right angles to the
rubber, or a perforated sheet of leather; in each case the inner leather is rendered
more pliable by cutting, scoring, or perforating, so that whilst adding to the strength,
it does not detract from its pliability.
This improved method of building up a rubber makes one that is flexible, solid,
and with a straight, and even rubbing surface, and prevents the rubber from wearing
soft, flabby, or wavey.

I, ARTHUR HARDWICK, of Mount Terrace, Heckmondwike, in the County
of York, Overlooker, 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 to improvements in the manufacture of rubbers of
condensers for carding engines; the object being to make such rubbers of uniform
thickness and practically of uniform texture, also more pliable, durable, and
effective than heretofore, and the invention consists in adding to and combining
with the ordinary leather condenser rubber a thin sheet of leather made pliable
by being cut into strips, or perforated, or scored, so that the inside portion which

yet stronger.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being made to the accompanying drawings,
in which :-
Figs. 1, 2, 3, and 4 are views of the insides or backs of portions of improved
rubbers made in accordance with this invention.
Figs. 1^, 24, 34, ànd 4^ are edge views of Figs. 1, 2, 3, and 4 respectively.
According to this invention, I employ an ordinary leather condensing rubber 1
inside and at right angles to the length of which I glue or cement a series of strips
of leather or other material 2 parallel to and nearly touching one another
(see Figs. 1 and 14). Or in lieu of the above, I employ a single sheet 3 of leather,
scored or grooved at intervals 4 (see Figs. 2 and 24); or a sheet 3 with a number
of cuts 5 close together and at right angles to the rubber 1 (see Figs. 3 and 3^);
or a perforated sheet of leather 6 (see Figs. 4 and 44) cemented to the back or
inside of the rubber 1. In each case the inner or back leather is rendered more
pliable by cutting, scoring, or perforating, so that whilst adding to the strength, it
does not detract from the pliability of the finished rubber.
This improved method of building up a rubber makes one that is flexible, solid,
and with a straight and even rubbing surface, and prevents the rubber from wearing
soft, flabby, or wavy.
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 :-
The improvements in rubbers as herein described and substantially as illustrated
by the annexed drawings.
Dated this 10th day of February 1897.
