PROVISIONAL SPECIFICATION.
Improvements in Rotary Knife Cleaning Machines.
I, JOSEPH WILLIAM SUTTON, of 199, 200 and 201 High Holborn, in the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
My invention relates especially to india rubber backing for the brushes or
rubbers of rotary knife cleaning machines and the object of the invention is to give
to the brushes or rubbers an efficient and durable elasticity much in excess of
that which they possess when the backing is hollow or tubular in form and such as
to render it impossible for the brushes to go flat.
The improved india rubber backing is solid and it is formed by rolling up
tightly upon itself in a transverse direction a band of prepared rubber so as to
form a close spiral roll. A narrow margin along one edge of the band is left
unrolled to form a tongue for fixing the backing. A tape of woven fabric is
cemented to the tongue on the inner side, it serves to secure the roll, around which
it extends over about a quarter of the circumference. The backing so prepared is
vulcanised.

In order that my invention may be fully understood I will proceed to describe
the drawings hereunto annexed.

The solid backing pieces are held in position by wooden distance pieces e fixed
upon the disc c.
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 1
claim is :-
Making the backing pieces for the brushes of a knife cleaning machine
substantially as described of a band of india rubber tightly rolled upon itself.
