IMPROVEMENTS IN THE METHOD OF COVERING ROLLERS FOR SPINNING, DOUBLING AND DRAWING MACHINES
Year: 1884

both of Bentham in the County of York, Rubber Manufacturers and Dealers, do
hereby declare the nature of said invention for IMPROVEMENTS IN THE METHOD
OF COVERING ROLLERS FOR SPINNING, DOUBLING AND DRAWING MACHINES to be
as follows:-
This invention relates to certain improvements in the method of covering rollers
for spinning, doubling and drawing machines.
Hitherto rollers for the above purpose have been covered in the first place with
felt jointed with cement, and over this a covering of leather also jointed with
cement. The felting acts as a cushion for the leather covering, and yields on
In our improved method of covering, we encircle the roller with
a jointless rubber hoop, tempered by the process of vulcanizing to correspond with
the yielding of the felt in close contact with the body of the roller and the rigidity
of the leather on the outer surface of the same.

•
In leather coverings the wear and tear is very considerable, having to be
frequently recovered; another drawback to the leather covering is the oil from the
yarn gets into the pores of the leather and collects from the yarn some of its
substance called " flough " In our improvement a clean hard polished and
jointless surface is presented to the yarn, and the constituency of the rubber is so
mixed as also to present an oil resisting surface, for a depth say of one eighth of an
inch or more if desirable, whilst below this by means of tempering, the rubber is
soft and elastic.
The wear and tear to which rollers, covered by our improved method can be
Bubjected is far in excess of that of leather covered rollers, and in time it may be
necessary to restore an even surface to the face of the rubber covered rollers, which
are tempered not only.to stand the heat of the spinning room, but also to stand
the grinding by emery again to a smooth surface, and when the upper or hard
tempered portion is worn away the old rubber has a greater value than old leather.
We are aware that rollers have been covered by rubber of a homogeneous nature
throughout, and in consequence, such coverings have failed as an efficient substitute.

DI PULTIVATION
We JOHN QUINLAN, of Baines Great House, and GEORGE. CARR, of Bank View,
both of Bentham, in the County of York, Rubber Manufacturers, and Dealers, do
hereby declare the nature of our invention for "IMPROVEMENTS IN THE METHOD
OF COVERING ROLLERS FOR SPINNING, DOUBLING AND DRAWING MACHINES 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 certain improvements in the method of covering rollers
for spinning, doubling and drawing machines.
+
Hitherto rollers for the above purpose have been covered in the first place with
felt sewn or jointed with cement, and over this a covering of leather also sewn or
jointed with cement. The felting acts as a cushion for the leather covering and
yields on pressure.
In our improved method of covering, we encircle each roller with a jointless
rubber hoop, tempered by the process of vulcanizing to correspond to the yielding
of the felt in close contact with the body of the roller, and for a certain distance
from the outer surface of the jointless hoops they are left hard or rigid to correspond.
to that of leather..
With leather coverings, the wear and tear is very considerable the leather having
to be frequently renewed, whilst another drawback is, the oil from the yarn gets
into the pores of the leather and collects from the yarn some of its substance
called "flough" By our improvement a clear, hard, polished and jointless surface
is presented to the yarn; and the consistency of the rubber is so mixed by leaving
the circumference hard, that an oil resisting surface is obtained for a depth from
the circumference of say one eighth of an inch or more if desirable, whilst below
this the remainder of the rubber is rendered soft and elastic by means of tempering,
by subjecting the interior of the rubber hoops to the process of vulcanizing.
The wear and tear to which our improved roller coverings can be subjected is
far in excess to that of leather, because when the surface of our coverings becomes
rough, an even and smooth surface can be restored: the rubber being so hard, that
it will not only stand the heat of the spinning room but also the grinding down to
a smooth surface with an emery wheel of the ordinary construction.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
Covering rollers with jointless hoops of rubber tempered so that the same are
hard for a certain depth from the circumference, and the remainder of the rubber
soft and flexible for the purpose hereinbefore described.
