Improvements in the Manufacture of Drawing and Spinning Frame
Rollers.
I, JAMES PICKLES, of Laurel Street, Leeds Road, Bradford, in the County of
York, Machine Maker, do hereby declare the nature of this invention to be as
follows:
This invention relates to certain improvements in the manufacture of what are
commonly known as the front top rollers of drawing and spinning frames, and
has for its object the construction of such rollers, in a more simple manner than
hitherto, also in such a way that the rollers are either homogeneous throughout,
or of varying degrees of penetrability. Such rollers may be used with or without
a leather covering.
In carrying out my object, I form the rollers of paper pulp, preferably, such
as is prepared from long fibrous material, with the pulp may be mixed a small
quantity of adhesive substance such as linseed oil varnish, dissolved india rubber
or other suitable well known adhesive substance, or the outer surface only of the
roller may be coated with the same.
Should it be desired, however, to form a soft roller, I add to the above granu-
lated cork or other soft spongy material, in such proportions as is suitable to the
degree of softening required, to which may be added dissolved india rubber or
other suitable and well known adhesive, all of which are thoroughly mixed
together.
The pulp, or the compound for the soft rollers, prepared in the manner
described, is then placed into a mould of the form required with corresponding
form of cover, the material is then compressed by suitable means, such as a screw
or by hydraulic pressure, provision being made, in the mould, for the escape of
the surplus moisture in the pulp or compound.
After pressing the material to the consistency required, the rollers are taken
from the mould, allowed to set, placed upon the spindles and turned to the re-
quired diameters, by the first means rollers thoroughly homogeneous, and by the
second, rollers of varying degrees of penetrability are constructed, the same may
be covered with leather, or the turned circumference of the rollers brought into
direct contact with the circumference of the bottom rollers of the machine.
Dated this 23rd day of December 1897.

Roller:.
I, JAMES PICKLES, of Laurel Street, Leeds Road, Bradford, in the County of
York, Machine Maker, 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 certain improvements in the manufacture of what are
commonly known as the front top rollers of drawing and spinning frames, and
has for its object, the construction of such rollers in a more simple manner than
hitherto, also in such a way that the rollers are homogeneous throughout,
and may be made of varying degrees of penetrability. Such rollers may be used
with or without a leather covering.
In describing my invention in detail, reference is made to the accompanying
sheet of drawings in which Fig. 1 represents a plan of a mould suitable for con-
structing rollers in accordance with my invention, and
Fig. 2 is a section through same.
In carrying out my object, I form the rollers of paper pulp, preferably such as
is prepared from woollen, ground leather, hemp, jute or other suitable long fibrous
material, and with the pulp may be mixed a small quantity of adhesive substance
such as linseed oil, varnish, dissolved india rubber or other suitable well known
adhesive substance, in the proportion of 5 to 10 per cent., according to the required
hardness of the roller, the addition of the adhesive substance making the rollers
harder.
The pulp or compound for the rollers prepared in any convenient and suitable
manner, when mixed with say 10 per cent. of adhesive material produces a hard
homogeneous roller. The mixture is placed in a mould of the form required, such
as is shown by the drawings in which A represents the dish of the mould provided
with a loose bottom B arranged with a series of holes C through same for allowing
surplus liquid to escape. The pulp within the mould is covered by the lid D and
compressed by the tightening of bolts B or the necessary amount of pressure may
be obtained by placing the mould under a screw or hydraulic press, the surplus
moisture in the pulp or compound, escaping through the holes C in loose bottom B
and around the space E between the circumference of the mould and cover.
Should it be desired to mould the rollers with a hole in the centre, a spindle F
of the required diameter is placed in the mould, and after the material is pressed
in any suitable manner to the consistency required, the rollers are taken from the
moulds, allowed to set, placed upon the spindles and turned to the required
diameter.
By mixing the pulp in the manner described, homogeneous rollers having vary-
ing degrees of penetrability may be constructed; for hard rollers the mixture may
consist of 90 per cent. of pulp prepared from long fibrous material to which is
added 10 per cent. of adhesive substance; if what is known as a soft roller is
required, it may be obtained by mixing together 85 per cent. of pulp prepared
from long fibrous material 10 per cent. of granulated cork, granulated leather
or other like soft material and 5 per cent. of adhesive substance. A greater degree
of softness of the roller is obtained by increasing the proportion of granulated
leather, cork or the like, and decreasing the adhesive substance.
Rollers formed in the manner as before described may be covered with leather,
or the turned circumference of the rollers brought into direct contact with the
circumference of the respective bottom rollers.

page_text: Having now particularly described and ascertained the nature of my
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The construction of drawing and spinning frame rollers of paper pulp or paper
pulp mixed with granulated cork, leather or other like material mixed and com-
pressed in a mould, substantially in the manner as herein before set forth.
