An Improved Covering for Spinning Rollers.
I, ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, do hereby declare the nature of this Invention to be as
follows:-
This Invention has for its object an improved covering for the pressure rollers
used in spinning.
The rollers made according to this Invention are perfectly cylindrical and without
joints, do not slip upon the axle, and offer all the required hardness. The result is,
therefore, better work, less wear and tear, and an economy in moving power.
Said result is obtained by applying to the axis of each roller, a facing of carded
cotton, or like material, which is laid on in sheet form, and then silicated, or treated
with a substance analogous to a silicate, and producing the same results.
The rollers ordinarily employed in textile industries are composed:
1. of a first facing of cloth, known as "Mulhouse," glued, and
2. of leather (generally calf) laid on by means of an apparatus forming a funnel.
Notwithstanding all the care taken in this manufacture, the joint of the cloth, and
that of the leather, exist always. These two joints are liable to injure the good
working of the machines and tend to cause cuts or slits in the spun goods.
These inconveniences are obviated in the following manner :-
The so called axis or roller is coated with glue, and is rolled upon a sheet of carded
cotton which adheres thereto.
The roller thus obtained is then rolled between three other rollers to bring, to the
thickness desired, the roller in course of manufacture. At the same time it is
impregnated with, or caused to imbibe, silicate of soda, so as to give to the manufac-
tured roller a certain varnish and a sufficient consistency for working.
The silicate of soda, in this operation, serves as a varnish and as an agglomerant,
but for it, there may be substituted any other suitable substance which would effect
the same object.
As before stated, the rollers thus made are perfectly cylindrical and do not present
any joint. As they cannot slip on their axle, it therefore follows that the weight of
pressure usually employed can he considerably reduced, and the effect is, therefore,
less wear and tear, and a considerable economy in moving power.

An Improved Covering for Spinning Rollers.
I, ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, 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, that is to say :-
This invention has for its object an improved covering for the pressure rollers used
in spinning.
Pressure rollers made according to this invention are perfectly cylindrical and
without joint or junction, do not slip upon the axle, and offer all the required hardness
and durability. Hence the result is better work, less wear, and an economy in motive
power.

The rollers ordinarily employed in the textile industry are composed, 1st, of a first
facing or covering of cloth known as Mulhouse," which is glued on, & 2nd, of
leather (generally calf) strained or laid on by means of a funnel-like apparatus.
Notwithstanding all the care taken in this manufacture the joint or junction of the
cloth and that of the leather always exist. These two joints or junctions are liable to
injure the good working of the machines and tend to cause cuts or slits in the span
goods.
These inconveniences are now obviated in the following manner :
The axis or roller proper is first coated with glue, or cement, and is then rolled upon
a sheet of carded cotton which adheres thereto. The cylinder thus obtained is next
rolled between three other rollers or cylinders so as to bring the roller in course of
manufacture to the required thickness. At the same time this roller is impregnated
with, or caused to absorb, silicate of soda, so as to give to the manufactured roller a
certain varnish and a sufficient consistency for working.
The silicate of soda serves, in this operation, as a varnish and an agglomerate,
but it may be substituted by any other suitable substance producing the same
effect.
The rollers thus manufactured are perfectly cylindrical and do not present any joint
or junction. As they cannot slip upon their axle it therefore results that the weight
of pressure usually employed can be considerably reduced, and the effect is conse-
quently less wear and tear and considerable economy in motive power.
Having now particularly described the nature of the Invention and in what
manner the same may be carried into effect J claim, as communicated to me by my
foreign correspondent:
The improved covering for spinning rollers, characterized by the application of
carded cotton, or other analogous material, glued or cemented on to the axis, then
impregnated or treated with silicate of soda, or other like substances producing the
same effect, substantially as herein before described and for the purpose set forth.
Dated this 13th day of January 1890.
