PROVISIONAL SPECIFICATION.
Improvements in Metal Rollers employed in Yarn Sizing and other
Machines in which they are Subjected to Extreme Variations of
Temperature.
I, THOMAS WINTER, of Perseverance Works, Byrom Street, Blackburn, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention to
be as follows:—
This invention relates to the copper rollers mainly used in the sizing of yarn and
consists of improved means and appliances employed for mounting such rollers upon
their axis or carrying shaft so as to provide for expansion and contraction of the
shell or roller longitudiually; the invention being applicable generally to metal
hollow rollers subjected to extreme variations of temperature.
According to this my invention I attach one end of the roller shell by flange
screwed boss and screwed shaft and pin as ordinary, such I style the "fast end,"
of the roller mounting. The other end and improved mounting comprises a flanged
screwed boss continued and extended in the form of a tapered boss its internal
diameter or bore being conical or tapered within which boss is received two or more
(preferably three) segments of a hollow cone forming a bush in which the enlarged
part of the shaft is received the outer diameter of the bush being conical to
correspond with the interior or bore of the conical boss a metal ring or washer is
passed along the shaft and rests against the ends of the segments referred to, next
there is a spiral spring placed on the shaft and that is followed by a second metal
ring or washer upon which is stuffing or padding-viz. of asbestos (or other like
material) followed by a screwed plug or gland chased on its outer shoulder so as to
be screwed into and capable of movement along with the screwed boss first mentioned
upon the shaft or axis.
The roller shell is thus mounted upon its carrying shaft, that one of its ends is
free, and thus the roller is free to expand and contract along its shaft, the segmental
bush provides a sufficient bearing for the shaft inside its mounting and at all times
provides for wear or change of position on the shaft of such mounting, the spiral
spring acts to return the segments on contraction whilst the asbestos, glands
and fittings as herein described excludes size or liquid from the interior of the
roller.

COMPLETE SPECIFICATION.
Improvements in Metal Rollers employed in Yarn Sizing and other
Machines in which they are Subjected to Extreme Variations of
Temperature.
I, THOMAS WINTER, of Perseverance Works, Byrom Street, Blackburn, in the
County of Lancaster, Machinist, 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 copper rollers mainly used in the sizing of yarn, and
consists of improved means, and appliances employed for mounting such rollers
upon their axis, or carrying shaft so as to provide for expansion, and contraction of

page_text: the shell, or roller longitudinally; the invention being applicable generally to metal
hollow rollers subjected to extreme variations of temperature.
According to this my invention I attach one end of the roller shell by flange,
screwed boss, and screwed shaft, and pin as ordinary, such I style the "fast end,"
of the roller mounting. The other end, and improved mounting comprises a
flanged screwed boss continued and extended in the form of a tapered boss, its
internal diameter, or bore being conical, or tapered. Within such boss is received
two or more (preferably three) segments of a hollow cone forming a bush in which
the enlarged part of the shaft is received the outer diameter of the bush being
conical to correspond with the interior or bore of the conical boss. A metal ring,
or washer is passed along the shaft and rests against the ends of the segments
referred to, next there is a spiral spring placed. on the shaft, and that is followed
by a second metal ring or washer upon which is stuffing or packing is, of asbestos
(or other like material) followed by a screwed plug, or gland, chased on its outer
shoulder so as to be screwed into, and capable of movement along with the screwed
boss first mentioned upon the shaft, or axis.
The roller shell is thus mounted upon its carrying shaft that one of its ends is
free, and thus the roller or shell is free to expand and contract along its shaft.
The segmental bush provides a sufficient bearing for the shaft inside its mounting
and at all times provides for wear or change of position on the shaft of such
mounting, the spiral spring serving to return the segments on contraction whilst the
asbestos, glands, and fittings as herein described exclude size or liquid from the
interior of the roller.
Such being the nature and object of my invention the following is a complete
description of same, reference being had to the accompanying drawings in which
Fig. 1 is a longitudinal sectional elevation of a size roller having my improvements
applied thereto.
Fig. 2 is a detail of a slightly modified form of roller end drawn to enlarged
scale.
Fig. 3 is a section on line A. B of Fig. 2.
According to this my invention 1 attach one end of the roller shell 1 by flange
screwed boss 2 and screwed shaft 3 and pin as ordinary, such I style the "fast
end, of the roller mounting and this is illustrated at the left hand side of Fig. 1.
The other end and improved mounting comprises a flanged screwed boss 4
continued and extended in the form of a tapered boss 5 its internal diameter or
bore 6 being conical or tapered and within such boss 5 is received two or more
(preferably three) segments 7 of a hollow cone forming a bush in which the
(preferably enlarged part of the) shaft is received (see Fig. 2) the outer diameter
of the bush 7 being conical to correspond with the interior or bore 6 of the conical
boss 5, a metal ring or washer 8 (see Fig. 2) is passed along the shaft 3 and rests
against the ends of the segments 7 referred to, next there is a spiral spring 9 placed
on the shaft, and that is followed by a second metal ring or washer 10 upon which
is stuffing, or packing viz. of asbestos (or other like material) 11 followed by a
screwed plug, or gland 12 chased on its outer shoulder so as to be screwed into,
and capable of movement, along with the screwed boss 4 first mentioned, upon the
shaft or axis 3.
The roller shell is thus mounted upon its carrying shaft 3 that one of its ends
is free, and thus the roller also is free to expand, and contract along its shaft 3,
the segmental bush 7 provide a sufficient bearing for the shaft 3 inside its mounting,
and at all times provides for wear, or change of position on the shaft 3 of such
mounting, the spiral spring 9 serving to return the segments 7 on contraction,
whilst the asbestos 11, glands, and fittings as herein described exclude size, or liquid
from the interior of the roller. At 13. 13. are keys, the one on the loose end of
the roller working in a key bed, provided for the purpose of preventing the flanges,
and shell of the roller, turning or moving circumferentially on the shaft 3 but at
the same time allowing longitudinal expansion.
In Fig. 2. are shewn the metal rings or washers 8-10, and in Fig. 1. one of the

page_text: rings is dispensed with one end of the spring abutting against the segments 7 and
the other end against the metal ring or washer 10; and also a modified method of
fixing the screwed plug or gland 12 which in Fig. 1. is shewn fastened by set
screws, and in Fig. 2 screwed into position.
When the heat begins to expand the copper tube or shell 1 the first effect is for
it to push upon the ends, or flanges 2-4 and to attempt to force them outwardly.
This action with regard to the Hange 4 is aided by the spring which constantly
keeps the split bush in position so as to enter the tapered boss, and aid in driving
it. This action however, entirely avoids any danger of the buckling, or bending of
the copper cylinder. When the cylinder contracts it draws in the flange 4 and its
attached plug or gland 12 and again compresses the spring 9. This freedom of
movement has been found of great service, and after some months of work, rollers
of this construction are practically as good as new. In addition to the advantage
thus gained there is an auxiliary advantage arising from the fact that the shaft is
entirely protected from absolute contact with the size, and any corrosion of it thus
rendered impossible. This is ensured by the two brass bushes, or collars 14 which
are shewn at each end of the roller in Fig. 1.
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 construction, and arrangement of parts applied to, and in combination with
the axes of hollow metal cylinders for purpose of providing for expansion and
contraction, and as such parts are herein fully described, and substantially as
illustrated by drawings annexed.
