PROVISIONAL SPECIFICATION.
Improvements in Securing or Mounting Shells of Metal Squeezing
Rollers on their Blocks and Shafts to be made Use of in
Squeezing Yarn.
THOMAS LIVSEY ORMEROD Clough End Mill Haslingden Cotton Manufacturer, and
ALFRED HITCHON, Globe Iron Works, Accrington, Machine Fitter, do hereby declare
the nature of this invention to be as follows :-
--
The object of this invention is to improve the Mounting of Motal Shells on
Squeezing Rollers (such as are commonly made use of in connection with Sizing
Machines and Sow boxes to squeeze out from the yarn the surplus size).
In the rollers at present in use the heat from the boiling size causes the outward
metallic shell of the roller to expand differently from the central shaft on which the
shell is firmly fixed thereby causing an unequal strain on the shell which throws it
out of truth. To obviate this we propose to mount the external shell in such a way
as to give it free longitudinal expansion. To obtain this the block ends supporting
the shell are mounted on an axle which is in two separate parts so that each part is
free to move outward with the expansion of the shell. For convenience and better
support of the inner ends of these axles we may make use of extra inner blocks or socket
supports, which will allow the inner ends of the shaft to slide loosely apart from each
other. As a modification for the same purpose.
As we find convenient the roller
axle may be made as in one piece, but bent out of parallell position with the roller
shell, either in a special form or made up of slender crooked metal rods, serving as an
expansion disc, which may be used to give the roller axle the necessary expansion we
require to serve its giving way to suit the roller shell.

COMPLETE SPECIFICATION.
Improvements in Securing or Mounting Shells of Metal Squeezing
Rollers on their Blocks and Shafts to be made Use of in
Squeezing Yarn.
THOMAS LIVSEY ORMEROD, Manufacturer, Clough End Mill, Haslingden and
ALFRED HITCHON, Machinery Salesman, Globe Iron Works, Accrington 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:--
Figure 1 illustrates the section of a metal roller (such as is commonly made use of
in connection with sizing machine sow boxes, to squeeze out from the yarn the
surplus size). Our improvement to same is shewn at parts marked 2-3 and 4.
2 and 3 are the inner ends of the roller axle brought nearly together in a coupling
block that is suitable for a bearing to keep the axle ends in a central position to the
roller shell, also providing the necessary loose sliding endways of the axles for
expansion of the roller shells that are mounted on the outer block ends that may be
secured to the axles; the centre block or coupling 4 is not secured to the two axle
ends. Fig. 2 is similar to Fig. 1but minus flange on the coupling 4.
Fig. 3 illustrates the roller axles as made with slender rods to form the necessary
expansion disc. Fig. 4 illustrates the centre of the axle bent in a spiral form for same
like purpose.

page_text: 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 our
claim is
The mounting or securing shells of metal squeezing rollers on axles made in two
or more parts as a provision for the expansion of their metal shells being expanded
by heat, or with flexible axles as illustrated for same like purpose and set forth by
the accompanying drawings.
