PROVISIONAL SPECIFICATION.
Improvements in Metal Rollers for use in Hot Liquids, specially.
applicable to Rollers for the Size Boxes of Tape or Slashing
Warp Sizing Machines.
I THOMAS PARKINSON of Britannia Works, Canterbury Street, Blackburn,
Lancashire Iron and Brass Founder do hereby declare the nature of this invention.
to be as follows:---
This invention consists of improvements in the construction of rollers for the-
size boxes of tapes or slashing machines and is applicable to all rollers working in
hot liquids.
At present these rollers are made with a wrought iron shaft through the centre
carrying ends upon which the metal shell or roller is firmly secured and screwed by
means of a nut.
In my invention the ends of roller are left open and the roller is made as
follows:-
A strong centre shaft carries four or more pulleys or stays upon which is mounted
a shell to form the roller. This shell is fitted with a fast key at each end working-
into suitable slots in the outside stays, this prevents the roller from slipping and
allows the shell to expand and contract freely. The arms of the stays are formed
like the blades of a screw propeller and cause the size to flow through the roller
from end to end thoroughly agitating the size. By this invention perfect expansion
and contraction is attained and the collapse of roller shells prevented. The
materials of which the rollers are made can be varied to suit different requirements...

COMPLETE SPECIFICATION.
Improvements in Metal Rollers for use in Hot Liquids, specially-
applicable to Rollers for the Size Boxes of Tape or Slashing
Warp Sizing Machines.
I THOMAS PARKINSON of Britannia Works Canterbury Street Blackburn in
the County of Lancaster Iron and Brass Founder 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 consists of improvements in metal rollers for use in hot liquids-
specially applicable to rollers for the size boxes of tape or slashing warp sizing
machines.
Hitherto these rollers have been made with a wrought iron shaft through the-
centre carrying solid ends upon which the metal shell or roller is secured and
screwed by a nut thus permanently closing each end. In my invention the ends of
roller are left open and the roller is made as follows:-
A strong centre shaft carries four or more open stays upon which is mounted a
shell to form the roller. This shell is secured to the stay at each end which.
prevents the shell or roller from slipping and allows the shell to expand and
contract freely. The arms of the stays are formed like the blades of a screw
propeller and cause the liquid or size to flow through the roller from end to end
thoroughly agitating the size or liquid. By this invention equal expansion and
contraction is attained and the collapse of roller shells prevented. Such being the-

page_text: nature and object of this my said invention the following is a complete description
of same reference being had to the accompanying drawing in which
Fig. 1 is a complete section of roller.
A is the strong shaft carrying the stays.
B is the metal shell.
C. C. C. C. C. are the stays with arms in the form of screw propellers which
force the liquids or size through the roller and cause thorough agitation and equal
expansion.
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 :-
:-
1. The adoption of open ends for rollers through which liquids or size may flow.
2. The use of propeller stays which agitate the liquids or size and force them
through the roller causing the shaft and shell to expand equally.
