Improvements in Finishing Yarns for Textile Purposes.
ALFRED HITCHON Globe Iron Works, Accrington Machine Fitter do hereby
declare the nature of this invention to be as follows:-
These improvements are to provide better means of applying sizing ingredients to
yarn fabrics, mainly in connection with the sizing box, wherein are used metallic
squeezing rollers in one or more pairs the lower roller is usually constructed of a
hollow cylindrical copper shell supported on blocks that are mounted on an iron
axle, the expanding of the said copper shell and the pressure of the top squeezing
roller which is made use of for squeezing away the surplus size is liable to sink the
shell of the lower hollow roller from its true cylindrical shape at parts betwixt the
blocks that gives it support, thereby causing inequality in squeezing away the surplus
size from the yarns which they draw betwixt the nip of their periphery. In conjunc-
tion with the first pair of the above described rollers there are other rollers made
use of for conducting the yarn from the reel or beams towards the liquid size the
revolving motion of these rollers and beams is derived from the drawing power of
the pair of squeezing rollers that is nearest to them thereby subjecting the sheet of
yarn to inequality of tension as it is being immersed into the size, thereby prevent-
ing an equal amount of the liquid size getting freely betwixt the twisted fibres of
each thread of yarn preparative to its being drawn betwixt the squeezing rollers.
The first portion of my improvement for giving better regularity of sizing finish
to twisted yarns is as follows. I give better support to the bottom squeezing roller
shells by filling up the hollow vacant parts with concrete cement or other like sub-
stances that will give a solidity of support betwixt the metallic blocks on which the
shell is mounted. This also serves as a preventative of fractional parts of the roller
shell that is not in direct contact with the blocks becoming overheated too quickly,
thereby expanding and straining the roller out of truth before its shafts could got the
heat to give uniformity in expansion.
I relieve the tension of the unsized yarn as it is being conducted into the boiling
liquid sizing also better than hithertofore for it being able to got more freely betwixt
the twisted fibres of the yarn by making (or providing) one or more of the unsized
varn conducting rollers into draw or pulling rollers so as to partly relieve the drawing
of the yarn by the size squeezing rollers to prevent the yarn from being strained
while it is saturated with size. I also provide means with those yarn rollers to take
up the slack yarn by the reels or beams over running by sudden stoppage of the
machine.

COMPLETE SPECIFICATION.
Improvements in Finishing Yarns for Textile Purposes.
ALFRED HITCHON of Globe Works Accrington in the county of Lancaster
Machine Fitter 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 :-
Fig. 1 is the elevation of plan view. Fig. 2 both marked in figures to correspond
alike in their detail parts. A portion of the upper side of shells of the two lower
size squeezing rollers is shewn as cut away to illustrate their insides as being filled
with concrete or cement as made use of for giving better support to their metallic

page_text: shells. On one of these lower size squeezing roller ends, marked C-Fig. 1-is shown
a chain driving pulley connected by a bar chain to a driven pulley on the end of
yarn drawing roller A to take action for taking part of the strain off the yarn as it
is being saturated in the size; for same like purpose at the opposite end of lower
size squeezing roller O which is better illustrated on Fig. 2 plan, is a spur driving
wheel D gearing to tooth wheel pinion E on the inner side of the first pair of adjust-
able expanding pulleys F which drive through an angle shapo belt (or rope) to a
similar pair of driven pulleys at G mounted in same like manner to the smaller pair
of size squeezing rollers H used in connection with the upper size box K. The
so-called term adjustable expansion pulleys marked F G and shown in separate section
at N are adjustable in their driving grooves to variable diameters for giving a
differential speed to the driven pair of pulleys and the belt in connection with
them, and when made use of betwixt the driving gearing of rollers, as illustrated, gives
an easy adjustment to their separate driving gearing, and when separate sheets of yarn
have to be drawn off the same beams for separate immersion in different kinds of
liquids the tonsion of each separate sheet as illustrated M and L can be equally adjusted
to prevent any of the threads of yarn being overstrained as it is being immersed.
The yarn drawing rollers such as A is shown as an assistant driving medium for
pulling round the reels or beams of yarn that are to be sized into size boxes of this
kind, as illustrated.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The driving of yarn drawing roller or rollers for the purpose of relieving the tension
or strain on the yarn prior or as it is is being saturated in the size.
2nd claim. Size squeezing rollers having the assistance of driven rollers with
driving pulleys as illustrated and described for same like purposes.
Dated this 24th day of October 1889.
