PROVISIONAL SPECIFICATION.
Improvements relating to the Stretching and Drying of Hanks
of Yarn.
I, GATHORN ORMONDROYD, of Wibsey, near Bradford, in the County of
York, Mill Manager, do hereby declare the nature of this invention to be as
follows:
:-
This invention relates to improvements in apparatus for stretching hanks of yarn
for the purpose of taking the curl out of the yarn and to hold it perfectly straight
whilst it is dried, and its object is to provide a more convenient, accurate and
reliable apparatus than that generally in use.
For this purpose I employ a suitable framework having a longitudinal top girder
or carrier provided with bearings for a number of hank rollers which project
horizontally at right angles on each side. The bearings for the rollers are semi-
circular, or U shaped open at the top so that the rollers may each be lifted out and
placed on an adjacent bearing for the purpose of making a larger space between
the rollers and consequently allow the hanks of yarn to be more conveniently
placed upon or taken off the roller next to said space. The rollers are consecu-
tively placed in position to be filled and bearing brackets are provided at one or
both ends of the apparatus adapted to receive one or more of the end rollers whilst
the hanks are being put on or taken off adjacent rollers.
:
A lower set of rollers are provided mounted perpendicularly beneath the upper
rollers in similar bearings formed in an adjustable girder or longitudinal slide
capable of being moved vertically to apply the tension to the hanks. Two or more
screws are provided to effect this adjustment. These screws preferably engage
female screw threads in the adjustable girder and are mounted in bearings formed
in the top girder and are preferably rotated by worm wheels fixed upon them
engaging worms upon a horizontal shaft adapted to be turned by hand.
I
The rollers are each made with square or other sockets at their outer ends
adapted to receive a handle or key to turn them when required. They are also
each made with two collars to confine, them longitudinally and prevent the yarn
touching the framework.
An automatic gauge or measuring device is provided to indicate when the yarn
is stretched to the required extent. This measuring device may consist of a chain
or flexible band fixed by one end to the framework and passed under a pulley or
pulleys on the adjustable slide and then up into a convenient position to be seen
and the end is passed over a pulley on the frame and a weight or spring attached.
This chain carries a pointer or finger which travels over or past a measure or scale.
Instead of the chain a vertical rod may be used carrying a pointer which is prefer-
ably adjustable. Or a graduated rod or measure may be used in conjunction with
a stationary pointer.
In any case a device may be provided to ring a bell or give other audible
indication when the requisite tension is applied to the yarn.

of Yarn.
I, GATHORN ORMONDROYD, of Wibsey, near Bradford, in the County of
York, Mill Manager, 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 improvements in apparatus for stretching hanks of yarn
for the purpose of taking the curl out of the yarn and to hold it perfectly straight
whilst it is dried, and its object is to provide a more convenient, accurate and
reliable apparatus than that generally in use.
To fully describe my invention reference is made to the accompanying sheet of
drawings forming a part of this specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, is an elevation of my improved apparatus.
Figure 2, represents a plan of the same.
Figure 3, represents an end view of Figure 1 with a hank of yarn shown on one
Bide.
"
Figure 4, represents a cross section of the same on the line a, b Figure 2.
The end frames A, A 2 are connected together by the top girder B and the bottom
stay A 3. The girder B has a number of U shaped bearings B 3 formed in it open
at the top to receive bank rollers C which project horizontally at right angles on
each side. The rollers C may each be lifted out of its bearings and placed in
adjacent bearings for the purpose of leaving a larger space between the rollers and
consequently allow the hanks of yarn to be more conveniently placed and "dressed
upon the roller next to said space. The rollers C are consecutively placed in
position to receive the hanks of yarn and bearing brackets B2 are provided at both
ends of B to receive one or two of the end rollers whilst the hanks are being 'put
upon or taken off the adjacent rollers. The brackets B 2 are hinged to B and those
on the left hand end of Figure 1 are shown with two rollers C upon them, whilst
the brackets on the other end are shown turned up out of the way.
A lower set of rollers D are provided mounted perpendicularly beneath the
rollers C in bearings formed in the adjustable girder E the ends E 2 of which fit
between the guides A 4 formed in the end frames.
.
Vertical screws F confined longitudinally' between the bottom stay A 3 and the
girder B are provided.
These screws pass through nuts F 2 secured to E which nuts have female screw
threads fitting the screws. Worm wheels G fixed on the screws engage worms H
on the horizontal shaft H 2 and the ends H 4 of this shaft project and may be turned
by a winch handle to lower the rollers D to apply the tension to the banks
A pinion H5 is fixed to the shaft H 2 at each end and large spur wheels H3
which may be turned by a winch handle are provided at each end to engage said
pinions to enable the girder D to be more rapidly lowered or raised.
The rollers C are each made with square sockets C 2 at their outer ends adapted
to receive a handle or key by which to turn them when required when the hanks of
yarn are upon them. Both the rollers C and D are made with collars J to confine
them longitudinally and prevent the yarn touching the girders.
A gauge or measuring device is provided at each end to indicate when the yarr
is stretched to the required extent. These devices consist of a chain K passed round
the pulleys K 2 mounted upon the inside of the end frames. The ends K 3 of the
chains are secured to the girder E and a pointer K 4 is fixed to each of the chains.

page_text: A half inch scale L is mounted on the top of the girder across which scales the
pointers K 4 travel and indicate the length the hanks are stretched to.
A pillar A 6 (Figure 1) may be provided to support the centre of the girder B.
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. A hank stretching machine in which the upper rollers may be moved aside and.
which is constructed and arranged, substantially as herein shown and described, and
illustrated in the accompanying drawings.
2. The combination with a hank stretching machine of the hinged end brackets B2
for supporting the rollers substantially as herein shown and described.
3. The combination with a hank stretching machine of the measuring device,.
substantially as herein shown and described.
