Improvements in or relating to Stretching Frames for Hanks or
Skeins of Yarns or the like in Mercerising, Bleaching, Dyeing,
and like Operations.
I, WILHELM HERSCHMAN, Manufacturer, of Paniglasse No. 9, Vienna IV,
Austria, 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:-
The present invention relates to stretching frames for hanks or skeins of yarn
or the like for bleaching, mercerising, dyeing and like purposes, each frame com-
prising two bars adjustable relatively to each other, over which the hanks or
skeins are placed, one or more of such frames being immersed in a receptacle
containing the water potash or other lye, dilute acid, dye, bleaching liquid or the
like, and rotated therein.
A convenient form of apparatus, especially suitable for this purpose is repre-
sented in the accompanying drawing:-
Figure 1 being a front view, partly in section, of a mounted frame, and
Figure 2 a plan view of same.
On a central vertical shaft b are arranged two discs a a keyed or fast on the
shaft and provided with a series of holes i corresponding with each other, and
serving for the attachment of the various frames e f c c.
The frame is intended for the reception and stretching of the yarn and
consists of two radially arranged rods e provided with screw threads, and two ver-
tically arranged bars e f, of which the bar cis hollow and is rigidly connected
with the radial bars c, while the outer bar f is adjustably arranged on the spindles c
it being provided with holes through which the spindles pass.
The material to be operated upon is placed around the two vertical bars ef,
after which the adjusting nuts h are turned on the spindles c until the yarn is
suitably stretched or held on the bars. The tubular bar e of the frame, thus
provided with the yarn, is then placed between the two discs a a and secured by
passing a bolt g through it, and two corresponding holes of the discs a.
On turning the central shaft 6 the arms f tend to move outwards owing to
the effect of centrifugal force by which means the yarn d is suitably stretched.
The removal of the yarn is carried out by operating in a reverse manner.
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 :-
1. Apparatus for stretching skeins or hanks for mercerising, bleaching, dyeing
and like purposes comprising two discs arranged on a central shaft between
which frames for the skeins or hanks are radially secured, the outer arms of
the frames being adjustable on the radially arranged bars provided with adjusting
nuts and screw threads and rigidly connected with the inner arms whereby the
yarn is suitably stretched owing to centrifugal force acting on the apparatus
whenever the latter is rotated, substantially as described.

and like purposes substantially as described or illustrated in the accompanying
drawings.
