Improvements in Yarn-dyeing Machines.
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 the class of yarn dyeing machines in which a wheel or
frame is arranged to rotate partly in and partly out of the vat containing the dye-
liquor, and is provided in its interior with bars on which the skeins of yarn to be dyed
are carried.
The invention consists in disposing the respective sets of yarn carrying bars in
planes oblique to the radius of the rotary dipping wheel or frame, whereby the
capacity of the latter of containing yarn is materially increased, and the skeins of
yarn are carried in such positions as to cause them to be drawn partly end wise and
partly sidewise through the dye liquor and thus the yarn is dyed more evenly and
without subjecting the same to the strain incident to the sagging of the between
the supporting bars, all as hereinafter more fully described and shown.

In the annexed drawing, Fig. 1 is a vertical transverse section of a dyeing machine
embodying the invention, a number of the yarn carrying bars being bare to show the
supports for the same on the wheel, Fig. 2 is a vertical longitudinal section on
line a, a, Fig. 1, and Fig. 3 is a detail view of the supports of the yarn carrying
bars.
Similar letters of reference indicate corresponding parts.
A represents the vat containing the dye-liquor. Horizontally across the centre of
the top portion of this vat and journalled in suitable bearings in the sides thereof is
the shaft a of the dipping wheel C consisting of two annular end plates b-b secured
to spiders D-D which are fastened to the aforesaid shaft. A pulley or gear wheel F
is attached to one end of said shaft to transmit motion thereto.
c-c denote the yarn-carrying bars which are arranged in sets or pairs, each of
which is disposed in a plane oblique to the radius of the wheel as shown in Figure 1
of the drawing. Various means may be employed for sustaining the bars of each set
or pair in the aforesaid planes and a proper distance apart to hold the skeins of yarn
which extend around them.
One of such means being represented in the form of parallel cleats d―d secured
to the inner sides of the annular plates b-b in lines oblique to the radius of the
wheel. The ends of the bars -c entering between said cleats and by means of
pins e e passing through the cleats at the inner side of the outer bar and at the
outer side of the inner bar said bars are retained the requisite distance apart.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents I declare that what I claim is :-
In a machine for dyeing yarn in skeins, the combination with the rotary dipping
wheel, of yarn supporting bars arranged in sets and each of said sets disposed in a
plane oblique to the radius of the wheel, substantially as set forth and shown.
