Improvements in Hank-dyeing Machines.
1, RICHARD GEE, of New Hay Road, Lindley near Huddersfield Yorkshire, Engineer
do hereby declare the nature of this invention to be as follows:-
This invention refers to hank dyeing machines and consists in the method of and
ineans for subjecting hanks of yarn to the action of dye liquor for the purpose of
producing an even and level colour, shade or tint upon the yarn throughout its
entire length so that one portion thereof shall not be lighter or darker than another
portion, or otherwise unequally dyed.
In order to carry out my invention I employ two suitable frames for supporting the
bobbins or creels which are to hold the hanks of yarn, one series of bobbins being
mounted in bearings on the upper frame and a corresponding series mounted in self
adjustable bearings on the lower frame, the two said frames being connected together
by a suitable arrangement of levers or levers and links, which, when operated by a
cam or its equivalent, cause the lower frame to be raised or to advance towards the
upper frame, and this is done as the said cam revolves.
The axis carrying the bobbins or creels on the upper frame are connected or
geared together by a train of toothed wheels so that when rotary motion is coin-
municated by worm and wheel to the main shaft of my improved machine, such
motion is transmitted to the train of wheels and consequently to the axis carrying the
upper series of bobbins. A suitable number of the hanks of yarn to be dyed is passed
over or under each bobbin or creel on one frame and then under or over each
corresponding bobbin or creel on the other frame, the said hanks occupying vertical
positions between the two frames, and being distended or drawn tightly against the
peripheries of the bobbins when the frames are furthest apart by means of springs
acting on the bearings of the bottom series of bobbins, this being done so that the
hanks will be caused to travel around with the bobbins for the purpose of presenting
each portion of the hanks to the free action of the dye liquor in the vessel or tank in
which my improved machine works.
When the machine is in operation the bottom frame is alternately raised and
lowered by the cam and arrangement of levers previously mentioned, the effect of
which is to alternately slacken and tighten the banks of yarn which when tightened
or distended, are carried around by the rotary motion given to the upper series of
bobbins and when slackened are caused to open out and allow the threads to separate
so that each portion of the yarn whether in the middle or on the outer sides of the
hanks is freely and equally exposed to the action of the dye liquor in the vessel, by
which means an equal and level colour, shade or tint is produced throughout the whole
of the yarn in the machine, and this is effected without the yarn becoming entangled
or folded as is the case at present.
Suitable guides and steadying rails or supports are provided for guiding and
steadying the bottom frame as it is raised and lowered.
When the lower frame is raised, the parts for giving rotary motion to the upper
series of bobbins are automatically thrown out of gear, and then again placed in gear
when the bottom frame is lowered.
The bottom frame is provided with cross bars or rods placed under the centre of
each bobbin so that when the hanks are slackened as above set forth, the springs
connected with the bearings of said bobbins draw such bobbins against the cross bars
so as to hold the banks thereon and keep the hanks on one bobbin separate from those
on the next bobbins.

Improvements in Hank-dyeing Machines.
I RICHARD GEE, of New Hay, Lindley, near Huddersfield, Yorkshire, Engineer
do hereby declare the nature of this invention and in what manner the same. is to
be perforined, to be particularly described and ascertained in and by the following
statement:
This invention refers to hank dyeing machines and consists in the method of and
means for subjecting hanks of yarn to the action of dye liquor for the purpose of
producing an even and level colour, shade, or tint upon the yarn, throughout its
entire length, so that one portion thereof shall not be lighter or darker than another
portion, or otherwise unequally dyed.
In order to carry out my invention I employ suitable framework for supporting
the bobbins or creels which are to hold the banks of yarn, one series of bobbins being
mounted in bearings on the upper frame and a corresponding series mounted in self-
adjustable bearings on the lower frame, the two said frames being connected together
by a suitable arrangement of levers or levers and links, which, when operated by an
eccentric or its equivalent, cause the lower frame to be raised or to advance towards
the upper frame, and this is done as the said eccentric revolves.
The axes carrying the bobbins or creels on the upper frame are connected or geared
together by a train of toothed wheels so that when rotary motion is communicated
by worm and wheel to the main shaft of my improved machine, such motion is
transmitted to the train of wheels and consequently to the axes carrying the upper
series of bobbins. A suitable number of the hanks of yarn to be dyed is passed over
or under each bobbin or creel on one frame and then under or over each corresponding
bobbin or creel on the other frame, the said banks occupying vertical positions between
the two frames, and being distended or drawn tightly against the peripheries of the
bobbins when the frames are further apart by means of springs acting on the bearings
of the bottom series of bobbins, this being done so that the hanks will be caused to
travel around with the bobbins for the purpose of presenting each portion of the
hanks to the free action of the dye liquor in the vessel or tank in which my improved
machine works.
When the machine is in operation the bottom frame is alternately raised and
lowered by the eccentric and arrangement of levers previously mentioned, the effect
of which is to alternately slacken and tighten the hanks of yarn, which, when tightened
or distended, are carried around by the rotary motion given to the upper series of
bobbins, and when slackened are caused to open out and allow the threads to separate
so that each portion of the yarn whether in the middle or on the outer sides of the
hanks is freely and equally exposed to the action of the dye liquor in the vessel, by
which means an equal and level colour, shade, or tint, is produced throughout the
whole of the yarn in the machine, and this is effected without the yarn becoming
entangled or felted, as is the case at present.
Such being the nature and object of my said invention, 1 will now make reference
to the accompanying sheets of drawings illustrative thereof, wherein Fig. 1 is elevation
of a hank dyeing machine constructed according to my invention, and Fig. 3 section
thereof. A represents, in section, the dyeing cistern or vessel; B represents a
rectangular frame employed for the purpose of carrying detachable cross rails or bars C
on which the banks to be dyed are suspended. These cross rails or bars are made
to revolve intermittently, and they can be easily removed from their position, as one
end is inserted into a square or other angular hole formed in the boss of each of the
pinion wheels D, as shewn in Fig. 4, the opposite end of the said crossbars being
inserted in a hole in the opposite side of the rectangular frame, or the said bars may
be otherwise conveniently attached. In addition to the hanks passing over the cross-
bars C, the lower part of the hank passes underneath rollers E which will revolve
with the bank, and in order that the said banks may be at a suitable tension, these
bottom rollers are carried by pedestals F provided with projecting spindles or studs G

page_text: and nuts H, between which nuts, and the underside of the frame B', are spiral
springs I which will keep the lanks at a suitable degree of tension, as will be well
understood. As already stated, the spur wheels have an intermittent rotary motion
imparted to them, and this is effected by means of a spaced wheel J, receiving its
motion from worm and wheel K, driven by cone L, or other suitable method of
driving may be employed. During the time the pinions D are not revolving, I cause
the lower rectangular frame B' to be raised as shewn in Fig. 2 for the purpose of
slackening and loosening the yarn, allowing the dye liquor to more freely permeate or
saturate the yarn. The means I employ for raising the lower frame during the time
the pinion wheels D are dwelling is effected by the arrangement of levers, rods, and
links M, N, and O, operated by the eccentric P and rod Q driven by the worm and
wheel already referred to. As soon as the bottom rectangular frame has been lowered
back into its position as shown in Fig. 1, the space wheel J is so timed as to
commence revolving the pinion wheels, whereby the banks are again made to travel
in the dye liquor.
Although I have shewn that the rectangular frame carrying the banks may be made
to approach for slackoning the yarn by means of the bars and rods M, N, and O, such
frames may be brought nearer together by racks and pinions or other like means.
It will be understood that instead of the hanks being driven intermittently, they
may be driven continuously by removing the space wheel and using a wheel full of
teeth. Provision is made for raising the rectangular frames out of the machine when
changing the hanks, or for removing the frames to other machines for washing and
chroming purposes, and this is done by sliding the framework upon vertical pillars R
by means of racks and pinions or chains and weights passing over pulleys, or other
convenient means may be employed for raising the frames out of the dyeing vessel
but which forms no part of my invention.
;
Instead of driving the hanks intermittently by means of a space wheel Jas
already described, such hanks may be driven intermittently by other mechanical
contrivances.
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 :-
Firstly. In bank dyeing machinery, the use of rectangular frames for carrying
cross rails or hobbins having intermittent rotary motion imparted to them, as described
and illustrated and for purposes set forth.
Secondly. In machinery for dyeing hanks of yarn, the use of rectangular frames,
one of which is made to approach the other for the purpose of slackening the yarn as
described and illustrated.
Thirdly. In machinery for dyeing hanks of yaru, the use of intermittent or con-
tinuously revolving crossbars for supporting hanks in combination with rectangular
frames, one of which is made to approach the other in manner and for purposes
substantially as described.
