page_text: I, THOMAS WOLSTENHOLME, of 730, Walnut Street, Camden, in the County of
Camden, and State of New Jersey, United States of America, Yarn Dyer,
do hereby declare the nature of this invention awl in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention consists in a machine for dyeing yarns, by means of which the
yarns may be thoroughly dyed without breaking or matting the same.
The Invention will be described with reference to the accompanying drawings
forming part of this specification, in which figure 1 is a side elevation of the
improvement, showing the tank in section; Figure 2 is a vertical cross-section of the
and
same; Figure 3 is an enlargod end elevation of part of the yarn-stick frame;
figure 4 is an enlarged end elevation of part of the beam for raising and lowering
the yarn-stick frame.
Similar letters of reference indicate corresponding parts in all the figures.
A is the tank, of suitable size and construction, containing the dye-stuffs and
supporting on its outside at one side a main driving shaft B having a rotary motion
derived from a suitable machine. At each end of the shaft B there is a crank arm 0
pivotally connected by the connecting rods D with the beams E mounted to swing
on top of the tank A at each end. The inner ends of the beams E support the
yarn-stick frame F in the tank A in such a manner that the said frame F can be
easily attached to, or detached from, the beams E. For this purpose, I have fastened
to the ends of the frame F the trunnions F1 fitting into bearings on the inner ends
of the beams E, the said bearings being each provided with the hinged
part E' held in place on the other part by a spring E, as plainly shewn in figure 4.
When the operator lifts the spring E the hinged part of the bearings swings
downward so that the respective trunnion F¹ becomes disengaged from the bearing
of the beam E. On the frame F are also formed the inwardly projecting pins F
on which can be hooked the ends of the chains G' connected with each other by the
rods G² G³ to form the support G held on a tackle H of any approved construction

page_text: and supported on a carriage H' mounted to travel on a beam H extending above the
tank A. When the chains G' are fastoned to the hooks and the trunnions F
are detached, as above described, from the beans E then the operator can raise or
lower the stick-frame Fout of, or into, the tank A. by the tackle LL. When the
stick-frame is out of the tank A it may be moved to any desired place along the
beam by the frame supporting the tackle UI and travelling on the said
beam H. The yarn stick frame is proforably rectangular in shape and supports
at its upper end the longitudinal benins 11' placed opposite each other and supporting
the yarn sticks J which rest in suitable notches in the top of the beams I L
In the lower part of the yarn-stick frame F are held to slide vertically the
beams supporting the yarn-sticks L in suitable notches L in the sliding
beams. The yarn to be dyed is placed on two corresponding sticks J and L, and
the said sticks with the yarn are placed on the beams 1 and so that tho yarn is
held in a vertical position, as plainly shown in figure 1. The beams are held
adjustably on the frame by means of pins N passing through the heads of the
beams and received in holes in the side beams of the frame F, as seen in
figure a latch O, pivoted to each head of the beams, serves to lock the
pins N in place. The beams are male vertically adjustable so as to necom-
nodate yarns of different lengths. In order to hold the yarn sticks J and Lin
place on their respective beams I l' and kk', I place a strip across the top of the
ends of the sticks and fasten the said strips under keepers Q having at their upper
onds an angle or projection and being secured to the beams I land respectively.
At the outer end of each beam E is placed a counterweight R, to counterbalance the
weight of the yarn stick frame F and its contents.
The operation is as follows:-The yarn stick framo F when out of the tank A is
filled with the strands of yarn supported on the yarn sticks J and L, as above
described. The tank A is filled with the desired dye stuffs and then the frame Fis
moved over the tank by the tackle H, above described, and let down into the tank
to the desired depth. The trunnions F are then connected with the inner ends of
the beams E, in the manner above described, after which the chains G are unhooked
from the hooks F. The main driving shaft is now sat in motion so that an up and
down swinging motion is imparted to the beams E which latter impart a like motion
to the frame F whereby the yarns are moved up and down in the dye stuff in the
tank A. This operation is continued for the necessary length of time after which
the motion of the alaft B is interrupted, the chains G are again hooked on to the
hooks and the trunnions F¹ are disengaged from the beams E. The tackle H
is then sot in motion so as to raise the frame out of the tank A and the frame
is transported to any desired place, by the means above described. It will be soen
that the frame F, when moved up and down in the dye stuff, causes the latter to
come in contact with all parts of the yarns so that the lattor are thoroughly dyed ;
at the same time the yarns are hold in an oven position, preventing breaking and
matting of the strands as the latter are hold on the locked sticks J and L. Tho
yarn, boing held a littlo slack on the yarn sticks J L, permits it to lift from the
top sticks during the downward movemont of the frame F and to fall from the bottom
sticks during the upward motion of the frame F, thus admitting the dye between tho
yarn and sticks.
Having now particularly described and ascertained the nature of the said invon-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
:-
1. The combination, with the tank and the yarn stick supporting frame having
opposite trunnions I, of the vertically rocking lovers E pivoted between their ends
at opposite sides of the tank and having two part bearings receiving tho said
trunnions and provided with latches E³, the main shaft connecting rods D operated
by the said shaft and connected at their upper ends to the outer ends of the levers B,
and hoisting mechanism for raising the frame out of the tank when the said boarings
are unlatched, substantially as set forth.

page_text: 2. The combination, with stick-supporting frame F having the vertical bars
provided with holes F and the upper stick-supporting beams II, of the vertically
adjustable beans having heads F sliding upon the said vertical bars, pins Ň
passing through said heads into the said holes, and latches O holding the pins in
place, substantially as set forth.
3. In a dyeing machine, the combination, with a tank containing the dye stuffs, of
a frame adapted to pass into the said tank and supporting the yarns, a tackle
supporting the said frame, and a carriage supporting the said tackle and mounted
to travel horizontally, substantially as shown and described.
4. The combination, with the rectangular frame F having upper and lower stick
supporting beams II' k¹ and the angular keepers Q the horizontal arms of which
project upwardly across the upper faces of said beams, the sticks resting at their ends
on said upper faces, and the strips P placed between the said horizontal arms of the
keepers and the ends of the sticks, substantially as set forth.
