Improvements in Dyeing Machines.
I, GEORGE MICHAEL UNDY, of 1133 Snyder Avenue, in the City of Phila-
delphia, Pennsylvania, United States of America, Salesman, do hereby declare
the nature of the said invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention relates to certain improvements in machines for dyeing hanks or
skeins of yarn, and it consists in the employment of a device for traversing the yarn
carrying bars from end to end of the vat or tank and an oscillated or continuously
revolved arm for returning the bars to the feed end of the tank or to deliver them
from such tank when necessary, as more fully described hereinafter.
In the accompanying drawings:-
Fig. 1, is an elevation of a yarn dyeing machine constructed in accordance with
my invention;
.
Fig. 2, is a transverse section of the same on the line 1-2, Fig. 1;
Fig. 3, is a perspective view of one of the lifting arms;
Fig. 4, is a side elevation of a modified form of machine;
Fig. 5, is a sectional view on the line 3-4, Fig. 4; and
Fig. 6, is a perspective view of one of the arms used in the modified construction
of machine illustrated in Figs. 4 and 5...
Referring to the drawings, A, represents a vat or tank provided at or near its
opposite.ends with transverse shafts a, b, on which are mounted sprocket wheels B,
carrying a chain. C, to which motion is imparted in any suitable manner, in the
direction of the arrows.
D, represents the yarn carrying bars which are placed between upright fingers c,
on the chain at the feed end of the machine and are traversed by said chain to the
opposite end of the tank, the bars resting on the edges of the tank but having their
ends projecting for some distance from its opposite sides.
.E, represents brackets bolted to the opposite sides of the vat at about its central
portion and on. stub shafts e, on said brackets are mounted pinions F, secured to or
forming part of lifting arms G. An oscillating movement is imparted to these
arms G, to move them from the position shown in full lines to that shown in dotted
lines, and back again, by any suitable mechanism, such for instance as a segment H,
meshing with the pinion F, the segment being pivoted to a standard at h, and
having an oscillating movement imparted to it by a rotating crank wheel I, through
the medium of a connecting rod i
"
At the outer end of each arm G, is a block J, pivoted at ; to the portion G, and
normally held in the position illustrated in Fig 3, by means of a spring k. The
block is slotted at 1, and the open mouth of the slot is covered by an inclined
block m, carried by a spring n, which normally tends to hold the inclined block in
the position illustrated.
At the front or feed end of the tank are wedge shaped blocks P, adapted to act
upon. the blocks J, when brought into contact therewith.
Q, are uprights secured to the machine at the feed end, and provided at their
upper ends with bearings for a shaft g, carrying sprocket wheels R, R, and to
which motion is imparted by a belt, extending to a pulley S, running loosely on
the shaft b, and adapted to be driven when required by being engaged by a clutch 8
of any suitable character.
These shafts q, form the fulcrum for bars T, the outer ends of which are provided
with bearings for a shaft t, on which are mounted sprocket wheels U, connected by
a chain. V, having fingers v,. with the sprocket wheels R, on. the shaft . This
frame and its chain are. normally in the position shown. in dotted lines in Fig. 1,
D

page_text: when the machine is in operation, being held up in such position by pawls w,.
adapted to steps W, on the upright Q, as shown in Fig. 2.
In operation, the bars containing the yarn are placed one by one upon the chains
which move said bars in the direction of the arrow towards the opposite end of the
tank. Just before reaching such opposite end, however, the arms G, are moved.
causing the inclined blocks m, on the blocks J, to come into contact with the upper
edge of the bar, forcing the springs n, outward and permitting the bar to enter the
recesses I; the springs n, then return the inclined blocks m, to their normal position
and the bar is held within the recesses.
•
The motion of the arms G, is then reversed and they are moved in the direction
of the arrow until the blocks J, come into contact with the inclined blocks P,
causing such blocks to be forced outward against the action of the springs k, and
effecting the release of the yarn carrying bar D. The movement of the chain is
so timed that as the bar is released, a pair of fingers c, will be brought immediately
beneath the bar to receive it and again traverse it towards the opposite end of the
tank; the arm G, then returns to carry the next bar back, and the operation is
continued as long as necessary, to effect the complete dyeing of the yarn. All parts
of the yarn are subject to the action of the dyeing fluid owing to the fact that the
bars are turned half way round, while being carried from one end of the machine
to the other by the arms G, but when it is desired to deliver the yarn from the
machine after the operation of dyeing has been completed, the bars T are brought
down to the position illustrated in full lines in Fig. 1, and the clutch thrown in so
as to rotate the chains V, in the direction of the arrow so that as the arms G,
arrive at a point midway of their throw, the blocks J, are operated upon by inclined
blocks y, projecting from the arms T, are opened and the bars are delivered at that
point, the fingers v, on the chain V, catching the bars and traversing them to the
end of the bars T, from whence they are forced unto bars Z, which are adapted
normally to slide on the bars T, but when the yarn is being delivered, are drawn
out to receive the same.
In the modification illustrated in Figs. 4, 5, and 6, the operation is the same
except that the arms G', are rotated continuously in one direction, and the blocks J',
are forced back at one end of the tank by an inclined block, to receive the ends of
the yarn carrying bars within an orifice I', the discharge being effected as before
at the opposite end, by an inclined block P', which forces back the blocks and
permits the delivery of the yarn carrying bar between the fingers c, on the
chain.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination in a yarn dyeing machine, of the tank, the yarn carrying
bars, chains for moving said bars from end to end of the tank, and arms pivoted on
the opposite sides of said tank adapted to carry the bars from one end of the tank
to the other, substantially as specified.
2. In a yarn dyeing machine, the combination of the tank, the yarn carrying
bars, devices for traversing the same along the edge of the tank, and pivoted arms
adapted to carry the yarn carrying bars from one end of the tank to the other, with
blocks at the outer ends of said arms, said blocks having pockets for the reception
of the ends of the yarn carrying bars, substantially as specified.
3. The combination in a yarn dyeing machine, of the tank, the yarn carrying
bars, devices for traversing the same along the edges of the tank, pivoted arms on
the opposite sides of the tank, blocks J, on the outer ends of said armis, pockets in
said blocks for the reception of the yarn carrying bars, and devices for operating
upon said blocks, substantially as specified.
4. The combination in a yarn dyeing machine, of the tank, the yarn carrying
bars, devices for traversing said bars from end to end of the tank, and pivoted arms
on the opposite sides of said tank adapted to carry the bars from one end of the

inclined blocks adapted to close the mouths of said pockets and springs adapted to
act upon said inclined blocks, substantially as specified.

adapted to operate upon the blocks J, and effect the release of the yarn carrying
bar, substantially as specified.
