Improvements in Dyeing Machines.
I GEORGE HERBERT CRAVEN of 2539 North 12th Street in the City of Philadelphia
State of Pennsylvania one of the United States of America Dyer 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 object of my invention is to so construct a machine for dyeing skeined yarn
that the yarn will be carried through the dyeing liquid up over the vat and into the
liquid again by continuously moving mechanism, and this object I attain in the
manner hereinafter described, reference being had to the accompanying drawings,
in which--
Figure 1, is a side view of my improved yarn dyeing machine ;
Figure 2, is a sectional plan view of one end of the machine;
Figure 3, is a transverse sectional view on the line 1-2, Figure 1;
Figure 4, is a longitudinal sectional view on the line 3-4, Figure 3; and
Figure 5, is a view of a detail of my invention.
A is the vat or tank containing the dyeing or other liquid, this tank in the present
instance being quadrangular in form and open at the top.
B is a frame mounted on the vat or tank and provided with bearings for four
transverse shafts D, D1, D2, and D³; D being the driving shaft, provided in the
present instance with a worm wheel d, meshing with a worm c on a short shaft C,
which has fast and loose pulleys for the reception of the belt by which the machine is
driven.
On each side of the vat A is a longitudinal belt E, which passes over a sprocket
pulley d on the shaft D and over a belt pulley d' on the shaft D', each belt E being
provided with a series of fingers e, e, preferably with bent ends, which engage with
the ends of the yarn carrying bars or sticks J, which slide upon rails a, a, on the
upper edge of the tank or vat A. Chain belts are shown in the present instance, but
any suitable belts may be used.
On the shaft D are sprocket-wheels f, around each of which passes a vertical
belt F, which extends up to and around a wheel f¹ on the shaft D³. These belts
also have fingers f³, on which are carried the yarn bars or sticks J, the belts being so
timed that the fingers on the belts F will remove the bars J from the fingers of the
belt E.
On the shaft D₁ are belt wheels g, g, around each of which passes a vertical belt G
which extends upward and over a belt wheel g¹ on the shaft D³. This belt has
fingers g, similar to the fingers on the belt E.
Extending from the shaft D' to the shaft D³ are two belts H, which pass over belt
pulleys hh on the shaft D2 and over sprocket pulleys h¹ on the shaft D³. These
belts H are provided with fingers 2, which traverse the yarn carrying bars from one
vertical belt to the other. The direction of the movement of the belts is indicated by
the arrows, Figure 1.
Hung by brackets i, i, on each side of the frame B are rails I, I, on which rest the
bars J in their travel across the machine from the vertical belts G to the belts F,

page_text: under control of the belts H. It will be noticed, on reference to the drawings, that
the inner run of each belt G in inclined, which tends to prevent the bars from
dropping off the belt when they are raised from the belt E to the belt H.
The machine is so timed that the fingers on the belts G will remove the bars J
from in front of the fingers on the belts E without stopping the machine, and the
fingers on the belts H will likewise remove the bars from the belts G and transfer
then onto the rails I without stoppage of the machine. The fingers on the belts H
push the bars J from off the rails I onto the fingers on the inner run of the vertical
belts F, which deposit the bars onto the rails a, a, allowing the yarn to be submerged
in the liquid in the tank or vat.
A flanged roller m is hung in the skeins of yarn, so as to keep them from tangling
and twisting in their passage through the liquid and over the tank.
In order to guide the rollers m and the yarn into the vat, I provide inclined guide
ways n, adjacent to the belts F, so that as the bar carrying the yarn and the roller is
let down into the liquid by the belt the flange of the roller will strike the inclined
guide ways n and be directed into the tank.
It will be seen that the yarn is not wholly submerged in the liquid, a portion of
the yarn being above the liquid, and in order to dye this portion the bars are given a
slight rotary motion as they pass through the liquid, thus subjecting the whole of
each hank or skein to treatment. On each edge of the tank is a short rack a',
which engages with pinions ; on the bars, and as the bars are carried over this
rack by the belts E they will be rotated and the yarn turned, as will be readily
seen on reference to Figures 1 and 2.
The details of construction of the frame of the machine may be varied without
departing from my invention.
In order to test the yarn at intervals, I provide means by which all the sticks
or bars J can be permitted to accumulate upon the rails I, I, clear of the tank,
so that the yarn can be inspected, and if further treatment is desired can be again
submerged in the liquid. For this purpose the shaft D is provided with a second
sprocket wheel d³, of less diameter than the wheel d', and on the shaft D³ is a
sprocket wheel f³ of greater diameter than the wheel (see Figure 5). These
wheels are connected by a belt F1, and the hubs of the wheels f¹, f³, are pro-
vided with clutch teeth, with which may engage the teeth on the clutch H¹, carrying
the wheel of the belt H, so that when it is wished to place all the sticks or
bars upon the rails I, I, the clutch is thrown in gear with the teeth of the wheel f³,
thus diminishing the speed of the belts H, allowing the sticks to accumulate on
the rails I, I, after which the machine is stopped.
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 :-
1st. The combination, in a yarn dyeing machine, of the vat, the loose yarn
carrying bars, with horizontal belts E and H and vertical belts G and F, having
fingers thereon, and mechanism for driving said belts, whereby the yarn is carried
longitudinally through the vat and raised clear of the same and transferred to
the opposite end of the vat, substantially as set forth.
2nd. The combination, in a yarn dyeing machine, of the vat, the frame carrying
the longitudinal rails I, loose yarn bars adapted to the rails, horizontal belts adapted
to traverse the yarn carried by the bars through the liquid vertical belts for raising
the bars to the rails I, horizontal belts for traversing the bars on the rails I, and
vertical belts for transferring the bars from the rails to the vat, substantially as set
forth.
3rd. The combination, in a yarn dyeing machine, of the vat, the frame with the
independent horizontal and vertical fingered propelling belts, mechanism for driving
said belts, with loose yarn carrying bars propelled by said belts in a manner sub-
stantially as specified.
4th. The combination, in a yarn dyeing machine, of the vat, yarn carrying bars,

page_text: a series of belts driven substantially as described, with guides n at the feed end of
the vat and adapted to direct the yarn into the vat as the carrying bars are lowered,
substantially as set forth.
5th. The combination, in a yarn dyeing machine, of the vat, the frame, rails
carried thereby, loose yarn carrying bars, with horizontally driven belts E and H
and vertically driven belts G and F, and mechanism, substantially as described, for
decreasing the speed of the belt H, by which the yarn bars are packed on the rails,
substantially as set forth.
