Improvements in Yarn Dyeing Machines.
I, LEONARD WELDON, of Amsterdam in the County of Montgomery, in the
State of New York, United States of America, Manufacturer, do hereby declare
the nature of my 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 consists in a novel organization of a machine which dips the
entire batch of yarn simultaneously into the dye-liquor and lifts the same in like
manner out of the dye-liquor and thus materially expedites the dyeing process,
and which machine has each of its yarn supporting bars arranged to rotate in
opposite directions from the adjacent yarn supporting bars and thereby effectually
guards against the liability of the yarn on one bar becoming entangled with the
yarn on the adjacent bars and consequently permits said bars to be placed nearer
to each other than in other machines of this class.
Said machine possessing various other advantages over prior machines of this
class and combining simplicity of construction with superior efficiency of operation.
The invention is fully illustrated in the annexed drawing in which
Fig. 1 is a side elevation of a yarn dyeing machine embodying my invention,
Fig. 2 is a top plan view of the same,
Fig. 3 is a vertical longitudinal section on line x, x, Fig. 2,
Fig. 4 is a vertical transverse section on line y, y, Fig. 3 minus some of the yarn
supporting bars to better illustrate the form of the journal bearings in one side of
the yarn carrying frame.
Fig. 5 is an enlarged top plan view of one of the end portions of one side of the
yarn carrying frame, and the mechanism connected thereto for turning the yarn-
supporting bars,
Fig. 6 is an enlarged vertical transverse section of the aforesaid portion of the
yarn carrying frame, and mechanism connected thereto,
Fig. 7 shows detail views of the bolt which journals the yarn-supporting bar to
the frame and connects to said bar the mechanism for turning it, and
Figs. 8 and 9 are enlarged side views of said mechanism.
Similar letters of reference indicate corresponding parts.
A represents the vat in which is deposited the dye-liquor for dyeing the yarn.
Said vat is preferably of rectangular form in its horizontal cross section. To this
vat are rigidly attached the parallel inclined ways D' D' which rise above the vat
as shown in Figs. 1 and 3 of the drawing and may be terminated with horizontal
ways D D at their bases. From the upper ends of the ways D' D' are extended
horizontal ways D₁ D" for the purpose hereinafter explained.
B represents a horizontal rectangular frame which is provided at the ends of its
sides with carrying wheels a a by which said frame is mounted on the aforesaid
ways. Said frame is caused to move up and down on the inclined ways D¹ D¹ and
consequently toward and from the vat A by means of a crank or wheel F provided
with a crank-pin, to which is connected the pitman G which has its opposite end
fork-shaped as shown at G so as to allow it to engage a cross-bar on the end of the
frame B and push said frame up on the inclined ways D¹ D'. The frame
descending by gravity during the reverse movement of the pitman maintains the
latter in connection with the aforesaid cross-bar.
The fork-shaped end of the pitman allows the frame B to be drawn out of
engagement with the pitman and up to the upper horizontal ways D" D" and
along on said ways when desired to remove the frame from over the vat.
For the purpose of thus drawing the frame B to the upper ways D"D" I secure

page_text: to the latter a windlass H which has its shaft extended across the said ways and
journaled in posts secured thereto, and to this shaft is attached one end of a chain
or cable H', the opposite end of which is connected to the frame B. This windlass
I also utilize to facilitate the upward movement of the frame during the operation
of the machine by attaching to said windlass a counter weight I.
b b b denote the bars upon which are hung the skeins of yarn to be dyed. These
bars are preferably rectangular or otherwise polygonal in cross section and
extended across the frame B and journaled and detachably connected thereto by
being seated at one end in notches n n in the top of the rear side rail of the frame B
as shown in Fig. 3 of the drawing. The opposite end is inserted in a cup e secured to
the end of a bolt which has a smooth portion by which it is journaled in the front
side-rail of the frame B as shown in Fig. 6 of the drawing, and is formed with
circumferentially enlarged steps f¹ and fil one of which is screw-threaded and the
other is smooth as illustrated in Fig. 7 of the drawing.
To the screw-threaded portion fi of each bolt is fastened a ratchet-wheel c, and
to the smooth portion f is pivoted a gravitating arm d to the free end of which is
connected a pawl d' which engages the ratchet-wheel.
For turning the bars 66 automatically so as to shift the yarn longitudinally
during the operation of the machine I employ a bar C extending lengthwise of the
frame B and carried thereby movably longitudinally and partly independently of
the frame, by means of hangers h h attached to the front side-rail of the frame and
having pivoted to them sheaves ¹¹ on which the bar C rides. Said bar is formed
with upward projecting V shaped cams C¹ which engage pins i i secured to the
arms dd.
r
To one of the lower horizontal ways D or base of the inclined ways D' at one
end of the vat A is attached a stop E, and a similar stop E' is secured to the upper
part of the inclined way D' at the opposite end of the vat and same side of the
apparatus. Said stops are in the path or the bar C so as to cause one end of said
bar to encounter the upper stop E when the frame B.is pushed up on the inclined
ways D'D' by the pitman G. Said frame travels a sufficient distance after the
encounter of the bar C with the stop E' to cause the said bar to be pushed back on
the frame and by the engagement of the cams C¹ C¹ C¹ with the pins iii actuate
the arms d d d so as to turn the ratchet-wheels ccc by the pawls d¹ d' d'.
The bars bbb being compelled to turn with the ratchet-wheels causes the skeins
of yarn hung on said bars to shift longitudinally thereon. Said movement of the
yarn being insured by the weight of the yarn which at that time is lifted out of the
vat and saturated with the dye-liquor and thus has a firm hold on the polygonal
bar b.
A dog d¹ is pivoted to the frame B and engages the ratchet-wheel c so as to
prevent its reverse movement while the frame B descends on the inclined
ways D' D' and dips the yarn into the dye-liquor in the vat A. In the latter part
of this descending movement of the frame B the end of the bar C collides with the
lower stop E and is thereby pushed toward the opposite end of the frame sufficient
to bring the bases of the cams C¹ C' under the pins i i, and thus the arms are
allowed to drop by gravity, and the pawls d' d' obtain a hold on another portion of
the ratchet wheels, while the latter are held stationary by the dogs d¹¹ d
Inasmuch as the bar C has a vertical movement while in engagement. with the
aforesaid stops I guard against undue friction between said parts by pivoting
rollers 9 9 to the ends of said bar.
To guard against the entanglement of the yarn on one bar b with that hung
on the adjacent bar or bars, and to also allow the said bars to be arranged
closer to each other and thus increase the capacity of the machine,- I make each
bar rotate in opposite direction from the adjacent bar or bars, by pitching the
teeth of each ratchet-wheel in opposite direction from those of the adjacent
wheel, or wheels, and arrange the carms d d and pawls. d' d' accordingly as
illustrated in Figs. 8 and 9.of the drawing.
To allow the frame B to be drawn up on to the upper horizontal. way D" when
