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
"and in what
of my invention for "IMPROVEMENTS IN YARN DYEING MACHINES
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
This invention relates to machines for dyeing yarn in skeins.
The object of this invention is to provide a machine which shall have the capacity
of carrying a large quantity of yarn in the process of dyeing, and occupy a minimum
space.
And to that end the invention consists mainly of a machine comprising a dye-
liquor vat, vertical rotary disks above said vat, endless bands or chains extending
around the top portion of said disks, and suspended therefrom and passing through the
interior of the vat, and yarn supporting bars carried on said bands or chains at the
inner and outer sides of the latter, all as hereinafter more fully described and
specifically set forth in the claims.
In the annexed drawing, Figure 1 is a front elevation of a yarn dyeing machine
embodying my improvements Figure 2 is a vertical transverse section on line x, a,
Figure 1, Figure 3 is an enlarged detached plan view of one of the yarn supporting
frames, and Figure 4 is an end view of the same.
Sinilar letters of reference indicate corresponding parts.
A represents the vat containing the dye-liquor, B and B' denote two pairs of disks
secured to the ends of the shafts a a which are disposed axially horizontal and parallel
one above the other. The lower disks B' being arranged in the vat A and having
their shaft a journaled in suitable boxes or bearings in opposite sides of the vat,
and the upper disks having their shaft journaled in bearings secured to posts P P
rising from the aforesaid sides of the vat. To one of said shafts is attached a driving
pulley C and, if desired to relieve the chains or bands hereinafter described from the
strain of transmitting motion from one of the aforesaid pairs of disks to the other,
gears c, c, may be attached to the shafts of the disks and an intermediate
pivoted to the post P to transmit motion from the gear c to the gear c¹, and thus
rotate the two pairs of disks, in one and the same direction.
gear
Around the two pairs of disks B, B' are extended two endless bands or chains a¹, a¹
to each of which are firmly secured a series of frames b b b preferably' at the centres
of the lengths of the latter, and at right angles to the central portions of the links
means of
of the chain. Said frames being sustained at such angles by
braces extending from the ends of the frames obliquely to the ends of the
links and firmly attached thereto. On the inner and outer ends of the frames b'b
are mounted the yarn supported bars d d which are detachably connected thereto in
any suitable manner which may consist in providing the frame with notches or
recesses e e for the reception of the ends of the bars d d and placing across the said
notches or recesses straps pivoted at one end and held at the opposite end by
removable pins or screws.
I preferably attach to one or both ends of one of the bars d of each set or pair,
pins projecting radially therefrom, and to the post or posts P P, I attach a detent h
with which the said pins come successively into contact during the travel of the bands
or chains a¹ a¹ and by said contact the yarn supporting bars d d receive an intermittent
rotation and thus shift the skeins of yarn longitudinally. Said shifting being desired
in order to dye the yarn more evenly.
I do not limit myself to the employment of both pairs of disks B B¹ inasmuch as
the lower disks B₁ may be dispensed with and the chains may be made sufficiently

from kinking, and in this case the driving pulley or gear will be attached to the shaft
of the upper disks.
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
First. A yarn dyeing machine comprising a dye-liquor vat, a pair of rotary disks
above said vat, endless bands or chains extending around the top portion of said disks
and suspended therefrom and passing through the interior of the vat and yarn sup-
porting bars carried on said bands or chains to the inner and outer sides of the latter,
as set forth.
Second. A yarn dyeing machine composed of a dye-liquor vat, a pair of rotary disks
secured to the ends of a shaft arranged axially horizontally in the vat, a pair of rotary
disks secured to the ends of a shaft arranged above the vat and axially parallel with
the lower shaft, endless bands or chains extending around the two pairs of disks, and
yarn supporting bars carried on said bands or chains at the inner and outer sides of
the latter, as set forth.
Third. A yarn dyeing machine consisting of a dye-liquor vat, two pairs of rotary
disks secured to the ends of shafts arranged axially parallel one above the other, and
the lower of said disks dipping in the vat, endless bands or chains extending around
the two pairs of disks, frames secured at the centre of their lengths and at right angles
to said bands or chains, and yarn supporting bars connected to the inner and outer
ends of the frames and parallel with the aforesaid shafts, substantially as described.
Fourth. In combination with the dye-liquor vat A, two pairs of disks B B¹ and
chains a', a' the frames bb secured central of their lengths to the centres of the chain-
links, the braces 6' 6' extending from the ends of the frames to the ends of the links,
and the yarn supporting bars d d carried on said frames, substantially as described
and shown.
Fifth. In combination with the vat A and two pairs of disks B B¹ the endless
chains a¹ a¹ frames 6b attached to said chains, the rotary yarn supporting bars d d
carried on said frames, pins projecting from the said bars, and a detent in the path of
the pins, substantially as described and shown.
