Improvements in Dyeing Machines.
I, LEONARD WELDON, of 155 Division Street Amsterdam, County of Mont-
gomery, State of Now York, United States of America, Manufacturer, 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:—
My invention relates to yarn dyeing or drying machines of the class provided
with a revoluble frame for supporting the skeins of yarn, and the object is to
provide more simple and efficient means for turning the cross-bars supporting the
skeins, and adjusting the bars to the length of the skeins.
My invention consists in the combination with the revoluble frame for supporting
the skeins of yarn, of a shaft for said frame, a gear wheel keyed to said shaft,
a gear wheel loose on said shaft and having a different number of teeth from the
other, a gear wheel meshing with the first two gear wheels, a cam carried by the
loose gear wheel, a pawl operated by the cam, and a ratchet wheel engaging
the pawl and secured to a revoluble cross-bar supporting the skeins.
My invention consists also in the combination with the frame provided with
pairs of cross-bars to support the skeius of yarn, one cross-bar of each pair adapted
to be moved toward and from the center of the frame and a screw at each
end of said frame and engaging the bar to move the same toward and from the
other bar.
And my invention consists also in certain other combinations of parts hereinafter
described aud specifically set forth in the claime
Referting to the drawing hereto annexed and forming a part of this Specification,
Figure 1 is a side elevation of a dyeing machine provided with my invention,
Figure 2 is an enlarged end view of a portion of the revoluble frame and the
gear wheel secured to the stationary frame, and
Figure 3 18 a plan view of the gear wheels showing the stationary frame in
section and with parts of the revoluble frame broken away.
Referring specifically to the drawing, A indicates the stationary frame of the
machine consisting preferably, as shown, of two upright posts and a cross-beam
extending between and connecting the posts together at the top. A' represents
the vat for containing the dye liquor, in section. B represents the revoluble frame
consisting of a shaft, b, extending horizontally and adapted to turn in bearings a, a,
on the sides of the posts, arms extending radially from the said shaft near each
end thereof and between the posts, and preferably formed by pieces crossing each
other at right angles giving four arms at each end of the shaft, as shown in the
drawing, and two cross-bars c, c' extending between each pair of arms a distance
apart to support the skeins of yarn C. The said cross-bars extend parallel to the
shaft, b, one of each pair being placed nearer the shaft than the other, depending
upon the length and of the skeins to be held thereon In order that the skeinS
may be dyed evenly the said cross-bars are made to revolve so that all parts of the
skeins will be exposed to the dye liquor alike. The means for effecting the
rotation of the cross-bars will now be described.
On one end of each of the inner cross-bars c, between the arms and the post of
the stationary frame, I secure a ratchet wheel d; ou the shaft, b, close to the post
is keyed a cog-wheel, e. By the side of this cog-wheel is another cog-wheel, e¹,
loose on the shaft and of the same or about the same size as the other, but

page_text: differing from the other in the number of teeth in its periphery, that is, the loose
cog-wheel bas a greater or less number of teeth. As the skeins are revolved very
slowly a difference of one or two teeth is generally sufficient. The loose cog wheel
is provided with a cam, f, on its side and extending beyond its periphery.
Extending upon each arm and engaging the ratchet wheel thereon is a lougi-
tudinally movable pawl g. These pawls are shown secured to the arms by straps
in which they slide. One end of each pawl engages its ratchet wheel and the
other extends into the path of the said cam and is operated by the cam and made
to turn the ratchet wheel one tooth at each contact. The pawls are operated in
succession and their ends which engage the camp are broader and curved somewhat,
so that they will slide easily over the cam.
Each pawl has a retracting spring g' connected to it and is provided with a
stop g to limit the movement of the pawl by the spring. The stop is shown as a
pin projecting from the pawl between the straps to make contact with the inner
strap. It will be obvious, however, that other suitable and well known means may
be employed for this
purpose.
The loose cog-wheel e cariying the cam fis rotated by means of a cog-wheel i
journaled in the post of the stationary frame and having a broad periphery
engaging both cog-wheels on the shaft . By this means the loose cog-wheel will
be turned slowly either in one direction or the other, depending upon whether the
number of its teeth is greater or less than the number of the teeth on the wheel
keyed to the shafts.
G is a pulley on the shaft for a belt. In order to vary the distance between
the pairs of cross-bars c, c', to accommodate various lengths of skeins, I make the
bars nearest the ends of the arms movable toward and from the inner bars and
this effect by extending the gudgeons D, upon which the bars turn, through
slots, F, in the arms. These gudgeons are provided on their projecting ends with
nuts or threaded perforations to receive threaded screws or bolts E, which are
swiveled in lugs, k, projecting from the arms, one at each end of each of the slots.
The said threaded bolts extend opposite and lengthwise of the slots and are turned
to move the gudgeons by small wheels, h, on their outer ends. Each of the arms
are provided with the described adjusting devices.
It will be obvious that iny invention may be applied to either dyeing or drying
machines, and I therefore do not limit myself to the use of the vat, as a vat
or covering for the revoluble frame may be dispensed with when used for drying
yaro.
Having now particularly descubed 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 18;-
