.Improvements in or appertaining to Dyeing Machines.
We, MILFORD COCKROFT of No. 7 'Oban Street, Newfound-pool, Foreman,
and SAMUEL JOHN PEGG of No. 275 Humberstone Road, Engineer, both. of
Leicester in-the County of. Leicester do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in or, appertaining to dyeing machines
which has for its object-the facilitating of dyeing, removal and transference of rods
carrying the banks, doles or skeins, or tacked lengths of hose or socks, and in the
construction of the said rods, also the construction of the rod carrying and
traverse mechanism in connection therewith, and in arrangements for conveying
such rods after dyeing to a "washing off" machine.
To carry out our invention we employ in the first place, an arrangement of rod
carrying blocks in conjunction with rod grips or jaws, and links which when bolted
together.formansendless chain; or chains for carrying the rods.Sirehrarrangement
of appliances being fixed inside the dye tub, vat or tank so that when the outer
extremity of each circle of motion is reached the said grips or jaws will auto-
matically open to allow of the trol's 'being removed therefrom by hand, or be
transferred to a "washing off" machine. Or be replaced therein; and that will
close again upon the rods in returning to the horizontal traverse in either direction,
whether in the upper or lower line of traverse. Sath grips or jaws have hooked
ends theirdower parts, being rounded off so that when-two of the hooked ends come
together;-or-nearly. so, they enclose the trods, arranged in the rod carrying blboks,
by this means when the rods are in-the-lower-line of straverso they are securely
held, such grips or jaws are pivoted at their lower curved sends to tthe ends of the
rod carrying blocks and to links or plates on the opposite side; that when all are
bolted together they form an endless chain; grooves in the ends of the cod
carrying blockscallow of the teeth of the chain wheels to spropelathe chains in the
direction required. The driving chain wheels are mounted on a shaft carried in
rigid bearings fitted inside one end of the dye tub, xat or stank, or partly-insand
partly out of the said tub, vat or tank. The opposite chainwheels rare-mounted
on a shaftafittelin bearings which are vertically adjustable so as to allow for the
varying lengths of hanks of yarn. Both endless chains are fitted so that their
inner faces are close to the insides of the tub, vat or tapkato save room. Motion is
imparted to the endless chains and rod carrying and gripping devices by.a-chain
and worm shaft, or other well known means,vaud such motion may be reversed by
an arrangement of gears cross belts, or other well known mechanicaharrangements.
The rodsearoying blocks, forming part of the endless chains are cast or otherwise
made having an aperture or groove in one side thereof thhold the ends of the rods
carrying the banks or goods; a lip-being provided on the inside of each to act as
a.stay for the rods..
The rods carrying the yarn are perforated at intervals or made hollow, and they
may have solid-ends in which are secured theraxial pins and a series of small tubes
or rods of brass, wood or other suitable material, set either in a triangular or other
form and having at intervals collars, flanges, or discs soldered or brazed-thereto to
keep the shanks, doles or skeins in their respective positions. Or other similar
means may be employed for forming a hollow rod, so that in the upper traverse,

page_text: when the banks, doles or skeins are partly out of the dyeing liquid, the dye will
impregnate or drain through the yarn or goods.
When the hanks, skeins, or doles, or goods are in the lower line of traverse they
are entirely submerged in the dyeing liquid and not being impeded by weights,
open out and there is no danger of one hank getting entangled with another. The
great advantage obtained being a great saving in steam and dye-stuff, with double
the quantity of material operated upon and the employment of one man instead of
two as is now the case. In dyeing hose or soeks tacked together in lengths the
rods may be solid and have pegs inserted therein at intervals to seperate such
lengths.
If a machine is required for "washing off" to act with the dyeing machine
"pickers or claws" are arranged on or in the endless chains of the "washing off"
machine, which will, when the rods have reached the outermost end of the circle,
and the grips or jaws open, take them off and transfer them to the "washing off"
machine, by similar mechanism, and construction of chains as herein before
described.

Improvements in or appertaining to Dyeing Machines.
We, MILFORD COCKROFT of No. 7, Oban Street, Newfound-pool, Foreman,
and SAMUEL JOHN PEGG of No. 275 Humberstone Road, Engineer, both of
Leicester in the County of Leicester 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 :-
This invention relates to improvements in or appertaining to dyeing machines
which has for its object the facilitating of dyeing removal and transference of rods
carrying the banks, doles or skeins, or tacked lengths of hose or socks, and in the
construction of the rod carrying devices.
That our invention may be well understood we have appended a sheet of
drawings in which
Figure 1 represents one of the sides of a dye tub or vat fitted with the devices
according to our invention.
Figure 2 shows part of an endless chain drawn to an enlarged size, and in
accordance with our invention.
Figure 3. a view of the plate F and the joint pin holes f¹, therein, as seen in
Figure 2.
Figure 4. the links forming the chain shown in Figure 1.
Figure 5. an upper view of same.
Figure 6. an end left hand view showing the position of the plates F with the
rod carrying devices.
Figure 7 shows a portion of one end of a dye tub or vat D carrying the right
angled frame, bearings h, h', chain wheels G, G' tongues e frame rods, and post, and
. Figure 8 are cut off views of the various rods E employed, square, triangular,
fluted, and circular the latter having pegs e, therein for the purpose hereinafter
described.
Similar letters of reference represent like parts in all figures where they
occur.
To carry out our invention we employ in the first place an arrangement of rod
carrying blocks A, A¹ the former in conjunction with rod grips or jaws B, B¹ and
links C, which when bolted together form an endless chain, or chains running

page_text: parallel to each other for carrying the rods E. Such contrivances being fixed
inside the frame of the dye tub, vat or tank D. When the outer extremity of each
circle of motion or end of higher traverse is reached the said grips or jaws B, B
will automatically open to allow of the rods E being removed therefrom and
carried to a "washing off" machine. Or to replace fresh ones therein, said grips
or rods closing again on the rods in attaining the horizontal position, or traverse in
either direction by their hooked.ends 6 coming together or nearly so and enclosing
the rods arranged in the rod currying blocks A, such grips or jaws being pivoted
at their lower curved ends to said rod carrying blocks, links C, and plates F, FI
coming opposite each other, the latter seen in Figures 4, 5 and 6 act as stops for
the ends of the rods on one side of the machine only, such lip afterwards referred
to as ' fitting the opposite side of the dye tub to that shown in Figure 1. The
same being represented by A Figure 2. When all are bolted together the endless
chain, or chains Figures 1 and 2 are formed, spaces at the ends of the rod carrying
blocks allow of the teeth g, of the chain-wheels G, G' to propel the chains in the
direction required. The driving chain wheels G are mounted on.a shaft carried
in rigid bearings h fitted near one end of the dye tub, vat or tank, said wheels
being partly in and partly out of the said tub, vat or tank, "Figure 1." The
opposite chain wheels G' are mounted on a shaft fitted in bearings h', which are
adjustable in slot h³, so as to allow of the tightening up or slackening of the chains.
Both said chains are fitted so that their inner faces, or curved edge of plates F are
close to the insides of the tub, vat or tank to save room, such curved plates keeping
the
yarn from interfering with the mechanical parts of the machine.
Motion is imparted to the endless chains and-rod-carrying devices by a belt being
passed from driving shaft over the pulleys H on short worm shaft I working gear
wheel J, mounted on shaft h. Or by other well known means, such motion may
be reversed by an arrangement of gears, cross belts, or other well known mechanical
arrangements.
The rod carrying blocks A, forming part of the endless chain shown in Figure 2
are cast or otherwise made having an aperture or groove in one side thereof to
hold or admit the ends of rods E carrying the banks or goods. A lip is also
formed see A Figure 2 and F1, Figures 4, 5 and 6. to act as a stop or stay for
the rods.
Said rods E may be either square, triangular, fluted or round as seen in Figure 8
and kept in place on one side of the machine by tougues e, this is only necessary on
the side where the lips are not employed.
It will be observed that said contrivances are arranged to be lifted out of the
tub, vat or tank intact, in the following manner, but other means, such as chains or
pulleys may be adopted if desired, but we prefer that the iron frame K, bolted
together by tie rods K' shall be made at right angles "see Figure 7" to lie upon the
side frames of the dye tub, vat or tank, provided with side posts L carrying a
shaft M, upon which are chain wheels or pulleys N operated by gear wheel O and
worm P, the whole being lowered again at will by aid of the chains Q and balance
weights R on either side of the frame. The side posts L are bolted or otherwise
secured at intervals to the dye tub, vat or tank for the purpose above referred to.
When the yarn or goods are in the upper line of traverse the dye stuff will
impregnate or drain therethrough .and when in the lower line of traverse the yarn
or goods are entirely submerged in the dyeing liquid, and not being impeded by
weights the yarn will open out as d Figure 1 so that there is no danger of one
hank getting entangled with the other, or with one another. The great advantage
obtained being a great saving in steam and dye-stuff, with double the quantity of
material operated upon, and the employment of less manual labour.
In dyeing bose or socks tacked together in suitable lengths the rods may have
pegs e inserted at intervals to seperate such lengths, "see Figure 8."
To transfer the appliance intact to another vat or "washing off" machine it is
raised by the means hereinbefore described, and the rods removed therefrom in the
manner set forth.
