Improvements in Machines for Dyeing Cotton and Analogous
Materials.
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 for "IMPROVEMENTS IN MACHINES FOR DYEING COTTON AND
ANALOGOUS MATERIALS," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The purpose of this invention is to thoroughly and evenly dye raw cotton stock in
an economical and expeditious manner.
And it consists in the combination, with the rotary dipping cylinder or cage, of
bars extended through the interior of the said cylinder or cage in such positions
as to cause the cotton to fall upon said bars and thereby break up and distribute
the partially wetted clods during the rotation of the dipping cylinder or cage, all
as hereinafter more fully described and specifically set forth in the claims.
In the annexed Drawing, Fig. 1 is a front elevation of a dyeing machine
embodying my invention, Fig. 2 is a vertical transverse section on line x, x, Fig. 1,
Fig. 3 is a vertical longitudinal section on line y, y, Fig. 2, Fig. 4 is a vertical
transverse section on line z, z, Fig. 1, and Fig 5 is a detached transverse section of a
modification of the breaker-bar
Similar letters of reference indicate corresponding parts.
A represents the vat in which to deposit the dye liquor, and "C" is the rotary
dipping drum or cage which is journaled in suitable bearings secured to the top
portions of the end walls of the vat and has attached to its shaft at the outside of the
vat a pulley-P-by which to transmit rotary motion to said drum.
The peripheral wall of the drum is perforated and the interior of the drum is
divided into separate and distinct longitudinal compartments by perforated longitu-
dinal partitions-a-a-a-which are extended tangentially from a cylinder-c-
arranged in the drum concentric with the axis thereof and rigidly secured thereto.
Said partitions forming acute angled pockets-6-6-in the portions of the
compartments adjacent to the periphery of the drum for the purpose hereinafter
explained. Each of the compartments of the drum is provided with a door-d-
in the periphery of the drum for introducing and removing the cotton.
a bar-e-which is
Longitudinally through each compartment is extended
arranged at or near the center of the compartment or in other suitable position
to effect the purpose hereinafter explained.
Said bars which I designated breaker-bars, may be of any suitable shape in cross-
section and may also be armed with laterally projecting pins or wings as represented
in Fig. 5 of the Drawing, and I prefer to pivot them to the heads of the drum-C-
and extend one of the journals of each through one of the heads of the drum and at
the outside of the latter I rigidly attach to said journals either friction rollers or
pinions---which traverse a segmental track or rack-n-which is arranged
above the vat concentric with the axis of the drum and firmly secured to a
breast D which rises from the top of the vat.
The operation of my improved Dyeing machine is as follows:
The dye liquor being deposited in the vat-A-and the cotton introduced into
the compartments of the drum-D-and the doors-d-d-d-thereof closed, the
drum is set in motion which is in the direction indicated by arrows in Fig. 2 of the
Drawing.
During the motion of the drum the cotton in the compartment which rises from the
vat falls into the acute angled pocket of said compartment adjacent to the periphery
of the drum, owing to the tangential disposition of the partition-a-and hence the
cotton is carried the maximum distance through the dye liquor.

page_text: In passing over the top of the vat the rollers or pinions---of the
bars in the elevated compartments transverse the track-n-and thereby
cause the said bars to revolve. The cotton falling out of the acute angled corners or
pockets-b-b-of the compartments strikes the rotating bars-e-e-which break
up the lumps of cotton and distribute the cotton in its descent and thus allows the
dye liquor to thoroughly permeate the cotton and uniformly dye the same.
I do not limit myself to the use of a single bar―-in each compartment of the
drum-C-as it is obvious that two or more such bars may be arranged in each
compartment.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1-In combination with the vat-A, the rotary drum-C-divided into separate
and distinct compartments and perforated to admit the dye liquor, and breaker-
barsee extending through the central portions of the compartments as and
for the purpose set forth.
2-In combination with the vat-A,-the rotary drum-C-formed with the
central cylinder-c-and tangential partitions- -a-a-extending from said
cylinder to the periphery of the drum, dividing the latter into a series of separate and
distinct compartments, and breaker-bars- -extending through the central
portions of the compartments, substantially as described and shown.
3-In combination with the vat-A,-the rotary drum-(-divided into separate
and distinct longitudinal compartments, the rotary breaker bars-e-e-extended
longitudinally through the central portions of said compartments and pivoted to the
heads of the drum and having their journals extending through one of said heads,
pinions on the protruding ends of said journals, the breast-D-rising from the
vat, and the segmental rack-n-attached to said breast substantially as described
and shown.
