IMPROVEMENTS IN DYEING APPARATUS
Year: 1886

page_text: I, LEONARD WELDON of Amsterdam, County of Montgomery State of New York,
and United States of America, Manufacturer, do hereby declare the nature of my
invention for "IMPROVEMENTS IN DYEING APPARATUS" 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 the class of dyeing apparatus designed for dyeing textile
fabrics, and in which a rotary wheel or cylinder is arranged in the dye vat to
intermittently dip the articles to be dyed into the dye liquor.
And the invention consists in an improved construction and combination of the
component parts of the dyeing apparatus as hereinafter fully described and specifically
set forth in the claims whereby the efficiency of the dyeing apparatus is materially
improved.
In the annexed drawing Fig. 1, is an end elevation of my improved dyeing
apparatus, Fig. 2 is a front elevation of the same; Fig. 3 is a transverse section,
and Fig. 4 is a longitudinal section on line ær, Fig. 3.
Similar letters of reference indicate corresponding parts.
A-represents the dye vat which is of rectangular or other suitable shape, and water
tight, and-C-denotes the wheel or cylinder for dipping the articles to be dyed in the
dye liquor contained in the aforesaid vat. Said cylinder being journaled at opposite
ends in suitable boxes or bearings secured to the top of each end of the vat, and to
one end of the shaft of the cylinder at the exterior of the vat is secured a worm gear
wheel,-B-which meshes in a worm-D-journaled on the exterior of the vat, and a
pulley-P-fastened to the shaft of the worm-D and connected by a driving belt
with a suitable motor serves to transmit rotary motion to the cylinder-C.
I do not, however, limit myself to the aforesaid means for transmitting motion to
the cylinder as it is obvious that the same can be effected by other well known
devices.
In order to dispense with unnecessary room for dye liquor in the vat and to
economize in the use of said liquor, I form the exterior of the vat-A-with a
segmental solid bottom-F-extending from the top of one side of the vat to the
center of the bottom proper thereof, and with a segmental perforated false

page_text: .
bottom F extending from the top of the opposite side of the vat to the center of
the bottom proper of the same, the portion-H-of the vat immediately back of said
perforated bottom-F-constitutes a receptacle for the dye liquor; which is introduced
through the top of the vat and passes through the perforated bottom-F-into the
receptacle-H.
A gate-I-of any suitable and well known form is connected with the
receptacle H-to draw off the dye liquor when desired.
A represents a steam pipe which is extended into the receptacle-H--to heat
the dye liquor to the requisite temperature. The cylinder-C-I form of two stout
heads preferably each composed of two thicknesses or layers of wood with
the grain of one layer running cross-wise the grain of the other layer, so as to prevent
the warping of the head, said heads being secured to a wooden roller-c-through
which the shaft-d-of the cylinder is extended and to which it is fastened. Length-
wise the interior of the cylinder-C-are extended a series of buckets-IL-which
are secured at their ends to the inner sides of the heads---b. These buckets are
formed either V-shaped or similar angular shape in cross section and are arranged
adjacent to the periphery of the cylinder and preferably in such positions as to make
one side of each bucket form a longitudinal section of the exterior of the cylinder,
said side of the bucket being solid, while the other side-e-of the bucket is perforated
or composed of slats placed short distances apart; from the inner edge of each
bucket L-toward the center of the cylinder is extended a slatted or perforated
partition and near the aforesaid edge of each bucket is hinged at one edge
a gate which has its free edge extended toward the back of the adjacent bucket.
In the operation of the described dyeing apparatus the fabric or articles to be dyed
are thrown into the buckets-L-L-from the top of one side of the vat, and by the
rotation of the cylinder-C-said articles are carried in the buckets through the dye
liquor in the vat and are thus intermittently dipped or immersed therein.
The angular or-V-shape of the buckets causes the articles to be retained in the
buckets after leaving the bath of dye liquor without moving from the positions in
which they were taken up until the buckets are elevated to a position past a vertical
line over the axis of the cylinder-C-when the aforesaid articles fall by gravity out
of the elevated bucket and onto the back of the perforated side of the subjacent
bucket and partition--and during this fall the articles to be dyed are turned over
so that in their succeeding passage through the dye liquor and toward the top of the
eylinder, the dye liquor penetrates the layers of fabric in the buckets in opposite
direction from which it passed through the same during the previous revolution of
the cylinder and thus the fabric is dyed more uniformly throughout. Heretofore the
buckets of the wheel or cylinder-C-have been formed concave
transversely; and this form of the buckets caused the articles in process of dyeing
to be rolled over in the bucket and thus become more or less entangled or knotted
in a mess and dyed unevenly. This, it will be observed, is effectually obviated by
the angular or -V-shape of the buckets-I-L-of my improved apparatus.
or rounded
The delivery of the dyed articles from the dyeing apparatus, I make automatic by
turning the hinged or pivoted gates---so as to stand with their free edge toward
the hip or ridge of the back of the adjacent bucket as represented by the dotted lines
in Fig.
of the drawing. Said gates then serving as chutes upon which the dyed
articles drop from the elevated buckets and then slide out over the side of the vat.
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 a dyeing apparatus the combination with the rotary wheel or cylinder, of
buckets formed angular in cross-section as and for the purpose specified.
2-In a dyeing apparatus the combination with the rotary wheel or cylinder, of
buckets in said cylinder adjacent to the periphery thereof and of angular form in cross
section substantially as shown and set forth.
In a dyeing apparatus the combination with the rotary wheel or cylinder, of
buckets of angular form in cross section and adjacent to the periphery thereof, and

page_text: perforated partitions extending from the inner edge of the buckets toward the center
of the wheel or cylinder substantially as described and shown.
4-In a dyeing apparatus the combination with the rotary cylinder, of buckets
of V-shape in cross section and having one side solid and the other side perforated
and the solid side thereof constituting a longitudinal section of the exterior of the
cylinder substantially as described and shown.
5-In combination with the dye vat and rotary cylinder, buckets in said cylinder
and gates extended from the inner portion of the buckets toward the backs of the
subjacent buckets and adapted to be set inclining toward the exterior of the cylinder
substantially as and for the purpose set forth.
6 In combination with the dye vat and rotary cylinder, buckets in said cylinder
and gates, each pivoted at one edge near the inner edge of one of the buckets and
having its free edge toward the back of the adjacent bucket, substantially as described
and shown for the purpose specified.
7--In combination with the cylinder—C—,the dye vat having a segmental solid
bottom extending from the top of one side of the vat to the centre of the bottom
proper thereof, and a segmental perforated false bottom extending from the top of the
opposite side of the vat to the center of the bottom proper thereof, and a dye-liquor
receptacle back of said perforated bottom, substantially as described and shown.
