Specification Accepted, 10th Feb., 1888
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 improvements in Dyeing Apparatus, and consists of the
novel construction and combination of parts hereinafter described and pointed out in
the claims.
The invention is to be considered as an improvement upon the apparatus shown and
described in U.S. letters patent No. 334. 793-issued January-26th-1886, to
A. Moran to which reference may be had.
The apparatus therein described consisted essentially of a dipping wheel or cylinder,
rotary in a vat, containing dye stuff and provided with perforated partitions for
carrying the fabric through the dye stuff, extending longitudinally of the cylinder,
and of a peculiar curved shape, in cross section the curve extending in a long sweep
from the hub, or a point near the axle to the periphery of the wheel.
This form of partitions caused the fabric to roll from a point, near the periphery of
the wheel, down to the hub, as it was lifted from the dye stuff, which more or less
entangled and knotted the fabric, instead of imparting to it a half revolution to bring
its sides alternately in contact with the carrying partitions, the result being that the
fabric was not dyed evenly.
To overcome the difficulty of rolling the goods, partitions having angular or
V-shaped pockets, to receive the fabric have been employed, but this form does not
wholly overcome the difficulty, as the inclination of the inner side wall of the V-shaped
pockets thus formed in the partition near the periphery of the wheel causes the fabric
to commence sliding or rolling therefrom before the pocket is vertically over the hub
or axle of the wheel and, as the wheel necessarily travels slowly, the fabric will

page_text: frequently be given a complete revolution in falling from the V shaped pocket, to the
center of the wheel.
I have ascertained that by giving the partitions approximately the shape of a sickle,
the part, representing the handle of the sickle, extending radially in an approximately
straight line about half the distance from the hub to the periphery of the wheel, and
the remaining distance in approximately the form of the blade of a sickle or semicircle,
the fabric will not start to leave the semicircular pockets until the radially straight
portion of the partition is nearly vertical, whereby only a semirevolution is imparted
to the fabric as it falls into the dye stuff below, or upon the back of the contiguous
pocket, which leaves it floating in the dye-stuff, to be again caught by the pocket
which has just dropped it, but with that side of the fabric which was previously in the
bottom of the pocket, now at the surface of the pocket, to be thoroughly permeated
by the dye stuff as the fabric is forcibly borne through it, by the moving pocket, the
operation being repeated at each rotation of the wheel.
Another feature of my invention consists in forming the pockets of round rods
extending longitudinally of the wheel, to present only rounded surfaces to the fabric
and insure uniformity of surface throughout the length of the pocket and thereby
uniform treatment of the fabric.
Fig. 1 of the drawings is a side elevation of my improved apparatus.
Fig. 2 is a central longitudinal section of my improved dipping wheel or cylinder.
Fig. 3 is a vertical cross section of the dipping wheel detached.
Fig. 4 is an end elevation of the apparatus shown in Fig. 1.
Figs. 5 & 6 are respectively longitudinal and transverse central vertical sections.
A represents the dipping wheel, and B-the vat, containing the dye-stuff, and
adapted to receive the lower part of the wheel.
The wheel is in the form of a cylinder made up of the two circular disks A-
constituting the heads of the wheel, or ends of the cylinder.
These heads are connected by the longitudinal rods A-forming the pockets a―in
the partitions band by a circular axle or hub A³.
The heads are provided exteriorly with suitable gudgeons or bearings A-rotary in
boxes A secured upon the end supports or heads of the vat.
One of the gudgeons may have a pulley A-fixed thereon, or other means, for
receiving power.
The partitions are made up of the round rods A'--with spaces between, and the
larger supporting rod a-all extending longitudinally of the wheel, from head to
head, and a series of short radial rods or slats b¹-with small spaces between, the
radial rods being supported at their outer ends by the longer longitudinal rod a²-and
at their inner ends by the hub A³.
These partitions divide the wheel into spaces, for receiving and carrying the fabric
to be dyed, dipping it into the dye-stuff on one side of the vat, carrying it through
the dye stuff in the vat, and lifting it therefrom on the opposite side of the vat, and
carrying it back to be again dipped at each rotation of the wheel.
The vat is preferably made of the heads B-having a semicircular channel F³-to
receive the ends of the staves F-F-forming the bottom and sides of the vat, and
held together by the threaded exterior rods H-passing through the heads and secured.
by nuts B by which the heads are drawn tightly together, the nuts and bolt heads
B³ resting upon the bearing plates B³.
The central bottom stave F-is made preferably thicker than the others, and
provided with a longitudinal channel Fadapted to receive the steam pipe C
provided with small escape holes C₁-opening into the dye-stuff in the bottom of the
vat, for the purpose of heating it.
By having the steam-pipe countersunk in the bottom of the vat, I am able to run
the wheel close to the bottom of the vat, and accomplish the operation of dyeing with
a minimum quantity of dye-stuff.
By forming the partitions bentirely of rounded rods arranged with spaces
between, the dyestuff is permitted to pass freely through the same, and the fabric
cannot be cut or injured by contact with sharp edges.

page_text: By having the rods, forming the inner portion of the partitions extend radially, the
fabric slides easily to, or from, the periphery of the wheel, should it come in contact
with the same in passing to and from the pockets a. By having the pockets a―
semicircular in shape, substantially as shown, with the inner side-wall of the pockets,
at their mouths about right angular to their respective radial partitions, of which they
form an extension, I am able to repeatedly dip the fabric in the dye-stuff, and reverse
the position of the fabric in the pockets, at each rotation of the wheel, without snarling
or knotting it.
By employing pockets, the cross sectional form of which is curved or rounded,
instead of angular or V-shaped, the fabric is not liable to become wedged in the
bottom of the pockets and be carried around with the wheel without falling out ;
thereby securing a positive reversal of the position of the fabric, relatively to the
pockets, at each rotation of the wheel, and consequent uniformity in distribution of
dye-stuff through the fabric.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is
First In a dyeing apparatus, the combination with a dipping wheel, rotary in a
dye-vat, and provided with radial partitions; of pockets formed in the partitions,
approximately semicircular in cross sectional form, and having their inner side-wall,
at its point of junction with a partition, approximately right angular thereto,
substantially as described and for the purposes set forth.
Second In a dyeing apparatus, a dipping wheel, or cylinder, rotary in a dye-vat,
consisting of two heads, provided with bearings and connected by a hub, radial
partitions, and longitudinal pockets, said partitions consisting of rows of pins, or rods,
projecting radially from the hub to the several pockets, at points about half way
between the hub and periphery of the wheel, the pockets consisting of rounded rods
extending longitudinally from head to head of the wheel, and having a cross-sectional
arrangement approximately in the form of a semicircle, the inside wall of the
respective pockets, at its point of junction with the rows of radially projecting pins,
being approximately right angular to said pins, substantially as described and for the
purposes set forth.
Third In a dyeing apparatus, the combination with a rotary dipping-wheel or
cylinder, having radial partitions of a wheel-supporting dye-vat provided with a
bottom, semicircular in cross sectional form, and having a channel or groove, formed
at the lower part of the inner side of the bottom; and a steam-supply pipe located in
said groove, and opening into the vat, substantially as and for the purposes set forth.
Dated this 10th day of January 1888.
