PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Dyeing Woollen
Cloths and other Fabrics.
1 JOHN WILLIAM HEPWORTH, of Churwell, near Leeds, in the county of York,
Dyer, do hereby declare the nature of this Invention to be as follows :—
My improvements consist in employing a suitable partition across the cistern for
keeping back the cloth from immediate contact with the steam pipe employed for
boiling the liquid.
The said partition being fixed so as not to make a watertight compartment but to
allow a free circulation of the liquid in the cistern.
In some cases it is desirable that the cloth should not rest the whole time in the
liquid subject to the direct action of the steam I therefore provide a sloping back or
scray terminating with a semicircular or rounded end to suspend the cloth until its
turn comes to pass through the boiling liquid in the cistern below through which it
passes over guide rollers in a fairly extended or opened out state over the winch and
by means of a drawing roller and cutter again onto the scray and so on continuously
the cloth being opened by a workman in front.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Dyeing Woollen
Cloths and other Fabrics.
I, JOHN WILLIAM HEPWORTH, of Churwell, near Leeds, in the county of York,
Dyer, 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 improvements consist in employing a suitable partition across the dye cistern
for keeping back the cloth from immediate contact with the steam pipe employed in
boiling the dye liquid.
The said partition being fixed so as not to make a watertight compartment, but to
allow a free circulation of the liquid in the said cistern.
In some cases it is desirable that the cloth should not rest the whole time in the
liquid subject to the direct action of the hot dye liquid. I therefore provide a
sloping back or guide scray terminating with a semicircular or rounded end to
suspend or hold back the cloth until it comes to pass through the boiling liquid below
in the cistern through which it passes over guide rollers in a fairly extended or
opened state over the winch, and by means of a drawing roller and cuttler again
onto the said scray, and so on continuously, the cloth being "opened" by a workman
in front.

liquid to float where the bulk of the cloth is situated.
D is a winch or roller for drawing the cloth out of the cistern B, and for actuating
the automatic drawing or conducting rollers E, E. the roller F being driven by a
strap or chain from end of the winch or roller D. G is the steam pipe, provided
with a valve or cock G', for introducing steam into the cistern B. H indicates the
cloth.
Fig. 3. I employ a sloping back or guide scray A' having a semicircular or rounded
end A, for suspending or holding back the cloth until its turn comes to pass through
the dye liquid in the cistern B.
D is a winch or roller for drawing the cloth out of the cistern B, and for actuating
the drawing or conducting rollers E, E, E, E, E. F is roller driven from winch
or roller DT by means of strap or chain, H indicates the cloth and J the cuttling
roller.
The said sloping back or guide scray A'may be made adjustable to suit the quantity
and weight of the cloth being dyed.
When steam is blown into the usual form of dye cistern it knocks the cloth about
violently and prevents the workman from "opening" the picco straight, which is
very important, particularly in heavy goods. It will be seen that, according to my
invention the cloth being behind the partition A (see Fig. 1.) is protected from this
violent disturbance, and when it does come in the vicinity of the steam pipe, it is
there held in tension betwixt the rollers E, E.
It will therefore be seen that the said partition materially assists the "opening" or
keeping straight of the cloth.
Having now particularly described 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 is
1. The employment of the partition A in combination with the winch or roller D
as and for the purposes shown and described.
2. The employment of the sloping back or guide scray A' in combination with the
winch or roller D₁ as and for the purposes shown and described.
