Improvements in and connected with Vessels for Dyeing Purposes.
I, BENJAMIN LEE, of Woodhouse Dyeworks, in the City of Leeds, Finisher, do
hereby declare the nature of this invention to be as follows:-
According to my invention I employ a vessel or chamber (for holding the dyeing
liquor and materials) made of iron, steel, or other suitable material, and is covered
in the inside or lined with lead or other suitable material. Surrounding the said
vessel or chamber is an outer vessel or chamber made of iron, steel, or other suitable
material, forming a steam jacket for the inner vessel, the said jacket extending to
within a suitable distance of the top of the inner vessel. The outer vessel or steam
jacket is provided with a pipe by which live steam can be passed into it to boil the
liquor or inner vessel, the temperature of which is kept up by passing through a
pipe the exhaust steam from the cylinder of a donkey" or other engine or boiler
to which the said outer chamber or live steam pipe is connected, the live steam
being cut off by a valve when it is desired to use the exhaust, guages being provided
to indicate the pressure, so that should the pressure be excessive, a valve is opened
and the excess blown away through a pipe out to the atmosphere or carried away
for other use.
The vessel is provided with a cold water pipe which passes over the top of the
vessel for filling purposes, and a winch arrangement as ordinary. The steam
jacket, or outer vessel is also provided with vacuum pipes.
By the use of my invention a great saving in steam is obtained, also by the
method of boiling by means of the steam jacket, the steam is prevented from
coming in contact with the liquor, the boiling is also effected more rapidly, and
is under perfect control by the operative.

COMPLETE SPECIFICATION.
Improvements in and connected with Vessels for Dyeing Purposes.
I, BENJAMIN LEE, of Woodhouse Dyeworks, in the City of Leeds, Finisher, 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 has reference to improvements in aud connected with vessels for
dveing purposes.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional end elevation of dyeing apparatus or vessel constructed
according to my invention.
According to my invention I employ a vessel or chamber A (for holding the
dyeing liquor or materials) made of iron, steel, or other suitable material, which is
covered in the inside or lined with lead, or other suitable material B. Surrounding
the said vessel or chamber A is an outer vessel or chamber C, made of iron, steel,
or other suitable material forming a steam jacket for the inner vessel, the said
jacket extending to within a suitable distance of the top of the inner vessel A.
The outer vessel or steam jacket C is provided with a pipe D by which live steam
can be passed through branch pipe D' into it to boil the liquor in the inner vessel A,
the temperature of which is kept up by passing through the branch pipe D2 the
exhaust steam from the cylinder of a "donkey" or other engine or boiler, to which
the said outer chamber or live steam pipe D is connected, the live steam being cut
off by a valve E, when it is desired to use the exhaust, F being the exhaust valve.
Guages G are provided to indicate the pressure, so that should the pressure be
excessive a valve is opened and the excess blown away through a pipe out to the
atmosphere, or may be carried away for other use. An ordinary valve and pipe
are used for this and arranged at any convenient position.
The vessel is also provided with a cold water pipe which passes over the top of the
vessel for filling purposes, and a winch arrangement with driving gear and other
parts, all of which are as ordinary and in common use with dyeing vessels.
The steam jacket or outer vessel is also provided with vacuum pipes.
His the outlet of the vessel. The steami inlet to the jacket may be arranged at
any convenient position.
By the use of my invention a great saving in steam is obtained, also by the
method of boiling the liquor by means of the steam jacket the steam prevented
from coming in contact with the liquor, the boiling is also effected more rapidly,
and evenly throughout the vessel, and is under perfect control by the operative.
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. A vessel, for dyeing purposes, comprising a lead or other suitably lined
inner vessel having a steam jacket, whereby the dyeing liquor is boiled without
steam coming in contact with the dyeing liquor and evenly throughout the vessel,
substantially as set forth.
2. In dyeing, the use of a vessel externally heated by steam for boiling the
dyeing liquor, whereby the steam is prevented from coming in contact with the
liquor, and the boiling is evenly effected throughout the vessel, substantially as set
forth.
