1, EDWIN BOOTH of 75 Oxford Street Old Trafford, Manchester in the County of
Lancaster, Clerk, 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:
-
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a vertical section. Fig. 2 a side view of the apparatus and Fig. 3 a plan
of the vessel.
This invention relates to improvements in apparatus for dyeing loose or spun cotton
or other fibres, other colours than black, and consists of a vessel A made of copper,
sheet iron or cast iron, strong enough to withstand the outer pressure of the atmosphere
against an internal vacuum.
The vessel A can be opened and closed by means of a cover B formed with a dome b,
provided with an air cock a, gauge-glass c, and vacuum gauge d.
In order that the cover B will fit hermetically onto the vessel A, the flange e of the
cover B, is furnished with a packing ring d'.
The bottom C of the vessel A is formed with a suitable number of passages f which
incline to the centre from the interior of the vessel A, and are in communication with
the perforated pipes D fitted in any desired position, in one or more rows in the
interior of the vessel A.
The centre of the latter is also provided with a perforated pipe E, the lower end of
which is formed conically, & rests in a conical socket g, from which it may be
removed, when the vessel A is turned over.
The perforated pipes D & E, serve to equally distribute the fluid which flows through

page_text: the leather pipe h, and passages f, on opening the cock i, from the reservoir F, into
the vessel A.
In lieu of employing perforated pipes Das and for the purpose described, the
vessel A may be formed with a double wall, the inner one being perforated.
The vessel A is provided with a perforated false bottom K, which prevents the
escape of the cotton in the vessel A, when the discharge cock, see Figs. 2 & 3, which
is in communication, with the interior, is opened.
By means of the crane G, capable of revolving round the pivots k, the cover B of
the vessel A can be raised by pressing on the lever V, and moved on one side by
turning the crane G round the pivots k.
The dome 6 of the cover B is connected by means of the hose pipe l, with an air
pump or steam jet exhauster, or other suitable apparatus, by which will be produced a
vacuum in the vessel A.
The latter is provided with pivots m, and rests in the supports H, and can be turned
round by means of the hand wheel n, and worm o, and worm wheel p, for the purpose
of emptying the contents of the vessel A.
The operation of the apparatus is as follows:-
The reservoir F is filled with the requisite solution and the vessel A charged with
the cotton or other fibres, to be dyed, the cover B is then closed, and a vacuum
produced in the vessel A, through the medium of the pipe l, and a pump, steam jot
exhauster, or otherwise.
When the gauge C indicates that the vacuum in the vessel A is sufficiently strong
the solution is let into the vessel A by opening the cock i and when filled with it, the
çock is shut and the air allowed to enter the vessel A by means of the cock a.
The cover B is then removed by depressing the lever and by turning the crane G,
and the greatest part of the solution in the vessel A is let out, by the discharge cock it,
see Figs. 2 & 3, into the reservoir F, & the cotton or other fibres emptied onto
the gratings, I, fixed partially over the reservoir F by turning the apparatus into
the position shown in Fig. 2, at the same time discharging the solution into the
reservoir F.
.
I am aware that previous to this invention similar apparatus for dyeing cotton black
have been used, but what I claim, is :-
The application of the apparatus constructed and operated as hereinbefore described,
for dyeing cotton or other fibres other colours than black, substantially as set forth.
