An Improved Method of and Apparatus for Effecting the Oxidation
of Aniline Black in the Process of Dyeing Cotton Thread or
Wool on Bobbins and Cops.
I, CARL SCHNÜRCH, of 11 Johannesstrasse, Altchemnitz, in the Empire of
Germany, Chemist, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of my invention is to effect improvements in dyeing cotton thread or
wool on bobbins and cops, by rapidly oxidising the aniline carbon dyes.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters and figures of reference indicate corresponding parts.
Fig. 1 is an elevation of the apparatus, with the side covering removed.
Fig. 2 is a plan view, with the top covering removed; and
Figs. 3 and 4 are detail views.
kk are two endless pitch chains; mounted upon suitable wheels, on each side of
the apparatus. These chains carry the bars 9 g, transversely to the chains; a side
view of one of the bars being shown in Fig. 3, and a part plan view in Fig. 4.
The bars g are fitted with spikes or pins ss, upon which the bobbins or cops co
are placed, and whereby they are carried through the apparatus.
By means of this apparatus continued working is effected, the bobbins or
cops c being placed upon the points s at the right hand end before passing the
wheels 1, 1, and removed when they arrive at the left hand end, after passing the
wheels 27.
The axles carrying the wheels numbered 1, 7, 13, 17, 23, 27, and 36, are extended
to the outside of the apparatus, and are there fitted with pitch chain wheels, to
which pitch chains m m are fitted. The axle carrying the wheels 13, 13, is fitted
with a worm wheel n. This is driven by the worm upon the vertical shaft w,
which latter is driven by disc gearing, as shown in Figs. 1 and 2, or otherwise.
t is the drying room and d is the damping room.
The chains k with the bobbins or cops, travel over the wheels 1 to 24 in the
drying room t, and over the wheels 24 to the damping room d. Here the chains k
pass over the wheels 25, 26 and 27; departing by the wheels 27 from the damping
apparatus. Here the bobbins or cops may be removed, the chains and bars passing
over guide rollers 28: under the drying room, over guide rollers 30, 31, 32, 33,
34, 35, then ascending again to the drying room over guide rollers 36, 37; over the
adjusting tension rollers 38 to the wheels 1, and into the drying room t.
The drying of the thread or wool, in the drying room t, is effected by heated air,
which is driven into the drying room t, through a tube o, by means of a fan y; the
moist air passing out through a flue .
In order to damp the material in the room or chamber d, boiling water is
supplied continuously to the cistern b, in the damping room d; the steam or vapour
passes through a sieve or perforated screen i, and then operates upon the material,
which is conducted or led by the chains k through the damping room d.
vapour escapes through the flue a.
The
The roof p of the damping room d, is cellular, and the plates are heated by
means of steam, admitted to the cellular spaces by the steam pipe r, the exhaust
being carried down to the cistern 6 by the pipe h. The water in the cistern bis
heated by steam pipes r and h. The drying and damping rooms or chambers are
entirely enclosed in wood, openings being only left for the bobbin chains k, with
the bars and bobbins to pass through.

page_text: 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. The improved process of drying and damping cotton thread or wool on
bobbins or cops, when treated with aniline carbon dyes, for the purpose of rapidly
oxidising the same; by fixing the bobbins and cops to rods carried by endless
chains, and thereby carrying the same through the drying and damping rooms,
and preventing the same from coming in contact with a foreign matter, sub-
stantially as herein before described and illustrated by the drawings.
2. The improved apparatus for continuously carrying on the aforesaid process,
whereby the bobbins and cops are placed on pins, pegs, or teeth, outside the drying
room t, and carried by endless chains through the drying room t, and damping
room d, and removed outside the damping room, while fresh materials are supplied
to the drying room, substantially as hereinbefore described and illustrated by the
drawings.
3. The improved method of and apparatus for effecting the oxidation of aniline
black in the process of dyeing cotton thread or wool on bobbins and cops,
substantially as hereinbefore described and illustrated by the drawings.
