COMPLETE SPECIFICATION.
Apparatus for Dyeing and similarly Treating Textile Rovings.
I, RICHARD BRANDTS, Manufacturer, in Murfchen-Gladbach, in the Kingdom
of Prussia, part of the German Empire, 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:—
This invention has reference to apparatus for dyeing, bleaching and otherwise
similarly treating with fluids, textile rovings or slubbings, when wound upon
bobbins. In the type of machine or apparatus to which this invention relates,
the barrels of the hobbins, upon which the textile rovings are wound, are per-
forated, and the fluid with which the rove is to be treated is caused to pass through
these perforations into and through the surrounding roves without tearing or
otherwise injuring the rovings.
I will describe my present improvements with reference to the accompanying
drawings in which:"
Fig. 1 represents a longitudinal section;
Fig. 2 a plan,
Figs. 3 and 4 views of the cop or bobbin arranged for treatment and surrounding
shell,
Fig. 5 shews the means for attaching the shaft E and the surrounding shell
and
Figs. 6 and 7 plans of Figs. 5 and 6.
The bobbins upon which the rove is wound, have conical lower ends e which fit
into corresponding conical holes in the plate C, which is placed upon projections k
of the tank B being secured by small rubber washers, so as to fit air tight and
creating a kind of double bottom between it and the bottom of the tank. Each
of the bobbins E upon the plate is surrounded and enclosed by the cylinder F
of copper or other suitable material, which fits in all sides closely over the bobbin
and is attached by a tight joint with the plate C. This attachment may be
effected by screwing the lower ends of the cylinders on bosses e concentric with
the bobbin E. The cylinder may advantageously be constructed of sheet copper
and so connected with the plate C that the liquid is forced from the inside to the
outside of the cylinder.
This
The cylinder F as well as the shaft E are pierced with a number of small
holes s the diameter of the openings in the mantle F being considerable smaller
than those of shaft E, of the bobbins through which the fluid is forced. Hence,
when the fluid passes outwards from the bobbin it cannot escape freely through
the holes in the cylinder which thus originate and maintain a back-pressure,
which adds to the momentary pressure of the fluid throughout the rove.
fact is of great value and it is found in practice to cause the prevention of spots,
shading and inequalities, in the treatment of the rove, whilst it also minimises
risks of damage to the rove during the process. The bobbin-shaft E may be coni-
cally shaped at its lower extremity 7 so as to tightly fit into the plate C while a
ring > soldered to the inside of the upper portion of said hollow shaft E serves
as a guide to steady the shaft upon the spindle.
The plate C can be lowered into the tank B by means of a crane chain and

page_text: hook engaging with the eye-bolt D, until it rests upon the projections K on the
inside walls of the tank. The joint between the plate and tank can then be made
tight with packing G. The injection of the fluid by the pump A is made through
the inlet L, to the space below the plate, whence it passes through the openings h
of the shaft E to the rove thereon and away through the small perforations of
the cylinder F.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1). In apparatus for dyeing textile rovings a perforated bobbin shaft for the
introduction of liquid, a perforated outer cylinder having smaller perforations
than the shaft E and being secured air tight to said shaft.
2), In apparatus for dyeing textile rovings a perforated bobbin shaft, an outer
cylinder having smaller perforations and being secured air tight to shaft E, in
combination with a bottom plate G having holes for the introduction of bobbin
shaft E and for passing the liquid into it, a tank B having projections K for
securing the bottom plate G and means for introducing the dyeing liquor into
the chamber formed by the plate G and the bottom of the tank.
