I LORENTZ. ALBERT GROTH K.G.V, Civil Engineer and Managing Director of
the Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London EC. do hereby declare the nature of the said Invention for
A NEW OR IMPROVED APPARATUS FOR AND METHOD OF CHEMICALLY TREATING
WOOL COTTON AND OTHER SOFT GOODS a communication to me from abroad by
Henry Giesler Gentleman of Molsheim Elsass in the German Empire to be as

The object of this invention is the chemical treatment of wool cotton and other
soft goods for different purposes such as dyeing bleaching washing &c.
The apparatus consists of a reservoir for the fluid a pump and a receptacle for
the material to be treated Pipes for the circulation of the fluid are led into the
bottom of this receptacle, into which perpendicular pipes with perforated sides are
inserted. Bobbins or reels containing the fibres or fabrics to be operated upon are
placed on these pipes and a small disc placed between and close to each These pipes
are all connected to one main pipe connected to the pump and the reservoir which
is also connected to the receptacle by a return pipe.
t
When the bobbins or reels are in their places the fluid is turned on and soon fills
the circulating pipes passing through the perforated pipes and the bobbins with the
material thereon till the fluid finds its level: The stop cock is then reversed
shutting off the flow and the pump by means of a suction pipe returns the fluid to
the reservoir This action will begin as soon as the fluide reaches the 'lower end of
the suction' pipe but can be reversed by drawing it through the material and the
circulating pipes through which it entered.
i7"
The pump can be used as a force pump to press the fluid but the suction gives
better results.
The perforated pipes are covered or closed at the top by moveable caps and the
perforations are larger at the bottom than at the top.

page_text: I LORENTZ ALBERT GROTH, K.G.V. Civil Engineer and Managing Director of
the Universal Inventors' and Patentees' Financial Company, Limited, 30 Finsbury
Pavement, E.C., do hereby declare the nature of the Invention for "A NEW OR
IMPROVED APPARATUS FOR AND METHOD OF CHEMICALLY TREATING WOOL, COTTON
AND OTHER SOFT GOODS" and in what manner the same is to be performed, as
communicated to me from abroad by Henry Giesler, Gentleman, residing at
Molsheim, Elsass, Germany, to be particularly described and ascertained in and by
the following statement:-
T
This invention relates to the chemical treatment, i.e. the dyeing, bleaching,
washing, mordanting, steaming, oxydizing and drying of wool, cotton and other
'fibrous material in the form of slubbing, rovings. or slivers, and it substantially
'consists in placing the said material in coils around a perforated pipe, and in
forcing or drawing the operating fluid through the pipe and its perforations and
through the material, a movable bead or cap being placed on the top or end of the
said pipe, adapted to close or cover the perforations of the same which are
uncovered by material.
r
The apparatus which I employ for this purpose is represented on the annexed
sheet of drawings by Fig. 1 in sectional elevation, and by Fig. 2 in plan. Figs. 3
and 4 are modifications of a part thereof. a is a reservoir for the fluid, b a pump,
and ca receptacle in which the material is treated. At the bottom of the receptacle c
are arranged pipes or boxes d, connected by means of pipes e and f to the pump b
and the reservoir a. Besides, the latter communicates with c by a pipe t. The
aforesaid perforated pipes g are inserted with their lower end into the pipes or
boxes d, which, for this purpose, are provided with suitable apertures, preferably
fitted with short funnel-shaped attachments h, serving to facilitate the insertion of
the pipes g. is the material coiled around the latter or previously prepared so as
to form coils or bobbins which are slipped over the pipes. These coils or bobbins.
are carried by disks / fixed to the pipes g, and they may be maintained separate
from each other by means of disks; inserted between them. I m are the heads or
caps placed over the top of the pipes g and movable thereon, the part 1 serving by
its weight to compress the coils i, while the tubular part m has the object to keep
covered or closed the perforations of the pipes g being above the coils, so as to
prevent fluid from being drawn through them. These heads or caps follow the
material as it settles during the process and thus ensure that the whole mass of
fluid which is drawn or forced through the tube g, will pass through the material
under treatment.
When the pipes i with the bobbins or coils of material on them, are in their
places, the fluid contained in the reservoir a is turned on by the cock n, so that it
will pass through the pipes f, e and d, the perforated pipes g, and the material i,
and run into the receptacle c. After it has attained within the same the required
level, communication between c and a is stopped and between c and the pump b

page_text: established, whereupon the pump is put in motion and a circulation of the fluid
through the material and the pipes g, d and o produced in contrary direction.
The pump may also be arranged to force the fluid through the material, but the
method of drawing it through the same, as described, is preferable.
Fig. 3 shows an arrangement which is an inversion of the foregoing, the disk
being attached to the perforated pipe g, while the tube m is fixed to the disk k, the
pipe g in this case sliding in the tube m, which is stationary.
The pipe g may also be placed horizontally, as in Fig. 4, the disk 7 being, with
this arrangement, maintained in contact with the material i by the pressure of
the fluid resulting from the sucking action of the pump.
The fluid to be employed varies according to the nature of the effect to be
produced. In case the material is to be dried, the pipes with the coils on them are
placed in a heated chamber and the lower ends of the same connected with an air-
exhauster.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, as communicated to
me by my correspondent, I declare that what I claim is
The method of dyeing, bleaching, washing, mordanting, steaming oxydizing and
drying wool, cotton and other fibrous material in the form of slubbing, rovings or
slivers, by placing the said material in coils around a perforated pipe g and
between two disks k and I, one of which is movable on the pipe and provided with
a tubular part m, adapted to cover and close the perforations at the free end
thereof, substantially as and for the purpose specified.
