Improvements in Dyeing, Washing, and Rinsing Apparatus for Textile
Goods.
I, HEINRICH SCHIRP, of Barmen, Rhenish Prussia, Wichlinghauserstrasse 12,
Engineer, 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 relates to dyeing, washing and rinsing machinery for textile goods,
and has for its object to enable the machine to force the mordant liquors or any
other liquid used for treating wool and other textile fibres in raw or prepared state,
effectually through the goods contained in a special tub or closed vat in such a
way, that either by suction or by pressure a continuous circulation of the said
liquors or an alternated forcing circulation and suction circulation respectively, in
the one or the other direction be effected for a determined period, and that fresh
unexhausted liquor be brought to work upon the interior strata of the goods in the
vat, as well as upon the exterior strata thereof, all strata being thus exposed to the
respective operation during equally long periods.
In both cases, of suction as well as of forcing circulation through the material,
the liquor used for the treatment of said goods is taken from a special vessel or
reservoir and is returned to the same. In the suction case the liquid is sucked across
through the goods in the vat, and then returned into the reservoir; in the forcing case
the liquid is sucked from that vessel first and then forced through the goods and
back into the vessel.
For attaining these objects, I provide the pump which is intended to do the
circulation work of the respective liquor, with a forked: tube immediately behind
the rear cylinder cover which is open. Each branch of this pipe is provided with
a cock or valve of special construction, the cone of which can be turned in it's
housing wholly round, and which contains in its passage a valve. This latter can
act as a suction valve or as a force valve, according to the. position given to it by
the turning of the cone containing it. By this simple arrangement, I obtain the
desired effect to force the liquor through the goods either by suction or by pressure,
in reversing the cocks with the valves in them, in the two branches. hifurcating
at the pump end. The result of this arrangement is an intense utilisation of the
active matters in the liquors, or of the dye in dyeing, so that a thoroughly
regular and equally perfect saturation of the goods is effected. In the same manner
the goods may be submitted to an impregnating operation with liquid chemicals, to
rinsing with water and such like.
The effect of uniform repartition of the employed liquor in the goods, so. that a
simultaneous action of it may take place throughout the whole mass undergoing, the
treatment in the vat, is further improved by. the insertion of perforated cones. or
pyramids into the inner part of the goods contained in the vat and by arranging
them according to the requirements of the respective goods.

The pump plunger A works in a cylinder B, and D is a vat or dyeing cylinder

page_text: placed in its plug which may act as a suction valve or as a force valve according to
the position of the plug, the tube H leading to the bottom of the vat and H' into the
vessel E; a tube R connecting the top part of the vat D with the vessel E; a fixed
perforated bottom C being placed in the lower part of the vat and a movable cover N
at its top to allow the passage of the liquid into the textile material either by suction
from the top or by forcing it from below; perforated funnels C C and N N being
respectively placed above or below the perforated bottoms C and N in order to admit
fresh liquid into the interior or central parts of the material under treatment, the
whole as specified and for the purpose set forth.
2. In a machine as specified in Claim One a reversible combined cock and check-
valve, the plug of the cock forming the casing of the valve which is placed in the bore
of the plug, so that by turning the plug by 180 degrees the valve may act as
a suction valve or as a forco valve in respect to the pump connected to one side
of the cock.
