A New or Improved Apparatus for use in Treating Textile Materials
and the like with Liquids.
I, WILHELM SCHMIDT, of 23, Herrenstrasse, Mühlhausen, Thuringia, Germany,
Manufacturer, 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 relates to a new or improved apparatus for use in the treatment
of textile materials or fabrics and the like with dye liquors or other liquids, by
placing the said materials upon a perforated bottom or grating, suitably disposed
and supported at convenient distance from the vat-bottom proper, so that the
respective liquid poured upon the material may thoroughly penetrate and percolato
through the same from above and then collect in the space or chamber, formed by
the aforesaid perforated bottom and the proper bottom of the vat, whence it can
be raised, by means of a conveniently arranged pump or the like, and again be
poured over the surface of the layers of material under treatment.
In the drawing hereto attached three different forms of construction of
apparatus forming the subject of the present invention are illustrated, but other
construction may be employed for attaining the same object of passing the dye
liquors or other liquids repeatedly onto and through the material under treatment
and then again collecting it for further use.
Fig. 1 illustrates a device essentially consisting of a vat or tank a provided
with a suitably disposed and supported and perforated bottom or grating b
upon which the material under treatment is to be placed in layers.
Below the bottom there is a chamber d intended for collecting the liquid
that has passed through the material under treatment, and a pump e of any
suitable construction is provided for the purpose of re-conveying the liquid to the
uppermost layers of material. The drawing shows the disposition of the discharge
pipe of the pump in the centre of the vat, but it may also be placed outside the
latter or disposed in any other convenient manner.
Fig. 2 shows a similar device in a vat or tank a divided by means of vertical
partitions f radiating from the centre into two or more separate compartments
which communicate with each other, below the perforated bottom or grating b
through apertures so that the liquid, after passing through the material under
treatment, can collect in chamber for reconveyance to the surface in the manner
before described.
In this case the discharge pipe e of pump is provided with a moveable head
piece or nozzle for the purpose of admitting the liquid being discharged in
different directions into the various compartments of the vat or tank. The draw--
ing illustrates one method of arranging the moveable pump spout, but any other
contrivance suitable for effecting the same purpose may be employed.
The separate compartments formed in one vat or tank as above described and
illustrated in Fig. 2 of the drawings, may be replaced by several separate vats or
tanks ar (Fig. 3) each having a perforated bottom or grating for the previously

page_text: described purpose; in this case a separate vessel d for collecting the liquid from
the different vats is provided and made to communicate by means of pipes h
with each of the vats; a pump c of any convenient constructions and provided
with a moveable nozzle e is made to serve for the reconveyance of the liquid onto
the material under treatment in the different vats or tanks.
The pipes entering the common collecting vessel d immediately above the
bottom of the latter are continually kept hermetically closed by the liquid. In
the aforesaid arrangement of separate vats, the pipes h, communicating with the
collecting vessel d, may, as shown in the drawing, be furnished with stop-cocks
or valves for the purpose of reserving exhausted liquor while the circulation is
being maintained. and the exhausted liquor be refreshed, by fresh liquor or dyes
introduced into the vats..
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) In apparatus for use in treating textile material, fabrics or the like with
liquids, in which the material to be treated is placed upon a perforated bottom or
grating suitably disposed and supported within the vat or tank, the application
of a conveniently designed pump either without or provided with a moveable
discharge nozzle or spout for reconveying to the surface of the material under
treatment the liquid collected in chamber below the perforated bottom or
grating substantially as described and illustrated in the accompany drawings.
2) In apparatus for use in treating textile materials, fabrics or the like with
liquids, as claimed under 1) the arrangement of various compartments in one vat
or tank, each compartment being designed to receive material for treatment, and
communicating below the perforated bottom or gratings with a common chamber
for collecting the liquid after percolating through the material under treatment,
substantially as and for the purpose described and illustrated in the accompanying
drawings.
3) In apparatus for use in treating textile materials, fabrics or the like with
liquids, as claimed under 1) the arrangement of a series of separate vats or tanks
for receiving material for treatment, the chambers underneath the perforated
bottoms or gratings & communicating with a common collecting vessel through
pipes, which may, when required, be provided with stop-cocks substantially
as and for the purposes set forth and illustrated in the accompanying drawings.
Dated this 3rd day of March 1899.
