0 Hi I Patented May 20, 1952 SUCTION HYDROEXTRACTOR Curt Jellinek, ounty of Glamorgan, Wales, now by judicial change of name Curtis Marcell Elliot Application April 4, 1946, Serial No. 659,450 In Great Britain April 16, 1945.

This invention relates to'improvements in hydro extractors for the treatment of textile fabrics.

In the following specification and claims the term hydro-extractor is intended to cover not only apparatus for and the removal of 'water but also for the removal of other liquids and similarly the term hydro-extractions is intended to cover the removal of Water and other liquids.

The bleaching, dyeing and finishing of textiles usually takes place in water or other liquid medium and after most of the operations connected with these processes the liquid has to be removed therefrom. This is done as far as possible by mechanical means and the remaining liquid is removed by evaporation in drying machines which use heat. Such mechanical drying means include hydro-extraction and mangle's. Mechanical drying by hydro-extraction may be carried out in various Ways e. g. by centrifugal hydro extraction, which is eificient but does not work continuously and may damage delicate fabrics and by suction hydro-extraction which hitherto has only been used for goods in full width and can therefore not be used for continuous processes, where the goods are treated in rope form. In many continuous processes fabrics are treated in rope form and if the liquid has to be removed between each process only the mangle is available which as stated is unsuitable for delicate fabrics.

'I'he object of the present invention is a device which will permit the continuous suction hydroextraction of fabric in rope form without damaging the fabric, which can be applied under most conditions, fitted to existing machines or used as a separate unit.

The suction hydro-extraction device according to the invention consists of a short length of round, oval or other shaped tube provided with one or more apertures, slots or series of perforations at one or more areas of its surface the aperture or apertures or slots or perforations being connected to a vacuum pump or other source of suction preferably through a water separator.

The invention is illustrated diagrammatically in and will be described with reference to the accompanying drawings which show several embodiments of the invention. In these drawings:

Fig. 1 is an elevation of a simple form of the invention, including the suction producing means;

Figs. 2 and 3 are a sectional elevation and sectional plan respectively of a form of the invention wherein the tube is formed with a single slot, the area of the tube where the slot is located being surrounded by a jacket;

3 Claims. (01. -306) Figs. 4 and'5 are an elevation and a sectional plan respectively of a form of the invention wherein the tube is formed with a plurality of perforations, the area of the tube where the perforations are located being surrounded by a jacket;

Fig. 6 is a perspective sectional view of a form of the invention'similar to that shown in Figs. 4 and 5 showing a fabric in rope form being drawn through the device by a roller.

In all the forms of the invention A is the tube through which the fabric is passed in rope form and B is the suction pipe which is connected to a suction or vacuum pump H by a pipe h, the pump exhausting through the pipe 71, as shown in Fig. 1.

Fig. 1 shows the simplest form of the invention in which a single aperture (1 is" formed in the bottom portion of the tube A and is enclosed by a jacket C which communicates with the aperture, and the suction pipe B is connected to the jacket 0 on the tube A.

Figs. 2 and 3 are detail .views of the tube A formed, as shown in Fig. 1, with a single slot (1 in the bottom portion of the tube, the area of the tube in which the slot is formed being enclosed by the airtight jacket 0 to which the suction pipe B is connected. Instead of a single slot a as shown in Figs. 1, 2 and 3, two or more apertures or slots may be formed in the bottom portion of the tube A all the slots being enclosed by a single jacket.

Figs. 4 and 5 show the tube A formed with a plurality of perforations a in the lower portion, the area of the tube in which the perforations are located being surrounded by the air tight jacket C to which the suction tube B is connected.

In the previously described forms of the invention the aperture or slot oi or perforations a are formed in the lower portion of the tube A and a single suction pipe B is connected to the lower part of the jacket C surrounding it.

The operation of the device is illustrated by Fig. 6 which shows a length of fabric D in rope form being drawn through the tube A by the.

driven roller E, whilst suction is continuously applied to the pipe B, which causes air to enter each end of the tube A.

Although in the various figures of the drawings the tube A is indicated as being circular in cross section it may be of oval or any other suitable shape for the passage of the fabric in rope form, and it may made of any suitable material such as metal, glass or synthetic glass or syntheticresin.

The device comprising the tube A and suction pipe B and the suction or vacuum pump con- 3 nected to the pipe B may be carried on a moveable platform to constitute a self contained unit or the pump may be separate from the device and suitably connected thereto in which case a single pump can serve a number of tubes.

By using a suitable suction or vacuum pump the device will hydro-extract the fabric passing through it to the same extent as a full width suction hydro-extractor.

I claim:

1. A suction hydro-extractor for the treatment of textile fabrics comprising a tube open at each end for the passage of the fabric in rope form and entrance of air, an air tight jacket enclosing a portion of the periphery of said tube, the jacket being in communication with the interior of the tube, a suction pipe connected to the interior of the air tight jacket, and suction producing means connected to said suction pipe.

2. A suction hydro-extractor for the treatment of textile fabrics comprising a tube open at each end for the passage of the fabric in rope form and entrance of air, an air tight jacket enclosing a portion of the periphery of said tube, the jacket being in communication with the interior of the tube through an aperture in the wall of the tube, a suction pipe connected to the interior of the air tight jacket, and. suction producing means connected to said suction pipe.

3. A suction hydro-extractor for the treat- 4 ment of textile fabrics comprising a tube open at each end for the passage of the fabric in rope form and entrance of air, an air tight jacket enclosing a portion of the periphery of said tube, the jacket being in communication with the interior of the tube, a suction pipe connected to the interior of the air tight jacket, suction producing means connected to said suction pipe, and means for drawing the fabric through the tube.
