Patented Apr. 25, 1939 UNITED STATES PATENT orrlca 2,155,494 WRINGING DEVICE Wilhelm Hermann Kober, Dusseldorf, Germany Application October 25, 1935, Serial No. 45,832

In Germany May 6, 1935 4 Claims. (01. 15-200 Several embodiments of the invention are illustrated in the accompanying drawing, in which Figure l is a top view of line A-B, of Fig. 1;

gitudinal section on the line E-F, of Fig. 3; Fig. 5, a top view of another embodiment of the in-, vention; Fig. 6, a top view of an additional plate forming part of the wringing means.

Referring to shown in Figs. 1 and 2 comprises two plates l and 2 made of metal, aluminum, etc. Corresponding to the shape of the wringer plate 3, the front end of both plates i and 2 is rounded off in a semicircle and the rear end thereof provided, respectively, with a flange 4 and 5. The lower flange has holes for the reception of the screws '6 for securing the device to buckets, tubs, etc. The actual wringer plate 3 of circular form consists of rubber and is provided with a hollow space i and a central opening 8. The hollow space 1 is open at the circumferential sides of the plate 3 and closed. towards the hole 8 so as to form a wall around the latter. Within the space 1 spiral springs 9 are radially. arranged, one endv of which is secured to the frame of the device by means of the pin ill and the other end abuts against the wall of the opening 8. The location and disposition of said springs within the opening being thus so as to exert pressure upon the surrounding wall of the opening 8, thus tending to close the said opening, whilst on an article be-' ing drawn through the said opening said springs offer resistance to ready expansion of the opening. The wringer plate 3 is secured within the frame by the grub screws Ii. Both plates l and Zhave a central round opening I! whose diameter is larger than that of the objects to be wrung out by being passed through the apertured wringer plate 3.

While an article is wrung out by being drawn through the apertured wringer plate 3 the spiral the drawing, the construction tured wringer member comprising springs 9 press against the wall of the central aperture and thus increase the pressure.

Referring to Figs. 3 to 5, a modification of the cuts H, a cloth to be drawn-through. In order to prevent ready tearing of the material of the wringer member 3 at the ends of said cuts edge of which slot-like aperture may also be reinforced by an annular bead to prevent ready tearing of the wringer member material on a cloth being drawn through said aperture.

At a convenient distance from the edge of the aperture, and according to the shay-T thereof, i. e.

cloth drawn through said aperture.

I claim:

1. A device for wringing wet fabrics consisting of 'a frame with an apertured wringer member of resilient material mounted therein, said wringer member comprising a disc with a fabric receiving aperture therein and auxiliary means disposed about the fabric receiving aperture for augmenting the pressure of said resilient wringer member upon the article to be wrung out during the wringing operation due to the expansion-of said aperture in use and means for supporting said frame.

2. A device for wringing wet fabrics consisting of a frame with an apertured wringer member of resilient material mounted therein, said apera disc with a fabric receiving aperture therein and having a hollow space open on the peripheral sides of said disc and closed towards the aperture to form a wall around the latter, auxiliary spring means disposed about the fabric receiving aperture for the article to be' augmenting the pressure upon wrung out and located in said hollow space, said spring means being secured onto the frame and position by vulcanizing, in the material around the aperture of the wringer member, thus tending to prevent ready expansion of the central wringer member portion encircled by said spring means, and means for supporting said frame.

4. A device for wringing wet fabrics consisting of a frame with an apertured wringer member of resilient material mounted therein, the aperture of said wringer member being substantially closed by prongs produced by cuts emanating from the centre of the aperture of the wringer member towards the periphery and of the length ,of the radius of said aperture, auxiliary spring means for augmenting the pressure of said wringer member upon the article to be wrung out, said auxiliary spring means comprising a, spiral spring arranged about said aperture, and

means for supporting the frame.
