Claims priority, application Great Britain August 30, 1951 8 Claims. (Cl. 68-256) This invention relates to wringers.

An object of the present invention is to provide end mountings for the rollers of a wringer, which resiliently urge the rollers together to provide the wringing pressure and permit the wringer to accommodate different thicknesses of clothes, and which eliminate the use of metal springs and manually operable pressure adjusting controls.

An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings, in which:

Fig. l is a fragmentary interior view of an end mounting according to the invention,

Fig. 2 is a sectional view on the line II-II of Fig. 1,

Fig. 3 is a front view of a wringer incorporating the end mountings, I

Fig. 4 is a front view of the upper portion of the wringer casing, andv Fig. 5 is a sectional view of the wringer casing on the line V-V of Fig. 3.

Referring to the drawings, the wringer (Fig. 3) is pro vided at each end with a mounting A for the rollers 1, and each mounting (Figs. 1 and 2) consists of an elongated pressed metal casing having parallel sides and rounded ends. Each casing has a flat base 2 and a pcripheral wall 3 extending inwards in the direction of the rollers l, and the wall 3 of each casing has an outwardly directed peripheral flange 4 extending substantially parallel to the base 2 of the casing. Within the casing a block 5 of relatively hard rubber is tightly fitted, the block filling the interior of the casing. Two longitudinally interspaced holes are provided in the rubber block 5, and the holes have cylindrical metal or plastic liners or bushes 6 defining sleeved sockets adapted to journal the ends of the spindles 7 of the rollers 1 of the wringer. The distance between the liners 6 is less than the distance between the spindles 7 of the rollers 1 when the latter abut each other, so that when the spindles 7 are fitted at each end into the liners 6, the rollers l are resiliently urged together to provide the required roller pressure, this being predetermined, by the distance between the liners 6 which is less than the distance between the roll spindles when the rolls surfaces 1 are tangent and lightly abut each other. Stated otherwise, the distance between the axes of the liners or bushes 6 is less than the diameter of at least one roll 1, and is less by an amount which will produce the desired pressure between the rollers in accordance with the general nature of the work to be done by the wringer. The pressure between the rollers is efiected by virtue of the portions of the rubber block between the holes and the ends of the casing being held in compression and the portion intermediate the holes being held in tension.

At the lower end of each casing there is provided a downwardly projecting pin 8 which is used in attaching the wringer to a table mounting. The upper end of each pin 8 is secured to a plate 9 which is welded or screwed to the inner surface of the wall 3 (Figs. 1 and 2).

The wringer casing consists of complementary upper and lower portions 10 and 11 adapted to enclose the rollers, while providing the required clothes inlet 12 and outlet 13 and water outlet 14, and the upper portion is also shaped to provide a hand grip opening 15 beaded with suitable beading material 15A. The two portions 10, 11 are shaped to conformto the contour of the flanges 4 of the end mountings A and are provided at their ends with inwardly directed flanges 16, 17 (Fig. 5) which fit over the flanges 4 on the end mountings, the

flanges

4 and 16 hav ing

corresponding holes

18, 18A for small pins, screws or bolts 19 to prevent accidental removal of the upper portion 10 of the casing. The lower portions 11 of the casing is removably held in position by inwardly curved portions 11A at its upper edges which fit over correspondingly curved portions 10A at the lower edges of the upper portion 16, the resilience of the metal permitting the lower portion 11 to be push-fitted into position and to be firmly held in position. Alternatively, the lower portion 11 may also be attached to the flange 16 by pins, screws or bolts.

The drive is eflected by friction between the rollersl and is manually or otherwise operable by a handle (not shown) or other connection to the end of the lower spindle 7 which extends through the base 2 of one of the end mountings A at 7A.

In the embodiment shown, each liner 6 extends from the base 2 of the mounting and projects at its outer end beyond the rubber block 5 so that the ends of the rollers 1 are spaced from the latter, and each liner 6 has a relatively large, peripheral, outwardly directed flange 6A which abuts the face of the rubber block 5 so as to prevent or mitigate outward distortion of the block.

As a result of the invention, the rollers of the wringer are pre-loaded, and the resilient beddings or mountings permit the wringer to accommodate different thicknesses of clothes automatically, the necessity for manual adjustment of the pressure being eliminated. Also, the design of the wringer is greatly improved, and its assembly sim plified, as the number of parts is reduced to a minimum, there being in fact, apart from the rollers and handle, only four main parts, the two end mountings and the two portions of the casing.

I claim:

1. A wringer comprising a pair of abutting rollers, a spindle for each roller, and a pair of end mountings for the rollers, each of said mountings comprising a dished metal casing, a relatively hard rubber block tightly embedded in said casing, and there being a pair of sleeved sockets extending through said block and journalling the ends of the roller spindles, said sleeved sockets being spaced apart a distance less than the distance between the roller spindles when the rollers lightly abut each other, so that in the wringer, the rollers are resiliently urged together.

2. A wringer comprising a pair of abutting rollers, a spindle for each roller, and a pair of end mountings for the rollers, each of said mountings comprising a dished metal casing, a resilient bedding consisting of a block of relatively hard rubber tightly fitted into said casing and having a pair of sockets extending through the block, and a bush in each socket for journalling the ends of the roller spindles, the axes of the bushes being interspaced a distance less than the diameter of a roller so that the rollers are resiliently urged together.

3. A wringer comprising a pair of abutting rollers, a spindle for each roller, a pair of resilient end mountings for the rollers, and a casing interconnecting said end mountings, each of said mountings comprising a dished metal casing, and a block of relatively hard rubber tightly embedded in said casing, there being a pair of sockets extending through the block and a bush in each socket journalling the ends of the roller spindles, the axes of the bushes being interspaced a distance less than the diameter of a roller, whereby the rollers are resiliently urged together throughout their length and are movable apart at any point throughout their length to accommodate different thickness of clothes.

4. For use in a wringer comprising a pair of rollers having spindles; a. pair of end mountings for the rollers eachmounting; comprising a single flat block of relatively hard rubber, the surface of said flat block having two flat opposing faces interposed between a continuous peripheral edge portion, a metal casing tightly enclosing said fiat block about said edge portion and one flat face, and said rubber block having a pair of hushed sockets adapted to journal adjacent ends of the roller spindles, said sockets extending through the block from one flat face to the other and having their axes interspaced adistance less. than the distance between the axes of the roller spindles when the rollers lightly abut each other, whereby each mounting forms a single resilient mounting for both rollers, and, the rollers, when mounted therein, are resiliently urged together.

5. For use in a wringer comprising a pair of rollers having spindles, a pair of end mountings for the rollers, each mounting comprising an elongated metal casing having a fiat base and a peripheral wall, the side portions of the latter being parallel and the end portions being rounded, a flat block of relatively hard rubber of the same contour as the casing and tightly fitted into same, and there being a pair of sockets extending through said a block and having their axes interspaced longitudinally of the block a distance less than the distance between the axes of the rollers when the latter lightly abut each other, and a pair of bushes, one in each socket, for journalling the ends of the roller spindles, so that, when the ends of the roller spindles are journalled in the bushes, the rollers are resiliently urged together at the required operating pressure. a

6. A pair of end mountings as claimed in claim 5, in which each bush has an outwardly directed peripheral flange abutting the face of its rubber block, said flanges preventing or mitigating outward distortion ofthe blocks.

7. A v'vrin'ger comprising a pair of abutting rollers, a spindle extending through each roller, and a pair of end mountings for the rollers, each end mountin comprising a dished metal casing, a block of relatively hard rubber tightly fitted into said casing, and there being a pair of sleeved sockets extending transversely through said block and journalling the adjacent ends of the roller spindles, the axes of said sockets beinginterspaced a distance less than the diameter of a roller so that the rollers are resiliently urged together by virtue of the end portions of the blocks being in compression and the portions inter mediate the sockets being under tension.

8. An end mounting for the rollers of a wringer, said mounting comprising a single block of relatively hard rubber having a pair of sleeve sockets extending transversely therethrough for journalling the adjacent ends of the rollers, and an outer metal casing of the same contour as the block and holding the latter against peripheral distortion, whereby, when the spindles of rollers of greater diameter than the distance between the axes of the sockets are journal'led between two such end mountings, the portions of the block between the sockets and the'ends of the casing are held in compression, and the portion: intermediate the sockets is held in tension, so that the rollers are resiliently urged together to provide an operating pressure.
