vclaims. (c1. eis-254) Iny the operation of v'clothes wringers, the wringer` is very frequently reversed with relation to the side from which the clothesare fed. When this is done it is desirable to reverse the means for deflecting the water expressed by the Wringer back into the receptacle from which the clothes are fed. The present invention is designed to accomplishthis purpose automatically as the direction of rotation of the wringer -is reversed. The invention is an improvement on the structure disclosed in my Patent No. 1,955,190.

In Athe previous structure a rubber tube engages the undersidevof the lower roll and frictionally engages that roll. 'I'his tube is mounted on a tilting drip board and the drip board is reversed through the frictional engagement of the tube with the roll. Where the surfaces 'of the tube engaged by the roll vare made constant there is a tendency for the friction of the roll to heat the tube. I'his involves an excess of friction and tends to deteriorate the rubber surface of the rubber tube. The present invention is designed to obviate this difficulty. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows:

Fig. l shows a front elevation of a wringer partly in section embodying the invention.

Fig. 9 a section on the line 9-9 in Fig. 6.

Fig. 10 a similar section showing a modification of structure.

In the structure illustrated in Figs. 1 to 4, I marks a base of the wringer frame, 2 the stiles of the Wringer frame. construction and, as shown, the stiles are of box like form in cross section.

Wringer rolls

3 and 4 are provided with shafts 5 and 6 respectively. The shaft 5 of the lower roll is journaled in bearings 1, these bearings resting on bases 8 in the stile. The shafts 6 are journaled in bearings These are of ordinary r 9 slidingly mounted ini the Stiles. 'A' spring VIl) rests on4 thev bearings'l 9 andA is adjustable by screw Il ina top" bar I2'. A resetting' device I3 is adapted to resetfthe topA bar in position and to be tripped by trip bar. I 3a.A This resetting and tripping mechanism areof well known construction and may be of any desired construction.

AAwater board .M is secured by screwsfl .on the base l. This water board has uprightilanges I6 at each endV and an drip board I l likewise having flanges V|8is p'ivotallyy mountedv on the Water board by means of pivot pins I9 .extending through the flanges. r i

A rubber tube 20 is mounted in vaslot '2| between return ends 22 and abase 23 of a tube support. The tube support has an'opening. between the ends 2-2 sufcient to permit Vthe assembly of the tube into the slot 2|. The wall of the tubewhieh extends through the slot is slidingly mounted in the slot, and theupper por-.

tion of the tube engages-the periphery of the lower roll.

The frictional engagement during the ordinary running of the wringer is not very great and tends to hold the drip board in the position toward the side from which the clothes are fed. When the wringer is reversed the friction is sufficient to reverse the drip board, the tube yielding to permit its passage under the lower roll.

The frictional engagement of the rubber tube on the lower roll tends to heat the tube and this heating wears the tube and causes a deterioration. In the present invention when the tube getswarm there is enough pull on the tube to eiect a rotative movement of the tube through the slot 2|, thus providing a fresh surface of the tube to the wringer. Not only this, but this creeping possibility of the tube increases the life of the tube in that it distributes the Wear throughout the whole periphery of the tube.

In the modification shown in Figs. 5 to 9, the Wringer parts are the same except that the base la is of trough shape having a discharge opening 25 surrounded by ilange 25a. The drip board Ila has ilanges I8a. These flanges extend to each side of the anged opening 25. A pivot rod 26 extends across the opening through the llange 25a and through the flanges I8a, thus forming a pivotal support for the drip board below the opening.

A support 21, preferably U-shaped, has openings 28 in each arm through which the rod 26 extends forming a pivot for the support. The lower end of the arms have lingers or projections 29 Which extend into a groove 30 in the bottom of the drip board, thus locking the drip board and the support together. Fingers 3| are struck out of the upper portion of the support forming a slot 32 between these fingers and the wall of the support. A space or opening 33 is provided between the ends of the fingers 3l by means of which a tube 20, similar to the tube illustrated in Fig. 1, may be assembled. The tube 2D operates on this support as in the preceding structures, engaging the lower roll of the wringer and effecting the reverse of the drip board below the opening when the roll is reversed.

In Fig. 10 there is a 'slight modication in that the U-shaped support 34 is provided with a cross pin 35 forming a slot 36 for the receptionof the tube. The return ends of the arms of the support 34 extend through openings 31 in the bottom of the drip board, theends of thearmsf having projections extending into the openings and locking the support with the drip board.

` What I claim as new is:

1.-In a wringer having a wringer frame; a roll mountedin the frame; and `a Awater defiecting drip board pivotally mounted below the roll; the combination withthe roll and drip board of a reversing. device comprising a slotted support connected with the drip board; and a resilient tube having :its'wall slidinglymounted in ythe slot, said tube engaging the roll.

2. In a wringer having a wringer frame; a roll mounted in the Trame; and a water deecting drip board pivotally mounted below the roll; the combination with the roll anddripboard of a reversing device comprising a slotted support oonnected with the drip board; and a resilient rubber'tube having its wall slidingly mounted in the slot, said tube engaging the roll.

3. VIn a wringer having a wringer frame;.a roll mounted in the frame; and a water deecting drip vboard pivotally mounted below the roll; :the combination with the `roll and board of a reversing device comprising a slotted support on the drip board; and a resilient rubber tube having its wall slidingly mounted in the slot, said tube engaging the roll, one wall of the support being partly open to admit the assembly of the tube.

4. In a wringer having a wringer frame; a roll mounted in the frame; and a water deecting drip board pivotally mounted below the roll; the combination with the roll and board of a reversing device comprising a slotted support on the board, said slotted support being formed of wire having a base resting on the water deiiecting board and return bends extending over the base of the support, the ends of the return bends being separated; and

a Vrubber tube having its wall slidingly mounted in the slot, said tube engaging the roll, the opening between the'return ends permitting the assembly of the tube in the slot.

5. Ina wringer having a wringer frame with a trough at the base, and the trough having a discharge opening `through the bottom thereof; a'roll mounted in the frame; and a water deflecting board pivotally supported below the opening; the combination with the roll and board and the trough with its opening of a rigid support connected with the board and extending through the opening; and a rubber tube on the support engaging the roll.

6. In a wringer having a wringer frame-with a trough at the base, andthe trough having a discharge openingthrough the bottom thereof; and a roll mounted in the frame; the combination with the roll and trough with its opening of a rod extending across the opening; a water deecting board pivotally mounted on the rod; .a support pivotally `mounted on the rod and connected with the boardv and extending through the opening; and a rubber tube mounted Von the sup- 4o portand engaging the-roll.
