Claims.

In the operation of clothes wringers, the wringer is very frequently reversed with relation to the side from which the clothes are fed. Where 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 accomplish this purpose automatically as the direction of rotation of the wringer is reversed. Features and details of the invention will appear from the specification and claims.

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

Fig. 1 shows an elevation of the wringer, parts being broken away to better show construction.

Fig. 2 a section on the line 2-2 in Fig. 1, with the drip board in the position assumed in normal operation.

Fig. 3 a similar view with the drip board on center, or in a position occupied during the reversal of the board.

Fig. 4 a sectional view showing the connection of the water board and drip board.

1 marks the wringer base and 2 the side stiles, 3 the lower roll, 4 the upper roll, 5 the roll shafts, 6 the shaft bearings which are mounted in the side stiles, '7 the pressure spring and 8 the top These parts are, or may be, of common 0 wringer construction. The water board 9 has a base portion 10 and side flanges 11. It is secured on the base in any convenient manner. It is provided with a bearing opening 12 which is r struck up from the wall of the side flange.

A drip board 13 has side flanges 14 and these side flanges are provided with lugs 15 formed therein which extend into the openings 12 and thus afford a pivotal mounting for the drip board.

At each end of the drip board a rubber ring 16 is mounted on the drip board and secured thereto by a rivet 1'7. The ring 16 is so dimensioned as to engage the lower wringer roll and to maintain contact therewith even with the roll in the operative position shown in Fig. 2. The engagement, or contact, of the ring is so slight as to subject the roll and ring to negligible wear in operation. It will be noted that with the roll operating to feed the clothes toward the left in Fig. 2 that the bottom of the roll will travel toward the right and thus assure through its engagement with the ring 16 the position of the drip board in Fig. 2, which position is the proper position for deflecting the water back into the receptacle from which the clothes are fed.

When the rolls are reversed for a reverse feeding of the clothes the slight engagement of the lower roll with the ring 16 draws the ring into the bite between the drip board and the roll.

The initial resistance of the ring to lateral movement is very slight so that the initial engagement of the roll readily rocks the ring into more definite engagement. As the ring is drawn into the narrow space between the roll and the drip board its engagement with the roll increases, the de pression of the ring permitting it to pass under the roll through this engagement. The effect is a more positive movement, the reversal being made with a snap. The initial movement of the ring is absorbed by the distortion of the ring itself and when the drip board begins to move it not only responds to the movement of the roll, but also to the rolling action of the ring in relieving itself after it gets past the center.

What I claim as new is: H

frame; a roll mounted in the frame; a pivotally mounted drip board; and a reversing device mounted on the drip board and engaging the roll, said device being yieldable perpendicularly and laterally with relation to the board.

2. In a wringer, the combination of a wringer frame; a roll mounted in the frame; a pivotally mounted drip board; and a reversing device formed of rubber connected at its base with the drip board and engaging the roll, said device being yieldable perpendicularly and laterally with relation to the roll.

3. In a wringer, the combination of a wringer frame; a roll mounted in the frame; a pivotally mounted drip board; and a resilient reversing ring mounted on the drip board and engaging the roll, said ring being yieldable transversely.

4. In a wringer, the combination of a wringer frame; a roll mounted in the frame; a pivotally or mounted drip board; and a resilient rubber re-
