T. DOMOTC WAS H WRINGER Filed June 29. 1921 27 ik 29 j?" 29---? 2 -f @ha gf BM; A hlmllllllllllllllllllllllllllmllilllllllllHIIIIIXIIIHIllllllllllllllllllmllllfllllllllllIIIlIIIilllmllllllmmllflllllllllllllllllllllllllllllIlllllllllllllllllllllll IllllllIILll block of resilient material is interposed between the beam 23A and the bar 26, as ndicated at 30. rlhis block cooperates with the other resilient members in supplying a yield-` .able pressure to the upper roll 20.

\of substantially smooth hard rubber, as indicated at 34. The outer layer of rubber will, ofcourse, be. somewhat pliable, as in the case of the present wringer rolls with the backing of sponge rubber it will be possible for the rollers to adapt themselves to minute irregularities and inequalities in the thicknesses of the articles passed .between the rolls in slich a way as to thoroughly exclude the water therefrom and to prevent the Water from passing between the rolls with the goods.

. In order that the wringer may be used from either side of a tub, or to run clothes into or out of a tub, a reversible guide board 35 is provided. This guide board is fitted with trunnions 36 at its ends, which trun-v nions are supported by spring clips 37. One pair of these spring clips is mounted upon the opposite faces of the uprights 11 and 12, thus making it possible to instantly remove the drain board from one side of the wringer and install it upon the opposite side.

The means for clamping the wringer to a tub or other support consists of lates 38 which are screwed to the faces o the uprights 11 and 12. These plates are formed integral with arms 39 extending outwardly and downwardly. The ends of these arms are formed with threaded bosses 40 through which clamping screws 41 are fitted. The outer ends of these screws are formed with wings Li2 by which they may be rotated, while their inner ends are formed with circular pressure discs i3 over the face of which a pad of rubber 4A- is secured. rlhis rubber pad co-o-perates with a pad of rubber l5 carried by the plates 38.

in operation of the present invention the wringer is mounted upon a desired support and thereafter fixed in position by the clamp screws Lil. These screws, of course.l simultaneously draw the clamping pads 4&5 against one side of the tub, or other support, while the pads all are pressed against the opposite side, thus firmly holding the frame in a desired position. The adjusting screw 28 may then be forced down to create pressure upon the roll 20. 1When the crank i8 is operated the roll 15 will be rotated and. the goods may be forced between the rolls 15 and 20.

A* applied and at the same time conform -to them inname Due to the structure of the rolls, as disclosed in Fig. a, the outer surfaces of the rollers will conform to the sectional contour. of the material passing between the rolls and will force the moisture from the material. At this time, the meeting surfaces of the rolls on each side of the material will be brought together, thus preventin the water from passing around the sides o the goods being fed through the wringer. ln the event that an excessively large piece of goods is fed through the wringer, or that the goods are not properly distributed over the base of the lower roll, the resilient members 25 and the small resilient members 29 will be compressed to permit yielding of the upper roll in addition to the amount of compression produced along the rolls themselves.

The drain board 35 may, of course, be to the side of the wringer from which the Wet material is being fed'. When the balls 25 become distorted, they may be forced along the opening between the bar 26 and the beam 23 until they are properly seated, within corrugations suitable for their accommodation.

llt will thus be seen that the invention here disclosed is decidedly simple in its construction, providing inexpensive and readily replaceable means for producing pressure and a desired resiliency of the wringer, and that the Wringer rolls are so constructed as to insure that a maximum and even extraction of water will be made from the material passed therebetween, and to uniformly dry the clothes and in some instances to uniformly distribute starch therethrough,

While l havel shown the preferred form of my invention, it is to be understood that various changes may be made by those skilled in the art without departing from the spirit of my invention.

Having thus described my invention, what ll claim and desire to secure by Letters Patent is:

1. A wash wringer comprising a frame; a relatively fixed, wringer roll' rotatably supported thereby; a movable wringer roll disposed above said fixed roll; a pressure beam acting against the trunnions of said movable roll; a transversely extending bar parallel to said beam; resilient means inter-- posed between the bar and beam; an ad justable pressure screw carried by the frame 'and acting against the center of sai-d bar to force it downwardly; said pressure beam and parallel bar being formed with recesses ofdifferent sizes along their adacent faces for accommodating the resilient means.

2. A wash wringer comprising a frame; a relatively .fixed roller rotatably supported by said frame; a relatively movable roller rotatably supported by the frame; a pressure beam slidably supported by the frame and extending parallel to the rollers; means one disposed in any pair of recesses at each at the ends thereof for imparting pressure to the trunnions of the movable rollers; a pressure bar slidably supported by the frame and disposed above the beam, said bar and beam having adjacent converging faces extending from their ends and terminating near the centers thereof; a resilient block disposed between the center portions of the adjacent -faces of said bar and beam; pairs of recesses being formed along the converging faces of said members, resilient balls,

end of the beam and bar; a cross beam forming a part of the frame; and an adjusting lo screw carried at the center of said cross beam and adapted to exert pressure uponA the bar.

3. A wash wringer comprising a frame; a relatively fixed roller rotatably supported by said frame; a relatively movable roller rotatably supported by the frame; a pressure beam slidably supported by the lframe and extending parallel to the rollers; means at the ends thereof for imparting pressure to the trunnions of the movable roller; a pressure bar slidably supported by the frame and disposed above the beam, said bar and beam having adjacent converging faces extending from their ends and terminating` near the centers thereof a resilient block disposed between the center portions of the adjacent faces of said bar and beam; pairs of recesses being formed along the converging faces of said members, resilient balls, one disposed in any pair of recesses at each end of the beam and bar; a cross beam forming a part of the frame; an adjusting screw carried at the center of said cross beam and adapted to exert pressure upon the bar; and a plurality of yieldable members interposed between the cross members of the frame and the bar for yieldably maintaining the same in position in. the frame.
