6 Claims. c1. 68-264) This invention relates to clothes wringers and particularly to a novel structure of a drain board for domestic washing machine wringers.

When hand crank operated wringers were in common use women operators learned the proper method of feeding clothes to the wringer and were careful to spread the clothes over the face of the rolls and to avoid bunch feeding of the clothes which made the wringer crank hard to turn. However, with the power driven conventional domestic washing machine wringers the effect of bunch feeding was not so clearly demonstrated and bunch feeding of clothes is now a more or less common practice. In fact many operators merely feed some portion or the clothes into the roll and permit the rolls to act as a power elevator to drag the balance of the garment through the wringer.

It is the particular object of this invention to provide a drain board which will act to spread the clothes being inducted through the wringer of a domestic washing machine.

Another object is to provide a drain board for a domestic washing machine wringer which will permit clothes to be inducted through the wringer without being caught or damaged by the drain board.

Now referring to the drawings:

Fig. 1 is a front elevation view of a wringer complete with a pair of my drain boards attached;

Fig. 2 is a plan view of the same wringer shown in Fig. 1;

Fig. 3 is an end elevation View of the same wringer;

Fig. 4 is a front sectional elevation view of the drain board as it would appear on the section lines 4-4 of Fig. 3; and

Fig. 5 is an end sectional elevation view of the drain board as it would appear on the section lines 5-5 of Fig. 4.

I show a pair of my drain boards [6 attached to a conventional wringer having a main frame II], a gear drive head ll, safety pressure release bars l4, and a pressure adjustment screw it. The wringers have a pair of wringer rolls l2 and 13 mounted within the frome It and power driven through gears in the wringer head I I.

This structure is well understood in the art and will not be described in detail any further as the function of those parts are well understood.

It will be noted that my drain board It has an arcuate plan projection from the frame 10. As a matter of fact, in this preferred embodiment of my invention the upwardly projecting rim portion H is formed within the true arc 19, which is practically a semi-circle, and the outer are It. The are I9 encloses the drain basin 20. It will be appreciated that this arcuate projection of my drain board has the effect of spreading clothes as they may be inducted through the rolls i2 and i3 and being dragged over the outward arcuate edge i8. Heretofore drain boards have been made more or less rectangular in shape although proveded on the outward edges with rounded corners. It will be appreciated that such rectangular projecting drain boards afford no structure which would act to spread the clothes as does my arcuate edge l8, and moreover the corners of such rectangular drain boards provide ready opportunity for catching the clothes. It will be appreciated that the arcuate projection of my drain board with the outer edge l8 flowing smoothly into th frame IE1 does not provide any such opportunity for catching clothes. As a matter of fact, this arcuate formation provides means whereby the clothes are spread before they enter the rolls and no opportunity is afforded for the clothes to catch on the drain board.

My drain boards are attached to the main frame It by any conventional method through the vertical inner wall 21 shown in Fig. 5

Having thus described my invention, I claim:

1. In a drain board for a domestic washing machine clothes wringer, an arcuately projecting top edge, said top edge being formed between an arcuate inner edge and an arcuate outer edge tangent at the center of the drain board, a drain basin within said top edge having a drain outlet at the said point of tangency, and an arcuate vertical side Wall adjoining said arcuate outer top edge, said arcuate side wall and top edge providing bow means to spread and distribute clothes as inducted through the wringer.

2.. In a drain board for a domestic washing machine clothes wringer, an arcuately projecting top edge, said top edge being formed between an arcuate inner edge and an arcuate outer edge tangent at the center of the drain board, a drain basin within said top edge having a drain outlet at the said point of tangency, and an arcuate vertical side Wall adjoining said arcuate outer top edge, said arcuate side walls and top edge adjoining the wringer frame with no projections to catch clothes as inducted through the wringer.

3. A drain board having an inclined clothes receiving surface of arcuate formation curved throughout its extent and one edge face of which lies in an inclined plane to the bite of the rolls and is of U-shape, the upper edge of the legs of the U being of substantial width and the remainder of each leg gradually diminishing in width and meeting at the base, thus providing a com- 5 pletely curved inclined edge on which the clothes will ride and be spread outwardly thereby while being drawn thereover by the rolls.

4. In a clothes wringer including a frame and a pair of co-acting pressure rolls, a drain board having a characteristic clothes contacting upper surface; said surface comprising an inner edge, an inclined central panel and a marginal outer edge, the inner edge being located adjacent the wringer rolls at a point substantially midway between the ends of said rolls, below the bite of the rolls, and closely adjacent the surface of the lower roll; said central panel extending angularly downwardly and outwardly from the inner edge to a point remote from and substantially below said inner edge to provide an inclined water shed adapted to carry free drain water away from the rolls; said central panel including side portions curved upwardly at each side of the panel and terminating in the marginal outer edge; said marginal outer edge comprising a clothes receiving surface of arcuate formation curved throughout its extent and forming a U-shape which lies in an inclined plane to the bite of the rolls, the upper portion of the legs of th U being above the plane of the central panel to confine the flow of free drain Water to the central panel, and the lower portion of the U lying in contiguous relation with the outward portion of the central panel, thus providing a curved inclined 3'5 edge on which the clothes will ride and be spread evenly outwardly while being drawn thereover by the rotation of the rolls.

5. In a clothes wringer having a frame andl coacting pressure rolls, a drain board at one side of the rolls for supporting clothes during feeding movement to the rolls, said drain, board having a concave upper surface curved in cross section and sloping downwardly from the rolls substantially to a point at the outer edge of the drain board, and upwardly projecting rim portions on opposite sides of said concave surface and sloping upwardly from the outer edge portion of the drain board, said rim portions, in plan, having arcuate inner edges extending substantially throughout a semi-circle with the closed side thereof at the outer edge of the drain board to which arcuate inner edges the oppostie sides of the concave upper surface slope upwardly and said arcuate edges forming the lateral edges of the concave upper surface, whereby the clothes are spread laterally during inward movement thereof over the concave surface.

6. In a clothes wringer having a frame and coacting pressure rolls, a drain board at one side of the rolls for supporting clothes during feeding movement to the rolls, said drain board having a concave upper surface curved in cross section and sloping downwardly from the rolls substantially to a point at the outer edge of the drain board, and upwardly projecting rim portions on opposite sides of said concave surface and sloping upwardly from the outer edge portion of the drain board, said rim portions, in plan, having arcuate inner edges extending substantially throughout a semi-circle with the closed side thereof at the outer edge of the drain board to which arcuate inner edges the opposite sides of the concave upper surface slope upwardly and said arcuate edges forming the lateral edges of the concave upper surface, and said rim portions having substantially arcuate outer edges converging substantially to the arcuate inner edges adjacent the outer edge of the drain board substantially in wedge shape, whereby the clothes are spread laterally during inward movement thereof to the rolls over the concave surface.
