4 Claims.

This invention relates to clothes wringers and able drain board.

It has long been the practice to manufacture 'cloth'es wringers in which the rolls were capable of being rotated in either direction. Such clothes wringers have also included a pivotally mounted drain board of such proportions as to extend a substantial distance from opposite sides of the wringer and be tiltable to direct the water removed from clothes into a receptacle for re-use or into a suitable drain. Commonly, it is desired that water, squeezed from clothes, be drained from the wringer on the same side from which the clothes are fed to the rolls. To facilitate use in this manner, as well as to prevent misdirection of water squeezed from the clothes, wringers have more recently been equipped with mechanism by which to automatically tilt a drain board in the above mentioned desired direction. Such mechanism, as has been developed and put into use, is' operated through contact with one of the wringer rolls. By reason of this contact, considerable wear occurs both in the mechanism and the rolls, rendering the mechanism subject to breakdown and materially decreasing the efliciency of the rolls as a clothes wringing medium.

It is an object and purpose of the present invention to provide an automatic tilting mechanism for the drain board of a clothes wringer,

the mechanism functioning to tilt the board to efiect drainage from the rolls to the side of the wringer from which clothes are fed to the rolls.

It is another object of the invention to provide a drain board tilting mechanism that is operated by rotation of the clothes wringer rolls.

Another and most important object of the invention is the provision of drive means for tilting a drain board that, although operated by rotation of the wringer rolls, does not cause the rolls to become misaligned, worn, or otherwise in any way rendered ineffective for their intended purpose.

It is additionally an object of the invention to provide a drain board tilting mechanism, driven by rotation of the wringer rolls, that employs anti-friction means for its power take-off from the rolls.

Other objects and advantages of the invention will be more fully understood from a consideration of the following specification, taken in conjunction with the accompanying drawing; and in which:

Fig. 1 is a fragmentary front elevational view of a wringer in which is embodied a tiltable drain 2 board and operating mechanism therefor, parts of the wringer enclosure being broken away to disclose the general location and arrangement of board and mechanism;

Fig. 2 is an enlarged fragmentary view, partly in section, of the drain board and operating mechanism shown in Fig. 1;

Fig. 3 is a fragmentary vertical sectional view taken substantially on the line 3-3 of Fig. 2 and shows the drain board in the tilted position it must occupy when the lowermost roll rotates in a clockwise direction as viewed in the drawing; and

Fig. 4 is a view similar to Fig. 3 showing the other tilted position the drain board must occupy when the adjacent wringer roll rotates in a counter-clockwise direction.

Referring more particularly to the drawing, the reference numeral Ill is employed to generally designate a wringer in which is embodied one form of the invention. Although the invention is applicable to many types of wringers, the present wringer is shown to comprise uprights or end posts II, top I2, conventional roll pressure adjusting knob l3, and rolls l4 and It. The wringer illustrated includes aprons I! that assist in guiding the clothes to be wrung out to and from the rolls I4 and I6. Heretofore it has been the general practice to provide a drain board of a width substantially the length of the wringer rolls. However, in the present wringer, a closed base [8 is providedycentrally of which is located a drain opening [9. This opening is small and thus only a comparatively narrow drain board is required to direct the flow of water during operation of the wringer. It will be noted that the edge of the opening I9 is rolled downwardly to provide a rim 2 I. Adjacent opposite sides of this rim the base l8 may be formed with bosses 22 having downwardly opening threaded apertures adapted to receive screws 23.

A bracket 24 is adapted to be attached by screws 23 to the lugs of the base l8 along identical flanges 26. As may be seen in the drawing, the bracket 24 from the securing flanges 26 comprises identical pairs of flanges 2i and 28, each pair clined base 34, includes sides 36 which, midway of their length, are of such proportions as to constitute satisfactory attaching flanges. A shaft 31 projects through suitable concentric openings in the sides 36 and flanges 21 and 28 of the bracket 24. Any suitable means may be provided to prevent displacement of the shaft. Between the spaced apart flanges 28 of the bracket there is located a U-shaped tiltin member 38. The base wall 39 of this member is secured to the drain board, preferably along the base wall 34, substantially as illustrated in the drawing. The sides 48 of the member are parallel to and lie in close proximity with the flanges 28, and terminate at their free ends in open-ended slots 4|. It is to be observed that the shaft 31 passes through the sides 40 and thus any movement of the free ends of the tilting member 38 causes it and the attached drain board 33 to pivot about shaft 31.

Between the sides 4|] of the tilting member 38 there is located a roller 42. This roller is mounted on a shaft 43, the ends of which are supported in the slots 3| of the bracket flanges 28. The ends of the shaft 43, in order to be mounted in slots 3!, must, as shown, enter the open-ended slots 4! of the sides of the tilting member 38. The roller 42 is formed from suitable resilient material and is adapted to have pressure contact with wringer roll M to an extent as to be freely rotatable with the wringer roll. To further assure obtaining the desired rolling contact between roller 42 and roll hi, the roller may be formed to include a number of resilient, more readily compressible rollin areas 44, substantially as shown in the drawing.

To more fully understand the advantages of a the structure described, its operation may be briefly set out as follows:

Referring particularly to Fig. 3, it is assumed an operator desires to feed clothes into the wringer from the direction indicated by the arrow A and that under such circumstances the lower roll M will travel in the direction indicated by the arrow B. Immediately on the start of rotation of the roll l4, roller 42 will rotate and be bodily moved to the extent permitted by the travel of shaft 43 in slots 3!. Movement of the roller 42 into this position (Fig. 3) has caused the shaft 43, by reason of its engagement with arms 40, to swing the member 38 and tilt the drain board 33 into the position shown. Should it be desired to feed clothes into the opposite side of the wringer, that is, from the direction indicated by the arrow C of Fig. 4, the direction of rotation of the wringer rolls is reversed and roll It now rotates in the direction indi- '1 cated by the arrow D. Such rotation of roll l4 causes roll 42 to move shaft 43 to the opposite ends of slots 3!. As such travel of the shaft 43 takes place, the tilting member pivots to tilt the drain board into the position shown in Fig. 4.

It will be apparent from the foregoing that this mechanism not only tilts a drain board to the desired angle for drainage but maintains the drain board in its tilted position with a minimum of friction and wear of the operating parts, and that the mechanism functions, substantially instantaneously upon reversing the direction of rotation of the wringer rolls, to tilt the drain board and positively hold it in its newly tilted position and, although applicants tilt to hold a drain board to one position or another, it will be understood that variations in the details of this structure may be made and are contemplated insofar as they are within the spirit and scope of the invention as set out in the annexed claims.

Having thus set forth our invention, What we claim as new and for which we desire protection by Letters Patent is:

1. In a wringer structure having a frame, a pair of cooperating rolls mounted in said frame, a pivotal drain board located beneath said rolls, a roller, means having a stationary slot for mounting said roller for rolling contact with one of said rolls and providing for limited bodily movement of said roller in a direction perpendicular to said rollers axis of rotation, and means carried by said drain board and actuated by bodily movement of said roller to tilt said board.
