3 Claims.

My invention relates in general to a mop wringer and more specifically to a small portable wringer which is especially adapted for use in homes or apartments and which is designed to fit on the side of bath tubs, laundry tubs or the like where the conformation of the sides of the tubs are of various shapes.

Many types of wringers have been designed and used but so far as I am aware none has been designed which can be clamped to a bath tub or other types of tubs generally found in homes, apartments, or small shops. While the wringer to be described is especially designed for such use, it, of course, is also adapted for general use in factories or office buildings where it can be attached to the side of any sink. It is well known that the sides of bath tubs and sinks vary in contour, thickness and shape through a considerable range and the overhanging lip on such tubs and sinks make the use of standard wringers practically impossible.

The object of my invention, therefore, is to provide a wringer in which the clamping jaws are adjustable to a greater degree than is usual, so as to permit its attachment over the edge of such tubs or sinks regardless of the thickness or contour of the side thereof. Further objects, such as ease of adjustment, lightness, and efficiency of the wringer, will be apparent from the following description, having reference to the accompanying two sheets of drawings.

Fig. 1 is a side view of the wringer shown attached to the side of a tub.

Fig. 2 is a top view of the wringer shown in Fig. 1.

Fig. 3 is a further view of the stirrup of Fig. 2.

Fig. 4 is a detailed view showing further details of the adjustable arm shown in Figs. 1 and 2.

Fig. 5 is a partial view of a modified form of clamping arrangement which may be used for wringers to be attached to laundry tubs.

Referring now more in detail to the structure of the wringer, it comprises two like formed plates 2 and 3 arranged parallel to each other and with the main components of the wringer mounted thereon. .The two plates are held clamped in spaced relation by a pair of rods 1 and 8 at opposite corners of the plates. threaded studs extending through holes in plates 2 and 3 and held by nuts threaded over the studs on the outside of the plates. At the right end of the plates a wringer roll 4 is journalled in the plates and carries a handle 5 for turning it. Mounted adjacent roll 4 is another roll 6 which is carried by the ends of a U shaped arm 9. This Each rod has' roll 6 is rotatably mounted on a shaft H] which extends through slots in both plates 2 and 3 one of which is shown at II. The ends of shaft I t carry washers i2 and [3 between the ends of arm 9 and plates 2 and 3 so that the roll is easily slidable in slots ll. At M is another shaft extending between plates 2 and 3 and carrying on its outer ends the two pairs of arms l5 and It. Between the lower ends of arms I5 and 16 are heavy washers I1 and H which space arms l5 and i6 apart. At the other ends of arms 15 and It the sidesof arm 9 are mounted pivotally by studs i8 and i8 and bolts so that vertical movementup and down of the part 9 of arm 9 causes roll 6 to be moved forward and back in slot H into and out of wringing relation with the roll 4. At the extending portion 9' of arm 9 is attached a pair of chains i9 and I9 which hang down as shown in Fig. 1 and carry a foot stirrup piece 20, spring mounted on rods 2| and 2! by means of springs 22 and 22' as shown in Fig. 3. The arm 9 may thus be operated by foot or by hand.

The adjustable clamping means comprises a pair of small rollers 23 and 24 mounted on four adjustable brackets 25 and 25' and 26 and 26. Each of the brackets 25 and 25 have a small plate 27 and 21' clamped to the corresponding bracket 25 by bolts and nuts which pass through slots such as 28 in plates 2 and 3 so that each assembly is slidable along slots 28. Each of the plates 27 and 21' have angularly bent parts 21" in which a pair of threaded studs 29 and 3B are rigidly mounted. On opposite sides of plates 2 and 3 are mounted a pair of brackets 3| and 32 each having an opening through which studs 29 and 30 pass and a pair of wing nuts 33 and 34 for adjusting the studs to draw the arms 25 and 25' forward in clamping. The opposing clamping bar or roll 24 is as stated mounted on the ends of the adjustable brackets 26 and 23'. The mounting adjustable arms 26 and 26' is more clearly shown in Fig. 4. Each of these arms has a series of slanting notches 35 in the lower edge which may be hooked over the bolt 36 as shown. The bent bracket 21, riveted at 38, forms a slot in which the arm 26 is slidable. At the rear end of arm 26' is a slot 39 which permits forward and back movement on a studAfl which carries a wing nut M for clamping the arm 26 in any position with one of the notches 35 over the bolt 26.

It will be seen therefore, that the roll 24 is first adjusted in a forward or back position depending upon the contour of the side of the tub to which it is to be fastened and then the wing nuts 33 and 34 are tightened to draw the roll 23 against the inner side of the tub opposite roll 25. to rigidly clamp the wringer in place. The handle or arm 9 is then lifted to draw roller 6 away from roller 4 to permit insertion of a mop between the rollers. The weight of arm 9 causes it to fall to bring roller 6 against the mop fabric and additional pressure may be brought to bear by pressing down with ones foot on the stirrup 20 to squeeze the rollers together against the mop.

It should be further noted that the cut-out parts of plates 2 and 3 and arms 25 and 25' as indicated at A and B (Fig. 1) permit a clamping to a tub having any type of flange. At in Fig. 1

- I have indicated a section of one type of tub side having a curved upper edge as shown. It will be seen that arms 26 and 26 can be moved forward or back to cause this curved top of the tub to be readily accommodated by the curved parts A and B.

Referring now to Fig. I have shown a modified form of clamping means consisting of a pair of opposed clamping jaws 25a and 2612 which may be used in place of the previously described jaws 25 and 25 of the other figure. These modified jaws may be usedwhere it is desired to use the wringer only for use with laundry tubs having thin slanting sides, and where it is not necessary to provide adjustment for such varying contours. Also it should be understood that the brackets 25 and 26' may be adjustably mounted in any desired manner other than that specifically shown, and I contemplate having a series of holes for boltsdfi and 36 into any of which said bolts may be inserted to move the members 25 and 25' forward or back and to allow the clamping jaws or rolls to conform to any shaped wall of a tub.

What I claim is:

1. In a wringer, a pair of parallel L-shaped plates, rods spacing the two plates apart and holding them in spaced relation, a fixed wringer roll rotatably mounted between two ends of the plates, another roll mounted in slots in said plates adjacent the first roll, a lever means for moving the other roll inzits slots to'and from the first roll, a curved cut out part in the inside of the L of each plate conforming to the shape of the flangeon the edge of a bath tub, a pair of opposed clamping jaws one on each side of the cut out portions, said jaws both adjustable toward and away from each other to cause the out out portion to be adjusted relative to the edge of the tub on which the wringer is mounted.

2. In a wringer having wringer rolls adjustable to a mop fabric, mounting means for clamping the wringer on the side of a bath tub or the like, said means comprising a pair of clamping rollers, one roller mounted on a pair of brackets having a series of notches in one edge thereof and pins for engagement with any of the notches of each bracket to adjust the roller to different forward and back positions, the other roller mounted on a pair of brackets each having a projection movable in slots and clamping means for moving the other roller in said slots to clamp the two rollers on opposite sides of a tub.

3. A mop wringer comprising a frame formed by two parallel plates adapted to be secured to a tank, a slot extending horizontally in each plate, a fixed wringer roll journalled at each end in one of the plates adjacent one end of said slots, a movable wringer roll rotatably mounted ona shaft having each end thereof slidable in one of said slots, a U-shaped member having its ends secured to the ends of said shaft, a pair of links each having one end pivotally fastened to one of said plates at the other ends of said slots opposite the bearing of the fixed wringer roll and the other end pivotally fastened to one side of said member, said links and member forming a lever whereby downward movement of the member by an operator causes said links to align with said slots and thereby cause forward movement of said shaft in said slots away from the operator and into engagement with the fixed wringer roll.
