UNITED STATES SIMEON C. LAWLOR, OF CHICAGO, ILLINOIS.

MOP WRINGER.

Application filed March 18, 1919. Serial No. 283,408.

To all whom it may concern:

Be it known that I, SIMnoN C. LAWLOR, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mop Wringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

Thepresent invention relates to wringers for mops and the like particularly adapted for application to tanks and other large containers which may or may not be transportable. The object in view is to provide a wringer which may be operated to quickly advance and retract the movable rollertoward and from-the fixed roller by means which are readily accessible to the user and which require but slight manipulation; and to provide a mounting for the parts of the wringer to house and protect the same and facilitate the rigid mounting thereof on the tank. With these and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combina tions and arrangements of parts as subsequently specified and claimed.

In the accompanying drawings Figure 1 is a side elevation ofa wringer constructed according to the present invention and applied to a portable tank.

' Figure 2 is a top plan view of the same, certain parts being shown in section.

Figure 3 is a vertical transverse section, enlarged, through the wringer as applied to the tank, the section being taken through the movable roller in the position shown at 3-3 in Figure 1.

vFigure 4 is a similar view taken through the fixed roller on the line 4t of Figure 1.

Figure 5 is a side elevation of the upper part of the wringer, showingthe tank partly in section and supporting the wringer. Referring to the drawings by numerals, 10 designates a tank of any suitable type, and shown in the present instance as mount-- ed upon wheels 11 by brackets 12 for facilitating the shifting of the, tank 10 into various places for use. The tank 10 is provided across the topthereof, and intermediate its ends, with a brace 13'shown in the form of dinally of the tank.

a strip of metal bolted or otherwise suitably secured to the sides of the tank 10 for holding the brace 13 crosswise and rigidly relative to the tank.

The frame of the wringer is composed of a pair of side members 1 1 and 15. These side members are of hollow construction, having vertically disposed plates 16 at their inner sides and carrying out-turned flanges along their upper edges, which overhang and are adapted to partly enclose and protect the operating devices hereinafter men tioned. Theside'members 14: and 15 are arranged toward opposite sides of the tank 10 with one side member 14 arranged directly over the adjacent side wall of the tank, and with the other side member 15 extending in spaced relation from the opposite side of the tank from thebrace 13 longitu- The side members 1 1 and 15 extend beyond the adjacentend of the tank and carry intheir ends pulleys or grooved rollers 17 adapted to support a flexible connector 18, such as a chain, formed in two separate lengths, one for each pulley and connected at their lower ends to a treadle 19. The treadle 19 is pivoted, preferably, on a pin 20 located upon the adjacent bracket 12 of the tank, and has a treadle plate 21 extending outwardly from the tank for easy access of the foot of the operator for depressing the treadle operating the connector 18. I

The side members 14 and 15 of the wringer frame carry therebetween a fixed roller 22, the trunnions of which, as shown in Figure 4, have bearing in apertures formed in the side plates 16 near the lower edges of the latter. The roller is thus supported with its axis below the top of the tank 1 and in a position adjacent to one end wall of the tank. The side plates 16 are also provided in ,a horizontal plane disposed above the top of the tank 10 with a pair of longitudinally extending slots or guideways 2 1,015 a width sufiicient to snugly receive through the slots the trunnions or shaft 25 of a movable wringer roller 26. r The shaft 25 at one end projects through and beyond the adjacent side. member 14 and is adapted to carry a hand crank 27, or other suitable device for turning the movable roller 26 when desired.

The opposite ends of the. shaft 25 of the movable wringer roller are provid'ed with slides 28in the form of overlapping and offset plates riveted or otherwise suitably secured together at their overlapping ends and with one plate arranged to sllde fiat against the outer face of the adjacent vertical wall 16 of the respective. side member. The.

other plate of theslide 18 is provided with a suitable hook 29, or the like, for engagement with the adjacent length of the connector 18, the platecarrying the hook 29 havingits projecting end spaced from the adjacent vertical wall 16' to admit the "free swinging of the hook and to accommodate the connector 18; Depression of the treadle 19, throughthe connector 18, draws the movable roller 26 forward toward the fixed roller '22, and suitable means is provided for retracting the movable roller .when thetreadle is released. In Figures 1 to 4 the retractmg. means' shown' compr ses a'lever 30 pivoted intermed ate ltsends upon a p1n31 pro- 'jectingupwardly from the cross brace 13 toward one side of thewringer frame, adj acent the side member 15; and with one end of the lever 30 terminating intermediate the planes of the vertical walls 16. .A 'link" is pivoted to said end of the lever 30 and connectedto said end a clip or attaching plate 33 which is carried upon a transverse rod 34 arranged in spaced relation to and in. rear of the movable wringer roller 26. The endsof the rod 34 are seeuredto the sli'des28 so that the slides with the rod 34 1 and other adjacent parts form a reciprocating carriage within 'which' the movable roller is mounted.

f "The other or outer end of the lever30 pivotally attached to a longitudinally mova-v blebar 35 adapted to slide over the top edge oflthe adjacent side wallet the tank 10, which top edge may be made of anydesirled width and protected byan angle iron 36 projecting inwardly from the side 01 the tank. The, bar 35 carries upon its forward end an upstanding handle 37 of suitable' form and length for grasping by the hand to pull the bar The bar 35 is guided in its longitudinal movement by a strap which is "looped over the top of the bar intermediate .its end and riveted, such as shown in Figure 3, over the outer vertical flange of the angle iron 36: The inner portion of the strap 3,8 extends inwardly and is reentorced by a companion lower strap 3?) likewise extending inwardly, the two straps and and 39 being riveted or otherwise suitably secured to an outstanding lug 40 carried by the adjacent side member 15. The outer-end of the lower strap 39 preterablybears against the under side of the horizontal flange .ofthe angle iron 36 and may be riveted thereto for anchoring and "supporting the side member 15 of the wringer. frame. It is evident that when thelhandle 37 is forwardly will rock the rollers apart.
