Referring, to the drawings, which illustrate the preferred embodiment of the invention, the numeral Ill designates a channel member formed of sheet metal and comprising complementary configured side walls ll interconnected by a transverse web'portion l2 from which the side walls ll extend in generally converging relation whereby the outer portions thereof are spaced apart a distance substantially less than the width of web portion l2. Within channel I is mounted a portion of a mopping element l3 formed of sponge rubber and so compressed in said channel as to be tightly held and gripped therein. The'portion I 4 of the mopping element which projects from the channel flares outwardly from the mouth of the channel whereby its outer surface is of curved contour, as best shown in Fig. 3. Channel I0 is mounted in a bracket interme-.

-; diate its ends, said bracket comprising two parts which are secured together to clamp the channel. The front part I5 of the bracket consists of a plate portion bearing against the front wall ll of the channel and having an integral bent flange l6 bearing on the web I 2 of the channel from the front to approximately the center of said web. At each end of flange I6 is provided a substantially perpendicularly outwardly bent ear I! which terminates in a rearwardly bent end portion I8 spaced from and substantially parallel to channel web l2. The rear part IQ of the bracket comprises a plate portion which bears against the rear wall I l of the channel and is provided with upwardly projecting ears 2!) against which the rear edges of portions l8 of the front bracket part bear. Bracket parts l1 and are provided with aligned apertures through which a bolt 2| extends, which bolt receives a wing nut 22 for drawing the bracket parts into clamping engagement on channel l0. Integrally formed with bracket part 19 intermediate cars 20 thereof is a rearwardly upwardly inclined configured support 23 for a sleeve 24 which fits around the lower end of an elongated mop handle 25. its lower end to provide a pair of opposed parallel cars 26 projecting forwardly and upwardly therefrom; .and is also configured to provide opposed rearwardly and downwardly projecting ears 2'! interconnected by a bolt 28 or other suitable means by which said ears 2'! may be drawn together to clamp the, sleeve on handle 25.

As seen from the front, a U-shaped rigid frame fits over channel Ill and comprises aback 30 preferably reinforced by angularly bent flanges 3! extending longitudinally thereof, and perpendicularly bent ends 32, each comprising a pair of aligned diverging legs 33. A U-shaped bracket 34 is secured at its back to the center of back 35 of the frame, and the legs 35 of bracket 34 are provided with opposed elongated horizontal slots 36. A pin or rivet 31 extends loosely through slots 36 and is carried by opposed forwardly downwardly extending ears 38 of a substantially U- shaped bell crank or bracket 39. A pair of opposed elongated arms 40 extending downwardly from said bracket 39 at the rear thereof are pivoted by a rivet 4! to ears 26 of sleeve 24. An elongated lever 42 is secured at one end to bracket 39 by rivets 43 and extends rearwardly and upwardly from said bracket in normally spaced and substantially parallel relation to handle 25.

Back 30 of the U-shaped frame is provided with an aperture adjacent each end for the reception of a tubular member 44 having its upper Sleeve 24 is cut away adjacent end closed which is provided with a circumferential flange 45 intermediate its ends adapted to bear on the bottom face of back 30. Into the open lower end of tubular member 44 a second tubular member 46 fits in telescoping relation, the lower closed end of tube 48 preferably seating in a depressed off-set ll in the back l2 of channel ID. A coil spring 48 enclosed within tubes 44, 46 serves to press said tubes apart and thereby hold the frame 30, 32 in raised relation to channel if], as illustrated in Fig. 3.

The lower end of each frame arm 33 is apertured to receive an end of a shaft 58, there being two such shafts parallel to and spaced from channel It! and normally opposite channel sides I Each shaft 5|] mounts a wringing member 5| of cam section. Members 5|, as here illustrated, comprise a small diameter portion 52 of substantially semi-circular extent and concentric of shaft 50, said portions 52 being upwardly positioned when said members are inoperative. The normally lower inward portion 53 of members 5| is of enlarged diameter and substantially a quadrant in extent; and the remainder of each member 5! comprises a substantially triangular portion 54 whose lower face merges with the face of enlarged arcuate portion 53 and is normally substantially horizontally positioned. The wringing members 5| are preferably formed of hard rubber fixed on shaft 55, which shaft is journaled in arms 33 of the frame. Fixedly secured to frame arms 33 adjacent the lower ends thereof are brackets 55 from which outwardly downwardly inclined flange stops 56 project to be engaged by the upper faces of portions 55 of members 5|. Channel ill is preferably cut away or notched at 51 at the sides and back thereof, to accommodate depression of frame 30, 32 relative thereto, the arms 33 at each end of said frame 5 being spaced apart slightly more than the width of said-channel adjacent their lower ends and converging upwardly. The spacing of arms 33 is preferably just suflicient to permit lengthwise withdrawal and insertion of channel l0 relative to the frame.

The device is operated by means of lever d2 which tends to depress frame 3|] upon being swung away from handle 25. Springs 48 resist the depression of frame 39 and serve to hold said frame in horizontal position while being depressed. As frame 30 is depressed relative to channel Iii and sponge E3, the members 5| bear upon sponge portion M at arcuate portion 53 thereof to compress and wring said sponge. This compression of the sponge, combined with continued frame depression, serves to rock members 5| relative to their supporting arms so that the normally aligned bottom faces of portions 54 thereof are inwardly positioned in substantially parallel relation, as illustrated in Fig. 4 when the maximum extent of frame movement by lever 32 permitted by elongated slot 36 is reached. In this position, the portionsv 5 of members 5| project beyond the compressed bottom portion of the sponge, so that the full extent of projecting sponge portion It is compressed to insure complete extraction of water therefrom. Thereafter, upon pivoting of handle 3-2 to normal position, the same frictional engagement of members 55 with the sponge, coupled with the upward movement of the frame 35, serves to rock the members 53 re'versely to their normal or starting position. The stops 5% serve to limit this reverse rocking to the proper extent for positioning said members to insure the frictional rock- 2,2os, 10c

ing upon the succeeding downward movement of frame 30. The springs 48 insure raising and normal positioning of the frame 3|], wringers 5| and associated parts in inoperative position illustrated in Fig. 3 to prevent interference of the wringer assembly With the mopping action.

The mop maybe readily assembled and disassembled. Thus, to disassemble the device, the tubular members may be telescoped against the action of spring &8 sufficiently to release member 46 from its seat 41 andpermit the tubes to be angularly swung to be released from the apertures in frame back 3!]. Thumb nuts 22 can then be loosened to release the channel from its mounting bracket and permitlengthwise withdrawal of channel H] from frame 30. I

The cam shape of the wringer members 5| permits complete wringing of the sponge, even when the sponge has become stretched in use; and at the same time prevents over-running of the sponge by said members with consequent objectionable sponge expansion above .or inwardly of the extended wringers which would retard return of the wringers to inoperative position with possible damage to the sponge or distortion and pinching thereof between the channel and wringer when the latter was forced to normal elevated position. In other words, this cam wringer combines the automatic rocking action of a roll wringer with the efli 'ciency and safety of a compression plate wringer.
