1 Application niea Ju1y26,

My invention relates to mop'sand more particularly to reversible mop heads. V

It is. a purpose of my invention to provide" a mop head of the above mentioned character fi that comprise-s a frame member'that is pref-- erably made principally of wire and that is so constructed that the same may be moved into a plurality of different angular positions relative to the handle of the mop' and will remain in. adjusted angular position. v More particularly my invention comprises a wedge shaped frame'member ofwire, a clip member adapted to be mounted on the handle member.

and means for connectingthe frame with the" clipmember so that the-frame may be moved, into any desired position-relative to send clipand remain in adjusted position.

The frame memberis preferably;made of spring ,wire' and comprises end portions that 29 extend inwardly toward thecentral portion of the frame toward each other, saidend por-v tions being provided with laterallybent ends. The inwardly extending ends of the wire frame aremountedjina clip carriedby the handle member so as'to bepivoted on their longitudinalaxes, extending through suitable ears in the clip'for this purpose. Itis a par-. ticular purpose of myinventionto so con-' struct theclip that the same will-cooperate 30 with the laterally bent ends of the wire frame to hold the frame in any desired adjusted positionabout' the pivotal axis thereof rela tive to the clip. This is accomplished byprovidingsp'aced tubular ears on the clip bee tween which the bent ends of the wire frame are located and to so form the .edgesof the ears adjacent the said ends that-the same will act on the bent ends of the frame toexert a tension on the spring wire of the frame as. the clip and frame are rotated relatively; to each other to thereby create a frictionbetween said bent ends andthe clipthat is sufficient to hold the frame inany desired position relative to the clip. Preferably the end'edges of the tubular ears are bevelledofi to. form cam portions to accomplish-this.

. It is a further purpose of my invention to provide a mop head of the above mentioned character that, is so constructed thatthe' mop swab can ;be readily put in position on the of the swab and showing "the mop. headcon- V Fig. at

Referring in detail, to the drawings, the mop) head comprises a'fraine 5, preferably made of spring wire andbentsubstantially j at the center thereof to provide 'a' forwardly f U extending' rounded-toe portion 6, the "frame member ;further comprises side portions 7 that extend from the toeportions 6 in diverging relation towardthe rear endtportion of the frame and from such sideportions the 1 rear end portions 8 extend inwardly'towa'rd each other in spaced relation. The wire forming the.;frame is bent in anflobliquely extending 1 direction outwardly toward the side members of the frame as indicated at 9 from the portions 8, and is provided with portions 10 that extend substantially parallel to the side portions 7 and are secured thereto in any suitable manner, as by means of spot welding. Thus a pair of elongated loop-like heel portions are provided at the rear end of the frame member 5 and the frame is stiffened adjacent said loop portions. From the portions 10 of the frame, the end portions 11 extend inwardly toward each other and lie on substantially the same axis, terminating in the laterally bent end portions 12.

A clip 13 is provided for securing the frame 5 to the handlel l. The clip 13 is preferably made of sheet metal doubled on itselfto form the spaced tubularear portions 15, the material of the clip being cut away to provi'de a space or opening 16 between the tubular ears15, said tubular ears being located at the outwardly diverging leg portions 17". Said clip is further provided with an out- 7 struck rib portion 18 running lengthwise therewith.

thereof, and a transversely extending outstruck ribportion 19, forming channels within which the securing wires 20 having the inwardly bent end portions 21 are mounted, the two arms of the clip being secured together by-spotwelding or in any other desired mannerto hold the wires 20 in the channels provided in the clip for the same.

The opposite ends of the wires 20 extend in grooves 22 provided in the handle member 14: and have inwardly. directed end portions 23 mounted in recesses 24 provided in the handle 14 and intersecting the grooves 22, said members 20 being held in position in the grooves 22 and recesses 24 by means of the sleeve 25 secured to the handle 14 in anv desired manner.

The tubular ear portions 15 receive the end or pivot portions 11 of the frame 5 and have the end faces 26 thereof bevelled in 0pposite directions so that the portions 27 thereof more remote from the handle 14 are spaced at considerably greater distances from each other than the portions 28 thereof nearest the handle. Thewire frame member 5 is made of spring wire and is preferably so shaped that when the bent end portions 12 thereof are in engagement with the portions 27 of the end walls of the cars 15 the frame will be slightly under tension and the bent end portions 12 will be frictionally engaging Upon rotation of the frame 5 about the axis of thepivot portions 11 thereof. the laterally bent end portions 12 will ride along the inclined surfaces 26of the ears 15 and will be drawn inwardly toward each other no matter in what direction the frame is rotated from the position shown in full lines in Figs. 11 and 3,.such a position ofthe bent ends 12 being shown in the dotted lines in Fig. 3. The frictional grip of said laterally bent ends 12 of the frame is thus being increased as the same are rotated away from the full line position shown, and the frame 5 will be held in any desired angular adjusted position relative to the clip 13 and handle 14 due to such frictional engagement of the laterally bent ends 12 with the cam faces 26 formed on the ears 15.

It will be noted that the laterally bent end portions 12 of the frame are spaced from each other to permit the cams to act thereon as described above, and it will further be noted that the spacing of said laterally bent ends is such as to provide a gap of considerable width between the same. This is done so as to permit the insertion of the mop frame 5 into the relatively narrow opening 29 leading into the glove-like pocket portion provided in the swab 30 for receiving the frame. Upon reference to Figs. 1 and 2 it will be seen that the maximum transverse dimension of the frame at the portions 8 thereof, is more than the greatest dimension of the opening 29 transversely of the frame, as shown in Fig. 2. The swa'b 30 can be stretched transversely from the position shown in Fig. 2 to make the dimension transversely of the frame of the narrow opening 29 somewhat greater than that shown in Fig. 2. It will further be noted that the difference between this maximum transverse dimension of the mop swab opening 29, and the maximum transverse dimension of the frame, when the frame is in normal position, is less than the space between theends 12 oft-he frame when said frame is in normal position. The spacing of the laterally bentends 12 permits the rear portions of the frame "to be contracted until-the laterally bent ends '12 engage with each other, the major portion of the bending taking place in the relatively flexible forward end portion of the frame. The swab of the mop may be removed in 'a similar manner by contracting the mop frame.

It will be seenfrom the above that a mop head is providedthat will permit the adj ustment of the mop to any desired position relative to the handle and will permit reversal of the mop on the handle. It will also be notedthat themop'head is so constructed that the mop swab can be easily put in position and removed from the mop frame.

Having thus described my invention what Idesire toclaim and secure by United States Letters Patent is 1. In a mop head, a't-apered resilient wire frame havinga narrow end and a wide end. said frame having an opening in the-wide end thereof providing normally spaced frame portions at opposite sides of said opening, the

wire forming said frame terminating in normally-spaced end portions inside said opening, and a clip for mounting the frame on a handle having spaced means thereon for pivotally and slidably mounting the spaced ends means of said wire on said clip in normally spaced relation so that said ends are free to move toward each other whereby said frame may be transversely contracted by moving the spaced portions thereof on opposite'sides ofsaid opening toward each'other to assemble a mop swab therewith, said handle being swingable through said opening to reverse said mop.

2. In a device of the character described, aresilient wire frame tapering lengthwise thereof andhaving an opening in the wide end thereof to permit transverse contraction of the wide end thereof and a mounting for together to materially reduce the transverse dimension of said frame on the wide end thereoff 3. In a device of the character described, a soring wire frame having an open side and having inwardly extending aligning normally spaced endportions terminating in laterally bent end members, and a clip having means for attaching the same to a handle member and having spaced tubular bearings thereon in axial alignment, said bearings being much shorter than said inwardly extending end portions of said frame and pivotallyreceiving the end portions of said frame with the laterally extending bent end members mounted between said bearings in normally spaced relation and movable toward each other to transversely contract said frame, said frame being under tension after being assembled with said clip, and said bearings having faces on the adjacent ends thereof with which said laterally bent end members yieldingly engage.

4. In a mop head, a transversely contract-ible resilient frame having an open side pro-' viding spaced frame portions adapted for movement toward each other to decrease the maximum transverse dimension of said frame upon contraction thereof, said frame having inwardly extending end portions normally spaced from each other, and a clip having means thereon for attaching the same to a handle, said clip having spaced bearing.

members thereon pivotally receiving the inwardly extending end portions of said frame, and being cut away to' provide a space between said bearing members, said end portions having laterally extending means thereon and sa1d frame being transversely tensioned upon assembly with .said clio,

whereby said laterally extending means are yieldingly held in engagement with said spaced-bearing members by the tension of said" frame, said end portions lying: in said space between saidbearingmembers and be ing normally spaced fromeach other when assembled with said clip and movable toward each other to transversely contractsaid frame.
