used for wringer mops and which may be detach ably held on a mop handle by means of a sleeve slidably and rotatably mounted on the handle and suitable fastening means for t 1e mop head at one end of the handle.

The present invention has for one of its objects the improvement of the mop head to make it more durable than heretofore, while another object of the invention is an improvement in the manner of fastening the mop material more rigidly to the sleeve. It has been a defect of mops of this type that the mop pad which is usually tied to the rotatable sleeve by tie wires became loose thereon and the sleeve rotated within the pad during the twisting operation which prevented the wringing of the pad and made the mop practically useless. This defect is completely eliminated by the present invention.

With these and other objects in view the invention consists in novel methods of con struction and arrangements of parts which will become clearer as the description pro- 0 terial ready to be formed into a mop head.

Fig. 2 is a front elevation of a completed mop head attached to a mop handle.

Fig. 8 is a side elevation of Fig. 2.

Fig. 4 is a rear elevation of the upper part of Fig. 3 in the direction of the arrow at that figure.

Fig. 5 is an enlarged sectional elevation of the upper part of the mop head on line 55 of Fig. 6.

Fig. 6 is an enlarged sectional plan on line 66 of Fig. 5.

Fig. 7 and Fig. 8 illustrate each diagrammatically the manner of winding one of the tie wires around the sleeve 14 so that they cross each other on opposite sides of the sleeve.

Referring to Fig. 2 of the drawing, 10 is a mop handle provided at its lower end with a looped yoke 11 which holds a mop head 12 removably attached thereto by means 1931. Serial No. 544,462.

of a loop or sheath 13 formed by the mop pad, into which one of the yoke bars is inserted, so that the mop pad extends transversely from the mop axis in opposite directions.

The mop handle carries a tubular sleeve 14 which forms a part of the mop head and is slidably and rotatably mounted on said handle. To said sleeve the ends of the mop pad are fastened in an improved manner which is hereinafter described.

The mop pad consists of a plurality of soft cords 15 arranged longitudinally parallel to each other providing a warp. (See Fig. 1.) Both ends of the warp cords 15 are hemmed in transversely by bands 16. Between these ends, spaced distances from each other the warp cords 15 are Woven tightly together by means of the woof threads 17 to form a fairly rigid fabric. These woven portions are arranged in those places Where the mop pad is subject to greatest Wear and particularly where it is attached to yoke 11 and sleeve 14. For attachment to the yoke a wide woven portion 18 is provided midway between the end bands 16 of the pad, the narrower woven portions 19 near the ends strengthen the pad where it is attached to sleeve 14 and surround the lower end thereof. The other woven portions prevent the free mop cords between them from unduly spreading and help to consolidate the mop pad.

To form a mop head the pad shown in Fig. 1 is first doubled upon itself at its center within woven portion 18 and a band 20 is sewed around both faces of the pad near the ends of portion 18, thus forming a sheath 13. The hemmed ends 16 are bent inwardly, placed against opposite sides of sleeve 14 at its lower end, and fastened thereto as here under described.

The lower, cylindrical part of sleeve 14 is provided with two grooves 21 spaced from each other and provided with teeth 22 transverse of the grooves; (See Figs. 5 and 6.) Near the lower end of sleeve 14 and below grooves 21 two apertures 23 extend transversely through sleeve 14 on opposite sides of mop handle 10. Through each of these apertures a tie wire 24 is threaded these wires are wound about the mop pad in opposite directions, as illustrated in Figs. 7 and 8. Each of these wires presses the mop material into the grooves 21 and against the teeth 22 thereof. The ends of each tie wire are twisted together at 25 as shown in Figs. 5 and 6.

By passing the tie wire through a transverse'aperture of the sleeve 14; and'around two grooves the wire will cross itself and rotation of the wire on the sleeve is absolutely prevented in one direction, a short, lost motion is however possible in opposite direction. But by winding two such wires in opposite directions about the sleeve as describedtheir combined crossings prevent not only any rotary movement but also the short lost motion in either direction, of mop material. relative to the tie wires and. sleeve. In addition there- 'to. the teeth within thegro-oves engage the mop material and resist the strongest turning effort exerted during. the wringing operation of the mop head.

:While I have thus described a; preferred fornrof my invention it shall be understood that modifications may be made. in the design and arrangementofparts, or in the construction of details which come within the-scope and spirit of the invention as claimed.

Having thus described my invention, what ."I claim-as new and desire to secure by Letters Patent is:
