for future use.

It is the object of the present invention to provide a mop construction to obviate the aforementioned objections and one that is simple, sturdy, and inexpensive.

According to the above objects, the present invention contemplates a materially simplified mop construction, including a holder having a slightly arcuate portion with contiguous straight side portions extending from the extremities of the arcuate portion. The

arcuate portion is channeled or grooved to a depth greater than the thickness of thestitched portion of the mopping element and its sides are straight and the bottom curved to grip firmly and securely the mop proper and thereby prevent its displacement. s an additional assurance against displacement of the mop proper, projections or protuberances are formed near the ends of the arcuate portion and atthe center thereof over which the mop proper is tightly stretched by means of a stranded cable threaded through the stitched portion of the mopping element. One end of the stranded cable is fastened to a needle-shaped element designed to engage a hook on a sleeve in which a handle is inserted,

while the other end of the cable is secured to an adjustable cam type of clamp which tightens the cable and which is locked against accidental displacement by the engagement of an element integral therewith with the hook also formed on the sleeve diametrically opposite the other hook.

According to a modification, the arcuate and straight portions are each channeled or grooved, but in the case of the arcuate portion 1930. Serial No. 433,640.

the depth of the channelor groove is greater than the thickness of thestitched portion of the mopping element and the sides and bottom of the channel are as previously described.

In addition, the stranded cable is fastened to an adjustable loop end adapted to engage a hook on a sleeve in which the handle is inserted. The other end of the cable is fastened to a cam type of clamp which draws the cable taut due to its cooperationwith another hook of somewhat difi'erent shape and which when freely compressed is locked against accidental displacement.

A better and clearer understanding of the invention may be had from the following de-' scription, taken in connection with the accompanying drawings, wherein Fig. 1 is an elevational view showing the novel and important structure features of the p;

Fig. 2 is a side elevational view of the mop illustrated inFig. 1;

Fig. 3 is a View of the mop showing the stitching;

Fig. 4 is an elevational view of a second embodiment of the invention;

Fig. 5 is a side elevational view of the mop illustrated in Fig. 5;

Fig. 6 is a side elevational view of the mop illustrated in Fig. 5 opposite to that shown in Fig. 6, and

Fig. 7 is a view of one form of mop that may be advantageously used.

Referring now to the drawings in which the same reference characters indicate similar parts in the several figures, the improved mop consists of three. principal parts, a handle 5, a frame 6, and a mopping element 7 all from any suitable or desired kind of material,

but in the preferred form of the invention it is cast, such as by die casting, thereby to reduce its cost of manufacture and elminate machining operations.

As shown in Fig. 1, the frame 6 consists of side portions 8 and 9 which are contiguous with a connecting portion or a section 10. The section 10 is grooved or channeled but the portions 8 and 9 have plain or flat surfaces. The side portions 8 and 9 are straight for the greater part of their length but turn at an abrupt angle near one extremity there of and extend to a sleeve or ferrule integral therewith, which is apertured as shown at 16 to decrease the weight of the frame. The portion or section 10 is curved slightly, and as viewed in Fig. 2, is channeled or grooved at 17, formed by flanges 18 and 19, which flare as shown at 20' and 21, has straight walls 22-22, and an arcuate portion 23, the purpose of which will be more apparent as the description progresses. Located in the groove 17 and transversely thereof at points mediate the other projections.

near the flared portions 20 and 21 are projections or protuberances 24 or 25 with a similar projection 26 formed in the groove 17 inter- These projections extend slightly above the arcuate portions 23 and serve to grip firmly the mop element 7 to be positioned in the groove 17.

The handle 5 is fitted in the sleeve or ferrule 15 on a slighttaper and is rigidly secured thereto by a screw 11 or other suitable type of fastening device. Also in order to insure against turning movement of the handle 5, two sharpened projections 12 and 13 are formed integral with the sleeve or ferrule 15.

which dig into the end of the handle 5 and hold it against rotary movement, while the screw 11 prevents its withdrawal. With such a construction an exceptionally rigid and substantial joinder is made between the handle 5 and the frame or holder 6.

Integral with the sleeve or ferrule 15 are two diametrically oppositely displaced and similarly shaped hooks 27 and 28. The hook 27 which has a curved portion 29 serves as the fastening for a needle-shaped member 30 attached by welding, brazing or otherwise to an end of a stranded cable 31. As shown in Fig. 1 the member 30 has oneend drilled to receive the end of cable 31, while its other end is pointed comparatively sharply for the pur pose to be presently described. The hooks 27 and 28 are so shaped and positioned and the side portions 8 and 9 are so formed with respect to the arcuate section 10 that the cable 31 is out of contact with the sides 8 and 9 for substantially their entire length when held firmly by a latch 32. The latch 32 which is pivotally fastened to the other end of the ca- ;ble 31 through a U-shaped member and a threaded rod 34 which is secured to the cable 31 by welding, brazing or otherwise, cooperates with the'hook 28 to draw the cable 31 tightly in the groove or channel 17 However,

the drawing of the cable taut is facilitated by a cam surface 35 formed on the projecting portion 36 of the latch 32 acting on the surface of the hook 28 such that when the latch 32 is moved by the handle 37 toward the right or in a clockwise direction, as viewed in Fig. 1, a camming action results. The latch 32 is also provided with portions 3838, which. with the handle 37 in the position shown in Figs. 1 and 2, are on opposite sides of the ferrule 15. Also in order to facilitate the securement of the latch 32, two elements 39 and40 are disposed on opposite sides of the projecting portion 36 and integral therewith. Thus these two elements serve to center the portion 36 with respect to hook 28. It will also be noted that the hooks 27 and 28 are so'positioned on the ferrule 15 that the cable 31 with the latch 32 in its locked position will be straight along and out of contact with the side portions 8 and 9, making possible a sufficient tightness of the cable 31 to draw firmly the mop element 7 in the groove 17. In addition, attention is directed to the fact that both hooks 27 and 28 are the same, which makes possible the reversal of the needleshaped member 30 and the latch 32.

The frame or holder previously described may be used in any suitable form of mop element, but the particular type of mop selected for illustration of the invention, consists of a plurality of twisted strands interwoven or stitched at a point intermediate their ends and provided with a tunnel 41 (Fig. 3). The element 30 is threaded through the tunnel 41 and due to its pointed shapeit may be quick- 1y inserted even though the mop has been previously used and cleaned, and has its eye fastened on the hook 27. By inserting the end of portion 36 inside the projecting part of hook 28 and forcing the handle 37 in a clockwise direction and due to the cam 35 and the fact that the length of the cable 31 has been previously adjusted by varying the position of the rod 34, the cable will be drawn tight, resulting in the mop section being firmly engaged by the projections 24, 25 and 26 in the groove or channel 17. Also, since the arcuate portion 23 of the channel 17 is of a diameter only slightly greater than the diameter of the cable 31, the mop section will be firmly engaged by the sides of the portion 2222 and will consequently be very positively secured. It is furthermore noted that the portion or section 10 is substantially equal to the width of the mop and with the projections 24, 25 and 26 positioned as shown, spreading or creeping of the mop is prevented. In addition the cable is pulled along a straight line, thereby additionally insuring that the mop element is securely held in the groove 17 Drainage for the mopping element 7 is also allowed when not in use by providing spaced apertures 42 and 43 in the curved section 10. Also as clearly shown in Fig. 1 the mop is drawn into the apertures 42 and 43, thereby additionally insuring against its longitudinal movement.

In the embodiment shown in Figs. 4, 5, 6 and 7, the handle 5 is secured to a frame or holder designated generally by the numeral 45. The frame or holder 45 is similar in many respects to the holder 6, and those features of similarity are indicated by the same reference characters. As shown in Fig. 4, the holder consists of side portions 46 and 47 which are contiguous with a connecting portion or section 10. Each of these portions are grooved or channeled but to a different degree. 7 In the case of the side portions 46 and 47, the projecting flanges 48 and 49 do not extend outwardly to the same extent as is the case of the flanges 18 and 19. The structural features of the connecting portion or section 10 are the same as described with reference to Fig. 1, except that it is a solid casting and not cut out at 42 and 43 as shown in Fig. 1, and for these reasons a further description thereof is not considered necessary.

Integral with the sleeve 50 are two oppositely disposed and differently shaped hooks 51 and 52. The hook 51 which has a curved portion 53 serves as the fastening for the loop member 54 attached to a threaded element 55 which has a sleeve 56 secured by welding or otherwise to an end of a stranded cable 57. The cable 57 is adapted to be positioned in the grooves formed by the flanges 48 and 49, and 18 and 19, and held firmly by a latch 58. The latch 58, which is pivotally fastened to the other end of the cable 5'? through a U-shaped member 59, which like the sleeve 56 is firmly secured to the cable 57, cooperates with the book 52 to draw the cable tightly in the grooves or channels. The tightening of the cable is also facilitated by a cam surface 60 formed on the projecting portion 61 of the latch 58 acting on a surface of the hook 52. The latch 58 is also provided with portions 38-38 which are on opposite sides of the ferrule when the latch is in its locked portion.

The mop 62 shown in Fig. 7 merely consists of a plurality of twisted strands interwoven or stitched at a point intermediate the ends. The mop is laid over the cable 56 which has the loop member 54 fastened on the hook 51 with the stitched portion in juxtaposition to the cable. The cable is then drawn tight by securing the latch 58 to the hook 52 in the manner already described. Adjustment of the length of the cable can, of course, be obtained by means of the threaded rod 55.

Although the invention has been described as applied to a particular type of apparatus, it is obvious that modifications may be made without departing from the spirit and scope of the present invention as claimed.
