7 Claims.

This invention relates to improvements in mops and holders therefor which may be used for a variety of differ'err;V types ci mops and dusters. Y

It is an object oi the present invention 't0 provide a mop holder which permits the mop held thereby to be placed in a plurality `of diiferent positions relative to the handle and'to he rotated about an aXis in each position.

It is a further object of this invention to provide a mop holder which permits the mop toyield in any ci its various positions. It is a further object of this invention to provide a mop holder of soft and resilient material which will not scratch or mar any object with which it may come in Contact during the sweeping operation.

With these and other objects in View the invention consists in certain novel combinations and arrangements of parts hereinafter more clearly described and nally pointed out in the appended claims and illustrated in the accompanying drawings in which- Figure i is a plan view of a door mop provided with my improved holder,

Figure 2 is a side'elevation of my mop holder when attached to a mop and handle.

Figure 6 is a detail plan of the rear part of the plate 30 showing the means for tieing the mop cloth thereto.

Figure 7 is a sectional detail on line 7--7 of Fie'. 5.

Figure 8 is a sectional detail on line 8--8 of Fig. 6.

In the drawings, Fig. l illustrates a heart shaped mop head consisting of a plurality of wire strands 10 which are twisted about each other and hold mop material 11 between them. The wires 10 are bare of mop material in their middle part 10a which is covered by the mop holder and form symmetrical loops on both sides of the handle 12 and a single loop in front thereof. The mop holder consists principally of a single elongated plate 20 shown in Fig. 3 which is preferably made from pure rubber properly vulcanized to be pliable and highly resilient. Plate 20 is provided near its middle portion with two transverse ledges 2l so that between them Serial No. 617,267

(Cl.v 306-41) a deep groove 22 is formed across the center of plate 20. Near the outer sides of each ledge 21 two cylindrical projections 23 are formed on plate 2li which serve as distance pieces. The opposite ends of plate 20 are of semi-circular form and have apertures 24 in their centers. The mop Vhandle i2'is preferably flattened at its end 12a as shown in Fig. 2, and provided lwith an aperture i3 therethrough. To fasten the mop head shown in Fig. l to handle l2 by means oil plate 20 the portion 10a of the twisted wires l0 is placed into groove 22. The plate 20 is then bent into U-shape and the ilat end 12a 'l of the mop handle is inserted between the two circular end portions of plate 20'. In this position the top iaces of each couple of distance pieces 23 and 23d lean against each other and these pieces form a stop for the bottom end ci' mop handle 12 (see Fig. 2). A washer 14 is then placed against each or" the opposite outer faces of plate 2O and a hinge pin 15 pushed through those washers, through the apertures 24 in plate 20 and through aperture 13 in handle end 12a. By means of a wing nut 16 which is threaded upon the end of pin the ends of plate can be drawn against the mop handle 12 and the latter be clamped tightly when it is swung on pin l5 into a desired angle. YThe two ledges 21 as shown in Fig. 2 lean against the wires 10a. When nut 16 is not tightly clamped they and the mop with them may be rotated within the mop holder. But when nut 16 is tightened the ledges 21 clamp wires 10a tightly and the mop is held in fixed position. However the rubber parts of the mop holder permit a yielding oi the mop in any direction which gives the particular advantage that any object, as a piece of furniture when struck by the mop in sweeping, will not be injured by reason of the yielding action. It is of further advantage that the material of the mop holder itself is soft and yielding and will not injure an object which is struck thereby. In Figures 4 to 7, the application of the above described mop holder to an oil mop is illustrated. This oil mop consists of a heart-shaped metallic plate which is surrounded by a gutter 31 at its periphery which is formed by a vertical flange 32 and provided on its outward side with spaced teeth 33. A plurality of smaller apertures 34 are formed through plate 3G at the corner formed by Yllange 32 and gutter 31. The mop swab consists of mop cords which are tied together in their middle portion by weaving them together at 4l and doubling the woven portions over a string or cord 42.

The mop swab and cord 42 are placed against the outside of flange 32 as shown in Fig. 5 and held in position by the teeth 33. The cord 42 is threaded through apertures 35 in flange 32 stretched tightly and bound to holding plate 36 provided on plate 30. In the middle portion of plate 30 an opening 37 is provided which is bridged by a rod 38 to which the niop holder hereinbefore described is attached, the rod 38 taking the place of the wires 10a for this purpose. In Fig. 5 the dottedlines indicate the positions into which the mop handle l2 may be placed relativelyrto the mop by swinging on rod 38. In Fig. 7, the dotted lines indicate the portions into which the mop handle may be placed by swinging it on hinge pin 15. It should be noted that the distance pieces 23 and 23a are pressed out of the way by the corners of the reduced portion 12a when rotating and snap back and press against the bottom of portion 12a as shown and hold the handle in such adjusted position or perpendicular toV rod 38 when not clamped by nut 16.

By these simple means a very eiiicient holder is provided by which mops and other Aarticles may be yieldingly secured to a handle and may be deflected and rotated about the axes perpendicular to each other.

Having thus described the preferred form of my improved mop and holder, it is kto be understood that changes may be made in the arrangement of its parts and the construction of minor details thereof as come within the scope of the invention as claimed, without departing from the spirit of the invention.

I claim:
