@jaar Hlaefyn/ m www Patented Feb. 20, 1934 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to improvements in mops of that general character particularly adapted for use in cleaning floors.

One of the objects of the present invention is 3 to provide a simple and practical mop having relatively few parts which may be inexpensively manufactured and assembled.

A further object is to provide an improved mop which will be extremely strong and durable in i9 construction and not likely to get out of order due to failure or breakage of certain parts or connections.

A further object is to provide a mop of the first above mentioned character with an improved l head, in which the strands are securely held and locked in position by the means forming a part of the connection with the mop handle.

Other objects will be in part obvious from the annexed drawing and in part hereinafter indi- -fl) cated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the various features of construction, combination of parts and in the unique relation of the members and ,I3 in the relative proportioning and disposition thereof, all as more completely outlined herein.

To enable others skilled in the art to fully comprehend the underlying features thereof that they may embody the same by the "numerous modifications in structure and relation contemplated by this invention, a drawing depicting a preferred form of the invention has been annexed as part of this disclosure, and in such drawing like characters of reference denote corresponding parts throughout all of the views, in Which- Fig. l is a perspective View showing the completely assembled mop ready for use;

Fig. 2 is a perspective view of one of the clampfl ing members;

Fig. 3 is a longitudinal sectional View of the mop and securing means taken substantially along the line 3-3 of Fig. 1;

Fig. 4 is a detail view of the strand clamping member; and

Fig. 5 is a similar view showing a modification of the element illustrated in Fig. 4.

Referring now to the drawing in detail and more particularly to Fig. 1, 10 indicates a mop handle which is usually a cylindrical piece of Wood of any desired length. Near one end of this handle is bored a through opening adapted to receive a threaded bolt 11 having a securing head l2 at one side and engaged by a wing nut 13 at its threaded end. This bolt is adapted t0 adapted to engage and partially embrace a rela- 05 tively heavy wire 18 securing the strands 20 of the mop head.

This wire 18 as shown in Fig. 4 is of generally elliptical shape before being applied to the mop;

the adjacent ends are welded in any desired man- 7.

ner as indicated spot-welded at 19 to form an endless band. The mop strands are folded back upon themselves as shown clearly in Fig. 1 and then the folded parts are inserted through the wire, after which the strands with the surroundu f ing wire are placed in a powerful press to cause the opposite sides 21 o f the surrounding wire rmly and positively grip the folded parts of the strands and positively prevent their removal. It will also be noted that the fold of the strands 80.. 20 have enclosed therein an endless cord 22 as shown in Fig. 1, which provides a supporting means for the mop when the head is removed from the clamp whereby it may dry more readily.

Heretofore in mop constructions of this general type, it has been customary to secure the clamping members 14 permanently to the handle 10 by means of nails or the like and the bolt 11 did not pass through the handle. This has resulted in a frail and unsubstantial construction which frequently broke under hard usage. With the present construction a single fastening means, that is the bolt 11, is used for securing the mop head clamps to the handle and at the same time holds the securing means firmly in place. Likewise, the wire 18 forms a single complementary securing member and also provides a positive means for preventing loosening of the strands. Such an arrangement is vastly superior to those types of mop head in which the strands are held in place by canvas strips to which the strands are supposed to be stitched.

In Fig. 5 there is shown a slight modification of the securing band, that is, the inner surface of the surrounding wire 18 may be slightly corrul05j gated or serrated as at 23 to more rmly nip and hold the strands against relative movement.

The operation and method of using the mop is of course obvious. Attention, however, is di-` rected primarily to the simplicity of the construcexperimentation has shown that the parts willv last until several mop heads have been worn out.

By providing an attaching means as herein shown which may be made or treated to prevent rusting, the mop head is easily removed and may be hung up to dry, which heretofore has been extremelydiiicult, especially where the mop head included several folds of enclosing fabric. Thus it is seen that the invention is well adapted to accomplish, among others, all ofl the .objects andzadvantages herein'set forth.

Without further analysis 'the foregoing will so fully, reveal the gist of this invention that others can byapplying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the Vpriorxart, fairly constitute essential characteristics of the'generic or specific aspects of this inventionand therefore such adaptations should sof and are intended to be comprehended within the meaning and range of equivalency of the following claims.

I claim:

l. A mop of the character described comprising a handle and a mop head, means for securing one to the other, said mop head comprising a plurality of strands bent back upon themselves to Vforrri `a fold, a binding'wire surrounding said strands at the fold and pressed at thereon under great pressure and adapted to be clamped by said securing means, and a loose holding cord passingthrough the folds of the strands.

2. A mop of the character described comprising a handle and a mop head, means for securing one tothe othercomprising a pair of semi-cylindrical clamping members having holes and a bolt passing through'said holes and the end of the handle for forcing said members towards each other, each of said members having a transverse groove at its end adapted to-embrace a'binding wire on'the mop head, said bindinggwire having.;

a roughened surface for engaging the folds of a`
