This invention relates to a mop stnucture which includes a relatively simple mop handle and base upon which .may be rigidly attached a mop head and same-' adqiustably tensioned there-- on by the housewife and readily detached therefrom when desired The foregoing objective is accomplished by utilizing a loop anchorage with which is associated an adjustable tensioning device of singular or multiple char'acter.

One chief feature of the invention resides [in the coil spring tensioner.

.Ano'ther chief feature of .theinvention resides in the loop anchorage fixed to' the handle and with which is associated singular or multiple means for tensioni ng the loop.

Other objects and features of the invention will beset forth more fully hereinafter.

The full nature of the invention will be-understood from the accompanying drawing and the following description and claims:

In the drawings Fig. 1 is a perspective View of an embodiment of the mop structure including the invention, an intermediate portion of the handle being broken away.

Fig. 2 is a side elevation of that portion of the handle having a fixed anchorage and that portion of the loop associated therewith together with the dual tensioning means.

Fig. 3 is a central transverse sectional view through the base, mop head and adjacent handle portion.

In the drawings indicates a handle which may have a threaded end ll screwed into threaded hole 12 in base [3 and secured by transverse pin [4 if desired. The base is grooved at its outer face as at I5 and may be grooved at the ends as at Hi. The grooves l5 may be inclined outwardly and rearwardly as indicated at H in Fig. 1. The outer corners may be rounded as at 8.

Seatable in the grooving l5-I6 is a loop formed retainer l9 to which is stitched as at the tape 2| that includes the enveloped strings '22, also sewed thereto and forming the mop head.

This mop head is retained upon the base I 3 by tension type forces applied in the inclined portions 23 of the loop. Since the loop herein is shown secured to the tape and strings, it is important that the two portions 23 of the loop be tensioned equally, so that the string portion is centrally positioned relative to base IS.

The handle l0, spaced from the base, mounts an abutment or anchorage 24 in the form of a screw eye upon which the upper end 25 of loop 419-123 isengaged. .is spaced .atrem they-base .a distance ju-st su fiicient for portion .25-.-of,;the

This may v be m ntsfor a -moun in 1 Another tensioni g; device comprises wound springhaving one -.erusl. 3i land .aaflnger n p s l a 152 beior kfl a are-- iflh is utilized as follows: The head is base mounted and portion 25 of the loop is passed over the eye 24, while the spring 30 is on the handle above the eye or opposite therefrom relative to base I3. Then the spring is slid down the handle till the first turn engages eye 24, whereupon the spring is rotated on the handle to screw, as it were, upon the eye. This causes the first turn of spring 30 adjacent finger piece 32 to draw the loop toward the handle I0 upon both sides thereof and near eye 24. As this screwing action is continued more and more of the loop is thus positioned to lie alongside the handle to a lesser or greater extent. This obviously applies increasing tension to loop portions 23.

Removal of the mop head is effected in the first instance by tilting the cam lock from the full line to dotted line positions and in the second instance by reversely screwing the spring. The other operations described in reverse order are effected to detach the head.

As shown herein both tensicning devices are illustrated and in this instance the tiltable cam tensioner is first applied and then the rotatable cam (spring 30) is screwed down, but in this in l stance over the tiltable cam tensioner with which it does not interfere.

Since the loop is of fabric material it will gradually stretch (although to a limited degree) in use, that is when wet and stretched repeatedly incident to attachment and detachment for cleansing and use. The cam tensioner obviously has limited tensioning capacity and is first exhausted. Thereafter progressive tensioning, if necessary, is obtained by use of the screw tensioner, it being understood that the number 01 turns in the springs is sufficient for the purpose described.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein as well as others which will readily suggest themselves topersonsls'killed in this art, all are consldered to'be'within the broad scope of the invention, reference being had to the appended claims.

The invention claimed is:

1. In a mop, an elongated base, a handle con-, nected to and projecting beyond one side of said base intermediate the ends thereof, a mop head for engagement with said base on the opposite side thereof and extending to the ends of said base, a flexible loop member secured at its ends to the ends of said mop-head, an abutment on said handle spaced from said base, the intermediate portion of said loop member engaged over said abutment, a helical member encircling and loosely fitting over said 'handle,'the coilsof said helical member threading upon said abutment, said helical member when rotated in one direction being handle, a mop head detachable with respect to,

disposable upon and substantially coextensive with the base and extending along the other face thereof opposite the handle, the combination therewith of an abutment on the handle in spaced 4 relation to the base, a loop of tape extending from opposite ends of the head toward said abutment and engaging the abutment on the side thereof remote from the head, the tape engaging the ends of the base, and a finger piece including a helical portion enveloping the handle and threadable on the abutment as a thread element, said helical portion when threaded toward the base and engaging the tape at opposite sides of the abutment drawing inwardly toward the base the portions of the tape between the abutment and the base and toward the handle, the tape portions being at opposite sides of the handle and immediately contiguous to said abutment, the tape portions so inwardly drawn then lying between the handle and the helical portion, the degree of drawing in determining the tautness of the tape and retention of the head upon the base, the amount of drawing in being proportional to the amount of threading of the helical portion toward the base.

3. A mop as defined by claim 2 wherein the helical enveloping portion comprises a coiled wire helix of considerable rigidity.
