Application filed September 2, 1925. Serial No. 54,016.

These improvements relate to devices ordinarily known as mops, clusters, cleaners, etc., and, although the appended claims recite mops, it is to be understood that I contemplate as their full equivalent all such swabbing or cleaning devices mounted on a handle. The improvements are more specifically in the connection means between'the handleholder and the mop body or frame.

It is old to provide a mop body or frame having a handle-holder, with connection means between the two comprising a yoke on the mop body and an interfitting part on the handle-holder, with bolt means for clamping the yoke upon the handle-holder whereby the handle-holder may swing into various angular relations with the frame.

The user of the mop constantly desires to vary the angular relation of the handle to the floor or wall surface for particular purposes, for instance, to clean under low parts such as sofas, back of radiators; etc; but does not desire the angular relation of the handle to the mop body to be changing automatically during the cleaning operation. The binding action of the bolt in ordinary constructions may be great enough to hold the handle in any given angular relation, but in such case without the desired flex ibility when. the frequent changes in angular relation are desired to be made. for it is too inconvenient tobe continually loosening the bolt and tightening it again, and, unlesssuch bolt be made quite tight the mop body will flop about and turn on the pivotal connection and deprive the operator of the command of the device necessary for satisfactory use. 7 r

- It has been suggested heretofore to overcome the objections to the ordinary construction by means. for holding the handleholder substantially locked in various angular relations while yet providing the desired flexibility at the joint, but such attempts in this direction as have come to my notice have various objections both with respect to operation and cost of manufacture.

' The chief objects of the present improvements are to provide a simple, relatively cheap, strong and durable mop construction having the advantage of flexibility at the handle and frame connection while holding the parts together in any suitable angular relation and with the proper degree of locking force, and to rovide a simple, relatively cheap and lnghly advantageous and partsof the left-hand half of Fig. 3.

reliable form of flexible locking, connection suitable for use in a large variety of mop and duster constructions.

v The mop frame 10 is shown as being 7 formed in substantially triangular shape and of thin strip metals The mop frame may have any suitable form and be of any other suitable construction. The particular construction shown is advantageous in its simplicity and low cost and also in the fact that when the bolt 11 is removed the mop proper 12 comprising well known flexible fabric elements and a hollow body part may be slipped upon the frame 10 and as readily be removed from time to time.

- The free ends 13 of the frame 10 are turned in a common direction and in parallel arrangement and lie spaced apart facing each other and provide substantially a yoke construction.

The handle-holder 14 is formed of sheet metal and has forwardly-extending arms 15w terminating in a pair of circular plates 16 lying face to face and constituting a part or member which interfits with the yoke.

The bolt 11 passes through aligning aper-p I turesin the yoke members 13' and the plates 16 and I preferably provide lock washers 17 on the bolt as shown to maintain the bolt from working loose. t

On the circular plates 16 constituting a connection member carried by the'handleholder I provide a plurality of spaced-apart respect to the bolt. As shown in Fig. 4 they are formed by pressing the metal outward, and they provide what is eifectively a recess between the adjacent ones thereof. j

Towardthefree end of the yoke members 13 respectively I form another, projection 21 pressed inward and into the path of arcuate movement of the projections 20 and adapted to interfit with the adjacent ones thereof as shown in Fig. 4, whereby a lock is provided for holding the handle in any one 10G projections 20 in arcuate arrangement with 1 merely overcoming the force of a springy' tions 20 may be put into use.

of various angular relations to the mop body or frame. The projection 21 being spaced materially from'the bolt, although the connection member 16 is held by the bolt very closely in face-to-face arrangement with the yoke member 13 there is sutlicient resiliency in the metal to permit the opposing projections 20 and 21 to spring past each other and provide for slippage between the connection member carried by the body and the connection member carried by the handle-holder, so that while the lock between the parts is substantially positive with respect to all such strains tending to move thehandle into another angular relation to the mop body and as are encountered in the normal use of the device it is still possible, by holding the mop body in one hand and the handle in the other, or by putting a foot upon the mop body on the floor while holding the handle,

or by pressing the body upon the floor with the handle and then moving the handle, to

' swing the handle and the handle-holder into desirable to tighten the bolt to such an extent as to produce a typically frictional engagement as distinguished from a merely locked cond tion. In other words, the mop body will suitably be held in its desired angular relation to the handle when the bolt is tightened only enough to bring about an overlapping or interengagement of the look ing elements, and thus the desired changes from time to time may readily be made by detent which slips out of one pocket and into another to lock the parts in other predetermined relations.

In the construction illustrated the mop handle can swing from its position illus trated in Fig. 1 through one hundred eighty degrees, and thus only half of the projec- I prefer to form such projections through three hundred sixty These various an' 7 degrees, however, to simplify the assemblage of the parts.

I have also shown the projections 20 providing recesses between them on both of the .discslike parts 16, and a projection 21 on both of the yoke members 13. The double construction in this respect is advantageous since it provides abetter lock, prevents a typically frictional contact at one side, facilitates assembling, and provides the same somewhat decorative effect on both sides of the disc-likeconnection member.

The construction thus illustrated and described is exceedingly simple, is notably cheap to manufacture, and is peculiarly effective to produce the desired locking effect between the parts while permitting the change of locked relationship 'of parts in notably rapid, simple and easy way.

I contemplate as being included in the invention such variations, changes and departure-s from what is'specifically herein illustrated and described as fall within the scope of the appended claims.

- 1 claim: V

1. Mop construct-ion comprising a mopcarrying fran'ie having a pair of substantially flat free and resilient end portions face to face, a handle-holder having a pair of substantially flat free end portions face to face and adapted to have inter-fitting faceto-face relation with said free end portions of the frame respectively, the free end portions of the'frame and of the handle-holder having opposed interfitting projections and recesses adapted to interfit-with each other for releasably locking said end portions to gether, there being aligned openings through all of said end portions at a place materially spaced from said projections and recesses respecti ely, and a bolt or the like extending through said openings to hold said end por tions for pivotal movement relative to each other and in locked relation when the opposed projections and recesses are in inter fitting relation to each other.

2. In mop construction, a looped mop-carrying frame having free, resilient'end portions arranged in spaced opposition, there being registering openings in said end p01 tions, a handle holder having a perforated extension arranged between said end portions of the frame, means extending through said end portions and said extension for re taining them in clamped relation, and a plurality of opposed projections and recesses formed on said extension and said resilient end portions adapted to be brought into registratioii for holding the parts yieldingly in given angular relations.
