9 Claims.

:'aThis:rinventionzrelates to mops .and clusters, -:and more-:particularlyto adevice for adjustably holding ;the:wire frame'of adry mopuponthe :end of an elongated wooden handle.

.r-neizobject: ofxthisinvention isto provide a clamping device-of the :above nature having meansfor 1universally= ttaching the dry mop framexto a handle in such a manner that the anoprmay swing through an angle of substan- .tially 180 degrees with respect to the axis of the handle-.andthe frame of themop in turn may be rotated.as.--much as desired about its own .axis, thereby permitting both surfaces of the mop :to-be used interchangeably, and the mop desired angular position aAlfurther object is to provide a mop joint r-structuremf .the above nature having a pair ofclam-ping jaws whichaare-adaptedto be held in. frictional contact with the straight cross- .banof the wire mop frame by means of a bolt passing through said jaws.

.A.further object-is to provide a universal mop .hOIderandhandle joint. having novel means for pivotally. connecting .the mop clamping jaws to .the .handle .ferrule plates.

.. Afurtherobject. is. to. provide a universal mop .holder. of theabove .nature which will be-simple in construction, inexpensivetomanufacture, easy to assemble and manipulate, compact, ornamentallin appearance, and .very...efilcient and durable in use.

""With these andhotherpbjects in view, there has been illustratedon the-accompanying. drawing one'form in which the invention maybe conveniently embodied in practice.

"Inthe drawing:

'l.represents a plan view of themopand universal handlejoint shown on a reduced scale. 2 is a full size vertical longitudinal sectional view through the. joint member.

Fig. 3.is a perspective exploded view of the several parts of theuniversal mop joint.

Referring now to .the drawing in which like reference numerals denote corresponding parts throughout theseveral views, the numeral It] indicates a standard formpf mop frame made from a twisted .pair .of .wires bent to form a straighticentral;crossebar1lI and a pair of oval end loops "|2"and"l3,said loops being provided with a multiplicity of soft dust-absorbent cords l4 wound therebetween.

In order to connect the mop frame It to a suitable handle member l5, preferably constructed of wood, provision is made of a pair of split ferrule members It and I1. Each of the ferrule members l6, 11 comprises avpair-v: of semi-cylindrical sections 5 l8 and I9 which are adapted to embrace asre'duced neck *formed .on theend of'the handleill3. "The: semi-cylindricalisections l8 and EN, asshown in Fig. 2, preferably .do not completely. surround? the entire surface of the reduced neck120 LiIliOIdBll'ltO permit the .:ferr.ule :members l6 and llclto'. fit ivarious sizes of mop. handles. :The semiecylin- 'drical sections l8 and" l 9 maytbe'z providedwwith' 1 0 one or more tperforations222 (two -:innthirrzinstance), through which a corresponding number 1of1small: nails or. tacks 2 Simay be 'insertedrand driven into the handle 2 l5. The .l'lower poi'tions of the ferrule members l6; and H are zprovided withv integral fiat platesi2kand-25, soiconstrncted that :Whenisaid ferrules l6 :and' I1 :are'aassembled upon therhandlew I 5,-the flat plates e24 *1an'dz25 will lie in close parallelrrelationship.

For connecting the. mop: frame-r lot'tOi. the .fer- 'rulemembers 16. and I1 ,3 provision .is: maderof ixa pair of clamping jaws-.25 randwt21: whiclmare adapted to be located .onopposite sides-of. .the .flat. ferrule plates .24. andw25. The; forward ends of said jaws 26 and 21'are-sprungaoutwaltdly slightly along the lines and::43=and.-are-rprovided with opposedintegral angular sections 28 and .29 which are adapted to: frictionally rembrace the intermediate straight.- central section H1 of the mop frame 10: in-such amannenasto, permit the mop. frame to be rotatedabout'ssaid" central section I I "as an axis.

order -to .pivotallyconnectxthe-,-clamping jaws 26 and 21 to the ferrule plates 24 and .25, a pair. of round apertures 30 and-3t are pierced through the jaws;26 and 21, and are adapted-to fitabout a pair of drifted-.pivottubes32.-and33 struckup fromthe outersurfaces of-the body of the ferrule plateslz l and 25in opposed relationship. The tubes 32 and.33 are preferably spun over or outwardly. flattened to permanentlyhold the clamping jaws upon the outside of the ferrule plates. Therferruleplatesi i1and 25 are provided near their outer. ends witha-pair. of arcuate .slots 34 .and .35..concentric with thetubes .32- andi-33, and theclamping jaws.25..and.2] are provided with apairwofsquare apertures-36and .31 which, when-said. jaws 26 and.21 .are..assembled, register witheachother,-said,,apertures also being in alinement with the

arcuate slots

34 and 35.

A headed carriage bolt 38 is adapted to pass through the

square apertures

36, 31 and the

arcuate slots

34 and 35, and said bolt has the base of its shank squared to fit within the square apertures of. the clamping plates seated on the head of said bolt. The threaded end of the bolt is adapted to receive a winged nut 39 for tightly clamping the plates 241, 25 and jaws 26 and 21 together with sufficient force to hold the mop frictionally in adjusted position. The resiliency of the metal of the jaws 26 and 21 will cause said jaws to press outwardly against the wing nut and thus avoid the necessity of a spring washer.

It will be understoodthat when the nut 39 is loosened on the bolt 38, the

jaws

26 and 27 will spread apart sufliciently to permit them to be easily fitted over the cross-bar ll of the mop frame.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments of the following claims.
