This present mop. is made from long strands which are equal totwice, the, length of the finished mop-head, andthe means for hold5 ing the threads in the form of the finished mop is such that when the strands become broken or matted from continuous use, the same, caneasily be disconnected from the expensive portions of the-mop structure, to; the end that the handle and the eleinents holdingthe strands, forming the mop head, can be easily disjoinedr from the strands for subsequent use with new strands.

Many arrangementshave been employed inthe past for holding a plurality of strands together in the form of a mop for various uses. Many of these mops are of inexpensive construction and when they become worn from use must; ofnecessity, be discarded. There are certain fields of endeavor, however,- where mops must be especially constructed and be of considerable size in order that they will be suitable for the application ofviscous liquids. These mops are expensive and it is therefore very desirable to. have arrangements wherein the worn or mat-ted portions of the mop-head can' be discarded and the expensive structure" elements re-erri; ployed with fresh strands This present invention'eontemplates a mop thatr'willserv'e many of these purposes and one which is particularly adapted to. handling bituruinous riiaterials, often hot materials such as are em: ployedin the building-up of roofs for buildings where it is quite common to employ several layersofi paper or sheet; felted materials and to successively impregnate each" layer with, normally, hot bituminous materials in order that truly water-tight roof be provided. With the advance of chemical knowledgemany synthetic materials are now being used as substitutes; for bituminous materials and these too having a potentiality for quicklywearing out the expensive mops employediin" this practice. My present mop is believ ed to provide an excellent solutionof this perplexing problem; I p V g The principal objectof my present invention, therefore is to provide a unique mopfconstructionfwhich permits the easy'reinovalof'wornor mattedfibers, of acceptedtypes; fromftheiniop. headancl to replace-the same withanew' dle'offi b er s' ofithesame or different types, with minimum loss and With means which permit even unskilled labor to. quickly entire? theold fibers of the? map-Hashim to r eplac th'ehrwifli'new material.

A furtherobject'of this present invention is to provide structural nieanswhich can be suitably madam give a sturdy audeasily usednidp structure in which the handle and mep-headporiienean' be 'us'ed with many replacenieiitsfo f tlie strandedmaterial of any-desirable types; foriiiin'g th e mopp'ropir 7 A further object of thisfin'vent'ion is. to proiiide clamp iri'gliie'ans whicli will'uiake it convenient to rern aniepj nylon; rayon,

Further objects; advantages and capabilities will be ap parent from the description and disclosure in the drawings, or may be comprehend-ed or are inherent in the dev ce.

.Rflfierring; more particularly to the disclosure in the drawingg-the, mop portion proper; 1-0; is 'made up, preferablytot? a-lalrge number of" fiber glass or monofilament Wands; as; 11L These strands are preferably very small in diameter in comparison to the natural fiber strands formerly used in mops of this order. When using fiber glass orjthe soricalled spun glass or nylon monofilanients both of; hichproducej excellent" mops," it is'preferred that the diameter of individual strands does not exceed tn .905 inch in' diameter. This produces a mophead; that, -because of the; large numbers of strands over the eotton or hemp or sisalstrands for'rnerlyused, will actually oarr-yout of the drop kettle a greatly increased amount offthe roofing liquid, whether it is the'biturninous varietyor the synthetic. roofing compounds. Both of these liquids are normally heated-to. increase their'flowing ability and are quite viscous and tend to stiffen materially as; they cool until ultimately theyapproach solidification. In; using the natural fiber mops nade'of cotton, hempand the like, it is found-that'the': twisted strands of'these materials soon would become filledrwith the rooting ma terial; and-this would cause amatting or'soli'dification' of the entire upper portion ofthe mop and this solidification gradually works toward the; end of the mop and the same then hasJto be discarded; The newer synthetic monofila= rnentrnaterials do not have; this matting propensity and the liquidisidrawn out of the. mass of strands, inuse very similarly to paint out of a goodpaint brush. This makes it much easier for the workman in" spreading the roofing rnaterial, because it permits him to cover a much greater area in ajgivenlength of time andthe roofing liq tid is actually quite fully drawn ourorthe mop-head.

Inthe past, many attempts have been made to employ the rnonofilament fiber' strands in mops but considerable di-fiiculty has been encountered in holding the strands in'place? For c'onsider ableperiod it was feltthat mops" couldonly be made of the monofilar'ne'nts by cementing the mass together at the handle end'of the mop. This In my'pr'esent drop, I providemeans' for binding tli'e'straiidsvery securely together using many times the pressure forrnerly' used on, for instance cotton mops. iiicreased'pres'sure is not only very desirable in that ithold's the. strands; which ten d to slide very easilyon each ungainly in place, but because oi the firmnessofth'e individual strands they are in no way injured by this greatly increased pressure.

A preferred form of binding the fibers together is illustrated in Figures 4 through 7, in which banding material is used in a circular form, and as is illustrated in Figures 6 and 7. The ratchet type banding devices such as are used in tightening steel bands on small packages, are used to put maximum compression on the bundle of strands, after the showing of Figure 4. The banding devices suitable for such small diameter bands as are required in this operation normally tighten the hands by gripping the opposite ends of the bands in separate clamping means and then by means of a ratchet, normally operated by a short lever, the two ends are gradually brought toward each other, by a step by step operation until the desired pressures are achieved. A locking sleeve, as 13, is then passed over the overlapping ends and the sleeve and the two ends are simultaneously crimped or notched together to form a fixed lock.

Prior to the compression of band 12 the assembly bolt 14 is passed through the center of the bundle carrying with it the dished locking washer 16. When the banding has been completed that portion of the mop which appears on the right, as viewed in Figure 4, is allowed to fall down over the portion shown on the left. This is easily achieved by merely grasping the threaded end of bolt 14 and shaking the same when held in the vertical position. This then produces a mop after the showing of Figure in which the band 12 will approach rather closely to the cupped washer 16. Band 12 is placed at the center of the length of the fibers and then when one half is folded down over the other half, the desirable feathered-out brush end is achieved similar to a paint brush.

Adapted for attachment to bolt 14 are the handle members consisting of the metal handle ferrule 20, to which any desired length of handle H may be secured. Fixedly secured, as by welding, to ferrule 20 is a cupped washer or socket member 22. This washer is proportioned so as to fit over band 12 and still permit the mop strands to be seated up in the dome formed by the washer 22. In the inner bore of ferrule 20 a washer as 24 is fixedly secured, as by welding, so that its lower surface is a continuation of the inner surface of the dome portion of cup 22. This relationship is best shown in Figure 2. Resting on washer 24 is an axially threaded nut washer 26 having a thickness normally about equal to the diameter of the bolt 14 with which it is employed. This washer is preferably not secured inside the ferrule in a fixed relationship, but dropped into the same so that it comes in seating abutment with washer 24 and any tendency it may have to turn when engaged by the threads of bolt 14, can be overcome by a small amount of roofing liquid which can be initially smeared on the outside of member 26. When the unit is in use, a re-supply of this material will be achieved by having reasonable clearance in the hole pierced in washer 24, so that the roofing material can pass up through this opening and keep nut 26 sealed in place. It is intended that it may be necessary from time to time to replace nut 26 and if it is made after the mode outlined it is only necessary to remove handle H and then with a suitable drift, which would be the size of the enlarged opening in washer 24, nut 26 can be easily driven out of ferrule 20. A new nut 26 will, of course, have new threads of suitable pitch to engage possibly the new and replacement bolt 14.

The final step in forming my mop is to engage the structure, as shown in Figure 5, into the cup and ferrule assembly of Figure 2 and then, preferably, by means of a socket wrench applied to the head of bolt 14 the mop proper is drawn up into cup 22 so that a very firm engagement is obtained. The mop is now ready for use.

When it is desired to replace the mop portion 10, bolt' 14 1s unscrewed from nut 26 and a new assembly, after.

the showing of Figure 5, may be readily inserted in lieu of the worn out unit. It is the usual practice to remove bolt 14 and dished washer 16 from the worn out mop. This is usually easily arranged in that even after extended use there normally is not an" excessive hardening of the roofing material in the head portion, consequently both bolt 14 and washer 16 are readily salvageable for reuse.

It is believed that it will be clearly apparent from the above description and the disclosure in the drawings that the invention comprehends a novel construction of a roofing mop and method of making the same.

Having thus disclosed my invention, I claim:
