Application filed September 11, 19,122. Serial No. 587,306'.

To @ZZ whom z'may concern:

Beit known that I, vWrLLIAM H. FISHER, a citizen of theUnited States, and resident of Brochton,county of Plymouth, State of Massachusetts, have invented" any Improvee ment in Mops, of which the following 4description, in'connectioii with the accompanying drawing", is a specification, like characters on' the drawing representing like parts.

'This invention relates to imrovem'ent'siin mops'and the general"objectV thereoffis to provide a more durableand morey ecieiit mep than has" heretofore'been produced.

One of the essential features' oflth'e' in' vention consists in' providingy a mop body, formed of assembled strands' of fibrous material, having one"or more eyelets' therethrongli introduced' by" separatinginthe strands withoutsevering the same', said eyelets being' adapted to receive' suitablefstuds or projections for holding' the 'mop' body upon the mop handle." Preferably the mop body comprises a bundle fof strands of fibrous materialhaving a yband enclosing' the same intermediate of its ends'fwith grommets passing through y,the band and thev portion' of the bundle therebetween. i i" Another feature of theinventi'on consists in providing a mop body of greater than the holder i-n which it is tobeclamped' so that the holder will lbefprevented lfrom injuring objects against which 'mop .is forced when in use;y

Another object of the invention is to prof vide a mop body' construction'provided with eyelets of the character zc'lesc'ibed which may be composed of soft twisted yarns',fbu'ndled' yarns, drop ply yarns, twine or-'knitt'ed or woven materials through which'the eyelets are passed by separating without severing the strands of yarn. y

Another object of the invention is to pro# vide a novel form of mop head-"or holder'` having' a rounded under surface which will not be liable to scratch' or injure th'effloor."

A further obj ect ofthe inventionisxtorV provide ya novel form of mop head having means for positively and' effectively engaging,V the mop body. I Y

Other objects and features ofthe invention Vwill more fully appear from A thejfoh lowing description and the accompanying drawing and will be pointed out in ithe claims.

A preferred embodiment of the invention 2 isa' vertical sectional view taken on line 2 2 Fig. l showing the members of the `mop head' clamping' theflnop" body there# between, fthe; stud loassi'n'gr'k through* the' eyelet inthe inop'bo'dy beingfsliownin elevation;

*The preferred' construction illustratedY in theV accompanying drawing; comprises a` mop head l cast' metal, preferably ahin'nnum,or'other meta-1^ whicl'i 'will' not rust,1hafving Ca" 'han"dle socket '2 in whichl a handle'y 3 is'se'cured by va pin vor' screw 4 and aii" ii`1tegral"uppe'r clamping plate 5 prefer# ably presenting-f a' convexedly curved under face 6. "The(mbphead'also'is provided with al'ower elamping'plate 7' having a preferablyvicfnrvd ripper surface 8* complementary tofl'the Linder 'surface 6 ofthe upper clamping' :memberl "The lower 'clamping plate de'- sirably is proyided with integral' studs' 9 which pass through'` suitable apertures inthe upper 'cylamping'plate and the; st'uds" are provided withscrewthreaded upper' end porti'onstbfifeceivepreferably vwinged n'u'ts l0 forI forcing Athe"c'lanrping plates together.

The under"si'irface'Il' ofthelowerclamping mentary recesses to 'receive said teeth,- these teeth 'actinglto' engage the mop 'body and more firmlyy retain Iit inE place when 'the clamping members are forced together by the nuts 10.

The mop body mayf be formed of anyv suitable fibrous material, either hand twisted or braided strands, associated to form a preferably flat bundle, or of knitted or woven material, or yarn of any size or ply.

As illustrated in the accompanying drawing the mop body consists of twisted strands 13 of material of any suitable length assembled to form a flat bundle, the bundle being enclosed by a band 14C of preferably woven material, the opposite portions of which are secured together by lines of stitching 15 located adjacent to the edges of the band and passing through the strands of the mop bodyz.

Suitable apertures are made through ope posite portions of the band and the mop body therebetween by separating the strands of the mop body and the warp and weft of the band without 'severing them. rlhis aperture is provided with a wall or eyelet which preferably is formed by introducing a grommet through said aperture, but may be formed by stiching or in any other suitable manner.

The means for forming the aperture through the mop body and band and for introducing the grommet in theY aperture thus formed is graphically illustrated in Fig. et in which the means for forming the aperture consists in thrusting a sharp pointed needle 16 upwardly through th-e bundle and its band, placing the tubular por-` tion 17 vof a grommet upon the needle and forcing the grommet through the aperture formed by the needle hy a suitable plate 18 which is forced downwardly against the ange 19 of the grommet as the needle 16 is withdrawn. A washer 20 is then placed upon the tubular portion 17 of the eyelet which extends through the mop Vbody and the lower end of the tubular portion of the grommet bent to form al flange 21 which is forced against the washer 20.

rlhe grommets are so located as to receive the studs 19 of the lower clamping plate so that the mop body can be readily assembled upon the head by thrusting the studs through the grommets and thence through the upper clamping plate 5 of the mop head and clamping the plates together by the winged nuts 10 which may then be readily applied'to the studs. When the winged nuts 10 are set upy the clamping plates are drawn together until they clamp firmly upon the grommets. The plates at the same time engage thev body of the mop so that when the mop is in use, and particularly when wet, the body will be firmly clamped between the plates. The presence, however, of the grommets prevent the clamping plates from being set up upon the mop body that the absorption of water by the mop body and the consequent expansion will exert such pressure as to prevent the unscrewing of the winged nuts when it is desired to dismantle the device in order to remove the mop. ,It has been found in practice that in the absence of the grommets such expansion may take lace as absolutelyj to prevent the dismant ing of the device.

`The mop `body desirably is of a sufficient width to extend well beyond the ends of the

clamping plates

5 and 7 so that injury to objects which may be struck by the mop will be prevented. Furthermore, the mop body when the nuts are screwed up tight will also form a protective covering for the longitudinal edge of both plates.

By reason of this construction a mop is provided from which the strands, forming the body of the mop, will not become de tached and consequently the undesirable shedding which frequently occurs in mops is prevented. A mop bodyjA is thus produced which is more durable than other mop bodies heretofore known. A mop body can readily be assembled upon the head and replaced when worn by unskilled labor.

rlhe grommets of the mop body and the mop head may be made economically of materials which will not rust so that an eX- ceedingly durable mop is provided.

It will be understood that the embodiment of the invention as disclosed herein is of an illustrative character and is not restrictive and that various changes in form and construction of the mop head and mop body may be made within the spirit and scope of the following claims.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is:

1. A mop comprising a body formed of strands of fibrous material to form a flat bundle, a band surrounding said bundle intermediate ofv its ends having a plurality of grommets extending through said band and bundle, a handle having a head compris ing a lower clamping plate shorter than the width of the mop presenting a rounded under face and having studs projecting from its upper face through the grommets in the mop body and a complementary clamping member also shorter than the width of the mop having a handle socket and apertures to receive the studs of the lower clamping plate and nuts on said studs acting to clam the plates together upon said grommets anld also to clamp the mop body therebetween whereby in use the mop body will be firmly held between the clamping plates, but prevented by said grommets from being so tightly clamped as to prevent dismantling of the clamping plates and mop.

2. A mop comprising a body formed of strands of fibrous material to form a flat bundle, a band surrounding said bundle intermediate of its ends having a plurality of grommets extending through said band and bundle, a handle having a head comprising a lower transversely curved clamping plate shorter than the width of said mop body presenting a rounded under face and having studs projecting from its concavedly curved upper face to pass through the grommets in the mop body and a complementary upper clamping width of the mop lbody having a handle socket and apertures to receive the studs of the lower plate and nuts on said studs aoting to clamp the plates vtogether with the mop body therebetween, the mop body when the nuts are screwed up tightly also forming a protective covering for the longitudinal edges of both plates.

3. A mop comprising a body formed of strands of brous material to form a flat bundle, a band surrounding said bundle intermediate of its ends having a plurality of grommets extending through said band and bundle, a handle having a head comprising late also shorter than the` a lower transversely curved clamping plate shorter than the width of said mop body presenting a rounded under face and having studs projecting from its concavedly curved upper face to pass through the grommets and a complementary upper clamping plate also Shorter than the width of the mop body having a convexedly curved lower face complementary to the upper face of said clamping plate and provided with a handle socket and with apertures to receive the studs of the lower plate and nuts on said studs acting to clamp the plates together withthe mop body therebetween, a series of teeth upon the edges of the lower plate acting to engage the mop body when the plates are clamped together, the mop body when the nuts are screwed up tightly also forming a protective covering for the longitudinal edges of both plates.

In testimonyI whereof, I have signed my name to this specification.
