4 Claims. (c1.15 2 29) This invention relates to mops, and particularly to the kind of mops inwhich thehead is made up of lengths of cords secured to one end portion of a stick. i i i i One of the main objectsof the invention is improved construction of the mophead in which the cords forming the head are more securely held on the stick than heretofore, and which construction makes possible veryrapid and economical making of mops with a minimum of metal or other elements that have heretofore been employed.

Other objects and advantages will appear in the description and drawings. f

The particular structure comprising this invention will be more clearly understood by stating at this time that the web of cords fromwhich the mop head is made is not new in itself. The

invention resides in the construction resulting from the manner in which the web is secured to the stick. The web itself is made in a conven tional manner in which relatively long cordsare wound around a pair of generally parallel spaced strings to form a skein-like band of cords and which are later severed along a line between the strings and parallel therewith. Whether the cords of such skein are severed before or after securement-to the mop stick, or the particular manner in which the web of cords for eac h fmop', is fabricated is not a part of this invention. It

is suflicient that the mop structure of this invention employs a band-like web of cords folded over a string that extends along one edge of the web where the cords are folded over the string? Thesecords may each be made up of a plurality f rope-like lengths, and in Figs. 1 to 6 of the of the mop head is at a stage slightly beyond that shown in Fig. 4. i Fig. 6 is a sectional view through the mop head just before the final step of securing the head to a the stick. Fig. 1 shows the completed stage.

Fig. 7 is an enlarged, fragmentary elevational view of rope-like lengths of the material that may make up each of the cords that is diagrammatically indicated in the preceding views.

In detail, the mop stick I is provided at one side of its outer end portion, and spaced from the terminating end of the stick, with a pin, tack or nail Zprojecting from said side (Fig. 2).- This pin provides one type of means for securing one end of the web of cords thereto. v

The band-like web of cords for forming the mop head comprises a stout string, generally designated 3, having a row of cords 4 Jfolded thereover,

' said string extending along one edge of the drawings hereinafter described,it is to be under stood that the cordsare diagrammatically indicated, for clarity, without attempt to illustrate. any winding characteristics of strands making up the cords.

In the drawings, Fig. 1 is an elevational view of a mop head on the outer end of a mop stick.

Fig. 2 is an elevational view of the outer end portion of a stick to which the head is to be attached.

Fig. 3 is a part sectional,part elevationalview of a portion of a web of' cords that is .used to make up the m'op head, it being understood that in actual practice, the web portion is as long as" is found to be necessary and the cords are of any desired length. u "f.

Fig. 4 is an elevational view of the outer end portion of the mop stick; the web beingshown at the beginning of the winding step in theforma tion! of the mop head and its securement to the stick.

Fig. 5 is a second elevational view generally similar to that of Fig. 4 in which the development web and supporting said cords thereon, and string 3 projects at its ends from the ends of the web. .Oneprojecting end portion 5 of said string is secured, as by tying, to the pin 2 at a point spaceda suflicient distance fromthe first cords. on said web to enable winding the portiorlwofv said string that is between said pin and said first cords several times around the end portion of the stick I outwardly of pin 21before the first cords of the web are brought into contact with the stick. This end portion 5 between pin 2 and the cords at the end of the web nearest the pinis tightly wrapped in a spiral coil around the end portion of the stick outwardly of pin 2, which coil extends from the pin toward the terminating end 0f the stick adjacent the pin. Thus the cords of the web at the end of the latter nearest the pin will initially be brought into engagement with the outer end portion of the stick at a' point spaced from the pan and of the stick. i

At substantially the time when the cords of the web at the end of the latter nearest the pin come intoengagement with the side of the end portion of the stick, the direction of the spiralcoil winding is reversed, although the rotation remains the same,- and the edge of the web along thestring is wound back over the portion 5 of the string in a spiral coil that extendspast the pin a distance toward the handle'end of the stick.

' When the last cords of the web, or those most remote from end 5fof the string come into tight engagement with the side of the stick along the edge of the web that is supported by the string, the other projecting end portion 6 of the string is brought back over the cords in a spiral-coil- Winding to a point or positionabout over the pin 2, but preferably slightly beyond the pin toward .the terminating end of the stick adjacent said pin, and at this point the adjacent coils of the spiral-coil of the string are close together, as

fairly close to the end.

the web on the end portion of the stick, one of x, Y. the cords 8 of the web (Figs. 4, 6) is preferably wound around. the first layer or so of the cordsoutwardly of the end of the stick to close said end so that the stick will not contact the sur face to be cleaned by the mophead. After such layer or layers are secured over'the end-of the stick, the outer end of cord 8 may be laid alongside the outer end portion of the stick for se comment to the stick .below the remaining. coils of the web that are wound around the end port'i'on oi the stick; There: issno claim made to this particular feature in itse'lfi since heretotore cords in mop heads have been secured over the end of the men stick by one o-iit'he cords of the mop he'ad for the samepurpose. v I By the foregoing structure itl is seen. that each of the cords o'f'the' web is-ti'ghtly' secured direct- 1y against the side of the. map stick by'the: string supportingthe web, which" Would-not be. the case were a layer of the cords to be interposed betweenthe stick and one of the coils of .the weld along. the edge: that. is supportedz' by the string. This structure. materially contributes to the: tight securement of? the head to the: stick Another'important feature of my invention is the spiralrcoil winding. of. the web at the edge thereof along the string in: a'direction from the outer'en'd: of the stick toward. the handle and. past the" pin. This alsoxmaterialliy contributes to the'tight secur'ement. of the: mophead to the sticksince direction. in which the coil is formed at both side'si'ot' the pin *2 insures against any possible slippage of thehead on the stick away from the .endof the stick in either direction longitudinally'of the stick or transversely-thereof.

The final winding of theie'nd portion 6 of the string over the coils of thawebwhere the latter used; to designate the manner in whiclr the web is wound on the stick, it is intended to define a spiral coil the inner sides of which substantially iollow the cylindricalucontour of the end of the: stick, as distinguished from a spiral in which the sides taper axially of the coil -tofollow adifferent contour than that of the outer sides of the stick, orin which the successive coils are .in a single plane developed about a single center. 1
