. Be it known that I, WILLIA WATTIE a citizen of the United States, residing at Worces-- ter in'the county of Worcester and State of l\lassachusetts,have invented certain. new and useful Improvements in Straw Matting, of

which the following is a specification.

-' The invention to be hereinafter described .larly to improvements in the selvage edges of such matting; whereby the production of a uniform and eneu thickness of matting. with-. out liability of unraveling is produced.

Heretoforein tl e ordinary method of .weaviug strgz-w matting'to form the selvage edges, the filling-straws, \7hich are inserted sepa-' rat-ely and alternately from oppositesides'oiiv the loom, have had turned-in ends which are of reduced size and extend over and beyond the selvage-cord, turned over said cord, and

brought to the upper. surface of the matting, where they are bound or held in place'byth'e up of the lay The projecting turned-in ends upon the upper surface of the matting have been trimmed-off; but this leaves the finished 1 vmatting in an unsatisfactory conditionupon thev upper surfacelast trimmed, and the ends.

willproject somewhat and aii'ect the appear-;. ance, as well as the wear, of the matting at its edges. It has been customary to some ex tent inorder to overcome the objection of trimming the projecting turned-inends ,of the straws on the face of the matting to turn the said ends back under the warp-threads, interweaving said turned-in ends with the warp threads or cords of the matting between the selvages, and then to bring theends upon the lowersurface of the'fabric. The objection to, this is that the series-0t" loops formed'by turn ing the projecting ends back under the usual warp-threads between the selvages produceslongitudinal ridges upon the upper surface of the matting inside the selvage edges, thereby increasing: materially the thickness of the matting at its edges over the thickness of the body of the matting. This is-a serious objectioirandv not only aifects-the appearance,

but presents ridges, which wear rapidly; a,

I .Y-The' objectrof my present invention is to overcome both of th'e'objection's hereiubcfo're' ducti -on;of undue thickness-at this point.

I;u weaving straw mattingwith my improved 'se lvage edges Iemploy an auxiliary or sup- ..plefnientalthreadiand the'n'ext of the .usual warpc'ords or threads and also extendingin 'thejdi rectionof the length of the matting par falls-l with and inside of the usual selvage "noted and: to'provide a straw m'atting'with improved-salvage edges wherein'the turned- -;in-;euds will be upon the lower surface of the matting andat the same time avoid the pro- 55 cord orthread The'reduced ends of the filling straws which are to beturned in extend 'over aud Q-nnder; theselvage cord or thread 'andun'derthe said auxiliary or supplemental cold or thread.'-r In addition to the auxiliary or supplemental thread or cord I also employ what is termed the V turn-over thread, which extends through an eyezor opening in the upper end'of a needleandis guided ina slot," so

that'the movement of said needle at the proper *tim'e'by mechanism to'be described will turn in or carryv the extended. reduced end of the.

filling-straw downand under the salvage cord or thread and u"nd er or against the auxiliary.

or. supplemental thread or cord and will-preof'thehnatti ng, the said turned-in end being jithus bound by the supplemental or auxiliary "cord'o'rthread and the turn-over threadwithout being interwoven with the usual warp threads .or cords of the fabric. On the nextsueceeding-piek of the filling-straw from the opposite-end .oi;' the loom onthe beating up of the lay the turnover thread will-be bound in to holdfthe turned-in end extending under the 'selvagecotd andz-the supplemental c'ord l "orthre'ad'; and thus the operation'is repeated alternately at each edge of the straw matting to'form. the selvage edge thereon. In the drawings l have shown only su'fficientofi a straw mattingwith my improved selvage edges to enable those skilled in the art tofiwhich myin'vention belongs-to. understand thesa'me.

Referring to thedra'wingsrFigure l" is a plan-view of sufli'cient of astr'aw matting to illustrate my'invention, some ofthe straws bcing shownseparated'from the remainder of the fabric to illustrate the manner of tying in, to'b'ehereinafter described. Fig. 2 is an edge view of the fabric looking in the direction-of the arrow d, Fig. 1. Fig. 3 showsthe under surface of the matting illustrated in Fig. '1. Fig. 4 is a diagram to show the relative positions of the filling-straws, the long'itudinal warp-threads, the selvage cord or thread, the supplemental warp or binder thread, and the turn-over thread, the parts being shown with the shed open and before the operation of the'needle to move the turnover thread. toturn in the reduced end of the I straw; and Fig. '5 shows the'position of the [several parts after the operation of the needle employed are larger at one end than at the other, and to'produce a selvage on either side of the matting these straws are-introduced alternately between the warp threads from v opposite sides ofthe loom, with the larger end leading, as indicated by the arrow @111 Fig.

4, while the smaller ends of the straws project beyond the sclvage warp-thread 3'7, and

in disposing of these smaller ends of the straws on opposite sides of the fabric it has heretofore been proposed to turn said smaller rise to the uppersurfaceat all, as would he ends back into the fabric and int'erweave them with the regular warp-threads 37. In the improved construction "of fabric which forms the subject of my present invention I have provided between the selvage cord or thread 37 and the nextadjacont regular warpthread of the fabric an auxiliary thread 38,

preferably disposed in 'near proximity and parallel. to the selvage cord or thread .87, and between said auxiliary thread and the next adjacent regular warp-thread of the fabric I employ what I will designate a turn-over thread 39, and in disposing of the smaller projecting ends of the straws I turn said ends over and around the selvage cord or thread 3?, under the auxiliary thread 88, and over the turn-over thread 39, the smaller ends of the straws projecting from this point toward the back of the fabric, from whence they maybe removed by cutting off, ifv desired.

I It will be noted from the construction of fabric-described that the smallerends of the straws are not interwoven with the regular warp-threads of the fabricand do not, in fact,

reached the fell of the matting.

warp-threads, and it will be also HOtOCLtllfliJ the turned-in andsmaller ends lie alongside of and parallel to the straws of which they are a part and on the same side of the auxilliary and turn-over thread as the body portion of their respective straws, the result of which is that on the beat-up of the lay the smaller ends are crowded close up to and to some extent beneath the body portion of their respective straws, thus obviating theirappearance upon the surface of'the fabric and the production of ridges, whichwould be subject to rapid wear. "In order that the manner of weaving my improved fabric maybe more fully understood,

reference is had to Figs, at and 5, in which the large end of the straw 40 is fed in the direc tion ofthe arrow 6, under the-turu-over thread 39,0ver the selvage-cord -37,- under the supplemental warp-.th read 38, and then regularly between the sets of warp-threads 37, the shed duringthis time bei u'g'open, as shown in Fig.

4, The small endof the straw i0 is left ex-- tending beyond the selvag'e-cord 37, while the turu-overthreadBi) is carried by a needle 13, which is given movement by any suitable formof mechanism, so as to carry said turnover thread from the position shown in Fig. 4 to that shown in Fig. 5 in the direction of the arrow, Fig. 5, whereby the'fturn-over thread 39 carries the reduced end of the straw a0 around the selvage-cord 37 and u nder the au xiliary thread 38, so that it"extends from over the turn-over thread 39 and toward the-back of the fabric. tion, the shed is now closed as the reed has On the following pick a filling-straw; from the opposite side of the layis inserted 'and passes under the turn-over tl1read'39, while it is in the position shown in Fig.5, and binds the same into the body of thematting on the beating up of I the lay. The needle v13, carrying the turnover thread 39, is then returned to the position shown in Fig. at, and the succeeding pick leaves a straw with the small end under the turn-over'thread 39', as shown in Fig. a, and the operation of forming the selvage edge is repeated in the sequence aboveshown an d outlined. v

It will be understood, of course, that the selvage is formed on each edge ofthc matting in the manner above described for one edge. thereof.

The advantages of a selvage formed by the disposition of parts as noted and by the use of the auxiliary thread 38 will be appreciated by those skilled in theart. The turned-in end of the straw is not carried to the upper surface of the matting, as would bethe case if'it were interwoven with the regular warpthreads of the matting, but extends to and upon the lower surface thereof, leaving the of the supplemental or auxiliary thread 38 the The parts being in this posi-v ioc turned-in end is bound into the body of the fabric, at the edge thereof, so that the turnedin end of the filling straw cannot become de-.
