To allwhomit ma Concern; l

Be it known t at I, JOHN C. BROoKs,a citizen of the United States, residing at Paterson, in the county of Passaic and State 5 of New Jersey,- have invented an I InprOvenient in VVarp Stolnlhlotionaoli which .the

following description, in connection with the' accompanying drawings, is' ab "specification,

v .like letters on. the drawings representing like parts. .Y v .,Theinv'ention :hereinafter described rey lates to Awarp stop motions `for'looms, and

" more `particularly to that type wherein a series of drop devices or detectors are supported by theV warpmthreads, which, upon breakage Orfundue slackness of one or more of said threads, permit such drop devices or' 'detectors to moveinto position for cdaction with suitable means for stopping the loom. 'This general type ofpwarp 'stop motion usu- Aally occupies a position between vthe warp beam and the shedding-mechanism, where the limited space precludes the use of a'large nlnber of ldrop 'devices or detectorsand as- 25 sociated parts ofthe ordinaryconstruction.'

In weaving certain classes of`fabrics, therefore, where a large number `of`...inewarp threads-'per unit of'width' are employed, the 'warp stop motionfdevices Ofordinary constructionvbecome impractical-ble. Moreover, v l where the drop -devices or detectors of ordi nary construction are lmultiplied in two or, at most, threerows transversely of the loom and lcrowded together in anl .attempt to adapt such stopmotion for use in weaving j fine fabrics, the drop devices' fail to work properly and rnuch' lint or fluff is produced. Withthc above facts in view the aims and purposes 'of the 'present invention are to pro- 10 vide a warp stop motion of high capacity 'which shallovercome the diliicultie's heretoforeexperienced'and be equally applicable for use in weaving the finer' fabrics having a llarge number of warp threads'p'er vunit of width or the coarser' fabrics having a vless number of such threads, and wherein the parts shall'be so related and contrived that i the drop devices or detectors may be properly guided and supported, and all Huil, lint,

5G or 'dirt be readily eliminated; `all of which A will hereinafter more fully appear in con- :nection with the accompanying drawings of one form. of means for carrying the invention lnto practicaleect, it being understood that in its true scope the invention is defined by the claim.

Inthe drawings z-fFigure 1 is a side-elevation, of a portioriof a loom showing the Warp stop 'motion of the present invention associated therewith, some of the parts being shown in section; Fig. 2 is an enlarged detail of one end of the stop motion devices; Fig. 3 is a section taken o n the line 3-3 oi Fig. 2; and Fig. 4,' is a top or plan'view of the parts lshown by Fig. 2', with portions broken away.

The loom frame 1 may be of any usual or desired character suitable for the support of the loom parts. Rising from'the loom sides vare the stands 2 between the shedding devices or heddles V3 and the whip roll 4.- over which the'warp threads 5 pass from the warp beam, said parts, as wellpalso as the lay 6, its actuating means and the shipperv 7 connected to the loom starting and stopping devices, may be andare shown as of usual 'construction and' operation. i

Secured on the stands 2 at opposite' sides of the loom frame, as by Ameans of the bolts 9., `are the end supports 8, constituting one vform of end 'framing for the parts bof the warp stop motion'. vllxtending transversely of the loom and supported at the' upper portions of the end supports 8, are the warp rods'lO, over which th'e warp threads 5 pass and by which they are sustained. InA the present form of the invention each ofthe warp threads between the warp rods 10, Fig. 3, sustains avdrop device "or detector ll and in order thatjthese maybe more oonveniently and compactly assembled. they are preferably formed of wire shaped generally as indicated by Fig..3,-and having a. head portion Ito engagea warp thread and a tail or extended-portion for a purpose to herein-4 after appear.

Mounted on the end supports and extending transverselyof the loom are the detector guides for maintaining the detectors in posi-- tion and directing them in their movements f, when permitted to'drop'by broken or unduly slack Warp threads.' In the illustrated form of the inventionl these detectorguides comprise an upper, a lower, and an intermediate reti'eulated structure, the openings of which-may `berso closely related, that re'- g'ardless of the number of Warp threads in vthe fabric' per. unit of width-,"the required number of dropdevices or detectors may be employed, 1t being only necessary to lnsert or removedrop' devices or detectors to correspond'to the special requirements of each inments of the stop motion device. 4

The upper .detector guide comprises'- a framework'12'havingv secured thereto a se"- riesof-crosse'd 'Wires 13,` Fig,. 4, forming'- a wire mesh, )each of .the openings. of- `which dividual case withoutdisorganizing the elesweaty Fig. avm
