My invention relates to a devicefor holdbearing members for holding thefU-'shaped ing the ends lof a dot fillingy in looms,'and rod in place with the U-shaped rod being more especially for means adapted to autoshown in cross-section; matically move out of the path of the lay of Figure 7 is a perspective view of a fabric the loom when the filling is pressed by the into which the dot filling has been woven, 55 lay of the loom andwhich will automatically and showing the dot filling retainer in opera-V fall into position to engage the ends of a dot tion. l Y i filling at the proper time. Referring more specifically to the draw- An object of my invention is toprovide a ings the numeraly 10 indicatesthe side porf l0 dot filling retainer which is adapted` to be tion of the frame of a loom which v has the 60 lifted out of operation by thedobby lever of ltransversely disposed rod 11 thereon on the harness mechanism of the loomV when the which the lay of the loom is mountedby dot filling is being' woven, and which is means of the upwardly projecting oscillating adapted to assume an operative position when rods 12 and 13, the lay y14 ofthe vloom being 15 the dot filling is being woven, and which is mounted on the upper end of the rods 12 and 65 vadapted to automatically hold the ends of the 13. l e

Myk invention is 7.0 vide a cord around which the shuttle of they adapted to be applied to a conventional type loom would pass the dot filling when said of loom which has the templeslS thereon, dot lling is being woven into a fabric.- The these temples being provided with the temresult of this has been that after the fabric ple lip 19. i

Aforth in the appended claims.

While I have described my deviceas be# ing adapted to hold the filling when dotsY are v being formed in the fabric it is evident that it VVcan also be used forholding any desired amount of filling even thoughV the filling lshould extend all the way Vto theedge of theV warp. It is Ievident that whenthe filling adapted to beheld by my device is extended `between the'warp all theV way to the edge thereof, thatithe fillingV retainer will operate iii the ain'el manner will check the ends ofthis filling even though they are woven into warp at the point at V which they are i crossed by the filling retainer.. This ar-v rangement allows dot or other pattern effects to be produced even to the edgeof the fabric,

described and; claimed in theY application canV be used for instance where solid strip is woven all the way across the'fabric as the filling retainer would then operate and cause the filling to Vbe retained eventheligh fthe vandit is evident that this filling 'retainer filling is wcveninto the warp even tothe Y edge of thel fabric. Itis also evident that Y thisffilling retainer could be used continu-v ously for holding the ends oftheV filling 'assit would only be necessary. to 'cause the lever 3l to be held in lowered position at all'tiines; Y

The warp threads ofthe'loem are de'sigg Y nated by the reference character'tZand fillerV threads are indicatedby the referenc'erchar/ acter 43. Y My invention is especially adapted to be used forplacing grounded orflowered or design effects inthe fabric, andY this is" done lby passing the colored threads 44' through certain strips of the I naterial at the same time that the ordinary filler threads' 143 are being placed therein, and these threads 44; are woven intothe points'l, 4G' and 47 of the fabric, and the portion of vsaid colored threads therebetween project above the ground of the fabric, and after thefabric is woven this fabric is passed through'ashearing umachine which vclips Ioff .the loose por# Ations Aof the thread ineludiilg the loped ends and leaves the design in the fabric. Y i In the drawings andk specification I Vhave set'forth a preferred embodimentfof mylin-z-l f vei'ition and although specific terms are. einploy'ed they are used in a generic and descriptive sense only, and not for purposes of limitation the'scope of the invention beingset wI claim- Y 1.V,In a loom, ateinple, Aa adaptedf'to! move to'and from said temple, lselva-ge re'tain-` ing hooks adapted'to be raised whenV the strikes the temple andto automatically lower Y when the lay leavesthe temple and 'connec-VVV tions between said yselvag'e retainingV hooks and the harness mechanism of the loom where- 1. l -by the selvage retaininghoolrs may ren# dered in'operativeat a. predetermined time` y 2., Ina filling retainer for a loom, temples on said-loom,'a pivoted member ass'oe'r'ated` i isa with each of the temples of the loom and being adapted to be operated by the lay of the loom striking said temples to engage the filling in a fabric, and means associated with` engage the filling at predetermined times.
