Generally, the invention relates to novel and useful improvements in the construction and consequent mode of operationrof weft disengaging devices preferably adapted for bullion-fringe loom apparatus, the latter being of the type capable of producing simultaneously a number of widths of fringe by" having groups of warp threads spaced apart and weft threads adapted to be interweaved 3 respectively with each of said groups of warp threads. It is usual in this type 'of loom to mount weft-inserting hooks on the i lay and to, move the said hooks by positive actuating Inechanism'carried on the lay andpartaking of thejfswinging of the lay. To

accomplish the disengagement or knockingoff of the bullion strands or'weftthrea'dsi from their respective hooks when the strands have reached their critical positions preceding the formation of fringe, it; has been a pract ce to ut1l1ze a series of hammers positioned in spaced relation with respect to their respective hooks, the hammers being" fixedly mounted on a shaft attached to the breast beam of the loom, and the shaft itself being actuated to. reciprocating and synchronous movement by motion communicators and converters with or without the cooperation of springs, the power for the said actuation being derived from the main driving shaft or otherwise. 7

My invention relates particularly to a weft disengaging device adaptable for use plurally on bullion-fringe loom apparatus of the character.described'such that each-dis engaging device, after an initial adjustment with its respective weft-inserting hook, op-

erates statically, requiring no power andfunctioning free of timing or synchronization with the position of the said hook.

The main object of my'invention is to pro vide'ac. weft disengagingrdevice which neither consumes power nor contributes its in crement of vibration when the 100m operates either at normal or high speed. Afurther' object of my'invention resides in the structur e, arrangement of parts and mounting of my invention such that synchronization with the respective weft-inserting hooks is accomplished by a single-and facile adjustment of homogeneoustwist throughout the entire inside of the lay.

each'disengaging device, Another object-of my invention resides in -meansfor so con tr'olling'the strands as they are released from their respective hooks as to insure a length'and to keep the finished fringe on the These objects and other advantageous ends in the structure, arrangement, combiantion and cooperation of the several parts of my invention are now to be described, ref erence'beln'g had to the accompanying drawlngs, wherein like reference charactersdeslgnate correspondingparts throughout allthe views e,

'1 represents the lay of any well known' bullion-fringe 100m of the type aforeoutlined, and is provided with'the ordinary slide'bar 3 suitably mounted thereon. Se-

cured to slide bar 3 by means-of any conveiitional upright such as 7 is a weft-inserting hook8. 5 is a suitable standard utilized on' apparatus of the type herein and is afiixedito lay 1, the said standard having laterally and removably secured thereto a"reed"6 through which pass a number of warp: threads, the

group being designated theaccompanyin'gdrawingsby reference character 12. 11 is the weft or the material forthe strands of bullion in the manufacture of any width of"fringe and is positionally adapted'to be engaged by hook 8, as will be more fully described hereinafter.

2rep resents the breast beam of the bull lion-fringeloom of the type herein and-has a atfixed thereon byanymeans suchas screw 7 attachment rod 4 preferably positioned-on the upper surface, rear edge andalong the longitudinal axis of the said beam. r

It is to be noted thatFig. I and the descrip tion thus far. is mostly fragmentary; that; standard 5 is one of a series secured to lay 1 and si tuated therealong inalignment and at of a single width offrmge.

Reference is now had to a preferred form of the weft disengaging arrangement comprising my invention in adaptation with bullion-fringe loom apparatus of the type described herein. left 11, warp thread group 12 and the weft engaging part of hook 8 all lie in the same plane. of the horizontal when. the beat-up by reed 6 is: eifectuated, the said plane being appropriately space-d above thesurface plane of lay 1. 13, 14 and 15 are spines or fingers preferably parallel to each other and disposed transversely to the longitudinal. axis. of lay 1, the said fingers respectively projecting from spaced orifices of bearing rod 4 and being adjustably fixed thereto by any means such as. set screws passing through the upper surface of the said rod 1 and bearing against the aforementioned fingers. Finger 13 at a small distance from its bearing is bent to an angle of declination, the rear terminal of the said finger developing preferably into a forward and upwardly turned hook, the rearmost portion of the said finger extending somewhat beyond the rear edge of the position of lay 1 at the time. of the beat-up by reed 6. Spines or fingers 14 and 15 extend at their rear terminals to the rear edge of lay 1 at the time of the beat-up by reed 6, the said 14 and 15 respectively developing at their terminals into similar and adaptable conformations as shown in Fig. I of the accompanying drawings. 9 is an upright, preferably an inverted U rod aifiXed to the rear edge of lay 1 by any suitable means such as screw attachment, and is adapted to cooperate with the. rearm-ost. portion of. finger 1 1 for a purpose to be hereinafter described.

In reference to the operation of the bullion-fringe loom of the type herein in adaptation with my invention, lay 1, actuated and mounted by suitable means not illustrated in the accompanying drawings, reciprocates transversely to its longitudinal axis, while 2" slide bar 3 secured thereon is actuated. to

synchronous oscillation therewith, the motion of the said slide bar being longitudinal of the lay. At the backward movement of lay l in the oscillation or reciprocation of the same, hook 8 passes through the warp shed of warp thread group 12 to engage weft 11. The warp threads of group 12 are actuated in the customary maimer for the production of sheds by heddle frames, the: hecldle frames and the operating means therefor not being illustrated in the accompanying drawings. Weft 11 is similarly actuated by a heddle frame, not illustrated in the accompanying drawings, to raise and lower the said weft 11 in and out of the path of hook 8. On t the. return and forward movement of lay 1, hook 8 carries weft 11 to be interweaved with the group of warp threads and to form bullion strands. When hook 8 has carried Weft 11 to-the extreme'position, the disengag ing device or arrangement comprising my invention comes into play.

Reference is now had to the modus operandi of the. weft disengaging device in con-- junction with the bullion-fringe loom de- 0 scribed herein, with attention paid to the relative positions of the elements as shown in Fig. I, the said Fig.1 being repr entational of a period immediately preceding the disengagement of weft 11 from hook 8 by finger 15, this period being followed by Y beat-up of weft 11 by reed 6. At the of the beat-up, lay 1 is at its maximum ward position.

The weft engaging portion of hook 8 is preferably development of the tenninal thereof, being bent to the rear and at :2 angle of declination so that any bullion strand of weft 11 may be struck free of hook 8 by the upright part of finger 15. The said a: finger 15 by reason of its adjustable exte sion beyond breast beam 2 releases or knoeirs of? the bullion strand of weft 11 from hool; 8 a lay 1 in its reciprocation proceeds to it ward limiting position, as best undu from Fig. 11 of the accompanying drawi Finger let, similarly positioned and in spaced relation with finger 15, in coope 'ation with upright 9 momentarily thereafter enacts a tension service to weft 11 by temporarily vising a portion of the bullion strand between the posts of upright 9, this phenomenon assuring necessary tension on weft 11 for its beat-up in the web. Furthermore, the '2 tension service affords a lapse in time for the natural and homogei'icous twisting of released bullion strand throughout its lei in the formation of fringe.

As already intimated, after the release of the bullion strand from hook 8, reed produces the beat-up of any particular pick.

safeguard against the suspension of the n'ianufactured width of fringe from the v proper, to prevent the component frin from dragging or rubbing with the lay and 12".. extending beyond thereto, finger 13 heretofore described is provided. The said finger 13 assures a uniform rolling of the manufactured width of fringe without ezipos' the individual fringes to kinking, intertwn; ing and unparallel relationship.

It is to be noted that fingers 13, 1 1- an-rl 15: are adjustable relative to the position of heel; 8 and the amplitude of lay 1.

Thus my invention presents a simple, eco- 23-3 nomic and easily accessible disengaging device comprising the most fundamental of ele ments, easily accessible for replacement and repair and being adjustable to the conditions aforementioned, and being free of dynamic synchronization with any particular position ofthe weft inserting mechanism. The disengaging device has already been in use and has been found to function perfectly.

I wish it understood that the embodiment of my invention is solely for purposes of' disclosure herein and that there is no limitation to any specific construction in the dis closure; minorchanges in size, shape and arrangement of parts, variations and modifications of details may allbe resorted to without departing from the spirit of my in vention nor enlarging its scope within the appended claims.
