Referring now to the drawings by numerals of reference, 1 is a rectangular frame of which'the top heddle bar 2 forms a part.

3, and 4 are the end bars of the frameand are connected to the bar"2 and the bottom frame bar 5 in any suitable manner.

For c :onvenience'in description I have referredto the elements 2, 3, 4 and 5 as bars, but as a matter of fact they will generally be frames consisting of a plurality of parts, dep ending upon the.- requirement of the par- .tl'cular element.A For example, the upper bai' Qis shown as comprising a plurality of inverted T-rails 6 Fig. G-between which are interposed inserts 7, the whole being secured together by fastening devices, as, for example,rivets 8 (sec Fig. l). By placing the T- rails side by side, slots will be formed extending longitudinally the top bar? to receive the headed heddles to bedescribed hereinafter.

` Loosely connected with the frame 1 and supported `thereby is a lower heddle bar 10 ofa complete Each slot consists of the narrow por- .v -tion 6a a'nd the wide portion which may comprise a plurality of- T-rails l1 spaced. apart and insulated `from each other by inserts of suitable insulation. Ly-- ing adjacent to and insulated from the rails 11 are cont-act str ips 1 2 arranged so as to cooperate in pairs between the rails 11. The several cont-acts l2 extendbeyond the ends of the bar l0, and' have their respective ends connected by bolts 13 and 14 serving as binding posts to receive the conductors 15 and 16 connected up with an electrical stop motn for a. loom and a suitable source of electric current-.Of course, it is obvious that an l in 'the bottom bar between-the spaced rails cause a manual agitation of the Arings and washers 18. `Oneadvantage in' providing the slots is to permit lint and other extraneous mattei' to pass down through said slots Vinsteadof remaining in the slots and covering theeontacts.V In order to facilitate the -removing of thelint, etc., I provide'. loosely 'hung rings 2l of. foiexa ni plc,'fibrous' material. P The oscillation -of the rings, due to the motion of 'the bottom bar, will have atendency to` preventlint gatltering on the contacts above tl1e \\'ash'ers 1S, but in the event that any lint -does 'acc'iiniulatein the slots above lthe''washer .-i, the .operator may .21 b running his hand along t-lic lower edge of the lower heddle bar below which a portion of the peripheriesof the rings extend. 't

j The lower heddle bar is opratively held ln .the frame 1 by the guiding stirrups 92 and' 93 which are rigid with the lower hed- `"dlc'bar and straddle the'fraine bar 5. De-

The urpose of`this will Ibe presently explaine .The lo'wer heddle bar is guided inthe slots 28 'forlnediby the end bars 3 and 4 of the frame. The heddles einploye'd in connection with the frame preferably consist of'a, single piece of metal, and may be eongenientlv s waged and lformed from a piece otn'ivn'e.`-` The v form herein shown comprises a bodyportion having an intermediately located elongated eye 29 with its inner and outer edges convex or rounded to avoid sharp edges which would be liable to injure the thread passing therethrough. The body ofthe heddle projects from opposite ends of the e. e and terminatesin an elongated lattene( -portion 30 :1t-'each end provided with a convex-head 3l. The fiattened portion at each end is disposed at an angle to'th'e plane of the eye 29 and preferably at approximately anangle of forty-live degrees so .that when the heddle is in the framev the tlatte'ned .portion il() will he free to slide in the i'onstricted portions of.the'

slots, but .will not be a'lile to turn in said .were rigid in relation to each other.

ranged in one frame in ditl'erent planes,the 'number of rows being hunted by the number of spaced T-ralsor slots provided in the frame. When the frames are assembled 1n a loom, as indicated in Fic. 1t, they are J caused to ymore up and down y the straps SA fastened to the upper bar il and the lower' har 5, as in the .easeoordnary'heddle frames. Frame D is shown in the uppermost' position ot' opening the shed and the frame E is in the lower-most position. When either frame is in the position shown at l)the heddles are all supported from the har i?, with their lower heads hangingfree in the stets of the lower. bar 10, bar 10 being held down h r the .springs ".ft and :'27 uiou the blocks land 33, which vare fasten@ to the top otz the har -This allows the lower ends ot the heddles free movement sidewise, so that they may accommodate themselves to the position ot' the threads and thus produce less wear in wearing. 'lhe same conditions exist with the frames in position E, excepting that tht upper ends of the heddles are free lo more inthat case. The frame in the position .ti is held down bythe tower straps S. 'l`he stress on the warp threads in the lower shed is transmitted through the heddies b v means ol their lower heads to the lower'bar 1() causing it. to move with relation to the har f2 against'. the pressure of the springs t and :2 until the bottoni of the stirrnps 2:2A and Q3 rest against the endsof the pins'Q-l and 25, thus limiting its further movement. As the lower bar l() is now. n'eal'cl to the har t2. the upper heads ofthe heddl'es will, project into the slots-of the upper bar 2 by a distance greater than tlie distance between the lower ends of the heddles and the contact pieces 12, thus making it possible for a heddle in the caseof a broken or slack thread to fall` so that the convex liead will hrdge the contact strips within its particular slot and cause the circuit to actuate a stop mechanism (not shown) and thus st op the loom. ,'lhus position E is the only position of the frames in which the heddles are able. to complete the electrical circuit, the bars 2 and 10 heilig at all other times at too great a distance from each other for the heddles toreach the contact strips. I am thus ableto keep the eurl'ent on the contacts ull the time andA avoid the use of external circuit-ln'eakers` as would be necessary it the upperand lower hars l :im also enabled. hy this means, to keep the heddies alwavs in tension. thus tending to keep them straifht t'or it' the bars 2 and l0 were tito frames were in the position shown at D, theheddles would beresting 'upon the contacts l and lifting the upper shed by means of the lower hea which would tend to'bend the heddles out of shape.' The springs 26 and 27 insure the bottom bar 10 remaining doivn at 'all times, except when in the position shown at- E.Y By making the heads f the heddles convex, the closing of the circuit is .insured because the headwill have a wedging action between the two coperating contacts. A good example of this is shown in Fig. i4, the 'framel to theleft being the'lower frame and the'la'st-heddle to the left being dropped.;Y l

By providing the elongated'flattenedportions'near the extremities 'of the heddles l 20 providemeans vto indicate which particular vheddlehas dropped. This will be apparent when it is considered that the operator will' lieddles which are in their proper relative L positions.l In order to protect the heddles. against 3o deterioration on account of 'rust or corrosion or .the like and alsoto provide for Veiiiciency of contactvbetween the heddles and the electrical contacts, I might find it expedient to plate said heddles with copper or some othe I 3 6 materialof'great conductivity.
