and H, preferably of'woodyan'd end-members 12,

each comprising a pair of generally Ues'haped straps I3and I 3 having yoke prtions weldedtogether and providing parallel end portions I4 spaced apart to receive between" them the ends of the rails lfl'and H, such 'end portions being The'present invention concerns the" mounting Within theframe v-of'apair of heddle supporting bars I so as to permit-iof.-' detachment of the "ends of the'barsfrom the frame andthe shifting of the bars into a position suchas to permit easy removal of" the heddles'fromthe frame-:and th'e 'tion, thefree end of the oi -permit loading or removal of theheddles 2 f I: i replacement thereof. In general, each off-the supporting bars I5 is releasably secured at its opposite ends upon the end members I2 bymeans of latch devices [6, and each is supported intermediate its ends from the adjacent rail 10 on of the frame by means of one or more anchoring devices I]. Y

' In the preferred embodiment of the invention,

the heddle supporting frame is designed for'use with heddles l8 having hooks l9 at oppositeoends. Accordingly, the heddle supporting bars l5 are generally channel shaped in cross section, with one leg forming a narrow wall or heddle flange 28 with a free edge portio -exposed for engagement by the heddle hooks I9 and the other "leg 2i extended to form a relatively wide anchoring me her connected to the adjacent'sidev rail ID or H by means of the anchoring devices I1, two

such devices being herein employed in the case of eachrail. Referring now to the embodiment of the. invention illustrated in Figs. 1 to 4, inclusive, each of the latch devices It comprises a leaf spring 22fastened to the inner side of one of the end members -l 2. The leaf spring is normally inclined relative to the end member 'and'carriesatits free end a detent element 23' in the form of: a finger projecting through a' notch 24 in the bottom'of-thechannel member; as best shown. in

Figs; 3 and 4 into the recess or. space formed by the channel. The detent element is dimensioned to'fit snugly between the legs 20 and 2| of the bar, thereby holding the end of the 'bar against lateral movement relative to the frame;- When it is desired to release the bar for shifting movement, the detent is shifted manuallyl'a short distance inwardly or away fromthe end member I2'into alinement with a'slot 25 merging or opening at one en'dinto the notch. .LMovement of the detent element into such position permits of movement of the supportingbar laterally into a position indicated at a in Figs; 2 and 4, at one side of the frame. It will be observed that'when the bar is thus shifted the detent?- is released from the bar-so that the spring-22;may be pressed against the frame member l2 to position the detent between said member and the end of the bar which is spaced a short distance from said end memberpas shown in Fig. 3. i

I With the detent held manually in position against the end member, the supporting bar. may

be shifted reversely to a position designated b on the opposite side of the frame. In this posibar is exposed so as. to

against accidental movement. "the upperend of the leaf spring 29 is "bent over to project through-an opening in the slidebolt '21 and is extended to form a U-shaped'membe'r 3! engageable with one edge portion ofthe end -member I2, the spring being biased in a direction "to-move the bolt inwardlyandalso to move the An important feature of my invention resides in the utilization of the latch device for holding the heddle supporting bar in such heddle loading position b. For this purpose, the leaf spring 22 is provided with a latch element 26, herein in the form ofa second finger somewhat longer than the detent element 23. When the bar is shifted into its heddle loading position b the leaf spring 22 is released by the operator so as to permit movement of the latch element 26 into position behind the anchoring leg 2| of the bar, this being the normalposition of the latchdevice. It is-to be observed that because the latch element'ZB engages the outer face of the anchoring leg of the bar the heddles are free. to .slide. alongthe Moreover, since heddle flange of the bar. the bar is held in this position, while under stress, it is held firmly by the resiliency of the bar so that the operation of removing heddles from: the bar or replacing them? thereon is greatly facili- :tated.

In theembodiment of the inventionshown in Figs. 5;.to 8, latchdevices iii are employed. In thisinstance, each device comprises a 'detent member in the natureof a slide bolt 21 mounted -for sliding movement transversely of the end members I2 and engageable in an end opening recess formed by the channel of the supporting bar to hold'thelatter in normal position. i For a reason which will presently-appear, the supporting bar in: this instance occupies a reverse position from'that of Figs; 1 to 4, withithe heddle flange of the channel bar disposed'on the side remote from the observer (Figs. 5 and 6).

Herein-the slide bolt 2! is in the form. of a flat-plate supported in a slot' 28 formed in the 'two straps lil and I3 constituting the endmem- 'ber I2 (see Fig. *8). Its outer end is connected wi-ththe free end of a leaf spring29 anchored to the outer side of the end member I2v andacting tohold the slide with its inner-end entered between the'legs 20 and.2l of the bar. At its inner end, the slide carries a lug 30 disposed above. the channel leg 20 and projecting laterally-to one side face of the frame. Upon withdrawal of: the slide bolt against the action-of the spring into a position between the frameirnember and the end of the bar (this positionbeing shown in broken lines= in'Fig'. 8), the-bar is released for lateral shifting movement. After the bar has been shifted into the dotted line position a of Fig. 8, the slide is. released to the action of the spring, positioning the lug 30 for engagement with the anchoring leg 2| of thebarand-leavingthe:heddle flange 20 unobstructed for the removal or replacement of the .heddles.

The latch device I6 is preferablyconstructed so asto coact with the frame in the normal position'of thedevice so as to be heldby the frame U-Shaped portion 3| transversely of theyfralme into engagement with the end member.

The anchoring devices" by means of which the heddle supporting bars are supported intermediate their ends are preferably constructed to permit of adjustment to compensate for any bowing of the rails I 0 and H incident to the application of transverse forces thereto in the use of the frames. For this purpose, each-"of such an- For this purpose,

choring devices comprises a rod 32 extending through a hole 33 in the rail and having a bent inner end to form a hook 34 for attachment to the supporting bar. The outer end of the rod is threaded for the reception of a nut 35 clamped in 3 position in a" recess in the rail; by a plate 36, the latter engaging a collar 31 on the nut. By a 1'0- tational adjustment of the nut 35, the position of :ixthe rod 32 relative to the rail may be adjusted as may be desirable to compensate for any bowing of the rail.

, Thehhook-34-ofthe rod 32 is preferably se- 1 curedto the supporting bar in such a way as and thehook 34. has a fiat side which is held in position against said surface by a lug formed integraliwith the flange 39 and curled or looped around the rod, as shown in Figs. 6 and 7. The lugs :40 arerelatively short so that'withiione .end of the heddle supporting bar shiftedqlaterally ,clearofwtheend member l2, the bar, need'be moved longitudinally only a short distance tOLdiS' engage it: from the hooks-34.

In view of the fact that the upper; heddle supporting-bar hfiSfllfiS' channel =opening upwardly, itis desirable that provision-bemade for theremoval of lint which may be deposited in the chan- .nel.- For this purpose, a series of slots 4i may be provided along thechannel near the bottom thereof, such slots being, in the present instance, formedin the anchoring leg 2l thereof.

It will be seen that through the provision'of latch-devices lfiror I5, I have provided for the mounting of the heddle supporting bars so as to facilitate placement of the heddles inthe-frame .of'.their removal therefrom.- In each instance, the latch devices are operative not only to hold :the bars in their normal or operative relation' to the frame but also to hold them finmly against the normal resiliency of the bars, in position to permitof eas handling of the-heddles.

In the embodiment-shown -in Figs. l to 4,-the latch device is manipulated (to release the bar) first into aposition; to (permit lateral shifting of the bar in one direction, to the position shown at a in Fig. 4, the-detent element 23 being manually held in alinement )Withthe open; ended slot;.25 duringsuch movement. :Secondly; the spring is compressed against the end member 12 and into positionbetween this memberand the end ofthe bar, whereupon the latter may be swung to the vopposite or b position. Finally,-the latch is released so that the latch elementZG movesinto position to engagewith the anchoring leg;2| of the bar, leaving the opposite'orv heddle supporting =leg-unobstructed for the. sliding movement of the heddles.

' In the ;case of the embodiment shown 'in' Figs. 5 to 8, the. slide bolt is shifted against-theaction of the leaf spring-29 from the normal or operative position shown in'Fig. 6 to a withdrawn position inawhich' the bolt isremoved entirely from between the two legs of the channel shaped bar. 'In this instance, withdrawal of the slide bolt releases the:bar for movement directly into its disengaged or heddle loading and unloadingposition. Upon movement into suchposition the slide bolt is-released to the'action of the spring-29,- thereby carrying thelug 30 into position-against the anchoring leg-2| of thebar.
