5 clam (ci. 13s-sz) The invention pertains to heddle supporting frames and its general aim is to facilitate the removal and replacement of heddles relative to the frame.

More specifically stated, the invention contemplates the provision of a novel and advantageous mounting for the bars upon Which`the heddles are supported in the frame, permitting easy disassociation of the bars from the frame and presenting no obstruction to the movement of the heddles along the bar.

The objects of the invention thus generally stated, together with other and ancillary advantages, are attained by the construction and arrangement shown by way of illustration in the accompanying drawings forming a part hereof, in which: Figure 1 is a side elevational view of a heddle supporting frame embodying my invention.

Fig. 2 is a fragmentary elevational view on an enlarged scale illustrating especially the improved means for mounting the heddle supporting bar in the frame.

Fig. 3 is a cross sectional view taken approximately in the plane of line 3 3 of Fig. 2.

This application is a division oi' my copending application Serial No. 514,313, led December 15, 1943, now abandoned.

The heddle frame comprises briey, top and bottom rails I and II, preferably of wood, and end members I2 eac-h comprising a pair of generally U-shaped metal straps I3 and I3 having yoke portions welded together providing parallel end portions I4 spaced apart to receive between them the ends of the rails Ill and II, such end portions being suitably secured to the rails.

The present invention concerns the mounting of a heddle supporting bar or bars I5 within the frame so as to permit 'movement of the heddles along the bar without obstruction by the supporting devices. Moreover, the construction is such as to permit of lateral deection of the ends of the bars whereby the heddles may be removed from the bars, and to permit easy removal of the bars from the frame with or without the heddles. In general, each of the supporting bars is releasably secured at its opposite ends to the end members I2 by means of latch devices I6 forming the subject of my said application, Serial No. 514,313. Intermediate their ends the bars are supported from the 'adjacent rails I0 and II oi" the frame by means of one or more anchoring devices generally designated I'I.

The heddle supporting -frame is designed forA use with heddles It having hooks I9 at opposite ends, and the heddle supporting bars Il are generally channel shaped in cross section. Thus each provides one leg forming a narrow wall or heddle ilange III with a free edge portion exposed for engagement by the heddle hooks I9 and the other leg extended'to form a relatively wide anchoring member connected to the adjacent side railby one or more anchoring devices Il, two

such devices being herein employed in the case of each rail.

, In general, the latch devices I6 may comprise a detent member in the nature of a slide bolt 21 mounted for sliding movement transversely of the end member I2 and engageable in an end opening recess formed by the channel-of the supporting bar to hold the latter in normal position. As shown, the slide bolt is inv the form of a iiat plate slidable in the end member I2 o! the frame and having its inner end position entered between the legs 2li and 2I of the'bar. The plate is mounted on the upper end of a leaf spring 2! anchored to the outer side of the end member I2. The spring is yieldable inthe. plane of the frame for the purpose of permitting the movement of the slide bolt outof the channel, and the bolt carries a transverse lug 3U for holding the bar in its deflectedposition, the device having been released and restored' to `normal position after deflection of the bar. The slide bolt 2l is apertured to receive slidably a bent upper end portion of the spring and the spring is yieldable transversely of the frame to permit disengagement of a U-shaped latch member.3I normally engaging with oneedge portion of the end member to hold the bolt against accidental withdrawal from the heddle supporting bar.

" In the present preferred embodiment of the invention, each anchoring device comprises a rod 32 extending through a hole 33 in the rail and having a connection with the bar disengageable by a short movement of the bar relative to the rod and'including in the present embodiment a hook 3l. The outer end of the rod is threaded for reception of a nut 3i clamped in position in a recess in the rail by a plate 3'6, the latter engaging a collar Il on the nut. By a rotational adjustment of the nut 3F the position 'of the rod 32 relative to the rail may be adjusted as may be desirable to compensatefor any bowing of the rail.

The hook u of the rod l2 is secured to the supporting bar along the upper edge thereof and therefore in overlying relation to the-channel. The upper edge of the bar is formed with transverse flanges Il carrying lugs 4I shaped to form loops or, open ended sockets for receiving the hooks (Fig. 3) Each hook u is preferably formed with a flat side engaging the flange Il Ato hold the bar against turning. The lugs Il are made relatively short so that with the one end of the bar shifted laterally clear o! the end member I2, the bar need be moved longitudinally only a short distance to disengage it from the hooks 3l.

It will be observed that by the construction provided for supporting the heddle bars in the frame, the heddles may be moved along the bars without interference or obstruction by the anchoring devices Il. Moreover, when desired the heddles may be removed from the bar or new heddles placed thereon simply by releasing the bars at one end from theirconnection with the frame and swinging such ends laterally into a deflected position at one side oi' the frame, the bars being held in such deflected positions by the lugs as shown in Fig. 3. The construction also permits removal of the bars from the frame with or without the heddles on the bars, and this by simply releasing the latch devices Il at one end of the bars and imparting a short endwise movement to the bars after swinging the released lends into. deflected positions at the side of the frame, the length of the disengaging movement being determined by the length of the hooks. on the anchoring devices.

I claim as my invention:

. 1. A heddle frame comprising top and bottom rails and end members connecting said rails, heddle supporting means carried by the frame including a bar, an anchoring device carried by one of said rails and having a connection with said bar intermediate the ends thereof and means connecting the ends of the bars to said end members including a latch device carried by one of the end members and disengageable from one end of the bar to permit lateral deflection of the bar out of the plane of said end member,

the connection between said bar and the anchor- 'v ing devicepermitting disengagement of t-he bar from the device by moving the bar a short distance endwise when the said one end thereof is deflected out of the plane of the end member.

2. In a heddle frame having a side rail and an end member perpendicular thereto', a heddle supporting bar having a free end terminating adjacent the inner side of said end member, a latch,
