HEDDLE FRAME.

Application led August 27, 1927. Serial No. 215,805.`

My invention relates to heddle frames for lo'oms, and it relates more particularly to 1mproved means, in a heddle frame of the .usual type, for supporting the heddle bars intermediate their ends.

'The principal object of my present mvention is to provide improved means in a heddle frame for supporting the heddle bars mtermediate their ends, which will securely support said bars against undesirable motion and displacement, but which, however, will permit the bars to be quickly and conveniently mounted in and dismounted from the frame when desired.

In U. S. Patent No. 1,512,935, dated October 28, 1924, there is shown a device for supporting the heddle bars intermediate their ends which permits the bars to be easily and conveniently inserted in and removed from the heddle frame.

My present invention contemplates certain improvements in the device shown and de-4 scrlbed in the Letters Patent above mentioned, whereb the supporting device may be adjusted wit respect to the top and bottom rails of the frame, so that the heddle supporting bars will be properly positioned and the heddles will not bind on the supporting bars, or on the other hand be permitted too great an up and down movement thereon.

The nature and characteristic features vof my present invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is an elevational view of a heddle frame provided with a heddle bar supportingdevice embodying the main features of my present invention;

Fig. 2 is a fragmentary detail thereof, enlarged;

Fig. 3 is a sectional view taken approximately on the line 3-3 of Fig. 2, the parts being shown in the normal positions assumed while supporting the heddle bar;

Fig. 4 is a similar view, but with the parts in the openposition for the purpose of removing or mounting the heddle bar therein;

Fig. 5 is a perspective view of a bolt member constituting one of the principal novel elements of the present invention; and

Fi 6 is a similar perspective view of a slida le locking member, detached, constituting another of the novel elements of the dev1ce.

Referring to the drawings, the heddle frame there shown comprises top and bottom rails l0.connected at theirends bymeansofthe side strips 11. Extending from end to end of the heddle frame and arranged near the top and bottom rails 10, in the usualmanner, are the heddle supporting bars v12, on which hed'dles 13 are mounted in the customary manner.

The devices comprising the novel portion of the present invention are mounted at 'suitable locations on the inner edges of the top and bottom rails 10. Each of theseidevices includes a bolt member y20, having a shank 21, the end of which is threaded as at 22 in the manner similar to an ordinary wood screw, with the exception that the same is not tapered for the greater portion of its length.

The bolt member 20 is also provided with a head portion 23, preferably made by flattening and spreading the material of the'rod from which the bolt member`is formed. The head portion of' the bolt member is also provided with a recess 24, in which the heddle bar 12 is adapted to be seated.

Mounted on the head portion of the bolt member 20 is a slide member 30. The slide member -30 is provided with a'longitudinal slot 31, and an opening 32 extends from the slot 31 to the marginal edge of the slide member 30. The opening 31 is located approximately midway the extension of the` slot 31.

One end of the slide member 30 is bent over as at 33, and the bent over portion 33 is provided with an aperture 34, through which the shank portion of the bolt 20 extends.' In

this manner/one end of the slide member 30 is properly positioned with respect to the head portion 23 of the bolt 20.

` The other end of the slide member 30 is positioned with respect to the head portion of the bolt member 20 by meansl of a rivet 36 which extends through a portion of the slot 31 of the slide lmember 30, beyond the opening 32. The rivet 36 is secured in the end of the head portion 23 of the bolt member v 2G beyond the recess 24 thereof.

The portion of the slide member 30 adjacent the bent over portion 33 thereof is bent out of the main lane of the slide member, as at 35, to clear t e shank portion of the bolt los l and also to aord a larger seat upon the bent over portion 33 of the slide member.

A coil spring surrounds the smooth or unthreaded portion of the shank 21 of the bolt 20. Said coil spring 40 bears at one end against the bent over portion 33 rof the slide member 30, and at its other end against the surface of the inner edge ofthe rail 10 of the heddle frame proper. If desired, a washer 41 may be interposed between the end of the coil spring 40 and the bent. over portion 33 of the slide member 30.

The spring 40 normally tends to cause the slide member 30 to occupy a position as shown in Fig. 3 ofthe drawings, whereby the lip 37, which extends from one end of the slot 31 to the opening 32 of the slide member, will lap over and retain the heddle bar 12 within the recess 24 of the head portion 23 of the bolt 20.

The movement ofthe slide member .under the tension of the spring 41 is limited by the -bent over portion 33 of the slide member bearing against the Vshoulder provided where the flattened head 23 joins the shank portion 21 of the bolt member.

The operation of the device may now be readily understood. The supporting devices being. mount/ed in the heddle frames at desired locations upon the inner edges of the top and bottom rails 10 thereof, and the heddle bars with the heddles mounted thereon being placed lin the frame in the usual manner, with the ends thereof secured in position in the sidev strips 11 of the frame by fasten/ing devices of any preferred type, the slide member 30isl then manually pushed to the open position as shown in Fig. 4 of the drawings.

The heddle bar 12 is now inserted in the recess 24 provided in the head portion 23 of the bolt 20, and thereafter the slide member 30 is released and permitted to return to the normal locking position as shown-in Fig. 3 of the drawings, being thereafter held bythe coil spring 40.

The lip port1on`37 of thel slide member 30 will now serve to retain the heddle bar 12 Within the recess 24 of the 'head portion 23 of the bolt 20, and will securely hold the same against displacement-during the operation of the loom. f

When it is desired to remove the heddle supporting bar from the supporting device, it w1ll be necessary merely to again push and hold the slide member 30 in the position shown in Fig. 4 of the drawings, and the heddle bar 12 may then be readily disengaged fromthe supporting device.

Should Vit be found at any time that the heddle supporting bars 12 are so located that an undue tension is placed 'upon the heddles whereby the same will bind upon the heddle supporting bars, or on the other hand, should 1t e found that the heddle bars are'so positioned that the heddles are permitted too be eiliciently supported intermediate vtheir ends whereby undue lateral movement ofthe same will be effectively prevented, and that adjustment of the supporting device with respect to the top and bottom rails maybe quickly and conveniently made, so that'the heddle bars may at all times be properlypositioned.

Having thus described the nature and characteristic features of my invention, what I claim as new, and desire to secure by Letters Patent, is:
