10 Claims.

This invention relates to means for supporting the heddle bars in the heddle frames of looms.

One of the principal objects of my invention is to provide a heddle frame having an extremely simple and inexpensive, and at the same time eicient, supporting and locking means for connecting the heddle bars to, and holding them rigid with, the top and bottom rails o-f the heddle frame.

A further object of the invention is to provide a heddle bar supporting and locking means which occupies minimum space, has no projecting parts which might foul an adjacent frame of the loom, should the support turn partially sideways, and which can therefore be used with very narrow frames, and one which will adequately lock and maintain the heddle bar `in position, and which, at the same time, vmay be readily actuated to release the bar.

With these and other objects in View, which will become apparent as the description proceds, I have illustrated one of the forms that the invention may take, in the accompany drawing, in which,-

Figure 1 represents a fragmentary view in elevation, partly in section, of a portion of a heddle frame, showing my invention applied thereto, one of the heddle bars` being shown in position, with some oi the heddles disposed thereon.

Figure 2 represents a sectional view on the line 2 2 of Figure 1, loking in the direction indicated by the arrows, the heddles being omitted for clearness of illustration.

Figure 3 represents a similar view on the line 3-3 of Figure l.

Figure 4 represents a horizontal sectional view taken on the line 4-4 of Figure 3.

Referring more particularly to the drawing, one of the rails of a heddle frame, which may be the top rail, is indicated at 5, one of the heddle bars is indicated at 6, and the end portions of some of the heddles are indicated at 'I.

The heddle bar support indicated generally at 8, is iiattened at its outer end as at 9, and is provided with a recess as at I for receiving the heddle bar 6. The lower end of the recess I0 terminates in a beveled shoulder II which tends to constantly urge or cam the bar against the support when the former is locked in place on the support.

The upper end of the recess is cut in a double step as at IZ-I El', to allow of the bar being readily Ainserted into and removed from the recess and also to provide a clearance which will allow the lower corner of the locking sleeve as at I6 (after `g55 having been bent inwardly slightly toward the (Cl.I 139-92) opposite face of the sleeve, as indicated in Fig. 4) to move upwardly when the sleeve 4is moved into its unlocked position, to suiciently clear the heddle bar and allow easy removal of the same.

Sli-dably mounted upon `the flattened portion 9 of the support is a locking member I3 which may be in the form of a flattened split sleeve.

It may be manufactured from a piece of sheet metal recessed at one end as at I4, and at the other as at I5, and may be form bent so as to con- 10 stitute a slidable member for locking the heddle bar in position. The recess I4 is made of such dimensions as to allow clearance for the bulge `I5 which occurs at the junction of the flattened portion 9 of the support with the cylindrical por- 15 tion thereof, and on the opposite side of the locking sleeve I3, the distance between the split edges of the sleeve is sufficient to allow a clearance for the bulge, as shown in Figure 2. The sleeve may thus. be `moved upwardly sufficiently to clear the heddle bar to allow the latter to be disengaged from the support when it is desired so to do` The lower recess I5 is proportioned to engage over the :edge `of the heddle bar opposite the edge thereof engaged by the shoulder I I, so as to lock the bar against the support when the sleeve is in the position indicated in the drawing.

On the opposite side of the sleeve from that in which the recess I5 occurs, one edge of the split in the sleeve is so disposed that a corner of the sleeve will engage the heddle bar on the face thereof opposite the one which is against the support, as at I6 (Fig. 3), so that the bar is thus engaged on both sides of the flattened portion of the support or pin and held tightly against the latter.

y The support is suitably connected to the rail 5 of the heddle frame, as for instance, by being threaded, as at I'I, so as to screw into the frame.

A spring I8 may be utilized to normally con- 40 stantly urge thelocking sleeve against the heddle bar., and this spring at one end bears against a washer I9, which surrounds the cylindrical portion of the support, and which bears upon the upper edge of the sleeve, and at itsopposite end the spring engages Y.the protuberances 20 which are formed by clinching the shank of the support, after the washer and spring are assembled thereon, to thus form a bearing or anchorage for the spring `and prevent it from slipping along the support under the tension which is developed when the heddle bar is in position.

From the foregoing, it will be understood that -by shifting the sleeve upwardly or towards the inner end of the support, the heddle bar will be released and may be removed from the support for sliding the heddles 'I into position 0n the bar, or for adjusting their position thereon, and that when the bar has been replaced in the recess, by releasing the locking sleeve, it will be forced downwardly by the spring and maintained under the tension thereof in locking engagement with the bar. The pressure against the bar will, due to the action of the beveled shoulder Il, cam or force the bar inwardly against the support and maintain it in locked engagement therewith throughout its width. Thus the bar will be kept in a locked condition in which no loose motion or relative movement between the bar and support is allowed to take place.

In order to prevent the locking sleeve from coming off of the support when the heddle bar is removed, it may, after the support and the various elements of the locking device have been assembled, have its lower corner as at I6, bent inwardly slightly toward the opposite face of the sleeve, as indicated in Figure 4, so as to bring this corner into alignment with the shoulder Il, so that the latter will form a stop to prevent removal of the sleeve from the support.

The foregoing detailed description has been given for purposes of clearness of understanding of the invention, and of the particular embodiment thereof chosen for illustrative purposes, but no undue limitation should be deduced therefrom, as the claims should be construed as broadly as permissible in view of the prior art.

Having thus described my invention what I claim as new and desire to secure by U. S. Letters Patent is:-
