` l 4 `6 Claims. `This invention relates to means for supporting and locking theheddle bars of a heddle frame. I

Y One of the principal objects of my present invention is to providea heddle bar supporting and` Y 5 locking Adevice which is characterized by simplicity, economy of manufacture and efiiciency in operation when in use.

Another object of my invention is to provide a heddle bar supporting and locking means in which a leaf spring is utilized to bear directly upon the heddle bar and lock it in position in the support, and to also lock a center brace in position, supplementary means in the form of a lock nut also being provided to positively hold the spring in binding position against the heddle bar.

Another object of the vinvention is to provide a construction in which the support may be screwed into a wooden heddle framerail by means of the usual wood threads, and a locking nut may be mounted on the support on machine screw threads superimposed on the wood threads.

These and other objects will-more particularly appear as the description proceeds.

In the drawing in which I have illustrated one of the embodiments thatthe invention may take;

Fig. 1 represents a fragmentary elevational view of a portion of a heddle frame showing the invention applied thereto, the rend portions of several heddles being illustrated in position.

Fig. 2 represents a sectional view on line 2--2 of Fig. 1 looking in the direction indicated by the arrows.

Fig. 3 represents a similar view on the line 3-3 of Fig. 1.

Fig. 4 represents a view in perspective of the spring.

The same supporting. and locking means may be used in conjunction with the upper and lower rails of a heddle frame, and I therefore have illustrated the invention only in connection with the upper rail. The rail is indicated at 5, the heddle bar is indicated at 6, and the upper endsof several heddles are indicated at 'I. The support may be in the form of a pin 8 suitably secured to the rail 5. To this end I may provide the upper end of the pin, the lower end of which is flattened as at 9, with wood screw threads IB so that the pin may be screwed intothe rail. A reinforcing plate I I may be fastened to the under face of the rail, and through al1 openingin this plate the pin projects. The flattened portion of the pin is provided with a recess for receiving a heddle bar 6, `and this recess at its lower end has a shoulder I which-may be beveled upwardly and outwardly as indicated so as to tend to cam or wedge the (Cl. 139-92) l p heddle bar 6 against the support'wherr the bar is in lockedV position. I I

The' locking means for the bar may bein the form of a leaf spring I2,"'anchored.at one end to thezplate III by one of lthe screws I3 which'sev 5` cure said plate in position, at its other end being forked as at I4 and provided with a downwardly projecting prong or tongue I5. The forked end of the spring straddles the pin 8, and the spring is thus prevented from turning sidewise, while free to flex up and down, therefore fouling with an adjacent frame is prevented. The prong l5 extends downwardly in sufliciently spaced relation to the flattened portion 9 of the pin to allow for the insertion of the end of a center brace I6 between the flattened portion of the pin and the prong. The brace may have its upper end hookshaped, so that it may be snapped into position on the heddle bar between the support and the prong. The end of the prong is recessed at Il 20 so as to engage the upper edge of the heddle bar I5v and force the latter downwardly against the inclined shoulder I1.

The spring may itself be sufficiently strong to lock the heddle bar in position on the support.25 and to maintain the center brace in position, but in order to provide a more positive locking means I may utilize a locking nut I8 which is turned onto the pin 8 on machine threads I9 which are superimposed on the wood threads. The ma- 30 chine threads'V may extend the full length of the I pin except for the flattened portion of the latter, While the Wood threads need only extend a suincient distance to allow the pin to be screwed to the desired extent into the rail and to allow for any adjustments of the pin that may be desired. The locking nut is positioned above the free end of the spring and may be turned down into the position indicated at Figs. 2 and 3 so as to force the spring into binding engagement with the heddle bar and thus hold the latter rigidly in position in the support; This movement of the locking nut will likewise bring the nut into binding engagement with the spring so that the latter acts as a means to prevent accidental unscrewing of the nut. I

When it is desired to remove theheddle bar from its support the nut is unscrewed and the end of the spring lifted to clear the bar whereupon the latter may be moved outwardly from the recess.

The foregoing detailed description has been given for purposes of clearness of understanding of the invention, and of the particular form thereof chosen for illustrative purposes, but no undue 55 limitations should be deduced therefrom, as the appended claims should be construed as broadly as permissible in view of the prior art.

I claim:

l. The combination with a heddle frame, of a pin mounted on a rail thereof and having a shoulder adapted to receive a heddle bar, a spring mounted on said rail and having its free end forked and straddl'ilng the pi'n and provided with a prong adapted to engage the heddle' b'ar, and a locking nut mounted on the pin and adapted to be turned into binding engagement with the spring. v A

2. The combination with a heddle frame, of a pin mounted on a rail thereof and having means for receiving a heddle bar, and a2 spring'liaiving a portion atlone end adapted to bear against the heddle bar and also having? a portion str'addling the pin.

3. The combination with a heddle frame, of a pin-mounted ori-a rail thereof and provided with a shoulder adapted to receive a heddle'bar, a spring mounted Von the rail and having its free end providedv with a= prong adapted toengagel the heddle bar, said prong: beingl arranged i'n suciently spaced relation to the pin to allow of the reception of a center brace between the spring and pin, and a locking nut mounted on the pin and adapted to be brought into binding engagement with the spring.

4. The combination with a heddle bar support having means for receiving a heddle bar, of a spring having a portion adapted to bear against the' heddle bar', said portion extending in spaced relationship with respect to the support to permit the reception of a center brace between the spring and support.

5.- A heddlebar support including a pin having a shoulder adapted to receive a heddle bar, a spring adapted to engage the heddle bai` directly for locking it in position on the support, and means movable along said pin for holding the spring and bar in positive locked position.

6. A heddle bar support including a pin having a shoulder adapted to receive a heddle bar, a springl adapted to engage the heddle bar' directly for locking it in' position on the support, and a nut threaded on said pin for holdingthe spring and-- bar in positive` locked position.
