'The principal `object of this invention is the provision-of new and improved locking elements for heddle bars. A further object is the provision . of heddle bar locks which may be readily re (Cl. 139-92) 2 The parallel spaced heddle bars'3 support the ` steel’heddles 8 in the usual and well known man ner. ’The heddle bars 3 are held in spaced, par lallel‘relationship with one another and with the frame bars I by lmeans of the harness end pieces 4‘by extension through the openings 9 provided placed in the event that the lock becomes inop therefor ‘in the end pieces 4. The heddle bars 3ïare provided at their ends with openings III to erative due to wear in use. receive the locking pin II of the locking element A still further object is the provision of heddle bar locking elements which may be removed or replaced without the removal or dismemberment of the other members oi the heddle frame. Other objects are the provision of heddle frame‘harness ends possess of my invention, which permit the heddle bars to be securely held against movement relative to the harness ends 4. The locking structures of my invention consist of a combination of a lock pin I I and a securing ing new and improved heddle bar locking struc 15 elementu IZ. The securing spring element I2 is tures and the provision of heddle frames including held in place in the harness end piece 4 at one new and improved heddle bar locks which per end by providing this end I3 of the spring with a mit the elements of the locks which receive the bend permitting the spring to extend through the most Wear during use to be readily replaced. holes I4 and I5 of the harness piece 4.

Thus, the only por supplied with the usual heddle bar securing‘mem tion of the locking element of my invention re bers 2 to which the heddle bars 3 are connected. quiring replacement upon Wear is the locking pin The heddle bars 3 are held in spaced parallel re I I. This pin is readily removed and replaced by lation with each other and with the bars I by 50 unhooking the spring I2 from the harness end 4 means of the harness end pieces 4 which have by moving the spring suñiciently to disengage the inwardly extending ends 5.

A new pin is then placed upon the spring, inserted through to holes I0 of the heddle bars 3 and locked into place by hooking the end I6 over the harness end 4. Having thus described my invention, what I claim is: 1. A heddle bar locking structure comprising a pin adapted to movably extend through the end opening in a heddle bar, said pin being provided with an aperture in one end thereof, and an ele ment for securing said pin against movement out of said bar-end openings comprising a spring wire element including a substantially straight portion adapted to extend through the aperture in the 4 3. A heddle bar frame comprising upper and lower bars, harness ends for holding the upper and lower bars in spaced relation With each other, heddle bars supported by the upper and lower bars, said harness ends having openings to re ceive the ends of said heddle bars to removably mount the heddle bars on the harness ends, a pin inserted through openings in the ends of said heddle bars securing the heddle bars against movement, and a wire spring element extending through an aperture in the end of said pin secur ing said pin from movement out of said bar open ings, said Wire element being fastened at one end to said harness end and releasably engaged at the opposite end to said harness end by an angled portion including a hooked end. 4.
