ABSTRACT:
A positive locking turnbuckle has a generally cylindrical barrel with an internally threaded bore at each axial end in which terminal members are threadably received. Rotation of the barrel relative to the terminal members permits the overall length of the buckle and any attaching objects to be adjusted in conventional fashion. The barrel has a slot extending longitudinally between the ends and penetrating through the wall of the barrel into the respective bores. Each terminal member has a transverse channel or crosshole which can be rotated into a position registering with the slot in the barrel. Two coil springs are resiliently mounted on the outer surface of the barrel and each spring has a tang which projects through the slot of the barrel into the channel of a respective terminal member to prevent relative rotation of the barrel and terminal members and, thus, lock the turnbuckle in a selected adjustment condition. To adjust the turnbuckle, the tangs are temporarily withdrawn from the crossholes so that relative rotation of the terminal members and the barrel is permitted. During adjustment the coil springs remain captured on the barrel and after adjustment, the tangs are re-inserted into the crossholes of the terminal members.
