ABSTRACT:
Metal stock is forged into a blank consisting of a rod-like shank joined at one end to the inner ends of a pair of forks having enlarged flattened outer ends projecting laterally of the forks in the same direction and provided with pin-receiving openings. One fork is aligned with the shank and the other fork extends laterally away from the shank and then outwardly, with its enlarged end projecting toward the other fork. Both forks are then twisted in the same direction to turn their flattened ends approximately 45.degree. into spaced parallel planes, and the longer fork is bent to move its flattened end into a position in which its opening is axially aligned with the opening in the other enlarged end.
