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 substantially parallel forks having enlarged flattened outer ends projecting laterally away from each other in a common plane and provided with pin-receiving openings with parallel axes. The forging operation provides each fork with the appearance of a 90.degree. twist. After the blank is formed the forks are twisted on their axes in directions that will substantially eliminate their twisted appearance and will turn their enlarged ends into spaced parallel planes with their pin-receiving openings in axial alignment.
