Abstract:
1. Socket wrench-making parts adapted to form a wrench with opposite outer ends with which can be applied over and rotate non-circular elements of at least two sizes, said parts including: a left and a right external driver member means-receiving part each having a first outer end to be located at a different opposite longitudinal outer end of the wrench when the parts are assembled and an opposite second inner end, said left and right parts respectively having walls defining differently-sized, non-circular sockets in the first outer ends thereof to be located at the opposite longitudinal ends of the assembled parts and applied over differently sized elements to be rotated by the wrench, said sockets each having an end opening thereat onto the exterior of the part involved so that the socket can be applied over and its defining walls interlock with a selected element of corresponding size to be rotated by said wrench and an opposite end opening onto a first smaller driver member-receiving bore in turn opening upon a second ball member-forming part-receiving bore, said first smaller driver member-receiving bore having bore-defining walls adapted to interlock with an external driver member means sized to be inserted into the open end of the associated larger outer socket and then moved inwardly into the associated driver member-receiving bore where it interlocks with said left or right part involved so that rotation of the driver member will rotate the wrench and turn said element enveloped by said socket at the other end of the assembled wrench; a ball member-forming part adapted to be secured to and between the said second inner ends of said left and right external driver member means-receiving parts, the second inner ends of the left and right parts respectively having walls defining a pair of ball member-receiving surfaces, at least one of which forms a ball-receiving bore; said ball member-forming part having a ball-forming end adapted to adjustably fit in said ball-receiving bore of one of said left and right parts and a second end adapted to be fixedly mounted against the ball member-receiving surfaces of the other of said left and right parts; and pivot-forming first and second means permitting the pivoting of said ball-forming end of said ball member-forming part in the ball-receiving bore involved at least in a plane which includes a longitudinal axis extending between said outer ends of the wrench.
