ABSTRACT:
A drive coupler uses a first and a second U-shaped coupler half of similar configuration with each coupler half having cutouts in the ends of the legs of the "U" forming half of a pair of holes for accepting peripheral grooves adjacent to the ends of a pair of shafts to be connected by the coupler. The two halves of the coupler are retained in a mating orientation with the ends of the legs of the "U" in an abutting relationship to capture the grooves at the ends of the shafts in the holes formed therebetween by a transverse clamp bolt passing through the coupler. In one embodiment, the ends of the coupler formed by the mated halves of the coupler are provided with grooves to cooperate with ribs in a frame encompassing the coupler whereby the coupler grooves are arranged to slide on the ribs in the frame to prevent rotation of the coupler while permitting a translational or push-pull motion. In a second embodiment, the holes in the coupler for capturing the ends of the shafts to be coupled are non-circular, and the grooves in the ends of the shafts are correspondingly non-circular whereby the coupler can be used to transmit rotational as well as push-pull motion in a shaft coupler assembly wherein the drive coupler is free to rotate.
