ABSTRACT:
A coupling assembly for coupling a threaded connection of a lead screw to apparatus to be linearly reciprocated thereby. The coupling does not allow any relative movement of the apparatus and threaded connection in directions parallel to the direction of reciprocation of the apparatus, nor does it allow any twisting relative movement therebetween. However, the coupling does allow relative movement between the connection and apparatus in planes transverse to the direction of reciprocation of the apparatus, the coupling flexing in response to force components in those directions that would be large enough to cause excessive wear of the threaded connection so that excessive wear is avoided.
