Abstract
This power assembly has a housing with upper and lower housing portions and a frame of adjustable height in the housing. The housing mounts a worm gear in one of its portions, and the frame carries a worm on a fixed axis meshing with the worm gear. When the worm gear is changed for one of a different diameter, the frame carrying the worm may be raised or lowered to change the center distances so that the worm meshes with the new worm gear.
