Abstract

1,117,615. Garage lifts. J. VILLARS. 1 Sept., 1965 [22 July, 1965], No. 37321/65. Heading B8H. A vehicle supporting frame is movable by a screw-and-nut mechanism up and down a pair of guide columns and is guided thereon by guide blocks, which may consist of greaseimpregnated brake linings or of nylon, the position of the guide blocks and their friction coefficient on the faces of the guide columns being chosen so that during descent only a predetermined fraction of the weight of the frame weighs on the bearing nut or on an obstruction. A safety nut is provided on the screw to support the frame if the thread of the main nut strips. When the frame engages an obstruction on lowering, the screw continues to rotate and the main nut disengages from the frame and continues to descend until a lever connected to the main nut actuates a safety mechanism to stop the drive motor. The screw-and-nut mechanism may be replaced by an hydraulic ram assembly.
