Abstract

The jack is used for raising vehicles and comprises a diamond linkage operated by a horizontal screw. The upper ends of the links pivot in the top block and move in synchronism using intermeshing teeth. The lower ends (7a, 8a) pivot in the base and have no teeth. The base is in two parts, the upper part (20) carrying the link arm pivots (9a, 10a). Its underside is angled to a central apex, this having a rounded profile (22) seating in a recess (23) in the lower part (21) of the base. Limited movement between the parts is provided by a spring loaded guide pin (26, 28; 25, 27) on each side.
