Abstract

A screw jack intended for use with an automobile consists of four arms (1-4) of U section steel and joined by pivot bolts (5, 7, 11, 12) to form a parallelogram. The parallelogram is mounted on a base (9) and has a bracket (6) to support the weight of the vehicle. The jack is actuated by a transverse screw (13) which screws into a nut (14). The nut is supported in a tubular arm (15) so that when the jack is fully extended the screw is fully enclosed by the arm. In this position there is no risk of the user having his hands or clothes stained by the grease of the screw thread.
