ABSTRACT:
This invention relates to a lifting jack device for use with automobiles and the like. The jack includes a chamber for receipt of pressurized air constructed of a generally toroidal shape so as to resemble the configuration of a spare automobile tire. The central interior of the chamber is provided with cylinder and piston means operable by suitable valve means to extend a jack arm portion thereof outwardly and under pressure so as to impart lifting force to objects to be elevated. The entire jacking device is particularly adapted for placement beneath an automobile to lift a wheel thereof as for changing tires. Accordingly, the jack includes a relatively flat base portion and means for controlling the suitable valve mechanisms positioned at peripheral portions of the chamber so as to be readily accessible when the jack is placed in operable position beneath a car body.
