1. A jack, comprising:
- a jack platform, comprising an apron on an under side thereof and a plurality of lift cylinders each having a cylinder end attached to an upper surface thereof;
a cavity defined within said apron and a bottom surface of said jack platform;
a manifold mounted to said jack platform;
a first control valve block mounted to said jack platform capable of being in fluid communication with an air supply and said manifold;
a second control valve block in fluid communication with said cylinder side of each of said plurality of lift cylinders;
a plurality of air jets disposed through said jack platform in fluid communication between said manifold and said cavity;
an intermediate platform mounted to a piston end of each of said plurality of lift cylinders;
an air bladder, having a first end affixed to an upper surface of said intermediate platform and in fluid communication with said second control valve block;
a plurality of guide posts, each having a first end attached to the upper surface of said intermediate platform; and
,an object platform attached to a second end of said air bladder, opposite said first end, and to an upper end of each of said plurality of guide posts;
wherein said first control valve block selectively delivers a first flow of air to said manifold;
wherein said first flow of air is delivered to said cavity causing each air jet to raise said jack;
wherein said first control valve block selectively delivers a second flow of air to said second control valve block;
wherein said second control valve block selectively delivers a third flow of air to said cylinder side of each of said plurality of lift cylinders; and
,wherein said second control valve block selectively delivers a fourth flow of air to said air bladder.

Abstract
A pneumatic jack includes at least a base platform and a top platform. The base platform is configured to be supported by a plurality of pneumatic jets. The pneumatic jets are configured to raise and lower the base platform and endow the apparatus with the ability to hover. An air bladder, with internal baffling, is positioned between a middle platform and the top platform. As the air bladder is inflated, the top platform rises relative to the other platforms.
