Abstract
Abstract A compressed gas machine in which a plurality of inflatable and deflatable bladders are attached between a pair of chain loops which are carried each by a pair of sprockets vertically disposed above the other to form a line of ascending and descending buoyancy bladders. As the buoyancy bladders pass the top sprocket, a dump valve communicates with the buoyancy bladders, exhausting the gas therein, and as the buoyancy bladders pass around the bottom sprockets, a filler valve is brought into engagement with the bladders and compressed gas is applied thereto, causing the bladders on one side to lift and continue rotation of the chain sprocket assembly. The output is taken through a shaft coupled to the top sprocket axle.

Claim 1
Independent Claim
192 words
A compressed gas machine comprising: an endless belt loop, said belt loop carried by and coupled to at least first and second sprocket members; at least one support means rotatably carrying said first and second sprocket members; a plurality of inflatable buoyancy bladders carried by said belt loop; said first sprocket members rotatably disposed within a liquid medium; a majority of said inflatable buoyancy bladders being disposed within said liquid medium; said second sprocket means rotatably disposed vertically above said first sprocket member; a compressed gas source coupled to a gas supply line; a filler valve coupled to said gas supply line; a cam coupled to said first sprocket means in operable proximity with said filler valve, said filler valve being adapted for axial reciprocating movement; each of said inflatable buoyancy bladders having a filler dump valve positioned for cooperation with said filler valve; a dump valve cam coupled to said second sprocket member; a dump valve disposed in operable relationship with said dump valve cam and being adapted for axial reciprocating movement and further disposed for cooperation with said filler dump valves; and an exhaust line coupled to said dump valve.
Claim 2
Dependent Claim
192 words
A compressed gas machine comprising: an endless belt loop, said belt loop carried by and coupled to at least first and second sprocket members; at least one support means rotatably carrying said first and second sprocket members; a plurality of inflatable buoyancy bladders carried by said belt loop; said first sprocket members rotatably disposed within a liquid medium; a majority of said inflatable buoyancy bladders being disposed within said liquid medium; said second sprocket means rotatably disposed vertically above said first sprocket member; a compressed gas source coupled to a gas supply line; a filler valve coupled to said gas supply line; a cam coupled to said first sprocket means in operable proximity with said filler valve, said filler valve being adapted for axial reciprocating movement; each of said inflatable buoyancy bladders having a filler dump valve positioned for cooperation with said filler valve; a dump valve cam coupled to said second sprocket member; a dump valve disposed in operable relationship with said dump valve cam and being adapted for axial reciprocating movement and further disposed for cooperation with said filler dump valves; and an exhaust line coupled to said dump valve.
