  • Patent number: 3977815
    Abstract: Portable apparatus is provided for compressing gases such as air. The apparatus preferably includes a massive fly wheel, a gas compressor and a compressed gas storage vessel mounted on a portable platform. The fly wheel is rotatably mounted whereby it may be rotated by a temporary outside source of power and then the momentum thereof is used to power the gas compressor. The resulting compressed gases may be stored temporarily in the compressed gas storage vessel and thereafter used to power compressed air tools or other apparatus, or for other purposes requiring a source of compressed gases. Excess compressed gases not needed for other purposes may be used to drive the fly wheel and thereby keep it rotating for a maximum period of time. The apparatus does not require an outside souce of power once the fly wheel is rotating at a satisfactory speed and thus thereafter it may be transported to a desired site and used to compress gases without causing a pollution problem.
