Abstract
A mechanical pneumatic piston is comprised of an upper cylindrical section and a lower cylindrical section, wherein each section has four linearly elongated, miter-cut staves, an end sleeve, and a slide-guide ring. The mechanical pneumatic piston is further defined as having an internal upper, central, and lower cavity adjacently aligned and extending axially within the piston.
Claims6
A linearly reciprocating piston apparatus comprising:
- a first piston shaft formed of a first end plate having a plurality of perpendicularly attached, downwardly extending, linearly elongated upper stave extensions;
- a second piston shaft linearly aligned along its vertical centerline with said first piston shaft, said second piston shaft formed of a second end plate having plurality of perpendicularly attached, downwardly extending, linearly elongated lower stave extensions;
- a first blocking plate connecting lower ends of said upper staves while providing a pattern of passage notches for interfitting with the aligned and passing lower staves;
- a second blocking plate connecting upper ends of said lower staves while providing a pattern of passage notches for interfitting with the aligned and passing upper staves;
- a first end cap fitting over said first end plate and circumscribing the upper end of said upper stave extensions;
- a second end cap fitting over said second end plate and circumscribing the lower end of the lower stave extensions;
- and
- wherein the number of upper stave extensions matched the number of the lower stave extensions, said upper stave extension and lower stave extensions being spaced such as to allow alternate passage of an upper stave between two lower staves and a lower stave between two upper staves.
