Description: |
| Abstract:
This invention relates to that class of air- engines in which, by the action of a piston, which may be termed the "exchange-piston," working in a cylinder, at or near one end of which is the working-piston and at the other end of which is the fire-place, the same air is over and over again transferred from each end of the said cylinder to the other alternately, being heated and expanded during its transference in one direction, and being cooled and contracted during its transference in the other direction, the said piston also performing the office of a regenerator.
Claim:
The combination, with the cylinder, crank-shaft, and crank of an air-engine, of a working-piston and an exchange-piston in the said cylinder, a beam and connecting-rod connecting the working-piston with the crank, and a bell-crank lever and connections connecting the crank with the exchange-piston. |
