Abstract:
This invention is intended as as an improvement upon the patent granted to myself by the United States Patent Office, dated ,April 5, 1870,'No. 101,617, for an "Improvement in Direct-Action Compound Steam- Engines," the improvement referring exclusively to the mode of operating the steam-valves when it is desired to work the engines singly, and not in pairs, as set forth in the patent above referred to, the same being directly applicable to the construction of single direct-action engines, as commonly employed for pumping purposes, which engines, invariably take full-pressure Steam throughout the entire stroke, a consequence attendant upon the general means employed to operate the steam-valve, which is alternately reversed by a motion communicated from the steam-piston or its rod, at or about, the termination of each stroke, in a variety of ways, each the subject of air individual patent.
Claim:
In a compound engine, as described, where the opposite faces of each piston presents an unequal area, the arrangement of the passages R R', eduction-ports J J', and steam-passages Q Q', or their equivalents, in combination with the main pistons E E' and valve-pistons N N', in such manner that the live steam, upon the completion of each stroke, will pass directly from the annular cylinders to the vmain-pistons N, by the passages R and Q, for the purpose of operating the valves, as described., The slide-valves, admitting the impelling agent employed to the valve pistons, which, in turn, and at the proper time, become valves for controlling the action of the slide-valve pistons, the one admitting the impelling agent to the other alternately. |
