' IMPROVEMENT IN RECIPROCATINGSTEAM-ENGINES.
Specification forming part of Letters Patent No. 133,513, dated December 10, 1872.
To all whom it may concern:
Be it known that I, SILAs TORREY, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Steam -En gines, of which the 7 following is a specification:
short steam-passages between the steam-chest and cylinder; to which ends the improvement 7 consists in interposing between the cylinder and the steam-chest in which the slide-valve works an intermediate steam-chest having extra ports at each end corresponding with the usual ports of the cylinder, and provided with proper valves and reversin ggear, as hereinafter more fully specified.
In the accompanying drawing, which represents my improvements as embodied in the best form now known to me, Figure l represents a side elevation of so much of an engine embracingmy improvements as is necessary to illustrate the subject-matter claimed; Fig. 2 represents a vertical longitudinal central section through the cylinder and steam-chests with the parts in the relation they assume when the engine is going ahead; Fig. 3 represents a vertical longitudinal section throughthe exhaust-ports on the line as m of Fig. 6; Fig. d represents a transverse section through the valve-chests and cylinder in the axial line of one of the reversing-valves; Fig. 5 represents a vertical section through the exhaustpipe; Fig. 6 represents apl an view of the 7 double set of ports, 6 e a, at each end,
either set being capable of being connected with the passages d d, as hereinafter explained. The valves D D are operated by means of a hand-lever, F, and two interlockin g sectorgears D D each gear being mounted on the arbor of its respective valve. Stops ff limit the movement of thevalves. A valve, G, slides on top of the chest E over the ports e e e a its throw being regulated by the valve rod g and its connections, as usual.
In operation, steam enters the slide-valve chest H through the induction-pipe I, and (with the parts in the relation shown in Figs. 1 to 6 inclusive) passes down the passages e", ,d, and b to the cylinder, as shown by the arrows in Fig. 2. The other ports are covered by the slide-valve. The steam, escaping from that end of the cylinder toward which the pis ton-head is moving, passes up through the passages 12, d, e, g and j to the exhaust-pipe J. The details of these parts are clearly shown in the drawing, and, being well known to skillful engine-builders, need not be here described. 0n the reverse stroke of the engine, the slide-valve moves far enough to clear the port 0 and to cover the port c with the exit-port g, the valves D D remaining stationary; the steam then enters through the valve D and escapes through the valve D these motions being repeated at every reciprocation of the piston-head. To reverse the motion of the engine, the engineer, without disturbing the slide valve, rocks the faucetvalves D D in their bearings, by means of the handlever F, until the parts assume the attitude shown in Fig. 8. This movement closes the ports 0 c and opens those 0 6. The steam now passes to the cylinderthrough the ports 0 d, and 1), until thestroke is completed, the escaping steam passing through the ports b, (1, e and 9 On the reversal of the stroke the slide-valve opens the port 6 and covers that e, and exhausts the full end of the cylin der, as above explained.
I am thus, by my invention, enabled materially to diminish the length of the steam-passages, and consequently the amount of steam wasted, by using two short steam-passages between each set of the slide and faucet valves, and a single direct connection between each of the faucet-valves and the cylinder, instead slide-valve, and the double set of ports connectin g the slide and reversing valves, these m embers being constructed and arranged to operate substantially as set forth.
In testimony whereof I have hereunto subscribed my name.
- SILAS TORREY.
