OSCILLATING ENGINE.
SPECIFICATION forming para; of Letters Patent No. 294,219, datedrebrury 26, i884.
Application filed September 4, 1883. (No model.)
'ITO all w/tom may concern: l
Be it known that I, JOHN O. GILBERT, a citizen of the United States,.and a resident of Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Oscillating Engines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification, and in which'- Figure l is a vertical sectional view of my improved oscillating en gine,taken through the shaft. Fig. 2 is a similar view at right angles to Fig. l, and Fig. 3 is a horizontal section of'` the same through the trunnions and the feed and exhaust pipes.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to oscillating steam-engines; and it consists in the improved construction and combination of parts of such an engine, in which the steam is fed into the steam-chest from the feed-pipe, which is conl centric with the trunnions, through a curved' pipe turning in a stuffing-box at the end of the feed-pipe and entering the steam-chest upon the side of the cylinder, and in which the steam is exhausted through a similar pipe into an exhaust-pipe concentric with the other trunnion, as hereinafter more fully described In oscillating engines in which the steam passes through tubular trunnions, the latter must necessarily be of a larger diameter than solid trunnions, which increases the friction-v surface largely, the hollowing out of the trunnions weakening the same considerably,which necessitatestheirbeingmadeofacomparatively large diameter; and to obviate this inconvenience and give the cylinder a solid support I construct my engine, aswillnow be described.
In the accompanying drawings, the letters A A indicate supports, which form bearings or boxes B B at their upper ends, in which the trunnions C C of the cylinder D are journale'd or rock. The cylinder is of the usual construction, forming a valve-chest, E, which is preferably cylindrical at one side, and forming an exhaust-channel, F, around its middle opening at a point diametrically opposite to thevalve-chest.
G is the piston. H is the piston-rod, and I the shaft having a crank, J, to which the crosshead Kof thepiston-rodis hinged. Aslightly wedge-shaped valve, L, rocks in the cylindrical valve-chest, distributing the steam from the live-steam pipe around the valve into the cylinder through two steam-channels, M, opening` inthe steam-chest, the exhaust-steam passing through a port, N, between the steamports into the exhaust-channel.
O is the feed-pipe, which is provided with a governor, I), of the usual construction, and with a stuftihgbox, Q, at its end which is opposite to and'concentric with one of the trunnions, the said stuffingbox being supported by a bracket, It, extending from one of the supports, or by any other suitable means. A curved live-steam pipe, S, opening at one end into the valve;chest, fits and rocks with its other end into the stuflng-box upon the end of the feed-pipe, and` is provided with a cap, T, which closes the stufing-box and makes the joint perfectly tight, being heldin place by bolts U or similar means. The curved portion vV of the exhaust-pipe XV opens at one end into the exhaust-channel diametrically opend into a stufngbox, X, supported by a bracket, Y, and fastened upon the end of the exhaust-pipe proper, Z, which end is opposite to and concentric with the other trunnion of the engine, forming a steam-tight j oint, similar to the joint upon the steam-pipe. It will thus be seen that the cylinder will be supported and rocked upon its solid trunnions, and the steam fed and exhausted through the curved rocking live-steam and exhaust pipes being distributed by the valve, which may be operated by an eccentric disk and rod, or by any other suitable Ineans.
Having thus described my invention, I claim and desire to secure by'Letters Patent of the United States` l. An oscillating steam-engine having its trunnions solid, and having a curved liveposite to the valve-chest, and fits with its other- IOO 2 enligne posite sides of the cylinder :it one end, and l portion of its exhaust-pipe opening into the opening at their other ends into stuiiing-boxes upon the ends of the feed and exhaust pipes rocking in the sume, the said boxes being opposite to und concentric with the trunnions7 as und for the purpose shown and set forth.
2. An oscillating vengine having :i Curved live-steun] pipe opening into the valve-chest upon the side of the Cylinder, and having the other end of the said pipe turning in 2t stuffingbox opposite to und oonoentrio with one of the trunnions ofthe cylinder and fastened upon the end of the feed-pipe, as and Vfor the purpose shown and set forth.
3. An oscillating engine having u Curved exhaust-channel upon the side of the cylinder, and having its other end fitting and rocking into ai Stuffing-box upon the end of the eX- huustpipe opposite to und oonoentro with zt trunnion of the Cylinder, as und `for the purpose shown and set forth.
In testimony that I'olztini the foregoing as my own I have hereunto afxed my signature in presence of two Witnesses.
