STEAM-ENGINE.
SPECIFICATIONfom-ning part of Letters Patent No. 280,710, dated July 3, 1883.
- Application filed March 30, 1883. (No model.)
To all whom) it may concern Be it known that I, WILLIAM T. BAKER, -of Findlay, in the county of Hancock and State of Ohio, have invented certain new and useful 5 Improvements in Steam-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 being had to the accompanying drawings, which form a part of this specification,
and in which Figure 1 is a front view of my improved steam-engine. Fig. 2 'is a side view of the Fig. 3 is a vertical sectional view on line a: 00, Fig. 2. Fig. 4 is a similar View on line 1j 7/, Figs. 1 and 3. Fig. 5 is a sectional detail view of one of the shaft-bearings. Figs. 6 and7 are detail views of the piston-packing.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to rotary engines having an oscillating piston; and it consists in the detailed construction and combination of 2 5 parts of the same, as hereinafter more fully described and claimed.
In the accompanying drawings, the letter A indicates the cylinder, mounted upon a suitable base, and having an oscillating cylindrical 3o piston, B, provided with two diametrically-opposite wings, C, and mounted upon a shaft, D,
having an oscillating crank, E, upon one end,
which connects by a pitman or connectingrod,
F, with the wrist-pin G of a rotating crank or 3 5 disk, H, fastened upon the driveshaft I. The
inside of the cylinder has two sectorshaped recesses, J, diametrically opposite each other,
preferably at the upper and lower side of the cylinder,'and the two wings O of the piston 40 oscillate in these'recesses.
K is the live-steam pipe, which enters the top of the cylinder and divides into two livesteam channels, L, passing down the sides of the cylinder, one upon each side, and opening 4 5 about halfway down on the same into the two cylindrical valve-chambers M, from each of which two steam-channels, N and 0, open, leading to the upper and lower recesses of the cylinder, and from which the two exhaustchannels 1? open, carrying the exhaust-steam down into the hollow base, and from thence out through the exhaust-pipe Q. The two steam-channels form steam-ports R R in the inner side of each of the valve chamber, one above and one below the exhaustport S,while the live-steam channel forms a port, T, in the top of the chamber, in which an oscillating valve, U, rocks. This valve is Y-shaped in section, forming two wings,V, radiating from the shaft W, upon which it is fastened, and extending out to the inner surface of the valve chamber, and a shorter wing, X, having a longitudinal rectangular groove, Y, in which the square central portion of the valve-shaft \V fits. By this construction of the shaft and the valve it will be seen that the latter may be slid in from the end of the valve-chamber upon the shaft without requiring any further fastening, and the recess Z between the two wings is large enough to span one of the steam-ports and the exhaustp ort at the time connecting them, while the other steam-p ort and the live-steam port are connected, the steam passing around the back of the valve. The valve-shafts are provided at one end with cranks a, connected by a rod, 7),. hinged to their wrist-pins, and are adjusted in such a manner that as they'are operated simultaneously by suitable connection to an cecentric upon the drive-shaft, they will alternately admit steam upon the opposite sides of the wings of the piston, exhausting upon the other side, thus causing the piston to be oscillated and operating the engine.
To insure a perfectly steam-tight packing of the cylindrical portion of the piston the in- 8 5 side of the cylinder is longitudinally recessed or grooved at c, on each, side of the sectorshaped recesses, and packing-strips d are inserted in these grooves, bearing against the surface of the cylindrical piston, while the ends of the piston are packed by means of packing-rings e, inserted in annular grooves f in the heads of the cylinder,and forced against the ends of the piston by means of spiral springs g, secured in the heads of the cylinder 5 by means of caps 11, and bearing against the outside of the packingrings.
The wings C have recesses or groovesi in their tops and ends, and a number (three or more or less) of L-shaped strips, 9', are placed in these grooves, the horizontal parts of which strips are of unequal length, but placed in such a manner that the ends of the longer ones inserted fromone side meet the ends of the shorter strips inserted from the other side, as shown in the drawings, in such a manner that no twojoints fall in the same transverse line. These strips are pressed out against the sides and heads of the sector-shaped recesses by means of elliptic springs 7.,bearing against the bottoms of the recesses 1 and against the inner edges of the packing-strips, and by means of spiral springs I bearing against the vertical ends of the recesses and against the inner edges of the vertical ends of the L-shaped strips.
The piston-shaft is journaled in four bearings, I, one in each head of the cylinder and one on each side of the crank.
To insure a perfect eoncentrioity of the several bearings, I prefer to construct them in. the following manner, viz: m is the outer casing of the bearing, which is bored out conically withan annular recess or groove, a, into which the 0il-cup opens. 0 o are the boxes, made of any desired box metal, having inner concave cylindrical bearing-surfaces and outer conical. surfaces fitting into the conical bore otthe bearing.
The outer thicker ends of these boxes have annular grooves 12 near the ends, forming annula r flanges (1, which iit into an annular groove, 1-, in the inside of ascrew-thrcznled cylindrical. cap, 8, which fits into the outer screw-threaded end of the casingm, and serves, when the boxes become worn by use, to take up the wear, by screwing it farther in, pressing the boxes farther in, when they, by their cone shape, will be brought to bear tightly upon the shaft and .keep the bearings truly centered. The top of this cap is closed in thetwo end bearings,while in the bearings for the inner portion of the shaft the cap is open to admit of the shaft passing through the same. By having the annular groove or recess )1 encircling the boxes the latter may always be kept surrounded with oil, keeping it cool, while sufh'cient oil for lubrieating the shaft is admitted between the edges of the boxes.
A pump, a, of a construction similar to the engine, with the exception of the valves, may be placed above the engine and connected to the same by means of a connecting-1 ml, '0, hinged to a crank, w, upon the pistonshaft of the engine, and to a crank, 90, upon the piston-shaft of the pump, rocking the pump-piston. si1nultaneously with the engine-piston.
The operation of the engine will be readily understood by the foregoing description, taken in connection with the accompanying drawings, without further explanation.
Havingthus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination, in a steam-engine of the described class, of the cylinder having sectorshaped recesses, livesteain channel L, steamchannels N N and O O, and exhaust-channels P P, and the winged oscillating piston, with the cylindrical valvechambcrs M, having livestcain ports T, steam-ports R, and exhaust ports S, the valves U, having radial wings V, and longitudinal rectangular recesses Y in their shanks, the square valve-operating shafts \V, rocking in axial bearings in the valve-chambers, and. the means for rocking the same, as and for the purpose shown and set forth.
2. The combination, in a steam-engine of the described class, of the wings 0 upon the piston, having grooves in their tops and sides, and provided with the elliptic springs 7i: and spiral springs I, with the L-shaped packing-stripsj, placed with their inner ends overlapping each other, as described, as and for the purpose shown and set forth;
In testimony that I claim the foregoing as my own l: have hereunto affixed my signature in presence of two witnesses.
