Definitions
- This invention relates to an improvementV in that class of steamcngines designed more particularly for use in rock drills, steamstamps, 85e., in which the piston itself forms the valve that-governs the admission and emission of the steam; and the invention consists in thepeculiar combinations and the construction and arrangement of parts, hereinafter more particularly describedand claimed.

WILLIAM S. SHARPNECK, OF DENVER, COLORADO.
STEAMmENGINE.
srncrr'rcATroN forming part @fretten-.Patent No. 367,119, dated July 26,1887.
l Application filed January 20, 1887. Serial No. 224,871. (No model.)
To @ZZ wwht t may concern:
Beit known that LWILLTAM S. SHARPNEOK, a citizen of the-United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and usefulImprovements in Steam-Engines, of which the following is a specication, reference being had therein to the accompanying drawings, in Which- Figure 1 represents a vertical sect-ion of a cylinder and piston constructed according to my improvement with the piston raised; Fig. 2, a similar view with the piston down, and Fig. 3 a section of the piston t-hrough the line x :v vin Fig. l.
- This invention relates to an improvementV in that class of steamcngines designed more particularly for use in rock drills, steamstamps, 85e., in which the piston itself forms the valve that-governs the admission and emission of the steam; and the invention consists in thepeculiar combinations and the construction and arrangement of parts, hereinafter more particularly describedand claimed.
Referring nowr to the details of`the'drawy At F are shown a number of openings drilled or otherwise formed in the shell or eX- tension,Which openingsare bored at an angle to the radial line, as shown in Fig. 3.`
On each side of the annular ports are packing-rings G to confine the steam to its proper place.
The operation is as follows: Supposing the piston to be in the position shown in Fig. 1, the apertures F in the upper half of the piston-shell are in communication with the upper steam-port, E, and thus steam is admitted to the upper half ofthe cylinder, which starts the piston downward with the whole force of the pressure in the boiler until the apertures F are out of line with the ports E, when the motion is continued by the expansion of the steam contained in the cylinder. As the apertures F pass down over the exhaust-port D the steam is exhausted from the upper part, and as the apertures F' (in the lower part of, the shell) come in communication with the inlet-port E the motion of the piston is reversed. As the steam passes through the aperturesFand F it acts on the inclined sides thereof and gives the piston apartial rotation at each stroke.
By this construction a veiy efcient and durable engine can be made at a very low cost, and one that will not be likely to get out of order. t
What I claim as new is- 1. The combinatiomwith the piston B, having annular extensions at its top and bottom and provided with apertures F and F,ofa cylinder, A, having the central exhaust port, D, the inlet-ports E E', and the heads @extending -within the annular extension of the piston,
substantially as described.
2. The combination of the cylinder A, having the central exhaust-port, D, inlet-ports E E', and packing-rings G, With'the piston B, having annular extensions at top and bottom Jrovided with steam-a ertures F F therein l P a and the heads @extending into the extension of the piston, substantially as described.v
In testimony whereof I affix mysignature,in presence of two witnesses,this 8th day ofJan# nary, 1887.
