UNITED STATES PATENT OFFICE.
JAMES W. PLIMPTON, OF OIL CITY, PENNSYLVANIA, ASSIGNOR TO MICHAEL GEARY, OF SAME PLACE.
d STEAM-ENGINE..
SPECIFICATION forming part of Letters Patent No. 258,866, dated May 30, v1882.
Application led April 1, 1882. (No model.)
To all whom it lmay concern:
Be it known'that I, JAMES W. PLIMPTON, a citizen oi' the United States, and a resident of Oil City, in the county of Venango and State of Pennsylvania, have invented new anduseful Improvements in Steam -Engnes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings and 1o the letters or ti gures of reference marked there- This vinvention relates to the construction of steam-engine. cylinders; and it consists in the arrangementot the various chambers,ports, I5 and other parts, in the manner hereinafter described, and formed within one piece of metal. The invention does not consist in forming all the essential parts in one lpiece et metal, for this has been practiced for a great many 2o years, and has long been well known in the art, but the invention consists in the relative position given said parts in such a piece of metal.
My device is shown in the accompanying 2 5 drawings as follows:
Figure 1 is a vertical longitudinal section on the line g/g/in Fig. 2,loolingto the right. Fig. 2 is a vertical transverse section on the line fr a: in Fig. l. A
The parts are as follows: A is the cylinder'- body; A', the piston-chamber. B is the steamchest; B', the valve-chamber. C is the livesteam entrance or supply passage, which runs from the top of the cylinder down one side of it, and at the bottom branches into longitudinal passages c c, which run to the ends of the steam-chest, where are chambers b b, with which they communicate. D is the pedestal or base of the cylinder. D' is acavity or hollow space 4o cored ont ot' the base for the purpose of sav- E is the exhaust-passage. All the ing metal.
The caps F and G and the heater-chamber H are separate pieces bolted to the aforesaid casting.
The steam-chest as shown is intended to receive a piston-valve which takes steam at the ends and exhausts in the middle. a, a are the ports of the cylinder. They are located in the usual manner and communicate with the 5o valve-chamber. They are formed in the casting as it is made by cores. They thoroughly drain the piston-chamber ot any condensation which may occur, and the exhaust port or passage E is so placed as to in turn drain the valve-chamber, and thereby perfect drainagel of the whole device is fully provided for.
What I claim as new is- A casting for a steam-engine having a cylinder, A, with piston-chamber A', a pedestal, 6o D, for supporting the same, a steam-chest, B, with valve-chamber B', lying below and parallel with said cylinder and within said pedestal, and connected to said piston-chamber by ports a a, and being sufficiently shorter than said cylinder to leave spaces b b at its ends, an exhaust passage, E, leading from said valvechamher directly through the walls ot' the pedestal, and, iinally, a supply-passage, C, which passes from above the cylinder to below the 7o steam-chest, and there branching into passages c c, leading to the spaces bb, all of which parts .are produced iu said casting at the operation of casting. v
In testimony that I claim the foregoing I have hereunto set my hand this2istdayofJannary, 1882.
