|mprovement in Reciprocating Steam-Engines.

IMPROVEMENT IN RECIPROC ATING STEAM-ENGlNES.
Specification forming part of Letters Patent No. 132,267, dated October 15, 1872.
To all whom it may concern:
' or less, as may be desired, thus being added.
The accompanying drawing is a longitudinal section of a stealncylinder provided with my improved piston.
.Similar letters of reference indicate correspondin g parts.
A is the cylinder. 13 B are the cylinderheads. 0 is the pistonrod. D is the conical piston. E E represent the steam -ports. In this example of my invention the piston is represented as a double convex, the sides F of the piston sloping from the piston-rod to the surface of the cylinder at an angle of about forty-five degrees, but I do not confine myself to any particular angle, nor to a convex steamsurface. The form of the piston shown-1nay be reversed, and the steam-surface of the piston may be concave, as the area of the piston may be increasedeither way. To make the clearance at the end of the cylinder as small as possible I make the cylinder-heads to correspond in form to the piston.
In applying my improved piston to old engines new cylinder-heads may be supplied, and the piston-rod may work through a stuffing-box in each head, as seen in the drawing, or through only one, as is usual.
By increasing the steam-surface of the piston in the manner described, it is claimed that the power is increased in the same proportion in any given engine with a given pressure of steam per square inch. This, I am aware, is not in accordance with theory or received opinions, but practice and experience sometimes upset theories and algebraical formularies, and I have found it so in this instance.
I do not confine myself to any particular form or style of piston, so long as the steamsurface or area is increased by making it conical, convex, or concave.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The cylinder-heads B B combined with piston D F, each constructed as and for purpose described.
