IMPROVEMENT IN VALVE-GEAR. 1
Specification forming part of Letters Patent No. 197,795, dated December 4, 1877; application filed September 10, 1877. I
To all whom it may concern Be it known that I, WILLIAM H. PIERCE, of Tolono, in the county of Ohampaign and State of Illinois, have invented a new and Improved Reciprocating Steam-Engine, of
which the following is a specification:
The invention will first be described in connection with the drawings, and then pointed out in the claim.
1n the annexed drawings, Figure 1 is a side elevation of the improved engine, portions of which are broken away to show the interior of the steam-cylinder. Fig. 2 is a plan view and a horizontal section through the pistoncylinder and valve-chest. Fig. 3 is a sectional view in detail of the hand'lever cut-ofl' and M the steam ports.
Similar letters of reference indicate corresponding parts.
The letter A designates the main or piston cylinder, and B the cylindrical steam-chest,
- in the well-known slide-valve engine, with wheel a by a cam-pin and with the pistonvalve.
A rod from the hub of the balance-wheel a connects with the upright arm K, having a handle, and also two pinsm n, arranged equidistant from the shaft N, which are used for reversing the engine. I
To the inner end of the shaft N is secured an upright arm, V, which is slotted longitudinally for receiving a slide, 6, that is movable by means of a screw and hand wheel, F. The connecting-rod S of the cut-off is pivoted .to the slide 0, so that by adjusting this slide the strokes of the pistons F F can be shortened or lengthened, and the cylinder A supplied with a greater or less amount of steam.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The combination, with a lever, K, having pins n n, and the shaft N and slotted arm V, of the adjusting devices 0 F, arranged as and for the purpose specified.
WILLIAM H. PIERCE.
