UNITED STATES PATENT OFFICE.
LEMUEL MAXFIELD, or MOLINE, ILLINOIS.
STEAM-CYLINDER COCK.
SPECIFICATION forming part of Letters Patent No. 253,405, dated February 7, 1882,
Application filed December 7, 1881. (No model.)
and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a side elevation of the cock applied to the cylinder of a steam-engine, partly broken away. Fig. 2 is a vertical section of the cock.
This invention relates to cocks which are especially designed for steam-engine cylinders, but which may be used for other purposes.
The nature of my invention will be fully understood from the following description and claims and the drawings hereto annexed.
The letter Adesignates the body of my improved cock, which is coustructed with two coinciding inlet-ways, a a, and a single outletway, b, arranged at right angles to the inletways.
B designates the stem or plug of the cock, which is slightly tapered and fitted into a corresponding bore made in the body A. This stem or plug is constructed with an upper extension, G, having aprismatic end to receive a key by which to turn the stem about its lougitudinal axis. The stem or plug B has L- shaped openings 9 9 through it, which are independent of each other-that is to say, they do not communicate with each other. The horizontal limbs of the openings or passages g g are so arranged that when they are in the position indicated in Fig. 2 they will exactly register with the horizontalpassages through the two ways out. When the cock-stem is turned one-quarter around the said horizontal limbs will be at right angles to the ways a a, and
' water will not pass through the cook. The
longest limbs or passages through the stem B are parallel to the longitudinal axis of this stem and discharge into the pipe D, which may lead to any desired point.
thereof through the cylinder-heads, and also communicating with the two ways a a of the cock, so that by turning the cock-stem water can be drawn simultaneously from both ends of the cylinder G and discharged through the drip-pipe D. When the steam-cylinder of the engine is very long I shall apply air-chambers L L to the two pipes J J to prevent that snapping noise and shock occasioned by the coudensing ot' the steam.
A cock thus constructed answers the purpose of two independent cooks for the purpose described, and itwill make no noise while using it. A single quarter-turn of the stem opens or closes both connections with the cylinder at the same time.
WVhat I claim as new is- 1. The combination, with the steam-cylinder, of the drip-pipes J J, the two-way cock constructed with independent passages, the drip or discharge pipe D, and the air-chain hers applied to pipesJ J, substantially as described.
2. The combination, in a steam -cylinder cock, of the body A, having fouhlimbs, the tapered plug B, fitted into two of these limbs, the independent L-shaped passages g g, and the spring 0, substantially as described.
3. The combination of the body A, the tapered plug B, fitted into the body, the independent L-shaped passages g gthrough the plug, the pipe D, and the pipes J, communicating with the ends ofthe steam-cylinder.
In testimony that I claim the foregoing as witnesses.
LEMUEL MAXFIELD.
