VALVE-=G EAR.
SPECIFICATION forming part of Letters Patent No. 344,027, dated June 22, 1886.
Application filed February 23, 1886. Serial No. 192,801.
To aZZ whom it may concern:
Be it known that I, CHARLES Honnon BEN- TON, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Valve-Gear, of which the following is a specification.
My invention relates to an improvement in valve-gear in steam and other engines in which the supply-ports accompany the piston in its reciprocating motion, and is especially adapted to single-acting engines. Heretofore the valves of such engines have been moved by tappets situated in the piston-head or in the cylinder-head, or by the angular motion of the connectingrod. Such means do not allow of variation of the rapidity of the valve motion relatively to the piston motion.
My improvement has for its object to provide a valve-gear which,while it has the necessary compound motion, can by change in the relation or dimension of its relative parts produce any desired distribution of the motive fluid; and it consists of a lever mounted on and moved by the crank-wrist and connected by one link to the valve-stem, and by a sec- No model.)
ing-rod and the nearer bend of the crank-wrist are not shown.
1 is one part of the double connecting-rod.
2 is a link which joins the valve-stem to the oscillating bell-crank lever 3. The bell-crank lever is made in two parts, 3 and 3, for convenience of placing and adjusting upon the crank-wrist 4L.
5 is a second link, one end of which is joined to the arm of the bell-crank lever, and the other end joined to a pair of cars, 6, upon the engine-frame 7. As the crank-shaft revolves, this link causes the arm 3 of the bellcrank lever to oscillate about the crank-wrist 4, thus'giving a proper reciprocating motion through the link to the valvestem.
NVhat I claim, and wish to secure by Letters Patent, is-
1. The combination, in a valvegear, of a crank-wrist, a lever moved thereby, and two I links connected to said lever, one of which gives motion to the valves, and the other causes the lever to vibrate relatively ,to the crank-wrist, substantially as and for the purpose set forth.
2. The combination, in a valvegear, of a crank-wrist, a bell-crank lever, 3 and 3, a link, 2, giving motion to the valves, and a link, 5, joined to the engine-frame, substantially as and for the purpose set forth.
CHARLES HORACE BENTON.
