UNITED STATES PATENT OFF-ICE.
MATTHEW B. SELLERS, OF CARTER COUNTY, KENTUCKY.
ENGINE-VALVE.
SPECIFICATION forming' part of Letters Patent No. 608,4.83, dated August 2, 1898.
' Application filed June 14, 1897. Serial No. 640,790. (N 0 model.)
To all whom it may concern:
Be it known that I, MATTHEW B. SELLERS, a citizen of the United States, residing in the county of Carter, State of Kentucky, have ina diagram of the steam-passages into the cyl-' 'inder.
The valve, which is cylindrical and tapering, has two diagonal ports or ways 10 and q, Fig. 1, passing diametrically through it. By diagonal port is meant such a one 19, Fig. 1, that if its ends h and m were joined by a line this line would make an acute angle with the axis of the cylinder 0. This valve 0, Fig. 2, bya suitable gearing is caused to make one revolution for each double stroke of the piston. Starting with the piston at the end T of the cylinder B the valve-port 19 will connect the steam-chest R with the passage T, leading to the end T of the cylinder, while the port q will connect the exhaust-chest S with the passage V, leading to the end V of the cylinder. The piston will move toward V. At the end of the stroke the port 19 comes into register with the opening V, leading to V, and port q with they passage T, leading to the end T of the cylinder. Thus each end of the cylinder isconnected alternately with the supply and exhaust chambers, the duration of admission depending on the size of the openings 19, T, and V.
I amaware that prior to my invention engines have been made with cylindrical valves. I therefore do not claim the cylindrical engine-valve broadly; but
What I claim, and desire to patent, is
In a reciprocating engine, a cylindrical valve, with diagonal ports, passing diametrically through it; together with a Valve-casin g, having corresponding passages and steam and exhaust chests, so arranged, that the valve, by revolving, shall connect the ends of the cylinder, alternately, with the supply and exhaust chambers as herein described.
MATTHEW B. SELLERS.
