WILLIAM E. SN IPES, OF PINE BLUFF, ARKANSAS.
OSCILLATING VALVE FOR STEAM-ENGINES.
SPECIFICATION forming part of Letters Patent No.'245,669, dated August 16, 1881.
Application filed May 6, 1881.
To all whom it may concern.-
Be it known that 1, WILLIAM E. SNIPEs, of Pine Bluff, in the countyof Jefferson and State of Arkansas, have'invented certain new and useful Improvements in Oscillating Valves for Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being bad to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.
My invention relates to the valves of steamengines; and itconsists of oscillating valves adjusted on suitable seats on a steam-cylinder having the requisite induction and exhaust ports, so that the steam may be admitted directlyunder and through the valves at the top of the cylinder, and may escape at the bottom of the cylinder, thereby dispensing entirely with the ordinary steam chest, slide-valve, valve-rod, cylinder-cocks, and all the packingboxes, except the one for the piston-rod, and doing away with the great pressure on and friction of the slide-valve and keeping the cylinder free from water, which, with the present construction and arrangement of cylinders,
valves, and exhausts, often impedes the free action of the engine, and knocks out a cylinder-head. I
In the drawings, Figure l is a side elevation, without the valve, showing the valve-seat and steam-ports. Fig. 2 is an end elevation, showing the valve in place. Fig. 3 is a face view of the valve detached.
A is a cylinder provided on one side with the valve-seat B, having at the top the induction-port a and the leading-ports a, and at the bottom the leading-ports b b and the exhaustport b.
O is the induction-pipe at the top of the cylinder, and D is the exhaust-pipe under the cylinder.
E is the oscillating valve, provided on the face with the cups 0 d, and adjusted, when in place, on a shaft, F, attached to the side of the cylinder, and is held to the valve-seat perfectly steam-tight bya slight tightening of the (No model.)
jam-nuts f, the friction of this valve being very slight compared to the friction of a slidevalve. This valve is oscillated by power applied to the crank G.
In a cylinder ten by twenty inches the in duction and exhaust ports a b are two and V three-fourths inches wide at their outer ends, one and three eighths inch wide at their inner ends, and three and one-half inches long, and the leading-ports are one and five-eighths inch at their outer ends and one inch at their inner ends. The top of the cup cot the valve is about four inches, and the bottom of the cup dis about four and one half inches. The throw of the valve, measuring from the top of the steam-port, is two and one-eighth inches.
The improved oscillating valves are particularly adapted to the locomotive and other linkmotion engines, and, being always visible to the eye of the engineer, any defect in their working can be readily detected and remedied without the expense and trouble of taking off the chest-cover. The valves are protected from flying dust and grit'by a neat-fittingjacket of Russia iron, covering entirely the valves and seats.
hat 1 claim as new, and desire to secure by Letters Patent, is--- 1. An oscillating valve adjusted on a steamcylinder provided with a valve-seat having induction and leading ports at the top and exhaust and leading ports atthe bottom,whereby the steam is admitted directly under and through the valve and exhausted at the bottom of the cylinder, substantially as and for the purposes described.
i 2. The oscillating valve E, provided with the cups 0 d, and adjusted on a seat, B, on a steam-cylinder, having the steam-ports a a at the top and the steam-ports b b at the bottom, substantially as and forthe purposes described.
In testimony that I claim the foregoing as my own invention 1 affix my signature in presence of two witnesses.
\VILLIAM E. SNIPES.
