Description

UNITED STATES PATENT OEEICE.

vETHAN A. GATES, OF BURLINGAME, KANSAS, ASSIGNOR OF ONE-HALF HIS RIGHT TO SANFORD R. LEONARD.

IMPROVEMENT IN THROTTLE-VALVES.

Specification forming part of Letters Patent No. 154,661. dated September 1, 187i application filed January 24, 1874.l v

To all 'whom it may concern:

Be it known that I, ETEAN A. GATES, of Burlingame, in the county of Osage and State of Kansas, have invented a new and useful Improvement in Throttle-Valves, of which the following is a specication:

The invention will first be fully described, and then pointed out in the claims.

In vthe accompanying drawing, Figure 1 represents a Vertical longitudinal section of the entire device on the line .r x of Fig. 2. Fig. 2 is an elevation, showing the throttlevalve as when in use. Fig. 3 is a cross-section of Fig. 1, taken on the line y y.

Similar letters of reference indicate corresponding parts.

A is the valve-shell. B represents the valve. G is the valve-rod. I) is a packin g-rin g around the valve. This packing is an elastic ring out longitudinally, and confined between the shoulder E of the valve and below the nut F at the top, and is made to snugly nt the valve-cylinl sides of the valve marked K in the drawing.

L is the valveseat. When the valve is on its seat these ports are closed, and when the valve is raised the steam passes through 'the ports K into the chamber J, and is discharged into the steam-pipe attached to the shell at the point M. N is the top ofthe Valvechalnber, which is screwed into the top of the shell. O is a stuffing-box therein. l is the lever, by means of which the valve is operated. Q is an oil-tube, which passes down through the shell, and delivers oil to lubricate the valve. This valve is balanced by the pressure of steam upon its sides, so that it works up and down without Vundue friction, and always works steam-tight. The positions of the ports K vare indicated in the cross-section.

Having thus described my invention,I olai 1n as new and desire to secure by Letters Patent- 1. A piston throttle-valve, having a chambered shell, J, and ports K, and provided with an oil-tube, Q, for lubricating the valve, substantially as shown and described.

2. The interior rod H and Wedge G, in combination with the expansible packing-ring D, as shown and described, and for the purposes set forth.

ETHAN A. GATES.
