Description

A. VHITE, OF GENESEO, ILLINOIS.
GOVERNOR-VALVE FOR STEAM-ENGINES.
Specification of Letters Patent No. 32,934, dated July 30', 1861.
To all 'whom it may concern:
Be it known that I, A. VHITE, of Geneseo, in the county of Henry and State of Illinois, have invented a new and useful Improvement in Governor-Valves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specication, and to the letters of reference marked thereon.
The object of this invention is to arrange a valve for the governor of a steam engine that will be free from any unbalanced pressure of steam, and that therefore can be worked without the friction of an ordinary throttle valve; and it consists of a valve composed of two segments of a circle placed between two valve faces in the steam pipe, in such a manner that the steam passes the valve on both sides, and the pressure on either side is balanced by that on the other.
To enable others skilled in the art to make and use my invention I will proceed lto describe its construction and operation.
Figure l, of the drawing, is a section of a steam pipe containing my improved valve, and Fig. 2 is an end view of the same.
The valve chamber a cast in one piece with the flanged joint of steam pipe shown in the drawing, and it is composed of the transverse partition o, and the parallel partitions c, c, forming the valve seats, in such a manner that the steam entering the pipe at the end marked l, passes through the segmental openings in the partitions c, c, into the valve chamber o and out of the pipe at the end marked 2. The valve is formed of the two segmental pieces (l, al, that cover the valve faces on the partitions c, c, and are connected by the bars or braces c, c, and the center piece f, through which the valve stem g passes, and to which it is secured. The valve stem passes through a stuffing box in the exterior of the pipe, and is provided with a handle 71 by which it may be worked by the governor, or the engineer, as may be required to regulate the passage of the steam.
The valve is represented closed in the drawing; and as the handle is shifted in either direction the two openings shown in each of the partitions c, c, will be uncovered by the valve and admit the steam to the interior of the valve chamber o, whence it progresses through the pipe to the engine. The pressure of steam on each side of the valve is balanced by that on the other, and the valve may therefore be moved with but little power and without the friction consequent upon the pressure.
The valve I have described consists of two segmental pieces with an opening in each of them for the passage of the steam, but it is manifest that the two sides of the valve may be composed of circular pieces providedv
