PU PPET-VA LVE.
SPECIFICATION forming part of Letters Patent No. 299,006, dated May 20, 1884.
Application filed November 19, 1883. No model.)
1' 0 (0% whom it may concern:
Be it known that IJVILLIAM A. PENDRY, of Detroit, in the county of Wayne and State of Michigan, have invented: a new and useful Improvement in Puppet-Valves, of which the following is a specification.
The drawing is a vertical section through the steam-dome and valve, showing my invention as applied to the dry-pipe of a locomotive.
My invention consists in a modification of the valve for which Patent No. 282,766 was granted to me on the 7th of August, 1883, as hereinafter pointed out in the claims.
A represents the shell of the valve, made in such form as to be adapted for use as the throttle-valve of a locomotive. It will be readily understood that the shell must be made similar to that of an ordinary globe-valve when it is designed for use outside of a steamspace.
B represents the valve-seat, and O represents the valve, which is made long enough to extend through the valve-seat nearly to the opposite wall of the shell, the center portion being contracted and the ends enlarged, as shown.
L represents fair-leaders to guide the valve. The extended end of the valve is preferably made to fit loosely in a recess, M, in the shell,
but this is not absolutely essential.
D represents a rod projecting upward from valve G, carrying 011 its upper end a nut, F.
J represents a small valve which closes a steam-passage, N, in shell A, leading from the steam-space surrounding the valve-shell to a point opposite the extended end of valve 0, so that steam which passes through passage N will press against the extended end of valve 0.
I represents a rod projecting upward from valve J carrying on its end a nut, K.
G represents a rod answering the purpose of a valve-stem, moving in guides II on shell A, and operated by the throttle-lever through a bell-crank in the usual manner. To the upper end of rod G is attached an arm, E, in which are holes through which pass the rods 1) I. The nuts F K are so set that when rod G is forced upward, raising arm E, nut K will strike the top of arm E and raise valve J from its seat before nut F comes in contact with said arm, and consequently the main valve 0 I will first come to its seat when rod G is lowered.
0 represents a steam-dome in which the valve is placed.
The operation of my invention is as follows: \Vhen the engineer desires to open the throttlevalve, he forces rod G upward. This raises the small auxiliary valve J, and permits a current of steam to flow from the steam-dome through passage N and impinge against the extended end ofthe main valve 0, thus balancing said valve, so that when the continued motion of rod G brings arm E against nut F said valve will open easily. By changing the proportional end areas of the main valve 0 it may be balanced to any desired extent, as will be obvious to any mechanic. hen rod G is lowered, the main valve 0 comes to its seat while passage N is still open and a current of steam passing therethrough. This causes said main valve to close noiselessly without any shock. 1
If designed for use as a globe-valve,the rods D I should be attached to the valve stem substantially as they are to .arm E, and the shell should be made like those now in use, plus the passage N and recess M.
'What I claim as my invention, and desire to secure by Letters Patent, is
1. In combination with a main valve which extends through its seat to a point near the opposite wall oi' the shell, a steam-passage in the shell extending from the steam side of the valve to a point opposite the extended end thereof, and a small auxiliary valve adapted to close said stea1n-passage, both the main and auxiliary valves being so connected with a valve-stem that the auxiliary valve will open before and close after the main valve, substantially as shown and described.
2. The combination of the valve-seat B, valve C,extending through its seat and terminating in the recess M in the opposite wall of the shell, steam-passage N, and valve J, said valves 0 and J being so connected with a valve-stem that the motion thereof will open valve J before opening valve 0, substantially as shown and described.
