UNITED STATES PATENT OEETQET JOHN TONGE, OF MINNEAPOLIS, MINNESOTA.
TH RoTTLEwALvE.
SPECIFICATION forming part of Letters Patent No. 397,672, dated February 12, 1889. Application filed January 5, 1.888. Serial No. 259,882. (No model.)
To aZZ whom it may concern:
Be it known that I, JOHN TONGE, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Improvement in Throttle-Valves, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure 1 is a longitudinal section of a valve embodying my improvement, and Fig. 2 is a detail side elevation of a valve detach ed from the casing.
Similar letters of reference indicate corresponding parts in both Views.
My invention consists in a valve formed of two parts connected together by an. adjustable connection.
The valve A is formed of two parts, a b, fitted to the valve-seats 0 cl. These valveseats in the present case are located in the globe-shell B in the usual way. The stem e of the valve 1) is made tubular and is externally threaded to receive the screwcap f and the jam-nut g. The valve (1 is provided with a stem, 72 having a flange, 1', upon the extremity thereof. The valve-stem It extends into the tubular stem e of the valve b, and between the flange of the stem 6 and the screw-cap f is placed a spiral spring, 7'. The tubular stem e is perforated near its juncture wit-h the valve 1) to allow steam to enter or escape, and thus allow the pressure within the tubular stem to become the same as that outside of the stem.
In the present case the valve a is provided with a stem, 1;, outside of the valve-seat c, which is jointed to a valve-rod, Z, extending through a gland, m, on one side of the globecasing B. tion that the valve 1) may strike its seat slightly in advance of the valve a, and each valve will therefore be seated independently of the other.
It will be seen by this construc- When my improved valve is applied to locomotives to be used as a throttle-valve, the globe-casing B is dispensed with, and the valve-rod Z is extended through the head of the boiler in the usual way.
One of the principal advantages claimed for my improvement is that when the valve is used as athrottle-valve on a locomotive the spring allows one-half of the valve to yield when the locomotive slide-valve is reversed, thus allowing the valve to act as a relief-valve for preventing the bursting of the steam-chest at the moment of the reversal of the link and valve and before the throttle-valve is opened to again admit steam to the engine-cylinder.
The boilern'essure will hold the valve I: closed, and the operating mechanism of the valve a will hold it closed against the b0ilerpressure.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the valve 1), provided with the tubular stem 6, of the screwcap f, the valve a, provided with the stem 72, and the spiral spring j, surrounding the tubular stem and compressed between the cap f and the flange 2 of the valve-stem, substan-- 'tially as described.
2. As an improved article of manufacture, a valve formed of the valve-casing B, provided with the valve-seats c (I, the'valve b, hav ing the perforated tubular stem 6, the screwcap f, fitted to the valve-stem e, the jam-nut g, the valve a, provided with the stem 71 having the flange 1', the spring interposed between the flange 11 and the screw-capf, and the rod Z, jointed to the valve-stem 7r, substantially as described.
JOHN TONGE.
