,SPECIFICATION forming part of Letters Patent No. 642, 07, da d Jan ary 2 0- Application filed December 1, 1897. Serial No. 660,890. (No model.)
1'0 alt 10/1/0721, it may concern.-
Be it known that I, KENNETH RUsH'roN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Throttle-Valves, of which the following is a specification.
The object of my invention is to so construct a double-seated throttle-valve that it will take steam only from the top of the dome or other part of the boiler in which it is situated, thus preventing the admission of wet steam to the steam-supply pipe.
My invention is especially adapted to locomotive-boilers, and the valve is situated in the dome of the boiler; but it will be understood that it can be used in other types of boilers without departing from my invention.
In the accompanying drawings, Figure 1 is a sectional view of sufficient of a locomotiveboiler to illustrate my invention, the valve being open. Fig. 2 is a view' showing the valve closed.
A is the boiler.
A is the dome.
B is the steam-supply pipe, leading from the boiler to the cylinders of the locomotive in the present instance.
D is the valve-casing, secured to the steamsupply pipe 13 in any suitable manner.
E is the valve, having two flanges e 6, adapted to seats at cl at the top and bottom of the valve-casing, respectively. The valve has a central passage 6 open at the top and communicating with side passages 6 between the lower flange e and a disk 6 The disk e is adapted to the lower flanged portion d of the casing and is attached to the valve-rod E. When the valve is raised, as shown in Fig. 1, steam will be admitted to the valvecasing from the upper portion of the dome only, the steam passing between the upper flange c and its seat and down through the central passage 6 in the valve and out through the side passages 2 between the lower flange e and its seat, thus insuring the admission of dry steam to the supply-pipe B.- The valverod E is connected to a lever E pivoted at f to the pipe B, and is connected to an operating-rod E extending to the cab of the 1000- motive. When the valve is closed, as illustrated in Fig. 2, both flanges are seated on the casing and the disk is at its lowest point in the flanged portion d of the casing.
I claim as my invention- The combination of a valve-casing having two seats, a valve having upper and lower flanges adapted to said seats, said valve having a central opening, and a disk adapted to the valve-casing formed integral with the valve and arranged below the lower flange of the same, such location of the disk providing a passage between the same and the lower flange, with which the opening in the valve communicates so that steam will be admitted to the valve-casing only from above, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
KENNETH RUSHTON.
