Application filed February 1'7, 1916. Serial No. 78,901.

To aZZ whom it may concern:

Be it known that I, VILLIAM E. WooDARD, of Schenectady, in the county of Schenectady and State of New York, have invented a certain new and useful Improvement in Tender-Tank Valves, of which improvement the following is a specification.-

My invention relates to valves for controlling the supply of water from the tank of a locomotive tender to the injector connections on the locomotive, and its object is to provide an appliance of such type which will be desirably applicable in connection with the water bottom tender tanks which are now in general service, and which will obviate the necessity of perforating the upper sheets of the water bottom and extending the operating shaft through the coal space of the tender.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawing: Figure l is a side view, in elevation, of a locomotive tender tank, showing an application of my invention; Fig. 2, a side view, partly in ele- Vation and partly in section, of an appliance embodying my invention; Fig. 3, a plan or top view of the same; Fig. at, a vertical longitudinal central section, taken in a plane at a right angle to that of Fig. 2; and, Fig. 5, a vertical longitudinal central section, taken in the plane of Fig. 2, and on an en larged scale, through the valve proper.

In the practice of my invention, I provide a valve casing comprising three connected cylindrical sections, viz: an upper cupshaped receiving section, 1, which is open at its top to the water space of the tender tank, A, and forms a well which incloses the valve; an intermediatersection, 2, which is open at both ends, and fits in the lower end of the section, 1; and a lower strainer or delivery section, 3, which, in turn, fits in the lower end of the section, 2, and is closed at the bottom by a removable cap, 3 secured in position by studs, 3 A valve seat, 2 is formed at the top of the intermediate section, 2, and a valve guide cage, 2 is formed integral with the section, above and concentric with the valve seat.

A horizontal crank shaft, l, having an operating arm, 4?, fixed on its outer end, is journa-led in the intermediate section, 2, and extends through a properly packed stuffing box, 2, thereon. The crank, 4 of said the locomotive, is connected shaft, is coupled, by a connecting rod, 5, to a pin, 6", fixed in a valve, 6, which is of the puppet type, and controls communication between the tank, A, and the casing sections, 2 and 3, by being raised and lowered from and to the valve seat, 2*, by the oscillat1on of the crank shaft, d, by the operator. It will be obvious that an eccentric would be the mechanical equivalent of the crank, and would be similarly operative if substituted therefor. A limited degree of relative movement of the valve and connecting rod is provided, by making the upper eye of the connecting rod of larger diameter than the pin, 6 of the valve, as shown in Fig. 5, the object of this provision being to permit the valve to lift slightly from its seat, in the event of being subjected to pres sure by steam blowing back through the hose connecting the valve casing with the locomotive, when admitted for heating the water in the tank.

A cylindrical strainer, T, is fitted delivery section, 3,0f the valve casing, and 1s nsertible and removable by detaching the cap, 3, thereof. A delivery pipe, which is ordinarily in the form of a hose section, 8, leading to one of the injector connections of to one side of the casing section, 3,. with which it communicates through a delivery opening in the wall thereof. The casing sections are connected by bolts, 9, having nuts, 9 on their lower ends, and the upper casing section is secured to the bottom of the tender tank, by bolts passing through holes, l in a circumferential flange, 1*, formed on its upper end.

As shown in Fig. 1, the appliance is readily attachable to the bottom of the tender tank, in position where it is conveniently accessible to the fireman, and is entirely clear of the coal space of the tender. Access to the interiorv of thecasing, for renewal or repair of the working parts may be had whenever required, by detaching the intermediate and delivery sections.

I claim as my invention and desire to secure by Letters Patent:

A valve casing of the class described, comprising a cup-shaped receiving section, having means for attaching it to the underside of a tank and an opening in its bottom, a cylindrical intermediate section, open at both ends, having a valve seat formed in its top, which projects into the opening in said cup-shaped member, and having valve guides projecting upwardly from around said valve seat, and a cylindrical strainer or delivery section, fitted against the lower end of said intermediate section and having a lateral outlet, bolts clamping said three sections together, a cap closing the lower end of said strainer or delivery section, a valve mounted in said guides, a crank-shaft journaled in the Walls of said intermediate section and connected to said valve, and man ually operable means on the end of said crank shaft.
