OUTLET VALVE Fon TANKcARs.

Application filed April 11, 1924. Serial No. 705,734.v j

To all 107mm t may concern.'

Be it known that I, STARLEY F. BEASLEY, a citizen of the United States, and resident of Kansas City, county of lVyandotte, and State of Kansas, have invented certain new and useful Improvements in Outlet Valves for Tank Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereo This invention relates to tank carsl and has for its principal objects to provide an outlet valve that will not be influenced by distortion of the tank or by vibration, or by the wash of the lading during travel; that will not be impaired by damage to the outlet tube; that will have no movable parts below the bottom sheet of the tank, and that will permit the expansion of freezing liquids in the outlet tube.

Further objects and advantages of the invention will become apparent as the disclosure proceeds and the description is read in connection with the accompanying drawings, in which` Fig. 1 is a fragmentary sectional view of a tank car equipped with a valve constructed and arranged according to this invention Fig. 2 is a side elevation of the valve; Fig. 3 is a vertical section taken on the line 3-3 of Fig. 4;

Fig. 4 is a plan View of the valve and a fragment of the bottom sheet of the tank, and

Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 3.

In the drawings indicates a sill of the car frame carrying the tank 11 having a dome 12 at the top adjacent to the middle. Below the dome the bottom sheet 13 is provided with an opening that communicates with an outlet tube 14, having a flange 15, secured to the bottom sheet by rivets 16. The valve controlling the outlet includes a cage having a base ring 17, uprights 18 on the base ring connected at their upper ends by a top ring 19 and surmounted by a cap or cover 2O bolted to the top ring. The base ring inside of the uprights is equipped with a fiat upwardly facing annular seat 21 which cooperates with the complemental portion at the bottom of a frusto-conical valve head 22. The cap has a boss 43 threaded to receive a valve stem 24, loosely swiveled at 25 to the valve head. Between Vthe valve head and the valve seat is an acid, oil and fireproof gasket 26.

`The'fthieaded stem 24 is loosely connected by a pin 34 with a forked operating rod 35 extending upwardly through la lguide 46 in the' dome'fand eqlipped with a hand wheel`27 atits upper enc.

The opening'in than the bore ofthe outlet tube 14 andV eX- tends back over the iiange 15, as indicated at 28. he base ring 17 extends within the opening in the bottomsheet and is welded thereto, as indicated at 29. The base ring 17, the uprights 18 and the top ring 19 are readily formed as a single casting, the uprights being composed of webs 36 and tapered lianges top ring. The flanges 37 cooperate with the heads 38 of the bolts 39 to whenv the nuts 40Yare being run down.V

The valve may be easily opened and se-l curely closed by turning the in the appropriate direction. the screw 24 extending the cage and the valve acts as a rigid strut holding the valve head securely against the seat. `The valve cage being relatively short and quite rigid is not affected by the distortion of the car, or the wash of the liquid,

When closed between the top of j etc., that impair the action of the valves now 1n service. v

Since no part of the valve projects below the bottom sheet into theV outlet tube, dam-` age to that tube whethercausing a severance at the breaking groove 30 or entirely dislodging the outlet tube, does not affect the func` tioning of the valve.

The seating of the valve head is not disturbed by pressure from below, but eXpansion due to freezing of liquids in the outlet tube is accommodated by air trapped in the pocket of the valve head.

37 connecting the base and prevent rotation I the bottom sheetis larger' hand wheel 27 The valve seat does not have to be ground or resurfaced and since the valve head is merely forced against the gasket 26 without any rotaryV motion the gasket will endure a long period of service.
