TANK-OUTLET VALVE.'

Applicationled November 26, 1920. Serial No.j426,424.

vented a new and luseful Improvement iny Tank-Outlet Valves, of which the following is a specification. p

The present invention relates to tank car outletvalves and more particularly to such valves arranged in the bottom of the cartank and adapted to be operated by means located within the doine of the tank. It will be fully understood from the following description, illustrated by the accompanying' drawings, in which:

Fig.'1 -'s a partial longitudinal section through the tank, showing 'the mechanism for operating the valve in elevation; Fig. 2 is a broken sectional View through the valve and the operating mechanism therefor. y

`Fig. 3 is a detailview in elevation of the valve elevating lever;

Fig. 4 is a plan view of the same..

Fig. 5 is a detailV view Vof a cam member co-operating with the lifting valve; Y Fig. 6 is a horizontal sectional view on the line 6-6 of Fig. 2, and

Fig. 7 is a detail sectional View on line 7-7 of Fig. 2.

Referring more particularly to the drawings, the numeral 10 indicates the body of the car tank and numeral 11 thebottom of thetank proper. f ,Y p

The tank is surmounted' by a dome 12 in the usual manner. lIn the bottom- 11 of the tank an opening' 13 is provided. An outletf nozzle 14 having an enlarged upper portion `15 is secured tothe bottom of the tank in any suitable manner, for example, by riveting, its upper portion surrounding the opening 13. Within the upper portion 15 of the nozzle a casting 16 is secured to the bottom of the tank and likewise surrounds the opening 13. This casting is provided in its .upper portion with a threaded opening into which is screwed a suitable valve seat 17, preferably'of brass. Below the valve seat the casting 16 is provided with al spider 18- having a central opening through which the valve stem protrudes and which serves as a guide for the latter.

The valve 19 is preferably formed as an inverted conical frustrum and in closed position rests upon the valve Vseat 17, being y guided into its position by the downwardlyy protruding stein 20 which passes throughthe central opening in the spider`18. 4The guide v stem 2O is weakened as at 21, just below the spider, so that incase the tank car nozzle 14 .is torn away by accident, lthe end 'of the' valve steinl will V.break ofi' without unseating the valve and no protruding part will beleft below thespider 18'. The guide stem- 20 is preferably screwed into the'bottoin of the valve 19. A lead gasket 22 is provided,

upon which thevalve seat 17 is Sec'ui'ed'in v' order to make a'tight joint. l A The valve 19 is connected within the tank 10 by pin 23 to the r'od 24 which extends upwardly into the interior of the domev 12.

At an intermediate point a verticalslot25 f is formed in the rod 24 and spaced below ,it a 5 collar`26 is ixedto the rod. .A sleeve 27 is slidably mounted upon the rod 24, vand a pin 28 through its loyvere'nd passes through the slot 25 in rod 24. `Where the rod passes through ther top of the tank 1Q into the" dome 12 a vertical slot 29 isformedin ythe sleeve 27 and a lug 30 provided Ona plate 31 secured to the top of thetank projects `into' the slot 29 and prevents rotation of thev sleeve 27. Above the topof the tank 10 and' witliinthe dome 12the rod 24 and sleeve 27 pass through laniopeniiig in a bracket 32 se-v .To

cured to the side of. the dome 12. L the bracket is rotatably vsecured an internally Vthreaded hand wheel 33, the sleeve 27 being correspondingly threaded. Tothev top ofy the sleeve 27 is fixed a cam meinber34'pi'o vided with a projecting fin 35. To the .top

of the rod 24 is rotatably secured between washers 36 and 37 a cain 38 having"afiiffinv clined cam surface39 andan operating lever 40. y i In Figs. 1 and 2 ofthe drawings the de- `vice vis shown with the parts in their relative positions at a time when the rotation of the cam 38 will lift the valve 19 from its seat, the sleeve 27 being at its vhighest point relative to the :rod 24. With the parts in this position, rotation of the cam 38 causesthe cani surface 39 to ride upon the top of the n 35, thereby vertically lifting the rod 24 within the sleeve 27 and likewise lifting the valve 19 from itsjseat. In closing the valve from open position the cam 38 is returned to the position shown in Figs. 1 and 2, thereby permitting the rod 24 and the valve 19-to drop into their lowerno, Y i

to said bottoni externally ot the t;

most position with the valve 19 resting upon its seat, this action being aided by the coil spring el interposed between the bottom of the sleeve 27 and the collar 26. The hand wheel 33 is then rotated to effect downward movement ofthe sleeve 27, this effecting compression of the spring stl which tends to hold the valve 19 tightly upon its seat. At the saine time lthe cani tin 35 at the top of the sleeve 2T is lowered to a position so that there is no play upon it on rotation of the cain 38. Un reopening the valve the hand wheel 33 is rotated to raise the sleeve thereby loosening the tension upon spring all and bringing the cam into position for co-opei'ation with cani 3S, the valve being then readily opened by rotating the last named cam.

lAlthough the present invention has been described in connection with the details ot a specific forni of construction, it is not intended that these should be regarded as limitations upon the scope ot' the invention efreept in so lar included in the accompanying claims.

lVe claim:

l. In a car tank outlet, a car tank bottoni having' an outlet opening, a nozzle attached ik and surrounding the said opening, a castii cured externally to said bottom and within said nozzle, a valve seat threaded into said casting and supported thereby within the y outlet opening, the casting being provided "with a spider below the valve seat, the spider having a central opening, a reoiprocable valve adapted to seat upon the valve seat, and a guide stein secured to the valve and adapted to pass through the opening provided in the spider, said guide stem being weakened at a point just below the spider when the valve is seated.

2. ln a oar tank, an outlet secured to the bottom thereof, a reciprocable valve within the tank and adapted to close said outlet, a vertical rod secured to said valve, a sleeve surrounding said rod, means for reciprocating said sleeve relative to the rod, and coacting means on said sleeve' and rod tor raising the rod relative to the sleeve, said coacting means being inoperative when the sleeve is lowered relative to the rod.

3. In a car tank, an outlet secured to the bottom thereof, a reciprocable valve within the tank and adapted to close said outlet, a vertical rod secured to said valve, a sleeve surrounding said rod, a collar mounted on the rod below the sleeve, a coil spring sui'- rounding the rod between the sleeve and the collar, means for reciprocating said sleeve relative to the rod, said coil spring being compressed on lowering the sleeve and relaxing on raising it, and coacting means on spider below the valve seat, the spider hav-v ing a central opening, a reoiprocable valve adapted to seat upon the valve seat, a guide stem secuiedto the bottoni of the valve and protruding downwardly through the opening provided in the spider, said guide stein being weakened at a point just below the spider when the valve is seated, a rod se rnred to the valve and extending vertically upwards, sleeve surrounding said rod, aA

collar mounted on the rod below the sleeve, a coil spring surrounding the rod between the sleeve and the collar, means for reciproeating the sleeve relatively to the rod, said spring being compressed on lowering the sleeve and relaxing on raising it, and coacting means on said sleeve and rod for raising the rod relative to the sleeve, said co# acting means being inoperative when the sleeve is lowered relative to the rod.
