UNITED STATES PATENT oFFicE,
ALLEN E. OS'IRANDER, 0F Il-IDGEWOOD, NEW JERSEY, ASSIGNOR TO AMERICAN CAR AND FOUNDRY COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
VALVE FOR TANK CARS.
Application filed May 17,
To all whom iii-may concern: Be it known that I, ALLEN E. OSTRANDER, residing at Ridgewood, county of Bergen, State of New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in a Valve for Tank Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to .which it appertains to make and to use the same, reference being had to the accompanying draw ings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described,
as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.
In said drawings:
Figure 1 is a "broken view, partly in section and partly in elevation, showing my improved discharge valve for tank cars; and
Figure 2 is a section taken on the line 2 2 of Fig. 1.
It is the object of my invention to provide an improved valve for the discharge outlets of tank cars of the type that is positively seated by a screw means that allows play between the valve and its seat sufiicient to permit of grinding the valve to its seat.
In the drawing,1 designates a car tank of which but portions are shown, having a bottom sheet 2, a top sheet 3 and a dome 4 secured to the top sheet 3.. I
Secured to the bottom sheet 2, by rivets 5, is a flanged discharge outlet casing 6 having the usual breakage groove 7 and screw threaded at the bottom to receive the usual cap, (not shown). The outlet casing 6'is provided at. its upper end with a valve seat 8 that faces into the tank and in the length of the casing 6 are the grooves 9, diametrically opposite tO-each other and extending for a short distance as shown in Fig. 1. In
order to providethe proper thickness of metal in the casing wall, the casing is ribbed throughout the length of the grooves, as at I 10 in Fig. 2.
Coacting with the seat 8 is a valve 11 provided with an upwardly extending collar 12 in which is secured, by the pin 13, a valve operating shaft 14: provided with a hand wheel 15 and guided by the bracket 16 secured to the tank dome 1. Projecting downwardly from the valve 11 are the guides 17 1920. Serial No. 381,946.
bar 21, the lower end of rod 19 is provided with a retaining collar 22 held in place by I the cotter pin 23. I
In use, operation of the hand wheel 15 causes the shaft 14 and valve 11 to rotate,
thus rotating the screw threaded rod 19.-
Rotation of the rod in one direction will cause the cross-bar 21 to be advanced along the rod 19 until it engages theupper ends ofthe grooves 9 and further rotation in the same direction, with the cross-bar 21 engaging theends of the grooves 9, will cause the valve 11 to be forced to its seat 8 with suifieient pressure to clear the seat 8 of much of the foreign matter that gathers there when the tanks are in service. Rotating the hand wheel in the opposite direction will cause the cross-bar 21 tobe advanced along the rod 19 towards the bottom of the grooves 9, freeing the valve 11 if it is seated. By rotating the hand wheel 15 until the crossbar 21 is away. from both ends of the gr o"oves, sufficient play is given so that the valve 11 may be lifted clear of the seat 8 and rotated so that different parts of the valve and seat will engage when the valve is replaced on its seat in the usual manner of'grinding a valve to its seat. Continued rotation of the hand wheel after the crossbar 21 engages the bottoms of the grooves 9 causes the valve 11 to be lifted from its seat and give a clear passage for the discharge of the contents of the tank.
. What I claim is:
1. In a tank car discharge valve, a discharge outlet casing having a valve seat and a plurality of grooves, a valve for said seat, operating means for said valve, means mounted in said grooves for reciprocatory motion therein and adapted to support said valve in the open positionthereof and a connection between said valve and said means adapted'to force said valve and said means into engagement wlth said casing.
