INDICATOB. FOR TANK-CAR VALVES.
Application led June 29, 1921. Serial No. 481,876. l
Be it known that I, JOHN J. MCBRIDE,
residing at Bayonne, Hudson County, State `of New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in an Indicator for Tank-Car Valves, of which the follow-y ing is a full, clear, and exact description,
such as will enable others skilled in theart to which it appertains to make and to use the same, reference being. had to the accompanying drawings, which illustrate the preferred form `of the invention, though it is to be understood that the invention is not limited to the;l exact details of construction shown and described, as it is obvious that vvarious modifications thereof within the scope of the claims will occur to persons skilled in the art.`
applied to the valve operating mechanism.;
Fig. 2 is a section taken on `line 2-2 of.
Fig. 1; and
Fig. 3 is a view of my device shown detached'from the tank. 1 l
Itis the object of my invention to'provide an `improved l" indicator for the discharge valves of tank cars and it is also an object of'my invention to provide an 1nd1- cator that will insure the complete closing of the discharge valve by preventing the complete closing of the manhole cover until the discharge valve is completely closed.
A In theembodiment of my invention shown in the drawings, the tank is provided with the usual dome having a dome sheet 1, secured to the tank sheet 2 in any suitable manner and a dome head 3 having the usual .manhole opening closed by a manhole cover l erat-ing shaft 7 of the tank discharge valve (not shown). and serves -as an abutment for l the spring 8 mounted on the shaft 7 and confined between the bracket 6 and a collar 9 fixed on the shaft 7. A hand wheel 10 attached to the upper end of the shaft 7 serves as the operating means for the .shaft closed the hand wheel 10 will occupy the posltion shown ,in full lines in Fig. 1 Aand when the valve is com letely open the hand wheel l0 will occupy 51e position shown in dotted lines in Fi l.
Secured to the ome head 3 in any suitable manner, as by the rivets that attach the collar 5 to the dome head 3,'. is a bracket 11 1n which the rod 12 is slidably mounted, the bracket 11 being, as shown 1n Figs. 1 and 3, adapted to engage the rod 12 at a pluralityv of places s aced apart far enough to prevent the rod rom beingmoved from its normal upright position. The rod 12 is headedat both ends, the bracket 11 being so. positioned and the head u 13 so proportioned that when the rod 12 is raised thehead ,13' will lie in the path of the flange 14 of the manhole cover. The head 15 is shown larger than the head 13 but it need be only large enough to insure that it 'will lie in the path of the hand wheel 10 in all positions that the rod 12 'may assume inthe bracketfll.
Y With the manhole cover removed, operat- -.ing the hand wheel 10 will 'cause the rod 12 to be raised, projecting the head 13 into the manhole opening in a position such that the manhole cover cannot be replaced and, at the same time, indicatin that the discharge valve is not in its fully c osed position. Operating the hand wheel 10 to restore the discharge valve to the fully closed position will cause the rod 12 to be lowered, withdrawi the head 13 from the manhole opening, in icating that the valve isfully closed and permitting -the manhole cover to be completely closed.
What I claim is:
1. In a tank car, a rotary valve operating mechanism movable longitudinally and a. slidable position indicating mechanism for the valve projected into the manhole opening bythe longitudinal movement of said valve operating mechanism.
2. In a tank car, a longitudinally movable valve operating mechanism and a slidable position indicatin mechanism for the -valve operated by sai valve-operating means adapted. to prevent the closing of the manhole cover upon movement of said operating mechanism from closed positionn 3. In a tank car, a longitudinally movable and valve. When the valve is Acompletely valve operating mechanism comprising a hand wheel and means engaged b said hand wheel to prevent the closing of t e manhole cover.
4. In a tank car, a valve operating mechanism comprising a lon 'tudinally movable handwheel, a rod slidab y supported in the path'of the handwlieel and adapted to be projected by said handwheel into the path of the manhole cover.
5. In a tank car having a dome, a rotary valve operating mechanism movable longitudinally and a. slidable posltlon indicator for said valve mounted on said dome and adapted to be operated by the longltudinal movement of said valve operating mechanism.
6. In a tank car having a dome, a rotary discharge valve operating mechanism mov-- able longitudinally and slidable means carried by said dome and adapted to be operated by the longitudinal movement of said valve operating mechanism to prevent the closing of the manhole cover.
7. In a valved outlet equipment for tank cars, the combination of a. tank body with an outlet and an opening, the latter to be closed by a cover or closure element, a valve to control said outlet, a bracket fixed to tne body, a rod fixed to the valve and movable in said bracket, means for turnin said rod, and means slidable vertically Witi said rod Itoprevent placing of the cover or closure element in closed position until the valve is closed.
In witness whereof I have hereunto set my hand.
JOHN J. MCBRIDE.
