WiLLIAMJ. BRUNDRED. Improvement in Discharge Apparatus for Oil Tanks,
Grain Cars, &c.
015,115,317. Patented Junei3,1871.
Parana @rrroh WILLIAM J. BRUNDRED, OF OIL CITY, PENNSYLVANIA.
IMPROVEMENT IN DISCHARGE APPARATUS FOR OIL-TANKS. GRAIN-CARS. ho.
Specification forming'part of Letters Patent No; 115,817, dated June 13, 1871.
upon the discharging-stems of oil-tanks, as
hereinafter fully described and subsequently specified in the claim.
The accoinpanyingdrawing represents a sectional view of my discharge apparatus for oiltank ears, graiucars, 850.
Similar letters of reference indicate correspondhig part-s.
A A is a tubular casting secured to the upper shell of the tank or grain-car, with a screw or thread cut through a portion or the entire length of the hole, and through which the hollow stem B is designed to work.
B B B B is'a hollow stein, made of steam or gas pipe, of one or more sizesor diameters, and with a screw cuton' each end.
The screw or thread a on the top end of the stem B, and which works in the casting A, is of greater length than the screw B on the bot torn end of the stem, in order that the stem may continue to be raised after the thread or screw B on the bottom end of the stem has left the casting D at the bottom similar to A at the top, and until the holes E E E have been elevated to theheight of the castingD-or above.
teducers O (3 may he used to connect the different sizes of pipe used in making the stem B. E E E is aseries of holes cut in the bottom or lower end of the hollow stem B for the purpose of allowing the liquid or grain to pass out through the hollow stem B and the discharge or hole in the casting D, when the hollow stem is raised sufficiently to bring the holes above the top of the discharge-casting D, the discharge or escape of the liquid or grain being cut off when the hollow stem B is secured down into the thread or screw in the dischargecasting D. This arrangement of the hollow perforated and screw-threaded lower end of the tube B with the casting l) is employed in preference to the valves heretofore used, because it can be opened, although frozen up, by water lodging upon the inside of the tank when empty, which prevents the ppenin g of the valves.
Having thus described my invention, I claim as new and desire to secure by Letters Pat ent-- A stem, B, for oil-tanks, made hollow, and
threaded at a B to work in castings a 1),
when provided with a prolongation having the apertures E at the lower end, for the purpose of allowing the liquid to escape through the bottom of stem, but of retaining sticks and leaves.
Y V. J. BRUNDRED.
