Application filed May 31,1904. Serial No. 210,4021
T 0 all whom it may concern:
Be it known that 1, CHARLES A. LIND- sTRoM, of Allegheny, Allegheny county, Pennsylvania, have invented a new and useful Tank-Valve, of which the following is a forming part of this specification, in which- Figure- 1' is a vertical central section of a valve constructed in accordance with my invention; Fig. 2 is a horizontal section on the line IIII of Fig. 1; Fig. 8 is asectional plan .view on the line III-III of Fig. 1 illustrating the preferred manner of connecting view of the valve-stem; Fig. 5 is a partial vertical section and side elevation of a tank for tank-cars fitted with my valve; and Figs. 6 and 7 are respectively a plan and side view of themeans for lifting the valve-stem.
The purpose of my invention is to improve the construction of tank-valves such as used for tank-cars in order to make it possible to empty the entire contents of the car when desired, and to provide for the partial discharge A valve constructed in accordance with my invention possesses advantages over those heretofore used in respect of a simple and cheaper construction and a better provision against leaks.
In the drawing 2 represents the valvecasing or housing which is riveted or otherwise secured as at 3 to the bottom of the tank 4, and has at its upper end a seat 5 for the valve 6 which is swiveled on vertical stem 7. This stem preferably fits in a.- socket 8 at the top of the valve, and has a peripheral groove 9, enabling it to be connected with the socket by a U-shaped cotter 10, which is inserted in shown in Figs. 1 and 3. The valve 6 is preferably formed with radial wings 6 between which 1s a removable set screw 11 which protween two of the wings and thus enables the valve to move vertically ,but limits its turning motion; The valve has adownwardly projecting sleeve 12 having a threaded por tion at its lower end in whichiitsth'e threaded stem 13 of a cap 14 which is adapted to fit within he lower end of the casing 2 and has a thing: 1} bearing against a gasket or packing ring it at the end of the casing. The cap has a squared portion 17 for the application 1 of a'wrench by which it may be turned, and
when so turned the stem 13 can be screwed into the sleeve -12, and the cap 14 thus brought towards of drawing the valve. to its seat 5 and of seating the cap against the gasket 16, thus close ing the casing at both ends.
When it is desired to open the valve to permit the partial discharge of the contents of the tank, the cap llmay be turned so as to unscrew its stein partially from the socket,
the valve 6, with the effect thus freeing the valve 6, which can then be raised and lowered vertically by means of its stem 7. By removing the cap 14 the valve 6 can be raised to cause the entire discharge of the contents of the tank.
A part of my present invention consists in making the stem 13 a part of the cap 14, and the threaded sleeve 1.2 a part of the valve 6. This affords a cheaper and stronger construction than if the stem were part of'the valve and were screw-threaded into the cap, for the housing 2 must be of considerable length in order to extend below the center sills of the car to which it is applied, and as the valve proper is frequently made ofbrass, while the cap is made of gray or malleable iron, I effect 1 enables me to lift the valve either with a di- 'rect vertical motion or by a vertical motion produced by rotation of the stem as desired.
I prefer to employ the lifting device shown in Figs. ,5, 6 and 7 in which the stem at its upper end has a handle 18 within the tank which bears upon an inclined are .19 forming part of a supporting bracket 20. By rotat ing the handle 15 along the arc in the direction of the arrow in Fig. 6 the stem and valve are raised after the cap has been loosened or removed from the valve. At the end of the inclined are 19 is a recess and retaining notch 21 for retaining the handle at the end of its motion, thus keeping the valve open. The swiveled connection of the stem with the socket is also of advantage because it enables the vaive to be rotated by the cap 14' within the limits of the loose motion afforded by the stop or setscrew 11. I
I claim:
1, In a discharge valve for tank cars, the
combination with a tubular casing having a .tosaidcasing and formed with internal screw-threading in its lower end and a. 'lor the lower cap end of said casing having an elongated stein threaded to fit the of said valve. 2. In a discharge valve for tank ears, the combination with a tnhulai' easing,- having a valve seat a t one end, a valve heated in said casing shaped to lit said seat, short relatively to said casing and formed with internal screw-t]neading in its lower end, and a cap for the lower end of said casing havin a tapered elongated stein lower end of said valve.
3. In a discharge valve for tank cars, a tubular casing, relatively thereto and having narrow elongated radial wings, a set screw in said casing projecting into a space between a pair of said Wings to permit a limited rotary movement of said valve, a valve stem, ste n elevating cam means at the upper end of said stein, a peripheral groove in said stem at its lower end, a socket in the valve,
threaded to fit the lower end a U-shaped cotter a valve in said casing, short fitting in said grooveand socket and a female thread formed in the lower end of said valve in combination with a cap for the lower end of said casing having a tapered elongated stein threaded to fit the female'th'read in said. valve.
4; In a discharge valve for tank cars, the combination witha tubular easing havinga valve seat in one end, a valve located in said easing, short relatively thereto, shaped to iit
