' VENT FOR ACID OR OTHER TANK-CARS.
Specification of Letters Patent.
Patented. July 9, 1912.
Application filed December 3, 1910. Serial No. 595,435.
To all whom it may concern Be it known that I, EUGENE H. WoLrr, a citizen of the United States, residing at La Salle, in the county of Lasalle and State of Illinois, have invented a new and useful Vent for Acid or other Tank-Oars, of which the following is a specification.
My invention relates to improvements in vents for acid and other tank cars in which the fumes or gases from the acid or other liquid contained in the tank may readily escape; and the object of my improvement is to produce a vent for tank cars, particularly used in shipping acids, that will not permit the escape of any liquid contained therein no matter how roughly the tank is jolted on the railroads, and at the same time permit-ting the gases to escape and preventing the rain from entering the tank.
It is well known that the tank cars used for the shipping of acid are a source of great danger to train men in particular and the traveling public in general, because of the escape of the acids contained therein through the vents which permit the gases to escape. My invention completely overcomes this danger, making the person of the attendants around these tank cars absolutely safe and at the same time does it for a very little expense. I attain these objects by the mechanism illustrated in the accompanying drawing, in which-- Figure 1 is a top view of my invention. Fig. 2 is a cross sectional view along a line AB of Fig. 1.
Similar numerals refer to similar parts throughout the several views.
In the drawings 1 is a chamber or spherical cavity which I have here shown formed of a lower portion 2 and an upper portion 3, which parts are fastened together by means of the cap bolts 6. Part 2 has a lower cylindrical portion 12 having an aperture which communicates with 1, which aperture I have fitted with the screw threads indicated. By means of this part 12 I connect my vent with the tank by means of a pipe 13. The part 3 has a hooded portion 4 which protects a series of apertures 5, which communicate with chamber 1, immediately adjacent to and beneath the edge of the hooded part. This part 4 has a recessed portion 10 into which is, fitted a hollow or tubular member 7 which I have shown fastened into the aperture 12, by means of a threaded portion indicated by the dotted lines at 11. Member 7 instead of entering the recessed portion 10 as shown may simply extend upwardly to the inner surface of the hooded part 4. Member 7 has a plurality of apertures 8 immediately adjacent to the inner surface of 1 and a number of apertures 9 located somewhat above these apertures 8.
From the construction of my vent it is evident that the gases can readily escape to theatmosphere by means of the apertures 8 or 9 and 5, but that any liquid which may come up through the pipe 13 into 1 can immediately drain back again into 13 through the apertures 8 and then back into the tank.
It will be understood, of course, that while I have shown one form of my device as I prefer to have it constructed in practice, I do not wishto limit myself to the exact const-ruction shown, but wish to have it taken in a sense illustrative of any and all the forms of same which come fairly within the scope of my claims.
I claim:
1. In a vent for tank cars, a chamber having apertures adjacent to the upper wall thereof, a projection formed on the lower end of said chamber having an aperture communicating with the interior of said chamber, means for fastening said projec tion to a tank, means for protecting the apertures adjacent to the upper wall of said chamber, and a hollow member extending upwardly into said chamber with apertures in the wall of said member communicating with the interior of the chamber and the aperture in said projection.
2. In a vent for tank cars, a chamber, a
projection formed on the lower end of said chamber having an aperture, means for fastening said projection to a tank, a hood formed on the upper portion of said chamber with apertures adjacent to and immediately under said hood leading into said chamber, a tubular member with apertures in its base fastened in the aperture in said projection and extending upwardly into said chamber.
3. In a vent for tank cars, a receptacle having apertures in the upper portion thereof, a projection formed on the lower portion of said receptacle having an aperture, means for fastening said projection to a tank, a tubular member having a plurality of apertures fastened in the aperture in said projection extending upwardly into said chamber and means for closing the up per end of said tubular member.
l. In a vent for tank cars, a chamber having an aperture in the base thereof, means for connecting said chamber to a tank, a projecting hood formed on the upper portion of said chamber having apertures adjacent to and immediately under said hood, a tubular member having a plurality of apertures fastened in said aperture in the base of said chamber and eX- tending upwardly to the inner surface of said hood.
5. In a vent for tank cars, a chamber having an aperture in the base thereof, means for connecting said chamber to a tank, a projecting hood formed on the upper portion of said chamber having apertures adjacent to and immediately under said hood, a recessed portion in the lower surface of said hood, a tubular member having a plurality of apertures in its lower portion fastened in the aperture in the base of said chamber and extending upwardly into said recessed portion.
6. In a vent for tank cars, a chamber having an aperture in the base thereof, means for connecting said chamber to a tank through said aperture, a projecting hood formed on the upper portion of said chamber having apertures adjacent to and immediately under said hood, a recessed portion in the upper surface of the chamber,
and a tubular member having a plurality of apertures extending from the aperture in the base of the chamber upwardly into the recessed portion.
