TO WHOM IT MAY CONCERN:

Be it known that I, JOSEPH G. MOODY, of New York, in the county and State of New York, have invented certain new and useful Improvements in Tanks or Yessels for Holding Hydrocarbon and'other gaseous and ,inflammable Liquids; and I hereby declare the following to be a full, clear, and exact description oi' the same, reference-being had to the accompanying drawing, which represents a longitudinal vertical section of an oil'- boat with my improvements applied.

The object of my invention is to provide for the safe discharge of the iniiammable and explosive gases generated within tanks or receptacles containing hydrocarbon liquids. In ordinarytanks or vessels of this descriptionfthe gases are discharged into the surrounding air, and they are therefore very liable to become ignited and to explode, causing the destruction of the tanks, and oftentimes the killing or disabling of persons standing near. My invention consists, essentially, in conducting ,the gases from the tank as soon as they 'are generated, and dischargingthem into water or other uninilamrna'ble- `liquid medium, so as to keep them from all direct contact with the air, thus rendering the operation of discharging them safe and easy.

The boat, or oating oil receptacle, A, shown in the drawing, is an ordinary tank, containing no other liquid than the oil, the level of which is Aindicated at a a.' B is the supply tube, which, when not in use, is hermctically closed. From the dome C which rises from the centre of the tank, and in which the gases generated by the liquid accumulate, there extends a ,discharge tube, D, whose other end, d, is carried .over the side of the boat and/bent so asto be plunged in the water below' the water-line b, as shown in the drawing; The orifice d of the tube is turned upwards; but it is obvious that it may be bent in any direction so long as it Ais covered by the water; and so the tube D, instead-of beingfcarried over the stern of the boat, may extend over the sides or any other partgof the boat. When the tube is thus placed below the water-lindo b, there is a constant equilibrium maintained between the gases 'and thewatexy and, in proportion as the pressure of the accumulated gases exceedsjthat ofthe water, the former are discharged from the -Orificed, and enter the water, with which they becomedncorporated. It will thus be seen that, although the mouthof the tube D is' always `leftlopen, yet, as there is an uniniiammable liquid medium interposed between it and the air, there is no possibility of re or other igniting agent reaching the interior of the tank through the tube and there can be no great accumulation` of gases within the tank, as they arc discharged through the tube almost as fast as they arcgenerated. Although I have shown my invention used in connection with a floating tank, itjwill, of course, be understood that it can e be applied with equal facility to any othekind of tank, whether surrounded by water or not. 'The only essential is, that the mouth, or the open end, of the tube D shouldbe covered by o1`- immersed in water, as above explained, and this may be accomplished by plungingit into a tank or small reservoir of water, or othersuitable means maybe employed.

Having described my invention and the manner in which the same is or may be carried into e`ect, what I claim, and desire to secure by Letters-Patent, is v 1. The method of discharging the' gases generated within. the tank, or other receptacle containing the hydrocarbon liquid, into -an uninammablc liquid medium, substantially as shown and set forth.

2. The combination, with .a Boating tank, or other receptacle for hydrocarbon liquids, of a gas-discharge tube, attached to the dome, or upperfpart of said tank, and havingits mouth, or-open end, immersed in and surrounded by water, substantially as and for'the purposes described. v

In testimony whereof lI have signed my name to this specification before two subscribing witnesses.
