Application filed. December 13, 1921. Serial No. 522,099.

To all whom it may concern:

Be it known'that I, ARTHUR S. COOPER, a citizen of the United States, and a resident of Santa Monica. in the county of Los Angeles and State of California, have-invented a new and Improved Tank, of which the following is a full, clear, and exact description.

This invention relates to improvements in tanks for the storage of oil or other liquids which are lighter than water.

An object of the invention is to provide a bottomless tank of this character partly submerged in a body of water so that it will be in a convenient position for storage of fuel oil.

A further object is to provide such a tank in which the oil level is maintained at constant height by the surrounding body of water, and a tank which will be simple and practical in construction, durable and citicient in use and comparatively inexpensive to construct.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and. arrangements of parts as will be more fully hereinafter described. and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a perspective view with parts broken away and in section. for clearness, showing one of my improved tanks in ap plied position;

Figure 2 is a view in section through the tank illustrating a modification; and

Figure 3 is a similar view illustrating an other modification.

Referring in detail to Figure 1 of the drawings, it will be seen that I provide a circular series of piles 1 driven into the bed 2 of a body of water 3. Brackets 4 are secured to a submerged portion of the piles. My improved tank comprises a cylindrical open ended body such as 5, which fits within the circular series of piles and is supported upon the brackets and has its upper end projecting above the surface of the water. This body may be formed from one or more sheets of metal having their edges overlapping or joined together in any approved manner, as indicated at 6.

7 represents a floating cover fitting within the tank and provided with openings such as 8, to accommodate inlet and outlet pipes 9 and 10 respectively. It will be apparent that when oil is poured into the tank through the inlet pipe 9, it will displace the water which is in the tank, the water being forced out through the lower end of the tank and since the oil is lighter than water, no oil will escape. As the oil is pumped out of the tank, the water pressure from underneath will constantly maintain the oil level in the tank at a slightly greater height than the water level outside, due to the clifterence in specific gravities of the two fluids. Any suitable pumping apparatus (not shown) may be utilized to remove oil. The floating cover prevents evaporation and the entrance of foreign'matter through the top of the tank and the piles prevent lateral movement or sinking of the tank.

In Figure 2, I have illustrated a slight modification which may be used where tanks are constructed in bodies of water having a periodically varying depth. In Figure 2, the reference numeral 11 represents the tank and 12 represents one of the piles. Instead of securing a bracket to the pile as shown in Figure 1. the tank is supported upon a chain 13 secured to the top of the pile and any suitable hoisting apparatus, designated by the reference numeral 14: may be utilized for manually raising the tank in case the body of water by which the tank is surrounded rises to a threatening level.

Figure 3 illustrates another modification, wherein a stationary cover 15 is substituted for the floating cover 7.

These tanks may be constructed in rivers, lakes, bays, or any other body of water in which the currents are not too great. The water pressure on the outside of such tanks tends to prevent a leakage of oil through the joints between the plates forming the tank so that they will prove highly efficient in use and that there will be absolutely no loss of oil.

Although I have illustrated certain of the preferred embodiments of my invention, it will be evident that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention, and hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such slight changes and. alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

5 1. An oil tank including an open ended the casing to prevent lateral displacement,

thereof, and a floating cover positioned in 10 one end of said casing.

2. An oil tank including an open ended casing adapted to be partially submerged in a fluid, a floating cover movable in one of the open ends of said casing and means exteriorly of said casing for preventing lateral displacement thereof and for limiting the vertical movement thereof in one I direction.

ARTHUR S. COOPER.
