To all whom it may concern:

Be it known that I, WILLIAM ScHnU, a citizen of-the United States, and a resldent of Maywood, Cook County, Illinois, have 1nvented certain, new and useful Improvements in Multiple-Compartment Tanks, of which the following is declared to be a full, clear, and exact description.

This invention relates to multiple com-- partment tanks, .and its principal ob ect is to'p'rovide a leak proof, sheet metal tank, having a plurality of separate compartments for storing liquids, such as oils, gasoline and so forth. Tanks of this character are usually made of sheets of metal, welded together, and where a partition is employed for dividing the tank into two or more compartments, much dificulty' is encountered in producing a leak proof tank, having a neat, finished appearance at the joint between the partition and side .walls thereof. According to the present invention I make all of the joints between the partition and side walls, at the cornersof the tank, by welding the parts together,'and-this permits any surplusmetal at the welded joints to be ground away without weakening the joint. The top and bottom pieces are also welded in place on the side walls and end walls. In accordance with this invention a leak v proof multiple'compartment tank is produced economically, and in less time and withless labor than is ordinarily required for constructing a multiple compartment tank of equal capacity.

The invention is clearly illustrated in the accompanying drawing in which F g. 1 1s a perspective view of a multiple com artment'; tank embodying the referred orm-of-the present invention; ig. 2 1s a perspectiiie view illustratin one of ig. 3. is a vertical, longitudinal section taken on'the line 3-3 of Fig. 1; Fig. 4 is a vertical cross section taken on the line 4-4 of Fig. 3; Fig.

5 is a vertical cross section taken on the line 55 of Fig. 3; Fig. 6is a view looking at the bottom of the tank, and Fig. 7 is a plan of a modified form of the invention.

Referring to the said drawing, and first to Figures 1 to 6 inclusive, the

reference characters

10, 11 designate the side and'end walls, 12 the top, 13 the bottom pieces, and 14 the partition. The tank is preferably rectangular in form, and the partition di ,tend a rose the end welded together at the corners 16. The partition 14 extends across from one side wall to the, other, and preferably in an oblique direction, and has

end portions

14, 14 that run to the corners 16 of the tank and are welded to the side and end walls thereat. The upper and lower edges of the partition are welded to the top piece 12, and bottom pieces 13. The top 12 comprises a single sheet having down turned flanges 12 which fit inside the top portions of the side and end walls, and are welded thereto. The top is also welded to the partition. The bottom comprises two bottom portions 13, each having down-turned flanges 13 welded to the lower edge portions of the side and end walls and to the partition.

Tn constructing a tank in accordance with the present invention, each side and end wall sheet is bent up to form a right angle bend, the'two bent parts of the sheet forming one side and one end wall of the tank. The flanges of the top sheet 12 are bent up, and the corners between the; flanges are welded together. The bottom sections are formed up with the flanges 13 and are made of a size and shape to fit in the spaces at each side of the partition. (See Fig. 6). The partition sheet is notched out at 14 and bent at two places adjacent the ends, to form the main or oblique part 1t and the two end portions 14. The notches 14 are made as high as the flange of the top sheet and exportions 14 to the ob lique rtion 14.

In assembling'and welding the parts toether, the top piece 12 is first inverted (see ig. 2), the partition 14 set upon it, with the notched end portions standing over the side flanges of the top piece, and with the edges of the end portions 14 flush with the outer faces of the end flanges of the top piece.. The partition and top piece are then welded together along the entire line of contact between them. The welding is done by the electric welding process or by an acetylene oxy en weldin process as desired.

-Afterwar s the. two side and end wall sheets til) , ing may welded to the side and end walls and to thepartition, thus completing the tank,

It is to be observed that all of the weldoutside of the tank structure as it is being constructed, and that" when completed the welded joints may be ground to make a neat finish, without weakening them. The completed tank. is enameled, or surface finished in accordance with any of the well known methods, and mounted on a base or on wheels, as is customary. Whenused for dispensing oils, holes are formed in the top, one over-each compartment, and ,suitable pumps (not shown) aremOunted on the top and secured thereto in the usual manner. By running the partition across at laces remote from the corners, both open- I ngs may be symmetrically disposed on the lln the modified form illustrated in Fig. 7, the partition 14 is shown as extending diagonally between opposite corners of the tank. In otherrespects the construction of this form is similar to the preferred one.-

From the'above it is evident that any danger of leakage from one compartment to anotheris eliminated. Moreover, the

partition-acts as a brace between the walls and increases the stability of the tank;

More or less variation of the exact details of construction is possible ,without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shownand described, but intend, in the follow ing claims, to point out, all of the invention disclosed herein. 1 I claim as new, and desire Letters Patent:
