(Cl. 22o-3) 5 Claims;

Vresist external pressure when the tank is located underground. The roof and lbottom are made of spherical segments, upwardly vbulging for the roof and downwardly bulging for the bottom, although they could be just the reverse. The spherical segments intersect on six vertical planes forming hexagons in horizontal projection, except at the periphery where they are broken or incomplete where they join the cylinder. Verti'- cal structural members, capable of acting both in tension and compression, connect the roof and bottom systems of hexagons. These connections may be at the corners where three hexagons intersect or they may be on the line of intersection. In the vertical planes of intersection of the roof and bottom spherical segments are vertical plates connecting the corners of the hexagon systems.

Other features and advantages of my invention will appear more fully as I proceed with my n specification.

In those forms of device embodying the features of my invention shown in the accompanyl a cylindrical sneu lo closed at the top by a roof made of spherical segments II bulging upwardly. The lower end is closed by a bottom made of spherical segments I2 bulging downwardly.

The cylindrical shell I0 is here shown as reinforced by the internal horizontal angle irons I3 which are particularly desirable to brace the tank against external pressure in the event that it is used underground. f

The lines of intersection Il of the spherical segments of the roof form hexagons. (See Fig.

the spherical segments of the bottom form hexagons.

In the vertical planes o1' intersection of the roof and bottom spherical segments are vertical plates I6 (at the top), and I1 (at the bottom).

.connecting the corners of the hexagon systems.

Each plate has a curved edge on the junction arc of adjoining spherical segments. The plates at the top are extended downwardly somewhat and those at the bottom are extended upwardly somewhat so that the straight edges I6a and IIa will lie some distance from the plane of the corners I8 (at the top) and I9 (at the bottom).

20, 20 indicate vertical braces adapted to take both tension and compression strains. 'I'hese connect the corners of the roof and bottom systems of hexagons. In the form of device shown in Figs. 1 to 4. the ends of these members are joined to the vertical edges of the plates I8 at the top and the plates I'I at the bottom. It will be seen that the braces 20, therefore, have their upper and lower ends each joined to the edges of three of the vertical plates I6 or I1. It is to be understood that all joints and connections are made by welding, or other suitable means.

The form of device shown in Figs. 5 and 6 is generally the same, corresponding parts being indicated by corresponding numerals augmented by |00. The plates IIB andIIl, corresponding to the plates I6 and I1, however, are made somewhat narrower, the long straight edges thereof lyin'g substantially in the plane of the corners II8 at the top and IIB at the bottom. In the 1.) Similarly, the lines of :Intersection- I5 of 55 form of device shown in Figs. 5 and 6 the angle iron braces |20 are substituted for the posts 20. They join opposite plates IIS and III substantially at their mid points and are adapted to take both tension and compression. Withthe braces moved from the corners to the centers of the plates, the lower edges ofthe plates are somewhat extended so that they will join as indi- -cated by II8a at the top and similarly at the bottom The form of device shown in Fig. 7 resembles that shown in Figs. 1 to 4 except that the spherical segments of the top and the bottom bulgeinwardly instead of outwardly. In this gure corresponding parts are indicated by corresponding numerals augmented by 200.

The foregoing detailed description has been' given for clearness of understanding only, and

no unnecessary limitations should be understood therefrom.

What I claim as new and desire to secure by Letters Patent is:
