Specification of Letters Patent:

Patented March 3, 1908.

Application filedApril 19. 1906- Serial No. 312.694.

To all whom it may concern: Be it known that I, FRANK B. WENT- WORTH, a citizen of the United States, and

resident of Independence, county of Montgomery, and State of Kansas, have invented certain new and useful Improvements in Tanks, of which the following is a specification, and which are illustrated in the accompanying drawings forming a part thereof.

The invention relates to tanks of sheet 'metal, and particularly to those which are of generally cylindrical shape and have walls composed of a plurality of sections.

- The invention has for its object to provide simple and eflicient means for uniting the several sections of the walls of the tank of the kind described, and to increase the strength and stiffness of such tanks, thereby rendering them less likely to become indented or misshapen-by rough handling or. in transportation from place to place:

The invention -is exemplified in the structure hereinafter described and illustrated in invention; and Figs. 2, 3 and 4 are sectional the accompanying drawings, in which Flgure 1 Ban elevation, partly in section, of'a tank constructed in accordance withthe details of-the same drawn to a larger scale.

The invention is applicable tosheet metal tanks of various forms.

In the drawings is shown acistern for the storage of liquids which, in practice, Will usually be of moderate size. Its walls are preferabl iron and ormed in sections, 10, 11, 1'2, 13 and 14, one of these sections, as 10, being of the proper shape'to provide a bottom for the tank, while another, as 14, may form a domeshaped or conical top having a filling opening 15. The remaining sections, 11, 12 and 13, as shown, are cylindrical in form and compose the body wall of the tank.

In carrying out the invention there is provided a plurality of metal bands or hoops 16 of channel section, each preferably having its

flanges

17, 18, directed outwardly. These hoops are most conveniently formed by bending a strip of channel iron to a circle and uniting the ends in any convenient manner, as by means of a tie plate 25 and rivets 26. Preferably the hoops 16 are of-galvanized material and one of them is employed for nection.

of a heavy grade of galvanized uniting each of the sections of the tank with the next adjacent section. In forming this connection the hoop member is, as shown, placed within the tank and the meeting edges of the tank sections are flanged inwardly, as indicatedat 1 9, 20, Figs. 3 and 4" of the drawings, the flanges being then fitted into the groove of the hoop member '16 and boundin position by means of a band 21 preferably of round iron" or stout wire; If desired the joints thus formed may be sweated or calked with solder. As shown a liberal amount of soldering material 22 is applied about the binding member 21,

to give thejoint a smooth or finished a pearance, while some of this solder issoa ed 0r sweated intov the joint to unite the

flanged edges

19, 20, of the tank sections with'the web of the hoop member 16, as'indicated at 23, thus forming a perfectly water-tight oonr' In the form of tank shown in the drawing, the rim of the filling opening 15 isstrengtherred bya tubular hoop 24, to which the edges of the upper section 14 of the tank are fitted and united by screw-bolts 27.

By the improvement herein shown and described, there is provided a sheet metal tank of great dur ability and strength, as the hoop memberslfi serve not only as a convenient means for uniting the several sections of the tank but, also effectively resist various forms of rough usage to which it may be' subjected and which might otherwise seriously distort orpuncture its walls.

I claim as my invention In a tank having sectional walls of sheet metal in combination, a circumferential hoop of channel section having its flanges directed outwardly, contiguous edges of adjacent wall sections of the tank bein flanged inwardly and laid in the groove of t e chan nel, a band surrounding the tank and bearing upon the edges of the wall sections within the groove, and a calking of solder for the joint thus formed, the solder being applied over the band. i I
