TAN K-HOOP.

SPECIFICATION forming part of Letters Patent No. 417,381, dated December 17, 1889.

Application filed November 26, 1886. Serial No. 219,976. (No model.)

To all whom it may concern.-

Be it known that I, CosAM TALLEYRAND BARTLETT, residing at Warsaw, in the county of Wyoming and State of New York, havcinvented certain new and useful Improvements in Tank-Hoops, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to hoops for large tanks, especially such tanks as are used for storing brine.

The object of the invention is to producea tank-hoop which shall be oh cap and of convenient application and which shall be durable.

Heretofore hoops for brine-tanks (which are generally composed of wooden staves) have generally been made of flat orband iron, the meeting ends of the band being riveted or welded together, and the hoop was placed over the top of the tank and driven down to tighten the staves. A flat hoop applied in this Way is generally strained most at the lower edge, toward the large end of the tank. As the tanks are often twenty feet or more in diameter, it is difficult to apply such a hoop. As a very large surface of such a hoop is exposed to the corrosive action of the brine, the hoop soon rusts away and must be frequently renewed. Tanks hooped with fiat hoops often burst, causing loss and damage. I

Instead of using a flat hoop, I use a hoop made of round, oval, or similar rods, so thata convex surface of said rods shall bear on the staves; and I connect the ends of the rods is a plan of a modified coupling-bar.

The letter A indicates the staves of the tank, which tank may be cylindrical or tapering.

B indicates a hoop or hoop-section, preferably a round metallic rod about one inch in diameter for large tanks. Oval or similar rods may be used; butI have found round rods to answer to best advantage. One end of each rod may be headed down, or both ends may have screw-threads and nuts applied.

0 indicates the coupling-bar, which is of malleable cast or wrought iron, of crescent form, the inner face of the bar of such curve as to conform to the surface of the tank, the outer face of the bar having at least one lug 1D, through which the rods B pass, said lug having perforations for that purpose. The bar 0 also has two small bosses E, which are either notched or perforated for the passage of rods B.- The bar C may have two lugs D, as in Fig. 8, one end' of a rod B passing through each and tightened, as shown.

The hoop is applied to the tank as shown in Figs. 1 and 7, the latter figure indicating a hoop in three sections. The bar 0 is held tightly against the staves so far as it eX- tends, and as the ends of the bar are thin the rod passes firmly against the staves between these coupling-bars. The lugs E cause the coupling-bar to assume a horizontal position against the staves. The round bar 13 bears against the hoops more uniformly than a flat band, and, as has been stated, is much more durable than a flat band. The lugs E and the rods B serve to support each other, and the hoop can readily be tightened by turning up the nuts. The face of the lug D is preferably beveled, so that the nuts Will have a fair bearing. \Vhile the ends of the rods are far enough removed from the tank to give freedom of movement in turning the nuts, the body of the bar 0 will firmly bear against the staves against which it rests, so that all the staves will be supported by the hoop.

I claim 1. In a tank-hoop, a coupler in crescent form having a boss projecting from its face and provided with two openings, a rounded rod 5 or rods separate from the coupler, detachably seated in said openings, and forming the main part of the hoop, said rod extending around the staves and through the openings in the boss and bearin g on the horns of the crescentshaped coupler, and a nut on one end of said supporting or guide lugs E, all in combinarod bearing against the boss, all combined tion, substantially as described. to substantially as described. In testimony whereof I affix m y signature in 2. A tank-hoop consisting of rounded bars presence of two Witnesses. 5 provided with nuts and a coupling-bar of O. TALLEYRAND BARTLET'J.
