To aZZ whom t may concern.; 7 v Be it known that I, LEwIsfV. MATHER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Metal Kegsor Casks, and

'declare the following to be a full, clear, and

exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to kegs or casks and has for its object a cask in which the hoops and the head rings are applied to the shell in an improved manner.4

This invention is intended as an improvement over the invention shown 'in the pat ent of Messrs. Heutteman, Cramer, Veideman, and Schaum, No. 1,086,826 of Febru@ ary 10, 1914.v y

This invention consists essentially in the utilization of spring tongues on the shell or staves of the cask which spring out and lock with the hoops and the. head rings whenthe latter have been slipped into place.

In the drawings,-Figu're 1, is a fragmentary View of a caskpartly in section. Fig. 2, is al fragmentary perspective of one of the stave-sheaths that form the outer shell. Fig. 3, is a fragmentary view of a modified form of Cask shown partly in section. Fig. 4, is a fragmentary perspective of the stavesheath. Fig. 5, is al fragmentary View of.

the stave-sheath showing the spring tongue attached to the stave. Fig. 6, is a detail in perspective of the spring tongue.

The caslr consists of heat-insulating filler 'material a packed about the inner container 7) and an outer shell c.

wardly-directed corrugation j. These corrugations form recesses into which the spring tongues 7c arel adapted to lspring when the hoops and caps have been thrust upon the stavesheaths and into position. These spring tongues lc are for-medjby cutting out a portion 4 of `the stave on three sides leaving one .sideas a hlnglng. axis. This cut-out portion is then drawn into cup-form by forcing the middle of .the cut-out portion inward beyond the surface of the stavesheath. After the stave-sheath has been ,assembled over the filler material., which is of a compressed nature, the filler material by lts springy action always tends to throw the spring tongue outward. When 'the hoo s and the vhead rings are forced over tiie staves the spring .tongues are temporarily pressed into the filler material, but when the 'hoops and' head rings have .been vforced far enough upon gthe staves t0 bring the ,re

cesses formed by the annular corrugations adjacentv the tongues, the tongues spring into the recesses formed by the annular corrugations and permanently lock the hoops and the-head rings in position.

In Figs. 3 to @inclusive I haveishown a modified form in-j'which a separate plate Z 1s used as a spring tongue. This plate Z is a curved plate, as shown in Fig. 6. It is provided with a pair of struck-out ears m. The depression a is made in the surface of the stave by a suitable die, but the lugs o are cut out of the metal forming this depression and are left almost flush with t-he main surface of the stave at the topl of the depression. These lugs o are adapted to be bent over the ears m of the spring plate (see Fig. 5) to .hold the plate in place. The spring plate or tongue Z is slipped into the depression and the ears m will register with the lugs o. The ears and the lugs canv be omitted and the spring plate spot-welded to t-he stave-sheath. The original 'curvature of the plate tends to throw the spring tongue out as shown in Fig. 3. However, f inasmuch as the plate and the spring tongue Z are made of thin metal, when the hoops and the caprings are forced upon the staves th'ef spring tongue or-plate Z are tem? porarily forced into the depression n,- until. the hoops and the head rings have been forced far enough on the stave-sheaths to bring the annular recesses adjacent the spring plates, whereupon the spring tongue or plates Z will immediately spring out and engage in the annular recesses. This permanently locks the hoops and the cap rings has the advantage of being both permanentand `being invisible in thev Completed Cask.

Referring to the spring tongues in the' claims, the term is used in a broad sense `to include not only a tongue such as le but also plates such as Zand any other projecting element which would properly come within the designation.

7What I claim is:

1. .A Cask, having in combination, a container, filler material thereabout,` an outer sheathing about the filler material and having metallic portions provided with hinged tongues that by reason of .their hinging action may be pressed from a position of projection with respect to the. outer sheath ing to a position interior ofthe outer surface of the outer sheathing, and a ring or band member for fitting over the outer sheathing and provided with an inwardly opening recesswhereby the band may be slipped over the outer sheathing and the hinged tongues which are temporarily pressed out .of projecting relation with respectto the sheathing to allow/'the said ring or band to pass over them and which subsequently spring back into the recess of the band or ring to lock the same tothe sheathing.

2. A cask, having in combination, a container, filler ymaterial thereabout,an outer lsheathing inclosingthe liller material and provided with a plurality of tongues, each of which is fixed at one edge with respect to the sheathing and which is free at all the other edges, the said tongues being arranged to normally project from the face of the sheathing, but being capable of being forced below the surface of the sheathing, and a band or ring itting over the outer sheathing and having an inwardly opening recess into which the tongues spring When the recess is brought into registry with the same.

Y In testimony whereof, I sign this specifi.

cation in the presence of two witnesses.
