Specification of Letters Patgnt.

Patented. Dec. 4, 1966.

Application filed December 21, 1906. Serial lib. 292,702-

To all whmn it may concern:

Be it known that I, HENRY A. KEINER, a

citizen of the United States, and a resident in As metallic barrels, drums, and similar re-.

ceptacles have heretofore been made, a dithcu ty has been experienced in roperly hoop ing them, in that, since the ceptacles are 'both of metal, riveting of the former to the latter has been the only method practiced, and since these receptacles are usually heavy. and the contents heavy and costly the-blows received by the hoops are a t to loosen the'rivets, occasioning to t e contents and to the receptacles themselves.

My invention relates,. ,therefore, to im',

provements in the construction of drums or barrels whereby the hoops or-strengtheningbands will be most effectively held in position without the employment of any rivets whatever and without forming any holes, scams,

or openings ofany kind whatsoever in the structure of the barrel or drum:

in the drawing hereof, a represents the cylindrical or body part of the rece t'acle- -b b are two heads. The head at t e left shows at 0 another improvement which I have made in these structures, which, however, will not be herein described, since it will form the subject-matter of another application for Letters Patent.

The hoops are constructed and attached to the cylindrical or substantially cylindrical part of the structure as follows: d d are annular ribs which extend circumferentially around the structure. I prefer that these ribs should be continuous; but they may be broken, if preferred. e represents the hoo s, which may be made of sheet metal suita ly rolled or, drawn into substantially the form of the letter U, having stron laterally-ex tending flanges f f. The ann a'r ribs d d, as shown at the left in the drawing, are in the first instance rolled or otherwise formed in the metal composing the drum in such manoops and re'-' ner that they project at substantially right angles therefrom. Thereupon the hoop e is wrap ed about the bodypart of the recep tacle etween these ribs, and when snugly in place its ends are referably fastened together in some suitaljle manner, as by riveting or welding, which will not, however, al ways be necessary, because since the ribs will be forcibly swa ed down u on the flanges ff ofthe hoop it W1ll be rigid y held and no other confining means will be required. It is, however, sometimes a convenience during the process of manufacture, as well as desirable in the finished struoture, to have the ends-of the hoops riveted or otherwise 'fastened together. After the hoop is in place about the body of the receptacle, between the ribs, as stated, then by the operation of suitable mechanism the ribs are rolled down into forcible and preferably clamping contact with the flangesfof the hoop, as shown at the right hand in the drawing, whereby the hoo will be-rigidly and permanently held ace.

It I

the barrel or drum has no seams, openings, punctures, or breaks therein whatever and that the hoops are held in proper relation to thebody of the receptacle in a most rigid, substantial, and ermanent fashion and, furthermore, that t ey are protected against shocks and blows by the overlapping parts of the ribs formed from the body of the recep tacle itself.- Thus not only is thestructure strengthened by the hoop, but also by the corrugated metal compos ng the ribs, and incideiitally the appearance of the receptacle is materially improved.

Inthe drawing I show two hoops only as applied to .a truly cylindrical drum. This is for the sake of simplicity andclearness therein. Obviously the number of hoops and their location upon the drum or barrel, as well as the special-shape of. the-latter, is immaterial.

I claim 1. A metallic barrel or drum having cir cumferential ribs integral with the metal of the barrel itself and a metallic hoop confined between-said ribs by the su erposition of the latter upon the. edges of the 00p.

be noted that under my invention 2'. A metallic barrel or drum having eireumferential ribs integral with the metal .of the barrel itself and a metallic hoop made from sheet metal bent into U- shape anclpro- .5' vided with lateral flanges, confined between said ribs by the su er osition of the latter I upon the flanges of the hoop.

Intestimony whereof I- have signed my name to this specification in the presence of two subscribing Witnesses.

HENRY A. KEINER.
