\v LAN L55 EF; s5. L. M; 4 36 Q UNITED sTA'rns PATENT OFFICE- LEONHARD BAUROTH, OF TOLEDO, OHIO, ASSIGNOB TO THE METALLIC BARREL COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.

SHEET-METAL BARREL.

Specification of Letters Patent.

Patented Dee. 15, 1914.

Application filed November '21: 1908. Serial No. 463.819.

the same, reference being bad to the aceompany ng drawings, and to the figures ot' reference marked thereon, wlneh liorni a part of this specification.

My invention relates to metallic receptacles, and particularly to sheetanetal barrels of the class having spaced erinips or ribs ellicient and reliable means for obtaining the proper strengthening effect against external compressing forces, with the result. that my barrel or rereptarle possesses the necessary strength and rigidity without obstruction to the interior of the barrel or withoutlessening the capacity thereof.

Further objects of the invention. as well as the construction and arrangement of the phrts thereof. are fully described in the fol lowing specification. and a' preferred embodiment thereof illustrated in the aceonr pan ving drawings. in \\'l]l('ll,

Figure l is a side ele\ation of a barrel embodying my invention. with portions of the same broken away. Fig. 2 is an end viewdlrereot with a portion in section on the line .11 r in Fig. 1. Fig. I: is an enlarged elevation of a. portion of the barrel. with the part A ll thereof in vertical sertion. as on the. line :1 1:1 in Fig. "l, and the part A therei'if in vertiral sertiou, as on the line 3/ y in Fig. and Fig. 4. is an enlarged portion of one end of the barrel with the head removet'l.

Referring to the drawings. 5 designates the body of the barrel. and t G the opposing heads thereof. The body 5 is preferably formed from a cylindrical sheet-metal blank. which provided with the inwardly pro ecting long'itudinallr-extending erimps' or furrows 7. at suitably spaced distances thrrearound. whirh serve both to strengthen the body against external compressing stresses and .to nnpart the desired bilge formation thereto. which latter is accom-' plished by gradually deepening the-crimps from the. center toward the ends thereof to irimortionately increase the amount of metal taken up thereby. 1 wish it Linden. stood, however. that. I do not wish to restrict my in ri-ut-ion'to use in connection with any pariirular shape or formation of rei-optaele. whether of bilge form or otherwise. or to a ny particular manner of forming: the same.

'ln the base of each of the crimps or furrows 7 is disposed a reinforcing rod or heavy wire, which is firmly held therein by drawing the outer opposing edges of the crimp together so that they abut, or sub stautially abut, as shown at 9, Figs. 2 and l. The elosing of the mouths of the crinips also gives one side of the package the appearanee of a substantially plain-or unintorrupted surface. Inorder to prevent a longitudinal movement of the rods within the crinips, their ends are terminated short of the ends of the erinips, as shown in Fig. 23. and the ends of the erimps bent laterally or radially and flattened against the inner end portions of the body, as shown at 10, thus Closing the ends of the crimpsover the rod ends and forming internal shoulders 11 upon which the heads (3. (i may seat. Hy securing the rods 8 within the crimps in this manner it is evident that the barrel body is made very rigid in its construction and is capable of resisting very great external fol-res: and also that: the bending of the crimp ends closely over the rod ends and radially flattening them against the reeepiaele. body absolutely secures the rods ainst longitudinal moveuwnts within the rrnnps. reinforces the body chime and forms liriu, rigid seats for the receptacle heads.

in the present instance the body 5 is encircled by a plurality of hoops 12, which are riveted or secured thereto in any other suitable manner,,and prevent an expansion of the body or an opening of the crimps from their closely compressed state, as shown.

The heads 6 are shown as being stamped from sheet-metal and have their major portions depressed to adapt them to fit snugly within the end portions or chimes of the bar re]. and seat on the shoulders 11 formed at the end portions of the crimps. The chime at each end of the body 5 has its edge preferably rolled outwardly to torn; a hoohcd edge with which the marginal edge of the respective head (i may engage, said edge of the head being rolled over the chime and interlocking with the edge thereof, as shown at 13, Fig. l, and the whole then closely compressed to form a firm joint. To prevent an opening of the joint thus formed the end of the barrel is encircled by a hoop or hand 14, which is secured in position by rivets 15, or the like, passing through it, the chime and outwardly projecting portion of the head. It will be understood, of course, that the heads of a barrel are not intended. to be taken off after once being placed thereon, as the barrel is filled and the contents withdrawn therefrom through the bung-hole 16.

I desire it to be understood that my insuch limitations are specified in the claim.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is,

A bilged metallic receptacle having a pinrality of inwardly projecting crimps formed longitudinally thereof a reinforcing rod dis posed Within each crimp and bowed to conform to the bilge of the receptacle with the mouths of the crimps drawn closely together around the rods to retain them therein and to provide the receptacle with. a. substantially uninterrupted circumferential surface, said rods having their ends standing inward greater distance from the receptacle wall than the central portions thereof and terminating short of the respective ends of the receptacle, and the crimp ends being bent closely over the rod ends and fiat against the receptacle body whereby to secure the rods in place and to cooperate with the lflfiitllli'lr ing ends thereof to form firm seats for the receptacle heads, substantially as described.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
