BARREL.

Specification of Letters Patent.

Patented Ju1y 24, 190e;

.ippiiman 218,1 rune 21,1905. serial No. 266,216.

l citizen of the United States, residing at the flange of the city of New York, in the State of New York, have invented new and useful Improvements in Barrels, of which the following is a specification.

My invention relates to metal barrels adapted to contain oils, chemicals, and other liquids requiring absolutely tight joints.

In structures of this character used heretofore the head has been secured to the shell by means of rivets, brazing, and by both rivets and brazing. Rivets alone do not make a satisfactory joint, and brazing-solder affects injuriously some chemicals, which prohibits its use for such pu oses. Brazing, moreover, is diiiicult an expensive, especially when ap lied in a circular line to join a head with a s ell. To overcome such disadvantages, barrels have been made wherein a joint between the shell and head is formed on a hoop having a recess into which the ed` es of the shell and flange of the head are rol ed' and clamed therein around a shoulder of the hoop y means of a flange pressed into such recess. In such construction,v however, considerable diiiculty has been found in maintaining the end of the shell and flange of the `head clamped tightly around the shoulder of the ho'o by means of the edge of the oop. In such construction, moreover, when the hoop is bent slightly, as when a barrel with its contents is upended carelessly or the barrel is ermtted to fall heavily on one point of the oop, the edge of the ange is drawn away from the shoulder of the hoop, and the shell and flange of theA head become loosened slightlyat such point and cause the barrel to leak. In such a case it is practically impossible to bring the hoop back ,jto its original shape and re-form the joint.

My invention has for its object to secure the head to the shell or' a barrel by means of a tight joint formed without the use of rivets or brazing and adapted to be maintained in a serviceable condition. This I accomplish by the means illustrated in the acompanying drawings, in which- Figure 1 is a side elevation of a barrel embodying m invention. Fig.- 2 is a vertical section of t e same.

As illustrated in the drawings, A represents a cylindrical shell having its ends inclined inward and provided with a circumferential riba, extending outward and ab ruptly from the shell, thereby making'an annular shoulder af, an ular in cross-section with the end of the she l. A head B, having its circular or body portion preferably concavo-convex in cross-section, is provided with a cylindrical iange inclined inward and ada ted to bear against the inner end of the she A. A rib b, corresponding with the rib a'of the end of the shell, is formed in the lan e of the head, extendin outward from the an e of the head abru t so as to form an annu ar shoulder b angu ar in cross-section on one side of the flange and a corresponding annular recess on the o posite side. The shoulder a of the end ci) thel shell is compressed and embedded so closely into theaunular recess of the flange of the head as to make an absolutely tight joint between such parts, through which even oils and chemicals cannot leak. The outwardly-extendin portions of the interlockin ribs of the she l and head are, moreover, (Irawn so tightly together as to revent any leakage between such parts. his is accomplished by first forming the rib in the end of the shell and pressing the rib into the flan e of the head, so as to en age the rib of the s ell.

A head-and C is applied to the end of the shell and lange -of the head to protect such arts and take the strain from the end of the barrel. This band has an inclined wall bearing against the iiange of the head with its lower portion extending referably to the circular ortion of the hea and the band is provide with a flange c, which is turned over onto the outer extremity of the shell, with its ed e referably bearin against the rib of the s ell), so as to clamp ihe shoulders of the head and shell and bind them tightly together. By means of such construction a tight joint between the end of the shell and flange of the head is maintained even when the outer edge of the head-band nas become IOO bent slightly, for the reason that the joint is the shoulders of the shell to become loose and start a leak, the angular shoulders of the shell and head-band ma be re-formed and the vjoint restablished y bending the surplus metal forming the ribs over toward the edge of the flangeof the head-band and the leak stop ed without re-i'orming or rebending the hea -band itself.

The shapeof the ribs may be modified.

y thereby in the end of the shelland flange of the head.

What I 'claim as new, and desire-to secure by Letters Patent, is-

Ina barrel, the combination with a shell, having its end inclined inward, of'ahead hav-- ing an inclined flange,- and a head-band havin an inclined Wall bearing against the lange of the head and'provide with a flange adapted to clamp the edges of the shell and ange of the head, the shell and flange ofthe head being provided With interlocking ribs and annular angular shoulders compressed tightly together and formed independently zo ROBERT W. HARDIE.
