Application tiled December 12, 1925, Serial No. 75,133, and in Germany September 7, 1525.
My present invention relates to the man- .ufacture of containers having longitudinal corrugations and tapering toward one end or both ends, such containers being generally in the nature ofbarrels or drums. nection with these containers there is ,employed at the end or at both ends a so-called ring seat which receives and holds the cover of the container and also the fastening or.
locking means by which said coyer is secured. In my pending application, Serial No. 751,-
527,filed in the United States Patent Oflice.
on November 22,1924, I have. described a method according to which the ends of a longitudinally corrugated container body of the character referred to are converted by a combined pressure and drawing operation, into a smooth non-corrugated edge or end portion. My present invention relates to a further developmentof such earlier process.
According to my present invention the smoothed edge of thecontainer is pressed outwardly to form a ring of angular or semi: circular cross-section which may constitute directly the support for the cover and which in conjunction with a ring placed in contact with its periphery, either inside or outside, I will either form a two-part ring seat or serve to'receive a unitary ring seat having the sameurposes as referred to above and also descri ed in my application for a patent filed in the United States Patent Oflice on Novemher 6, 1924, Serial No. 748,032. When the ring seat is to be a two-part structure, the
,ring placed around the angular edge of the contalner may be used as a mold or guide for said edge, so that the ring and the edge of; the container will be pressed together 'firmly and securely connected by the very act of shaping the edge .of the container into the surrounding ring. The upper or outer flange of this ring serves as a backing for the expanding ring or other locking means which serves to. secure the cover in position. \Vhen employing that term of my present invention in which the'e'dge of the container isformed or molded into the surrounding ring, I prefer to rovide saidring with a downwardly exten mg annular flange which is vertical or approximately so, to lie substantially in line with the corrugations of the container. The inner face of this flange is smooth and the pressing or smoothing out In conto give it at the same time a proper sha .cooperate with the ring seat. This s ape of the corrugations begins at the loweredge like container embodying my present invention; Fig. 2 is a top view thereof, and Figs. 3, 4 and 5 are partial longitudinal "sections illustrating three additional modes of carrying out my present invention. a
indicates the longitudinally corru ated bod of acontainer and b designates t e smoot I end portion of such.body, which has been made smooth by a combined pressure and drawing operation such as referred to above. According 4 to -my present invention, this pressure and drawing operation is performed in such a manner as not only to smooth the end portion of the container but to maybe asim'ple angular form of L-shaped cross-section, as in Fig. 1. The lower member of the L-sha'ped portion will form a seat for the packing g and will also be engaged onthe opposite side by the lower flange of the ring a; the upper flange of which is engaged by the locking means, such as the end-portion b of the container body a and said container portion is extended inwardly at its edgeto overlap the upper flange of and the 100 'ng expanding splitring h, which"alsoeng%ges said ring, as shown at b. In this construction, the packing 9 does not engage the body of the container but the lower flange of the I ring 0, and the ring seat or annular groove for the reception of the parts 9', it and of the edge of the cover f is formed exclusively by the ring 0'; in other words, the ring seat is formed by a single member.
Fig. 4t shows another construction in which the ring seat is formed by a single member 0 the outer periphery of which is of circular curvature, as shown, and the inner surface of which has a seat 0 for the cover and a groove 0* for the expanding ring or equivalent locking means. The smooth end portion of the body is of substantially semi-circular curvature in cross-section to fit around the correspondingly curved outer surface of the ring 0 In Fig. 5, as 1n Fig. l, the ring surrounds the smooth end portion of the containerbody. Said end portion 6 is partly fiat to form a seat for the packing g and partly round, as shown, to lie within the curved portion of the surrounding ring 0 While in Fig. l the flat portion of the container body engaged by the packing g is substantially unsupported by the surrounding ring, according to Fig. 5 the ring is extended at c to support the corresponding portion of the smooth container end at every point, and furthermore said ring is formed with a downward extension or flange c which fits against the ends of the corrugations of the container body whereby the ring 0 is given a firm support during the operation of molding the smooth end portion of the container body into said ring.
It will be understood that the smooth portion of the container body is to be given the more or less angular or profiled section illustrated, by the same pressure and drawing operation which smooths outsaid portion, it being understood that originally the corrugations extend to the very edge of the container'body and are smoothed or flattened out by an operation combining pressure and drawing. The smooth portion of the'container might be given this profiled form first, and the ring 0, c, c or o subsequently placed around or into the profiled portion of the container end. However, I prefer to use the said ring a, c, c or c as a mold or die against which the edge portion of the container body is forced, during the operation combining the pressure and drawing which smooths out the corrugations in said edge or end portion. so that there will be effected at the same time the following three steps or operations:
1. The smoothing out of the corrugations on the end portion of the container body.
2. The giving of a profiled section to such end portion.
3. The securing of a connection of such profiled portion with the correspondingly shaped annular surface of the ring a, c c or c, said ring together with-said profiled neaenee portion forming the ring seat for the reception of the container cover, the packing and the locking means.
Various changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of my invention.
