PROCESS OE MAKING BARRELS.
Specification of Letters Patent.
Patented Apr. i6, 191B.
Original application led March 10,r 1911, Serial No. 613,589. Divided and this application filed May 23, 1914. Serial No. 840,421.
g.[S`his invention relates to pressed metal barrels, and has for its object to provide a process whereby barrels of this kind may be constructed which shall be composed of the smallest possible number of parts and capable of production with the smallest possible number of operations consistent with strength; also to roduce a barrel having 'the smallest possi le number of joints or seams through which leakage may occur; also to produce a barrel which shall possess great strength at lthe points where strength 1s most needed and to secure such strength although the barrel may be made from thinner and lighter,l metal than has heretofore been employed.
In the drawings forming part hereof, Figure 1 is a vertical sectional view of a barrel made in accordance with my invention and showing the barrel head applied, but not secured in place; Fig. 2 is a detail sectional view illustrating the manner of securing the inserted head to the barrel; Fig. 3 is a similar view o f the lower end of the barrel; Fig.4 is a sectional detail of the lower end of the barrel showing in dotted lines the position of the bottom or fixed head and ody of the barrel and in full lines the position of the body and bottom after the first step in forming the bottom chime; and Fig. 5 is a transverse sectional view of a-portion of the barrel body.
The barrel body is preferably composed of a single piece of metal, and is made by pressing a at sheet of metal into the form of a cylinder having one end closed. In forming the lower end of the barrel, the bottom or fixed head 1 is pressed into the cylindrical blank, leaving a depending cylindrical skirt formed of the doubled metal, as shown 4at 2, in Fig. 4. For the purpose of providing a chime of suiiicient strength as well as for the purpose of re# inforcing the bottom, this skirt is then rolled inwardly and preferably into contact with the bottom l, thus forming a rounded chime 2a, the eXtreme end portion l2b of which abuts against the bottom head, the bottom and the chime thus strengthening each other through their inter-engagement.
The sides of the cylindrical blank are next pressed outwardly between suitable dies, so as to form the flaring or bilged body 3 of the barrel, the dies being so constructed as to form at the same operation the longitudinal stiffening corrugations et in such body.
The barrel head is made in the form of a flat circular plate 6 having an annular rim 7 turned inwardly at an acute angle, and the total diameter of said head is such as to permit it to be inserted within the c lindrical neck or extension 5 and to be seated upon the ends of the corrugations 4f.
A ring 8, preferably of Norway iron, is now placed in the trough formed between the rim 7 and the neck or extension 5`. When the metal is inserted into this trough, heat .is applied to fuse the metal and to produce a closed joint at the bottom of the trough by the so-called rocess of autogenous welding, after which the neck or extension will be forced inwardly intov parallelism with the rim 7 and in contact therewith, after which the two thicknesses of metal are rolled inwardly to form a rounded chime, as shown at 9. The edges of the two thicknesses are preferably bent into engagement with the head, as shown at 10, thus vreenforcing the head and the edge of the chime by the inter-engagement of one with the other. As will appear more particularly from Fig. 2, the lower' ends of the overlapping thicknesses or plies of metal are directed outwardly, as shown at 11, whereby, should the head 6 fail for any reason to be properly supported by the internal seat, it will be supported against inward movement bythe overlapping 'end of the neck or barrel extension. While I prefer to use Norway iron for the ring which is to be inserted in the trough between the neck 5 and rim 7, it is evident that other suitable material may be used, such as solder or fusible wire.
The two. chimes formed at the opposite ends of the barrel are of substantially the same shape, thus rendering the barrel symlnetrical in construction and appearance; at the ends both chimes engage their corresponding head in a circular line which is located within and at adistance from the adjacent end of the barrel body and the outer peripheral portion of the head.
The connstruction above described is particularly advantageous in that it permitsy the use of unusually thin metal without decreasingdetrimentally the stii'ness or strength of the barrel. rlhe thickness of metal which can be employed is about sixone hundredths of an inch. rllhe formation of the chimes in the manner described gives them suiicient strength to withstand all ordinary incidents of use and their engage nient with the heads in the manner described so renforces these heads as to enable them to carry the weight of the material within the barrel. Although ll have described my barrel as made by pressing a latsheet, it is obvious that many of the advantages thereof could be obtained by rolling an elongated strip of metal into a cylindrical form and brazing, welding, or
riveting the ends together. All these, and other modifications ll consider within the scope of my invention, excepting as limited by the prior state of the artv and by the terms of the claims hereto annexed.l
The subject matter of this application constitutes a division of my prior application No. 613,589, filed March 10, 1911, and patented April 16, 1918, No. 1,262,766.
Having thus described my invention, what I claim is Y 1. The process of making a metallic barrel which comprises applying to an end of a hollowl metal body a head having an outwardly projecting iange, uniting said ange and the adjacent end portion of said body, and forcing inwardly the double wall of metal to produce a chime.
2. rlhe process of making a metallic barrel which comprises seating within the open end of a hollow body a head having an outwardly projecting ange, welding said ange to the adjacent end portion of said body, and forcing inwardly the double wall of metal to produce a chime.
3. rlhe process of making a metallic barrel which comprises forming a hollow body having a closed end, telescoping such end naoaeee -pressing such closed end inwardly to provide a cylindrical skirt of doubled metal rojecting beyond a head, and forcing the said skirt inwardly and into substantial engagement with such head.
5. 'llhe process of making a barrel body which comprises drawing a metal plate into the form of a receptacle having a closed end, pressing such end inwardly thereby to provide a skirt of doubled metal projecting beyond a head, 'and forcing said skirt inwardly and into engagement with the said head with the line of engagement within and at a substantial distance from the periphery of such head.
6. The process of making a metallic barrel which comprises forming a hollow body having a closed end, pressing said closed end inwardly thereb to provide a skirt :formed of doubled meta projecting beyond a head, forcing said skirt inwardly to provide a chime of such doubled metal, inserting within the open end `of the said body a head having an outwardly, projecting iange, and 'forcing said iange and the adjacent end portion of the body inwardly thereby to form a double walled chime complementary to and symmetrical with the chime at the opposite end of said body.
7. 'llhe process of making a metallic barrel which comprises forming a hollow body hav.- ing a closed end, pressing said closed end inwardly thereby to provide a skirt formed of doubled metal projecting beyond a head, forcing said skirt inwardly to provide a chime of such doubled metal, applying to the open end of said barrel a head having an outwardly extending flange, and forcing said flange inward-ly toward the head thereof.
lln testimony whereof, ll hereunto affix my signature in the presence of two witnesses.
