BARREL.

Application filed March 28, 1924. Serial No. 702,634.

. One object of my invention is to improve the construction of barrels having a body portion of metal and provided wit wooden heads.

A further object of the invention is to design the barrel so that it will not be deformed, or collapsed, when rolled on its lower edge, due to weight of its contents.

A still further object of the invention is to design the body of the barrel so that a com arativel light head can be used.

, T e barre is intended, primarily, for shipping lime and like material, but it will be understood that it can be used for shipping any material without departing from the essential features of the invention.

In the accom anying drawings: Fig. 1 is a vertical sectional view of the completed barrel; Fig. 2 is a vertical sectional view of the barrel illustrating the process of forming the supporting annular ribs for the heads and securing one head to the barrel; Fi 3 is an enlarged sectional view of one en of the barrel, showin an annular rib prior to bein bent into al shape; Fig.

4 is a view .,s owing a rib bent into final shape; and Fig. 5 is a sectional view of the lower portion of a barrel.

Referring to the drawings, 1 is the body of a barrel made in accordance with my invention and corrugated in the resent instance. A plain cylindrical-b0 y may be used, if desired. Near each end of the barrel is a deep, internal annular rib 3. These internal ribs sup ort the heads 4:, of the barrel, which, in t e present instance, are of wood and generall consist of a number of pieces. The woo en heads fit the flanges 5 at the ends of the barrel. The flanges are of a greater depth thanthe thickness of the heads so that a head-when in ositionas in Fig. 2, is below the end 0 a flange,

and, when the. flange is turned over, as

shown in Fig. 1, the head is held-firmly between the annular rib 3 and the turned over flange.

In making the metallic body of a barrel,

the ribs are partly formed, as in Figs. 2 and- 3, by making anannular depression 2 in the body near \,each end thereof. When pressure is applied, the outer edge 6 of the internal flange is flattened to receive a head of the barrel. The other portion of the rib is curved, as shown clearly in Fig. 4, so that the outer edge 7 bears against the outer edge of the portion 6, supporting rigidly with the body portion thereof resting upon the back of a flange. It will be observed that the loop 3 servesnot only to preventthe bending of the head and the crushing of the body but also serves to directly carry a part of the superposed load and thus reduce the strain on the head. It will be further observed that the face of the rib which en ages the head is wide and flat, thus providing extended contact with the head, and

that the inward turned part of the flange 5 is also wide and flat thus firml engaging the outer surface of the barrel 'a jacent the entireperipheriy thereof. Inasmuch as the head is griptpe between two flat faces it is greatly rein orced and the danger of breakage is practically eliminated.

In assembling a barrel, one flan ed end is placed over a form 9, Fig. 2, an a head 4 is placed in the opposite end of the body of the barrel. and rests upon the partially formed rib 3 at the upper end of the body of the barrel. The lower partially formed flange 3 rests upon the form 9.-

T e pressure that is applied to turn in the upper flange 5 onto t e up er head of the barrel causes the partia ly formed flanges 3 at both ends of the-barrel to collapse from the position shown in Fig. 3 to that shown in Fig. 4. This rocess completes the formation of the arrel. The head that is secured to the barrel during this processis the bottom head. The opposite end of the barrel is shaped so that, when the barrel is filled, the other head can be placed in position within the flange and upon the formed internal rib, after which the flange can be turned down onto thehead.

The barrel hereinbefore described can be manufactured cheaply and the heads can be secured in position and fastened with but little effort. that although it can be made of comparatively light weight metal, on account of the which it is subjected. The construction is especialy adapted for use with wooden An additional advantage is heads, which can be secured firmly to each end of the metal body.

I claim:

1. The combination in a barrel of a sheetmetal body comprising near the respective ends thereof two deep internal integral annular ribs each in the form of an open loop having its peripheral edges in contact with each other to prevent collapsin and to reinforce the lower edge of said arrel when rolled or dropped on said edge, circular heads having their inner surfaces in enga ement with the respective ribs, and annu ar flanges formed on the outer ends of the body and bent inward to firmly enga e the outer surfaces of the respective hea s adjacent the entire peripheries thereof.

2. The combination in a barrel of a sheetmetal body comprising near the respective ends thereof two deep internal integral annular ribs each in the form of an open loop having its peripheral edges in contact with each other to prevent collapsing and to re inforce the lower edge of said barrel when rolled or dropped on said edge, the outer faces of the said ribs being flat, circular heads having their inner surfaces in engagement with the flat outer faces of the respective ribs, and annular flanges formed on the outer ends of the body and bent inward, the inner face of the said flanges being flat and in engagement with the outer surfaces of the respective heads adjacent the entire peripheries thereof.
