METAL BARREL F'iled Aug. 9, 1935 INVENTOR. CZdr/as H M dman ATTORNEYS.

Patented Dec. 8 1936 UNITED STATES PATENT OFFICE METAL BARREL ration of Delaware Application August 9, 1933, Serial No. 684,293

4 Claims.

My inventionrelates to the construction of metal barrels, particularly those comprising an inner fluid container and an outer reinforcing and insulating shell.

One object of my invention is to provide an improvement upon the metal barrel construction disclosed in the co-pending application of- Clar ence W. Avery, Serial No. 673,762, filed May 31, 1933, and the co-pending application of James Vehko, Serial No. 684,325, filed August 9, 1933, the said Avery and Vehko applications each disclose a construction in which the inner container of the barrel is composed of two like cup or pot shaped parts joined together by outwardly extending flanges. at their open ends, and the outer shell is likewise composed .of twolike cup or pot shaped parts, the edges of which around the open ends are joined together and to the inner container at the outwardly extending flanges provided upon the inner container.

My improvement comprises generally the provision of irregular flanges about the open ends of the inner container, that is the flanges extend outwardly a greater distance at spaced points. providing outwardly extending spaced lugs to which the edges of the outer shell parts may be secured for the purpose of securing the outer shell to the inner container, and providing spaces between these outwardly extending lugs in which heat insulating material may be placed, or which may beleft as dead air space, to prevent heat conduction from the inner container, to the outer shell and vice versa.

My improved construction provides a more completely insulated barrel than that disclosed in the above mentioned co-pending applications of Clarence "W. Avery and James Vehko.

For a better understanding of the invention, reference may now be had to the accompanying drawing, in which:

Figure 1 is a vertical cross-sectional view of a metal barrel embodying my invention.

Fig. 2 is a horizontal cross-sectional view taken on line 2--2 of Fig. 1.

Fig. 3 is a sectional view taken on line 3-4 of Fig. 2.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 2.

Fig. 5 is a sectional view illustrating a modification of the joint illustrated in Figs. 3 and 4 between the parts of the outer shell and the inner container.

Fig.6 is a fragmentary elevational view of the central portion of the barrel showing the two parts of the inner container assembled together and the two parts of the outer shell separated to.

better illustrate my improved construction.

The barrel comprises generally an inner container l composed of two like parts 2 and 3 which are generally pot shaped having closed ends and 5 having. outwardly extending flanges 4 formed around their open ends. The flanges i of one part are adapted to mate with like flanges 4 on the other part and to be secured to each other by welding or other similar means to provide a o fluid tight joint around the central circumferential part of the inner container. The outer shell is composed of two like parts 5 and 6 also generally pot shaped and provided with offset portions 11 which provide reinforcement and 1e chime portions 8 around their closed ends. A tap bushing ii is provided at the top of the barrel and is secured in registering openings of both the inner container and outer shell, and a hung bushing it is positioned in the central part of the barrel and is likewise secured to both the inner" container and the outer shell around registering openings therein.

My improved construction consists in providing outwardly extending lugs ill on the flanges d 25 formed around the open ends of the parts 2 and hot the inner container. These lugs it are provided at spaced points. The parts 2 and 3 of the inner container are secured together with their flanges i in contact and with the lugs ill on each my part registering and in contact with the lugs ii on the other part. The flanges i are then secured to one another to form a fluid tight joint by welding or other similar suitable means, the

weld being made along a line near the base of the 35 flanges t and inwardly of the lugs ll 1|.

The outer shells t and ti may be provided at their open ends with outwardly directed flanges Ii, if desired, or such flanges may be eliminated and the edges of the shells left straight as shown no in Fig. 5;. The edges of the outer shells however are in any event provided with notches l3 to fit around the outwardly extending lugs ii on the inner container, in order that the edges of the shells 5 and 6 between the lugs I [may be brought 45 into abutting contact with one another. The notches it are so proportioned as to bring the edges of the outer shells at these points in abuttingrelation with the sides and edges of the lugs II on the inner shell. If desiiedi'the-notches I3 50 may be formed entirely in one ;of the outer shell parts 5 or 6 by making the shell part which contains the notches slightly longer than the other shell part.

The parts 5 and 6 of the outer shell are applied 55 to the inner container by placing them over opposite ends of the inner container and bringing edges of their open ends together in the region of the central flange 4 on the inner container. The notches l3 in the edges of the outer shells permit the lugs II on the flanges of the inner container to project to the exterior of the outer shell and also permits the edges of the outer shell between these notches to come into abutting contact with one another. When this assembly has been made, the edges of the outer shells 5 and 6 are welded at the notches l3 to the ends of the outwardly extending lugs l l on the inner container, which are welded together in the same operation, and the abutting edges of the outer shells between the notches I3 are welded to one another.

This provides a construction in which spaces are provided between the inner container and the outer shell between the lugs H in which heat insulating material may be placed to more completely insulate the inner container from the outer shell, or a dead air space left for insulating purposes, the only heat conducting metal contact between the inner container and the outer shell in the region of joinder being through the spaced lugs ll.

Formal changes may be made in the specific embodiment of the invention described without departing from the spirit and substance of the broad invention, the scope of which is commensurate with the appended claims.

I claim:

1. A metal barrel comprising a fluid container composed of a pair of like parts each having a continuous outwardly extending flange at its open end, said flanges having spaced outwardly extending lug portions and said flanges being welded to each other to provide a fluid tight joint between said parts, an outer shell comprising two like parts adapted to flt over said inner container in spaced relation thereto and having their edges at their open ends abutting said lugs on the flanges of said inner container at a point spaced outwardly from the edges of said flanges between said lugs, said edges of said outer shell parts and the lugs on said flanges of said inner container all being secured together for securing said outer shell parts together and to said inner container.

2. A metal barrel comprising a fluid container composed of a pair or like parts each having a open ends abutting said lugs on the flanges of said inner container at a point spaced outwardly from the edges of said flanges between said lugs, and said edges of said outer parts abutting each other between said lugs on said inner container, said edges of said outer shell parts and the lugs on said flanges of said inner container being secured together and the edges of said outer shell parts being secured together between said lugs, for securing said outer shell parts together and to said inner container.

3. A metal barrel comprising a pair of pot shaped sections flanged in their marginal edges and secured together through said flanges to provide a closed inner container, circumferentially spaced projections on said flanges, and a second pair of similarly shaped pot shaped members also flanged in their marginal edges, the flanges on said second pair of pot shaped members-having mating recesses adapted to receive the projections on said first mentioned flanges, said second pair of pot shaped members being secured together through said flanges and secured to said projections, said second pair of pot shaped members being rigidly retained in predetermined spaced relation to said first pair of pot shaped members by said projections.

4. A metal barrel comprising a pair of pot shaped sections flanged in their marginal edges and secured together through said flanges to provide a closed liquid container, circumferentially spaced projections on said flanges and a second pair of similar pot shaped members also flanged in their marginal edges and adapted to be secured together, recesses between the mating flanges of said second pair of pot shaped members adapted to receive said circumferentially spaced projections whereby said second pair of pot shaped members may be secured together and secured to said projections, said second pair of pot shaped members being rigidly retained in predetermined spaced relation to said first pair of pot shaped members by said projections.
