‘V the tap
buShi'n‘g‘I-Z' and bung bushing l6 mechanically in
terconnect the inner and outer shells at two
points and'thereby tend to maintain'the‘ same
in proper spaced relation. In this action these
bushings are aided by the insulations H andI.
In-some instances; however, the inner shell shifts
or tends to' shift with respect tothe 'outer shell
and where shifting occurs stress is built up at
thetwo‘ points where the inner shell is secured
to the outer shell, namely, in the region ofr'th'e
tap and bung bushings. This concentration of
55 stress may result in fracturing either the‘ welds or
the inner shell at or near either one ‘of these two
points. ' Thereupon le'akageof the contents will
take place between thej'inne'r’ and'out‘e'r shells- and
the container is rendered un?t for use. '
60 ‘The present invention proposes to preclude any
such concentration of stresvs'and consequent frac
turing and leakage and accomplishes ‘this by pro‘
viding means ‘which‘coacts with the bung and tap
permit of the hanging up of the portion 32 of the
upper end head 4 ofTthe inner shell S, as illus
trated in Figure 5. The portion 32, which is the
marginal portion of the opening provided in the 40
upper head 4 for the’ tap bushing, is then welded
to‘the tap bushing'as indicated at 33. The outer
peripheryof the'inner end of the bushing is also
welded to the upper end head 4 of the inner shell
as indicated at'33’. As in the other embodiment
of the invention, a protective ringror annulus of
metal designated‘ at IT is provided in order to
protect the weld 33" during the formation of the
weld l8 between the portion‘ H! of the upper end
head of the outer shell or jacket J and the inter
mediate portion of the bushing’ 30.

indicated at‘ 43'.’ The outer end portion of the
circular plate 20 which is of approximately the
bushing ‘is received'in an opening in the outer
shell or jacket J, which opening is designated at
44v and indicated in dotted'linesinFigure 9. The
portion of the outer‘ shell surrounding’ the outer
end of the bushing is displaced inwardly slightly

~ In effecting this threeépoint suspension a steel

diameter is punched or drilled in the outer shell

While’I have shown and described several con
structions in which the invention may be advan
tageously embodied, it ‘is to be understood that
these constructions have been selected merely for
the purpose of illustration or example, and that
various changes in the size, shape and arrange
ment of the parts may be made without departing
from the spirit of the invention or the scope of
the subjoined claims.
The invention claimed is:
1. A container of the character described com
prising inner and outer shells, the inner and out
er shells being made up of tub-like sections weld
ed together in the assembly, a tap bushing weld
‘ed to the upper end heads of the inner and outer
shells, a hung bushing weldedto the body por
tions of the inner and router shells, a plate weld
ed to the lower end head of the inner shell in ver
tical alinement with the tap bushing, the lower
end head of the outer shell having an opening
underlying said plate and a Weld between the
margin of the opening and said plate.
2. A metal container of the character de
scribed comprising inner and outer shells, means
for securing the shells in spaced relation and an
auxiliary support and connection between the
shells comprising a plate welded to the inner shell,
the outer shell having an opening overlying the 10
plate, and a weld between the margin of said
opening and said plate.
