Improvements in Metallic Packages or Containers and Method of
Making the same.
A communication by CHARLES LEWIS COFFIN, of 980, Jefferson Avenue,
Detroit, in the County of Wayne and State of Michigan, United States of
America, Chemist.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.1.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention consists in an improvement in method of making a metal package,
and in the package itself. It will be understood from the following description,
reference being had to the accompanying drawings.—
Figure 1 is an elevation of the improved package;
Figure 2 a vertical central section therethrough;
Figures 3 and 4 diagrams of the shell before and after beading;
Figure 5 a section through one end of the shell, showing the head in position
before beading; and
Figure 6 is a similar section showing the head beaded in.
The improved package consists of a shell S, having flanged heads C and hollow
boops H H', and is made as follows:-A plate of metal is rolled into a cylinder S,
and the longitudinal seam welded so as to form a complete cylinder. Upon this
cylinder are shrunk hollow hoops H, provided with flanges h, which perform the
double purpose of strengthening the cylinder, and forming a bilge or ways for the
cylinder to rest and roll upon. Around the cylinder, at each end, a bead 8 is rolled
and into the end of the cylinder is inserted a head C, formed with a flange c, as
shown in Figure 5. The flange c of head C is then beaded into bead b, for the
purpose of securing it and the cylinder together, and then the flange c welded to
the shell S, thus securing head Ć permanently in place and making a tight joint
between the head and shell, and both heads are put in in the same manner.
One of the heads may be put in place before the hoops H H¹ are shrunk on
but it is preferable not to put in both heads before the shrinking.on of the hoops,
as the hoops may be made to fit tighter to the shell if they are not required to pass
over the bead b. For the purpose of strengthening the chime, a beaded hoop J J¹
may be shrunk on at each end, its head being made to fit the bead b. B represents
a bung which is secured to shell S either by riveting or welding, preferably by
welding, either between the two hoops H H¹, or if preferred it may be placed in
one of the heads C:
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. The method of manufacturing a hollow package or container consisting in
first welding the longitudinal seam of the shell then beading the shell at the end,
inserting a flanged head, and beading the flange down into the bead of the shell,
then welding the flange joint to the shell.
2. As a new article of manufacture, a hollow metal package or container con-
sisting of a cylindrical shell, having a longitudinal welded seam, flanged heads
welded therein, and hollow bilge hoops.

page_text: 3. In a hollow metallic package or container the combination of a longitudinally
welded cylindrical shell, circumferentially beaded at the end, a flanged head welded
to said shell, and a chime hoop engaging the bead in the shell.
4. In a hollow metallic package or container, the combination of a longitudinally
welded cylindrical shell circumferentially beaded at the end and a flanged
head. welded to said shell, with a hollow bilge hoop and a chime hoop engaging
the bead in the shell.
5. In a hollow metallic package or container, the combination of a longitudinally
welded cylindrical shell circumferentially beaded at the end and a flanged head
welded to said shell, with a chime hoop engaging the head in the shell, a hollow
bilge hoop, and a bung for filling or emptying said container.
