PROVISIONAL SPECIFICATION.
Improvements in Metallic Casks.
We, WILHELM KOLLMANN and WILHELM FROEHLICH, both of Schwieutochlowitz
Upper Silesia, Germany, engineers do hereby declare the nature of this invention to
be as follows:-
Our invention relates to an improved means of fastening the heads in metallic
casks, especially in those casks which are used for the transport of cement and other
dry material, and consists of a number of clips fastened to the head of the barrel and
bent over the rim of the cask which is formed with a bead for this purpose, or the
clips may also be fastened to the outside of the barrel itself near the top and bent
over the edge of the head.
This manner of holding the heads in the barrels, although easily unfastened, holds
the end perfectly secure during transport or rough usage and offers many advantages
over the usual wooden barrel in general use till now. The top of the barrel is
formed into a "bead" with a stiff wire core in order to offer a sufficient grip for the
clips, but it is not absolutely necessary that there should be a wire core in the
"bead" or rim but the end of the metal itself may be folded round sufficiently so as
to form a rim of the required resistance round which to bend the clips.
By the use of our improved means of fastening the heads can be quickly and
securely fastened in the barrels without the use of complicated tools and as easily
opened.
In order to make our invention more clear, we refer to the accompanying drawing
in which similar letters denote similar parts throughout the different figures.
Fig. 1 shows a sectional view of a complete cask without the fastening clips:
Fig. 2 is a top view of fig. 1.
Fig. 3 and 4 show parts of the cask and head in larger scale.
Figs. 5, 6 and 7 show different forms of clips.
Fig. 8 shows parts of the cask, head and stiffening ring full size.
Fig. 9 shows a modified form of stiffening ring, which is formed by the metal of
the cask itself.
The cask m is made from corrugated iron with a bottom 6 of any convenient
construction is provided with a stiffening ring at the top.
The head d is provided with a groove n which fits over the ring r so that there are
two bearing points a and ẞ all round; the head is made tight by clips e which
surround the bent part n of the head and the clips are pressed together by a pair of
pliers so as to press the two surfaces a and ẞ hard against the ring r of the cask; a
sufficient number of these clips e are placed round the circumference and hold the head
tight enough to prevent any loss of material from the cask as the ring n on account of
its elasticity bears all the way round.
There are three different forms of clips shown; that shown in fig. 5, is a simple
C-shaped clip the ends of which are simply pressed together over the rim of the cask.
That shown in fig. 6 is made with an extension o, which lies on the cask head, under
which a bar or chisel is forced in order to remove the clip; the third modification
shown in fig. 7 is fitted with a second extension which lies against the side of the
cask and protects the cask from the sharp end of the clip when the extension o is
forced up.

purpose substantially as described.

formed round its rim, the bead containing stiffening ring r, and with clips e having
elongation lying over cask head, in the manner substantially as described.
3.) The combination of the head d having groove n, with the cask m having a béad
formed round its rim, the bead containing stiffening ring r, and with clips e having
elongation lying over cask head and having elongation i coming against the barrel
of cask, in the manner and for the purpose, substantially as described.
4.) The combination of the head d having groove n, with cask m having a doubly
rolled bead round its rim and with clips e, for the purpose substantially as described.
