ANDREW DUNN and ANDREW LIDDELL,, both of 48. Long Lane Borough in the
County of Surrey "AN IMPROVED MANUFACTURE OF METAL CASKS OR DRUMS
FOR OILS AND OTHER LIQUIDS
33
The object of this invention is the construction of metal casks or drums for
containing oils and other liquids in a more economical manner than at present..
By the existing method the head or end is fitted on to the barrel portion in
conjunction with a hoop or band which has to be made separately and requires
much labour and skill to fit it in position.
Now by our Invention we dispense with the outside hoop or band and so stamp
or make the head or end itself that an overlapping edge which we form. in or from.
the flange can be set over and upon the edge of the barrel and become firmly fitted-
thereon or thereto.
We prefer to form an annular groove in the barrel near the head or end or at
both ends to give additional strength. and rigidity.

ANDREW DUNN and ANDREW LIDDELL both of 48 Long Lane Borough in the
county of Surrey AN IMPROVED MANUFACTURE OF METAL CASKS OR DRUMS FOR
OILS AND OTHER LIQUIDS.
The object of this invention is the construction of metal casks or drums for
containing oils and other liquids in a more economical manner than at present.
By the existing method the head or end is fitted on to the barrel portion in
conjunction with a hoop or band which has to be made separately and requires
much labour and skill to fit it in position.
Now by our invention we dispense with the outside hoop or band and so stamp
or make the head or end itself that an overlapping edge which we form in or from
the flange can be set over and upon the edge of the barrel and become firmly fitted
thereon or thereto.
We prefer to form an annular groove in the barrel near the head or end or at
both ends to give additional strength and rigidity
Our invention will be clearly understood by the annexed sheet of drawings in
which Figure 1 shows a drum or cask of cylindrical shape half in section and
Figure 2 the same drum in elevation from the top or head.
-
A is the barrel portion or body having an annular groove or channel B B in
it near the two ends but one cnd may be thus made if desired.
C is the bottom, dished from near the edge which is recessed at the lower
chime D and formed with a raised flange E within which the bottom end or edge
of the drum or cask barrel A is inserted and made to fit tight.
F is the head similarly dished, recessed and flanged, fitted over the top edge
of the barrel or body A said head having the filling aperture or nozzle G fitted
thereon near to the side of the same. The central portion of the head is dished
to a greater extent than that of the other dished part and a handle. His rivetted
over the smaller dish to give room for the fingers to grip the handle freely for
moving the drum about said handle being so arranged as to height as not to
interfere with the packing of one cask upon another or end to end.
When the head and bottom are in place the seams are made perfectly liquid tight
in the ordinary manner such as by solder or by tinning.
The annular groove may be dispensed with if desired whereby the barrel would
be flush for its length.
Having now.described the nature of our said invention and in what manner the
same is to be performed We declare that We claim.
The particular formation of the head, and end or one of them only recessed and
flanged within which the ends or edges of the barrel are secured in the manner and
for the purposes described and as shown in the annexed drawings.
In witness whereof we the said Andrew Dunn and Andrew Liddell have
hereunto set our hands and seals this fourth day of January in the year of our
Lord One thousand eight hundred' and eighty four.
