PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metal Barrels and other like
Vessels.
I, DAVID CAIRD of 3 Crown Court, Old Broad Street, in the City of
London, Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to the manufacture of metal barrels and other like
vessels in halves or parts in the manner described in my Specification No. 13,373
of 1891, the said halves or parts being then so connected together that a liquid tight
joint is formed between them.
According to my present invention I connect the halves or parts of the vessel
together by seaming and this may be effected as follows:-I first form an out
turned flange at the edge of each half or part barrel and a groove around the
periphery of the same at a short distance from the edge. The flange on the one
half-barrel is wider than that on the other half-barrel. The wider flange is folded
over the edge of the narrow flange and then doubled over behind this flange, the
two flanges being well pressed together; the joint thus formed may be brazed or
soldered if desired. To make a more perfect joint the two flanges may receive one
or more additional folds.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metal Barrels and other like
Vessels.
I, DAVID CAIRD of 3 Crown Court, Old Broad Street in the City of
London, Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My invention has reference to the manufacture of metal barrels and other like
vessels in halves or parts in the manner described in my Specification No. 13373
of 1891 the said halves or parts being then so connected together that a liquid-tight
joint is formed between them.
According to my present invention I connect the halves or parts of the vessel
together by seaming and this I may effect as follows:-I first form an out-turned
flange at the edge of each half or part barrel and a groove around the periphery of
the same at a short distance from the edge. The flange on the one half barrel is
wider than that on the other half barrel. The wider flange is folded over the edge
of the narrow flange and then doubled over behind this flange, the two flanges being
well pressed together. The joint thus formed lies within the grooves above
described and is somewhat below or under the bilge or belly of the barrel; it may
be welded, brazed or soldered if desired.
The manner of carrying out my invention is illustrated in the accompanying
drawings.
Figure 1 represents diagrammatically a finislied barrel in longitudinal section.
This barrel is formed of two parts each of which comprises one head or end a and
one half of the body, these parts being drawn or stamped out of circular sheets or
blanks of metal as described in my said former Specification. They are then, after

page_text: trimming, connected together at c. The mode in which the connection is effected is
illustrated in Figures 2, 3 and 4 and is as follows:-Upon one of the halves of
the barrel body I form an out-turned flange cand a circumferential groove d and
upon the other half I also form an-out-turned flange and a grooved but the
flange e is wider than the flange c¹ (see Figure 2). I then fold the flange c over the
flange c¹ (see Figure 3) and next double it over behind the flange c¹ (see Figure 4)
the two flanges being well pressed together. The two halves are thus securely and
hermetically connected together and the joint lies within the grooves dd and is
slightly below the bilge or belly of the barrel so that it is not subject to undue
The joint has also the effect of strengthening the body of the barrel. The
folding and doubling are effected by means of tools such as are used in "scaming'
as will be well understood.
wear.

When, as in the case of a comparatively large barrel, it is not convenient to make
the barrel in only two pieces I can make it in four or other number of pieces or
sections as shown in Figure 5 which shows a barrel made up of four sections the
two outer sections each comprising a head or end a and part of the body and the
two middle sections being part of the body. All the parts or sections are
flanged and connected together in the manner hereinbefore described.
"
The invention applies to the manufacture of metal vessels of cylindrical form
such for example as "drums as well as to vessels having a bilge or belly such as
those shown in the drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In the manufacture of metal barrels and other like vessels which are made up of
halves or sections, the mode or method herein before described of connecting
together the said halves or sections which consists in flanging and circumferentially
grooving them and then uniting the flanges by seaming in such manner that the
joint thereby formed lies within the grooves and below the bilge or belly of the
vessel, all substantially as herein before set forth.
