Year: 1869

page_text: LETTERS PATENT to Edmund Haviland Burke, of No. 5, King's
Bench Walk, Temple, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN METALLIC BARRELS,"
Sealed the 24th May 1870, and dated the 26th November 1869.
PROVISIONAL SPECIFICATION left by the said Edmund Haviland
Burke at the Office of the Commissioners of Patents, with his
Petition, on the 26th November 1869.
I, EDMUND HAVILAND BURKE, of No. 5, King's Bench Walk, Temple,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN METALLIC BARRELS," to be as follows:-
This Invention has mainly for its object to construct metallic barrels
suitable for containing beer, wine, explosive, and combustible liquids.
For this purpose I form the body of the barrel from a plate of iron bent
to a cylindrical shape and welded up to form a tube. Each head of the
[Prios 8d.]

page_text: cask I make of a disc of iron with a cylindrical flange passing around
it which just fits into the body of the barrel, and I weld this flange all
round to the edges of the cylinder. By this means I obtain a metallic
barrel with welded joints throughout. In some cases I coat the interior
of the barrel with enamel, glass, porcelain, or earthenware and to increase
the holding of the enamel, glass, porcelain, or earthenware on the
surface of the metal I form the surfaces which are to be coated with
numerous grooves or small corrugations.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edmund Haviland Burke in the Great Seal
Patent Office on the 26th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, EDMUND
HAVILAND BURKE, of No. 5, King's Bench Walk, Temple, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of November, in the
year of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edmund Haviland Burke, Her special
licence that I, the said Edmund Haviland Burke, my executors, admi-
nistrators, and assigns, or such others as 1, the said Edmund Haviland
Burke, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and venil, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE.
MENTS IN METALLIC BARRELS," upon the condition (amongst others) that
1, the said Edmund Haviland Burke, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said Edmund Haviland Burke, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
This Invention has mainly for its object to construct metallic barrels
suitable for containing beer, wine, or explosive or combustible liquids.
For this purpose I form the body of the barrel from a plate of iron bent
to a cylindrical shape and welded up to form a tube. Each head of the
cask I make of a disc of iron with a cylindrical flange passing around
it which just fits into the body of the barrel, and I weld this flange all
round to the edges of the cylinder. By this means I obtain a metallic
barrel with welded joints throughout. The requisite opening or bung
hole is formed in one of the heads previous to its being welded up into
the cask.
In the Drawing hereunto annexed is shown a longitudinal section of
a metallic barrel constructed as above described. Any suitable means
may be adopted for welding the flange which passes around each head
of the barrel to the body; they may simultaneously and whilst held
together be brought to a welding heat by jets of flame directed against
the parts to be welded, the whole flange of a head and the end of the
cylindrical body being thus brought to the requisite heat by keeping
them turning round so that the jets shall act equally on all parts of the
flange and the end of the body. When each part has thus been brought to
the requisite heat a small amount of sand is thrown, as is usual, on to
the parts which are to be welded together, and the head is then at once
welded into the body by hammering or rolling. To facilitate the sand
or slag formed from it running between the parts to be welded together
the flange around the head may be set to project slightly beyond the
body, so that the sand may rest upon it and run in between the parts
to be welded; or for the same purpose the body might project slightly
beyond the flange; the flange might also, if desired, be very slightly set
inwards so as to appear thus L
; this also would facilitate the
After cach
introduction of the sand between the parts to be welded.
head has thus been welded into the body the interior of the barrel may
be coated with glass, porcelain, or earthenware, or in some
desired the interior of the cask might be coated with tin or zinc, and
this might be readily effected in the manner described in the Speci-
cases if
