Year: 1854

page_text: LETTERS PATENT to John McGaffin, of Liverpool, in the County Palatine
of Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN CON-
STRUCTING AND APPLYING HEADS TO METAL CASKS AND VESSELS."
.
PROVISIONAL SPECIFICATION left by the said John McGaffin at the
Office of the Commissioners of Patents, with his Petition, on the 25th
July 1854.
I, JOHN MCGAFFIN, of Liverpool, in the County Palatine of Lancaster,
Engineer, do hereby declare the nature of the Invention for "IMPROVEMENTS. IN
CONSTRUCTING AND APPLYING HEADS TO METAL CASKS AND VESSELS" to be as
follows:-
This Invention consists of the employment of angle or curved iron rings
within the ends of casks or vessels made of corrugated iron, where the cor-
rugations run in a direction round the casks or vessels. The angle or curved
iron may be cast or wrought, and the sheet metal, forming the heads and the
sides of the cask, are fixed to the angle or curved iron by screws and nuts or
other fastenings.

by the said John McGaffin in the Great Seal Patent Office on the 11th
January 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
M GAFFIN, of Liverpool, in the County Palatine of Lancaster, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of July, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John McGaffin, Her special licence that I, the said John McGaffin,
my executors, administrators, and assigns, or such others as I, the said
John McGaffin, 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 vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
CONSTRUCTING AND APPLYING HEADS TO METAL CASKS AND VESSELS,"
upon the
condition (amongst others) that I, the said John McGaflin, by an instrument
in writing under my hand and seal, 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 Scal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John McGaffin, do hereby declaro
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 consists of the employment of angle or curved iron rings
within the ends of casks or vessels made of corrugated iron, where the cor-
rugations run in a direction around the casks or vessels. The angle or curved
iron may be cast or wrought, and the sheet metal, forming the heads and the
sides of the cask, are fixed to the angle or curved iron by screws and nuts or
other fastenings.
:
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.
Casks have before been proposed to be made of corrugated sheet iron, the
corrugations being around each cask, but there has not heretofore been a

page_text: convenient mode of fixing heads in such casks, and my improvements consist
of making and fixing internal rims of cast or wrought angle iron. For this
purpose, rings or rims of angle iron are made of sizes depending on the sizes of
the ends of the casks which are to receive them, and I fix these rims within
the ends of casks by screw bolts and nuts or by rivets, and the heads are of
plain sheet metal, which are fixed by screw bolts and nuts or by rivets to the
internal flange of the angle iron rim. If the ends of the casks are not made
cylindrical, then that portion of the angle iron rim which comes outside and
has fixed to it the corrugated iron of the cylinder is to be made of a curve to
correspond with the curvature of the corrugation at the end of a cask in which
the rim is fixed.
In witness whereof, I, the said John McGaffin, have hereunto set my
hand and seal, this Sixth day of January, in the year of our Lord
One thousand eight hundred and fifty-five.
Witness,
GEORGE ANDERSON,
Book Keeper,
Liverpool.
