TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
WILLIAM LANCASTER, of New Bond Street, in the County of Middlesex,
Gun Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of February, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles William Lancaster, Her special licence that I, the said
Charles William Lancaster, my executors, administrators, and assigns, or
such others as I, the said Charles William Lancaster, 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 STRENGTHENING CAST-IRON ORDNANCE," upon
the condition (amongst others) that I, the said Charles William Lancaster
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.
NOW KNOW YE, that I, the said Charles William Lancaster, do hereby
declare the nature of my 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, reference being had to the Drawing hereunto
annexed, that is to say :-
My Invention consists in removing the rear end of the gun including the
whole of the cascable before or after the gun has been strengthened with
wrought metal in the form of a hoop or hoops, jacket or jackets, or both
hoops and jackets, in forming a thread on the jacket or hoop, and in screwing
thereon or therein a wrought iron or steel breech end, or cascable, so as to
close the rear end of the gun.
The accompanying Drawing is a longitudinal section of a piece of ordnance
strengthened according to my Invention. a is the cast-iron gun from which

page_text: the original breech has been cut; b is a wrought-iron hoop surrounding the
rear end of the gun a, and extending forward somewhat beyond the trunnions.
This hoop is also prolonged to the rear beyond the point at which the cascable
has been removed, a screw thread is cut in it into which the wrought iron
or steel breech or cascable c is screwed; d, d, d, are wrought-iron hoops
surrounding the hoop b, and e is an outer jacket. Any number of hoops may
be used. Instead of the breech screwing into the hoop 6, the breech and hoop
may be made in one piece, and the hoop passed over the gun and the whole
secured by the hoops d, d, d, and outer jacket e, as before.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, strengthening
cast-iron ordnance by removing the rear end of the gun, and fitting thereto a
wrought iron or steel breech piece, or cascable, substantially in manner
herein-before described.
In witness whereof, I, the said Charles William Lancaster, have here-
unto set my hand and seal, this Thirty-first day of July, One thousand
eight hundred and sixty-two.
CHARLES W. LANCASTER. (L.S.)
