page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of July, in the year of our Lord
One thousand eight hundred and sixty. in the twenty-fourth year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me,
the said John William Edge, Her special licence that I, the said John William
Edge, my executors, administrators, and assigns, or such others as I, the
said John William Edge, 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 "IMPROVE-
MENTS IN RIFLED FIRE-ARMS, GUNS, AND ORDNANCE," upon the condition (amongst
others) that I, the said John William Edge, my executors or administrators, by
an instrument in writing under my, or their, or one 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 John William Edge, do hereby declare
the nature of my said Invention, and the manner in which the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say):-
My Invention consists in giving an improved form or shape to the grooves
cut in the bores of rifled fire-arms, guns, or ordnance. Instead of the rect-
angular grooves as at present adopted, I make them with sides having obtuse
angles with each other, or with sides of a curved shape.
The manner in which my Invention is to be performed will be clearly
understood by referring to the figures and letters on the accompanying Sheet of
Drawings, in which Figures 1, 2, and 3, are transverse sections of rifled gun
barrels in which the grooves are obtuse-angled, and Figure 4, an enlarged view
of one of the sections; Figs. 5, 6, and 7 are transverse section of other
rifled gun barrels having the grooves formed with curved sides, and Figure 8,
an enlarged view.
In Figures 1, 2, 3, and 4, the grooves are shewn at a; they are formed of
three obtuse-angled sides; which angles may be varied to any degree. In
Figures 5, 6, 7, and 8, the grooves are shewn at b; they are formed with two
curved sides and one flat, but this form may be modified by making the three
sides curved, the radii of the curves being varied as required.
Having now described the nature of my said Invention, and the manner

page_text: in which the same is to be performed, I desire it to be distinctly understood
that I claim as my Invention, and which to the best of my knowledge and
belief has not been hitherto used within the realm in the manufacture of rifled
fire-arms, guns, and ordnance, grooves of three sides at obtuse angles with
each other, or with curved sides, as herein described and illustrated in the
accompanying Sheet of Drawings.
In witness whereof, I, the said John William Edge, have hereunto set my
hand and seal, this Tenth day of January, in the year of our Lord One
thousand eight hundred and sixty-one.
Signed, sealed, and delivered by the within-
named John William Edge in the pre-
sence of
E. J. HUGHES, Patent Agent,
Manchester.
