ROVEMENTS IN THE MODE OF IGNITING EXPLOSIVE PROJECTILES
Year: 1863

page_text: LETTERS PATENT to Andrew Noble, of Newcastle-upon-Tyne, in the
County of Northumberland, Manufacturing Engineer, for the Invention
of IMPROVEMENTS IN THE MODE OF IGNITING EXPLOSIVE PROJECTILES."
Sealed the 31st May 1864, and dated the 24th December 1863.
PROVISIONAL SPECIFICATION left by the said Andrew Noble at the
Office of the Commissioners of Patents, with his Petition, on the
24th December 1863.
I, ANDREW NOBLE, of Newcastle-upon-Tyne, in the County of Northumber-
land, Manufacturing Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MODE OP IGNITING EXPLOSIVE PROJECTILES,"
to be as follows:-
gas
First, in throttling or contracting the passage through which the from
the burning composition escapes into the air, so as to keep up a pressure of
flame within the passage, and thereby to effect a more certain communication
of the flame to the bursting charge when the furze has burned to the point at
which it ought to fire the projectile.
Second, in introducing beneath the "pellet," which is instrumental in igniting
the fuze, a stemming of mealed powder or other combustible substance, which
on being fired by the action of the pellet shall maintain a jet of flame from the
discharging orifice sufficient to ensure the ignition of the fuze composition.
Third, in making a bend in the discharging orifice, in such a manner as to.

page_text: cause the igniting jet to be deflected at the point where it comes in contact
with the fuze composition, and thereby to cause greater certainty in igniting
the composition.
Fourth, in so forming the body of the fuze as to have solid metal instead of
fuze composition above the igniting orifice, so as to lessen the tendency to
premature explosion by the jet of flame from the igniting orifice forcing a
passage beneath the cover into the interior of the fuze.
And I hereby further declare, that these improvements are particularly
applicable to that form of time fuze which is known by the name of the
"Armstrong time fuze;" but the said improvements may also be applied to
other fuzes used in the explosion of projectiles.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Andrew Noble in the Great Seal Patent Office on.
the 10th June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
NOBLE, of Newcastle-upon-Tyne, in the County of Northumberland, Manu-
facturing Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of December, in the year of
our Lord One thousand eight hundred and sixty-three, in the twenty-seventh-
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Andrew Noble, Her special licence that I, the said Andrew
Noble, my executors, administrators, and assigns, or such others as I, the
said Andrew Noble, 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 "IM-
PROVEMENTS IN THE MODE OF IGNITING EXPLOSIVE PROJECTILES," upon the con-
dition (amongst others) that I, the said Andrew Noble, 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 Andrew Noble, 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 fol-
lowing statement:-
I, Andrew Noble, of Newcastle-upon-Tyne, in the County of Northumber-
land, Manufacturing Engineer, do hereby declare the nature of the said
Invention for improvements in the mode of igniting explosive projectiles, to be
as follows:-
First, in throttling or contracting the passage through which the gas from
the burning composition escapes into the air, so as to keep up a pressure of
flame within the passage, and thereby to effect a more certain communication
of the flame to the bursting charge when the fuze bas burned to the point at
which it ought to fire the projectile.
Second, in introducing beneath the "pellet," which is instrumental in igniting
the fuze, a stemming of mealed powder or other combustible substance, which,
on being fired by the action of the pellet, shall maintain a jet of flame from
the discharging orifice sufficient to ensure the ignition of the fuze composition.
Third, in making a bend in the discharging orifice in such a manner as to
cause the igniting jet to be deflected at the point where it comes in contact
with the fuze composition, and thereby to cause greater certainty in igniting
the composition.
Fourth, in so forming the body of the fuze as to have solid metal instead of
fuze composition above the igniting orifice, so as to lessen the tendency to
premature explosion by the jet of flame from the igniting orifice forcing a

And I hereby further declare, that these improvements are applicable to
that form of time fuze which is known by the name of the "Armstrong time
fuze;" but the said improvements may also be applied to other fuzes used in
the explosion of projectiles.
