Year: 1866

page_text: LETTERS PATENT to Robert Anthony Edwards Scott, of Lewisham, in
the County of Kent, Commander in the Royal Navy, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF HOLLOW PROJECTILES."
Sealed the 5th February 1867, and dated the 18th August 1866.
PROVISIONAL SPECIFICATION left by the said Robert Anthony Edwards
Scott at the Office of the Commissioners of Patents, with his Petition,
on the 18th August 1866.
I, ROBERT ANTHONY EDWARDS Scort, of Lewisham, in the County of Kent,
Commander in the Royal Navy, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF HOLLOW PROJECTILES,"
to be as follows:-
This Invention relates to an economical and easy method of manufacturing
steel shells or other hollow projectiles, and consists in drawing a steel tube
with the projecting feathers or flanges thereon which are intended to fit or
run in the grooves of the rifled gun; these feathers or flanges are drawn to
the proper spiral or twist corresponding to the rifling of the gun, and from the
tube so drawn or formed suitable short lengths to form the projectile are to be
cut off; the fore end and also the rear of the projectile are secured to the

page_text: cylindrical portion or body of the projectile by brazing or welding, or they
may be screwed in, or the ends of the projectile may be formed by upsetting
the end of the cylindrical part, leaving an opening for the introduction of the
charge; the front or fore end or other part of the shot may be tempered and
hardened so as to obtain the necessary hardness, strength, and rigidity.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Anthony Edwards Scott in the Great Seal Patent
Office on the 18th February 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
ANTHONY EDWARDS SCOTT, of Lewisham, in the County of Kent, Commander
in the Royal Navy, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of August, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her
roign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Robert Anthony Edwards Scott, Her special licence that I, the said
Robert Anthony Edwards Scott, my executors, administrators, and assigns, or
such others as I, the said Robert Anthony Edwards Scott, 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 THE MANUFACTURE OF
HOLLOW PROJECTILES," upon the condition (amongst others) that I, the said
Robert Anthony Edwards Scott, my executors or administrators, by an instru-
ment 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 Robert Anthony Edwards Scott, 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 (that is to say) :-
This Invention relates to an economical and easy method of manufacturing
steel shells or other hollow projectiles, and consists in forming such articles

page_text: from a steel or metal tube which is drawn in the ordinary manner but with
projecting feathers, ribs, or flanges thereon which correspond with and are
intended to fit or run in the grooves of the rifled gun; these feathers or
flanges are drawn on the exterior of the tube to the proper helix or twist cor-
responding to the rifling of the gun, and from the tube so drawn or formed
suitable short lengths to form the cylindrical part of the projectile are to be
cut off; the fore end, which may be pointed, and also the rear of the projectile
are made separate, and are secured to this cylindrical portion or body of the
projectile by brazing or welding; or they may be screwed into the ends of
the cylinder, or the ends of the projectile may be formed by upsetting the end
of the cylindrical part, taking care to leave an opening for the introduction
of the charge; the front or fore end or other part of the shot may if desired
be tempered and hardened so as to obtain the necessary hardness, strength,
and rigidity to sustain the blow with which the projectile will strike the object
aimed at when fired from a rifled arm.
Having now described my Invention of "Improvements in the Manu-
facture of Hollow Projectiles, and having explained the manner of carrying the
same into effect, I claim as the Invention secured to me by Letters Patent, as
aforesaid, forming shells or hollow projectiles as herein set forth from steel or
other tubes drawn with projecting feathers, ribs, or flanges thereon which fit or
correspond to the rifling of the guns in which such projectiles are intended to
be used.
In witness whereof, I, the said Robert Anthony Edwards Scott, have
hereunto set my hand and seal, the Eighteenth day of February, in
the year of our Lord One thousand eight hundred and sixty-seven.
Witness,
J. W. MOFFATT,
