AN ELONGATED PRC- ⚫JECTILE TO BE SHOT FROM SMOOTH-BORED ORDNANCE, AND WHICH SHALL RETAIN DURING ITS FLIGHT THE LONGER AXIS IN THE DIRECTION OF ITS LINE OF FLIGHT TAM DA PRODELLED FROM RIFLED ORDNANCE."
Year: 1862

page_text: LETTERS PATENT to Walter Ferguson Lock, of Haylands, near Ryde, in
the Isle of Wight, Esquire, for the Invention of "AN ELONGATED PRC-
⚫JECTILE TO BE SHOT FROM SMOOTH-BORED ORDNANCE, AND WHICH SHALL RETAIN
DURING ITS FLIGHT THE LONGER AXIS IN THE DIRECTION OF ITS LINE OF FLIGHT
TAM DA PRODELLED FROM RIFLED ORDNANCE."
PROVISIONAL SPECIFICATION left by the said Walter Ferguson Lock
at the Office of the Commissioners of Patents, with his Petition, on
the 16th April 1862.
I, WALTER FERGUSON LOCK, of Haylands, near Ryde, in the Isle of Wight,
Esquire, do hereby declare the nature of the said Invention for "AN
ELONGATED PROJECTILE TO BE SHOT FROM SMOOTH-BORED ORDNANCE, AND WHICH SHALL
RETAIN DURING ITS FLIGHT THE LONGER AXIS IN THE DIRECTION OF ITS LINE OF
FLIGHT, SIMILARLY TO ELONGATED PROJECTILES PROPELLED FROM RIFLED ORDNANCE,":
to be as follows:-
The projectile consists of a cylinder surmounted by a cone, hemisphere, or
otherways shaped head forming an elongated shot, the diameter of the base or
circular section of the cylindrical part thereof shall be equal to the calibre of
the piece of smooth-bored ordnance for which it is destined, with the deduction
of the necessary windage, and the axis or length of the projectile shall be
double the calibre of the piece of ordnance from which it is sbot more or less
as convenient. The projectile retains the direction of its axis or length after
leaving the gun by means of blades or flanges inserted in longitudinal clefts
or sockets formed in the cylinder at certain intervals in greater or less number

page_text: and remaining flush with the cylindrical surface of the projectile while in the
gun, but projecting from its surface towards the base of the shot after leaving
by means of springs (which are relieved by the shot leaving the gun) or other
mechanical means. The blades or flanges work on rivets or pins towards the
front of the projectile at a greater or less distance from the front of the
projectile, the blades or flanges extending to the base of the projectile or short
of the base as may be most convenient, so as by resistance in passing through
the air to retain the projectile in its original direction. To prevent windage
and to save concussion a leaden wad attached to the base of the projectile or
detached is to be used, and with or without an iron wad; the leaden wad to
be placed over the powder, with a concave surface towards the powder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Walter Ferguson Lock in the Great Seal Patent Office on
the 16th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WALTER
FERGUSON LOCK, of Haylands, near Ryde, in the Isle of Wight, Esquire, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, 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 Walter Ferguson' Lock, Her special licence that I,, the said Walter
Ferguson Lock, my executors, administrators, and assigns, or such others as
I, the said Walter Ferguson Lock, 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 AN ELONGATED PROJECTILE TO BE SHOT PROM SMOOTH-BORED ORDNANCE, AND
WHICH SHALL RETAIN DURING ITS FLIGHT THE LONGER AXIS IN THE DIRECTION OF ITS
LINE OF FLIGHT, SIMILARLY TO ELONGATED PROJECTILES PROPELLED FROM RIFLED
ORDNANCE," upon the condition (amongst others) that I, the said Walter
Ferguson Lock, 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

page_text: Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Walter Ferguson Lock, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The projectile consists of a cylinder surmounted by a cone, hemisphere, or
otherways shaped head forming an elongated shot, the diameter of the base or
circular section of the cylindrical part thereof shall be equal to the calibre of
the piece of smooth-bored ordnance for which it is destined with the deduction
of the necessary windage. And the axis or length of the projectile shall be
double the calibre of the piece of ordnance from which it is shot, more or less
as convenient. The projectile retains the direction of its axis or length after
leaving the gun by means of blades or wings inserted in longitudinal clefts or
sockets formed in the cylinder at certain intervals in greater or less number
and remaining flush with the cylindrical surface of the projectile while in the
gun, but projecting from its surface towards the base of the shot after leaving
by means of springs (which are relieved by the shot leaving the gun) or other
mechanical means. The blades or wings work on rivets or pins towards the
front of the projectile at a greater or less distance from the front of the
projectile, the blades or wings extending to the base of the projectile or short
of the base as may be most convenient so as by resistance in passing through
the air to retain the projectile in its original direction. To prevent windage
and to save concussion a leaden wad attached to the base of the projectile or
detached is to be used. The leaden wad to be placed over the powder with a
concave surface towards the powder.
In witness whereof, I, the said Walter Ferguson Lock, have hereunto
set my hand and seal, this Fifteenth day of October, in the year of
