Year: 1863

page_text: LETTERS PATENT to William Palliser, Captain of Her Majesty's 18th
Regiment of Hussars, of the City of Dublin, for the Invention of "IM-
PROVEMENTS IN PROJECTILES FOR ORDNANCE."
Sealed the 24th November 1863, and dated the 27th May 1863.
PROVISIONAL SPECIFICATION left by the said William Palliser at the
Office of the Commissioners of Patents, with his Petition, on the
27th May 1863.
I, WILLIAM PALLISER, Captain of Her Majesty's 18th Regiment of Hussars,
of the City of Dublin, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PROJECTILES FOR ORDNANCE," to be as follows:-
This Invention consists in chill-casting cast-iron projectiles, either wholly
or partially, that is to say, the entire mass of iron composing the projectile
may be of chilled cast-iron, or the face or striking portion only may be chilled,
the object of which improvement being to cause so great a degree of hardness.
in the projectile as to enable it to penetrate thick armour plate.
SPECIFICATION in pursuance of the conditions of the Letters Patent,. filed.
by the said William Palliser in the Great Seal Patent Office on the
27th November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
PALLISER, Captain of Her Majesty's 18th Regiment of Hussars, of the City.
of Dublin, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Palliser, Her special licence that I, the said William Palliser,
my executors, administrators, and assigns, or such others as I, the said William
Palliser, 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 PROJECTILES FOR
ORDNANCE," upon the condition (amongst others) that I, the said William
Palliser, 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 William Palliser, 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 state-
ment:-
My Invention consists of certain improvements in the manufacture of pro-
jectiles for ordnance, the object of which is to enable them to penetrate thick
armour plate in a more efficient manner than has hitherto been accomplished
by the use of projectiles otherwise constructed.
I now proceed to describe the best means I am acquainted with for carrying
my said Invention into practical effect, as follows:-
According to this Invention, I chill cast-iron projectiles, either wholly or
partially, of whatever form they may be constructed: for example, the entire
mass of iron composing the projectile may be of chilled cast iron, or the face
or striking portion only may be chilled. I chill the shot or projectile in-
ternally, if I prefer to do so; and I also cast steel in chill for use as a pro-
jectile, and also any mixture of wrought iron and cast iron, copper and cast
iron, or other alloy of cast iron, such mixtures or alloys being cast in chill, and
used for projectiles for ordnance.
. The accompanying Drawings shew some forms of projectiles which I prefer
to use.
Fig. 1 represents a projectile with a long conical head, which I have found

page_text: in practice to be a favorable form of cone for these descriptions of projectiles.
Figs. 2 and 3 represent side views, and Fig. 4, an end view of a chisel-headed
projectile; Figs. 5 and 6, are side and end views of a projectile, double or
cross chisel edges being shewn thereon intersecting each other, and forming
the head or face of the shot; Figs. 7 and 8 shew a side and end view of a
triangular or pyramidal-headed shot; the same may also be made with
four sides.
In some cases I employ copper studded shot, as described in my Specification,
dated
I cast the copper studs in the projectiles
by inserting such studs in the moulds at the proper positions, so that they
become fixed in the surface of the projectile. If the projectile is to be used
for a breech-loading gun, it may be covered with lead in the ordinary manner;
or, for a mechanical fitting rifle gun, I cast a copper jacket upon the shot.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I would the same is to be performed, I
would remark that I do not claim the use of any particular mixtures or alloys
of iron and copper, or other alloys of iron, for the manufacture of projectiles;
but I claim the chill-casting of such mixtures or alloys for projectiles, and
also the chill-casting of cast iron, steel, or wrought iron and cast iron, for use
as projectiles for ordnance, substantially as herein set forth.
In witness whereof, I, the said William Palliser, have hereunto set my
hand and seal, this Twenty-fifth day of November, One thousand eight
hundred and sixty-three.
