IMPROVEMENTS IN PROJEGEILES AND CARTRIDGES
Year: 1852

page_text: LETTERS PATENT to John Macintosh, of Berners Street, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN
PROJEGEILES AND CARTRIDGES."
Sealed the 9th March 1858, and dated the 3rd November 1852.
PROVISIONAL SPECIFICATION left by the said John Macintosh at
the Office of the Commissioners of Patents, with his Petition,
on the 3rd November 1852.
I, JOHN MACINTOSH, of Berners Street, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN PROJECTILES AND CARTRIDGES" to be as follows:-
This Invention consists of making the end covering of a projectile
(having or not its charge of powder within it) with prepared paper or
fabric projecting beyond the back end of the projectile, containing part
or all of the charge of powder therein, so that when a cap or other form
of detonating prime is discharged, it shall ignite the charge through the
prepared paper or fabric without the necessity of puncturing or removing
such fabric. And in order to give rotatory motion to a projectile it is
made hollow and cylindrical, with an inclined projection within, so that
by the passage of air through the projectile rotatory action will take
place.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN MACINTOSH, of Berners Street, in the County of Middlesex,
send greeting.
WHEREAS 1ler most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the 3rd day of November, in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of er reign, did, for Ierself, Ifer heirs and successors, give and
grant unto me, the said John Macintosh, Her special license that I,
the said John Macintosh, my executors, administrators, and assigns, or
such others as I, the said John Macintosh, 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
AND CARTRIDGES," upon the condition, amongst others, that T, the said
John Macintosh, by an instrument in writing under my hand and
scal, 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 Macintosh, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say:
This Invention consists of making the end covering of a projectile
(having or not its charge of powder within it) with prepared paper or
fabric projecting beyond the back end of the projectile, containing part
or all of the charge of powder therein, so that when a cap or other form

page_text: of detonating prine is discharged it shall ignite the charge through the
prepared paper or other fabric without the necessity of puncturing or
removing such fabric. And in order to give rotatory motion to a pro-
jectile it is made hollow and cylindrical, with an inclined projection
within, so that by the passage of air through the projectile rotatory
action will take place. And in order that my Invention may be more
fully understood I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
.
Figure 1, shows the section of a hollow projectile, having within it a
cartridge containing the charge of power. a, is the hollow projectile of
the form I prefer; and b, is the cartridge, for the most part within the
projectile but the form of these parts may be varied, and more or less
of the charge of powder to be placed in the interior. c, is the pre-
pared paper or fabric which is applied at the end of the cartridge and
projectile to close in the powder; and the peculiarity is, that this
part c, is thoroughly impregnated with meal powder, which will ignite
immediately on the discharge of a detonating priming.
Figure 2, shows the section of a new form of projectile, it being
hollow and cylindrical, and is made with a view to pass through the air
with as little resistance as may be, and yet be very effectual when it
strikes an object. And in order to give rotatory motion thereto, I
make it with an inclined or screw formed projection or projections a,
within, so that as the air rushes through the interior the projectile
will rotate; and I prefer, in making hollow shot or projectiles, that such
should be the case, but they may be made plain, or plain on the inside
and projections on tho exterior, to suit a rifle barrel. b, is a plug, which
fits loosely, and drops out when the hollow projectile is passing through
the air.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is,―
First, the mode of making projectiles and cartridges described with

page_text: Secondly, I claim the manufacture of projectiles described by reference
to Figure 2.
In witness whereof, I, the said John Macintosh, have hereunto
set my hand and seal, this Third day of May, in the year of
our Lord One thousand eight hundred and fifty-three.
Witness,
J. G. TONGUE.
