Office of the Commissioners of Patents, with his Petition, on the
3rd March 1857.
I, EDWARD LINDNER, of New York, United States, Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CARTRIDGES.
AND BULLETS, TOGETHER WITH AN APPARATUS FOR PRODUCING THE SAME," to be
as follows:-
One improvement in cartridges consists in combining, either by casting or
by pressure, the paper or other material for carrying or holding powder with
or on to the bullet or ball.
Another of my improvements in cartridges consists in casting on to the
bullet, as well as the paper or other powder-holding material, a rod or pin,
which projects beyond or even with the back of the cartridge, and carries
either a percussion cap or a chamber containing some explosive composition,
which on being struck by a needle or other like agent fires the cartridge; or
the additional rod may be used simply to impart stiffness to the cartridge.
And my improvement in bullets consists in forming them with rings of
leather or other like suitable material, which will have the effect of cleaning
the barrel from which they are discharged.
My apparatus consists of a moukl fitted with a plunger, round which plunger..

page_text: the roll of paper or other material to carry the powder is placed. This plunger
descends in the mould to such extent that it exposes one of the ends of the
roll to the lead to be subsequently poured in from the end of the mould
opposite that at which the plunger is introduced, and which lead when intro-
duced becomes fixed to the paper or other material.
When bullets are to be fitted with rings of leather or other material, grooves
are made in the mould, and the rings are inserted therein previous to the
pouring in of the lead.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Lindner in the Great Seal Patent Office on the
3rd September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LINDNER, of New York, United States, Engineer, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of March, in the year of our Lord Onc
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward Lindner, Her special licence that I, the said Edward Lindner, my
.executors, administrators, and assigns, or such others as I, the said Edward
Lindner, 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 CARTRIDGES AND
BULLETS, TOGETHER WITH AN APPARATUS FOR PRODUCING THE SAME," upon the con-
dition (amongst others) that I, the said Edward Lindner, 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 Edward Lindner, 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say:
One of my improvements in cartridges consists in combining, either by

page_text: casting or by pressure, the paper or other material for carrying or holding
powder with or on to the bullet or ball.
Another of my improvements in cartridges consists in casting on to tho
bullet, as well as the paper or other powder-holding material, a rod or pin,
which projects beyond or even with the back of the cartridge, and carries
either a percussion cap or a chamber containing some explosive composition,
which on being struck by a needle or other like agent fires the cartridge; or
the additional rod may be used simply to impart stiffness to the cartridge.
And my improvements in bullets consists in forming them with rings of
leather or other like suitable material, which will have the effect of cleaning
the barrel from which they are discharged.
My apparatus consists of a mould fitted with a plunger, round which plunger*
the roll of paper or other material to carry the powder is placed. This plunger
descends in the mould to such extent that it exposes one of the ends of the
roll to the lead to be subsequently poured in from the end of the mould
opposite to that at which the plunger is introduced, and which lead when intro-
duced becomes fixed to the paper or other material. When bullets are to bd
fitted with rings of leather or other material, grooves are made in the mould,"
and rings are inserted therein previous to the pouring in of the lead.
Figure 1 of the annexed Drawings is a view of one half of my bullet mould,
the other half being a counterpart of the same. a, a, are the sides of the
mould; bis the hole or gate for the admission of the lead; c is the plunger,
mandril, or core bar, which terminates conically, as shown at d, and around the
cylindrical part of which the roll of paper for containing the powder is placed.
This paper is formed cylindrically, and made of such a size and length as to
fit the plunger c, and to project a short distance beyond that part of the plunger
where the cone commences; it is there turned over, as shewn at e, and thus
forms a space between the end of the plunger and the paper, so that when
the plunger is inserted in the mould and the lead poured in, it runs round the
paper, which thus becomes embedded in the lead; a concavity in the extremity
of the shot is also formed by the lead running over the conical end d of the
plunger c. f is a ring or washer of leather, or other suitable material, whichi
is placed in a groove of the mould a, so that when the lead is poured in it runs
round that portion of the washer which projects into the interior of the mould
and fixes it. On the bullet being removed from the mould the portion of the
washer which entered the groove forms a projecting ring round the bullet,
which cleans the barrel of the gun from which it is discharged. Any desired
number of grooves 9, 9, are formed in the mould. h is a handle attached to
the plunger for working the same; i, i, i, i, are steady pins on one half of the

page_text: mould, which fit into corresponding holes on the other half of the mould,
and keep the two parts of the mould in proper position whilst the casting
is taking place.
Figure 2 is a side view of one of my bullets, and Figure 3 is a cross section
of the same. The same letters refer to similar parts in all the Figures here-
after mentioned. is the body of the grooved conical bullet or shot; \ is the
ring or washer, of leather or other suitable material; m, m, are the grooves.
Figure 4 is a side view of a cartridge constructed according to my Inven-
tion, and Figure 5 is a cross section of the same. n is the portion which
-contains the powder, connected to the bullet in the manner before described,
or a groove or slit is formed in the bullet and the paper pressed therein.
Figures 6 and 7 shew, in section, cartridges made according to my In-
vention and quite waterproof. The exterior of the case for holding powder
is formed of tin, or other metal foil or leaf, lined with paper. After filling
the case with powder, I insert a wad o, made of paper, papier mâché, or
other like suitable substance, turn over thereon and bend inwards the upper
edge of the case, as shewn in the Figures, I then place the case in the
mould or apparatus and cast thereon the bullet, as before explained.
Figure 8 shows a round bullet connected to the paper for containing the
powder. In this case also the paper is placed in the mould and the lead run
round it.
Figure 9 shews a different form of shot with two leather washers; and
Figure 10 is a view, in section, of the same description of shot having
only one leather washer, with the paper for containing the powder, attached in
this case by pressure; and Figure 11 is an end view of the same.
Figures 12 and 13 shew, in elevation and section, views of round bullets with
two washers of leather, gutta percha, or other suitable material. These balls are
cast in a similar manner to those before described, the washers being placed
in the grooves formed in the mould prior to the running in of the lead.
Figures 14 and 15 are views, in section, of another form of cartridge, where
a rod or pin is cast or fixed to the bullet. 9 is the rod, one end of which is
attached to the bullet k; s is a percussion cap, or a cap containing some
fulminating powder or other explosive material, secured to the opposite
extremity of the rod q. In forming some cartridges I merely employ the
rod q as a support to the part which contains the powder, and thus render the
cartridge much more secure and firm than when the rod is not employed.
Figure 16 is a side, and Figure 17 an end view, of a cartridge where the
point t of the shot is cast of a different shape, and the rod or support is
employed to strengthen the cartridge.

page_text: And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the combining by casting or by pressure of paper or other material,
or of paper combined with metal foil or leaf, for holding powder with or on to
bullets, as herein-before described.
Second, the forming of bullets with rings of leather or other like material,
as before described.
Third, the casting of a pin or rod to a bullet, for the purposes and in
manner before described.
And, fourth, the constructing of moulds or apparatuses for casting bullets
and forming cartridges in the manner herein-before described, and represented
in the Drawings annexed.
In witness whereof, I, tho said Edward Lindner, have hereunto set my
hand and seal, this Third day of September, One thousand eight
hundred and fifty-seven.
EDWARD LINDNER. (L.S.)
