I, CHARLES AUBREY DAY, of 321, High Holborn, in the County of Middlesex,
Fellow of the Institute of Patent Agents, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF CARTRIDGES (a com-
munication to me from abroad by Louis Georges Bachmann, of 15, Rue Royale,
Brussels, Engineer) to be as follows:-
This Invention relates to certain improvements in or applicable to the manufacture
of cartridges.
In cartridges in present use the firing of the charge of powder is effected at or
adjacent to the bottom by means of a capsule lodged in the rear end. Many
attempts have been made to construct cartridges in which the fire was communi-
cated to the powder at the top or front but none of the processes known to the
present day have been practically successful, and all have been successively and
definitely abandoned.
The object of the present improvements is to render practical the manufacture
of cartridges in which the firing of the powder can be effected not only at an upper
part but can also be effected at any height, or simultaneously at different heights
or parts of the cartridge.
To this end the Invention consists in the use in combination in the manufacture
of cartridges, of a rear socket for receiving the capsule, and of a perforated tube
for communicating fire therefrom, and which are preferably used and combined in
the manner hereinafter described.
The said socket and tube are preferably made in distinct pieces, and the former
is made of a circular form and is provided with a lower outer flange, and with an
upper flange turned inwards and formed with a circular opening for the reception
of the said tube. The tube may be made of any convenient or desired length and
is closed at one end and is formed at its other end (that adjacent to the socket)
with an outer flange which is supported against and within the inner flange of the
said socket.

page_text: The tube is bored or otherwise formed with a series of small holes or through
openings of any desired number size or disposition depending principally upon the
nature of the powder employed and the effect desired to be produced.. These holes
or openings may be made circular, elliptical, square, or as slits or of any other
suitable shape, and they may be disposed at the end or in the sides at any desired
height or heights in such a manner as to cause the powder in which the tube
is embedded to be fired in the manner most convenient for the purpose to be
effected.
The perforated tube may be covered with any suitable slight material in order
to prevent the powder from penetrating within the tube, but the said holes should
be made of such a size as not to permit of the powder passing through.
This improved system of manufacture can be applied to all kinds of cartridges
of whatever size or material they may be composed.

I, CHARLES AUBREY DAY, of 321, High Holborn, in the County of Middlesex,
Fellow of the Institute of Patent Agents, do hereby declare the nature of the
Invention for IMPROVEMENTS IN THE MANUFACTURE OF CARTRIDGES," (a com-
munication to me from abroad by Louis Georges Bachmann, of 15, Rue Royale,
Brussels, Engineer,) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This Invention relates to certain improvements in or applicable to the manu-
facture of cartridges.
In cartridges in present use the firing of the charge of powder is effected at or
adjacent to the bottom by means of a capsule lodged in the rear end. Many
attempts have been made to construct cartridges in which the fire was communi-
cated to the powder at the top or front but none of the processes known to the
present day have been practically successful, and all have been successively and
definitely abandoned.
The object of the present improvements is to render practical the manufacture
of cartridges in which the firing of the powder can be effected not only at an upper
part but can also be effected at any height or simultaneously at different heights
or parts of the cartridge.
To this end the Invention consists in the use in combination in the manufacture
of cartridges, of a rear socket, 1, for receiving the capsule, and of a perforated
tube, 2, for communicating fire therefrom, and which are preferably used and
combined in the manner hereinafter described.
On the accompanying drawings, Fig. 1, represents a longitudinal section of the
parts, and Fig. 2, an external view thereof..
The socket, 1, and tube, 2 are preferably made in distinct pieces, and the former
is made of a circular form and is provided at its opposite ends with flanges, 3, 4,
the former of which is turned outwards, and the latter of which is turned inwards
and is formed with a circular opening for the reception of the tube, 2.. The
tube, 2, may be made of any convenient or desired length, and is closed at one
end, 5, and is formed at its other end (that adjacent to the socket) with at outer
flange, 6, which is supported against and within the inner Hange, 4, of the socket.
The tube is bored or otherwise formed with a series of small holes or through
openings, 7, of any desired number size or disposition depending principally upon
the nature of the powder employed and the effect desired to be produced. These
holes or openings, 7, may be made circular, elliptical, square, or as slits or of any
other suitable shape, and they may be disposed at the end or in the sides at any
desired height or heights in such a manner as to cause the powder in which the tube
is embedded to be fired in the manner most convenient for the purpose to be
effected.
The perforated tube may be covered with any suitable material of light texture
in order to prevent the powder of the cartridge from penetrating within the tube,
but the said holes should be made of such a size as not to permit of the powder
passing through,

page_text: This improved system of manufacture can be applied to all kinds of cartridges
of whatever size or material they may be made or composed.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1. The hereinbefore described improvements in the manufacture of cartridges
for permitting of the firing of the powder thereof being effected at any required
part or simultaneously at different parts, the same consisting in the manufacture
and use of a tube formed in its end of sides with one or more holes or through
openings of any suitable shape and disposition and also formed with a flange for
supporting itself within a circular opening at the bottom or end of a flanged socket
intended to contain the capsule.
2. The combination therewith of any suitable material of light texture
enveloping the perforated tube for preventing the grains of powder from entering
the tube through the said holes therein.
