Year: 1877

page_text: LETTERS PATENT to Abraham Greaves, of Chesterfield, William Samuel Greaves,
of Ironville, and Abraham Walter Greaves, of Chesterfield, all in the County
of Derby, for the Invention of "IMPROVEMENTS IN BLASTING CARTRIDGES.”
PROVISIONAL SPECIFICATION left by the said Abraham Greaves, William
Samuel Greaves, and Abraham Walter Greaves at the Office of the Commis-
sioners of Patents on the 15th June 1877.
ABRAHAM GREAVES, of Chesterfield, WILLIAM SAMUEL GREAVES, of Ironville,
and ABRAHAM WALTER GREAVES, of Chesterfield, all in the County of Derby.
"IMPROVEMENTS IN BLASTING CARTRIDGES."
The improvements have for their object the affording greater security, ease, and
facility than heretofore in manipulating, transporting, and storing cartridges, and
consist in making cartridges filled, or to be filled with gunpowder or other equivalent
explosive matter, in the ordinary manufactured state or in any state of manufacture,
hollow, with an inner tube or tubes passing through them, and by means of such
hollow space or spaces passing one or more fuses through such cartridges; and also,
when it is required to increase the charge afforded by one such loaded cartridge,
stringing two or more of such cartridges together on the said fuse or fuses. Also in
turning up, looping, or otherwise treating the fuse so introduced for the purpose of
securing and firing the cartridge or cartridges strung thereon.
The cartridge may be made of any convenient material, tubular or other shape, with
an inner and outer tube or chamber, forming between them a hollow receptacle for the
reception of the gunpowder or other explosive equivalent; and the ends of such
chamber or hollow receptacle may be formed of, or secured by annular discs or other
shaped pieces, so secured to the walls of the hollow receptacles, that when completed
and charged the explosive material shall not fall out, but the fuse pass easily, and so
a hollow cartridge be formed ready for stringing on a fuse or fuses.

"IMPROVEMENTS IN BLASTING CARTRIDGES."
The improvements have for their object the affording greater security, ease, and
facility than heretofore in manipulating, transporting, and storing cartridges, and
consist in making cartridges filled or to be filled with gunpowder or other equivalent
explosive matter, in the ordinary manufactured state or in any state of manufacture,
hollow, with an inner tube or tubes passing through them, and by means of such
tubular or hollow space or spaces, passing one or more fuses through such cartridges;
and also, when it is required to increase the charge afforded by one such loaded
cartridge, stringing two or more of such cartridges together on the said fuse or fuses.
Also in turning up, looping, or otherwise treating the fuse or fuses so introduced for
the purpose of securing and firing the cartridge or cartridges strung thereon.
The cartridge is to be made of any convenient material,. tubular or any desired
shape in section, and of an inner and outer tube or chamber arranged concentrically
one within the other, or otherwise, and forming between them a hollow receptacle
for the reception of the gunpowder or any other explosive equivalent; and the ends
of such chamber or hollow receptacle are to be formed of or secured by annular
discs or other shaped pieces so secured to the walls of the hollów receptacles; that
when completed and charged the explosive material shall not fall out; or other con-
venient modes of securing the ends may be employed, but in all cases so arranged
that the fuse or fuses pass easily, and so a hollow cartridge be formed ready for
stringing on a fuse or fuses.
In witness whereof, we, the said Abraham Greaves, William Samuel Greaves,
and Abraham Walter Greaves, have hereunto set our hands and seals, this
22nd day of November, in the year of our Lord One thousand eight hundred
