PROVISIONAL SPECIFICATION.
Improvements in Blasting Cartridges.
We THEODOR PUSKÁS, Director of a Telephone Company and IVÁN
SCHLENKER, Blasting Engineer, both of 10 Museum Ring, Budapest, Empire of
Austria-Hungary, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of a blasting-cartridge, the object of
which is to increase the effect of the blasting-material. The invention consists in
making cartridge-shells of every possible shape, thicker along the surface or side
further from the object to be blasted, whilst the opposite surface or side is made
thin, so that the gases of the exploding blasting-material have more difficulty in
bursting the strong surface further from the object to be destroyed and less
difficulty in bursting the thin surface nearer said object, whereby the whole effect
of the gases produced is directed towards the object to be burst, which is of course
of great advantage.
The invention is performed by making the cartridges conical or cup fashion or
any convenient shape with or of metal or other material of a certain thickness
with a base of metal or other material considerably thinner on which the cartridge
rests or is placed when operated.

We THEODOR PUSKÁS, Director of a Telephone Company and IVÁN
SCHLENKER, Blasting Engineer both of Budapest in the Kingdom of Hungary
do hereby declare the nature of this invention 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 the construction of a blasting cartridge the object of
which is to increase the effect of the blasting material. The invention consists in
making cartridge shells of every possible shape thicker along the surface or side
further from the object to be blasted whilst the opposite surface or side is made thin

the strong surface further from the object to be destroyed and less difficulty in
bursting the thin surface nearer said object whereby the whole effect of the gases
produced is directed towards the object to be burst which is of great advantage.
The accompanying drawing represents in section in Figs. 1 to 4 the construc-
tion of such cartridge shells in various different shapes usually employed.

is the part
near to the object to be burst and consists generally of a thin sheet of iron, brass,
copper or the like and may have also any optional shape. Within the cartridge
shell is the explosive substance c which is operated upon in the same fashion as
with other blasting cartridges by known priming devices inserted into the opening d
of the strong part a of the shell.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
Cartridge shells for blasting having the part a of the cartridge remote from the
object to be blasted constructed of more resistance than the part 6 next to the
object to be blasted for the purpose set forth.
