An Improved Blasting Powder.
We, STEFAN FÖLör, House Steward, of 5, Angyal-utcza, Budapest, and MATHIAS
JULIUS LACKOVIC, Agent, of 2, Kapoluan, Budapest, do hereby declare the nature
of this invention to be as follows:-
The present invention relates to a blasting powder which can be handled with
greater security than that at present in use while the violence of the blasting is
locally confined and the blasted material is not hurled into the air, so that the
operator by walking to a distance of scarcely fifteen paces is in perfect security
from danger.
A further advantage of this blasting powder consists in the simple and altogether
dangerless method of production.
The invention consists in production from pulverized horse-dung, saltpetre,
fine gunpowder and sulphur as hereafter to be described.
In the production of blasting powder in accordance with the present invention
horse-dung is dried then pulverized and sifted through a fine sieve and the coarser
particles separated as useless.
The saltpetre and sulphur are likewise pulverized, finely sifted, and intimately
mixed with the gunpowder. This mixture is finally added to the horse-dung
prepared in the manner before described.
The horse-dung-powder insulates the gunpowder particles from one another
and serves for increasing the expanding force.
The blasting powder is fired in the ordinary way by means of the usual explosion
apparatus, and by fuzes or electric sparks.
In the experiments we have already made we have employed as a suitable
mixing proportion for 100 parts by weight of the blasting powder,
28 parts by weight of pulverized horse-dung,
39 parts by weight of saltpetre,
23 parts by weight of pulverized fine gunpowder,
10 parts by weight of sulphur,
and in this proportion the following quantities are used in-
a bored hole 1 metre deep
a bored hole 2 metres deep
a bored hole 3 metres deep
a bored hole metres deep
a bored hole 5 metres deep
38 decagrams
78 decagrams
128 decagramis
188 decagrams
258 decagrams
In charging the bored holes, bars of iron or steel may be used in ramming
without fear of any premature explosion.

In charging the bored holes bars of iron or steel may be used in ramming

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: :-
1. A blasting powder produced from dried horse dung, saltpetre, gunpowder
and sulphur which are pulverized, finely sifted and intimately mixed as described.
