The essential nature of my discovery consists in using mineral coal as a substitute for charcoal in the composition of gunpowder and blasting-powder.
To enable others skilled in the art to make use of my discovery, I will proceed to describe it.
Take best quality white-ash anthracite coal or coke, entirely free from bituminous matter;
reduce the coal or coke, by grinding or otherwise, to fine dust; put the dust into some con-.
venient drying-place where let it remain for twelve months freely exposed to the air, when it will be fit for use; reduce nitrate of potassa and pure sulphur separately also to line dust;
What 1 claim as my discovery, and desire to secure by Letters Patent, is-
The treatment of mineral coal in the manner described preparatory to using the same as a substitute for charcoal in the manufacture of gunpowder and blasting powder, as herein substantially set forth.
E. B. DODSON.
