IMPRQVEMENT 1N EXPLOSIVE COMPOUNDS.

Specification forming part of Letters Patent No. 138,841, dated May 13, 1873'; application filed April 11, 1873.

Be it known that I, TREAT s. BEACH of the city of New York, county and State of New York, have invented a new composition of matter, beingan explosive compound, useful for blasting rocks and other similar purposes, of which the following is a specification: My invention consists in a composition of matter made by combining one or-more of each of the following, four classes of substances, Viz': First,v an alkaline nitrate or,

some salt which will produce substantially the same result; second, nitro-glycerine or some of the equivalent nitro-substitution prodtrate of potash, nitro-glycerine, wood-fiber, and

paraffine, which should be employed in about the following proportions: nitrate of potash, forty parts; nitro-glycerine, forty parts; woodfiber, thirteen parts; parafline, or its equivalent, seven parts. Thesolid ingredients should be separately reduced to a fine powder in any suitable way, and thoroughly mixed. Then the nitro-glycerine is to be added and all thoroughly'ineorporated together. 7 It is best to prepare the wood-fiber'(prefe1-ably poplar) by first reducing itftoa pulp, and, then neutralizing its natural acids by boiling it in an alkaline solution; for example, put, say, twen-' ty poundsof the pulp into fifteen gallons of water, in which fourvounces of bicarbonate of soda are dissolved, and boil it for three hours, E

gree the explosive character of the cdmpound, Y

but in some degree improves it.

In'pla-ce of the paraifine hardpiteh may be used, which in this coinpound would be the equivalent of the paraffine, or both pitch and ,pEtI'flfiillG may beemployed, using, say, two

say, two parts of each, but these are not es vsential. v

What I claim by my invention, and dlesire to secure by Letters Patent, is-

1. The explosive compound, made of tile in gredients herein specified andcompoun ded.

as described;

2. An explosive compound, made with, any

three of the four classes herein specified.
