Definitions
- ALFRED NOBEL of the city of l-lamburg', Germany, has invented certain new and useful Improvements in the Manufacture of Nitro-Glyeerine and certain compounds thereof, and in the utilization, as explosives, ot' nitroglycerine and the analogous substances known as nitrates of ethyl and of methyl and nitromanite.
- nitro-glycerine is the subject of a separate specification; this specification having reference to certain modes of utilizing, as explosives, nitro-glycerine and the analogous substances above mentioned.
- Nitro-glycerine for example, if ignited in an open space, is slowly decomposed and takes fire, but the flame is apt to die out when the match is withdrawn; hence it cannot under ordinary circumstances be looked upon as a ready explosive agent, for while gunpowder and other substances used as explosives prior to NoBELs invention, always explode or deflagrate throughout their whole mass when fire is set to them, nitroglycerine and the analogous substances before named will not explode from the mere contact of flame. So, also, if a drop of nitro-glycerine be poured on an anvil, the blow of a hammer causes it to explode, but only that part is involved which has received the blow, so that in this case the explosion is merely a local one.
- a principal object of NOBELS invention consists in the removal of this obstacle to the ,use of nitro-glycerine and the analogous substances before named, as explo si'ves.
- two diii'ercntfmethods' have beeninv ehfted byNonnL for promoting the explosion of nitro I glycerine.
- One method, which formsthe sub ject of this patent, relates to a compound with nitro-glycerine of other more easily explosive substances; and the other method, which is described in a separate specification, relates to the means of efl'ecting the explosion.
- NOBEL discovered that the'diificulty experienced in eflect-ing the explosion of nitro-glycerine, and the analogous substances before mentioned, could be overcome by mixing or combining them with gunpowder, gun-cotton,
- This mixing may i be cfl'ected in any convenient manuer andthe' proportions in which they are to be combined may be varied to suit the pleasure or convenience of the user or manufacturer.
- nitr glycerine say thirt-yper cent, more or lessm such proportions as to make the compound either wet or comparatively dry.
- gunpowder it may be either absorbed with it by pour ing the nitro-g-lycerine on the mass of gunpowder, or the two may be mingled togeth or by tiituration, the powder in the nitro-glycerine.
- the eii'eet ofthesc combinations will produce an explosive especiallysuitablefor certain blasting purposesfor example, in crevice rockand greatly superior either to gunpowder or, gun-cotton in explosiveforce, and quite readily exploded, so that it may be fired and exploded by means of match or electric spark in like manner as -gunpowder or gun-cotton alone.
- nitro-glycerine may be mixed with gunpow- ALFRED NOBEL, and desire to secure by Letters Patent, in the na me of the United States Blasting-Oil Company, ⁇ is assignee of said NOBEL:
