EXPLOSIVE.
No Drawing.
, certain new and useful Explosive, of which the following is a specification.
Our invention relates to explosives.
Our object is the provision of an explosive possessing great strength, which will produce but little flame and noxious gases so that the explosive is particularly safe for use in gaseous and dusty mines.
The object of our invention is carried out by our discovery that a mixture of ammonium nitrate, black oxid of manganese, blue powder or zinc dust with or without the addition of another oxidizable substance,.
such as charcoal, starch, or the like will produce an explosive having the foregoing characteristics.
The foregoing ingredients may be mixed in any well known or preferred manner and their proportions may be varied according to the strength or sensitiveness desired in the resulting explosive, but the preferable limits of percentages of the various ingredients are as follows:
Ammonium nitrate 50% to 80% Black oxid of manganese 7% to 35% Blue powder or zinc dust 8% to 15% The zine dust may be either pure metallic zinc or the so-called blue powder which is a by-product from zinc smelters and consists primarily of metallic zine with a small proportion of zinc oxid in the form of an impalpable powder requiring no grinding before being used in on; explosive. Its cost is so low that it can be profitably used in commercial explosives. The zinc fulfils the usual function of an oxidizable metal of high specific conductivity. v
The zinc oxid has the-property of being antacid, thus causing our explosive to comply with the requirements of the rules of the Interstate Commerce Commission and of the Bureau of Safe Transportation of the American Railway Association.
Nitro compounds ,of organic hydrocarbons of e ithelralcoholie, aromatic, phenol,'or other groups imay be used 'in conjuncton with the above ingredients, in such proportionsas may be desired according to the explosive Specification of Letters Patent.
which is to be made in order to increase the sensitiveness to detonation and also to reduce the tendency of the said mixture to absorb moisture from the air.
In the explosive, the manganese dioxid acts both as an oxidizing agent and as an aid to the propagation of explosive reaction throughout the entire mass.
The explosive has been found in practice to possess high explosive power with the production of a very small quantity of flame and noxious gases, conducing to its use in gaseous and dusty mines.
The following are examples of our explosive:
Ewample N0. 1.
Starch 2% to 10% Example N0. 2. 0 I
Ammonium nitrate 50% to 80% Black oxid of manganese 7% to 20% Blue powder or zinc dllSl3 Pulverized charcoal 1% to 10% 8 Example No. 3.
A. Of the alcoholic group K Ammonium nitrate; 50% to 80% Black oxid of manganese 7% to 20% Blue powder or zinc dust" 8% to25% Nitro glycerin (tri nitroglycerol 2% to 10% B. Of the aromat group: Ammonium nitrate 50% to 80% Black oxid of manganese 7% to 20% Blue powder or zinc dust 8% to 25% Mono-nitro naphthalene 2% t010%- C Of the plonol group: Ammonium nitrate 50% to 80% Black oxid of manganese 7% to 20% Blue powder or zinc dusts" 8% to 25% Picric acid 2% to 10% Example N0. 1,.
A. With the addition of nitroglycerin: Nitrate of ammonia 50 to 80 Black oxid of manganese" 7 to 20 Patented Dec. 14L, 1909. Application filed April 17, 1909. Serial No. 490,000. I
Finely divided zinc B; Without the addition of a nitro compound: Nitrate of ammonia, 50 %to 80 Black oxid or'manganese 7 %to 20 7.2% to 23.5% Oxid of zinc trate, another solid inorganie oxidizing I agent, and comminuted zinc.
Having thus described our inventidn, What We claim as new and desire to seeure by Let 2. An explosive comprising ammonium nitrate, manganese dioxid, and comminnted 15 zinc.
3. A n explosive comprising ammonium nitrate, dioxid of manganese, comminuted zinc, and a nitrated compound. y
In testimony whereof we hereunto affix 20 our signatures in presence 'oftwo Witnesses.
