Description

UNITED STATES PATENT OFFICE.
KNUD VALDEMAR NIELSEN AND J ENS PETER LARSEN, OF AARHUS, DENMARK; SAID NIELSEN ASSIGNOR 1'0 SAID LARSEN.
EXPLOSIVE AND PROCESS OF MANUFACTURING THE SAME.
No Drawing.
To all whom it may concern:
" Be" it known that we, KNUD VALDEMAR NIELSEN and -JENs PETER LARSEN, merchants, subjects of the King of Denmark, residing at Aarhus, Denmark, have invented a certain new and useful Explosive and Process of Manufacturing the Same, of which the following is a full, clear, and exact description.
The present invention relates to an explosive, by means of which great explosive power is obtained, while the explosive is comparatively safe to handle, and its manufacture is simple and so cheap, that it can be utilized to a greater extent than the explosives hitherto used.
The explosive consists of a chemical and mechanical compound of ammonium nitrate, sulfur, potassium nitrate and a fatty substance, for instance glycerin, together with Sago-flour, pyrolusite, and resin, in such a manner, that the whole forms neither a solid nor a pulverulent composition, which is not ignited by shocks, and which, if exposed for a short time to fire, burns without explodg. The following is a suitable mixture: 78. 125 parts of ammonium nitrate (nitras ammonicus) 8.7 50 parts of sulfur (sulfur sublima- 7. 500 parts of potassium nitrate (nitras kalicus) KNO 2. 500 parts of glycerin (glycerinum),
1.250 parts of Sago-flour,
1. 250 parts of pyrolusite (superoxydum manganicum) MnO,, 1
0. 635 parts of resin (resina colophonium).
The explosive is made in the following manner: Sulfur, glycerin, pyrolusite and resin are melted together by an even heat to a liquid consistency, to which is afterward added potassium nitrate and sago-flour. The mixture is then allowed to cool off, so that it can be finely powdered in a mortar or a hand-mill. Ammonium nitrate is then added to the powder and thoroughly mixed with" it; thereupon the composition is heated slowly in a closed receptacle until it becomes Specification of Letters Patent.

a thin liquid. It is then poured off and for use and may be ground, for instance to -a moderatelyfine powder, for the ignition of which a percussive action is necessary.
In order to utilize the explosive, it is placed in the form of a cartridge or a loose powder, in or near the object to be exploded, and is ignited by the percussion of a fulminate of mercury percussion cap ignited by a fuse, ordinary priming, or an electric spark.
The chief characteristic of the explosive which is the object of the present invention is its contents of sulfur and potassium nitrate combined with ammonium nitrate and glycerin with an admixture of pyrolusite, resin and Sago-flour, and that it cannot be exploded by the heat generated by a lighted match applied to it, nor by shocks. It is, therefore, exceedingly easy to handle and, when caused to explode by means of a percussion, its explosive power is about twice that of dynamite.
Having now fully described our inven- Letters Patent is:
1. The process of making an explosive in which sulfur, glycerin, pyrolusite and resin are melted together, to which are then added potassium nitrate and Sago-flour, whereupon ammonium nitrate is added to the powder.
2. An explosive consisting of 7 8.125 parts of ammonium nitrate, 8.750 parts of sulfur, 7.500 parts of potassium nitrate, 2.500 parts of glycerin, parts of pyrolusite, 0.635 parts of resin.
3. An explosive containing sulfur, potassium and ammonium nitrates, glycerin, a starchy substance, resin and pyrolusite.
4. An explosive containing sulfur potassium and ammonium nitrates, glycerin, sago-flour, resin and pyrolusite. I
In testimony whereof we aifix our signatures in presence of two witnesses.
