JOSHUA H. ROBERTSONJOF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO I CHARLES W. RANDALL, OF SAME PLACE.
EXPLOSIVE COMPOUND.
SPECIFICATION forming part of Letters Patent No. 307,989, dated November 11, 1884.
'iipiilieatlon'fil'eilDecember l, lass. Renewed Oet0ber22, 1884. (No specimens.)
To all whom it may concern:
Be it known that I, JOSHUA H. ROBERTSON, of the city and county of San Francisco, State of California, have invented a new, useful. and Improved Explosive Compound; and I hereby declare the following to be a full specification of the same, sufficient to enable a person skilled in the art to which my invention appertainsto make, compound, and use the same. a 1
My invention consists in combining anhydrous sodium su'lphatecommonly known as sulphate of soda -with nitro-glycerine, thus forming a new and improved explosive compound; and among the advantages possessed by my compound are diminished cost of production, increased tenacity of unioubetween the ingredients, and a material diminution of n'ox ions fumes. A proportion of nitro-glycerine which, in a compound consisting of infu'sorial or silicious earth and nitro-glycerine, cannot be exploded, can in my compound be readily and certainly detonated, and, being non-deliquescent, it is not readily affected by moisture.
To produce my compound I place sixty-five pounds of finely-pulverized anhydrous sulphate of soda in a wooden tank or other suitable receptacle, and gradually add thereto thirty-five (35) pounds of nitro-glycerinc. I stir the mixture by a wooden rake or other suitable utensil until the nitro-glycerine and sulphate of soda are thoroughly incorporated together, when the compound is ready to be placed into cartridges for use.
I do not desire to limit myself to the proportions of the ingredients herein stated, but give the foregoing as an example merely, the relative proportions being susceptible of considerable change, in accordance with the desired strength or grade of the explosive.'- The strength of the explosive may be increased or diminished by increasing or diminishing the proportion of nitro-glycerine, the illustration given being taken as a standard, care being taken not to add sufficient nitro-glycerine to reduce the compound to a soft or pasty eonsisteney. When properly prepared, the explosive is of a granular or pulverulent character.
The manner of firing my explosive is the same as that in common use--by means of a detonator, either with or without a primingcharge.
I obtain my anhydrous sulphate of soda at then ground to an impalpablepowder; In this condition the product is ready for use.
I am aware that thisprocess is old, and therefore do not claim it. From whatever source the anhydrous sulphate of soda is obmay contain shall be expelled or neutralized before combining it with the nitro-glycerine.
I am aware that various infusorial, silicious, and volcanic earths have been mixed with nitro-glycerine; also of the United States patent of Shatfner, N 0. 93,7 52, in which anhydrous sulphate of lime has been mixed with nitroglyccrine and allowed to set to form a solid mass; also of the United States patent to Fowler, granted February 12, 1878, in which non hydrated sodium sulphate is described as mixed with other ingredients and with nitro.- glycerine.
In an application filed by mein the United States Patent Office February.,13, 1884, No; 120,631, and allowed October 18, 1884, I have claimed, broadly, a mixture of granular auhydrous salt and nitro-glycerine, and I claim in this application only the specific elements and in substantially the proportions specified.
Having described my invention, .what I claim, and desire to secure by Letters Patent, 1s-
A new and improved explosive compound, consisting of anhydrous sulphate of soda and nitro-glycerine.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 20th day of November, 1882.
