PROCESS OF PRODUCING EXPLOSIVEi-POWDER.
Specification of Letters Patent.
' Patented Nov. 27, 1906.
Application filed February 1-1, 1906. Serial No. 301,540.
To all whom it may concern.-
Be it known that we, FRANCIS I. DU Pour, a citizen of the United States, and FIN SPARRE, a subject of the King of Norway, residing at Wilmington, county of Newcastle, and State of Delaware, have invented a new and'useful Improvement in Processes of Making Smokeless Explosives, of which the following is a full, clear, and exact description.
' Our invention relates to certain im rovements in the rocess of making smo elesspqwder explosives forming the invention of tters Patent No. 503,583, dated A t 22, 1893. In that patent nitrocell v ose andwater are stirred up and a liquid not soluble in water, but which is a solvent of the nitrocellulose, is added and the mass kept in agitation thus forming grains, the being sohdified by heat. It has been iiund in practice with this process that there is a tendency for some grams to be formed which are more dense than others, due to the fact that there is less nitrocellulose in proportion to the solvent in these grains than in the others. These more dense ains on shootingdonotburninagunint esamemanner that other grains do, there frequently being a residue left after shooting.
We have discovered that if we partially re-.
place the nitrocellulose solvent by a substance soluble in the nitrocellulose solvent insoluble in water and not a solvent of nitrocellulose and the process of the aforesaigipatent, No. 503,583, be otherwise follow we obtain all the grains of proper density and nearl uniform as re ards their complete burning in the barrel oi a As an example of the proportions of our improved process we take one (1) part of nitrocellulose-in eight (8) parts of water, to which is. added-one (1) part of amyl-acetate and one-quarter (l) part of a diluter. either lose is sus nde and not a solvent of nitro-- cellulose, ut soluble in the nitrocellulose solvent.
In testimony of which invention we have hereunto set our hands, at Wilmington, Dela ware, on this 3d day of February, 1906.
