' Explosives, of which Application filed Septpmber 9, 1908. Serial No. 452,286.
To'aZZ whom it may concern: I
Be it known that I,'WALTER HARCOURT PALMER, asubject of the King of Great Britain and Ireland, and residingat Porsgrund, Norway, have invented certain new and useful Impro vements in and Relating to the following is a specification.
My invention relates to explosives for blasting purposes and has for its object the production of an ex losive which shall not be liable to explo e prematurely under shocks or the action of heat or cold and which-is not liable to freeze so that. the danger which occurs in thawing frozen explosives such as nitroglycerin explosives is avoided.
The invention consists in a blasting explosive -containing perchlorate of ammonia,
dinitrotoluol and nitrate of soda which are bound together with paraflin wax or other suitable moderating, binding and water proofing material.
The invention further consists in the improved explosivehereinafter described.
In carrying my invention into eflect according to one example I make a mixture effect of the specific containing 50 per cent. of perchlorate of ammonia, Lifer cent of dinitrotolnol and 31 per cent. 0 nitrate of soda or its equivalent and incorporate therewith 1;) per cent.
- paraflin or other hard w'ax, that will not melt under 120 Fahrenheit which will have the effect ofholding the constituent parts in position, keepingthe composition of the mixture constant and also serving to protect the explosive from decompositlon by the effects of air and moisture, thereby making the explosive perfectly constant. The wax is used for the purpose of keeping the particles properly mixed and nullifying the gravity of the com ponent parts. The method of mixing theingredients is as follows :'.-The perchlorate. of .ammonia and nitrate of soda are thoroughly ground together until they are in an extremely fine powder. I The paraffin wax-and dinitrotoluol having been meltedtogether are slowly run on to the mixed perchlorate and nitrate and The proportions of the various ingredients above given may be varied according to the application for which the explosive is required, and their ratio may be varied according as to whether a quick or slow explosive is required. Thus, where an ex-' ceptionally quick explosive is needed the following proportion of the various ingredients are suitable. per cent. perchlorate of ammonia, 13 per cent. dinitrotoluol, and a nitrate of an alkali metal that is to say, 10 per cent. nitrate of soda, or its equivalent of nitrate of potash, 7 per cent. paraflin wax.
I find that my improved composition is cheap to manufacture and produces an explosive of great power which will not leave noxious fumes and is therefore especially suitable for use in mines and other closed places. Also the explosive is safe from premature explosion by shocks or heat. The new composition also is non-hygroscopic and may be used in wet or dry work and does not freeze even at below zero.
Having thus described my invention what I claim as new and daire to secure by Letters Patent is An explosive composition containing the following ingredients in substantially the proportions given:
Perchlorate of ammonia per cent. Dinitrotoluol 14: per cent. Nitrate of soda 31 per cent.
Parafiin wax of melting point above F I In testimony whereof I have signed my name to this specification .in the presence of two subscribing witnesses.
