Be it known that I, ERNEST A. LE D'UEUR,

' a citizen'of the Dominion of Canada", residing at Ottawa, in the county of Carleton and p corporate in the ordinary way sufficient Province of Ontar o, Canada, have lnvented chlorate to make the mixture of any service as an explosive would result in a treacherous compound which would be placedon the prohibited list. 7 I

am aware that explosives have been compounded of nitrate of ammonia proof -which-the following 1s a specification.

-My invntion consistsof an explosive which takes advantage of. the fact which I have discovered that if a mixture of suitable such as crude petroleum, petroleum jelly and I the like, and with chlorate of otash worked face of its grains asmall'quantity of'powdered into the mixture; and I am a chlorate of potash, the resultant material becomes completely explosive by detonation drocarbon mixed first with a'quantityof sa t- (t e orlginal'mixture belng entirely insensipeter and. then with a (larger)v amount of chlorateof potash, but I am not aware of an explosive ever having been prepared which anticipates myabove described invention. In the claims, saltpeter isunderstood to mean nitrate of soda or potash. I claimi l 1. An explosive consisting ofgrains of a ower, cost for cost, than any explosive itherto roduced.

The f0 owing will describe themethod of preparation :Melt' about 12% lbs. of paraffin wax and'fadd about 11 lbs. of ground sulfur, and then thoroughly mix i about 54 lbs. of ground nitrate of soda. uring mixing keep the mass well loosened up with rakes or the like. Allow the mixture to cool and stifien .drocarbonaceous material, coated with pow dered chlorate of potash. r 5

explosive consisting'of grains of a mixture containing saltpeter, sulfur and hydrocarbonaceous material, which latter is solid at ordinary temperatures, coated with powdered chlorate of potash.

3. An explosive consisting of grains of a through a wlre screen of convenient sizev mesh, whereby the -mass. is ,comminuted.

hen mixin about 22% lbs. of 'owdered chlorate of potash, which forms-a ight and porous coatmg on the particles of the 'pre-' vious mixture. This makes, as stated, a powerful as well as cheapexplosive, and retains its porosity sufficiently for use inbulk I may even, especially for pouring loosely into rock seams and the like, still fur-- ther diminish the chlorate and yet secure good detonating properties. In such work I ave even secured detonation, and the liberacoated with powderedchlorate of potash.

In testimony whereof I have signed my two subscribing witnesses.
