Description

UNITED STATES PATENT OFFICE.
GUIDO ALFONS HEDBERG, OF ALINGSAS, SWEDEN.
MANUFACTURE OF EXPLOSIVES.
No Drawing.
To all vr/mm. it may on ern:
Be it known that l, Giulio Anions lino- Bmm, a subject of the King oi Sweden, residing at Alingsiis. in the ounty of .\lf! berg and Kingdom of Sweden, have in vented new and useful Improvements in the Manufacture of Ex wlosives. of which the following is a specification.
This invention refers to an improvement in the manufacture of explosives.
In the manufacture of gelatinized explosives it is known to mix in cork-powder or similar substances so that the air contained in the cells of the said aggregates may increase the detonating effect of the explosive. Said substances however are diflicult to procure particularly in places, where the are not to he found as natural. products. it has also appeared that the said aggregates are not adapted to powder shaped explo- Sives now more and more usual, such as nitrate of ammonia or similar, where it is proved fit to bed intimately the explosive pro )er into a protecting covering.
. l his invention is a result of experiments to find some aggregates more suitable than those hitherto known. It has namely appeared, that fine-ground meal of pine-bark as an aggregate. especially in powder shaped or granular explosives, gives the same a particularly increased effect as also a greater ability to endure storing without losing in explosive effect by taking up moisture. This good effect of the meal of pine-bark appears still more evident, if to the meal of the pine-bark is added some per cent. meal Specification of Letters Patent.
Application filed September 9. 1919.
Patented Apr. 6, 1920.
Serial No. 322,715. v
of pine-corms, which per cent. however may vary within rather extensive limits, viz., be tween (MC; and 20%- The g()()(l effect of the meal of fine-hark and the meal of pine-cones on t e explo sives may be ascribed to their percentage of resin or incrusted substances.
'hen manufacturing an explosive in acvordance with this invention the explosive material is thorough]; mixed with the meal of the pine-bark, intermin 'led with meal of cones, so that the grains 0 the granular explosives are caused to he intimately embedded within the bark and cone-meal.
Having thus particularlydescribed and ascertained thenature of my said invention and how the same is to he performed I declare. that what I claim is:
i. In explosives. in combination with the explosive materials proper, meal of pine hark and meal of pine-cones as an intimate mixture.
2. Explosives as claimed in claim 1 the quantity of cone-meal representing 0.5 up to 20 per cent. of the meal of pinehark.
3. An improved method (if/manufacture of explosiv s, characterized. therein, that granular explosives are thoroughly mixed with aggregates of meal of pine-hark and meal of pine-cones, so that the explosive grains are caused to he intimately embedded in the barlmneal and cone-meal.
In testimony Whereoi I have aflixed my signature.
