Abstract

239,773. Corrie, D. Feb. 7, 1925. Blasting-detonators. - A blasting-detonator comprises a primer tube a containing a fulminate priming charge d in an open-ended base chamber c surrounded by thickened walls b, in combination with a detachable detonator tube f containing a less-sensitive detonating charger g. The tube f is screwed to the tube a or secured to it by a bayonet-joint i, or otherwise detachably connected thereto, the tubes when separated being safe to handle. The primer is ignited by means of a pellet e of black powder fired by an electric or other fuze.
