In 1867, Nobel received U.S. patent number 78,317 for his dynamite. To be able to detonate the dynamite rods, Nobel also improved his detonator (blasting cap) so that it could be ignited by lighting a fuse. In 1875, Nobel invented blasting gelatine in Paris and patented it in 1876. In 1887, he was granted a French patent for blasting powder "ballistite".
