VEILIGHEIDSONTSTEKER VOOR EEN ONDERWATERSPRINGLADING.

摘要

A safety fuse for an underwater explosive, including a piston shiftable longitudinally to detonate the explosive, a diaphragm attached to the piston such that pressure on one side of the diaphragm moves the piston to detonate the explosive and ports communicating with one side of the diaphragm and the exterior of the fuse device for transmitting water pressure to that side of the diaphragm, thereby shifting the piston to detonate the explosive; safety devices which must be removed in order to enable water under pressure to contact the one side of the diaphragm; appropriate spring operated means for driving the piston to detonate the explosive; other protective means against inadvertent detonation.
