Abstract

1,137,212. Igniters for depth charges. THULINVERKEN A.B. 16 June, 1967, No. 27860/67. Heading F3A. An igniter for a depth charge comprises a housing 1 containing a booster charge 17 and a detonator 18, a spindle 8 carrying a striker pin 14 which is secured against displacement by a shear pin 10 until the striker is exposed to an elevated pressure in a surrounding liquid medium, and a piston 11 which bears against the striker pin through a spring 16 and increasingly loads the striker pin towards the detonator with the increasing pressure of the liquid medium which enters the casing through holes 7. Additional safety means are provided by a screw 9 which is unscrewed from the spindle 8 before a depth charge containing the igniter is dropped from a boat or an aircraft, and a Bourdon tube 20 which moves a pivoted safety plate 22 from the line of the striker pin at a surrounding liquid pressure less than that necessary to shear the pin 10.
