Title: Improvements in or relating to marine mines or bombs
IPC: F42B22/02
Filed: 1939-11-02
Abstract: 548,758. Marine mines. LOW, A. M. Nov. 2, 1939, No. 29226. [Class 9 (ii)] A marine mine or bomb adapted to be dropped from aircraft comprises an impact device normally disposed in an inward inoperative position, means rendered operative by the action of impact on water to project the impact device to an outwardly operative position, means whereby movement of the impact device effects the firing of the mine and a delay action device so that its detonation may be delayed for a controlled time after setting. The body of the mine is provided with fins 16, an explosive mixture 15, and a detonator 14. A tubular passage 1 passes through the centre of the mine its upper end being substantially sealed by a diaphragm 13 and its lower end by a piston 3 provided with an adjustable valve 18, and supporting in a freely moving manner, by a ball and socket joint, a central rod 2 restrained in central position by a spring 12. This rod has attached to it an insulated contact 8 and at its upper end a spring impact device 6 normally retained in a recess in the mine body and held by a safety pin 6a. Before the mine is discharged the pin 6a is withdrawn on impact of the mine with the water, the piston 3 and rod 2 are thrust upward, the spring impact member is ejected, and the piston is retained in lifted position by a spring catch 3a. The rod is now free to oscillate under impact of a body, such as a ship, with the impact member, but the contact thereon is prevented from making contact with a surrounding ring 9 by limiting stops 17, until sufficient water has entered the central chamber through the valve in the piston to raise a float 10 surrounding the rod and guided thereby so as to bring a contact ring 11 carried by the float into position between the contact 8 and 9; the mine is then armed. The spring impact member may be replaced by resilient arms or by pivoted spring arms secured to the end of the rod 2. The mine may be provided with a float to cause it to float at any required depth of submergence. Instead of firing the detonator by electricity controlled through the contacts 8, 9, the rod may itself actuate a firing pin, or release a spring actuated firing pin, or actuate combined electromagnet and mechanical firing means. The arming device may comprise a clockwork train which may be released by movement of the pin 2 causing actuation of an electromagnet to withdraw a stop.
