Abstract
Arming device for sea mines comprising an electric detonator, a transfer charge and an interruptor which can be inserted between the detonator and the transfer charge for separating the detonator and the transfer charge; the detonator is arranged as part of a separate unit which can be inserted into a space in a housing arranged in the arming device; cooperating electric contacts are arranged on the unit and in the space, respectively, for the electric connection of the detonator at the insertion thereof into the space.
Claims17
An arming device for sea mines, comprising an electric detonator;
- a transfer charge;
- and an interruptor which can be inserted between the detonator and the transfer charge, for separating the detonator and the transfer charge;
- the detonator being arranged as part of a separate unit shaped to be inserted in a space in a housing arranged in the arming device;
- the separate unit having a telescopic element, with a spring engaged with the telescopic element for pressing the detonator towards the interruptor;
- and cooperating electric contacts arranged on the unit and in the space, respectively, for the electric connection of the detonator upon insertion in the space.
An arming device for sea mines comprising an electric detonator;
- a transfer charge;
- and an interruptor shaped to be inserted between the detonator and the transfer charge for separating the detonator and the transfer charge;
- the detonator being arranged as part of a separate unit shaped to be inserted in a space in a housing arranged in the arming device;
- cooperating electric contacts being arranged on the unit and in the space, respectively, for electric connection of the detonator upon insertion thereof into the space;
- and latching means for latching the interruptor in the position thereof in which it is inserted between the detonator and the transfer charge.
An arming device for sea mines comprising an electric detonator, a transfer charge, and an interruptor shaped to be inserted between the detonator and the transfer charge for separating the detonator and the transfer charge;
- the detonator being arranged as part of a separate unit shaped to be inserted in a space in a housing arranged in the arming device;
- cooperating electric contacts arranged on the unit and in the space, respectively, for the electric connection of the detonator upon insertion thereof into the space;
- and a hydrostatically actuated means operatively connected over a one way clutch with the interruptor, and displaceable against spring bias under the reaction of hydrostatic pressure, and by a pressure equalizing means actuated by such displacement, for initiating the return of the hydrostatically actuated means under spring bias;
- the one way clutch being arranged to transmit the return movement to the interruptor, for the displacement thereof to the position between the detonator and the transfer charge.
A sea mine combination that is not ready for combat but can be made so by combining parts associated therewith;
- the parts comprising:
- (1) a sea mine;
- (2) a detonator-less arming device;
- and
- (3) a detonator readily and easily combined with the arming device at the time the sea mine is to be made ready for combat;
- (a) the detonator-less arming device being mounted in a space in the sea mine;
- (b) a cover exteriorly of the mine and closing said space;
- (c) the arming device comprising:
- (i) a transfer charge;
- (ii) an interruptor having a safety position;
- (iii) an elongated tubular housing having open ends and extending through the cover, so that one end is open to the exterior of the mine, the other end of the housing facing the transfer charge, but separated therefrom by the interruptor in the safety position thereof;
- (iv) a removable cap closing the open end of the housing;
- and
- (v) stationary electric contacts in the housing forming part of an ignition circuit;
- and
- (vi) an electric detonator unit separately disposed from the arming device and adapted to be readily and easily mounted in the housing of the arming device through said opening when the mine is to be prepared for combat, said detonator unit comprising an elongated element, a detonator charge at one end of said element located at said other end of the housing when the detonator unit is mounted therein, and electric contacts for cooperation with said electric contacts in the housing when the detonator unit is mounted therein.
