The invention relates to marine mines with mechanical ignition device, in which a spring tensioned by the train in the anchor rope serves to advance the ignition device to secure the throwing of the mine. For this purpose, the anchor rope engages by means of a Rod on a device which is so under the action of a spring that it is in relaxed states, d. i. so before throwing, the triggering device for the ignition device holds in a secure position, while with a sunk mine under compression the spring as a result of the pull in the anchor rope, the triggering device for the ignition device is unlocked. The essence of the invention is that the through the train in the anchor rope compressed spring after releasing the release device even brings the ignition device to effect.

The invention is shown in the drawing, namely FIG. 1 shows a vertical section through the mine, and FIG. 2 shows a further vertical section normal to the sectional plane of FIG. 1 through the part of the mine representing the ignition device. A denotes the spherical housing of the mine and B denotes a cylindrical container located axially in this housing, in which the detonator and a powerful explosive charge are located. The lower end of the container B is screwed to the housing A and contains an axial, tubular chamber B ¹ in which a device e ² , e ^{2 is} guided by means of a fixed disk b and is connected to the anchor rope c by a rod C. . The device e ² , e ² is attached to a crosspiece E ¹ in which bearings e ^1, which can be easily rotated with pins, are arranged. In the bearings e ¹ are arms e ^x which are provided with weights E at one end and loosely engage with their other end in grooves of a part ^V E ^{X in} such a way that they can be moved out of the grooves ^{by turning the arms e x.} A helical spring C ¹ , for which the disk δ serves as an abutment, is supported from below against the part E ^x. On the part E ^x there is a firing pin e, over which a primer e ^{i is arranged} for igniting the mine, so that when the arms e ^{x are unscrewed} from the grooves in part E ^x this can be snapped up by the spring C ¹ to detonate the mine. In the idle state before the mine is thrown, where the arms e ^{x are} in engagement with the part E ^x , the spring C ¹ through the intermediary of the part E ^x

the crosspiece E ¹ is pressed upwards so that the ball weights E rest in pan-like cavities D of a disk D ¹ and thus turning the arms and releasing the part E ^x with the firing pin is impossible.

If the mine is pulled under water during throwing, the device e ² , along with the crosspiece E ¹ and the ball weights as well as the part E ^x , is pulled downwards under tension of the spring C ¹ by the pull in the anchor rope c , so that the Ball weights E can be removed from the sockets D and so the arms e ^x can be rotated for the purpose of releasing part E *. The buoyancy of the mine is measured in such a way that with a current of four knots it can be considered by more than 30 °.

When a ship hits the mine, the ball weights E are swiveled around on the one hand by flipping the mine and on the other hand by the impact and release the part E ^x with the firing pin, which then causes the ignition.

So that the ignition device cannot be triggered by the pressure wave when a mine ^{explodes in the vicinity, the plate D 1} is firmly connected to a spring plate d. This spring plate is located at the upper end of the cavity provided in the mine housing for the container B and is connected to the outside water at its top through openings d ¹ provided in a cover D ² closing this cavity at the top. The openings d ¹ can be closed in a known manner by inwardly opening flap valves d ^2. The spring plate is loaded by a spring d ³ above it. When a mine explodes in the vicinity, the spring plate d is moved downwards, the pans going down and the spherical weights E held by reaching over them. The flap valves d ² prevent the water from exiting, so that the spring plate d and the pans D cannot move upwards again until the pressure wave has subsided.

Instead of a coil spring, any other spring can be used for the rod C. will.

Claims (1)

Patent claim: A sea mine with a mechanical ignition device, which is ready for action due to its buoyancy, in which a spring tensioned by the pull in the anchor rope serves to secure the ignition device from sinking the mine, characterized in that this spring (C ¹ ) on a firing pin ( β) supporting part (e *), affects the bears against the free ends of arms (e ^x), the β with bearings ⁽¹⁾ in such a way in a connected to the hawser by rods (e ^2, e ²⁾ plates (e ¹ ) are attached so that they can rotate freely in this with pegs and that the plate (E ¹ ) is held in the raised position due to the pressure of the spring (C ¹ ) through the intermediary of the part (E ^x ) before the mine is thrown , whereby ball weights (E) are on the arms (e ^x ) in pans (D) of a plate (D ¹ ) and are secured against movement by them, while after throwing the mine by the pull in the anchor rope the plate (E ¹ ) together with part (E ^x ) and balls (E) is pulled down in such a way, d ate the balls (E) are free and when tilting the mine as a result of hitting a ship, turn the arms (e ^x ) so that they release the part (E ^x ) with the firing pin for the purpose of firing. 1 sheet of drawings.
