American Antitank Or Antipersonnel Mine

This is a small cylindrical mine containing 6 lbs. of high explosives. It employs a spider to transmit pressure to the fuse. The flanged rim on top of the body is matched in two places for assembling the spider.

The fuse used with the mine is the MI. AT. fuse which is inserted into the fuse pocket on the top of the mine. On the side of the mine is a carrying hand le.

Arming.

(a) Remove the spider from the bottom of the body.

(b) Insert the fuse and push down until it engages. When this is assembled, the upper surface of the fuse body is flush with the upper surface of the mine.

(c) Assemble the spider by aligning, but not so as to engage two hooks with notches in the flange of the body. Engage the other two hooks over the flange on the body, press the first two hooks through the notches, then rotate the spider to engage the other two hooks.

(d) Withdraw the safety fork and lay it beside the mine.

Disarming.

(a) Replace the safety fork.

(b) Rotate the spider and lift off.

(c) Remove the fuse and repack it in the container.

(d) Replace the spider.

DUTCH MINE, AI7TI-TANK.

This is a small, cylindrical mine, more dome-shaped than the British mine. The mine lid is not normally removed from the body, but is held in position by four screws, a light spring keeping it raised off the body.

In the body of the mine is a screwed hole to receive the fuse. A corresponding hole on the lid is closed by a screwed plug.

The fuse assembly screws into the body of the mine. For inspection, insure that none of the mine is badly dented, or has the mine cover, knurled plug or the retaining screws missing.

Arming and testing.

(a) Unscrew the knurled plug on top of the mine cover, thus exposing the waxed cork.

(b) Check for the presence of the coil spring under the mine cover by depressing the cover by hand.

(c) Extract the cork pressing down on the mine cover to expose it fully. Care must be taken to prevent any pieces of the broken cork to fall into the detonator cavity, which would prevent the arming of the mine.

(d) Insert a fuse assembly fully into the fuse cavity with the safety-pin in place. Depressing the mine cover, screw the fuse as far as it will go, without force.

The knurled flange should lie closely on top of the mine body itself. If this is not possible, unscrew the fuse and inspect the fuse cavity for obstruction,- TlfT or broken cork. If the cavity is free, and if another fuse cannot be screwed home, reject mine.

(e) With the fuse in position, the knurled plug in the mine cover cannot be reinserted until the safety-pin is withdrawn, on account of the vertical arm of the latter. Therefore, unless the mines are to be armed or laid at once, remove the fuse, repack and replace the knurled plug.

Arming and laying.

(a) Remove the knurled plug.

(b) Examine the fuse, making sure that the copper shear-wire (located under the knurled flange) is in good condition. If so, remove the split-pin and place it with its attached cord in the hole, for further use if the mine is lifted.

(c) Insert and fully screw in the fuse, depressing the mine cover while doing so to enable the fingers to grip the knurled flange.

Arming and laying.

(d) When fully satisfied that the fuse is screwed home, release the mine cover. Then refit the knurled plug. During this operation, do not press heavily on the mine cover. No force is necessary during any of the above operations.

(e) Lay the mine on top of the safety-pin (already in hole), observing the normal precautions to prevent bridging.
