USE: |
|
This mine was designed and developed by the 38th Field Park Co. of the Royal Engi-neers, and is now being manufactrured by them on a large scale. |
|
COMPONENTS: |
|
The mine consists of two principal components: the loaded mine body, and the fuze unit. |
|
(a) Mine Body: The mine body consists of a wooden box with a hinged cover. A bulk-head constructed in the box forms two compartmens, the front one empty, the rear containing the explosive charge and primer. Holes are drilled in the front of the box and in the bulkhead to allow insertion of the percussion igniter. A slot cut in the front of the box lid fits downover the end of the igniter, and two small staples in the lid recive the arming pin which also passes through the hole in the igniter pin. Pressure on the lid will force out the igniter pin and fire the charge. |
|
(b) Fuze Unit: The unit consists of a standard British Percussion Igniter Mk III (See Page 71), a small length of orange instantaneous fuse, a No. 27 detonator, and a C.E. or Guncotton primer. Removal of the igniter pin allows the striker to hit the percussion cap, which ignites the orange instantaneous fuse. The fuse, in turn, sets off the No. 27 detonator, firing the primer and the main charge. |
|
ASSEMBLY & ARMING: |
|
Lay mine in ground and place two 4 oz. charges of Nobel's "808" in the after com-partment. Inspect igniter to maker certain pin is securely in position, then insert short length of orange instantaneous fuse adapter. Crimp a No. 27 detonator over other end of orange fuse, and insert the assembly in the holes provided in the mine body. Place a C.E. or Guncotton primer between the two charges of explosive and insert the No. 27 detonator in the primer. Close the lid of the mine, and insert the arming pin through the staples on the bottom of the lid and the hole in the igniter pin. |
|
NEUTRALIZATION: |
|
To neutralize this mine, remove the arming pin, after making certain that the igniter pin is securely in position. Open the mine lid, and withdraw the fuze assembly from the mine. Separate the igniter from the detonator by cutting the length of orange fuse joining them. Remove the primer, and the explosive charges if desired. |
|
REMARKS: |
|
1. This mine is similar in action and apparance to the German SchuMine. |
