DESCRIPTION |
|
This is a chemical, long delay pistol. A plunger (4) is located in the upper portion (1) of the pistol body. A plunger spring (8) bears against the plunger shoulder. When the safety fork (3) is in place, the plunger (4) is held up, thereby keeping the plunger spring under compression. An acetone filled glass ampoule (5) rests beneath the plunger (4). Beneath the ampoule (5) are celluloid discs (9) in which the striker screw (10) is coun-tersunk. The striker (12) is held in place against the cocked striker spring (11) by means of the striker screw (10). A rubber disc (6) between the plunger (4) and am-poule (5) keeps the acetone from leaking out through the plunger cavity. |
|
OPERATION |
|
When the bomb is dropped, the safety fork (3) is removed, thereby allowing the com-pressed plunger spring (8) to force the plunger (4) down. The force of this blow breaks the ampoule (5), thereby permitting acetone to flow down onto the celluloid discs (9). The acetone then softens the celluloid sufficiently so that the countersunk striker screw (10) can be pulled free by the cocked firing spring (11). The spring then forces the striker (12) onto the detonator, initiating detonation of the bomb. |

COMPONENTS OF EXPLOSIVE TRAIN |
|
|
ARMING TIME |
The pistol functions at the instant the safety fork is withdrawn. |
|
REMARKS |
|
1. The delay setting times are similar to those for the No. 37 Pistol. Maximum delay is about 144 hours. |
|
2. It should be noted that the glass ampoule is broken at the instant of release. |
|
3. Since the acetone container is made of glass, the ampoule may break and the pistol may function, even if dropped "Safe". |
|
4. No anti-withdrawal device is known to be fitted to the Mk I pistol. However, future pistols of later design may be so equipped. |
