Description
These fuzes are of the delay, mechanical or electrical, spring-loaded striker type, with a clockwork mechanism. The ChMV 10 has a 10-day delay mechanism, while the ChMV 16 has a 16-day delay mechanism. The only difference in appearance is the numbering on the dials. The numerals indicate days and the divisions between numerals indicate 2 hours each. The clockwork is contained in the mushroom shaped head of the fuze. Geared to the clockwork is the striker-release lever which holds the spring-loaded striker under tension in the narrow base of the fuze. A standard MD 2 detonator assembly or an electric contact cap with leads for wiring into an electrical circuit may be screwed into the base of the fuze and the joint made watertight by a rubber washer. The top of the fuze is closed with a threaded cap, made waterproof by a rubber washer. A glass window is located in the side for reading the time-setting dial. The World War 2 models of this fuze had a cardboard body and were about 3 7/8 inches in length (without the detonator) and 2 inches in diameter. Recent models of this fuze have been found in Korea and have a steel clock housed in a bakelite body. They measure 4 1/4 inches in height and 2 1/8 inches in diameter.
The fuze is used for setting off delayed-action charges in areas given over to an opposing force.
Functioning
After lapse of preset delay period, the striker-release lever trips the spring-loaded striker which either fires the MD 2 detonator assembly or closes the circuit between the two contacts on the top of the contact cap.
