ABSTRACT:
A backup mechanism for a fuze includes a plate having a slot therein which is freed up during the arming of the firing pin screw. A weight link having a pair of legs spaced along the slot is mounted for movement in the slot. A trip link is pivotally mounted to the plate and has a first leg for frictional engagement against the side of the first weight link leg. The second leg of the trip link is biased for rotation by a leaf spring. Another leaf spring engages against the second leg of the weight link for urging it in a movement direction along the slot. Friction between the first legs of the trip and weight links and/or the upward pull force of the ribbon hold the weight link in an initial position after fuze arming. When exposed to inertia, and/or the absence of upward ribbon pull force the weight link moves. This causes disengagement between its first leg and the first leg of the trip link. The spring rotates the strip link so that its first leg now pushes the weight link along the slot. The further leaf spring engaged against the second link of the weight link also pushes the weight link along the slot. A pin connected to the weight link is engaged with the weight of a standard fuze to enhance the pushing force on the weight.
