Timing mechanism for controlling the charging of a battery in an electronic artillery fuse

A battery for an electronic artillery fuse, the battery being activated in response to the release of electrolyte contained in the battery, the battery comprising:

• a rupturable ampoule containing the electrolyte, the ampoule being rupturable in response to contact with a rupturing surface of the battery, the ampoule normally held in mutually spaced relationship to the rupturing surface;
• a restraining member applying a yieldable restraining force for opposing inertia applied to the fuse to maintain the mutually spaced relationship, the restraining force being yieldable against inertia greater than a predetermined value to permit the ampoule and the rupturing surface to approach one another;
• a timing device for increasing a time period that the inertia of predetermined value must be applied for the ampoule and the rupturing surface to contact one another;
• and
• an ampoule holding body in which the ampoule is mounted, the ampoule holding body normally secured against movement to prevent the ampoule from approaching the rupturing surface, a release body arranged for releasing the ampoule holding body in response to movement of the release body by a predetermined distance in a first direction under the influence of an impulse, the timing device arranged to constrain the release body to rotate about an axis defined by the first direction as the release body travels in the first direction, for increasing a time period required for the release body to travel the predetermined distance.
