ABSTRACT:
A safety mechanism for the trajectory for a projectile fuse.
The mechanism uses a symmetrical escapement of the cylindrical dead-beat type which does not comprise an inlet lip. The balance comprises two cheeks located one on each side of the escapement wheel, a cylindrical sector being provided on each cheek. Impulses provided by the escapement wheel are transmitted alternately to one of the two sectors then to the other sector, thereby causing the balance to oscillate first in one direction and then in the opposite direction.
