A safety apparatus to safe or to arm and fire a munition, utilizes a rotor containing an aligned adjacent firing pin and detonator in holes extending completely through the rotor perpendicular to the axis. A first explosively powered piston actuator, when fired, will unlock the rotor and enable a second explosively powered piston actuator, when fired, to rotate the rotor to align the detonator with an explosive charge and to cause a firing pin to fire the detonator. The detonator will fire a transfer lead which, in turn, will fire the main charge. As assembled, a third explosively powered piston actuator is aligned with the detonator and, when fired, will cause the detonator to explode and translate the rotor with part of the axis extending out of the munition where it is held in this position to indicate a safe condition.

Apparatus for a portable munition comprising: (a) a rotor having a circular shape and opposed pivot means extending from the center thereof and having a pair of aligned connected retaining holes extending completely through said rotor, in a plane perpendicular to a pivot axis through the pivot means

Apparatus for a portable munition comprising: (a) a rotor having a circular shape and opposed pivot means extending from the center thereof and having a pair of aligned connected retaining holes extending completely through said rotor, in a plane perpendicular to a pivot axis through the pivot means; with said motor having a bar attached thereto as a portion containing a pivot axis with the bar extending radially outward from the pivot axis and in a plane perpendicular to the pivot axis; (b) a detonator and firing pin mounted within the aligned connected retaining holes in said rotor with the retaining holes being dimensioned to fit said detonator and to slideably fit said firing pin respectively; (c) an enclosure having circular shaped interior rotor space oriented and dimensioned to accommodate said rotor, said rotor being pivotably mounted therein by the opposed pivot means; and having interior base space interconnected to the rotor space adjacent to the axis of said rotor containing the attached bar; and having an outside opening through a wall of said enclosure adjacent said rotor; (d) a cam located within the base space having first guide means within the base space relative to said enclosure with the first guide means and the cam dimensioned located and arranged such that said cam can be guided along a linear first guide path by the first guide means, which is located in a guide plane perpendicularly oriented to the pivot axis, with the first guide path extending from a first location which is more distant from the pivot axis than said rotor, thence along a line adjacent to the pivot axis and near said rotor to a second location, which is beyond said rotor; with the first guide path, said cam, said rotor and the bar dimensioned and located such that as said cam moves from said first location to said second location, said cam will strike the bar only, and cause said rotor to rotate from a first angular position to a second angular position relative to said enclosing means; and with the retaining holes within said rotor oriented with respect to said enclosing means such that with said rotor located in said second angular position, relative to said enclosing means, said retaining holes are oriented generally parallel to said first guide path with the opening for said firing pin retaining hole facing in the general direction of the first position of the first guide path; (e) first rotor stop means comprising an extension from said enclosure within said base space arranged to prevent said rotor from rotating beyond the second angular position with respect to said enclosure; (f) first actuator means located within the base space and attached to said enclosure adjacent to said cam, when said cam is in said first position in said first guide path; and first actuator means arranged such that when activated said first actuator means can drive said cam along said first guide path from said first position to said second position; (g) a tang extending from said cam along a line generally parallel to said pivot axis and directed toward said rotor, with said tang offset from said first guide path toward said pivot axis; having said tang, said cam, said bar, said first guide path, and said firing pin dimensioned and located such that, as said cam traverses the first guide path from the first position to the second position said tang will be carried along a tang path which is parallel to the first guide path but which will intersect the pivot axis, such that after said cam has struck the bar and rotated said rotor to the second angular position; said tang will then strike the end of said firing means facing towards the first position of the first guide path and drive said firing pin against and explode said detonator; (h) said enclosure outside opening being aligned with said detonator when said rotor is located in the second angular position; (i) explosive means located outside the enclosure adjacent the outside opening arranged such that, when said rotor is located in the second angular position, a detonator explosion will cause said explosive means to explode.
