In a firing mechanism for Gatling-type guns, separate safing and firing cams are located at a firing position coinciding with a notch in an annular safing ring against which cocking levers ride to maintain their firing pins in pre-cocked conditions. To safe the firing mechanism, the safing cam is positioned to bridge the notch and maintain the firing pins pre-cocked as they revolve through the firing position. When the mechanism is armed, a cocking ramp surface of the firing cam is then positioned to cam the cocking levers rearwardly, cocking their firing pins. Immediately thereafter, the cocking levers drop off a firing cam sear corner into the notch now exposed by the safing cam to successively fire off ammunition rounds.

A firing mechanism for a Gatling-type gun comprising in combination: A. a housing; B. a rotor rotatable with respect to said housing about a longitudinal axis; C. a plurality of spring-biased firing pins mounted by said rotor in angularly spaced relation, each said firing pin including a cocking lever; D. an annular safing ring carried by said housing and having an planar cam surface interrupted by a notch coinciding with an angular firing position of said rotor, said cocking levers bearing against said planar cam surface during rotation of said rotor to maintain said firing pins in pre-cocked conditions; E. a firing cam mounted to said housing for movement between safe and armed positions, said firing cam having 1) a cocking ramp surface terminating at a sear corner longitudinally aligned with said safing ring notch, and 2) a first actuating cam; F. a safing cam mounted to said housing for movement between safe and armed positions, said safing cam having 1) a bridging cam surface longitudinally aligned with said safing ring notch, and 2) a second actuating cam; G. an actuator mounted by said housing, said actuator having quiescent and actuated states; H. an actuating link mounted for movement by said actuator between safe and armed positions and carrying a cam driver in joint engagement with said first and second actuating cams; I. with said actuator in said quiescent state, said link, said safing cam and said firing cam assume their respective safe positions with said bridging cam surface spanning said safing ring notch in substantial coplanar relation with said planar cam surface to maintain said cocking levers in said pre-cocked positions during movement past said notch and with said cocking ramp surface disposed in longitudinally displaced relation to said planar cam surface, and with said actuator in its actuated state, said link, said safing cam and said firing cam assume their respective armed positions with said bridging cam surface in longitudinally displaced relation to said safing ring notch and with said cocking ramp surface disposed to successively divert said cocking levers from said planar cam surface and fully cock said firing pins, said cocking levers successively dropping off said sear corner into said safing ring notch, thereby allowing said cocked firing pins to spring longitudinally forward to fire ammunition rounds.
