Firing mechanism for high rate of fire revolving battery gun

Claim 2

A revolving battery gun comprising: a relatively stationary housing; a relatively movable rotor journaled for rotation within said housing; said rotor having a plurality of barrels disposed in an annular row, and a like plurality of bolt guide ways, each in alignment with a respective barrel, and a like plurality of bolts, each disposed in a respective guideway; each bolt having a laterally extending cam follower and a longitudinally extending cam follower; said housing having an inner peripheral cam track receiving each of said bolt laterally extending cam followers, for providing each bolt with longitudinal movement along its respective guideway as said rotor rotates, and having an inner annular cam track receiving each of said bolt longitudinally extending cam followers, for providing each bolt with rotational movement within its respective guideway during the rotation of said rotor.

Claim 3

A gun according to claim 1 wherein: said bolt comprises a longitudinally telescoping, and rotationally interlocked assembly of a forward body having said laterally extending cam follower and an aft unit having said longitudinally extending cam follower.

Claim 4

A gun according to claim 2 wherein: said bolt body has a longitudinal bore therethrough with a lateral aperture, and a mainspring and a firing pin with a forward penetrator are disposed in said bore, said firing pin having a laterally extending cocking pin projecting through said aperture, a cocking pin control slot formed in each of said bolt guideways for receiving the distal end of the cocking pin of the respective bolt, said control slot having an aft, longitudinally extending cocking portion, a forward longitudinally extending fire portion, and an intermediate, transverse portion, having a forward-searing surface and an aft resetting camming surface; said lateral opening of said bolt body having a forward surface which in conjunction with said control slot cocking portion precludes forward movement of said cocking pin and projection of said penetrator from said bolt body until said bolt body has been rotated into lock.

Claim 5

A gun according to claim 2 wherein: the longitudinally extending cam follower of each said aft unit is mounted on an arm extending laterally from said unit and is journaled on an axis spaced from the axis of said unit, the distal end of said arm being pivotally coupled to the next adjacent arm, the pivot being journaled on an axis spaced from the axis of said next adjacent unit.

Claim 6

A gun according to claim 1 wherein: said annular cam track has two alternative configurations, one being circular, the other having a rise and fall, said one configuration being adapted to preclude any rotation of said bolts, said other configuration being adapted to provide rotational movements to said bolts.

Claim 7

A gun according to claim 3 wherein: said forward surface of said lateral Opening has a camming portion for camming said cocking pin aft and retracting said penetrator into said bolt body before said bolt body is completely unlocked.
