摘要：
A FIRE CONTROL SYSTEM FOR AN AUTOMTIC FIREARM CAPABLE OF BEING MANUALLY SET TO SELECTIVELY PROVIDE AUTOMATIC CLOSED-BOLT OPERTION, AUTOMATIC OPEN-BOLT OPERATION AND SEMIAUTOMATIC CLOSED-BOLT OPERTION. THE FIREARM CAN BE SET TO THESE MODES OF OPERATION BY MOVING A MODE-SELECTOR KNOB LOCATED ON THE EXTERIOR OF THE FIREARM. THE KNOB MOVES A CAM WHICH COOPERATES WITH SEARS PARTS TO SET THE MODE OF OPERATION. A HEAT SENSING DEVICE IS POSITIONED IN THE BARREL OF THE FIREARM NEAR THE FIRING CHAMBER TO SENSE THE TEMPERTURE OF THE BARREL AND WHEN THIS TEMPERATURE REACHES A POINT AT WHICH COOK-OFF OF A CARTRIDGE IS INCIPIENT A MECHANISM IS ACTUATED TO AUTOMATICALLY SWITCH THE FIREARM TO ITS AUTOMATIC OPEN-BOLT MODE OF OPERATION. THE FIREARM IS CAPABLE OF FIRING CASELESS AMMUNITION.
