US12687354 - Bolt action firearm

A bolt action firearm has an ejector element movable between a forward position in which a portion of the ejector element protrudes from the bolt face and a rearward position rear of the forward position, an ejector restraint element operable in a restraining position to restrain the ejector element to the rearward position and in a release position to enable movement of the ejector element from the rearward position to the forward position, an actuator movable between a first position and a second position such that seating a cartridge case head in an aligned position motivates the actuator from the first position to the second position, and a linkage connecting the actuator to the ejector restraint element and operable in response to movement of the actuator from the first position to the second position to enable movement of the ejector element from the rearward position to the forward position.

The patent describes a bolt action firearm featuring a movable ejector element that can transition between forward and rearward positions, controlled by an actuator linked to an ejector restraint element. This design allows for the efficient seating and ejection of cartridge cases during operation.

Claim 1

1 . A bolt action firearm comprising: a receiver defining a bolt passage; a barrel defining a chamber connected to the receiver; a bolt assembly received in the bolt passage and operable to reciprocate between a forward battery position proximate the barrel and a rearward fully open position; the bolt assembly including a bolt head having a bolt face configured to abut a cartridge case head and receive the cartridge case head in an aligned position for discharge; the bolt head defining an ejector bore having an ejector bore aperture in the bolt face; an ejector element received in the ejector bore and movable between a forward position in which a portion of the ejector element protrudes from the bolt face and a rearward position rear of the forward position; the ejector element being spring biased to the forward position; an ejector restraint element movable between a restraining position and a release position and operable in the restraining position to restrain the ejector element to the rearward position, and when in the release position to enable movement of the ejector element from the rearward position to the forward position; an actuator associated with the bolt face and movable between a first position conflicting with the presence of the cartridge case head in the aligned position, and a second position enabling the cartridge case head in the aligned position, such that seating the cartridge case head in the aligned position motivates the actuator from the first position to the second position; and a linkage connecting the actuator to the ejector restraint element and operable in response to movement of the actuator from the first position to the second position to enable movement of the ejector element from the rearward position to the forward position. a receiver defining a bolt passage; a barrel defining a chamber connected to the receiver; a bolt assembly received in the bolt passage and operable to reciprocate between a forward battery position proximate the barrel and a rearward fully open position; the bolt assembly including a bolt head having a bolt face configured to abut a cartridge case head and receive the cartridge case head in an aligned position for discharge; the bolt head defining an ejector bore having an ejector bore aperture in the bolt face; an ejector element received in the ejector bore and movable between a forward position in which a portion of the ejector element protrudes from the bolt face and a rearward position rear of the forward position; the ejector element being spring biased to the forward position; an ejector restraint element movable between a restraining position and a release position and operable in the restraining position to restrain the ejector element to the rearward position, and when in the release position to enable movement of the ejector element from the rearward position to the forward position; an actuator associated with the bolt face and movable between a first position conflicting with the presence of the cartridge case head in the aligned position, and a second position enabling the cartridge case head in the aligned position, such that seating the cartridge case head in the aligned position motivates the actuator from the first position to the second position; and a linkage connecting the actuator to the ejector restraint element and operable in response to movement of the actuator from the first position to the second position to enable movement of the ejector element from the rearward position to the forward position.
