Publication number: 20150089854Abstract: An action lock for a Modern Sporting Rifle pump action firearm is pivotably mounted within the lower receiver of the rifle and has a stop surface that engages a contact surface on the bolt carrier when the bolt carrier is in battery. A cam on the hammer or the trigger engages a cam surface on the action lock when the hammer is released by a pull of the trigger. Cam action rotates the action lock out of engagement with the bolt carrier, unlocking it and allowing the fore end grip to be pumped to cycle the action and extract and eject the spent casing and strip and chamber a new round.Type: ApplicationFiled: October 2, 2013Publication date: April 2, 2015Applicant: Smith & Wesson Corp.Inventor: David S.

Patent number: 8985005Abstract: A mechanism for a repeating firearm has a body pivotably mounted within the receiver and movable between a first position where it blocks motion of the bolt carrier, and a second position where it engages either the trigger or the hammer to prevent discharge. In operation the body is moved from the first position to the second to release the bolt carrier, which moves into battery. The body is then allowed to move out of the second position toward the first position. The rife may be discharged by a pull of the trigger, and the bolt carrier moves out of battery and is arrested by the body before moving back to battery. If the body is maintained in the second position during operation its engagement with the trigger or hammer prevents discharge of the firearm.Type: GrantFiled: December 19, 2013Date of Patent: March 24, 2015Assignee: Smith & Wesson Corp.Inventors: Jason Dubois, David S.

Patent number: 8966802Abstract: A trigger assembly has a sear with a stop surface engageable with a reciprocating component for holding the reciprocating component in a cocked configuration. The sear also has a sear cam engageable with a lever movably mounted within the assembly. A trigger is movable into and out of engagement with the lever. Pulling the trigger moves it out of engagement with the lever and releases the sear. A trigger return pendulum has a trigger cam engageable with the trigger, a lever cam engageable with the lever, and a head cam follower engageable with the reciprocating component. Motion of the reciprocating component acting through the head cam follower of the trigger return pendulum forces the lever cam into engagement with the lever and the trigger cam into engagement with the trigger to return the lever and the trigger to a configuration of engagement between the trigger and the lever.Type: GrantFiled: November 14, 2013Date of Patent: March 3, 2015Assignee: Smith & Wesson Corp.Inventor: David S.
