20100170129 | FIREARM HAVING NONMETALLIC COMPONENTS - A firearm comprising a frame, a barrel with a firing axis connected to the frame, a cylinder pivotally attached to the frame and positioned within an opening in the frame and having a plurality of firing chambers sized to receive a cartridge, and a firing mechanism including a trigger attached to the frame to actuate the firing mechanism, wherein the frame is substantially nonmetallic and includes at least one metal insert having a polymer over-molding. A cylinder retaining mechanism selectively retains the cylinder in a first position within a window in the frame and comprises a biasing pin operatively attached to a yoke and which is oriented in a direction substantially transverse to the bore axis when the cylinder is in the first position. | 07-08-2010 |
20100192440 | FIREARM HAVING NONMETALLIC COMPONENTS AND AN AMBIDEXTROUS CYLINDER RELEASE LEVER - A polymeric revolver including a frame, a cylinder mounted in a rectangular aperture in the frame, a cylinder retaining mechanism and a cylinder releasing mechanism is provided. The cylinder retaining mechanism includes two assemblies: (1) an extractor, locking bolt and locking bolt retainer that house an extractor rod spring, and (2) a ratchet hub driver, hub drive center pin and central pin plate that house a ratchet drive spring. The two assemblies are biased toward one another forming a locking engagement of the extractor and the ratchet hub driver. The locking engagement is enhanced by a star-shaped configuration of grooves and ridges on the extractor and ratchet hub driver, respectively. The cylinder releasing mechanism includes a cylinder release lever that actuates the hub drive center pin and ratchet hub driver out of locking engagement with the extractor, and an ambidextrous thumb piece that facilitates access to the cylinder release lever. | 08-05-2010 |
20100192441 | FIREARM HAVING NONMETALLIC COMPONENTS AND AN EXTRACTOR YOKE LOCKUP - A polymeric revolver including a frame, a cylinder mounted in a rectangular aperture in the frame via a yoke, and a cylinder retaining mechanism is provided. The cylinder retaining mechanism includes multiple assemblies, which lock the yoke in the cylinder-closed position, including: (1) an extractor, a locking bolt and a locking bolt retainer that house an extractor rod spring and engage a ratchet hub driver, hub drive center pin and central pin plate that house a ratchet drive spring; (2) a star-shaped configuration of grooves and ridges on the extractor and the ratchet hub driver, respectively; (3) a rear taper of the locking bolt that engages a concave recess at the axial center of the rounded groove of the locking bolt recess; and (4) an annular ring that engages an inner wall of an annular opening in a breach face of the frame. | 08-05-2010 |
20100325932 | FRAME-MOUNTED TRIGGER SAFETY AND WELL EXTENSION - A trigger safety for a firearm having a frame and slide. The safety includes a safety assembly frame mountable within the firearm frame. The safety also includes at least one actuator operatively attached to the safety assembly frame, the actuator being capable of selectively moving the safety assembly frame between a first position and a second position. The assembly frame also has an abutment surface. In the first position the abutment surface contacts a trigger bar of the firearm preventing movement of the trigger and discharge of the firearm while allowing the slide to be cycled and in the second position the abutment surface is not in contact with the trigger bar and the firearm can be discharged. | 12-30-2010 |
20110107640 | FIREARM HAVING NONMETALLIC COMPONENTS AND AN AMBIDEXTROUS CYLINDER RELEASE LEVER - A polymeric revolver including a frame, a cylinder mounted in a rectangular aperture in the frame, a cylinder retaining mechanism and a cylinder releasing mechanism is provided. The cylinder retaining mechanism includes two assemblies: (1) an extractor, locking bolt and locking bolt retainer that house an extractor rod spring, and (2) a ratchet hub driver, hub drive center pin and central pin plate that house a ratchet drive spring. The two assemblies are biased toward one another forming a locking engagement of the extractor and the ratchet hub driver. The locking engagement is enhanced by a star-shaped configuration of grooves and ridges on the extractor and ratchet hub driver, respectively. The cylinder releasing mechanism includes a cylinder release lever that actuates the hub drive center pin and ratchet hub driver out of locking engagement with the extractor, and an ambidextrous thumb piece that facilitates access to the cylinder release lever. | 05-12-2011 |
20120167426 | UNITARY SEAR HOUSING BLOCK - A firearm includes a frame having at least one interior receptacle defined by opposed interior walls and having opposed guide rails extending from the opposed interior walls, and at least one modular housing disposed in the receptacle and accommodating at least one operational component of the firearm. The modular housing is defined by opposed sidewalls having opposed guide channels formed therein, the guide channels being configured to selectively engage the guide rails to facilitate the aligning of the modular housing with respect to the interior receptacle. The at least one operational component and the modular housing are pre-assembled together as an integrated unit for drop-in insertion into the receptacle during assembly of the firearm. | 07-05-2012 |
20120167427 | ROTATING AND TRANSLATING EXTRACTOR MECHANSIM - An extractor mechanism for a firearm includes a firearm slide having a pocket, the pocket extending in a longitudinal direction substantially parallel to a firing axis of a firearm and having an opening proximate to a breech face of the slide, and an extractor arm having a body portion and a hook portion, the body portion being disposed at least partially within the pocket and the hook portion extending at least partially out of the opening and having a distal edge sized to engage a cartridge rim, wherein the extractor arm is pivotally and slidably mounted to the slide such that the hook portion is capable of being pivoted toward and away from the firing axis and the extractor arm is capable of translational movement with respect to the slide in a direction substantially parallel to the firing axis. | 07-05-2012 |
20130074391 | DROP SAFETY FOR A FIRING PIN OF A FIREARM - A firearm has a firing mechanism that includes a firing pin, a drop safety, a spring mounted to the drop safety and a trigger in mechanical communication with the firing pin and the drop safety. The drop safety includes a roller portion having an outer circumferential surface and an inner opposing wall. When the trigger is actuated, the opposing wall of the drop safety abuts and engages the firing pin in the forward-most axial position thereof, thereby allowing the firing pin to strike a primer of a chambered round of ammunition. In all other configurations, the spring rotationally biases the drop safety so that the outer circumferential surface of the roller portion of the drop safety blocks the forward axial reciprocation of the firing pin, preventing the firing pin from engaging the primer of a chambered round of ammunition. | 03-28-2013 |
20140317981 | Unitary Sear Housing Block - A firearm includes a frame having at least one interior receptacle defined by opposed interior walls and having opposed guide rails extending from the opposed interior walls, and at least one modular housing disposed in the receptacle and accommodating at least one operational component of the firearm. The modular housing is defined by opposed sidewalls having opposed guide channels formed therein, the guide channels being configured to selectively engage the guide rails to facilitate the aligning of the modular housing with respect to the interior receptacle. The at least one operational component and the modular housing are pre-assembled together as an integrated unit for drop-in insertion into the receptacle during assembly of the firearm. | 10-30-2014 |
