Magazine safety and ejector

Claim 2

A magazine safety for a semi-automatic double action firearm having a magazine receiver, a cartridge magazine removeably fitted therein, and a cartridge extractor and wherein a firing pin is cocked and released for firing by a trigger bar pivotably connected to a trigger and resiliently urged into releasable engagement with said firing pin, said magazine safety comprising: camming means comprising an elongated arm pivotably attached at one of its ends to the frame of said firearm and engaging said trigger bar at a point intermediate the ends of said arm for movement of said trigger bar out of engagement with said firing pin; resilient means operatively connected between said frame and said camming means and rotating said camming means about its axis of rotation thereby holding said trigger normally out of engagement with said firing pin; and restraining means comprising a lip positioned on said magazine to engage the end of said arm remote from its said attached end and thereby restrain said camming means from disengaging said trigger bar and said firing pin, when said magazine is seated in its operational position in said magazine receiver.

Claim 3

A magazine safety as defined by claim 1 wherein said camming means is positioned in the path followed by a cartridge extracted from the firing chamber of said firearm by said extractor, and in cooperation with said extractor ejects said cartridge from said firearm.

Claim 4

A magazine safety as defined by claim 1 wherein: said lip holds said arm in alignment with the path followed by a cartridge extracted from the firing chamber of said firearm by the extractor of said firearm when said magazine is seated in its operational position in said magazine receiver; and said arm is adapted in cooperation with said extractor to eject said cartridge from said firearm.

Claim 5

A magazine safety as defined by claim 3 wherein: said arm is rotatably mounted to said frame by means of a pin passing transversely through said frame and said arm; and said resilient means comprise a torsion spring mounted on said pin and having one of its legs anchored to said frame and the other of its legs anchored to said arm.

Claim 6

In combination with a semi-automatic double-action firearm comprising a barrel secured to a frame and containing a firing chamber, a slide mounted to said frame for sliding motion axial of said barrel, a trigger pivotably mounted to said frame, a firing pin disposed within said frame for motion axial of said barrel and having a firing pin sear extending therefrom, a compression spring positioned between said frame and said firing pin, an elongated trigger bar having one of its ends pivotably attached to said trigger and a trigger bar sear on its other end adapted for releasable engagement with said firing pin sear, and having a lobe formed thereon intermediate its said ends, a rail mounted to said frame extending longitudinally of said barrel, resilient means acting on said trigger bar urging said lobe thereof into releasable sliding contact with said rail and urging said trigger bar sear into engagement with said firing pin sear, a magazine for cartridges, and a magazine receiver in said frame adapted to receive and releasably retain said magazine in a seated position, wherein said cartridges are fed into said firing chamber by operation of said slide, a magazine safety comprising: camming means operatively mounted to said frame and effectively engaging said trigger bar for movement of said trigger bar sear out of engagement with said firing pin sear; resilient means operatively connected between said frame and said camming means and urging said camming means to hold said trigger bar sear normally out of engagement with said firing pin sear; and restraining means associated with said magazine restraining said camming means from disengaging said trigger bar sear and said firing pin sear when said magazine is in said seated position in said magazine receiver.

Claim 7

In combination with a semi-automatic double-action firearm comprising a barrel secured to a frame and containing a firing chamber, a slide mounted to said frame for sliding motion axial of said barrel, a trigger pivotably mounted to said frame, a firing pin disposed within said frame for motion axial of said barrel and having a firing pin sear extending therefrom, a compression spring positioned between said frame and said firing pin, an elongated trigger bar having one of its ends pivotably attached to said trigger and a trigger bar sear on its other end adapted for releasable engagement with said firing pin sear, and having a lobe formed thereon intermediate its said ends, a rail mounted to said frame extending longitudinally of said barrel, resilient means acting on said trigger bar urging said lobe thereof into releasable sliding contact with said rail and urging said trigger bar sear into engagement with said firing pin sear, a magazine for cartridges, and a magazine receiver in said frame adapted to receive and releasably retain said magazine in a seated position, wherein said cartridges are fed into said firing chamber by operation of said slide, a magazine safety comprising: camming means operatively mounted to said frame and effectively engaging said trigger bar for movement of said trigger bar sear out of engagement with said firing pin sear; resilient means operatively connected between said frame and said camming means and urging said camming means to hold said trigger bar sear normally out of engagement with said firing pin sear; and restraining means associated with said magazine restraining said camming means from disengaging said trigger bar sear and said firing pin sear when said magazine is in said seated position in said magazine receiver.

Claim 8

The combination defined by claim 5 wherein: said camming means comprise a cam rotatably mounted to said frame; and said resilient means comprises a spring adapted to rotate said cam about its axis of rotation, thereby urging said trigger bar sear out of engagement with said firing pin sear.

Claim 9

The combination defined by claim 6 wherein: said cam comprises an elongated arm pivotably attached at one of its ends to said frame and positioned to engage said trigger bar at a point intermediate the ends of said arm; and said restraining means comprises a lip formed on said magazine and engaging the end of said arm remote from its said attached end when said magazine is in said seated position in said magazine receiver.

Claim 10

The combination defined by claim 7 wherein: said lip holds said arm in alignment with the path followed by a cartridge extracted from the firing chamber of said firearm by the extractor of said firearm when said magazine is in said seated position in said magazine receiver; and said arm is adapted in cooperation with said extractor to eject said cartridge from said firearm.

Claim 11

The combination defined by claim 8 wherein: said arm is rotatably mounted to said frame by means of a pin passing transversely through said frame and said arm; and said resilient means comprises a torsion spring mounted on said pin and having one of its legs anchored to said frame and the other of its legs anchored to said arm.
