Abstract
Abstract An light-energy initiated firing system for a firearm in which optical light-conducting fibers extend from a source of high frequency energy to adjacent a cartridge so that energy passes through the fibers will pass into the cartridge and initiate a propellant therein. The firearm cartridge may include a ignition composition (e.g., a primer) position forward of at least part of the propellant and be constructed so that high frequency (e.g., laser) energy will pass into the cartridge and initiate the forward-positioned propellant. The system includes safety systems for interrupting the energy path to prevent primer initiation when the action of the firearm is not in battery or when such initiation otherwise is undesired.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
A firearm comprising a frame, a barrel, a moveable slide, a firing system having a laser, and a safety system, the safety system comprising: a first means for preventing a laser beam from reaching a propellant in the barrel, the first means for preventing comprising a shutter movably positioned in a path of the laser beam and means for moving the shutter based upon relative position of the slide relative to the frame; a second means for preventing the laser beam from reaching the propellant in the barrel, the second means being deactivated upon the slide being located at a battery position relative to the barrel.
Claim 2
Dependent Claim
106 words
A firearm comprising a frame, a barrel, a moveable slide, a firing system having a laser, and a safety system, the safety system comprising: a first means for preventing a laser beam from reaching a propellant in the barrel, the first means for preventing comprising a shutter movably positioned in a path of the laser beam and means for moving the shutter based upon relative position of the slide relative to the frame; a second means for preventing the laser beam from reaching the propellant in the barrel, the second means being deactivated upon the slide being located at a battery position relative to the barrel.
Claim 3
Dependent Claim
24 words
A firearm as in claim 1 wherein the first means comprises means for selectively moving the shutter comprising a safety switch on the frame.
Claim 4
Dependent Claim
72 words
A firearm as in claim 1 wherein the second means comprises the laser being fixedly connected to the frame with an output and, a light guide connected to the slide having an output at the barrel and an input, the light guide input being aligned with the laser output when the slide is at the battery position and, misaligned with the laser output when the slide is not at a battery position.
Claim 5
Dependent Claim
121 words
A firearm comprising a frame, a barrel, a movable slide, a firing system having a laser, and a safety system, the safety system comprising: a laser beam blocker movably positioned in a path of a laser beam between the laser and a chamber of the barrel, the laser beam blocker comprising a shutter connected to a spring biased shutter moving member, the shutter moving member being movably mounted on the slide; and means for moving the blocker based upon relative movement of the slide relative to the frame, the means for moving comprising the frame having a depression for allowing a portion of the moving member to be located therein at a predetermined position of the slide relative to the frame.
Claim 6
Dependent Claim
121 words
A firearm comprising a frame, a barrel, a movable slide, a firing system having a laser, and a safety system, the safety system comprising: a laser beam blocker movably positioned in a path of a laser beam between the laser and a chamber of the barrel, the laser beam blocker comprising a shutter connected to a spring biased shutter moving member, the shutter moving member being movably mounted on the slide; and means for moving the blocker based upon relative movement of the slide relative to the frame, the means for moving comprising the frame having a depression for allowing a portion of the moving member to be located therein at a predetermined position of the slide relative to the frame.
Claim 7
Independent Claim
120 words
A method of manufacturing a firearm, the firearm having a laser firing system and a safety system, the method comprising steps of: positioning a movable blocker in a path of a laser beam in the laser firing system; providing means to move the blocker including connecting the blocker to a first member of the firearm and having the blocker contact a second member of the firearm such that upon movement of the first and second members relative to each other the blocker is moved; and positioning a manually operable safety proximate the blocker to enable a user to manually move the blocker by means of the manually operable safety without moving the first and second members relative to each other.
Claim 8
Independent Claim
120 words
A method of manufacturing a firearm, the firearm having a laser firing system and a safety system, the method comprising steps of: positioning a movable blocker in a path of a laser beam in the laser firing system; providing means to move the blocker including connecting the blocker to a first member of the firearm and having the blocker contact a second member of the firearm such that upon movement of the first and second members relative to each other the blocker is moved; and positioning a manually operable safety proximate the blocker to enable a user to manually move the blocker by means of the manually operable safety without moving the first and second members relative to each other.
Claim 9
Dependent Claim
40 words
A method as in claim 5 wherein the step of positioning the blocker comprises locating the blocker such that a portion of the blocker is located to be moved in front of an end of a fiber optic light guide.
Claim 10
Dependent Claim
31 words
A method as in claim 5 wherein the step of providing means to move the blocker comprises connecting a spring to the blocker to bias the blocker in a predetermined direction.
Claim 11
Dependent Claim
33 words
A method as in claim 5 wherein the step of providing means to move the blocker comprises forming a depression in the second member for a portion of the blocker to extend into.
