Abstract
Abstract A hand firearm has a breech block pivotally mounted in the frame so as to be pivotable downwardly from a closed position to a loading position. The breech block has a firing pin mounted therein which is actuated by an armature of an electro-magnet also disposed in the breech block. A source of electrical energy in the form of a removable unit is disposed in the frame and connected electrically to the coil. This electrical connection to the coil is disconnected when the breech block is pivoted downwardly into its loading position so that the electro-magnet can not be energized and thus actuation of the firing pin is prevented.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
In a trigger mechanism for firearms, the combination of a frame, a breech block pivotally mounted in said frame and pivotable downwardly from a closed position to a loading position, a movable firing pin in said breech block, an electromagnet in said breech block having a coil and a movable armature actuated by said coil, said armature drivingly connected to said firing pin to move the same when said coil is energized, means for defining a source of electrical energy in said frame and connected electrically to said coil, and means for disconnecting said electrical connection when said breech block is pivoted into its loading position so that energization of said electro-magnet and thus actuation of the firing pin is prevented.
Claim 2
Dependent Claim
121 words
In a trigger mechanism for firearms, the combination of a frame, a breech block pivotally mounted in said frame and pivotable downwardly from a closed position to a loading position, a movable firing pin in said breech block, an electromagnet in said breech block having a coil and a movable armature actuated by said coil, said armature drivingly connected to said firing pin to move the same when said coil is energized, means for defining a source of electrical energy in said frame and connected electrically to said coil, and means for disconnecting said electrical connection when said breech block is pivoted into its loading position so that energization of said electro-magnet and thus actuation of the firing pin is prevented.
Claim 3
Dependent Claim
76 words
In a trigger mechanism as claimed in claim 1 wherein said frame has a handle, a trigger comprising a leaf spring mounted on said handle, and means in said handle defining a light-sensitive device having a light beam in the path of movement of said trigger so that interrupting of the light beam when said trigger is actuated sends a pulse to said electrical energy source means to energize the electro-magnet and actuate the firing pin.
Claim 4
Dependent Claim
31 words
In a trigger mechanism as claimed in claim 1 wherein there is a barrel mounted on said frame, said electrical energy source means comprising a removable unit disposed below said barrel.
Claim 5
Dependent Claim
19 words
In a trigger mechanism as claimed in claim 3 wherein said electrical energy source means comprises a plug-contact strip.
Claim 6
Dependent Claim
47 words
A trigger mechanism as claimed in claim 2 wherein said trigger leaf spring has one end attached to said handle and another end freely movable, and means engageable with said trigger element other end for adjusting the movement of said trigger required to interrupt said light beam.
Claim 7
Dependent Claim
31 words
In a trigger mechanism as claimed in claim 5 and light means on said frame connected to said electrical energy source means for indicating visually a pulse generated by said trigger.
