Abstract
Abstract Trigger or touch-actuated or screw-cap actuated safety device for trigger or touch-actuated or screw-cap actuated mechanisms is provided having a pivotally mounted magnetically responsive bar positioned on the inside of the handle on the rear of the trigger. When the bar is oriented centrally, sufficient movement of the trigger is inhibited to prevent actuation of the device. The bar may be mounted in a non-magnetizable casing. The user of the device, by wearing a magnetic ring, displaces the bar from its central orientation and allows for sufficient movement of the trigger for actuation. The present invention may also be employed to selectively inhibit operation of touch-actuated devices.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
101 words
In a safety device for preventing the unauthorized firing of a weapon having a trigger, a cylinder for holding cartridges to be fired by said weapon, a cylinder rotation means operative in response to movement of said trigger, a hammer, and hammer actuation means, wherein the invention comprises: a magnetic actuable member pivotally mounted with respect to said cylinder rotating means; stop means for preventing said member from pivoting beyond a predetermined arc; and bias means for maintaining said member in a position of the arc for preventing movement of said cylinder rotation means to thereby prevent firing of said weapon.
Claim 2
Dependent Claim
101 words
In a safety device for preventing the unauthorized firing of a weapon having a trigger, a cylinder for holding cartridges to be fired by said weapon, a cylinder rotation means operative in response to movement of said trigger, a hammer, and hammer actuation means, wherein the invention comprises: a magnetic actuable member pivotally mounted with respect to said cylinder rotating means; stop means for preventing said member from pivoting beyond a predetermined arc; and bias means for maintaining said member in a position of the arc for preventing movement of said cylinder rotation means to thereby prevent firing of said weapon.
Claim 3
Dependent Claim
47 words
A safety device as in claim 1 further characterized by said cylinder rotating means comprising a linkage mechanically coupled between said trigger and said cylinder and having a notch formed therein and said magnetically actuable member having an extension thereof for engaging the notch in said linkage.
Claim 4
Dependent Claim
44 words
A safety device as in claim 1 further characterized by said cylinder having a plurality of projections on one end thereof, and said magnetically actuable member being disposed for interfering with said projections on said cylinder to thereby prevent rotation of the said cylinder.
Claim 5
Dependent Claim
41 words
A safety device as in claim 1 further characterized by said cylinder including a plurality of notches formed in one end thereof, and said magnetically actuable member being disposed for engaging said notches so as to prevent rotation of said cylinder.
