Abstract
Abstract The release of the safety button of a firearm is indicated by the lighting of a lamp and/or the sounding of a buzzer. Movement of the safety button is detected by a resiliently positioned coil of wire which acts as a switch contact to supply electrical energy from a battery to the indicator upon release of the safety.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
232 words
A safety indicator for a weapon having a metal housing part in which a movable metal safety member is positioned, said safety member being movable between a release position in which the safety is disengaged and an engaged position in which the safety member is engaged and the weapon will not operate, comprising: an indicator means mounted on the weapon along an upper surface thereof, when in the normal horizontal firing position, for producing an indication whenever it is activated by electrical energy, said indicator means further includes a delay means that produces an electrical delay signal a predetermined period after the indicator means is activated, and an alarm that is activated in response to the electrical delay signal; a source of electrical energy; a safety release detector switch located adjacent the safety of the weapon, said detector switch including said safety member and a first resilient wire which is in electrical contact with the safety member when the safety member is in the release position and is out of contact with the safety member when it is in the engaged position, and a second wire connected to said metal housing, said first wire being insulated from said housing, said detector switch, indicator means, source of electrical energy and metal housing part all being connected in series such that the indicator means is activated when the safety member contacts the first wire.

Claim 3
Dependent Claim
23 words
A safety indicator as claimed in claim 1 wherein the first resilient wire has a coiled portion positioned to contact the safety member.
Claim 4
Dependent Claim
15 words
A safety indicator as claimed in claim 1 wherein said indicator means is a lamp.
Claim 5
Dependent Claim
16 words
A safety indicator as claimed in claim 1 wherein said alarm means is an audio alarm.
Claim 6
Dependent Claim
255 words
A safety indicator for a firearm having a stock of insulating material and a metal housing part in which an axially slidable metal safety button is positioned, said safety button being slidable between a release position in which the safety button is disengaged and an engaged position in which the safety button is engaged and contacts a portion of a trigger mechanism of the firearm such that it will not operate, comprising: a battery for supplying electrical energy, said battery having first and second terminals and being located in a cavity in the stock of the firearm; a safety release detector switch in the form of a first resilient wire with a flat coiled portion at its end which is in electrical contact with the safety member when the safety member is in the release position and is out of contact with the safety member when the safety member is in the engaged position, said wire being electrically connected to the first terminal of said battery; an indicator lamp mounted on the firearm along an upper surface thereof, when in the normal horizontal firing position, said indicator lamp being connected between the second terminal of the battery and the metal housing part such that said lamp is turned on whenever the safety is in the release position; a delay means connected across said indicator lamp for producing an electrical delay signal a predetermined period of time after said lamp is turned on; and a buzzer that is activated in response to the electrical delay signal.
