Safety indicators for guns

Claim 1

A safety indicator device for a gun having a barrel, a stock and a safety mechanism for selectively setting the gun in a first condition for firing or in a second condition to prevent firing, said safety mechanism including a slide member mounted on said gun for movement between first and second positions corresponding respectively to said first and second conditions, said indicator device comprising a first jewel mounted on said gun adjacent said slide member and exposed by said slide member in said first position and covered thereby in said second position, a battery, light bulb and electrical circuit therebetween mounted in said gun, and including switch means cooperatively associated with said slide member for closing said circuit to energize said bulb when said slide member is in said first position, and opening said circuit in said second position, a first light-transmitting conduit means mounted on said gun extending between said light bulb and said jewel thereby to internally illuminate said jewel when said slide member is in said first position, and, second light-transmitting conduit means mounted in said gun to extend from said jewel to a point on the exterior thereof thereby to pick up ambient light to illuminate said jewel in the event of electrical failure with concomitant absence of positive light bulb illumination.
