Abstract:
1. A warning light system for use with a chain saw having a cutting chain mounted for rotation about a chain guide bar, and providing a chain saw hazard warning light for generating a warning light throughout a chain shot warning zone whenever said cutting chain is in rotational motion about said chain guide bar, said system comprising: a first electric light source for emitting a first light beam in a first direction throughout, and limited to, said warning zone; a second electric light source for emitting a second light beam in a second, opposite direction throughout, and limited to, said warning zone; wherein the first and second electric light sources are energized to emit the first light beam and the second light beam if, and only if, said cutting chain is in rotational motion about said chain guide bar; wherein said warning zone is defined by first and second pairs of planes that diverge in opposite directions from said chain guide bar, said planes being disposed at equal, acute angles to, and on opposite sides of, a plane that includes said chain guide bar, and wherein said chain shot warning zone is configured as a danger zone where flying fragments of a broken cutting chain would go along said first and second directions if a chain shot situation were to occur.
