Abstract
Abstract A rotating beacon is provided which is in the shape of a pyramid having upwardly and inwardly extending corners defining a plurality of sides. The corners provide a discernible reduction in light thus giving a pattern of intermittent flashing of light from the side panels of the pyramid member upon rotation. The enclosed pyramid member tapers upwardly at an angle of substantially 20* directing either reflected or projected light in an upwardly and outwardly direction. The bottom of the pyramid is enclosed with a reflective member and a gearwheel reinforcing the bottom supports the pyramid member and allows the same to be rotated by an electric motor.

Claim 3
Dependent Claim
20 words
The warning device of claim 1 wherein said rotating means comprises an electric motor for continuously driving said pyramid member.
Claim 4
Dependent Claim
28 words
The warning device of claim 1 wherein said bottom includes an opening concentric with said gearwheel, and a light extending through said opening to illuminate said pyramid member.
Claim 5
Dependent Claim
44 words
