ABSTRACT:
An emergency signalling device which will transmit a code signal by means of spaced reflective members rotatably mounted upon a member which may be driven by air currents. The device more particularly comprises a rotatably mounted surface such as a hemisphere upon the convex surface of which are provided spaced reflective areas of differing dimensions which will reflect flashes of different duration when exposed to sunlight corresponding to a recognizable code to transmit an emergency message such as S.O.S. Means are provided upon the said surface to permit adjustment of rate of rotation in accordance with the velocity of air currents to which it is exposed.
