Abstract
Abstract A portable motor vehicle visual warning indicator is comprised of a base, one or more pair of wind driven cups or veins pivotally mounted on the base for rotation about the base, one or more mirrors pivotally mounted on the base driven by the cups, and daylight reflective means connected to and driven by the cups. Optionally, the indicator may further incorporate additional features such as a magnetic base to secure the device to a metalic portion of the motor vehicle, and a switch activated lamp wherein the switch is periodically actuated by means connected to the rotating cups.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
219 words
A portable motor vehicle visual warning indicator comprising in combination: a base; a support bracket attached to said base; a vertically oriented rotatable shaft, one end of which is mounted in said base; said shaft extending upwardly through said support bracket and terminating above said support bracket; a plurality of pairs of wind driven cups mounted on and extending horizontally outward from said rotatable shaft and above said support bracket, such that when said cups are subjected to a relative wind, they will cause said rotatable shaft to rotate; each pair of said wind driven cups mounted such that one of its members is mounted on the opposite side of said shaft from the other member; mirror means mounted on and extending horizontally outward from said rotatable shaft such that said mirror means are caused to rotate when said wind driven cups are driven by a relative wind; daylight reflective means connected with and driven by said wind cups; a tab attached to each cup of at least one pair of said wind driven cups, the plane of said tabs being substantially tangential to the circumference of rotation of said cups; daylight reflective means connected with said tabs; said base constructed in part of a magnetic material for securing said apparatus to a metallic portion of a motor vehicle.

Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said daylight reflective means comprises a coating of daylight reflecting paint on said cups and said tabs.
Claim 4
Dependent Claim
68 words
The apparatus of claim 1 wherein said apparatus further includes: a lamp mounted on said base; a battery for supplying electrical power to said lamp mounted on said base; switch means connecting said battery to said lamp; switch activating means mounted on said rotatable shaft and actuated by the rotation of said shaft caused by said wind driven cups for periodically actuating said switch, thereby lighting said lamp.
Claim 5
Dependent Claim
26 words
The apparatus of claim 1 further including adjustable pressure means engaging said rotatable shaft for controlling the speed of rotation of said shaft and said cups.
Claim 6
Dependent Claim
26 words
The apparatus of claim 3 further including adjustable pressure means engaging said rotatable shaft for controlling the speed of rotation of said shaft and said cups.
