Abstract
Abstract A light system for directing headlight beams in the direction of vehicle turning in which at least one lamp on the vehicle is trained in each cornering direction and a centrifugally operated switch selectively illuminates the lamps. The switch comprises a hollow body containing a centrifugally displaceable liquid (e.g. mercury) and has upwardly divergent arms each receiving a respective contact in an electrical circuit with the corresponding layer. A central contact may be connected to one pole of the supply network. The switch preferably lies in a vertical plane perpendicular to the direction of travel on the vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A turn-illuminating system for an automotive vehicle comprising a pair of turn-illuminating lamps respectively trained to the right and left sides of said vehicle and substantially fixedly positioned therein; circuit means for selectively energizing said lamps; and switch means responsive to the centrifugal force of an incipient turn of said vehicle to the right and left, respectively, and connected to said circuit means for energizing the corresponding lamp, said switch means including an evacuated tube having a pair of arms interconnected by an arcuate trough receiving a pool of conductive liquid, a pair of contacts in said arms engageable by said pool end respectively connected to said lamps, a central contact continuously engaging said pool, said tube being formed with a surge-suppressing downwardly extending projection above said trough and reaching substantially to the surface of said pool in a quiescent state thereof.
Claim 2
Dependent Claim
142 words
A turn-illuminating system for an automotive vehicle comprising a pair of turn-illuminating lamps respectively trained to the right and left sides of said vehicle and substantially fixedly positioned therein; circuit means for selectively energizing said lamps; and switch means responsive to the centrifugal force of an incipient turn of said vehicle to the right and left, respectively, and connected to said circuit means for energizing the corresponding lamp, said switch means including an evacuated tube having a pair of arms interconnected by an arcuate trough receiving a pool of conductive liquid, a pair of contacts in said arms engageable by said pool end respectively connected to said lamps, a central contact continuously engaging said pool, said tube being formed with a surge-suppressing downwardly extending projection above said trough and reaching substantially to the surface of said pool in a quiescent state thereof.
Claim 3
Dependent Claim
11 words
The system defined in claim 1 wherein said liquid is mercury.
Claim 4
Dependent Claim
46 words
The system defined in claim 1 wherein said trough is an arcuate bight portion receiving said pool in the quiescent state thereof, and said arms are upwardly divergent and upwardly tapering from said bight portion, the contacts of said pair being anchored in said bight portion.
Claim 5
Dependent Claim
23 words
The system defined in claim 3 wherein said central contact is anchored in an outer wall of said bight portion opposite said projection.
Claim 6
Dependent Claim
32 words
The system defined in claim 4, further comprising means for mounting said envelope on the body of said vehicle in a vertical plane perpendicular to the direction of movement of said vehicle.
Claim 7
Dependent Claim
13 words
The system defined in claim 3, further comprising housing means enclosing said envelope.
Claim 8
Dependent Claim
66 words
The system defined in claim 6 wherein said housing means includes a pair of mirror-symmetrical housing portions together forming a box of rectangular configuration, each of said housing portions being formed with a pair of ribs having registering cutouts receiving the respective arms, with a pedestal between said ribs for supporting saiD bight portion of said envelope, and with means for securing said housing portions together.
