Abstract
Abstract An electric line connects a battery with the lights of a motor vehicle and includes a normally closed switch, between which and the battery there is a manually operable switch. Electrically operated means are provided for opening the normally closed switch and connecting the lights to the battery directly. Connected with said means is a normally open switch operated by a photoelectric cell. A clock-actuated switch connects the battery with said means from dusk to dawn and with the normally open switch and the cell from dawn to dusk. While the cell is connected with the battery, it closes the normally open switch whenever the cell fails to receive enough illumination.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
An electrical system for the lights of a motor vehicle, comprising a battery, an electric line connecting the battery with the lights, a normally closed switch in said line, a manual switch in said line between the battery and said normally closed switch, electrically operated means for opening the normally closed switch and connecting the lights to the battery even though said manual switch is open, a normally open switch connected with said means, a photoelectric cell, a clock-actuated switch having a contact connecting the battery with said electrically operated means from substantially dusk to dawn and having another contact for connecting the battery with said normally open switch and cell from substantially dawn to dusk, and electrically operated means controlled by said cell for closing said normally open switch whenever the cell fails to receive a predetermined amount of illumination while it is connected with the battery.
Claim 2
Dependent Claim
148 words
An electrical system for the lights of a motor vehicle, comprising a battery, an electric line connecting the battery with the lights, a normally closed switch in said line, a manual switch in said line between the battery and said normally closed switch, electrically operated means for opening the normally closed switch and connecting the lights to the battery even though said manual switch is open, a normally open switch connected with said means, a photoelectric cell, a clock-actuated switch having a contact connecting the battery with said electrically operated means from substantially dusk to dawn and having another contact for connecting the battery with said normally open switch and cell from substantially dawn to dusk, and electrically operated means controlled by said cell for closing said normally open switch whenever the cell fails to receive a predetermined amount of illumination while it is connected with the battery.
Claim 3
Dependent Claim
30 words
An electrical system according to claim 1, including a manually operable switch for disconnecting said clock switch from the battery and which serves as the ignition switch for the vehicle.
Claim 4
Dependent Claim
90 words
An electrical system according to claim 1, in which said normally open switch and last-mentioned electrically operated means form a relay operated by said cell, said normally closed switch has a movable contact, and said first-mentioned electrically operated means include a fixed contact electrically connected with the battery, and a solenoid coil connected with the clock switch for moving said movable contact into engagement with said fixed contact, said system including a manually operable switch for disconnecting said clock switch from the battery whenever the vehicle ignition is turned off.
Claim 5
Dependent Claim
52 words
An electrical system according to claim 1, in which said normally closed switch has a movable contact, and said first-mentioned electrically operated means include a fixed contact electrically connected with the battery, and a solenoid coil connnected with the clock switch for moving said movable contact into engagement with said fixed contact.
Claim 6
Dependent Claim
23 words
An electrical system according to claim 1, in which said normally open switch and last-mentioned means form a relay operated by said cell.
Claim 7
Dependent Claim
27 words
An electrical system according to claim 1, including manually operable means for turning off the lights while the battery is connected with said first-mentioned electrically operated means.
Claim 8
Dependent Claim
83 words
An electric circuit according to claim 6, in which said manually operable means include a second normally closed switch in said line between said first-mentioned normally closed switch and the lights, electrically operated means for opening said second switch, and a manually operable normally open switch connecting said last-mentioned electrically operated means with said first-mentioned clock contact, whereby if said last-mentioned switch is closed manually between dusk and dawn and said second normally closed switch will be opened to turn off the lights.
Claim 9
Dependent Claim
34 words
An electrical system according to claim 7, in which said second normally closed switch and said means for opening it form a relay that is operated by closing said manually operable normally open switch.
