  • Patent number: 5247282
    Abstract: A delivery signal and appliance control system generates audible or visual signal within a dwelling to indicate that a delivery, such as a newspaper or piece of mail has been deposited in a remote delivery container, such as a mailbox, and also controls current through electrical wall receptacles inside the dwelling to operate appliances responsive to the delivery. The system has a delivery notification switch at the remote delivery container which is connected to a control box in the dwelling. The control box is connected to dedicated electrical wall receptacles into which electrical appliances may be plugged. The control box has a DC circuit activated by the delivery notification switch upon receipt of an article being deposited in the delivery container to generate an audible or visual signal and to control an AC circuit which allows electrical current through the dedicated electrical receptacles to provide electrical power to electrical appliances plugged into the receptacles.
