A new and improved newspaper delivery box signalling apparatus includes a housing assembly for receiving and containing a delivered newspaper. The housing assembly includes a first opening for receiving the newspaper, and includes a second opening for permitting signalling of newspaper delivery. A delivery signal assembly is supported by the housing assembly and signals delivery of a newspaper. The delivery signal assembly includes a signal flag, a counterweight, and a lever/fulcrum assembly supporting the signal flag and the counterweight. When no newspaper is present in the housing assembly, the counterweight, through the lever/fulcrum assembly, positions the signal flag is the nondelivery position. However, when a newspaper has been delivered, the weight of the newspaper, through the lever/fulcrum assembly, overcomes the counterweight and moves the signal flag to the delivered position. In a first embodiment of the invention, the second opening of the housing assembly is located on a bottom wall of the housing assembly and is large enough permit the signal flag to move back and forth from a nondelivery mode to a delivery mode through the second opening in the bottom wall. In a second embodiment of the invention, the second opening of the housing assembly is located on a side wall of the housing assembly. In this embodiment, the lever/fulcrum assembly includes a control shaft which passes through the second opening and moves the signal flag, which is supported by the control shaft, back and forth from a nondelivery mode to a delivery mode.
