ABSTRACT:
The signal device, secured to the door of a rural mailbox, shows that mail has been received. The device operates by opening a shutter to display the message, "MAIL," when the mail carrier opens the mailbox door. It operates by gravity and latches magnetically. The shutter opens as a venetian blind when the weighted screen falls forward. The signal device is reset by pushing the reset tab. The device returns to the closed position by gravity. In the closed position the message, "NO MAIL," printed on the shutter, is displayed. Moving parts are contained in a weather-proof box with a transparent window. The messages, "MAIL," or "NO MAIL" are visible through the transparent window.
