ABSTRACT:
An improved outgoing mail signal device for use on rural mailboxes which are partially enclosed by decorative structures such as those composed of brick (or stone) and mortar. The device comprises a support bracket mounted to the door of the mailbox and a signal arm pivotably coupled to the bracket. In operation, the signal arm is rotated up to a stable, over-centered, raised position to indicate the presence of outgoing mail. Upon opening the door, the signal arm returns to the lowered position automatically under the action of gravity. The device has only two stable rest positions, fully raised and fully lowered, for unambiguous signaling. To a viewer located to the side of the mailbox, the signal arm is highly visible when in the raised position and hidden from view when in the lowered position.
