ABSTRACT:
A mail box signal device article is adapted for ready installation to a street mail box. The article comprises a housing for holding the components of the device, with the housing itself attached to the mail box. Mounted on the housing is a hub assembly comprised of an axle which extends through a side wall of the housing, a first disc rotatably mounted on the axle within the housing and a second disc rotatably mounted on the axle outside of the housing. The two discs rotate together. An arm extends from the first disc and has a lateral pin extending at a right angle from one extremity. A slide link with an elongated slot is slidably connected with the lateral pin of the arm. A bracket pivotably attached to one extremity of the slide link is intended for permanent mounting to a door of the mail box. A signal is fixedly attached to the second disc of the hub assembly. The signal is moved to a vertical position when the door is opened and remains there until disengaged by the owner.
