ABSTRACT:
A mail box according to the teachings of the present invention is shown as including a rectangular box with a receiver's door side-hinged and locked by a combination lock, to and within the frame of a bottom-hinged delivery door. The bottom-hinged delivery door is locked at the top and side and opened only by a delivery person with a special release tool which is thrust into a side chamber of the unit and forces a latch gate sideways which draws a latch from the side of the door and simultaneously transmits the force of the entrance, through tangential movement of a release rod, to an L-shaped connector to a release cable which extends through rollers to the top latch of the delivery door. Spring action automatically closes both latches. Supplemental brace hinges are included to enable the delivery door to be held ridgidly horizontal when open. Automatic means to indicate a package has been delivered is provided by a signal finger out the front of the side chamber which is activated by connecting means to the release rod and is released by hand. Other hand operated signal means are provided to indicate, by an arm extending out the front or one extending out the top that there is a package or letter in the box. A letter signal wheel in the receiver's door, activated automatically by the letter slot, indicates a letter delivery by showing a certain color.
