Abstract
Abstract Apparatus for sorting, carrying and delivering mail or the like characterized by a plurality of sorting trays that can be inserted directly into existing or new sorting bins for sorting; carried; and stacked in a vehicle, such as a mail jeep, for delivery. The sorting trays have a sloping back side and two sloping ends for stacking the bottom of an upper tray inside of the top of a lower tray without the bottom of the upper tray resting on partitions in the lower one. The partitions are carried by the bottom so as to define mail slots therebetween. Label holders are provided along the front bottom of each tray and include a plurality of street and address slots that are aligned with the mail slots and are inclined at an angle with respect to the bottom so as to be visible to a mail carrier. The partitions have respective recesses for gripping the mail for easy removal. The sorting trays have interlocks and retainers to prevent their sliding in relationship to each other as the carrying vehicle is stopped and started. Also disclosed are specific and preferred embodiments.
