ABSTRACT:
A sorting apparatus and method for sorting mail matter. The apparatus comprises a cabinet including a series of rows of pigeonholes, each pigeonhole having in registry therewith indicia provided on a shiftable support setting forth destination information, as well as related code information, for the mail matter to be placed therein. One indicia-bearing support is provided for each row of pigeonholes, and the indicia are arranged thereon in sets. The full complement of indicia-bearing supports are simultaneously shiftable between multiple given positions corresponding to the number of sets of indicia.
The method is carried out by first positioning the full complement of supports to display a primary set of indicia. The destination of the uncoded mail matter to be sorted is matched with the indicia of the primary set and deposited in the appropriate pigeonhole. The accumulated mail matter is removed from the pigeonholes, and the full complement of supports is shifted to display a selected one of the remaining sets of indicia, each set of which bears a species-genus relationship to one of the indicia of the primary set. Thereafter, the indicia of the primary set generic to the selected secondary set of indicia is identified. The indicia on the mail matter removed from the pigeonhole associated with the identified primary indicia is then matched with the corresponding indicia of the displayed secondary set and deposited in the appropriate pigeonhole. The mail matter may be encoded during sorting.
