Abstract

Apparatus for sorting flat mail bearing postage indicia adjacent one corner thereof. Pieces bearing postage indicia adjacent their leading edges are selectively sent to first or second transfer stations according to whether the indicia is adjacent the top or bottom edge. The pieces are caused to fall from the first or second transfer stations onto a common conveyor in such a fashion that all pieces on the conveyor are similarly positioned. Those pieces wherein the postage indicia are disposed adjacent their trailing edges are directed to third and fourth stations. The third and fourth stations operate similarly to the first and second stations to position the pieces uniformly on a second conveyor. Each of the first and second conveyors supplies a first and second loading station. At these stations postal trays are automatically filled with mail from the respective conveyors and thereafter the filled trays are deposited in uniform relationship upon a common conveyor.
