The carriage includes first, second and third pivotal support members. The first support member pivots upwardly and forwardly from said support surface and carries the tray thereon. The second support member is also pivotal upwardly and forwardly and is positioned adjacent to and forward of the first support member. The second member receives the tray from the first support member. The third support member is mounted to the second support member forward thereof and is adapted to receive the mail pieces thereon. The third support member pivots forwardly to receive the mail pieces and subsequently, pivots rearwardly to reorient the mail in a generally vertical orientation.
