Claims

1. A CENTRAL BRANCH-OFF FACILITY FOR PNEUMATIC TUBE SYSTEMS FOR RECEIVING CARRIERS FROM DISPATCHING TUBES HAVING THE EXIT PORTS OF SAID TUBES DISTRIBUTED IN TWO DIMENSIONS AND FOR SELECTIVELY FEEDING SAID CARRIERS TO RECEIVING TUBES HAVING THEIR INPUT PORTS ALSO DISTRIBUTED IN TWO DIMENSIONS, COMPRISING:

A FIRST MEANS FOR RECEIVING SAID CARRIERS FROM SAID DISPATCHING TUBES AND SELECTIVELY DISTRIBUTING THEM AMONG OUTPUT LOCATIONS ARRAYED ALONG A LINE ORIENTED IN A FIRST DIRECTION, SAID FIRST MEANS HAVING THE GENERAL SHAPE OF A TRUNCATED PYRAMID AND BEING PIVOTED ABOUT AN AXIS SUBSTANTIALLY NORMAL TO SAID LINE;

A SECOND MEANS COOPERATING WITH SAID FIRST MEANS AND HAVING A PLURALITY OF INPUT POINTS CORRESPONDING TO SAID RESPECTIVE OUTPUT LOCATIONS OF SAID FIRST MEANS, SAID SECOND MEANS BEING ADAPTED FOR RECEIVING AND REDIRECTING SAID CARRIERS TO AN OUTPUT POINT CHOSEN FROM A PLURALITY OF OUTPUT POINTS ARRAYED ALONG A LINE ORIENTED IN A SECOND DIRECTION WHICH IS NORMAL TO SAID FIRST DIRECTION, TO DISTRIBUTE SAID CARRIERS TO OUTPUT POINTS ALONG SAID LINE IN SAID SECOND DIRECTION;

AND OUTPUT MEANS COOPERATING WITH SAID SECOND MEANS AND COMPRISING SAID RECEIVING TUBES, INCLUDING THE RECEIVING TUBE TO WHICH THE CARRIER IS IN EACH CASE TO BE DELIVERED.
