Automatic Cartridge Tape Library Exchange Port

       Disclosed is a device which permits the exchange of
cartridges between two adjacently installed automatic cartridge tape
libraries.

      When two independent automatic cartridge tape libraries are
installed adjacent to each other and it is desired to pass cartridges
between them, some means must be provided to rotate the cartridge
such that it has the correct orientation for the receiving accessor.

      This article describes a device which uses gravity to rotate a
cartridge 180 degrees about a vertical axis such that it is correctly
oriented for the receiving accessor.

      The device is a vertical sleeve with two internal surfaces
defined by a straight helix (see Fig. 1).  The other two internal
surfaces may be either the internal surface of a hollow cylinder or
by straight helical surfaces at right angles to the other two.  The
internal dimensions of the sleeve are sufficiently larger than the
external dimensions of the cartridge to allow sliding passage of the
cartridge.

      The sending accessor inserts a cartridge into an opening at the
top of the sleeve and releases it.  The "rear" surface of the sleeve
provides a back-stop for the cartridge.

      Gravity causes the cartridge to move down.  Contact between one
face of the cartridge and one of the helical surfaces causes the
cartridge to rotate about a vertical axis.  The cartridge continues
to drop and rotate until it has ro...
