  • Captive carrier for a transport tube system
    Patent number: 5368417
    Abstract: A captive carrier for a heavy payload system having end caps rigidly connected thereto. Each end cap has a sliding cover mounted in an outer most surface thereof, Restraining means on the cover restrain the cover from motion in response to the captive carrier tilting outwardly toward the user thereby opening the top of the carrier. The end caps and covers have a curved profile that corresponds to the curvature of the pivoting motion of the top of the carrier, The carrier further includes a wear strip mounted on one side which is directed vertically downward when the carrier is moving in a horizontal direction.
