ABSTRACT:
Apparatus for controlling the operation of dump doors of a wagon or the like, permitting the operator to set a control lever selectively in a closed or open position, with the apparatus effecting the desired selective movement of the doors and returning the control lever to a "Hold" position upon completion of the desired movement. The apparatus includes a cam device responsive to the movement of the doors to the selected position for releasing the control lever and thereby terminating the driving of the doors to the selected position. The apparatus alternatively may provide a single full movement of the doors or a sequential movement, as desired.
