    Patent number: 4032003
    Abstract: A conveyor drive system employing a constant speed master drive and a slave drive of the hydrostatic, closed loop type in which there are no electrical or hydraulic feedback lines between the master and slave drive unit. The master drive moves the conveyor at a constant speed as load varies and the slave drive unit responds to changes in load on the conveyor to vary the speed of the drive to maintain a constant pull on the conveyor to insure that the slave drive shares its portion of the load with the master drive.
