Abstract
A tow line accumulator is provided having at least one conveyor chain track or channel which is stationary and associated with first and second movable control members. The control members cause a tow pin on a driverless tow vehicle to lose contact with a pusher dog on the conveyor chain whereby the vehicle will come to a stop at the accumulator.
