Abstract
A control device is provided for controlling the speed of a vehicle used in a conveyor system wherein the vehicle moves along a track. The control device has a generally straight section between a first angled section having a cam surface for deceleration and a second angled section having a cam surface for acceleration in a controlled manner. The control member is supported for movement between operative and inoperative positions. A motor is provided for moving the control member from an inoperative position to an operative position. The control member is held in its operative position by a cam follower on the vehicle. When the cam follower loses contact with the control member, the control member moves to its inoperative position by gravity.
