ABSTRACT:
A gravity powered part transfer system in which parts are suspended on a rotating member from a declining track or rail. The rotating member is associated with a viscous fluid in a manner which permits the active fluid to be altered in thickness in response to increase or decrease of weight. The greater the weight, the less the thickness of the fluid acting on the rotating member and the greater the retardation torque.
