Number: 172/296
Name: Earth working > Series of like elements sequentially operated by power cycle > Shaft with spirally arranged projections
Description: Apparatus in which the power-driven actuating means comprises a rotatable shaft having radially projecting portions arranged at longitudinally and circumferentially spaced points on said shaft, and means operatively connected to the like elements of the apparatus for sequentially moving them, said means being located in the paths of said radially projecting portions so that the lost motion due to the circumferential spacing of the portions causes sequential motion of said parts.
