Abstract
A machine for applying a clip to a tie at a side of a rail and detecting when the clip has been fully seated comprising, a head positionable at a predetermined location relative to the tie and rail, a pair of arms pivotally mounted on the head for rotation in a plane which extends parallel to the rail, and power structure for simultaneously pivoting both of the arms between a raised retracted position and a lowered position. Movement between the retracted and lowered positions causes a clip-engaging member on one arm of the pair to engage and advance the clip to a fully-seated position. The second arm of the pair detects when the clip has reached the fully seated position and stops further movement of the clip-engaging member.
