Abstract

The finger follower employs two independent lost motion arms and a rod which moves longitudinally to lock both arms. The rod is transversely mounted in the follower. In order to avoid premature locking, a clip is employed with tabs that interact with end surfaces of the arms so as to prevent premature movement of the rod from an unlocked position to a locked position.
