Abstract
Intercept arms of a stacker are coupled to the drive chains by connecting links pivotally connected at one end directly to one of the drive chain links so that the pivot point of the connecting link is coincident with the pitch centerline of the drive chain resulting from the fact that the connecting link forms an integral part of the drive chain, directly replacing one of the drive chain rollers. The connecting link design provides a mechanical advantage of five to one and is pivotally mounted and angled so that the connecting link is free to pivot about the chain to avoid interference as the intercept arm moves about the sprocket, providing greater stability to the intercept arm while simultaneously increasing the mechanical advantage thereby significantly reducing power losses.
