Abstract
An apparatus for intermittently pushing a plurality of aligned carts along a predetermined path. The apparatus includes a pair of oscillating pusher bars having a plurality of aligned lugs thereon, which engage a portion of the undersurface of the carts and push them forward as the bars move in a forward direction. As the pusher bars move in the opposite direction, the lugs disengage from the cart, so as to permit the cart to remain stationary.
