ABSTRACT:
A device for feeding sheets of paper to be interleaved with a stack of meat patties includes a vertical push rod within a tube which is slidable in a hole in one end of a feed arm. The feed arm is connected at the other end to a vertically oscillating shaft which moves up and down in conjunction with a meat patty ejection arm. The upper surface of the feed arm also supports a pivoting lock plate having one end mounted on a vertical post. The other end of the lock plate includes a hole accommodating the slidable tube. The lower end of the push rod includes a pressure foot which rests on top of a stack of paper sheets. A spring is positioned around the push rod between the pressure foot and the lower end of the slidable tube. When the oscillating shaft moves down, the lock plate pivots to an angular position which causes the slidable tube to be gripped within the hole in the lock plate. The tube is thus moved downward on the push rod to compress the spring which applies pressure against the foot and the stack of papers. This provides the desired force against a moving conveyor belt below the paper stack to permit pulling the bottom sheet from the stack to feed the paper below the patty forming mechanism to properly interleave the paper with the patties.
