Abstract
A rotary feeder mechanism is provided for a stringer notcher wherein the feeder includes opposing pairs of pusher arms with one pusher arm of each pair being located on opposing sides of a magazine holding a vertically stacked supply of stringers to uniformly move the lowermost stringer onto a work table. The opposing pusher arms are eccentrically mounted on opposite sides of a rotary drive shaft. A control link is connected to each pusher arm to maintain the orientation of the distal ends of the pusher arms in a selected orientation during rotational movement. As one pusher arm moves a stringer onto the work table, the next vertically stacked stringer rests on the top surface of the stringer to be eased onto the bottom of the magazine as the pusher arm retracts below the level of the work table for the opposing pusher arm to then engage the next stringer.
