Chip spreader

In a spreader for granular material, means for holding a mass of flowable granular material including a stationary bottom wall for supporting said mass, a lateral discharge nozzle having its leading end receiving material from a lower part of said mass and conducting the same to an outlet, an unobstructed discharge grille crosswise to the direction of flow between said inlet and outlet, said grille having its leading side in contact with a lower part of said mass and subject to the gravity head from the part of said mass above said lower part, said grille having vertically spaced bars oriented crosswise of the direction of flow through the grille, the width of the bars being such that the material will not flow through the grille under static conditions but will flow through the grille when the material is subjected to vibration by vibration means.
