ABSTRACT:
Apparatus for dispensing a comparatively fine, particulate material uniformly over a subjacent surface. The disclosed apparatus comprises a hopper assembly adopted to be mounted over the surface. The hopper assembly has sides defining a downwardly open, horizontally extending, elongated discharge mouth. An elongated, cylindrical drum member extends the length of the mouth. Wiper blades extend from the sides of the hopper assembly into engagement with the drum. A multiplicity, of narrow, shallow grooves extend circumferentially about the drum. The grooves are sized such that the particulate material will not normally flow therethrough except upon rotation of the drum. For this reason structure is provided for selectively rotating the drum in at least a first direction to cause discharge of the particulate material. To produce uniform dispersion of the particulate material, divider-deflector members are associated with each groove.
