ABSTRACT:
An arrangement for preventing clogging of particulate material flowing through a curved section in a tubular duct or chute employs an air manifold operatively associated with the duct or chute and having an elongated discharge orifice positioned to discharge a wall of pressurized air along the internal concave duct surface so as to create positive laminar air flow along the curved surface and prevent stagnation and clogging of the particulate material. In a preferred embodiment, mutually cooperating auxiliary air discharge openings in the manifold and duct effect laminar air flow over other internal surface areas of the duct within the curved section. The anti-clogging arrangement finds particular application in grass mowers and the like wherein clippings tend to clog within curved sections of chutes through which the clippings pass to a receptacle.
