ABSTRACT:
A feeder-air lock provides a pair of slide gates, with the support for the slide gates and the mechanism for driving the slide gates located outside of the material passage, so as to provide a smooth, downwardly-sloping wall for directing the material downwardly without trapping or jamming material and so that the feeder-air lock provides a reliable mechanism which requires little maintenance.
