Abstract

An automatic closing spout for a combine grain auger which opens when there is grain passing through the auger comprising a pivotally mounted collecting bucket attached adjacent the discharge opening of the auger with counterweighted arms extending outwardly from the collecting bucket to hold the bucket in a closed position, but insufficient when the bucket is full of grain from dumping and allowing grain to discharge from the auger housing and including a secondary closing means in the form of a permanent magnet which holds the collecting bucket in its closed position to prevent premature discharge therefrom.
