Abstract: A grain elevator system for an elevator which includes a crib means defining an elongated elevator enclosure with a delivery head disposed at the upper end thereof, an elevator disposed within the crib enclosure including a bucket elevator system having a foot pulley journaled for rotation on a foot shaft, a head pulley journaled for rotation on a head shaft, and a continuous belt means arranged therebetween and supporting a plurality of buckets therealong, the elevator including an integral head enclosure means having a grain discharge end and a throat receiving end along with means for supporting the head shaft. The system further includes throat means secured to the crib enclosure defining an enclosure for the bucket elevator system, the throat means being secured to the elongated sides of the crib enclosure and having a throat opening at the upper end thereof. The throat is slidably coupled to an opening formed in the throat receiving end of the elevator head enclosure means in order to accommodate relative motion between the throat means and the head enclosure means. An extension is formed on the upper end of the throat, the extension having an opening therein extending upwardly from the opening formed in the throat receiving end of the head enclosure means, this throat opening having laterally disposed guide means spanning an opening formed in the throat and arranged to accommodate telescoping motion relative to the head enclosure means. A collapsible baffle means is provided which extends across the opening formed in the extension, the baffle means comprising a plurality of elongated integral plates, each plate being linked to its next lower neighbor to form a closure over the opening in said throat extension, with each of the integral plates being adapted to fall freely from its next lower neighbor when free from the laterally disposed guide means.
