bag or other suitable container 24 has been attached with its open mouth below chute 20 the bottom of the bag or container 24 rests on trough 22 wall 16 is moved to the right fig1 along tracks 34 and 36 to close housing 10 a suitable closing mechanism not shown may be used to lock wall 16 in place the open mouth of chute 20 with the bag attached now lies inwardly below the upper portion of drum 12 the open mouth of chute 20 is such that it is slightly greater than the length of slot 80 so that when slot 80 is rotated to appear above chute 20 slot 80 overlies the open mouth of chute 20 and all of the granular material which falls through slot 80 falls through chute 20 into bag 24 the prime mover is energized and through the drive mechanism rotates drum 12 to bring slot 80 to various positions within housing 10 when slot 80 is at its uppermost position it lies directly below hopper 40 and allows granular material to flow from hopper 40 through chute 20 into bag 24 when slot 80 is out of alignment with hopper 40 none of the granular material falls into bag 24 thus it is seen that only a selected quantity of the feed stream through hopper 40 will fall into bag 24 the remainder of the granular material falling through hopper 40 will fall onto and around the periphery of drum 12 and fall through the bottom wall 90 which is a mesh or grille this material.
