324,960. Proctor, A. Aug. 8, 1928. Rippling-apparatus.-Apparatus for rippling or de-seeding flax, hemp, &c. comprises a drum C, provided with bars F carrying pins or pegs f1 preferably bent backwards, and rotated within a casing B mounted on a wheeled frame. An adjustable concave grid G is mounted below the drum, through which the seeds and debris fall on to a perforated tray N, which is reciprocated by a crank. The seeds slide down the tray to a spout, n1. The material is fed to the drum through a pair of feed rollers J, K. These rollers and the feed table H are adjustable towards and from the, drum, so that they may be placed at such a distance that when the drum has completed its rippling action the root ends of the stalks will be freed from the feed rollers and no further beating action will take place on the straws. The straw passes out over a grid g1 and may be delivered by an associated elevator E to carts or to a stack. The feed rollers are spring pressed and may be plain or grooved, the pressuret being adjusted to break the seed pods or to leave them whole.
