ABSTRACT:
A carriage of the tiltable plate kind for a sorting apparatus has a carrying structure having idle wheels for running in a feed direction along rails on one side of the carrying structure and a pair of spaced uprights projecting from the opposite side of the carrying structure. A frame is hingedly linked to the one side of the carrying structure, the frame having pairs of wheels for engaging opposite sides of a fixed rail. A motor drives at least one wheel of the pairs of wheels of the frame for self-driving the carrying structure. A plate is hinged to end portions of the uprights for rotation about an axis substantially parallel to the feed direction of the carrying structure. A rotatable threaded shaft is between the uprights in the feed direction of the carrying structure. A guide is along the carrying structure in the feed direction thereof and a cursor is on the guide and engaging the threaded shaft for movement along the guide in the feed direction of the carrying structure by rotation of the threaded shaft. A pair of cams is on the plate on opposite sides of the threaded shaft transversely of the feed direction for engaging the cursor, the cams having symmetrically equal contours for tilting the plate in either direction upon rotation of the threaded shaft and movement of the cursor.
