Abstract
An apparatus for tipping about a horizontal axis a bucket carried by a conveyor chain around a circuit to fill the bucket with contents at a predetermined location and empty the contents thereof at a predetermined location. The apparatus comprises a bucket pulley mounted for rotation with the bucket on one end thereof concentric with the horizontal axis about which the bucket is tipped, and an elongate bucket pulley-engaging device positioned adjacent said chain at a predetermined point on the circuit where the contents of the bucket are to be emptied. The bucket pulley-engaging device has a length at least as long as the circumference of the bucket pulley and frictionally engagable with the circumference of the bucket pulley to rotate the bucket pulley and thereby rotate and invert the bucket mounted thereon as the chain moves the bucket along the length of the bucket pulley-engaging device.
