Abstract
An apparatus for tipping a bucket carried by a conveyor chain around a circuit to empty the contents thereof at a predetermined location. The apparatus is characterized by providing a dwell time to the bucket in its inverted position as the bucket is rotated 360 degrees around a fixed pivot degrees to permit complete emptying of the buckets. The apparatus comprises a sprocket mounted concentric with the pivot about which the bucket rotates and fixed for rotation with the bucket. The sprocket has a plurality of radially outwardly-extending uniformly spaced-apart projections and at least one space on the sprocket defined by the absence of a projection. An elongate rack is positioned adjacent the chain at the bucket tipping position and has sprocket engaging portions thereon positioned in engaging alignment with the projections of the sprocket as the bucket passes, thereby to arrest rotation of the bucket while the bucket is in its inverted position to permit the contents to empty entirely.
