Abstract
An improved bucket wheel for a dredge having a flush jet arrangement for clearing the buckets of sticky material, an improved divider arrangement for preventing entrance of oversized objects into the buckets and means for expelling air trapped in buckets when the wheel is operating only partially submerged. The flush jet operates through the open bottom of each bucket to expel matter from the buckets substantially radially outwardly. The air expeller is an escape path, such as a chordal flat, between the hub and rim of the wheel in the region where air might be trapped by the buckets. The divider is a plate securely attached to each bucket of adjacent pairs of buckets and lying in the mid-plane of the wheel.
