Fluid intake openings for a suction dredger

Image Number 4 for United States Patent #4399622.

A dredging apparatus is afforded having the improvements of a wedge-shaped dredge foot housing both a fluid opening and a filter member, the intake opening being located on the underside of the dredge foot and the filter member being located above the fluid intake opening so as to be placed between the intake and the suction conduit, the taper of the wedge foot being toward its forward edge and its underside being substantially planar. Also afforded is providing the lower end of the dredge housing with a forwardly directed lever means comprising a lever member capable of being reciprocally moved in order to effect the levering of large objects, thus enabling the location of the intake opening below such objects.
