ABSTRACT:
A dredge with an elongated boom mounted to extend at an angle from the vertical has at a lower free end of the boom a pump inlet and disc-cutters mounted on the boom. The disc-cutters are rotated on axes of rotation lying at an acute angle to a continuation of the long axis of the boom beyond its free end whereby the disc cutters are tilted toward the inlet mouth at their near sides. The axes of rotation of the discs are also at an angle from the perpendicular with respect to the surface of liquid on which the dredge floats greater than that of the boom so that the axes of rotation of the discs are more nearly perpendicular to the vertical than is the axis of the boom.
