Abstract
A movable cable plow for dredging an underwater cable groove in a sea bed is disclosed wherein the plow is attached to a main body adapted to be pulled across the sea bed, such that it is adjustable vertically and angularly with respect to the main body. This allows the acurate control of the depth of the dredge groove. Also, a cable guide is pivotably attached to the plow, by way of a torsion spring hinge pin, so as to swing laterally with respect to the plow. This minimizes the lateral forces transmitted to the main body during the turning of the apparatus and, thereby, reduces the chances of the main body tipping over during the turning operation.
