  • Patent number: 4311332
    Abstract: A shellfish rake in which a plurality of tines are laterally spaced from each other so as to form a basket having a generally open front face adapted to be closed by a spring actuated cover. The rear wall of the basket includes a guide adapted to receive an elongated pole which serves to actuate; that is, to dredge, the basket across the floor or shellfish bed of the ocean, river, etc. A line is attached to the basket such that the basket may be brought to the surface of the water while using the elongated pole as a guide rather than lifting the pole and attached basket as is conventionally done. An additional feature of the invention includes a frame supported by the boat of the user which includes a pivotally attached upright member in turn adapted to fixedly engage the pole such that back and forth pivotal movement of such member actuates the pole and thus drags the basket across the surface of the bed in a more efficient manner.
