摘要： A core catcher for a core sampler has a hollow, semi-ellipsoidal body adapted to be fitted into a sample tube and being open at one end to permit material to be sampled to pass into the tube through the body. The body is slit axially from its other end to form a plurality of resilient, flexible, longitudinally and transversely arched fingers which may be flexed outwardly or away from one another as material to be sampled passes through the body. The fingers have convex, free ends which terminate short of one another to minimize scoring of the sample. The fingers are of such length as to enable their free ends to be deflected inwardly of the body into overlapping relation to form a support for material in the tube.

摘要： A water sampler having a tubular body open at both ends and through which extends a connecting rod fixed at one end to a closure for the lower end of the body and carrying an enlargement at its other end for engagement with and disengagement from a latching clasp supported on a closure for the upper end of the body. The latching clasp comprises a pair of segment-shaped plates between which the enlargement is adapted to be retained, each of the plates having an upstanding motion transmitting member operable to move the plates apart and effect release of the enlargement. The clasp plates preferably are biased to move toward one another by two springs which straddle the connecting rod.

摘要： A dredge especially adapted for taking samples from the bottom of a body of water comprises a hollow body open at its top and bottom, but provided at both its top and its bottom with closures movable between open and closed positions and biased to their closed positions. The top and bottom closures are equipped with means for latching the closures in their open positions. A latch release mechanism is provided for effecting release of the closure latch members so as to enable the closures to move from their open positions to their closed positions.
