  • Device for taking bottom soil samples from deep water basins
    Patent number: 4116069
    Abstract: The device comprises two independently operating systems which are separated from each other in kinematical and actuating respects, viz, a system for closing the jaws of the sample-taking grab and a system for dropping the ballast weights. Said system for dropping the ballast weights is based on the principle of unstable fixing of the weights, the weights being detached from the sampling device after the leader rod strikes the bottom of the basin. Various embodiments of the grab-closing system incorporate, for example, a pulley block and cable mechanism intended first to close the grab jaws, and then to lift out the entire apparatus by taking up the free length of the cable.
