  • Soil testing assemblies
    Patent number: 5931237
    Abstract: An apparatus for securing a soil testing device and other attachments necessary for soil testing near the bottom of a borehole uses a pair of clamps with gripping teeth that interlock with similar gripping teeth in the internal wall of the auger. The lateral movements of the clamps toward the auger are controlled so that the soil testing device is maintained in a proper orientation with respect to the soil sample and to avoid uncontrolled engagements of the clamps with the auger.
