  • Patent number: 4821818
    Abstract: The present invention comprises first and second auger sections having upper and lower ends. The lower end of the first auger section is detachably secured to the upper end of the second auger section. The lower end of the first auger section includes a collar having axially extending indentations and projecting therein. The upper end of the second auger section includes a similar collar having axially extending projections and indentations therein. The two collars are matingly interlocked to prevent rotation of the augers sections with respect to one another. A detachable coupler surrounds the interlocked first and second collar means and holds them against axial movement away from one another. A seal causes the two ends to be sealed with respect to one another so that fluid cannot enter the internal bore of the tube sections.
