Description: |
"The small screw on the end of the auger which guides and draws it into the wood is not a continuation of the large screw or twist of the auger, but is independent of and separate from it by a bar marked a, about the size of the small screw, more or less. In consequence of this bar, upon which no screw is cut, the cutters or lips of the auger are left free to enter the wood, boring it more rapidly and much easier than when the screw and the large twist of the auger are connected. I call it the 'Independent Screw-Auger'." |
