Abstract
An ice auger extractor for retrieving augers or similar devices from a bore ole includes a cylindrical housing and a spring-biased locking cam positioned in a vertically extending recess. The recess is substantially L-shaped and extends in a portion of periphery of the housing. The cam includes a serrated edge which secures the auger rod within the bore of the housing before its retrieval. A bore adapter may be connected with the housing and includes a substantially L-shaped snagging hook for centering the auger rod in the situation where the free end of the auger rod is embedded in the wall of bore hole. The housing and the bore adapter both include frusto-conical surfaces for guiding the auger rod into the housing.
