My invention has for its object to improve the construction of the jaws of lathe-dogs, bench-vises, etc., so that they may be able to hold the work, firmly, whether it be straight or tapering; and it consists in the combination of the semi-cylindrical self-adjusting pieces or jaws with the jaws of the dog or vise, as hereinafter more fully described.
