Absract
My invention covers an improved jaw and cradle and is shown in a familiar form of lathe or drill chuck. Its purpose is to facilitate the operation of such chuck by providing a means for positioning the several dogs on their mounts at an exactly equal distance from the center of the chuck so that by the use of the scroll ring they may be simultaneously moved toward or from the center, always being maintained severally at an equal distance from the center. |
