Abstract
A chip sampling device comprising a sampling probe including an outer rotatable tube having an inner tube positioned therein. The upper end of the inner tube is in communication with a source of vacuum so that chips will be drawn into the lower end of the inner tube. The lower end of the inner tube is provided with serrations provided at the lower end thereof while the lower end of the outer tube is provided with serrations and inwardly extending fingers. The rotation of the outer tube and the action of the various serrations and fingers prevents the chips from plugging the lower end of the outer tube or from plugging the lower end of the inner tube.
