Abstract

246,407. Metzger, E. Sept. 24, 1925. Chucks; yielding-drive attachments.-A drill chuck with a yielding drive has the spring pressure between the clutch members automatically varied according to the size of drill in use. A shank carries a casing a containing a spring b and au axially movable coned washer c. The latter has grooves f on its underside co-operating with tho tapered ends of pins g secured to screw operated jaws h. A member i carrying the jaws is secured to a bush s rotatable relatively to circular keys A held by the casing a. At overload the pins g ride out of the grooves f and allow the casing a to turn relatively to the drill, greater torque being required for large drills owing to greater initial compression of the spring b.
