Abstract

530,593. Drilling ; drills. ROE & CO., Ltd., A. V., and TAYLOR, R. F. June 28, 1939, No. 18792. [Class 83 (iii)] Twist drills, particularly those in portable power-spindled drills are supported against deflection and breakage by a telescopic sleeve c, d, the sleeve c being a sliding fit for the drill as also a collar f. A resilient washer or spring ring h prevents the device from sliding off the drill and ensures rotation with it. A compression spring between the two sleeves reduces shock when the drill breaks through. The end of the sleeve may be coned at i to engage a corresponding surface on a jig j.
