Abstract

28,406. O'Rorke, G. M. Dec. 9. Bore-hole apparatus.-An extractor for broken drills comprises a rod a screw-threaded at its outer end and formed with jaws b at its inner end, a sleeve g which is forced over the jaws by a nut j to grip the drill d, and a tripod m cooperating with a sleeve p and nut r to withdraw the tool and drill from the hole. The sleeve g has a hole k so that it may be held against rotation, and its outer end is screw-threaded so that when a drill is immovable the sleeve may be drawn back from the jaws b and the tool removed. Extension-pieces may be provided for the rod a and sleeve g.
