Abstract

168,299. R÷hm-Ges. Aug. 24, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Chucks.-The jaw-carrier 9 of a drill-chuck is mounted in a coned-sleeve 5 bv means of the flange 9<a>, and is thus adapted to be screw-adjusted in the holder 1, thereby closing the three bevel-jaws 7 against the action of a spring ring 15. Each jaw is fitted with a pin 12 which engages radial guides formed between a three-part ring 14 and a spring ring 1<a> on the end of the holder. A headed spindle 17 is centred in the jaw-carrier and is adapted to abut against the end of the drill shank.
