Abstract

1471604 Hammer drill chucks UPAT-MAX LANGENSIEPEN KG 28 June 1974 [28 June 1973 24 April 1974] 28865/74 Heading B4C A tool 13 of hexagonal section is held in a chuck of a hammer drill or the like by means of a pin 20 which is held in a bore at right angles to the tool axis by means of a spring 60. The pin 20 is located in a recess 15 of the tool shank which recess allows small axial movement of the tool. Fig. 6 shows the pin 20 held in place by the two end portions 51, 52 of spring 60. To remove the pin and release the tool a screwdriver 18 or the like is pushed through a hole 54 to move the pin 20 to the position shown in Fig. 7 where it is retained by the ends of spring 60. To remove pin 20 wholly it is pressed downwardly when in the position shown in Fig. 7. Several forms of reinforced spring ends are described.
