Abstract
1452129 Percussive drills ROBERT BOSCH GmbH 26 Oct 1973 [28 Oct 1972] 49903/73 Addition to 1447867 Heading B4C [Also in Divisions B3 and F2] The electrically-operated hammer drill of the parent Specification is modified by having the intermediate shaft 11 together with its gearwheels 20, 21 for the two-speed rotary transmission and its gear-wheel 22 for the percussive mechanism of unitary construction. Other modifications include having the axes of all the gear-wheels in a single central plane, using a bearing block 17 screwed to the housing, and having a slip clutch, Fig. 4 (not shown) with thrust rings (77, 78) which yield apart by balls (36) or by rollers (86) Fig. 5 (not shown).
