Abstract

1393948 Portable electric drills ROBERT BOSCH GmbH 15 June 1972 [16 June 1971] 27964/72 Heading B3C [Also in Division F2] In a portable-electric-drill the gears 15 are actuated by a lever 8 having a strap 7 rotatably mounted in a bearing 4 in the split casing 33, of the drill, the strap being split and bared at one end 12 so as to mount a pin 13 eccentrically. Pin 13 is located in a groove 14 in the gears, and in order to adjust the gears, the lever is pivoted so that a lug 9 is located in a released one of two notches in the casing. Strap 7 is held in the bearing by a resilient collar 9<SP>1</SP>.
