Abstract

1,048,179. Portable drills. SHINKO ELECTRIC CO. Ltd. Sept. 14, 1965, No. 39286/65. Heading B3C. [Also in Divisions B4 and H2] A rotary-percussive drill comprises an electric rotary motor 3, 5 arranged to drive a shaft 2 and an electromagnet 15 having an armature 16 supported by an elastomer body 17 to allow vibration and having an impact part adapted to infringe upon the shaft when the electromagnet is excited. The electromagnet comprises a yoke 13 carrying a core 14 on which a coil 15 is wound and the armature is provided with an impact pole 20 adapted to strike the end of the shaft; a resilient portion may be secured to the end of the impact pole. In a modification, Fig. 3 (not shown), the armature 16 is connected by a disc 17<SP>1</SP> of elastomericmaterial to the casing of the drill.
