Abstract

1,172,774. Portable electric drills. ARCOY PRODUCTS Ltd. 25 July, 1968 [25 July, 1967; 31 Jan., 1968], Nos. 33997/67 and 4918/68. Heading B3C. [Also in Division F2] A drive spindle between a gear (4) and chuck (2) of an electric drill comprises two spindle sections 7, 13 coaxially connected for torque transmission by an electric insulating block 3 which extends along one spindle section 7 to form an insulated bearing surface 19. A disc 8 on the end of the spindle section 7 has axial projections 9 which engage with play between radial projections 14 on the spindle section 13. The block 3 is moulded round the spindle ends to insulate the spindle sections from each other. The block 3 may be nylon as polyester resin. When a bearing surrounds the surface 19 a flange (23) may be spin-welded to the end 21 of the extension of the block 3.
