Abstract
253,767. Hansen, A. C. V. July 16, 1925, [Convention date]. Wireless tuning-apparatus, adjustment devices for; inductances.-A coil holder for wireless apparatus of the kind wherein the coil is grasped by two arms comprises a forked member provided with resilient arms which follow closely the periphery of the coil and engage conductive strips lying on the circumference thereof, the coil itself being completely enclosed in an insulating casing. As shown, the holder is provided with forked contact arms 11 which engage the coil 2 along conductive strips 3. The coil is housed in an insulating casing 1 secured by a hollow bolt 5, and coil units not in use may be hung on pegs engaging these bolts. Fixed and movable coils 13, 17 may be mounted together in frictional engagement by a spring 14 located between them, the movable coil being pivoted on the bolt 15.
