Abstract

258,930. Ritscher, W. June 27, 1925. Wireless tuning-apparatus, adjustment devices for. - In coarse and fine adjustment devices for radio apparatus comprising a gear wheel directly mounted on and frictionally engaging with the movable member and operated by a pinion through spring- biassed transmission wheels, the teeth of the pinion and wheels are of such size and form as to prevent play in both directions of rotation. As shown, the teeth of . the gear i, h, l, y are cut obliquely, the wheels l, y being mounted on spring urged arms m, m<1>. The lower bearing is formed in a bracket x, units q, r being provided for locating the concentric operating-shafts a, f.
