Abstract

252,961. Newey, J. G., and Jerred, C. B. Oct. 5, 1925. Wireless tuning-apparatus, adjustment devices for.-In gearing of the type in which a driving-wheel meshes with two or more toothed segments or wheels which are rotated simultaneously for adjusting wireless instruments, a spring engages each driven member with opposite turning moment for preventing backlash in the gearing. The springs d are coiled around the gear spindles b, one end of each spring engaging the segment or wheel at a point g remote from the spindle, the other end being anchored in a fixed frame part e.
