Abstract

411,713. Adjusting wireless apparatus. McGLOIN, J. P., 7, Castlewood Park, Rathmines, Dublin. Aug. 16, 1933, No. 22868. [Class 37.] A control device for tuning wireless receivers comprises a spindle 3 driving the tuner through gearing 5, 8, 11 and an indicator consisting of a flexible strip-like scale 22 coiled at each end round a spring-urged drum 18, 19 behind the control panel and a third drum 15 driven by the control spindle, adapted, as by projecting teeth 16, 17 to drive the strip-scale in one direction or the other by engaging a portion between the two coiling drums. Examples are given of gearing suitable for tuning by turning a knob, by operating the edge of a drum, and another by operating a tuning means involving longitudinal movement such as of cores or screens
