Abstract

516,801. Wireless receiving apparatus. KOLSTER-BRANDES, Ltd., and LAWRENCE, R. S. July 8, 1938, No. 20288. [Class 40 (v)] The wave range switch 1 of a radio receiver equipped with push-button tuning is coupled over a pulley and cord 19, 18 and spring 20 to the latch-bar 9 which normally keeps depressed any push-button 12 which has been operated, whereby any movement of the switch 1 from its " automatic " tuning position both changes over from push-button to manual tuning on any of the wavebands provided for, and simultaneously releases all depressed push-buttons. Alternatively a cam on the spindle 1 may operate the latch-bar 9 in any manner. The spring 20 allows for further movement of the switch 1 to its other positions after the bar 9 has been released on the first wave range step S.
