Tuning indicator for radio receiver - has two=part lever hinged to scale support and scale slide, with slot for control element pin

摘要

The radio tuning indicator has a control element connected with the receiver's tuning elements. The control element is movable to-and-fro during tuning processes using a knob on the scale support whose drive shaft is in the same direction as the element's motion. A long and a short lever part (1, 2) are joined together through a hinge (3). The short lever part (2) is connected by a further hinge (4) to the scale support (5). The long lever part (1) is connected through a hinge (6) to a scale slide on the scale support (5). The end of the short lever part (2) has a guide slot (10) for the pin (11) of the control element (12).
