Title: Automatic record player mechanism for turntable speed and pick-up arm position adjustment

Abstract: Mechanism for an automatic record player or record changer for combined adjustment of the turntable speed and the lowering position of the pick-up arm, the lowering position of the pick-up arm being established by engagement with a lever step of a two-armed pivotable shift lever, which step has been selected by a record diameter sensing means. The free end of a single arm dead-center lever engages the shift lever at one of two possible speed settings. During pivoting of the shift lever to bring a lever step for a different dropping diameter (17 cm) into the path of the pick-up arm, the free end is pivoted beyond dead center by said lever and is swung against the switch by an over-center spring to change the speed.
