Abstract: An umbrella-type stacking spindle for a record changer with end-stop function for the playing mode. Groups of clamping and supporting levers are accommodated in a tube, and move outward in response to movement of respective clamping and control sleeves during a changing cycle. The sleeves are separately movable with respect to a single actuating rod, which is controlled by the changing device. The control sleeve is locked to the tube for a given range of movement of the actuating rod, while the end-stop function is signalled by blocking movement of the actuating arm.

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.
