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.
