  • Video disc turntable having clamping device
    Patent number: 4562570
    Abstract: A turntable for use in a video disc playback unit includes a hub assembly adapted to fit within a central spindle aperture in the disc. The disc is secured in position by a plurality of clamp members pivotally mounted for movement in a radial direction around the circumference of the hub. When the turntable is at rest the clamp members retract into the hub to allow installation and removal of the disc. As the rotational speed of the turntable increases, centripetal force causes the clamp members to swing radially outwardly to engage the disc, thereby clamping the disc to the rotating turntable.
