  • Patent number: 4256312
    Abstract: An air supported turntable assembly comprises a rotatable member having a center pin thereon and a stationary member secured to a base plate of a record player. One member is made in a frustoconical or conical configuration with its axis aligned with the axis of the center pin. The other member is made with a frustoconical or conical recess which is complementary to the configuration of the one member. The recess receives the one member with its axis aligned with the axis of the center pin. A plurality of orifices are formed in the inclined portion of the stationary member to discharge air uniformly toward the inclined portion of the rotatable member. The arrangement is effective in preventing any off-center movement of the turntable in operation.
