Abstract
An anti-skating device is provided for a phonograph turntable of the type including a base, a post extending longitudinally from the base and a tone arm supported for rotational movement about the post. The device comprises an elongated weight disposed about the post, means extending between the weight and tone arm connecting the two whereby the tone arm rotates with the weight, and means for applying a torque to the weight tending to rotate the weight about the longitudinal axis of the post to thereby apply a torque to the tone arm counter to the skating torque of the tone arm.
