Title: Damping apparatus for damping the resonance of disc record tone arms

Abstract: A damping apparatus for damping the resonance of a disc record tone arm, comprises first and second relatively movable members in engagement with energy absorbing material therebetween. One of these elements has mounted thereon a skid assembly in which a cantilever arm is anchored to the element. The cantilever arm has substantial stiffness both longitudinally and in the plane normal to the record surface and also has substantial compliance transversely to its longitudinal dimension and torsional compliance. A skid pad is mounted at the free end of the cantilever arm, which skid pad has substantial stiffness in the direction tangential to the record trace.
