Abstract

A suspension system provides a motion damping mounting for carrying a record playback machine comprising a plurality of damping ring assemblies, each having an elastic ring for fastening between a machine and a support, the rings being flattened when secured such that opposite segments of each ring extend substantially straight and parallel such that a component of stress applied to the machine in the direction of the straight segments produces limited rolling movement of a flattened ring, which damps motion of the playback machine in the direction of the straight segments of the flattened ring, the flattened ring also damping motion of the machine vertically and laterally relative to the direction of the straight segments. According to this invention, the damping assembly includes a ring and mounting plates or clips and fasteners for securing the ring to the machine or the support.
