Motion damping suspension system for record playback machines

A motion damping suspension system for mounting a machine, such as a record playback machine, vertically above a movable support comprising:

• movable support members providing substantially flat, horizontal supporting surfaces;
• machine mounting members providing substantially flat mounting surfaces substantially parallel to and above said supporting surfaces;
• a plurality of elastic rings secured between said machine mounting surfaces and said support supporting surfaces with said elastic rings in flattened condition between said surfaces and the axis of each ring arranged substantially horizontally and opposite segments of each ring adjacent said mounting and supporting surfaces extending substantially horizontally;
• means for securing a portion of one of said horizontally extending segments of each ring to the machine and a portion of the other of said horizontally extending segments of each ring to the support to support the weight of the machine by compressing vertically extending segments of each ring such that stress applied to the machine having a component in the direction of the horizontal segments of a flattened ring produces limited rolling movement of said horizontally extending segments of the flattened ring along said mounting surfaces and said supporting surfaces which damps motion of the machine;
• said flattened ring also damping motion of the machine vertically and laterally relative to said direction.
