ABSTRACT:
A vibrator attenuator, especially for a compass. The vibration attenuator is situated to prevent transfer of vibrations from the fastening base of a compass, e.g. from the framework of a boat, to the compass rose, to prevent revolving of the compass rose that results from such vibrations, and to prevent transfer of external impacts to the compass rose itself. The vibration attenuator is disposed between a supporting rod of a bearing of the compass rose, and a frame of the compass, so as to resiliently interconnect the supporting rod and frame. The vibration attenuator is preferably attached to a supporting bridge in turn affixed to the compass frame. The vibration attenuator may be an elastic member or a spring, which is attached to the supporting rod and to the supporting bridge, so that the vibration attenuator is resilient in both a vertical or longitudinal direction, and in a lateral or horizontal direction.
