ABSTRACT OF THE DISCLOSURE A vibrating machine, such as an oscillating conveyor, vibratory feeder, or vibratory screen, is mounted to a plurality of supports by a suspension that isolates machine vibrations from the supports. The sus- pension includes a plurality of U-shaped stirrups extend- ing transversely beneath the machine at intervals spaced longitudinally of the machine. Each U-shaped stirrup extends between a pair of opposed supports to which the stirrup is mounted for pivotal movement about an axis of rotation that extends transversely of the vibrating machine. This axis of rotation is along or near the axis of the instantaneous center of rotation of the stirrup. The stirrups support the vibrating machine at points spaced below the axis of rotation, and vibrations in a direction longitudinal of the vibrating machine impart a rotational motion to each stirrup. Thus, such vibrations are not transmitted to the supports. In a preferred embodiment, resilient bushings are fitted within the U-shaped stirrups coaxial with their axis of rotation, vibration dampening resilient means are provided for mounting the vibrating machine upon the stirrups, and the stirrup surfaces supporting said resilient means inter- sect an axis that is parallel to the axis of rotation and that passed through the region of the center of percussion of the stirrup about the axis of rotation. -1a-
