Abstract
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 suspension includes a plurality of U-shaped stirrups extending 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 surfaces spaced below the axis of rotation. These stirrup surfaces are located to intersect an axis passing through the region of the center of percussion of the stirrup about the axis of rotation. 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, and vibration da…
