ABSTRACT OF THE DISCLOSURE A vibratory feeder has a base mass supported upon vibration isolators. A feeder bowl mass is supported above the base mass. A plurality of leaf springs have one end connected to the base mass and an opposite end connec- ted to the feeder bowl mass. These springs are inclined to both the vertical and the horizontal and arranged to cause relative vertical movement between the masses in response to relative rotational movement between the masses about a common vertical axis. A driver, mounted on one of the masses, has a substantially horizontal shaft with a plural- ity of eccentric weights mounted at opposite end portions of the shaft for rotation therewith. A plurality of supports mount the driver and constrain oscillation of the driver about a vertical axis, relative to the mass on which the driver is mounted, under the action of forces generated by driver operation. The supports are operative to permit oscillation of the driver about a horizontal axis, relative to the mass on which the driver is mounted, under the action of forces generated by driver operation. Thus, the driver imparts to the mass on which the driver is mounted oscillating rotational impulses about the vertical axis. These impulses cause the feeder bowl mass to rotationally oscillate about the common vertical axis and to move up and down. Articles are progressively fed upwardly along a helical track within the feeder bowl by the oscillations of the feeder bowl mass. -1a-
