Abstract: A device is disclosed for oscillating and vibrating a deep pan so that the contents in the pan are thoroughly and evenly cooked without the chef's continual attention. The device is moved back-and-forth via a lever arm connected to a rotating disc. The lever arm is connected to the disc by a lost-motion connection, in the first embodiment of the invention. In the second embodiment, the plate supporting the frying pan is moved back-and-forth via a crank arm pivotally connected to the disc, while the other end of the crank arm is pivotally connected to a connecting link, which is attached to the underside of the support plate. Rollers mount the support plate for movement, and may allow for compound movement of the support plate when casters are used. The compound motion is generated by mounting the rotating disc in a plane offset from the horizontal and allowing sufficient play to the rollers mounting the support plate.
