ABSTRACT:
A power operated can opener includes a hand lever which pivots on the can opener frame to carry a cutting element into and out of cutting position. A can feed wheel is carried on a motor driven shaft which is supported for limited vertical movement within a tapered, elliptical bore in the frame. A spring biased switch control lever is pivoted to the back of the frame in contact with the feed wheel shaft. When the cutting element is moved against the lid of a can, the downward force on the feed wheel displaces the shaft downwardly and pivots the switch control lever against the motor switch to initiate rotation of the feed wheel before the can lid is pierced by the cutting element.
