ABSTRACT:
An apparatus for a single feeding of an unattended pet out of an initially hermetically sealed can of pet food is disclosed. The apparatus includes an electric motor-driven can opener arranged in a housing, and a presettable timer which operates a switch to close the energization circuit for the motor at the time the feeding is to take place. The can-opening mechanism includes a cutter blade and can-turning gear combination, a vertically reciprocatable slide member supporting the cutter blade and a cam follower, and a power gear and box cam combination driven by the motor for vertically displacing the cam follower. In operation, when the motor is started to effect rotation of the gear, the cam forces the cam follower and therewith the slide member downwardly slightly, so that the cutter blade is forced through the lid of the can at the beginning of the cycle and is then held there while the can turns to sever the lid from the body of the can. At the end of the cycle, a rise in the cam raises the cam follower and the slide member to retract the cutter blade upwardly and thereby to release the can and concurrently to open the motor energization circuit. A ramp is provided below the cutter blade and turning gear combination for guiding the lidless released can to a receiving location outside the housing where the can will be accessible to the animal to be fed. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
