Abstract
Abstract The application discloses an automatically controlled cooking and dispensing apparatus for hamburger and the like. A timer device controls air valves for starting and reversing a meat conveyor which is enabled by an air cylinder and a baffle member to pick up patties of the meat product one at a time. The air valves are controlled during the timing period to place a pair of heating elements in cooking position and at the end of the period to withdraw the elements therefrom. Optional means are provided for automatically positioning the meat supply cylinders in conveyor pickup during operation of the apparatus.
