Abstract
Abstract An automated cooker for sandwiches and the like. The automated cooker includes a pair of heating elements spaced one from the other so as to provide passage therebetween. A motor drives a conveyor which carries a plurality of individual sandwich holders through the passage between the heating elements. Each sandwich holder consists of a handle which can be attached to the conveyor and a top portion which encloses the sandwich to be cooked. A bar is placed below the heating elements and extends along the length of the cooker. The bar is used to trigger a switch which activates the heating elements and which turns on a motor that drives the conveyor. The bar may be activated by the handle of any sandwich holder placed on the conveyor. The bar is deactivated so as to turn off the heating elements and the motor which drives the conveyor when the handle of the last sandwich holder reaches a notch placed in the end of the bar. A rack provided at the end of the sandwich cooker catches each sandwich holder as it emerges from the passage between the heating elements. The rack stacks the sandwich holders in sequence as they emerge from the sandwich cooker. Controls are provided for adjusting the temperature of the heating elements and for adjusting the speed of the motor which drives the conveyor.
