Abstract

Abstract A cooking structure comprising a pair of elongated insulated ovens spaced apart one above the other with individual doors at their adjacent ends, and a common upright flue at their opposite ends, there being removable grills between top and bottom of each oven. The lower portion of the lower oven forms a firebox with an outlet for the products of combustion at one end which may discharge into the flue or into the lower part of the upper oven according to the setting of a manually-adjustable damper. The upper oven has a horizontal passageway extending above the oven grill for the full length of the oven with a connection to the flue. Means are provided for supplying water or sauce to a grill in the upper oven and for discharging the same from the lower portion thereof. Preferably both ovens are enclosed in a sheet metal casing with inlets for an air supply to the firebox in the lower oven. The cooker eliminates continuous personal attention to broiling or barbecuing operations, moistens smoke from the logs or charcoal in the firebox which flows around meat on the grills breaking down tough fibers and permitting the natural juices to saturate the inner portions and outer surfaces evenly flavoring and cooking the meat without basting or turning the meat which is thoroughly tenderized and given an attractive color.
