Abstract
Abstract This invention pertains to an improved barbecue grill constructed on a welded angle iron frame. The grill incorporates expanded metal sides preventing inadvertent contact with the heated fire box. The fire box is movably mounted on angle iron cross members which serve as a fire box track permitting shifting of the box relative to the grill. A tiltable hood is mounted on wing nuts at the center of two cross members permitting a tiltable reversal of the relative position of the hood.
