Abstract
A stove firebox has a longitudinal opening in its bottom wall in which is supported upper and lower grates. The lower grate is slidable relative to the upper grate. Each grate has longitudinally spaced cross bars, and such cross bars and the openings therebetween have the same longitudinal dimension whereby upon offsetting the cross bars of the two grates longitudinally, an imperforate floor is provided and upon alignment of the cross bars, vertical passages are formed to sift ashes downward for cleaning the firebox. The slidable grate can be reciprocated to provide the sifting step. An interior draft inlet is provided at the bottom of the firebox adjacent the front.
