Description
Wilson and Smith's patent "consists in a certain novel mode of constructing, arranging, and moving the bars and other parts which constitute furnace fire-grates, by which the following desiderata are secured: first, the fuel during combustion, and as it is burnt down,' is carried towards the flue leading to the chimney; second, the spaces for the admission of air between the bars are maintained in a free and open condition all over the fire-grate; third, the formation of 'clinker' on the bars is prevented."
