This main conveyoralso will take care of the ashes from the furnaces. Ash pitsof bowl-shape are located in tne boiler foundations below thestokers from which the ashes may be scraped out into theconveyor passing in front, and then by adjusting the dumpercarriage properly they are dumped into the ash bin above,ready to be loaded into cars outside. The main bucketconveyor is operated by a TV2 horse-power electric motor, alsofurnished by the Milwaukee Electric Company, through aspecial set of equalizing gears transmitting an even conveyor travels on a track of 16-lb. T-rails. The entireconveyor system, and aiso the coal crusher, were supplied bythe Link-Belt Engineering Company, Philadelphia, for the lining of the surfaces exposed to the Are, exclusive ofthe flue. To five of the six boilers, the Mansfield travelling chain-grate stoker has been applied, which was also furnished bythe Aultman k Taylor Machinery Company. The Mansfieldstoker consists of a wide band, or chain, made up of shortlink-like sections of grate bars pivoted after the fashion of asprocket chain, which band travels around two drums in thefire-box, being so driven that the upper side moves backwardfrom the boiler front toward the arch. Coal is fed evenlyon to the moving chain as it recedes by a feeding hopper out-side the front, which hopper is supplied directly by the coalchutes leading from the coal pockets above. The coal burnsas it travels with the grate, the speed of travel being so ad-justed that when rear drum is passed the coal is entirely con-sumed, leaving ashes only to oe dumped off at the end—thisentirely obviates cleaning fires. The stokers are dri
