AN IMPROVED STEAM BOILER.
A steam boiler designed to give a maximum amount of heatingsurface, iu order that steam can be generated with tbe smallest possible amount of fuel, has been patented. The boiler is preferable set at an inclination, and each of its ends consists of a circular drum, through which extend flue tubes, passing through both front and rear drums, these flue tubes being surrounded by water tubes, opening- into the interior water spaces of tho drums. A mud-drum is arranged transversely under the lower side of the rear drum, with which it communicates through a short vertical pipe, arranged horizontally over boiler, is in communication with the top portion of the water-drums at both ends by vertical pipes. The tubes are expanded in the tube-sheets, and tho setting shown is designed to represent about the proper angle to assure the best circulation. When the boiler is filled the water in the drums and tubes entirely surrounds the flues, and the products of combustion, after circulating around the tubes until they reach the rear drum, are deflected downward to its rear side, thence passing through the flues to the stack at the front, up which they I escape.
