Heggie-Simplex Boiler Co. Joliet, Illinois Heating Boiler Division of James G. Heggie & Sons, Manufacturers of Steel Boilers of all Kinds for over Thirty-six Years Representatives in Principal Cities HEGGIE-SIMPLEX HEATING BOILERS For Burning Soft Coal Smokelessly For Soft or Hard Coal, Coke, Cos or Wood For Burning Oil During the thirty-six years covered by the activities of Jas. G. Heggie & Sons, boiler design has been perfected in its fundamentals. The Heggie-Simplex Boiler is the last step in this evolution. In it there is no compro mise with traditional features. It is the embodiment of a scientific study of all known .heating principles and requirements. The Heggie-Simplex Boiler combines in one portable, electrically welded steel unit* all the recognized advantages of both firebox and return tubular, double pass boilers. It has four distinctive features of fundamental importance: 1. An extra large firebox and a maximum of direct heating surface. 2. A secondary combustion chamber that provides ample room for complete com bustion before the flues are reached. 3. A "rear-front-rear'* flue passage for the gases. 4. A single, unimpeded, freely circulating body of water.' Correct heating principles find their most perfect expression in this boiler design. It secures as complete combustion of any fuel as ever has been attained in a heating boiler, with full application of its heat units. Needless to say, Heggie-Simplex Boilers are more economical of operation than other types--in fuel consumption, number of firings, and ash handling. They are also economical of space, because of their com pactness, the rear smoke outlet, and the front tube cleaning feature. No finer materials are : a. used in any heating boilers, and none are fabricated more expertly or with greater care. While built to A. S. M. E. requirements, in a number of points they exceed these stand ards. They may be installed with unex ampled ease, requiring no bricking, packing or , other costly operations. Heggie-Simplex Boilers are -guaranteed to develop the capacities listed on the following pages, at the point of most economical fuel consumption. They are based upon a standard for steam of two pounds pressure at the ' boiler, and for water upon a mean temperature of 180 deg. fahr. as the water leaves the boiler.
