A. D. Granger Go. Established 1S93 19 Park Row New York City Boilers, Engines, Feed Water Heaters, Pumps, Stacks, Grates Steel Plate Construction, Cranes, Hoists, Complete Plants-. "Oswego" Water Tube Boilers Type "A," Up-Draft A self-contained, internally fired,Water Tube Boiler, with straight inclined water tubes . connecting front and rear water spaces. Inner and outer shells form a com plete water jacket surrounding the fire. Steel construction, no cast iron used in boiler proper. Built in both up-draft and down-draft types. All under A.S.M.E. Code for working pressures up to 150 lbs. - Type "A," for anthracite coal, up-draft is made in 22 sizes, both low and high pres sures, ranging from 20 H. P. to 300 H. P. or an equivalent in radiating surfaces of from 2000 sq. ft. to 30,000 sq. ft. Type "B" is a development from Type "A," to include the down-draft water grate for the smokeless combustion of bitumin ous coal. Also made in 22 sizes with radi ating surfaces from 2000 sq. ft. to 30.000 sq. ft. ' Type " B," Down-Draft Type "W." A welded unit, built for 15 ; tbs. working pressure, under the A.S.M.E. Code, made in 20 sizes to carry from 2000 sq. ft. of radiation to 30,000 sq, ft. This is built with either vertical or horizontal ' baffles. Space--Oswego Boilers are compact and occupy very small space per horse power. Designed for Maximum Fuel Economy and to obtain highest efficiency. The furnace is entirely surrounded by water surface and the water tubes take the direct heat from the fire as well. The gases of combustion must pass across the bank of tubes three times to the smoke outlet. Designs for Oil Burners and Natu ral Gas. We have units operating with all the best known oil burners and several in stallations with gas burners.

P.......... TRADE MARK REGISTERED 600 U5V Boilers, Steel Heggie-Simplex Boiler Go. Joliet, Illinois Heating Boiler Division of James G. Heggie & Sons, Manufacturers of Steel Boilers lor Over 39 Years Representatives In Principal' Cities For Mechanical Firing The introduction of Heggie-Simplex Boilers marked the beginning of a new era in heating boiler design and construction. While widely imitated today, they embody the simplicity in design upon which the durability, that has made them so popular, depends. Patents protect this superiority. The crown and side walls of the firebox and auxiliary combustion chamber are made from a single plate--there are fewer plates, and fewer seams in Heggie-Simplex Boilers than in other boilers of: this popular, type. . While built to conform with the A. S. M. E. Code, its requirements are minimum only in Heggie-Simplex specifications. For example, where the Code calls for }/i" plate, Heggie- Simplex employ Y\ . All openings are rein forced with forged steel flanges. Bases are made of steel channels. Similarly, every de tail affecting greater strength and longer life is incorporated. . S. H. B. I. Ratings Heggie-Simplex Boilers are rated in con formity with the "Steel Heating Boiler Insti tute's Code for Rating Low Pressure Heating Boilers." These ratings are the total radiation-load at the boiler outlet; expressed in square feet of cast iron radiation. Steam ratings are based upon the emission of 240 B.t.u. per hour per square foot of rating at 2 lb. pressure. Water ratings are based upon the emission of 150 BT.u. per hour per square foot of rating at 180 deg. fahr. To determine the Heggie-Simplex Boiler re quired to heat a building, add the following: (I). .the direct radiation, (2) the equivalent to compensate for losses through water heaters or other apparatus connected to the boiler, (3) and the equivalent to compensate for losses through piping connecting the radiation, water heater and other apparatus to the boiler. Then select a size with a rating equal to this total load. Send for catalog to obtain more de tailed information and specifications. 601
