Boilers, Steel "Oil City" Smokeless Boiler "OIL CITY" low pressure boilers both riveted and welded types are offered to the trade as the last word in "Heating Economy and Reliability;" comprising in one com pletely assembled unit all the necessary elements of a modern plant for steam or hot water heating. These boilers are especially adapted for Schools, Office Buildings, Hotels, Churches, Hospitals, Theatres and Club Houses or for any purpose where the service of a universally recognized fire box boiler of high merit is desired. "OIL CITY" boilers are designed and constructed to meet all the requirements of modern engineering practices as for mulated by the American Society of Mechanical Engineers, the boiler laws of the various states and cities and are backed by over 50 years of successful practical experience. Description--"OIL CITY" boilers are built in smokeless and straight draft types both riveted and welded for portable and brick settings. Riveted boilers can be furnished with cast iron base ready for setting on foundations. Welded boilers, are equipped with an all steel base ready to receive the boiler thereby eliminating all brickwork. These boilers are constructed with large fire boxes thereby insuring ample com bustion space in which the heat-giving gases and air can thoroughly mix and burn before entering the tubes. The arrangement of tubes in relation to the ^hell allows free circulation of water at all times, and together with a liberal steam space insures an adequate constant supply of dry steam and a steady water level. Ratings--Ratings are very conservative, only such parts of the boiler coming in contact with the passage of hot gases on one side and havingwateron theother being considered as effective heating surface. Equipment--Equipment with all boilers includes, in addition to a complete set of sectional shaking grates, suitable to the type of coal used, all necessary castings, safety valves, steam gauge, water column; baffle arch or tile, etc., as may be required efor a complete installation. Oil-Fired--Where oil is to be used exclusively we strongly recommend our Series 1900 Portable Return Tubular Fire Box Oil Burning Boiler where a riveted boiler is desired and when a welded boiler is to be employed we recommend either our "Type" "X" or "Type" "W" three pass boiler all of which have an exception ally large fire box which is essential for the proper combustion of oil fuel. Every "OIL CITY" boiler bears the official stamp of the A. S. M. E. Boiler Code as well as that of the boiler insurance inspector who supervises the construction of the boiler in our shops. At a small increase in cost "OIL CITY" boilers are furnished, braced and stayed for a safe working pressure of.100 or 125 lb.
