Terry, who began experimenting with a new type of steam turbine engine in the year 1888. Mr, Terry applied for bis first turbine patent in 1892, and others followed in 1899 and succeeding years. By 1903, with a shop consisting of an engine lathe, a milling machine, and a planer, he was producing a turbine a month. In 1906 the business was incorporated under the present name. The business grew rapidly and additional designs and types were added, including multi-stage machines for bleeder and mixed pressure operation. Today this company is the only concern in the United States that concentrates its output on steam turbines. Its machines are in use throughout the world. Timken Roller Bearing Co............... 200 In the 35 years that this company has been making tapered roller bearings, ex clusively, its field has expanded so broadly that it has become the largest manufacturer of roller bearings. Over 90^5> of the world's manufacturers of automobiles and motor trucks have standardised on tbese bearings for the points of hard service and their appli cation to industrial machinery has increased so rapidly over the last decade that there is no type of equipment in which these bearings are not used. These applications range all the way from the precision work on machine tool spindles to heavy duty jobs of steel mill roll neck applications. The company makes its own steel and has become one of the largest alloy steel manufacturers. Titeflex Metal Hose Co........----- 201 This company was organized in 1916 to develop a flexible all-metal tubing on a radically new principle in which pioneer work was necessary to develop to a satisfac tory commercial conclusion the many details encountered.

Both fire and water tubes are manufactured in a wide range of sizes, pressures and types, also auxiliary apparatus such as water walls, air heaters and economizers., Union boilers have many distinct advantages, this company having pioneered in the development of the radiant heat type boiler--an outstanding achievement in boiler practice. United Conveyor Corp'n......... 204,205 Represents the combined experience of five companies, ait specializing in soot and ash handling by air through pipe line conveyors, and dating back to the origination of this type of system. In the last five years, how ever, United brought out the "Nuveyor" and the "Steamatic" Ash and Soot Conveyors, which have largely displaced former methods in this field. The reasons for this progress can best be found by visiting jobs where these two new systems are operating--there are now several hundred installations. United States Hoffman Machinery Corp'n......................................... 206 Manufactures diversified group of ma chinery products. Known for thirty years as largest manufacturer of garment pressing machines. Hoffman miniature steam boilers lead all others in sales.

Centrifugal products designed and built in Hoffman factory by engineers with many years of specialized experience in this field. V Vogt, Henry, Machine Co................ 208 The initial effort of this fifty-three year old company was devoted to a genera] ma chine shop business and the manufacture of tubular boilers. Constantly increasing de mands for its products led to expansion into related lines. Today, operating a completely equipped plant occupying nineteen acres, its market for water tube boilers, refrigerating equipment, heat exchangers, drop forged steel valves and fittings and refinery equip ment is world-wide. W Westco Pump Corp'n........................ 206 Westco engineers originated the turbine- type pump which is well known for its abil ity to produce higher pressures in single stage at standard motor speeds and for its wide operating range characteristic.

Wing, L. J,, Mfg. Co......................... 216 Back in 1903, L. J. Wing, founder of this company originated the idea of combining a propellor fan with the steam turbine rotor for driving it. This was followed by a gradual development of the propeller fan for venti lation and forced draft in all its phases, cul minating in the well-known line of Win,;Scruplex Fans and Exhausters. Wing turbine and motor-driven blowers and small turbines. Again in 1922, they took the lead in de veloping unit heating, finally perfecting a uniquely efficient system which is as effec tive in heating industrial buildings of eveo the greatest height. Worthington Pump & Machinery Corp'n...................................... '. 22C In 1840, Henry R. Worthington invented the direct-acting steam pump and in 2$41 opened his manufacturing plant.
