Abstract: The Westinghouse Machine Company engine records consist of repair records for equipment produced between 1881 and 1921.
The Westinghouse Machine Company was organized in 1881 as a manufacturer of steam engines, gas engines, steam turbines, and other mechanical equipment. The firm was part of the family of companies founded by the inventor George Westinghouse. Its factory was located at the Westinghouse Works in East Pittsburgh, Pennsylvania.The Westinghouse Machine Company commenced production of its first model, the Standard Automatic Engine, in July 1881. The Standard Automatic was a steam engine that could be custom-ordered in 13 sizes, varying from 5 to 250 Horse Power (H. P.) The smaller Junior Engine (7 sizes, 5 to 75 H. P.) was introduced in 1886, followed by the Compound Automatic steam engine (9 sizes, 35 to 300 H. P.) in 1888. The Westinghouse Machine Company also manufactured gas engines, steam turbines, and pumps.The company's engines were used to power a wide variety of industrial and mechanical applications, including pumping, cutting, blowing, and lighting. Manufacturing companies, railroads, electrical power companies, and sawmills were among the many firms that used Westinghouse engines in their daily operations. The Westinghouse Machine Company shipped its engines and pumps to companies throughout the United States, Europe, the Far East, Central America, and South America.
The collection consists of thirty-three volumes of manufacturing and repair records for equipment produced by the Westinghouse Machine Company between 1881 and 1921. The volumes, which are labeled "Duplicate Engine Records," were copied from the original records, apparently for the use of the company's Order Department. The records are arranged in five categories: Standard Engine; Junior Engine; Compound Engine; Gas Engine; and Special Engines, Pumps, and Miscellany. Each engine was numbered in the order of its manufacture. The records for each engine include the engine number, a shop order number, the date of manufacture, the size and speed of the engine, the parts numbers for the engine components, testing information, repair and maintenance orders, and the name and location of the company that purchased the engine. Some of the engine records include sketches and drawings of component parts.
