Approximately 65 Circulars in two original cloth covered post bindings. Large 8vo. 265 mm. x 180 mm. Soiling on the first leaf of the first circular, but otherwise quite clean. Very Good. XLib. With the ownership stamp of the Engineering Society of York County, PA. The scope and content of these circulars is rather remarkable, as was the vastness of the company itself. The circulars were certainly ephemeral and are VERY SCARCE today, with only a handful recorded in public or private collections. 'Organized in 1886 as the Westinghouse Electric Company with a force of 200 men, the name of the company later became the Westinghouse Electric & Manufacturing Company. By 1904, the number of workers grew to 9,000 at the main plant with 3,000 additional employees in branch factories. It became the largest of the Westinghouse companies and was thought to be the largest and most modern workshop in the world at the time the American Mutoscope & Biograph Company filmed its operations. The Engineering Department alone employed 350 mechanical and electrical experts. The company began building an extensive plant in 1895 in East Pittsburgh on 40 acres of land. The total floor space in the entire plant was over two million square feet. The shop contained a long aisle in the main building 'filled with large machines in various stages of construction. This aisle [was] seventy feet in width and 1,184 feet in length, and [was] traversed from end to end by traveling cranes of capacities ranging from thirty to fifty tons each.' The largest aisle, measuring 70 feet across and one-third of a mile in length, was located in the East Machine Shop. The main function of the Electric & Manufacturing Company was to develop and produce apparatus for the generation, transmission and application of alternating current electricity for the railway & industrial fields. There are also some D.C. motors and devices described, as well as various lamps, etc. The Electric & Manufacturing Company played an integral role in several notable projects, namely the conversion of Niagara Falls to electric power, the installations of the Interborough Rapid Transit Company in New York and the South Side Elevated Railroad in Chicago, and the powering of the Louisiana Purchase Exposition in St. Louis.
