It was built in 1903 as the factory of the Edwin Harrington, Son and Company hoist manufacturer.","why_significant":"The nomination argues the building is the former quarters of one of the two oldest hoist manufacturers in America that kept its original corporate identity, and the oldest known extant hoist factory in Philadelphia. It also cites the building's steel-frame construction as a state-of-the-art industrial design for its time, and the firm's history as an example of success and failure in 19th- and 20th-century American industry.","narrative":"Built in 1903 at Seventeenth and Callowhill Streets in Philadelphia, this five-story brick industrial building served as the factory of Edwin Harrington, Son and Company, a hoist manufacturer. Its interior uses a steel frame of built-up columns on the lower four floors, with wooden beams on the top floor, and its large windows give open floor space and light. The firm traces its roots to a machine tool shop established in 1867, and it began producing hoists in 1875. The Peerless Hoist, first patented in 1905, became the company's main product. The building is regarded as the only surviving hoist machine shop in the city from that era, and a Harrington screw hoist from 1894 remains in place on an upper floor. The Harrington Company later moved to Plymouth Meeting in 1954.","period_of_significance":"1903-1954","architect_builder":"Roydhouse, Arey & Co.
