The Link-Belt Company was founded by William Dana Ewart (1851-1908), who had invented the detachable link-belt in 1874. The flexible metal belt provided a superior system of power transmission and was first used widely in farm machinery. This item is a booklet of cyanotype photographs of locomotive coaling stations designed, erected, and equipped by the Link-Belt Engineering Company.

Richmond Machine Company is an equipment manufacturer located in North Philadelphia. In around 1953, the Richmond Machine Company acquired the American Pulley Co. for the use of its patents. The American Pulley Co. was a power transmission equipment manufacturer which had its start as a pulley provider in Philadelphia, Pennsylvania, in 1892. This collection consists of two parts, the American Pulley Co. and Richmond Machine Company, the latter comprising only a small portion of the records. Within the American Pulley Co. series, researchers will find photographic prints of various hand and lift trucks, power transmission equipment, and non-mechanical products produced and distributed by the American Pulley Co. Researchers will also find images of facilities and employees demonstrating equipment for advertisement purposes. This collection transitions to the Richmond Machine Company, which bought the American Pulley Co. around 1953 and incorporated these photographs into their personal inventory. Included within this series are instructions, guides, and videos pertaining to drum and barrel reconditioning. Produced for both outside companies and personal sales, products within this collection demonstrate the role the American Pulley Co. played in early industrial development. Researchers interested in power transmission equipment would find this collection useful.
