The Fitz Water Wheel Company specialized in the manufacture of water wheels and small power plants. John Fitz (1847-1914), who succeeded his father as head of the firm, developed the modern steel overshot water wheel. Fitz aimed its product at farmers, small millers, and small town hydroelectric and pumping stations in the United States and abroad. The spread of rural electrification cut into Fitz's market, but John Samuel Fitz, who had succeeded his father in 1914, kept the firm in business by shifting to production for "show" rather than productive use. The firm made many model wheels and turbines for engineering schools and historic restorations of working mills.

The Harlan & Hollingsworth Corporation began in 1836 as a railroad car manufacturer founded by Mahlon Betts and Samuel N. Pusey. Samuel Harlan joined the firm in 1837, and Elijah Hollingsworth followed in 1841. That same year, Harlan purchased Pusey's interest.

This new location enabled the company to produce three to four thousand bottles of fruit juice syrup a day. The product was entirely produced and stored in the factory until shipping, with separate rooms for pressing fruit, mixing the syrup, filling bottles, and inventory storage. The Hay’s Fruit Juice Company photograph album contains photographs and advertisements. The photographs are primarily of the factory’s interior and have accompanying captions on the facing pages that describe the manufacturing process of Hay’s Five Fruit. There are two photographs of raspberry fields and workers. The advertisements and labels are for the company’s fruit juice syrup.

The oral histories presented here document the research and development processes that transformed Kevlar from a novel polymer in the laboratory to a life-changing product in the marketplace. Through many surprising twists and turns, the people profiled here managed to make Kevlar serve the complicated and occasionally contradictory interests of the DuPont company, scientific inquiry, the marketplace, and the general public. Their stories are a rich study in the business and technology of innovation. Interviews were conducted by John Kenly Smith, PhD, in 2014 and 2015. Special thanks to the 1916 Foundation, the friends and family of Mary Laird Silvia, and individual donors for support of this project.

Kelvinator Corporation electric refrigerators album
Kelvinator was founded in Detroit in 1916 after previously operating as the Electro-Automatic Refrigerating Company. Nathaniel B. Wales (1883-1974) was the founding engineer, and he had been developing home refrigeration units. He received financial backing from automobile executive Arnold H. Goss. The company name was an ode to the British physicist who developed the absolute temperature scale that also bears his name, Lord Kelvin. By 1923, Kelvinator controlled 80% of the electric refrigerator market. In the 1920s, Kelvinator acquired both Leonard Refrigerator Company and Nizer Corporation. In 1937, it merged with Nash Motor Company and became a division of Nash-Kelvinator. The company expanded into other household appliances like hot water heaters, room air conditioners, and electric ranges. In 1968, Kelvinator was purchased by White Consolidated Industries, which in turn was purchased by A. B. Electrolux in 1986. This album appears to be a wholesaler's catalog showing sketched illustrations of the exteriors and interiors of Kelvinator refrigerator models in the D, S, and U series; three of the prints show only compressors and motors. No price list or text is included.

This letterbook contains tissue copies of the outgoing correspondence dating from 1899 to 1903 of inventor and manufacturer E. E. Hendrick (1832-1909). Although nominally dealing with his actions as president of the Hendrick Manufacturing Company, most of the letters concern personal business, such as purchases of household goods and cigars. Most importantly, they reveal Hendicks' interest in early automobiles, with correspondence with dealers and suppliers. Hendrick tried both electric and steam automobiles, and many of the letters are in the nature of complaints over such things as inadequate horsepower, poor riding quality, or the wrong size of tires. The letterbook has not been digitized in its entirety. The online collection comprises only the correspondence relating to automobiles. Image: E. E. Hendrick to American Electric Vehicle Company, 1900-08-01.
Locomotive Coaling Stations, Link-Belt Co. booklet of cyanotype photographs
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. It was later introduced in industry wherever endless-belt motion was required, particularly for elevating and conveying grain, coal, etc. Out of this grew the manufacture and design of machinery used in all sorts of conveyors and elevators, making the company the foremost of its kind in the world. This item is a booklet of 11 cyanotype photographs of locomotive coaling stations designed, erected, and equipped by the Link-Belt Engineering Company. The views include coaling stations in Croton, East Albany, and Lyons, New York; Philadelphia, Pennsylvania; and New Buffalo, Michigan built for the New York Central and Hudson Railroad, the Philadelphia and Reading Railroad, and the Chicago and Western Michigan Railway Company.

In 1877 they moved to Philadelphia and reorganized the firm as the Levytype Company. Here, they introduced their invention of a new photochemical engraving process, which they called "Levy-type". Other inventions followed, including the engraved glass grating known as the "Levy line screen," which became universally used for producing half-tone photoengravings; the acid blast, or etching machine; and the etch-powdering machine.
