H.K. Porter, Inc.

H.K. Porter, Inc. (Porter) manufactured light-duty railroad locomotives in the US, starting in 1866. The company became the largest producer of industrial locomotives, and built almost eight thousand of them. The last locomotive was built in 1950, but the company continues to produce industrial equipment to this day.

Porter was known for building locomotives for industrial railways, which were often small enough that they could be operated by one person. Porter built mostly steam locomotives, but also some gas- and diesel- engined locomotives, and some that ran on compressed air.

History

Henry Kirke Porter

H.K. Porter locomotive Eau Claire built in 1868

In 1866 Henry Kirke Porter formed a partnership with John Y. Smith, forming the company Smith & Porter. They opened a small machine shop on 28th Street in Pittsburgh, Pennsylvania, and begin repairing and building industrial equipment. They received an order for their first locomotive on March 4, 1867, and built the Joshua Rhodes for the New Castle Railroad and Mining Company. They went on to build 43 locomotives together, including the Minnetonka which is preserved at the Lake Superior Museum of Transportation. They specialized in four wheeled, saddle tank locomotives for small industrial railroads.

On February 7, 1871 a fire broke out in the shop destroying twelve locomotives under construction, the shop, and 23 adjacent structures. The losses were estimated at $200,000, and the partnership was dissolved. Smith formed Smith & Dawson Locomotives, which became National Locomotive Works. Porter formed a partnership with Arthur W. Bell, called Porter, Bell & Co. and they built their first locomotive for the Jackson Furnace Co. of Michigan. They expanded their range to include light passenger engines and small freight engines, primarily for narrow gauge railroads. They built 223 locomotives, until Arthur Bell died in May 1878.

Porter continued the business on his own, as H.K. Porter & Co. He had established a reputation as a builder of rugged, specialized locomotives and the company could custom build a locomotive quickly and efficiently, with a system of interchangeable parts; pistons, wheels and boilers in various sizes that can be combined to suit a customer's requirements. Some of the basic designs were kept in stock, and could be ordered off the shelf.

In 1890, Porter built their first compressed-air locomotive, for a coal mine in Pennsylvania. Air was stored in two tanks, and used to drive the pistons instead of steam. Coal-fired locomotives were unsuitable for use underground because they produced dangerous fumes and could start fires. Porter went on to build over 400 compressed-air locomotives. Although other manufacturers built compressed-air locomotives, by 1900 Porter had captured 90% of the market.

In 1899, the company was incorporated as H.K. Porter Co., Inc and built a new plant at 49th and Harrison Street in Pittsburgh. Production peaked in 1906, with almost 400 locomotives built that year.

Porter built their first gasoline-powered locomotive in 1906, and in 1915 they built their first fireless locomotive, using a large pressure vessel to hold steam and hot water in place of a boiler. These proved to be more useful than compressed-air locomotives, and soon Porter dominated this niche market.

1919: Porter was selected to build twenty 4-6-0 45-class mainline locomotives for the Manila Railroad Company in the Philippines to replace its aging British tank locomotives. The class weighed 72 long tons (73 t) and were one of the largest locomotives built by the company. Its efficiency and low cost of maintenance led the Manila Railroad to use the Porter design for larger locomotives built by Alco and Baldwin.

1921: The H.K. Porter Co. was prosperous, enjoying a post-World War I reconstruction boom in Europe, and a road construction boom in the US. Porters were a favorite choice among grading contractors, who used light, portable tracks to carry the wooden tipper-cars that were the earthmoving equipment of the day. Henry Porter, still running the company at age 81, died on April 10.

1939: After a long decline, the H.K. Porter Co. declared bankruptcy. Thomas Mellon Evans purchased the company, determined to turn it around. He bought other manufacturing companies, adding them to his collection. Locomotive production increased again during World War II, and the company was recognized for its service to the country in 1942, but demand for steam locomotives dwindled post-war, and H.K. Porter became primarily a holding company for the many subsidiaries Evans had acquired.

1950: The company built its last locomotive, which was exported to Brazil. The parts business and all the required patterns were sold to the Davenport Locomotive Works in Iowa.

1950s–1960s: Electrical Division National Electric Defense Products Facilities manufactured rocket motor bodies for Nike family of guided missiles.

1969: The company acquired saw manufacturer Shurly & Dietrich, which continued operations until 1973.

Kalmbach collection

The largest collection of Porter photographs and information is currently housed in the Kentlein Porter Collection at the A. C.

Many of the 780 builder's photos, blueprints and other locomotive data were republished in Porter Steam Locomotives, published by the library.
