Summary
DescriptionLombard steam log hauler.jpg |
English: Lombard Steam Log Hauler
"Designed, patented (1901), and built by Alvin C. Lombard (1856-1937) of Waterville, Maine, eighty-three 'Lombards' were the first practical examples of the often-tried lag or crawler tread that would become the mark of the internal combustion engine-driven agricultural and construction equipment and military tanks in current use." Lombard's first log hauler had an upright boiler and two upright engines, but these were later made horizontal. It became "a railroad yard engine, known as a saddle back". It had a cab in front for the steersman and one at the rear for the engineer and the fuel. Typically, it had a four-man crew engineer, fireman, conductor and steerer. A bell rope was provided so that the conductor, near the rear, could communicate with the front cab. The Lombard steam log hauler has been designated as a National Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers. |
