The Lombard steam log hauler, designed by Alvin Lombard, has been designated as a National Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers.
Ceremonies were held Aug. 14, 1982, at Patten, Me., site of the Lumberman's Museum. A tablet was unveiled, dating origin of the engine at about 1910, and stating:
'This steam crawler-tractor emancipated horses from the killing work of hauling trains of sleds over iced roads in the winter woods of the United States and Canada.
'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.'
In the earliest days of logging, the logs were floated down streams to mills. An attempt was made at using an internal combustion engine to power the haulers, but this did not work with wheels in loose snow. Another man had an idea for using track but did not get anything done.
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.
Lombard later turned to gas engines, and the only difference between his later log haulers and his earlier ones was in the mode of furnishing power. Gasoline, however, did not provide the pull of steam; where a steam engine would haul 12 sleds, a gasoline engine would pull five.
A diesel was built in 1934, but this was the last log hauler since trucks had supplanted the haulers. Lombard went out of business after 83 log haulers, of which three had gone to Russia. Some of the old machines were cut up for junk; others were abandoned, and some still stand rusting in forests.
One Lombard has been restored to running condition and can be seen at the Lumberman's Museum in Patten.

There were no brakes on a log hauler or on its train of sleds...nearly every road had its downgrade that made steerers pray that they should live this once more then they would find some other way to make a living. 'Yankee Magazine, March 1965.
This wood burning Lombard Log Hauler, built in Waterville Maine (circa 1900-1910) was in operating condition February 7, 1980. Took a 2 mile run performance superb. Owned by Frank T. and Theodore D. Crooker of Brunswick, Maine.
While Alvin C. Lombard was successful in patenting a log hauler that worked, other men had dreamed and failed to do the same. Their stories are told in the ASME brochure, and there may be lessons in them for today's inventors who have ideas and become discouraged.
James and Ira Peavey sought to provide power for a log hauler through two large screws. 'This worked on ice,' the brochure says, 'and a full scale model actually hauled logs on a good road, but the screw churned up the snow so much that it lost traction and in loose snow it was pretty near helpless.'
Johnson Woodbury sought to reverse the track of a 'horsepower', the kind of treadmill utilizing horses to provide power for a threshing machine or a drag saw to saw wood. Woodbury envisaged this assembly reversed, the track on the ground. A roller was built, but it proved impractical and was abandoned yet later it was found that Woodbury's snow plow would have been successful.
An even earlier attempt to solve the problem was proposed by Warren P. Miller, of Marysville, Calif., who obtained a patent in 1859. Miller designed his machine to run on sand rather than snow but the authors feel that what he described was the same traction system as Lombard's, patented over 40 years later.
