Union Iron Works

In 1915, Union Works announced that they were “manufacturing a small tractor weighing 1,600 pounds, with 12 B.H.P.” This outfit was of the gearless type, being devoid of gears chains, and sprockets. The design was unique but more or less impractical. As late as May 1918, Union Iron Works was still advertising their gearless tractor.

John E. and Edwin L. Lockwood, along with Charles H. Upton, formed the Union Iron Works in 1900. As founders and machinists, Union Iron Works rapidly rose to prominence. About 1911, the “Skibo” tractor appeared. It was the same basic machine that was concurrently offered by Universal Tractor Company at Stillwater Minnesota, and the Minneapolis Threshing Machine Company at Hopkins When Rumely of LaPorte took over Universal at Stillwater, the other builders lost their license to build “Universal” tractors. In 1915, Union Iron Works brought out a small “Gearless” tractor, but it had little impact on the market.
