b'Bernon PerkinsBernon George Perkins was hired by dAS as a farm manager in the mid-1930s, and since cedar poles were scarce, he began using creosote-treated poles. Within a relatively short period of time, preservative-treated poles became the mainstay of this new building system. In his textbook titled Farm Buildings, author John C. Wooley (1941) introduces pole-frame as the simplest type of barn frame. Wooley states: in many of the newer structures using this type of frame, treated poles are being used, and a footing is provided for each pole. Contrary to this statement by Wooley, the use of footings was actually relatively rare at this time.Perkins is attributed with two other developments of the modern post-frame building system. He was the first to place 2- by 4-inch boards on-edge as purlins, and he was the first to overlap purlins. By installing purlins-on-edge, Perkins was able to increase both rafter and purlin spacing. Overlapping of purlins led to more rapid construction and an improved purlin-to-rafter connection. In 1949, Perkins applied for a patent on a pole-frame building designed for storing and drying hay, grain, and other commodities. The patent was granted in June, 1953 (Patent No. 2,641,988). Figure 1 from this patent is reproduced in Figure 1-4 and shows the lapped,2-by 4-inch on-edge purlins characteristic of Perkins buildings. Online Educational Certification AVAILABLE NOW!
