This patent was lost in the 1836 patent-office fire and not restored. Willard Earl's shingle mills were mentioned in a 1965 paper prepared by the Department of Research at Old Sturbridge Village, “New England Village Sawmills 1790-1840” by Barnes Riznik. “As early as the year 1821, and perhaps at an even earlier date, Willard Earle began the manufacture of his patented shingle machine at a small shop in Hubbardston, Massachusetts. In the 1830s, Earle's patented design was built by at least three other shopes, in Henniker and Franklin, New Hampshire, and in Westminster, Vermont, where machine builders had purchased Earle's patent right.” The references are given as Massachusetts Spy, August 15, 1821; Jonas Reed, A History of Rutland, Worcester County, Massachusetts (Worcester, 1836), p. 32; New Hampshire Patriot and State Gazette, September 21, 1829, May 30, 1830; North Star, May 31, 1831; Brattleboro Messenger, April 10, 1829.
