The Thomas Ranck Round Barn is a round barn in Waterloo Township near the Fayette-Wayne County, Indiana county line. It is one of many round barns built in Indiana during the late 19th and early 20th centuries.〔 Of the round barns built in eastern Indiana during this period the Ranck Round Barn stands out as one of the most elaborately designed structures. The Thomas Ranck Round Barn was listed on the U.S. National Register of Historic Places in January 1983. Built in 1904, the Ranck Round Barn is a large and wood frame barn. It is part of a complex of buildings on the southeast portion of the McDivitt property in Brownsville, Indiana. Erected on a bank with a concrete foundation, the barn is in diameter, and is tall. The open structure consists of three circular tiers stacked on top of one another. The top section forms a cupola.〔 Thomas Ranck Round Barn, 83000030; National Register of Historic Places Inventory – Nomination Form; US Dept of the Interior, National Park Service; Washington, D.C.; January 11, 1983〕 Isaac McNammee constructed the Ranck Barn in 1904 for Thomas and Nancy Ranck. McNammee built several round barns in the area, and patented his design for a self-supporting conical roof in 1905.〔 The Ranck farm was purchased in 1937 by a local veterinarian and his wife, Ralph and Tena Carmack. In 1945, Emmett and Mary McDivitt purchased the property.〔 ==Exterior== This perfectly round structure has no central support system of timbers. With the exception of some timbers on the lower level, no structural member is more than thick. The main floor is raised above the surrounding ground, and the lower level, is at grade. The exterior is covered with vertical wood siding, painted white.〔 The lower level is made of studs about 2'6" on center. Joists span in various directions to make a platform for the second level. At this level the main drum has studs with rhythmically spaced angle bracing reaching to the upper first roof plate. These braces are paired and spaced and have intermediate stiffening diagonals. Each upper drum rests on a laminated sill/plate, which apparently acts as a tension ring.〔 An earthen ramp slopes up to the main entrance for the upper level on the west side. The doorway is in a projecting bay with a low gambrel roof. It has two sliding wooden doors consisting of three horizontal panels, with diagonally bracing in the top and bottom panels. At grade access is provided on the north side. Another pair of wooden doors once hung from the shed roof overhang, which has been removed.〔 The barn roof is a series of truncated cones. The cupola has a conical cap. The roof is covered in gray asphalt shingles. The overhanging eaves have exposed rafters and fascia.〔 Small windows provide light and ventilation on the main and lower floor. At the loft level, there are small, square, fixed windows around the building. In the cupola, square, louvered vents]] have replaced the windows, which were the same shape as those at the loft level.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thomas Ranck Round Barn」の詳細全文を読む スポンサード リンク
