As time passed, the Ohio Saxon barn incorporated modifications which enabled it to perform differing agricultural functions better. Additional aisles were added, accessed by smaller doors on the gable. If used primarily for crop storage and processing, the structure is usually termed the Transverse Frame barn, or sometimes the Midwest Three Portal barn. A threshing floor occupies the center and the other interior features of the Ohio Saxon barn are peripheral. The major difference from the Ohio Saxon barn is the orientation of the entryway. If used mostly for livestock, the structure is termed a Feeder barn, with a row of cow stanchions on either side of the central aisle. A connection with transverse frame barns brought into Ohio from Appalachia cannot be discounted (see Crib barns).
