Measured Drawings of Betz’s Mill and Bahr’s Water Wheel

Heritage 4The portfolio contains 15 individual sheets of measured drawings to the specifications of the Historic American Engineering Record, Department of the Interior, reduced to 8 1/2 by 11-inch format. Nine sheets record the now-destroyed log construction circa 1770 Betz’s Mill of Lehigh County, Pennsylvania, and its “wooden age” grain milling machinery. Six sheets record every construction detail of the still-existing 1897 millwright-built 14-foot diameter wood overshot water wheel at Bahr’s Mill in Gabelsville, Berks County, Pennsylvania. The wheel is built to millwright Thomas Ellicott’s description in Oliver Evans’ book, “The Young Mill-Wright and Miller’s Guide,” 1795.
