It consists of eight metal bars, two 21.6 cm. long and six 11 cm. long. Holes in the bars and suitable pivot points allow one to alter the enlargement or reduction of the image. A pivot-post on the right side at the center (now missing) held the instrument to a drawing-board or table at the desired height. To enlarge drawings, once the bars were suitably set, a tracer-point was placed at the joint nearest the pivot-post. The drawing point was on the same line, at the joint furthest from the pivot-post. To reduce drawings, the tracer point and drawing point were reversed. No points survive."}, {"label": "Description", "content": "Lucien F. Bruce (1835-1910) and Newlan J.
