Porter, Dot, "Facsimile of LJS 163, Allgemeine Maschinenlehre nach den Vorfrägen des Herrn Professor Dr. Rühlmann" (2015). Schoenberg Institute for Manuscript Studies (SIMS): EBooks. 230.
Drawings of machines, grouped by type, such as sewing machines, presses, scales, water wheels, turbines, cranes, steam engines, and locomotives, arranged to illustrate the development of the machines and accompanied by historical notes which often refer to the inventor and give citations to works dated as late as 1864, made while the author was a student at the Polytechnic Institute in Hannover, now Leibniz UniversitaÌˆt Hannover. The title page refers to the VorfraÌˆgen (Preliminary questions) of Dr. RuÌˆhlmann, probably the 4-volume encyclopedia of mechanical engineering titled Allgemeine Maschinenlehre, published by Christian Moritz RuÌˆhlmann, professor of mechanical engineering at Chemnitz; the first volume was published in 1862. A printed table concerning the performance of various locomotives, with a reference to an exhibition of 1862, is bound in near the end of the manuscript (f. 195) and folds out.
