Forney and Georg Kosak is a technical manual written in the late 19th century. It presents a clear, catechism-style guide to the principles, construction, and operation of steam locomotives for railroad personnel, mechanics, students, and interested readers. Expect plain language, abundant diagrams, and practical calculations covering thermodynamics, boilers, engines, valve gear, performance, and safety. The opening of the work sets out transcriber notes, plates, and publishing details, then a preface explaining how a German catechism by Kosak inspired a translation that Forney ultimately rewrote into an American-focused handbook, with acknowledgments and a defense of the “catechism” title. The introduction defines the broad audience and the commitment to simple explanations, briefly teaching the algebraic symbols and drawing conventions used. The text then begins its Q&A: it explains the basic steam engine (cylinder, piston, slide-valve, eccentric, rocker, flywheel), the forces of air and steam (atmospheric pressure, boiling point, saturated vs. superheated steam, absolute vs. effective pressure, expansion laws), and the ideas of work, energy, and the mechanical equivalent of heat. It introduces indicator diagrams to read cylinder pressures, and develops slide-valve action through motion-curves, lead, lap, travel, release, and the effects of connecting-rod angularity. Finally, it starts the topic of expansive working of steam, showing how to compute mean pressure and why cutting off early saves fuel, touching on wire-drawing and the comparative economy of different cutoff points.
