"An explanation of the construction and action of the plain slide value, the piston value and the gears which operate them as applied to locomotives."
Here you get the details of valve gear used on railroad locomotives in 1917.
Chapters include locomotive valves and valve gears, the Stephenson valve gear, the Walschaert valve gear, effects of altering the valve and its events, locomotive valve setting, an appendix and so on. The fourth chapter discusses the Baker, Southern, Joy, Young, and Allen valve gear, and the Gooch stationary link.
Most valve gear books are loaded with geometric drawings teaching the design of the gear. Geometry is important, but this is somewhat different in that it is loaded with great views of locomotives, cross sections of valves and pistons, and detailed drawings of the gear. In other words, this isn't so much theory of design, as it is a handbook for locomotive shop men in keeping their engines running efficiently.
A reprint of a book written by practising locomotive engineers with the Pennsylvania Railroad.
