Book Description
Excerpt from The Design of Valve Gears for Steam Engines It is assumed that the student is already familiar with the arrangement and operation of the simple steam engine having the plain slide valve. The purpose of this first chapter is mainly to review certain definitions, to bring out certain conceptions, and to give the symbols, abbreviations and letters of reference which will be used through the text, so as to ensure a common basis of under standing before proceeding with the development of the subject.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1907 edition. Excerpt: ...volume and diameter Of cylinder, the percentage of volume is less on long stroke engl11eg than on short. Wlith certain types of valve gear, as will be see" later, to prevent excessive compre$si0n large elearance is "acessary. 35. DRAWING HYPERBOLIC EXPANSION LINES. First Method. Start with the X and Y axes, Fig. 38, and using absolute pressures and volumes as co-ordinates, locate the point of cutoff, c, and draw the vertical line cc'. Through any point 1 in the line cp produced, draw Ol from the origin, to intersect ed at 2. Then the vertical and horizontal lines drawn respectively through 1 and 2, intersect at 3, which is a point on the expansion curve. Other points may be found in the same manner. Starting at k, the beginning of compression, draw the vertical line kk'. Through any point, 4, on this line, draw 04 from the origin to intersect the back pressure line kb at 5. Then the horizontal and vertical lines drawn respectively through 4 and 5, intersect at 6, which is a point on the compression line. The pressure at the end of compression _is found by first determining the point of intersection 7 between O0 and kl;/, and then from this point drawing horizontally to intersect the clearance line at 8. Second Method. To construct a hyperbola through the point b, Fig. 39, draw any line through this point to intersect the axes at a and a'. Along this line from a lay off a distance equal to ab, locating the point b', which is a point on the hyperbola. 36. CUSHIONING THE RECIPROCATING PARTS. First suppose there is no compression. Then when the pist011 9-pproaches the end of its stroke the effective steam pressure and the inertia of the reciprocating part are both acting towards that end of the stroke, ...

Book Description
Excerpt from Valve-Gears for Steam-Engines Graphical methods are used throughout, in the body of the book, both for demonstration of principles and for design of gear. In an appendix analytical demonstrations are given of certain principles that cannot be treated in a complete and satisfactory manner by construction only. Zenner's valve-diagram is used because it is widely and favorably known and appears to the author to be at least as good as any other circular diagram.
