Book Description
Excerpt from Slide Valve Gears: An Explanation of the Action and Construction of Plain and Cut-Off Slide Valves This work has been prepared to meet what the author considers a real want. It has been written with the aim of making it intelligible to any one who might be willing to make a serious effort to understand it. High authority exists for a mathematical treatment of the subject, but with this the author has no sympathy. Designing a valve gear is essentially a drawing board process, and a mathematical treatment of it is simply an uncalled for use of heavy artillery. The graphical treatment is therefore adopted throughout. Acknowledgment is due to Mr. Hugo Bilgram for his courtesy in kindly permitting the use of his valve diagram. The author has all due respect for the Zeuner diagram, but that respect is not incompatible with the conviction that Mr. Bilgram's method is a marked improvement upon it. Valve diagrams are used for two purposes - to analyze existing valve motions and to design new ones. The Zeuner diagram fulfils the first purpose perfectly, but is unsatisfactory when applied to the second. The leading data that are given in designing a valve motion are the point of cut-off, the port opening, and the lead of the valve (not the lead angle of the crank, as is often conveniently assumed).

Book Description
Excerpt from Slide Valve Gears: An Explanation of the Action and Construction of Plain and Cut-Off Slide Valves The irregularities due to the connecting rod introduce peculiar difficulties into the study of the first principles of the slide valve, which difficulties were first overcome by the happy expedient of using the slotted cross-head instead of the connecting rod in the preliminary study. For this, together with many other original and highly valuable contributions to the subject, we are indebted to Mr. W. S. Auchincloss, who first published them in his well-known and standard work entitled Link and Valve Motions, to which those who wish to prosecute their studies beyond the scope of this work are referred. The author has gone more fully than is customary into the methods of equalizing the various events of the stroke. The sections relating to these methods will be found more difficult to follow than the others, while at the same time they form no necessary part of a general treatment of the subject. Those who be gin their studies of valve motions with this book, may find these chapters too difficult for the first reading. They have, therefore, been marked with a star in the Table of Contents and in the body of the book, in order that they may be omitted, if desired, in the first reading; and it should be understood that the chapters not so marked form of themselves a complete connected trea tise, of a more elementary character than the book as a whole.
