Book excerpt: Excerpt from Valves, Valve-Gears and Valve Diagrams About eight years ago the author prepared a set of Notes on this subject and they have since been regularly issued and revised every one or two years in neostyle form. This method of issuing notes is admirable for the purpose of making revisions that appear to be desirable after a course in the class room, and the author would be reluctant to abandon this advantage were it not that the well-established points of the subject in general appear to be in such shape that very little revision has seemed necessary the past few years. On account of the fact that about twenty per cent. of new material, both in text and illustrations, has been added this summer in the preparation for this book, the author feels that there may be some revision of this new matter desirable after it has been tried out in the class room, and has, therefore, decided to publish the book privately and in small editions until, at least, this new part of the subject shall become as settled as the older part. A further prompting for issuing these notes in book form is the fact that during the past few years there has been a small scattered call from graduates who have not kept or have lost their loose-sheet notes, and also a call from outsiders. Books are more satisfactory in meeting such cases. Notes on this subject at Stevens Institute were started by Professor Jacobus, and continued by Professors Anderson and Pryor, until the subject came into the writer's hands in 1903. The work thus started was part of a more general course in engine work and consisted principally of notes leading up to the drafting-room course, covering eight problems which are now given at pages 17, 28, 50, 54, 64, 82, 98 and 116. Of these problems, four, comprising the double-ported, Meyer, Corliss and floating valves, have been either largely revised or entirely changed. The material in this book, aside from the drafting-room problems, has been arranged for classroom and recitation work after extended visits to drafting rooms in which the work in the design of valves and valve gears was being carried on in a practical way, and it is believed that the methods here presented will be found to agree fairly well with general practice. While an arrangement of material that would best fit in with the general course of mechanical engineering at Stevens Institute has been the principal aim of the author in presenting this work, and while many suggestions from numerous sources, including the works of Zeuner, Bilgram, Auchincloss, Welch, Halsey, Peabody, Spangler and Begtrup, have been adopted, there have been introduced some features that have been original in their conception so far as is known to the writer.
