Change Gear Devices: Showing the Development of the Screw Cutting Lathe and the Methods of Obtaining Various Pitches of Threads (Classic Reprint) - Softcover
Inhaltsangabe
Change Gear Devices reveals how the screw-cutting lathe evolved through a century of change gears, with clear diagrams and practical insights.
This concise reference traces the development of change gear devices for engine lathes and explains how different gears create varying thread pitches. The book surveys numerous patents, weighs their practical value, and highlights the core ideas behind each approach. It is written to help designers, manufacturers, and shop professionals understand where these devices came from and how they work in real machines.
Readers will gain a practical overview of the methods used to obtain various thread pitches, from early concepts to more refined systems. The discussion emphasizes what makes a device useful in a workaday shop, not just in theory, with attention to ease of use, reliability, and potential commercial value.
- Clear explanations of the “cone of gears” and multiplying gear concepts guiding pitch changes
- Comparisons of major patents and the evolution of practical change-gear arrangements
- Insights into design trade-offs, practicality, and what matters in a machine shop
- A historical perspective on how lathes became capable of precise, varied threading
Ideal for readers of engineering history, machine shop professionals, and students seeking a grounded view of screw-cutting gear systems.

Paperback. Zustand: New. Print on Demand. This book explores the fascinating evolution of change gears for engine lathes, a key component in the development of precision machining. Tracing the history of the lathe from its ancient origins to the turn of the 20th century, the author delves into the ingenuity of mechanics who sought to improve thread cutting accuracy and efficiency. The book meticulously examines over 160 patents, highlighting the key innovations that shaped the field and revealing the intricate interplay between practical design and theoretical concepts. From the rudimentary lathes powered by treadles and cords to the more sophisticated machines driven by belts and gears, the book chronicles the gradual shift from manual to mechanized thread cutting. The author highlights the importance of early patents, such as Bancroft and Sellers' 1854 invention, which laid the groundwork for the development of change gear systems. The text further explores the innovations of John Humphreys, Frederick B. Miles, and William Bley, among others, and their contributions to the refinement of change gear mechanisms. The book offers a fascinating glimpse into the world of mechanical invention and the relentless pursuit of innovation by the men who shaped the modern machine shop. The author's detailed analysis of patents and the insightful commentary on their strengths and limitations provide a valuable resource for anyone interested in the history of manufacturing and the evolution of essential machine tools.
