This new title is a thoroughly documented and researched book about the history of the designs of antique barbed fencing. This book describes hundreds of patents and more than 2,000 patent design variations found in antique barbed fencing. Varieties include mild steel barbed wire strands, sheet metal barbed strips, barbed metal rods, and barbed wooden rails. Antique barbed fencing evolved from the wooden fences and plain wire fences of the 1850s. The major antique barbed fencing period occurred from the late 1860s and mid-1870s to the early 1900s, when inventors in the Midwest and Northeast designed hundreds of new ways to corral livestock. Using U.S. Patent and Trademark Office records and other information sources, author James R. Newman describes how the inventors considered their patent designs unique, what their purpose was, and what factors influenced the changes in these designs over time. Newman describes the common patterns found in the structure and form of these patent designs. Because of the complexity in these designs, he provides a proposed classification system that can be used for sorting, organizing, and indexing barbed fencing patents into similar patents and design groups. This book is intended for collectors, farm historians, and anyone who has ripped their pants crossing barbed wire fences.
