Synopsis

Patents For Inventions: Abridgments Of Specifications : Class. This volume is a historical English-language compilation of abridgments of patent specifications relating to agriculture, concentrating on Division I: Field Implements (including methods of tilling and irrigating land). It covers inventions from A.D. 1618 through 1866 and is designed to form a chronological, alphabetical, subject-matter, and reference index to the class in question, with prices for the full specifications noted where relevant. The preface explains that the indexes of patents have grown numerous and costly, and abridgments were published to provide accessible summaries that guide examination of the full specifications. The work lists a vast array of agricultural innovations, especially ploughs, drills, harrows, sowing machines, and related field mechanisms, many of which include improvements to existing tools, new forms of implements, and novel methods of applying seed, manure, or water to land. An extensive INDEX OF NAMES accompanies the text, enumerating numerous patentees. The volume is part of a multi-volume series intended to continue beyond the end of 1866 to cover later years, with the aim of aiding inventors and practitioners in locating relevant patent information. The text also reflects the material presented in the original Commissioners of Patents publication from London, including the serials and performances of various agricultural machines described across multiple entries.
