Patents For Inventions: Abridgments Of Specifications by the Patent office is a historical reference compiled by the Patent office, presenting abridgments of patent specifications related to toys, games, and exercises from 1672 to 1866, published by order of the Commissioners of Patents and printed in London. This edition reissues the 19th-century text, preserving prefatory material such as a long Introduction tracing the antiquity of toys and a Preface by B. Woodcroft, along with an index of names and a descriptive index. The volume surveys a wide range of inventions—mechanical devices for playthings, educational apparatus, and toys used to teach or amuse—covering early table games, dice, kaleidoscopes, toy pistols, skating apparatus, and many other contrivances. Each entry records the inventor, the date, and the patent class, illustrating how the patent system organized innovations in amusement and education. Overall, it serves as a crucial historical record of nineteenth-century patent activity in toys and instructional devices.
