This book, while complete in itself, is in fact a supplement to the preceding volume. Unlike the first volume, which is more elementary in character, this volume contains illustrations and descriptions of many combinations of motion and of mechanical devices and appliances found in different lines of machinery. Each device is illustrated by a line drawing with a complete description, showing its working parts and the method of operation. The machines illustrated and described cover an immense field and have been carefully selected to supply the needs of those seeking either general or special information.
