Novelties of Construction

By GARDNER D. HISCOX, M. E.

Octavo, 396 Pages, 970 Illustrations. Price, $2.50.

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.
