IC Engines Vol. 2: Eighteen Unusual Engine Patents from 1880 through 1895

Towards the end of the 1800s the concept of the internal combustion engine was high on the list of things that needed to be invented. During this period a lot of rather strange looking designs were patented. This book is a reprint of eighteen patents issued between 1880 and 1895 by the United States Patent Office. Most of the designs probably never made it so far as to become a running engine. Some of the others have inventors whose names are still recognized, such as Gottlieb Daimler and Rudolf Diesel.
