Brief Description of Patent: This invention relates to the valve gear of gas or other internal combustion engines working on what is known as the "Otto" cycle, and its object is to operate the necessary valves in an improved manner, preferably direct from the crankshaft, instead of from a sideshaft driven by gearing at half the speed of the engine as is now commonly done. 

Condition: Slight crinkling. Pages loose. Wear to left hand edge where patent has been removed from the volume. 

This was sold by a Library and has their stamp impression on some of the pages/drawings. Multiple Item Postage: Patents can be combined for postage costs, the cost is the same whether you purchase one or several, so check out our Ebay Shop patent listings as well. This patent specification has been disbound from a volume of 100 different patents. This is an original HMSO published item at the time, not a modern copy as are being sold elsewhere. The drawings are often ideal for framing. It is part of a collection of several volumes from the 1893-1900,1907 & 1920/50's that I have from which individual patents will be sold over the next few years.
