The Charter Gas and Gasoline Engine.
This gas engine, manufactured by the Williams & Orton Manufacturing Company, of Sterling, Illinois, possesses various features that must commend it to the attention of all interested in the production of power from gas. It is characterized by great simplicity, having no gearing, so that it is practically noiseless. It has a power and a supply cylinder, one placed over the other, and each working or worked by its own crank. An impulse is given at every revolution of the wheel, and by the governing device the amount of gas consumed is regulated in proportion to the work done. The ignition valve is easily accessible, and needs no adjustment on starting the engine. It can be used either for gas or gasoline. For the latter, a few drops are aspirated at each stroke into the cylinder, where mingling with the air they form the mixture for ignition. The gasoline can be kept in a tank outside the building, and is subjected to no contact with the flame until it has been thoroughly vaporized and has entered the working cylinder.
