THE WAINWRIGHT HORIZONTAL FEED‐WATER HEATER.
We illustrate herewith the Wainwright Horizontal Feed‐Water Heater, adapted for use in a horizontal position under the floor of an engine room, or where the head room is limited. The feed water enters at the lower opening marked “feed,” fills the body of the heater, and having been heated by the exhaust steam surrounding the tubes, passes to the boiler at upper opening marked “feed,” the exhaust entering at either end. A drip pipe, as shown, is provided for escape of the water of condensation, and a hand hole for washing and cleaning. It will be seen that this heater contains a large body of water well disposed to receive heat, the tubes, being of corrugated copper, present 50 per cent. increased heating surface over plain tubes of the same length, while at the same time five times the strength is added, and owing to their property of expansion and contraction, all danger of the ends pulling out or the joints working and leaking is eliminated. This property of expansion and contraction also prevents any accumulation of scale and sediment.

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.
