. The Bee-keepers' review. Bee culture. General Description In design National Engines have all the strength needed to withstand con- tinuous hard work. Every working strain is properly provided for. The Cylinder is made of semi-steel, noted for its remarkable strength and density. Every hopper cooled cylinder is given a special high pressure water test to guard against leaks in the cylinder walls or jacket. The water space is exceptionally wide and a drain at the bottom of the cylinder allows water to be taken out when necessary. The Crank Shaft is a steel drop forging of the best quality, accrautely finished by grinding. The Connecting Rod is of malleable iron and has an automatic lubricating method. This takes care of the bear- ings on both ends from the waste cyl- inder oil—a saving of expense and trouble. The Piston is ground to a mirror finish and has automatic lubrication for the wrist pin bearing. The Piston Rings, three in number, are eccentiic and lap jointed. This is the most perfect ring known. They are ground like the piston. The Governor is of simplest design, hit and miss, absolutely reliable and economical in its regulation of fuel consumption according to load. The Fly Wheels—Smooth running in an engine, especially on truck, depends on the fly wheels. National Engines have lly wheels that are accurately Turned and properly balanced. The en- gines will run steady without blocking the truck wheels. The Mixer is our famous design with loth needle valve and air shutter reg- ulation. These adjustments enable the user to secure uniform results under varying loads. Lubrication is ample throughout—a sight feed oiler on the cylinder and automatic lubrication on the connecting lod. The crank bearings have hard oilers. Ignition is either make and break or jump spark. Each kind is of the simp- lest character and perfect in adjustment when the engine leaves the factory. National Engines are shipped ready to run after careful tests at the fac- tory. Unless
