. Bulletin - United States National Museum. Science. SIMPLEX GASOLINE AUTOMOBILE, 1912 Gift of Mr. and Mrs. John D. Adams in 1 929 (USNM 309549) This car (fig. 88), made by the Simplex Automobile Co., of New York City, represents one of the most powerful and popular automobiles of its day; it was capable of a speed of around 80 miles an hour. It was used until 1928 by the son of the donors. The water-cooled engine (figs. 89 and 90) is of the 4-cyl- inder, 4-cycle, T-head type, with cylinders cast in pairs. The bore and stroke are the same, 5% inches, giving a total piston displacement of 597 c

It was used until 1928 by the son of the donors. The water-cooled engine (figs. 89 and 90) is of the 4-cyl- inder, 4-cycle, T-head type, with cylinders cast in pairs. The bore and stroke are the same, 5% inches, giving a total piston displacement of 597 cubic inches. Each cylinder has an intake valve on the right side and an exhaust valve on the left, operated by two camshafts in the aluminum crankcase. The exhaust camshaft is movable lengthwise by means of linkage controlled by a handle reached from under the front of the radiator. Moving the camshaft lifts the exhaust valves partially from their seats, lowering the compression and aiding in starting with the hand crank. The exhaust manifold leads to a muffler under the left side of the car. Figure 88.—This 1912 chain-drive, 50-horsepower Simplex was reconditioned in 1949 through the courtesy of George C. Hane, of Washington, D. ,-?*" '.
