MERY "EXPLOSIVE" ENGINE -- 1/4 Scale
The Mery "Explosive" Engine was a very unique design, originating from the machine shop and foundry of Mr. Michael Mery back in 1895. Located in Chico, CA, Mr. Mery patented his design around the main idea that it was best to completely purge the combustion chambers with clean air in between each charge and firing. It was on this premise that he added a 5th and 6th stroke to the newly established 4 stroke design in order to accomplish the task of purging the engine. Another unique feature of Mr. Mery's design, was to incorporate the "double acting" design already existing in most steam engines of the day, whereby both sides of the piston were used to produce power. To do this, Mr. Mery used the steam engine design of a crosshead between the connecting rod and piston. This allows the shaft to the piston to be sealed using a compressed packing or "Stuffing Box", creating the ability to have a second combustion chamber on the bottom side of the piston.

GADE BROS. 1½ HP ENGINE -- 1/4 Scale
Gade Bros. Manufacturing Co. started business in 1903 and produced some of the first reliable, air cooled, gasoline powered engines for farm use. In 1912 they introduced a small 1½ hp engine, the Model "C", suitable for "small" farms. It was said by proponents: "The Gade engine uses at least thirty-three and one-third per cent. less gasoline than any other make engine. On account of the few parts and extreme simplicity, it costs practically nothing to operate this engine. It will start quickly in cold weather, whereas a water-cooled engine will not." The company also guaranteed all parts "free from defects in materials or workmanship" for five years from the date of purchase.

JOHN DEERE 1½ HP ENGINE -- 3/10 Scale
Deere & Company purchased the Waterloo Gasoline Engine Company in March of 1918 and for eight years continued to manufacture Waterloo Boy Gasoline engines at Waterloo, Iowa. In 1923 they introduced the John Deere Model "E" gasoline engine. This engine was manufactured in 3 sizes (1-1/2, 3, and 6 Horsepower) until 1946 with very few and very minor changes in the design of the engine.
The smallest and most numerous of the Model "E" is the 1-1/2 HP, with a 3" bore and a 4" stroke. Most of these engines used hit and miss ignition, an igniter, and a low tension magneto ... only a few used a spark plug, battery and coil. The head is a "dry" head with the fuel mixer cast as a part of the head. The gasoline tank is mounted below the flat oil pan and between the skids. The engine features an enclosed crankcase. Oiling of the engine is accomplished with an oil cup mounted on the oil pan. The balls of the governor rotate inside this cup of oil and splash oil to all parts of the engine. There is no crankcase ventilation.
