Moteur Mac Allen

Back in 1892, Gustav Richard published a three volume series on gas engine design. One volume is devoted to plates of various engines. We thought that the 'Moteur Mac Allen' of 1889 was quite a novel approach to charging the cylinder. The power cylinder is located above, with the charging cylinder situated beneath. By altering the volume of the charging cylinder, one could actually achieve some degree of supercharging with this design.

Another interesting design is the 1895 version of a duplex engine built by Compagnie Parisienne in France. This one uses an interesting combination of a sideshaft, plus a cross-mounted cam shaft. Note also the unusual arrangement of spur and bevel gears at the crankshaft. In case you're wondering why these 'foreign' engines are appearing here, we thought perhaps that the unusual designs might be the catalyst to move some of our model makers into action. Hopefully, we'll be hearing from somebody in the next few months or so, announcing that they have tackled one or both of these unique designs.

From the February 1911 issue of Gas Energy Magazine we read the following:

'Norton & Newland, Marshalltown, Iowa manufacturers of gasoline engines, windmills, pumps, etc. have sold out to Gauthun & Bratteig.

'Economic Engine Works, Utica, New York will occupy the Forry planing mill property at Columbia, Pa. on February 1, 1911. . . .The company builds gasoline engines.

'Evansville Manufacturing Company, Evansville, Wisconsin opened its doors January 2, 1911. Frank Frost and Chester Morgan are the managers, and the company will use the Grange warehouses as a factory. The firm will make a specialty of manufacturing gasoline engines, and will begin work on a one horsepower engine which Messrs. Frost and Morgan recently invented, intended for farm use.'
