Old Friend #123, the last motor-pump assembly made in the 1904 production year. A much lighter engine than #395, this engine probably proved to be too under-powered for the demands of greater pump pressures and better spray coverage.
The patent date on the pressure tank of Friend motor-pump #123 predates by one year the Company's production of its first prototype engine powered sprayer. The first Friend powered sprayers were hand pumps grafted to gasoline engines ... still a vast impr
Friend air-cooled engines show up in a variety of work environments in sales catalogs of 1908-1910. Grinding grain, sawing wood, chopping fodder . . . but the most unusual is that of a power unit on a New York Central and Hudson River Rail Raod service ca
Friend engine #395, an air-cooled model, exhibits holes in the side of the base for attaching the pump. Holes in the base beneath the rear of the cylinder attached jackshaft bearings to the engine. Early photos show engines complete with belt pulley on Fr
Made in very early 1908, engine #395 appears to be typical of Friend aircooled engines made in 1908 and 1909.
Pictured above is the engine and pump of an early Friend sprayer, possibly a rendering of the first experimental unit Friend made. According to Julia Hull Winter, sister to the inventors, the first engine used to power the prototype model was purchased on
