Biographical

James Leffel was born in 1806 in Botetourt County, Virginia to John and Catherine Leffel. The family moved to Ohio, settling near Springfield. where John Leffel established saw and grist mills. Leffel grew up surrounded by mills and and developed a strong interest in water wheels. Leffel trained as a millwright acquiring skills in metal work to make sickles, knives, and other small iron implements. In the late 1830s, Leffel established his first foundry and machine shop near Springfield, Ohio, quickly expanding and taking on two partners, William A. John and T.Y. Ferrell and adding mill gearing and stoves to their line of products. By 1845, Leffel ended his business relationship with John and Ferrell and formed a partnership with William Blackeney, a machinist who helped him support the foundry and its work. In 1846, Andrew Richards joined Leffel to build a cotton mill and machine shop. Leffel envisioned the utilization of water power in Springfield. Ohio, with the establishment of mills along a race--a dug channel leading from a creek or river to the mill--that would eventually bring trade. With the help of Samuel and James Barnett, gristmill operators, Leffel was able to "cut a race" and erect a Water Power and Flouring Mill. Leffel was especially interested in water wheel development and would receive patent US34,150 for a water wheel (1862) which later reissued as RE1791 and RE1792 in 1864.

Leffel also patented cooking stoves (US6775) in 1849 which became known as the "Buckeye," "Double Oven" and "Red Cook Stove" that were successful and earned him a strong reputation. In 1852, Leffel broke with Richards, and Nathaniel Cook, a machinist, joined Leffel and Blackeney. With his 1862 patent for a water wheel, Leffel focused his attention on demonstrating the water wheel and speaking about its productive uses. Numerous test runs of the water wheel convinced Leffel that he could sell the wheel to mills and factory operators. Leffel marketed the wheel as the "American Double Turbine" an efficient, cheap turbine for the mass market (Layton page 86 ). In 1863, Leffel and Blackeney formed a new firm, along with Perry Betchel and Leander Mudge to create a foundry designed solely for the production of the wheel. Leffel later joined forces with John Foos, a mill operator and James S. Goode, a lawyer, to form the James Leffel and Company. Leffel sold his water wheel to flour mills, woolen goods manufacturers, paper mills and farm equipment manufacturers. The company became one of the leading manufacturers of waterwheels and turbines and today continues to operate under the name of James Leffel and Company as part of Canyon Hydro which acquired the company in 2019.

Leffel died in 1866.
