Arthur H. Yocum and his father George Y. Yocum began building gasoline engines and small Speed-Well runabouts in Reading, Pennsylvania, in 1904. Isaac Hollenbach and J. S. Hornberger joined them in 1907, creating H. Yocum & Co., which employed about twenty people. Yocum built engines and completed cars using frames, bodies and transmissions supplied by several regional firms; its two- and three-cylinder engines also powered Eureka and Kearns motor buggies. An overambitious 1909 plan for an Oakland factory and 10–40 hp sleeve-valve cars collapsed, ending production. The qualifier distinguishes this marque from unrelated Speedwell manufacturers.
