Humphreys mine and associated coke ovens and patch town, in Unity Twp. of Westmoreland County, was opened in the late 1800s by the Bessemer Coke Co. of Pittsburgh. Later operators were Hecla Coal and Coke Co., and Humphreys Coal and Coke Co. As late as 1956 Humphreys-Connellsville Coke Co. was reporting 145 machine-drawn coke ovens still in use at Humphreys. Although the Humphreys No. 1 and No. 2 coal mines were depleted by then, closing in 1946, so they must have been coking coal from other mines. At first there were only beehive coke ovens at Humphreys, but later Bessemer Coke added rectangular ovens, similar to the rectangular ovens that they installed at Griffin in Fayette County. This was one of the coal and coke operations in the Connellsville Field that was never purchased by H.C. Frick Coke.
