History
John R. Hart and James Hart, partners in the firm Hart Brothers, were in the business of mining and producing oil. They were the principal owners of the leaseholds of nine adjoining farms in Washington County, Pennsylvania. The other brothers, Guy Hart and Thomas Hart, were drilling oil wells contractors and, William C. Hart was a field superintendent. In the 1920s, 30s, and 40s, the patent applications were filed by William J. Hart, inventor from Hart Brothers & Co, regarding heating, cooling, insulating equipment for boreholes or wells, e.g. for use in permafrost zones.
