  • Patent number: 4671126
    Abstract: The walking beam of a pumping unit is suspended from an oscillating hanger arm. It is pivoted at one end to a crank and to a link, the other end of the latter being pivoted to a fixed position shaft. At the other end of the walking beam is a point which follows a virtually rectilinear path between a bottom dead center position and a top dead center position. This point may therefore be coupled through a rigid member to an oil well pump sucker rod line.
