The rocker beam pump was built onto a concrete foundation, which had slumped to the south, probably indicating subsidence of the ground around the adjacent shaft. The upper face of the foundation incorporated rebates for two wooden bearing beams, which were heavily rotted. The rocker beam itself comprises a horizontal timber extending from the axle to the top of the shaft as well as a vertical beam (the king post), which was strengthened with iron ties, and the two beams were connected by a further fixed iron tie. Power to the rocker beam (from the engine house) was provided via iron flat rods, the end of which attached to a bearing (the bishop's head) on the top of the vertical beam. Power was transferred to the pump via a further flat rod attached to the end of the horizontal beam. Other details: Figures 12, 22; photos 4, 7, 11.
