Converted steam winch - top of Swannington incline

This is at the top of the Swannington Incline and appears to have been relocated here. It was once a double reduction geared twin cylinder steam winch. One disc crank has been replaced by a gear and there is a loose electric motor and chain guard that presumably went with it. The engine has Easton & Tattersall, Leeds cast in the bed - a maker I'm not familiar with. This was used at the Calcutta Pit pumping station nearby - SK4216 : Calcutta Pit pumping engine house. and presumably converted to electric drive when the huge steam pumping engine was decommissioned. This side shows the surviving disc crank and crankpin with a rectangular projection that would have engaged a slotted crank to operate the valve gear eccentrics. These latter were in the depression in the projection at the front of the bed that is flanked with the seating for two sets of bearings. Beyond this, the bed carries the lower half of the crosshead guides (4-bar type) and beyond that would have been one of the two steam cylinders. The flywheel has a band brake around its periphery.
