Section under construction

For some reason the early North winder sat well back in the engine-house, with the cylinders partly in the South and the drum only just inside the North. The overcast rope exited through a raised structure part way along the ridge of the  engine-house roof.

In 1904-5 this winder was replaced and the new one was positioned in front of it with the drum close to the end wall.  In order to accommodate to accommodate both underlap and overlap ropes, the  end wall was again reconstructed, with  the curved coping stone at the ridge now being replaced by two inclined slabs.

The ridge tiles and the slates also look to be new in comparison with those on the South engine-house roof .

The two side walls of the North engine-house appear to largely original. The lime-mortar is of a creamy-yellow colour  and and was probably produced from the local magnesian limestone bedrock since the 1875 1:2500 map shows a quarry and lime-kilns close by.  There is some indication that repointing may have taken place, but the mortar of the rubble core is of a similar type.  Later alterations and repairs are clearly distinguishable by the presence of a dark, crushed-shale mortar.

The lower sections on the outside of the North engine-house side walls are concealed by the in-filling of the boiler-houses with demolition material.  There are a few features that can be seen above ground however.

On the east side wall is an old steam pipe entry with a rim formed from curved stone segments. This was discontinued at some time and filled in with bricks.

About 3ft / 1m above the pipe-entry is a series of angle-irons embedded in the wall.  These appear to have been inserted when the wall was built and could have formed a support for the roof which is shown covering the boiler-houses in the 1885 etching.

At a similar height in the west wall is a series of corbel stones built into the wall. These could have formed a support for a roof similar to that on the east side or they could have been added later to support a gantry linking the two pit-tops when the South pit was upgraded to coal winding.
