Mmm. The cog and rung gin refers to the use of a horizontal drum.
The pit I am looking at would have been pretty crude although it operated for some years. The coal was destined mainly for lime kilns and had a very high tar content. (Thereby hangs a name...Tarry Colliery!) A nearby pit where there was a fatality in 1859 refers to that pit being about 24 ft. deep with tubs being brought to the surface by hand roller.
