The Coal Viewer and Engine Builder's Companion / John Curr of Sheffield, agent to Duke of Norfolk, 1795. [Ms. of printed 1797 volume. Curr was agent to the Duke of Norfolk, being viewer of two of the Duke's mines near Sheffield. The volume is 143p. and contains 5 hand-drawn, hand-coloured plates. (Not all the plates are identical to the monochrome plates of the printed 1797 edition.) This ms. volume led to the earliest known printed account of an iron railway, giving details of iron plates, sleepers and points, and the wagons running on them, and detailed instructions on how to manufacture them. It describes the various kinds of 'jinney' used at pits to wind laden wagons to the surface. The major part of the work is an illustrated account of the steam engines used instead of 'jinneys' to pump water or to raise wagons, giving detailed specifications, tables of proportions and estimates of costs]
