Watt, James

1 Piece of brass tubing, with collar on

This item is part of the contents of the workshop that Scottish engineer James Watt developed at his home, Heathfield, at Handsworth, Birmingham. Although Watt is best known for his work on the steam engine, his workshop contains a wide variety of objects from many different projects, from chemistry to sculpture-copying.

The description of the item was written by Edward Collins, the land agent responsible for Heathfield when the workshop was given to the Science Museum in 1924. Collins could not always identify what he was looking at, but always described what he saw clearly. This has allowed his descriptions to form the basis of subsequent research.

This is a brass casting, turned overall, in the form of a short length of pipe, conical in the bore, with a broad flange near the narrower end. The bore is from 9/16 to 11/16 inch. The absence of fixing holes, or of any marks indicating use, suggest that it remains unfinished.
