Brass tubing, in brass screwed cup

Watt, James

1 Piece of brass tubing, in brass screwed cup

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 item comprises two pieces of brass, screwed together: a piece of thick-walled brass tube, perhaps made by drilling a rod, is reduced and screwed at each end. One end is screwed into a hole in the side of a cylindrical brass casting that has been partly turned, bored from one end and screwed internally with a coarse thread, so that the tube communicates with this cavity. Perhaps this component was intended for some experiment in the use of steam.
