Flat round pieces of brass, three holes and short length of tubing on
2 Flat round pieces of brass, three holes and short length of tubing on, from James Watt's workshop
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. These are the swivel plates of furniture castors, and are likely to match up to the balls and handles recorded elsewhere in the workshop, used for making copies of large drawings too big to fit in the copying press developed by Watt. See the preceding entries for 'ball in iron frame with mahogany handle etc.
