Arm for dividing apparatus built by James Watt

Made:
1772-1774
maker:
James Watt

An arm for the dividing apparatus built by James Watt, and preserved in his workshop. (see Table in centre of room)

This object is part of the contents of the workshop which belonged to Scottish engineer James Watt, best known for his work on the steam engine. It is an arm for the linear dividing apparatus also present in the workshop, which was used to produce the graduated linear scales used on scientific instruments such as barometers. the arm was apparently the second of three - the first lies on the desk to the left of the workshop window, while the third is fitted to the apparatus itself.

The workshop contents consist of a mixture of ongoing projects, in large part around sculpture and sculpture-copying which occupied Watt’s retirement years, and also items from Watt's working career stretching back to his early work as an instrument-maker in Glasgow.
