Description
Side view of a Whitworth Company measuring machine, capable of detecting variations in length to one millionth of an inch.
Figure 33 from the book The Whitworth measuring machine…, by T.M. Goodeve and C.P.B. Shelley (Longmans, Green & Co., London, 1877).
In the accompanying text, the authors state that: ‘It will be readily understood that the measuring machine, as constructed, is rather a machine for comparison than for simple measurement…The apparatus is to be regarded as a machine for measuring very minute differences in the length of bars specially prepared for end measurement. It is therefore peculiarly adapted for multiplying copies of standards of length.’

Sir Joseph Whitworth (1803–1887), British mechanical engineer and machine tool manufacturer, was elected a Fellow of the Royal Society in 1857.
