Description
Plan and elevations of a Whitworth-manufactured flat plane surface for use in engineering workshops.
Figures 1-3 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: ‘The surface plate [exhibited at the Glasgow meeting of the British Association in 1840] …was made of cast iron, and consisted of a rectangular plane table, ribbed at the back, and resting on three bearing faces…Sir Joseph Whitworth has lately patented an hexagonal surface plate (see figs, 1, 2,and 3) with the view of preventing irregular straining, the points of attachment being identical with the points of support’.
Inscribed below: ‘Plan and elevations of Hexagonal Surface-plate.’
Sir Joseph Whitworth (1803–1887), British mechanical engineer and machine tool manufacturer, was elected a Fellow of the Royal Society in 1857.
