Description
Study of an engineering shop worker using a scraping tool to manufacture a Whitworth flat plane surface.
Figure 8 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 method of holding the scraper will be apparent from fig.8. The workman takes the tool in his right hand, pressing its edge upon the surface to be scraped. With his left hand and at the same time moves the tool to and fro over a small space, thus taking off very small quantities of metal in the form of either minute shavings or fine powder, according to the degree of force exerted.’
Inscribed below: ‘Method of holding Scraping Tool.’
Sir Joseph Whitworth (1803–1887), British mechanical engineer and machine tool manufacturer, was elected a Fellow of the Royal Society in 1857.
