Author: CLARK, WILLIAM, PATENT SOLICITOR
Title: Clark's Table of Mechanical Motions
Description: 53, Chancery Lane, London, Mr. W. Clark, Patent Agent. 1852, First [& only Edition?]. Chart 420mm x 335mm tall approx. with 106 steel-engravings by G.H. Keeling. On the verso are printed descriptions of each movement and Mr Clark's advertisement. The Author, who is described variously as Agent, Solicitor and Engineer, produced the chart at, or shortly after British Patent Law was modernised in 1852, when setting himself up as a Patent Agent. He comments - "The idea of a Table of Mechanical Motions presented itself to me as likely to be useful to inventors in recalling to mind a movement that may be required as link in some mechanical combination, or as suggestive of improvement.", and his advert sets out the cogent parts of the new law, together with a note of his charging structure. The footnote - "Cheques or Drafts to be crossed 'Union Bank' " - has been amended by a contemporary hand, to read 'London & County'. A little dust dusty along some folds and with some joints, cracked without loss, neatly repaired on the verso with transparent archival tape. The chart is multi-folded and retained in the original maroon cloth-covered, thin card covers/gilt title, to form a booklet of approx. 110mm x 175mm tall. Free corners of the covers worn, but overall a good example of a scarce item from an important period in the history of invention and commerce.
