A Treatise on the Teeth of Wheels
First published in the 1750s as part of his Cours de mathematique, this study of epicycloid gearing and the design of trains was one of the most significant advances in horology and mill work.
In 1806 it was translated into English by J.I. Hawkins and then reprinted in 1837 and 1868. The second edition, available here, has an extensive appendix which includes a survey of contemporary watchmakers undertaken to see who, if anyone, made timepieces with correctly formed gear teeth.
This copy of the book is based on the copy made available by Google Books (see Google Books copy of Camus). However, there are three important changes:
- Two plates (37 and 40) are missing from the Google Books copy. These have been inserted in this copy.
- Three plates (23, 26 and 27) were cropped when scanned for the Google Books copy. These have been replaced.
- The Google Books copy is complete, with scans of the covers (inside and out) and of all blank pages. I have omitted the covers and blank pages.
