As an amateur clock repairer, I’ve been hunting for a good glossary of clock part names. Then one day I found clock conservator Matthew Read talked about one in his How to repair pendulum clocks – LIVESTREAM #005, where at about 1:26:00 he mentions a 17th or 18th Century work by William Derham. One of the live-stream attendees found the title of that work.

What follows is Chapter 1 of “The Artificial Clockmaker” by William Derham, published in 1734, courtesy of Google Books. This chapter gives the then-current names and descriptions of the parts of a mechanical clock. Many of these names have survived into the 21st Century. Where necessary I’ve added annotations in brackets.
