If you aspire to be an horologist, you don’t have to done fishnet stockings and hot pants, you merely need to study up on the design and manufacture of escapements. Luckily, there is a nifty illustrated book on the Project Gutenberg website that details some of what you’ll need to know: Watch and Clock Escapements, by Anonymous. If you haven’t thought of it before (and why would you, in this soul-less age of digital watches), how do you think that mechanical watches actually worked? Well, they use a gadget called an escapement, the design of which is the core function of traditional clockmaking. From the book:
The problem to be solved by means of the escapement has always been to govern, within limits precise and perfectly regular, if it be possible, the flow of the motive force; that means the procession of the wheel-work and, as a consequence, of the hands thereto attached. At first blush it seems as if a continually-moving governor, such as is in use on steam engines, for example, ought to fulfil the conditions, and attempts have accordingly been made upon this line with results which have proven entirely unsatisfactory.
Having thoroughly sifted the many varieties at hand, it has been finally determined that the only means known to provide the most regular flow of power consists in intermittently interrupting the procession of the wheel-work, and thereby gaining a periodically uniform movement. Whatever may be the system or kind of escapement employed, the functioning of the mechanism is characterized by the suspension, at regular intervals, of the rotation of the last wheel of the train and in transmitting to a regulator, be it a balance or a pendulum, the power sent into that wheel.
Interesting stuff.
Hey, cool! Someone noticed one of my books. 🙂 You may also want to look at Clocks, Watches, and Bells, by Lord Grimthorpe, of Big Ben fame (or infamy) which I scanned at the same time.
