Catalogue description

Science Museum Group description

This large wheel engine was used to cut the teeth on the edge of clock and watch wheels. This is the earliest known dated tool from Lancashire, the centre of the manufacture of English horological tools during the 1700s.

Historical context

Precision & Scientific Horology (1750 – 1850)

Harrison solves longitude; Mudge invents the lever; Breguet's Paris workshop defines the modern watch.

The age of the deadbeat escapement, compensated pendulums and observatory regulators. Domestic clocks spread through the middle classes: English longcase and bracket clocks, French gilt-bronze mantel clocks, Viennese Biedermeier wall clocks, Black Forest painted-shield clocks, and the first American shelf clocks.

Atlas type guide

Domestic clocks

A clock combines four systems: a source of power (falling weight, coiled spring, or later electricity), a gear train that divides time, an escapement and oscillator that regulate it (foliot, pendulum or balance), and an indicating system of dial and hands or a bell. Its history runs from the large iron weight-driven clocks of the late thirteenth century to Renaissance spring-driven table clocks, the pendulum revolution of 1656, the factory clocks of the nineteenth century and electric and quartz clocks of the twentieth.

Domestic clocks also reflect regional furniture and decorative traditions — English longcase and bracket clocks, French pendules, Viennese regulators, Black Forest and American shelf clocks — and therefore record changing tastes as much as technical progress.

What to look for

  • How the clock is powered: weights, spring barrel, fusee, electric coil.
  • The oscillator: foliot, short pendulum, long seconds pendulum or balance.
  • Whether it strikes: hour only (count wheel) or hours and quarters (rack striking).
  • The maker or retailer's name on dial and movement, and any factory trademarks.
  • Signs of alteration — replaced dials, converted escapements, 'married' cases.

Dating clues

  • Before 1656 clocks used foliots or balances; after, most domestic clocks have pendulums.
  • Anchor escapements spread after c. 1670; minute hands became common at the same time.
  • Factory production in America and Germany transformed prices after c. 1840.
