Catalogue description

Description

A large rectangular clock and sign (2013.208.2a). The front and back of the clock has a stained glass sign that reads “CITIZENS / SAVINGS / BANK / & TRUST CO.” The clock is located under the stained glass sign on the clock's front. The body of the clock is constructed of copper metal. The sides of the clock are made of copper and have small vent-like patterns running from top to bottom. The back of the clock has an opening that reveals the inside electrical components of the clock.

Description

2013.208.2b is the base of the clock. The base is wood and rectangular in shape. The base has some cornice work at the top and bottom.

Description

2013.208.2c is a metal electronics box used to operate the clock. It has a black top and sides. On the front left is a metal switch indicating when the timer is on or off. On the front right is a red button for setting the clock. A red sticker with typed white letters above the button reads “PUSH TO SET CLOCK.” The back of the box has three holes where wires enter the box. The hole in the middle of the box has a label above it that reads “110 V .AC.” The other two holes are on the left side of the box. The left most hole has a label above it that reads “24 V. DC PLUS.” The other hole has a label that reads “24 V. DC MINUS.”

Description

2013.208.2d-k are frosted glass light bulbs that are oblong in shape. The top part of the bulb is wider than the neck, which enters a metal screw base. At the top of the bulb is a small Westinghouse logo within a circle, below which is the text “Eye Saving / 100 watt / 125V / USA.”

Historical context

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

Post-war clocks combined new materials and industrial design: plastic and metal cases, battery-powered transistor movements from the late 1950s, and design classics by George Nelson, Max Bill and others. The first caesium atomic clock (1955) moved the definition of time from astronomy to physics.

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.
