[8] In some instances, the heat from the fire contribute to faster deterioration in mantel clocks. [9] Clocks, regardless of the materials they are made of, are susceptible to damage from incorrect temperatures. Like light, temperature that is too high can cause weakening, discoloration, and or disintegration of organic materials. [16]
His clocks of the period used a grasshopper escapement which malfunctioned if not driven continuously—even while the clock was being wound. In essence, the maintaining power consists of a disc between the driving drum of the clock and the great wheel. The drum drives the disc, and a spring attached to the disc drives the great wheel.
In many clocks, the outer end is attached to a stationary post. The spring is wound up by turning the arbor, and after winding its force turns the arbor the other way to run the clock. The disadvantage of this open spring arrangement is that while the mainspring is being wound, its drive force is removed from the clock movement, so the clock ...

The gravity remontoire was invented by Swiss clockmaker Jost Bürgi around 1595. Usually the "Kalenderuhr" (three month running, springdriven, calendar-desk-clock) Bürgi is considered the oldest surviving clock with a remontoire, even if it does not provide power to the escapement during the few seconds of the daily cycle where the remontoire weight gets wound up by the spring.

Jaeger-LeCoultre's Atmos clock on display. Atmos is the brand name of a mechanical torsion pendulum clock manufactured by Jaeger-LeCoultre in Switzerland. The clock gets the energy it needs to run from temperature changes in the environment and does not need to be wound manually. It can run for years without human intervention.
American clock manufacturers produced similar looking cases made of iron or wood, known as "Black Mantel Clocks", which were popular from 1880 to 1931. [1] Seth Thomas Clock Company purchased the right to use the adamantine veneer in 1881, which they called Marbaline. [1] Their "Adamantine" black mantel clocks were made starting in 1882. [1]
In 1961, 19-year-old Robert Allen Zimmerman dropped out of college in his native Minnesota, made a pilgrimage to New York City to meet his folk music idol Woody Guthrie, and decided to become, in ...
