Machinery

This machine makes a uniform movement through a weight, a spring or a pile; This movement is regulated with a pendulum or steering wheel and is transmitted to the hands by means of different gear wheels .

History

Pendulum clocks were used in the towers of churches and castles in the 13th century and it was not until the 15th century that they began to be used for domestic use. Huygens Christian was the first to patent the pendulum clock in 1656 , which made it possible to measure time with greater precision. Huygens made some trips between 1662 and 1686 and from there he made some pendulum clocks to be able to measure the length in the sea . The pendulum clock was an invention that allowed time to be measured more precisely and was refined over time.

Functioning

The operation of this type of clocks is regulated by a pendulum. In them the driving force is the action of gravity that acts on a mass suspended from a rope wrapped around a cylinder . This cylinder transmits the movement to the pinion, which in turn moves the wheel. In the first clocks used at the top of the towers and bell towers of the towns and cities so that the citizens were aware of the time, a mechanism called exhaust was used with which energy is obtained from the descent of some weights and supplies it to the pendulum. The most widely used escapement in this type of watch is the Graham looper escapement .
