Mechanical Clock

Throughout history, there were many clock designs, their origins and original designers aren't very clear. Around the 13th and 14th century, the Mechanical Clocks slowly started to show up more. The early clocks were very simplistic and just chimed the hours. The early clocks were found in churches because of how heavy they were due to being worked by weights. The early clocks weren't very accurate until 1657 when Christiaan Huygens introduced the pendulum. The pendulum was far more accurate but the still used the sundial to set the clock. Christiaan Huygens is the one given the most credit for the making and evolution of the clock.

The later Mechanical Clocks worked using gears. They have two main parts: the mainspring and a pendulum. Mechanical Clocks are wound with a key, which tightens the mainspring. As the mainspring unwound, it turned gears which cause the hands to move. The pendulum keeps time and makes sure that the gears move at the right pace. Instead of a mainspring, some mechanical clocks had weights that pull the gears at the right pace. The energy created by the springs and weights made the Mechanical Clock work.

The Mechanical Clock started out very simplistic. It didn't have a face or hands and it just chimed every hour. It changed and added facing and hands as well as either a mainspring, gears, and a pendulum or weights and gears. As the Mechanical Clock change, it got more and more accurate. The purpose of the mechanical clock hasn't changed. It's always been to tell time.
