Mechanics in the Mechanical Clock

2. Introduction • The mechanics in a clock are not complex but just work in a system which is called the escapement.

3. Escapement • Escapement mechanics, a device that permits controlled motion, usually in steps. In a watch or clock, it is the mechanism that controls the transfer of energy from the power source to the counting mechanism. The classic form for a timepiece, which made the mechanical clock possible, was the verge escapement, probably invented in 13th-century Europe

4. Power Source • In mechanical clocks, this is either a weight suspended from a cord wrapped around a pulley, or a spiral spring called mainspring.

5. Oscillato • In mechanical clocks, this is either a pendulum or a balance wheel

6. Controller- it is not the same as escarpment! • In mechanical clocks, this is the escapement, which gives precise pushes to the swinging pendulum or balance wheel, and releases one gear tooth of the escape wheel at each swing, allowing all the clock's wheels to move forward a fixed amount with each swing.

7. Some Cool Facts • By the late 1300s, Europeans had mechanical clocks and often installed them in the towers of churches and town halls. • Mechanical clocks replaced the old water clocks, which, by the 13th century, had been a round for millennia. • The first clear drawing of an escapement (clock part)was given by Jacopo di Dondi and his son in 1364. round for millennia.

9. Conclusion In conclusion the mechanics in a clock have 3 main parts. The power source, the Oscillato, and the controlling center or the controller. And a mixture of all of these which work together to make a clock work is called the escarpment.
