The Story

My 3D printed history of clocks

Antic Clocks

Verge and Foliot

The Verge and Foliot is the first known mechanical clock and was invented in the late 13th century

There is usualy only an hour hand, the verge and foliot was not very precise, it is not uncommon to have up to an hour of variation per day

Galileo Escapement

A pendulum to regulate a clock

Galileo Galilei (1564 – 1642) is the first to have the idea of using a pendulum to improve the accuracy of clocks

The last year of his life, he explained his idea to Vincenzo Viviani, and this drawing made it to posterity

Grasshopper Escapement

Twin Pivot Grasshopper escapement

John Harrison (1693 – 24 March 1776)

https://en.wikipedia.org/wiki/John_Harrison

He invented this escapement around 1722 as an attempt to improve the accuracy of time keeping

He made multiple attempt to solve the longitude at sea issue

After trying with clocks, he built a watch that went on its first trial at sea on 1762 

The longitude prize was finally awarded to him in 1773

Meanwhile he continued to engineer regulators clock and claimed that his clock will be as precise as within 1 sec for 3 month. He died before he could finish 

A modern replica has proved that he might have been right, The full story is in this book:

Harrison Decoded: Towards A Perfect Pendulum Clock

Anchor Escapements Clocks

Recoil Escapement Clock

The First Clock

Feature a recoil escapement anchor invented around 1657

The frame is modular and need a support. It is one of my first design and is an easy clock to get started

Graham Escapement or Dead Beat Escapement

Clock One

Feature the Graham or dead beat escapement invented in 1675 by Richard Towneley

It is very similar to the clock above, parts can be mixed or shared, it adds a small second dial

It is another easy clock to get started

Watch Movements

Swiss Lever Escapement

Close up of the escapement

Invented between 1750 and 1800, it is now the most common escapement used in watches

https://en.wikipedia.org/wiki/Lever_escapement

This simplified movement will run for 6 to 8 hours

The 3 positions crown will rewind the main spring and allow to set the time

The beat is 0,666 second or 5400 BPH

Roskopf watch

Runs for 6 to 8 hours

The beat is 0,4 second or 9000 BPH

Hand made spiral sprind made with 0.4 mm piano wire

Georges Frederic Roskopf (1813 – 1889)

https://en.wikipedia.org/wiki/Georges_Frederic_Roskopf

He designed a watch for the proleterian, one that his workers could afford
