Thesis Abstract

Stop clocks are essential devices used in various fields such as sports, education, and scientific research to measure time accurately. Over time, these clocks may experience wear and tear, resulting in malfunctions or inaccurate timekeeping. This research project focuses on the repair of stop clocks to restore their functionality and accuracy. The repair process involves several steps, starting with a thorough assessment of the clock's condition. This assessment includes inspecting the internal components, checking for any visible damage or corrosion, and testing the clock's timekeeping accuracy. Once the issues are identified, the next step is to disassemble the clock carefully to access the internal mechanisms. During the disassembly process, special attention is paid to delicate components such as the escapement mechanism, balance wheel, and gear train. These components are often the source of common issues in stop clocks and require careful handling to prevent further damage. Any damaged or worn-out parts are then replaced with new components to ensure the clock's optimal functionality. After replacing the faulty parts, the clock is reassembled following the manufacturer's specifications and guidelines. It is crucial to pay attention to the alignment and synchronization of the internal components to ensure smooth operation. Once the clock is reassembled, it undergoes rigorous testing to evaluate its timekeeping accuracy and overall performance. In addition to repairing mechanical components, this project also explores the calibration and synchronization of stop clocks. Calibration is essential to ensure that the clock displays accurate time readings, especially in applications where precise timekeeping is crucial. Synchronization with external time references, such as atomic clocks or GPS signals, further enhances the clock's accuracy and reliability. Furthermore, the project investigates common issues that may affect stop clocks, such as magnetization, lubrication problems, and environmental factors. By addressing these issues during the repair process, the longevity and performance of the stop clocks can be significantly enhanced. In conclusion, the repair of stop clocks is a meticulous process that requires expertise, precision, and attention to detail. By following proper procedures for assessment, disassembly, repair, and calibration, stop clocks can be restored to their optimal functionality and accuracy. This research project provides valuable insights and guidelines for professionals and enthusiasts involved in the maintenance and repair of stop clocks.

Thesis Overview

INTRODUCTION

Time is the dimension of the physical universe, which at a given place orders the sequences of events. It is above designated instance in this sequence, such as the time of the day. Time measurement consists in counting the repetitions of any occurring phenomenon, and if the interval between successive recurrence is sensible, in sub-dividing it. A time interval may be measured in two epochs or simply by counting from an arbitrary starting point as is done with a stopwatch.

HISTORY OF TIME KEEPING

The clock (device used in measuring time) is one of the most influential discoveries in the history of western science. The division of time into regular predictable units is fundamental to the operation of society. Chronology dates back to 8th century BC, Heisod’s writing confirmed that during this period, celestial bodies were used to indicate agricultural cycles.

Later, the Greeks such as Archimedes developed complicated models of the heavens celestial spheres that illustrated the wanderings of the sun, moon and the plants against the fixed position of the stars.

In the middle ages (roughly 500 CE to 1500 CE) technological advancement virtually ceased in Europe. Sundial styles evolved, but didn’t move far from ancient Egyptian principles. During these times, simple dials placed above doorways were used to identify midday and four tide of the sunlit day.

In the first half of the 14th century large mechanical clocks began to appear in the towers of several large Italian cities. These clocks were weight driven and regulated by a verge – and foliot escapement. In 1656, Christian Huygens, a Dutdi Scientist, made the first pendulum clock, regulated by a mechanism with a “natural” period of oscillation. In 1671, William Clement began building clocks with the new “anchor” or “recoil” escapement, a substantial improvement over the verge because of its pendulum. There were other improvements made by various scientists on the clock over the last 300 years before we had the modern day clocks.

ESCAPEMENT

This is basically a medianism in which a toothed wheel engages alternate pallets attached to an oscillating member. The escapement is found principally in time pieces but may also be employed where never oscillating motion is required.

The escapement of a clock is the part of the clock that ensures accurate time keeping. Many escapements have been designed among the most successful are: the verge escapement, anchor escapement, deadbeat escapement, Grasshopper escapement, Electro-mechanical escapement; often-required in different clocks.

Some forms of escapements include true escapement, Runaway escapement, turned escapement and so on.
