Project Abstract

Abstract
Stop clocks are essential timekeeping devices used in various settings, including sports events, classrooms, laboratories, and workplaces. Over time, these clocks may experience wear and tear, leading to malfunctions and inaccuracies in timekeeping. The repair of stop clocks is a specialized task that requires a systematic approach to diagnose and fix the issues effectively. This research project focuses on the repair of stop clocks, aiming to provide a comprehensive guide for technicians and individuals tasked with maintaining these timepieces. The study begins by outlining the common problems observed in stop clocks, such as erratic timekeeping, unresponsive buttons, and display malfunctions. By understanding these issues, repair technicians can efficiently troubleshoot and identify the root causes of the problems. The repair process involves a step-by-step methodology that includes disassembly, inspection, cleaning, repair or replacement of components, reassembly, and calibration. Each step is crucial in ensuring that the stop clock functions accurately and reliably after the repair. Special attention is given to delicate components such as the movement mechanism, buttons, and display screens to prevent damage during the repair process. Furthermore, the research explores the tools and equipment required for stop clock repair, emphasizing the importance of using the right tools for specific tasks. For instance, precision screwdrivers, tweezers, and cleaning solutions are essential for disassembling and cleaning intricate parts of the stop clock. Additionally, calibration tools such as oscilloscopes and frequency counters are employed to adjust the timekeeping accuracy of the clock. In addition to the technical aspects of stop clock repair, this project also addresses the importance of preventive maintenance to extend the longevity of these timepieces. Regular cleaning, lubrication of moving parts, and periodic calibration checks are recommended to prevent major malfunctions and ensure optimal performance of stop clocks. Overall, this research project provides a valuable resource for technicians and individuals involved in the repair and maintenance of stop clocks. By following the systematic repair process outlined in this study and implementing preventive maintenance measures, stop clocks can be restored to their optimal functioning state, allowing for accurate timekeeping in various environments.

Project 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.
