With regard to Lankford and Taylor (1999), one of his candle clocks “included a dial to display the time and, for the first time, employed a bayonet fitting, a fastening mechanism still used in the modern times” (p.131). In 1206, Al-Jazari’s work had one of the exceptionally complicated candle timers. As time progressed, the design of the candle clocks became even more sophisticated. However, this issue was later to be less of a challenge since “the candles were placed in wooden framed glass, to prevent the flame from extinguishing” (Itano & Norman, 1999, 41). One of the challenges of the clock was that the candles could be extinguished once they were lit hence impairing the performance of the clock. The candles were consumed for close to four hours with each mark representing a 20-minute time erasure. Another important requirement for candles used to make the clock was that they were all required to be of uniform thickness. Each candle was 12 inches long calibrated at an interval of 1 inch. From an engineering perspective, the clock was made from six candles, which were composed of 72 pennyweights derived from wax. The most famous candle clock is related to King Alfred the great. A corresponding class of “candles were later to be used in Japan until early 10th century” (Itano & Norman, 1999). With regard to the poet, a calibrated candle was deployed to help people determine the time at night. Nevertheless, they were first mentioned in You Jinful poem written in Chinese language in 520. There exists a historic timeline gap for when the candle clocks were discovered and or used first. Such a technique was the development of candle clock. These limitations made provisions for the need to develop other techniques of times measuring in a more reliable manner. Hence, recalibration of the clock was necessary whenever such changes occurred. This requirement posed major challenges to the development of a more reliable clock sun was required to shine since for its operation.Ĭonsequently, the clock could not function at night or during cloudy weather conditions. Engineering designs deserve to be reliable over a wide range of variables. The sundials were deployed to scrutinize the operation of the clocks until early in the recent times. However, the time measured by the instruments was merely the solar time. This clock was widely used during ancient times since it would measure time with high degrees of accuracy. Sundial clocks were deployed to measure times through a shadow cast on a cylindrical stone. How the Clock developed over Early Years (1-1500 AD) in terms of Engineering Sundial Clocks In this light, the paper tracks changes in the operation mechanisms of the clock in the quest to provide theoretical records of evolution of engineering. The theoretical approaches deployed in the paper are from engineering paradigms. The purpose of this paper is to scrutinize the historic evolution of a clock. New engineering discoveries led to the emergence of new versions of clocks such as water clocks, candle clocks, pendulum clocks, incense clocks, and later clocks with escapements and gears followed by the most accurate clocks – atomic clocks. One of the earliest clocks was the sundials whose operation relied on the natural phenomena of different sizes of shadows cast on an object as times progress in a day. These modern versions of clocks are mainly mechanical clocks having either analogue or digital display formats. Indeed, “devices operating on several physical processes have been used over the millennia culminating into the modern version of clocks” (Jones, 2004, p.67). Over the process of evolution in the engineering of a clock, several mechanisms have been invented and deployed in the construction of an actual clock, which has often been used in cities and within people’s dwellings since the middle ages. Since time immemorial of the evolution of clock, the main purpose, irrespective of accuracy and preciseness of a clock version, is to determine time in lesser units relative to the accepted units of time such as a “calendar day, a lunar month, and or a year” (Itano & Norman, 1999, p.56). Watches are version of clocks, which can be carried by an individual.
