picture description: This is an old fashioned clock. Modern clocks track time usually using a computer chip however this clock uses a mechanical device to count the seconds. The clock has a front plate with numbers written on it as one through twelve. The mechanism moves two indicator bars. The shorter bar moves once every twelve hours thus corresponding to the hours. Tthe longer indicator moves once every hour. This therefore indicates the minutes. On this clock these "hands" indicate ten minutes to four. There are also two smaller hands that show the seconds. The copper bells on top are used as an audible indicator. These are hollow so when they are struck they vibrate and make a sound audible to humans. The mechanism in the clock stores energy in the form or a wound spring that then is released mechanically at a given time set also mechanically. This bell can then alert us that it is a specific time.
