Verge escapementThe verge (or crown wheel) escapement is the earliest known type of mechanical escapement, the mechanism in a mechanical clock that controls its rate by allowing the gear train to advance at regular intervals, or ticks. Verge escapements were used from the late 13th century until the mid 19th century in clocks and pocketwatches. The name verge comes from the Latin virga, meaning "stick" or "rod".
Pendulum clockA pendulum clock is a clock that uses a swinging weight known as a pendulum as its timekeeping element. The pendulum is an approximate harmonic oscillator that swings in a time interval that depends on its length, and that resists swinging at other rates. From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise type of timekeeper.
Balance wheelA balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or hairspring. It is driven by the escapement, which transforms the rotating motion of the watch gear train into impulses delivered to the balance wheel.
Clock towerClock towers are a specific type of structure that house a turret clock and have one or more clock faces on the upper exterior walls. Many clock towers are freestanding structures but they can also adjoin or be located on top of another building. Some other buildings also have clock faces on their exterior but these structures serve other main functions. Clock towers are a common sight in many parts of the world with some being iconic buildings.
ClockA clock or chronometer is a device that measures and displays time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month, and the year. Devices operating on several physical processes have been used over the millennia.
Water clockA water clock, or clepsydra (from Ancient Greek (klepsúdra)'pipette, water clock'; from (kléptō)'to steal' and (hydor)'water'; lit.' water thief'), is a timepiece by which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel, and where the amount of liquid can then be measured. Water clocks are some of the oldest time-measuring instruments.
Striking clockA striking clock is a clock that sounds the hours on a bell, gong, or other audible device. In 12-hour striking, used most commonly in striking clocks today, the clock strikes once at 1:00 am, twice at 2:00 am, continuing in this way up to twelve times at 12:00 mid-day, then starts again, striking once at 1:00 pm, twice at 2:00 pm, and the pattern continues up to twelve times at 12:00 midnight.
BellA bell () is a directly struck idiophonepercussion instrument. Most bells have the shape of a hollow cup that—when struck—vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell (jingle bell).
Clock faceA clock face is the part of an analog clock (or watch) that displays time through the use of a flat dial with reference marks, and revolving pointers turning on concentric shafts at the center, called hands (or arms). In its most basic, globally recognized form, the periphery of the dial is numbered 1 through 12 indicating the hours in a 12-hour cycle, and a short hour hand makes two revolutions in a day. A long minute hand makes one revolution every hour.
Church (building)Place of worship for Christians Husby Sjuhundra Church (Evangelical-Lutheran) in Norrtälje, Sweden. Its church bells (housed in the belltower) are used to call the faithful to Christian prayer and worship. Trieste Cathedral, a church dedicated to Saint Justus, completed in 1320. It featured iconography of the Virgin and Child.
WatchPersonal timepieceA Rolex Oyster Perpetual with a "Jubilee" dialA 1983 Casio watch with touchscreenA watch is a timepiece carried or worn by a person. It is designed to maintain a consistent movement despite the motions caused by the person's activities. A wristwatch is worn around the wrist, attached by a watch strap or another type of bracelet, including metal bands or leather straps. A pocket watch is carried in a pocket, often attached to a chain.
Town hallIn local government, a city hall,town hall,civic centre (in the UK or Australia), guildhall, or municipal hall (in the Philippines) is the chief administrative building of a city, town, or other municipality. It usually houses the city or town council and at least some other arms of the local government. It also often functions as the office of the mayor (or other executive), if the relevant municipality has such an officer.*As an Amazon Associate I earn from qualifying purchases.
