VERGE ESCAPEMENT Meaning and
Definition
-
The verge escapement is a type of mechanical escapement mechanism that is commonly used in clocks and early pocket watches. It is responsible for providing accurate timekeeping by controlling the release of energy from the mainspring.
The verge escapement consists of several key components including a crown wheel, a verge, and an escape wheel. The crown wheel is connected to the mainspring and rotates continuously, providing the necessary energy to power the timepiece. The verge is a horizontal bar with pallets that engage with the escape wheel teeth, creating a periodic interruption to allow the clock to tick. The escape wheel rotates back and forth as it engages with the pallets on the verge, transmitting energy to the pendulum or balance wheel, which regulates the motion of the timekeeping element.
When the pendulum or balance wheel swings back and forth, it causes the verge to rock, which in turn releases the escape wheel and enables it to advance by one tooth. This release of energy allows the clock to keep accurate time by converting the rotary motion of the crown wheel into the oscillating motion of the timekeeping element.
The verge escapement is characterized by its simplicity and reliability, making it a popular choice for early clockmakers. However, it is important to note that the verge escapement is not as accurate as more modern escapement systems, and it is prone to issues such as friction and wear, which can affect its performance over time.
Etymology of VERGE ESCAPEMENT
The term "verge escapement" has its roots in the field of horology, which is the study and measurement of time.
The word "verge" comes from the Latin word "virga", meaning "rod" or "stick". In this context, it refers to a vertical swinging arm with pallets attached to the balance wheel in a mechanical clock or watch. The verge escapement was one of the earliest types of escapements used in mechanical timepieces.
The term "escapement" comes from the Latin word "escapare", which means "to escape". In horology, an escapement is a mechanism that controls the rotation of the gear train in a clock or watch, allowing the release of energy from the mainspring or weight, and regulating the movement at a precise rate.
