Its invention is important in the history of technology, because it made possible the development of all-mechanical clocks. In the absence of an adjustment on the pendulum, there is a regulator on the clock face. In pocketwatches, besides its inaccuracy, the vertical orientation of the crown wheel and the need for a bulky fusee made the verge movement unfashionably thick. [23][24] It consisted of a pair of escape wheels on the same axle, with alternating radial teeth. The torque or power that is developed within the clock gear train via springs or weights, is released to the pendulum through the escapement, and it is the equal distribution of power that keeps the pendulum swinging. Columbia, PA 17512 As the clock's gears turn the crown wheel (see animation), one of its teeth catches on a pallet, pushing on it. Universal Verge Kit comes in a set of 3 pieces.

A power source; either a weight on a cord or chain that turns a pulley or sprocket, or a mainspring. They tell you exactly what to do for what effect. To achieve this in a verge watch requires the crown wheel to be made very small, magnifying the effects of wear. The time keeping with this mechanism is not as good as that of a pendulum because of the numerous variables within the mechanism, but adjustment by positioning the two weights on the Foliot arm can bring it within a reasonable accuracy. The verge rod was suspended between them, with a short crosspiece that rotated first in one direction and then the other as the staggered teeth pushed past. [8][9] There has been speculation that Villard de Honnecourt invented the verge escapement in 1237 with an illustration of a strange mechanism to turn an angel statue to follow the sun with its finger,[10][11] but the consensus is that this was not an escapement. When the hands are touching it usually means they are stuck and your clock will not run.
