On this Wikipedia the language links are at the top of the page across from the article title. [31] This reduced the pendulum swing to around 50 and reduced recoil (below), but required the verge to be located so near the crown wheel that the teeth fell on the pallets very near the axis, reducing initial leverage and increasing friction, thus requiring lighter pendulums.[31][32]. The result is to change the rotary motion of the wheel to an oscillating motion of the verge and foliot. The name verge comes from the Latin virga, meaning stick or rod.[1].
