It is considered one of the earliest modifications to make the principle of resting inhibition (deadbeat) usable for pocket watches. Due to its optical function and regional distribution, it is also known in English as "Chaffcutter" ("Häckselmaschine"), "Ormskirk" or "Club-footed verge". Two identical mirrored gears are seated on the same shaft. The teeth of the two wheels fall alternately on the pallet. While a tooth rests on the flat base (rest phase), the next tooth glides over the slant of the pallet during vibration and gives the balance a drive impulse.
