The arm L serves todisengage or unlock the wheel by lifting the lever D upon thereturn oscillation of the pendulum. A careful study of Fig. 150 will discover a simple transpositionwhich it became necessary to make in the clocks, for the effectualadaptation of the pendulum to their regulation. The verge V wasset up horizontally and the pendulum B, suspended freely from aflexible cord, received the impulses through the intermediation ofthe forked arm J7, which formed a part of the verge. A
