Each escapement consist of pivoted rocking frame holding wheel, say, "A" and pivoted in such a way that it meshes with the pinion "B" (10eaves) of the fifth train wheel "C" (10 teeth) resembling an escape wheel. The rocking bar by the force of gravity falls down on the side where the wheel "A" is pivoted. The other side of the wheel meshes with 10-tooth escape wheel so, when the escape wheel is locked, the force of mainspring transmitted by the pinion "B" lifts the wheel A and consequently raises the bar, furnishing constant energy to the escapement. The end of the rocking bar is terminated with a detent that locks the wheel "C"ust after the lifting. The pendulum unlocks the escape wheel which is driven by the falling action of the rocking bar and so delivers an impulse to the pendulum with constant momentum. The pendulum is terminated by a platform holding the impulse pallet and unlocking spring, both with regulating screws. Two spring-loaded steel brackets securing pendulums for transport, four leveling knobs at each corner of the base, with a level at the back of the base, two length-adjustment knobs at the top of te frame.Signed on the movement, the dial, and both pendulums, the subsidiary seconds dials signed "A" and "J".Dim.
