The radical difference, however, was a newly designed escapement that featured a horizontally placed pivoted detent that allowed the balance to vibrate freely, except when impulsed by the escape wheel.
42.
The necessity for oil on the lever impulse surface resulted in oil being transferred, via the escape wheel teeth, to the direct impulse pin on the balance for the alternative impulse.
43.
Its purpose is to make sure the fork is in the right position to receive the impulse pin if a jar to the watch prematurely'unlocks'the lever from the escape wheel.
44.
As shown in the diagram, the escape wheel rotates clockwise and the entrance tooth is locked in place against the entrance pallet, the lever held in place by the left banking pin.

The shortcomings that caused him to cease development could well include those listed by George Daniels : extra friction caused by the additional escape wheel and instability caused by backlash between the meshing escape wheels.

47.
Unless the ends of one of the pallets is long enough to sit into the gap between the teeth of the escape wheel then the wheel will run free as soon as the clock is wound.
48.
The anchor consists of an escape wheel with pointed, backward slanted teeth, and an " anchor "-shaped piece pivoted above it which rocks from side to side, linked to the pendulum.
49.
Each time one pallet moves away from the escape wheel, releasing a tooth, the wheel turns and a tooth on the other side catches on the other pallet, which is moving toward the wheel.
50.
The Swiss lever, although the mainstay in the industry, has the capability to be strong on energy conservation but needs considerable lubrication between the impulse pallet and the escape wheel teeth due to sliding friction.
