scape-wheel

For this period the escape wheel is "locked" and unable to turn.

The escape wheel, except in unusual cases, has 15 teeth and is made of steel.

The rotation of the escape wheel is controlled by the pallets.

At rest one of the escape wheel teeth will be locked against a pallet.

The two three-legged escape wheels are also coloured blue and red.

Another reason the escape wheel teeth are slanted backward is as a safety measure.

In a 30 tooth escape wheel the pallets span about 7 teeth.

It can also cause the points of the escape wheel teeth to dig into the pallet surface.

Alternatively a 19 jewel watch will have additional cap jewels on the escape wheel.

In this watch the driving escape wheel had 5 impulse teeth and the driven had 4.

When the pendulum lifted one arm far enough its pallet would release the escape wheel.

The drive- and tensioning-weights were made much smaller and drove the escape wheel directly.

The Riefler escape wheel and pallets are of a special design.

As the escape wheel turns, the pallet is in just the right position to receive a push from an impulse tooth.

Each time the pendulum swings through its centre position, it releases one tooth of the escape wheel '.

The hinged pallets both pointed the same way, opposing the rotation of the escape wheel.

A solution is to make the escape wheel and other parts out of harder materials than steel, eliminating the need for lubrication.

The escape wheel tooth then imparts its energy on a second roller on the balance staff.

The fourth wheel also turns the escape wheel pinion.

When the pallet is pushing the escape wheel backwards it is also being driven hard against its stop.

It consists of a gear called an escape wheel, which is released one tooth at a time by a lever that rocks back and forth.

The anchors, escape wheels and other watch mechanisms were also made of non-magnetic metals or alloys.

Pallet jewels interact with the escape wheel.

Another later refinement added by Breguet was the reduction in size of the second (driven) escape wheel.

The escape wheel keeps the pendulum or balance swinging by giving it a small push each time it moves forward.
