Like De Vick's clock also Huygens's clock had its escapement wheel acting upon two pallets.
The escapement is in front, so that every tooth is seen as it frees itself.
A number of years ago we constructed the escapement model which we herewith illustrate.
There is an escapement, Fig. 4, which is just the opposite to the English.
We will again proceed with the delineation of the escapement here illustrated.
When the balance-wheel, impelled by the escapement, rotates, it winds up the spring.
The check in the second action, the "paramartello," is next in importance to the escapement.
The shaft is permitted by the escapement to revolve once an hour.
One escapement maker will divide the impulse equally between the tooth and pallet; another will give an excess to the tooth.
Therefore, the fifth wheel and its accompaniments are called the "escapement."
