The general contrivance in a timepiece by which the pre ure of the wheels (which move always in one direction) and the vibratory motion of the pendulum or balance wheel are accommodated the one to the other. By this contrivance the wheelwork is made to communi cate an impulse to the regulating power (which in a clock is the pendulum and in a watch the balance-wheel), so as to restore to it the small portion of force which it loses in every vibration, in consequence of friction and the resistance of the air. The leading requisite of a good escapement is that the impulse communicated to the pendulum be invari Recoiling and Dead-beat Escapements. able, notwithstanding any irregularity or foulne in the train of wheels. Various kinds of escapements have been contrived: such as the crown-or a cliff.
