Whatever may be the system or kind of escapement employed, the
functioning of the mechanism is characterized by the suspension, at
regular intervals, of the rotation of the last wheel of the train and in
transmitting to a regulator, be it a balance or a pendulum, the power
sent into that wheel.
ESCAPEMENT THE MOST ESSENTIAL PART.
Of all the parts of the timepiece the escapement is then the most
essential; it is the part which assures regularity in the running of the
watch or clock, and that part of parts that endows the piece with real
value. The most perfect escapement would be that one which should
perform its duty with the least influence upon the time of oscillation
or vibration of the regulating organ. The stoppage of the train by the
escapement is brought about in different ways, which may be gathered
under three heads or categories. In the two which we shall mention
first, the stop is effected directly upon the axis of the regulator, or
against a piece which forms a part of that axis; the tooth of the escape
wheel at the moment of its disengagement remains supported upon or
against that stop.
