bell, LL. clocca, cloca (whence F. cloche); al perh. of
Celtic origin; cf. Ir. & Gael. clog bell, clock, W. cloch
bell. Cf. Cloak.]
1. A machine for measuring time, indicating the hour and
other divisions; in ordinary mechanical clocks for
domestic or office use the time is indicated on a
typically circular face or dial plate containing two
hands, pointing to numbers engraved on the periphery of
the face, thus showing the hours and minutes. The works of
a mechanical clock are moved by a weight or a spring, and
it is often so constructed as to tell the hour by the
stroke of a hammer on a bell. In electrical or electronic
clocks, the time may be indicated, as on a mechanical
clock, by hands, but may also be indicated by direct
digital readout, with the hours and minutes in normal
Arabic numerals. The readout using hands is often called
analog to distinguish it from the digital readout. Some
clocks also indicate the seconds. Clocks are not adapted,
like the watch, to be carried on the person. Specialized
clocks, such as atomic clocks, may be constructed on
different principles, and may have a very high precision
for use in scientific observations.
