Century Dictionary and Cyclopedia

1. To cluck, as a hen.
2. To call by clucking.
3. n. A machine designed to measure and indicate time by the motion of its parts. Clock was the generic name for all such machines; but instruments of this kind designed to be carried on the person are now called watches, and those of special accuracy, used at sea, chronometers. A clock usually consists of a frame or case containing a train of wheels moved by weights or springs and regulated by a pendulum or balance-wheel, carrying hands or pointers round the face or dial-plate for marking the hours and minutes. The dial-plate may have minor dials, as for marking seconds, or be divided into several dials, as for showing the time at different places. Clocks are also most commonly made to give notice of the hour, and sometimes of lesser divisions of time, by the stroke of a hammer on a bell or other sonorous object. See horology.
4. n. A stroke of the clock; the sounding of the hour by a clock.
5. n. A watch; specifically, a watch that strikes the hour.
6. n. A clock operated by a weight in the usual way, and regulated and controlled by an electric current from another clock, an electric escapement being employed in some cases as the direct means of controlling its motion.
7. In bell-ringing, to sound (a bell) by pulling the clapper without moving the bell itself. See clappering.
8. n. In the sixteenth century, a decoration applied to hoods.
9. n. In the reign of Charles II. of England, a gore, plait, or piece inserted to produce the required shape of a garment.

GNU Webster's 1913

1. n. 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.
2. n. obsolete A watch, esp. one that strikes.
3. n. obsolete The striking of a clock.

5. v. To ornament with figured work, as the side of a stocking.
