Clock Parts And Tools Basics

clockpartsandtoolsA clockmaker is an artisan who makes and repairs a clock. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks. Modern clockmakers may be employed by jewellers, antique shops, and places devoted strictly to repairing clocks and watches. Clockmakers must be able to read blueprints and instructions for numerous types of clocks and time pieces that vary from antique clocks to modern time pieces in order to fix and make clocks or watches. The trade requires fine motor coordination as clockmakers must frequently work on devices with small gears and fine machinery.

Originally, clockmakers were master craftsmen who designed and built clocks by hand. Since modern clockmakers are required to repair antique, handmade or one-of-a-kind clocks for which parts are not available, they must have some of the design and fabrication abilities of the original craftsmen. A qualified clockmaker can typically design and make a missing piece for a clock without access to the original component.

Clockmakers generally do not work on watches; the skills and tools required are different enough that watchmaking is a separate field, handled by another specialist, the watchmaker.

 Clock Tools

Balance Truing Caliper: This device was used in fashioning the wheels and gearwork of the clock, to make sure the wheel, particularly the balance wheel was balanced and circular. The pivots of the wheel were mounted in the caliper. An index arm was moved next to the edge and the wheel was spun to see if the edge was true.
Die/Screw Plate: The die plate was used to cut threads on small screws. It had a number threaded of die holes of different sizes for making different threads. A piece of wire was inserted in a hole and turned to cut a thread on the end. Then a head would be formed on the other end of the wire to make a screw.
File: Hardened steel files was used to shape the metal before it was used to make and fit wheels or plates. There were many variations of files.
Rivet Extracting Pliers: Made of brass or steel, rivet extracting pliers were used to remove rivets from assorted clock parts.
Jeweler’s Piercing Saw: The blade of the saw was released by undoing the thumbscrew adjacent to the handle. To start an interior cut, a hole was drilled and the blade was inserted and reattached to the saw. This device was popular among clock makers to repair the ends of clock hands.
Staking tool: An iron vertical plunger was used with an array of stakes for placing rollers and balanced wheels on staffs.
Turns: The "turns" was a small bow-operated lathe used for furbishing parts and for working gear blanks to size. During use, the device was clamped in a vise and the worker held a cutting or polishing tool on a tee-shaped tool rest with one hand, and shifted the bow back and forth to spin the part.
Cross Peen Riveting Hammer: The flat end of the tool was for general use, whereas the carved peen end was used for flattening rivet heads. This tool was used for forging, riveting, striking steel, etc.

What is a clock

clockpartsandtoolsA clock is an instrument used to indicate, keep, and co-ordinate time. The word clock is derived ultimately (via Dutch, Northern French, and Medieval Latin) from the Celtic words clagan and clocca meaning "bell". A silent instrument missing such a mechanism has traditionally been known as a timepiece. In general usage today a "clock" refers to any device for measuring and displaying the time. Watches and other timepieces that can be carried on one's person are often distinguished from clocks

The invention of the mechanical clock in the 13th century initiated a change in timekeeping methods from continuous processes, such as the motion of the gnomon's shadow on a sundial or the flow of liquid in a water clock, to repetitive oscillatory processes, like the swing of a pendulum or the vibration of a quartz crystal, which were more accurate. All modern clocks use oscillation.

Although the methods they use vary, all oscillating clocks, mechanical and digital and atomic, work similarly and can be divided into analogous parts. They consist of an object that repeats the same motion over and over again, an oscillator, with a precisely constant time interval between each repetition, or 'beat'. Attached to the oscillator is a controller device, which sustains the oscillator's motion by replacing the energy it loses to friction, and converts its oscillations into a series of pulses. The pulses are then added up in a chain of some type of counters to express the time in convenient units, usually seconds, minutes, hours, etc. Then finally some kind of indicator displays the clock result in a human-readable form.
