Huygens contracted the construction of his clock designs to clockmaker Salomon Coster, who actually built the clock. He described it in his manuscript Horologium published in 1658. The pendulum clock was invented on 25 December 1656 by Dutch scientist and inventor Christiaan Huygens, and patented the following year. The first pendulum clock, invented by Christiaan Huygens in 1656 Any motion or accelerations will affect the motion of the pendulum, causing inaccuracies, so other mechanisms must be used in portable timepieces. Pendulum clocks must be stationary to operate. Pendulum clocks are now kept mostly for their decorative and antique value. : p.623 The home pendulum clock was replaced by less-expensive synchronous electric clocks in the 1930s and '40s. Their greater accuracy allowed for the faster pace of life which was necessary for the Industrial Revolution. Throughout the 18th and 19th centuries, pendulum clocks in homes, factories, offices, and railroad stations served as primary time standards for scheduling daily life, work shifts, and public transportation. From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. The advantage of a pendulum for timekeeping is that it is an approximate harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. That way is it complete and done the best and quickest way.Vienna regulator style pendulum wall clockĪ pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. In both situations it is best to replace the entire component with the click and spring together. This maybe the ratchet wheel on a chain driven clock or a cable drum for a cable driven clock. It will have the click and spring on it all as one unit. Replacing the entire wheel will include the ratchet wheel, the arbor it is on and also the gear. If you need these for a weight driven ratchet wheel it is best to replace the entire wheel. In general, this is a harder style to replace and not really available on the market. Once the click on the ratchet slips the mainspring lets loose and momentum of it unwinding is unstoppable. It is not uncommon to think the mainspring broke when really the click eventually came loose and let the mainspring slip. Replace or tighten the loose click to ensure it will not let go when winding the clock with the key. Often when a mainspring breaks the click will loosen considerably from the shock. The click is held in the down position with some pressure from what is known as a click spring. This is the small part that makes the wheel turn in only one direction. It spins one way and makes a clicking sound when this is done. Both have a ratcheting function as in a wheel being able to turn one way only. This can mean a spring driven clock or a weight driven clock.Ĭlicks keep it wound in only one direction. Mechanical clocks with a ratchet wheel use clicks. Clockworks offers them in an assortment of 100 to ensure the right one is there. A taper pin is a small brass or steel rod that is wide on one end and skinny on the other. Insert the taper pin into the hole in the end of the minute hand arbor to secure the washer and minute hand to the clock. Use a taper pin to secure the hand with the washer on top of it. Clockworks offers an assortment of 100 clock hand washers that includes all the styles above. The washer may have a small square hole, or large, oblong or round hole. These secure the minute hand as an alternative to the hand nut. Some antique mechanical clocks require a clock hand washer and a tapered pin instead. However, not all clocks require a hand nut. German hand nuts fit most post war German made mechanical clocks, with the exception being a few large grandfather clocks. So, the American clock hand nuts fit many of the mechanical time strikes that were so popular. The cuckoo hand nuts fit about 80% of the post war German made cuckoo clocks. Generally speaking, what we have to offer in the three types of clock hand nuts will cover most of the post 1930 Mechanical clocks. However, with even all of these assortments, there is a chance none of them will work on the clock. This includes cuckoo hand nuts, American clock hand nuts, or German hand nuts. Subsequently, any hand nut we offer, may, or may not, work. In other words, it is literally trial and error. However, prior to around 1930 there is no telling what will work. There were not many standards on what the hand nut size should be on the early clocks. So, the hand nuts Clockworks offer are for movements made after the 1930's. As we said before, the older the clock the harder things are to find. One of the most common parts a Mechanical clock needs is the hand nut.
