ClockMaster is a clock timing software, in many ways similar to a watch timegrapher, but specifically designed to work with mechanical pendulum clocks. Many modern clocks use a variation of the recoil escapement, where instead of a solid anchor a bent strip of metal is used. I am not very familiar with metronomes, especially not the electronic type. If we added another 6:1 wheel/pinion it would yield a 36:1 gear ratio, giving us 180 hours (7.5 days) on a single winding. Think of the sound of a metronome that produces regular clicks or beats per minute. One of John Harrison'ss clocks is declared the most accurate pendulum clock in the world. Heres a detailed explanation of how mechanical pendulum clocks work. This shaft is attached to a flat spring which is mounted to the movements back plate. With your thumb, stop the balance wheel from turning. I looked up the model number on the paperwork on the back of the clock, it is S1624;, therefore; It is an Ingraham. thanks alot i will continue too fine tune. Again remember to grasp the hand close to the bushing when making this adjustment. It involves a beat detecting device that counts out the beats per hour, or the beats per minute. Apparently a second movement was also used with a slightly different beat rate. what to do if the clock runs fast when wind and then slows as it runs throughout the week? These are very visually interesting escapements, and so are most often used in fancy skeleton clocks. Thanks so much for your information regarding clocks running fast or slow. Enjoy reading your comments. This is a more involved way and usually just done by clock makers. I was hopeful it had done the trick, it was a small device for the extention attached to the pendulum at the top end. i HAVE CHECKED THIS CLOCK AT LEAST 20 OR 30 TIMES AND CANNOT FIND ANYTHING WHERE i CAN SET THE sLOW OR FAST THERE IS NO SCREW TO TURN OR ANYTHING AS i CAN SEE. like so many beats to an hour etc.? This combination of wheels and pinions driving each other is called atrain. The anchor wire is typically the pivot for the pendulum, so this is a very mechanically simple escapement. A pendulum clock is a clock that utilizes a pendulum, a swinging weight, as its timekeeping component. It is a Kundo anniversary clock made in the 1950s. The pendulum swings back and forth, and the clock uses the pendulum's swing to keep accurate time. 2.03 hours fast per day. The 2 in the equation comes from the escapement pallets these act as a simple gear with 2 teeth. It all runs nicely after reassembling it but its losing a couple of minutes per day. I have a 38-year old wall clock that I purchased from South Korea and my wife's helper inadvertently dropped the clock, cracking the wood case when it hit the floor. They were commonly used on low-cost clocks, and are popular amongst modern clockmakers. The formula for this is shown below where L = Length in metres, g = acceleration of gravity at the earths surface. It does not strike the hours. I'll share this with him so he can finally adjust it. Required fields are marked *. Calculating seconds per pendulum period The minute hand takes one hour to turn, so the minute wheel takes the same time to make one full turn. I found an old wind up mantel clock in an op shop. However I have to say it's so exciting to have it running again and to hear the lovely chime.. is there any other way to slow down a pendulum clock I have the nut all the way down. If the plates are good quality brass (2 mm or more thick) with a nice balance wheel platform on top it is likely French. It is held in place on the center wheel pivot by a friction spring, which allows the shaft to turn without moving the center wheel (handy for setting the clock). Ideas? I had no idea that there was so much that went into these clocks! Tip: You can get close to 1 minute by positioning the wheel approximately 3 cm (approximately 1.18 in.) Scientific principles govern what affects the swing rate of the pendulum. The cannon pinion is very different than the other pinions. I have been told it can't be repaired due to lack of clock motors . In general, the gear ratio for a train of n gear/pinion pairs can be calculated as: (W1 * W2 * * Wn-1) / (P2 * P3 * * Pn). Scientists develop a clock that will lose one second every 13.8 billion years. A few of the gears inside will move as you turn the hand so that the hour hand will move accordingly. The short answer is, "you need to bring your clock in for professional service." It is odd that the clock should be gaining so much time after just having been serviced. Rhythm does not make parts available to other repair centers. It's interesting that sliding the bob on a cuckoo clock actually speeds up and slows the time. If you didn't know the power had gone out, you wouldn't know that your clock was inaccurate! This is achieved with item 3, Regulation. These wheels are large, but not out of the question. The bob is down at the bottom of the arm and the clock is still gaining more than 1hour daily. . This is far from an exhaustive list as there are a large number of different BPH combinations used over the years. The closer the weights are to the center, the escape wheel, and thus the clock, speeds up. You should call the service center and see what suggestions they make. The main problem with it is that it runs too slow. This ensures the pendulum doesn't change length with . The rack looks kind of like part of a gear (say a fourth). In the real world, most regulator clocks use a pendulum significantly shorter than the theoretical length and still beat perfect seconds, while smaller clocks often use pendulums much longer than the theoretical pendulum. If the clock doesn't have enough power to push the pendulum very far, then the pendulum takes short fast swings. The seller claimed the clock chimed perfectly and kept accurate time. Takeaway. tock) the clock is "out of beat" and will run fast. Change the items in the yellow boxes and see the Results below. When I received the clock it will only strike the half hour on its cathedral gong. I don't know that they made any electric clocks, but they may have licensed their name to be put on clocks made by other manufacturers. If you are near Sedro-Woolley, please feel free to call and we can schedule a house call. As a rule of thumb, you can assume a fully wound spring will be able to rotate the barrel around 5 times. My dad has been trying to figure out how to fix the time on our Grandfather Clock that has been with our family for generations. Energy Sources: Weight-Driven and Wind-Up Clocks. A pendulum or a bob attached to a rod. . The length of the pendulum determines its natural oscillation rate, and it requires a fairly significant force to overcome its natural rate, which makes them ideal for regulating clocks. . How it Works If it doesn't work, I guess we'll just have to call a clock repair service. I have worked in the electronics field for over 40 years. If we consider a typical 6:1 gear ratio for the single gear and pinion in a power train (lets say a 48 tooth barrel and 8 tooth pinion on the center wheel), then we would get 30 turns of the center wheel on a single winding of the mainspring. ** Recommend to plug a microphone. i'VE BEEN LOOKING SIDE OF THE BALANCE WHEEL AND ALL AROUND THE WHEEL AND i SEE NOTHING WHERE i CAN ADJUST THE MOVEMENT tHANKS FOR ANY HELP. I have two questions. can a metronome be used to calibrate a pendulum clock. There is another way, its called setting the beat rate. I have a nutcracker German Clock; I can turn with key clockwise, but does not seem to turn counter clockwise; how do I slow the pendulum down and how do I keep it going; and how do I move the hands to set initially? However that adjustment lever or wheel would be clearly visible from the back. Clock makers method for Mechanical Clock Pendulum Lengths There is another way, its called setting the beat rate. Thanks for your page, I have learned a lot! Answer (1 of 6): The to and fro movement seen in simple pendulum while one sways it is explained under simple harmonic motion or simply SHM. . TheEscapementis the end of the clocks gear train, and perhaps most important component of the train. You also may remove the pendulum and move the crutch with your finger to the left or right until the proper tick tock is reached. . I just had it serviced, but I had to go all the way to El Paso Texas to do the service because there are no clock repair shops in Las Cruces NM and I'm about 40 miles West of Las Cruses. Re your paragraph on clocks with balance wheels - do you move the lever towards plus if the clock is running slow or vice-versa? It involves a beat detecting device that counts out the beats per hour, or the beats per minute. Most pivots will also have apinionmounted on them as well. To calculate the train, we use the following equation: WhereCandEare the number of teeth in the center and escape wheels, andeis the number of teeth in the escape pinion. Secure the screw into the wall, angled upward at a 45 degree angle, and hang the clock. Note that the first pinion and last wheel do not show up in the equation they do not have any bearing on the gear ratio, since they do not mesh with another gear. But would moving the fork closer to or farther away from the regulator pivot do more? In the verge and foliot escapement, two pallets are attached to a vertical rod called a verge. This is far from an exhaustive list as there are a large number of different BPH combinations used over the years. Take heart there's nothing wrong. A musician then uses this "ticking" from the metronome to follow the proper rhythm given by the tempo. The Rhythm clocks that I am familiar with are quartz clocks, but quartz clocks generally weren't affordable in the 1960';s and early 1970's. help? Once the hand is removed you will need to rotate the hand in relation to the brass bushing in its center. The Verge escapement is very unusual in that it uses a horizontally-mounted escape wheel. Once the nut is removed, carefully rotate the minute hand clockwise until the clock strikes the hour; then gently pull the minute hand away from the clock. http://www.toddfun.com/2016/11/02/how-to-setup-a-grandfather-clock-in-beat-and-. If we throw pinions into the mix, things get even more interesting. The most likely problem is that there is dirt and/or wear in the time train. Measuring the center of mass of a pendulum is difficult as it depends on the type and design of the pendulum. Best regards, A pendulum clock is a clock that uses a pendulum, a swinging weight as its timekeeping element. Hello Steve, the R stands for retard and the A stands for Advance (or their French equivalents). Horolovar templates. The NAWCC is dedicated to providing association services, promoting interest in and encouraging the collecting of clocks and watches including disseminating knowledge of the same. This type of escapement was typically used in only the best-quality clocks and chronometers. . The limiting factor in how long the clock will run is how many times the spring can be wound for a spring-driven clock, or how far the weights can fall for a weight-driven clock. Unfortunately, ours is not a perfect world. My guess is that you have this type of striking mechanism and that for some reason, the lever that holds the rack up isnt releasing the rack to fall, and so each time the clock only strikes once. I will move the minute hand to be on time, but it chimes when the minute hand points two minutes before the actual time. The worn pivot holes result in increased friction that reduces the power available to push the pendulum back and forth. The concepts behind gearing is basic physics, so like any good physics example we will start by considering the theoretically perfect gears two toothless disks like these. Why does a clock run fast when it isn't getting enough power? Moreover, the arbor carrying the minute hand comes with a slipping clutch that allows the hands to identify the accurate time. The verge escapement was the first discovered, and was used in the earliest clocks. Pinions ride on the same pivot as the wheel, so therefore they turn at the same speed as the wheel. Enjoy the Fourth of July. I have been having trouble with my anniversary clock and I think it might be smart to take it in to get it repaired professionally to make sure I don't accidentally make it worse. While it is technically a pinion, it looks very different from the other pinions in the clock. Wind-up clocks utilize a spring for power. Like now it is about 10 min on the hour off. I have a couple that I think you should check out: 1) Check that the clock is "in beat." The bob will settle lower, making the effective length of the pendulum longer. To put the clock in beat, ensure that the pendulum overswing in both directions is equal. Many grandfather clocks have 60 beats per minute. I removed the Second Hand and tried again. A ubiquitous "kitchen clock" has a beat rate around 9300 beats per hour, which multiplied by 168 hours in a week, means the clock ticks 1,562,400 times per week. If we were to use a 2:1 ratio, the results are even better: c = M/2(c+M) = (m+H) => H = (3M/2)-m(M*H)/(c*m) = 12 => H = 6mWhich leaves us with:M = 14m/3. For lyre pendulums, the center of mass is above the center of the bob. Best regards, The clock is very precious to me and I don't want to damage it. The pendulum needs to swing exactly equal distances from dead center to the left, as from dead center to the right. . However, from your discription I am going to guess that your clock was made by Ingraham. It is running about 3 hours slow. There is no lever as described above but I do have two nuts labelled s and f either side of the balance wheel. Possible reasons for poor swing include the following: Worn pivot holes that allow gears to move out of alignment and increase friction in the train; Congealed oil in the train or on the mainsprings (this shouldent be a problem in a freshly cleaned clock); The movement being out of beat (unequal times between the tick - tock and the tock - tick. I cannot make it chime, Its been wound up Our 2-second pendulum then makes 60 beats per minute, for example. Ronell Clocks, Timesavers, and Merritts Antiques all carry double ended clock keys. So the question now becomes: What good is this theoretical length? If it really is that old and has a battery, it probably has a balance wheel like a wind up watch. In a pinch, a coffee mug or a book will do -- it doesn't really matter. Now you can hang the weight on the pulley and wind the clock by rotating the handle clockwise. Clock makers method for Mechanical Clock Pendulum Lengths. Once you have established the approximate position of the bob, you can cut the shaft and thread it for arating nutto allow fine adjustment. If you have any problems, it might be a good idea to find a clock repair services that have experience with the kind you have, such as the pendulum or balance wheel ones. Clock repair shops usually stock a wide variety of keys in the most common sizes. My wife loves old wall clocks, and has a few that need to be repaired. There are people who rebuild rotors. When the pendulum swings to the other side, the process is reversed. Ive stripped down and cleaned the movement and re-oiled all the pivot holes. (Daisy bell song) I then removed the Hour Hand and replaced the Minute Hand and, still nothing. The long answer explains why. A mantel clock with a Westminster chime I was told' the sound of which I hadn't heard since my pre-teen years! Hamilton was a major American producer of high end watches. The gear ratio calculation for this gear sequence will give us the number of swings of the pendulum that will result in the center wheel making one rotation. The PCD is the point at which the meshing gears actually touch, and is the same as the diameter of the theoretically perfect gear. Then the gravitation pull on the primary weight powers the gears in the clock. More specifically, its ticks at about 105 instead of 120. Hamilton West Mister Chime 8 day Wall Clock and its running to slow. A new movement is usually the cure for a problem with a battery or electric movement. ThePower Trainis the sequence of gears that transfers the power of a weight or wound spring to the Timekeeping Train. So how do we prevent the disks from slipping, without unduly increasing the friction? The foliot is a cross-bar attached to the top of the verge. With careful selection of gears and pendulum length, we can precisely control the rate of rotation of the center wheel. Instead, once an hour a pin on one of the wheels catches the tail of the hammer and strikes a bell or gong. If you have access to the movement and a careful eye, you can count the teeth in the time train and calculate the correct beat rate for your clock. If it is battery powered or electric, the pendulum is probably decorative and does not need to be adjusted. Note further that since thecircumferencesof the circle are in contact, if a point on the circumference of disk A moves a certain distance, a point on the circumference of disk B will move thesamedistance. Henry J. The pinion will engage a wheel on a different pivot, thus transferring the power to the next wheel. Clock Time Regulation for iPhone. Some people do not have a repair shop within a reasonable distance from them. However, with this calculation of determining the needed change in pendulum length it is really only important to measure the estimated center of gravity in exactly the same way each time. English carriage clocks are high quality, but very big. Columbia, PA 17512 In fact there is no name brand either. Some very fancy clocks will use even higher gear ratios to run longer on a single winding, but these clocks must make some accommodations for the loss of power due to the high gear ratio. Your movement was probably made by Hermle. This app is to measure the BPH (Beats per hour) of mechanical watches. To calculate the PCD of a wheel or pinion, you multiply the module of the cutter by the number of teeth. The clock has a weight that falls down slowly, and the pendulum's swing controls the speed of the weight's fall. Torsion clocks operate at a very low beat rate. The unwinding of the spring is what powers the clockworks.https://www.youtube.com/watch?v=WE8pO3Zq-z8Video cant be loaded because JavaScript is disabled: How A Mechanical Clock Works (https://www.youtube.com/watch?v=WE8pO3Zq-z8). It's ticking sound, similar to. I completely repaired the clock case and purchased a new clock movement with chime box, assembling everything together. Where do you measure the length from and to what point? The pendulum needs to be lengthened to 22.35 cm. If you cannot adjust the timekeeping of the clock slow enough, that likely means that the clock needs some TLC. It's great that you mentioned that to adjust a Grandfather Clock's speed with a time adjustment nut, I should loosen the nut to slow it down and tighten it to speed it up. Back to menu View Manual. Tie the string to the weight. I had it oiled a while back, and It runs fine, but the problem is that even with the F-S adjustment at full F it still loses about a minute or two a day. Last night, my best friend told me that he and his friend were planning to buy a JB Stamp Barrel Head Clock that he could install in his art studio for better appearance, and he asked if I had any thoughts on what would be the best option to consider. 7-8 minutes a week loss seems like a lot. This is the beat rate of my Office No 2. Do you possibly have an idea as to why the clock is not working as it should, as I know this is a long shot asking you a question when you can't see physically what is occurring at my end. Shorter pendulums swing faster than longer ones do. The app analyzes the ticking sound of the escapement to determine the clock's running rate measured in Beats Per Hour (B/H). If not, there are many great clock repair technicians out there. The adjustment nut is a large nut at the bottom of the pendulum just below the large disk or weight called the bob. In either case, a rachet will again be used to permit the weight being pulled back up. This value is called thetrainof the clock. To be of any use for the purposes of timing, such BPM value has to be specified with at least 3 decimal places. Tap for a few seconds to quickly calculate BPM without waiting the whole minute. If you are in or near the Skagit Valley, I would be happy to look at it. 2) The clock adjusts timekeeping by shortening or lengthening the acting length of the suspension spring which passes through two chops that pinch the spring and that move up and down when you turn the thumb wheel. Not enough power is getting to the pendulum to make it swing as far as it should. The pallets are normally arranged such that each back and forth beat of the pendulum moves the escape wheel forward one tooth. SHM is defined as the motion of the particle where the acceleration and the force is always directed towards the centre or equilibrium position. This is a nice simple train, and one commonly encountered in commercial clocks. Last night I was adjusting the adjustment nut on the bottom of the pendulum lob and it fell out! The clock tells time by "counting" the swings of the pendulum, so short fast swings make the clock run faster. Thank you. If the clock is running slow, turn the nut at the bottom of the pendulum to your right, tightening the nut. Even greater control is possible by moving the foliot weights. Can you help? Shows pendulum motion fully wound up. 514 Poplar Street It's picking up about 45 minutes over the course of 7 days. Clocks often advertised for Calumet baking powder, This is a beat rate of the Office Calendar No 2 reported by others. Thank you. How do I adjust the time keeping? Try moving only forward, because moving hands backwards might stop the clock. On the rim of the wheel you will see a bunch of circles. Many thanks Fortunately, most of this theoretical gobbledygook is not necessary for understanding how clocks work. The F or S is too small for me to see. Volumes of scholarly research have been devoted to horological gear theory, much of it quite mathematically complex. I've tried setting it to the extreme + and - and it still runs fast. The pinion is another gear, much smaller in diameter than the wheel, and with far fewer teeth. Thank you. Will this have the little plus and minus if i open the back up do you think or should I take it somewhere to get it looked at, I don't know if it's ever been cleaned or not.
