Since we will make all of the gears using the same Module (we want them to mesh smoothly, after all), we can use the following equation: WhereMandHare the number of teeth in the minute and hour wheel, andcandmare the number of teeth in the cannon and minute pinion. Hi, For instance, assuming the same 1-second pendulum we can use the following gears: Center Wheel: 64Third Wheel/Pinion: 60 / 8Escape Wheel/Pinion: 30 / 8. It's picking up about 45 minutes over the course of 7 days. 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. Thank you. Unfortunately there is not an easy fix. Mike. I found an old wind up mantel clock in an op shop. Strike - Ice Beech 70989T30141. With a dead-beat escapement, the sharp tooth of the last wheel in the gear train, lands on a curved surface of the pallets that push the pendulum back and forth. Can a Metal Roof be Installed Over Shingles? would towards the A, in my case to slow the clock mean, turning Clockwise or Anti Clockwise? Clock Time Regulation for iPhone. Once back together, I checked the hands, the bob, the rod, the verge, everything there is straight and not rubbing. TimeSavers offers several books on clock repair that can help. Re your paragraph on clocks with balance wheels - do you move the lever towards plus if the clock is running slow or vice-versa? I am sure it can. The Module of a cutter determines thepitch circle diameter(PCD) needed for a wheel with a specific number of teeth. I'm hopeful that I will be able to get the right balance now! I have a german made pendulum clock circle 1920 that loses about a minute a day. In this episode of metronome sounds, the metronome is set to 60 beats per minute. The pendulum needs to swing exactly equal distances from dead center to the left, as from dead center to the right. It is theoretically possible to work the other direction to start with the length of the pendulum and calculate the BPH rate it would need to swing at to keep time, however in practice this is difficult, as the critical dimension is from the top of the suspension spring to the center of mass of the pendulum. The pendulum swings back and forth, and the clock uses the pendulum's swing to keep accurate time. If not real time then just beats in a variable time period, ie 1 min or 2 or 5 or 10 min. Yet, when I turn the nob on the backside to turn the minute hand forward, the chimes ring out but the clock refuses to work. But it runs slow. Hamilton West Mister Chime 8 day Wall Clock and its running to slow. I have a ship's clock (chronometer) by Wempe. Put FC = h , and MC = x, and OB = l. This is the same thing a pendulum must do for the clock to run properly. 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. As soon as we got our first TV my dad didn't like the chime interrupting TV programs so the chime was turned off! Columbia, PA 17512 The closer the weights are to the center, the escape wheel, and thus the clock, speeds up. Any advise on how to fix it? So the question now becomes: What good is this theoretical length? Before we get to the detailed explanation of the gear workings of mechanical clocks, lets briefly look at common power sources. These are the components of a mechanical pendulum: 1. can a metronome be used to calibrate a pendulum clock. Thats why you stopped the clock. The friction is the bend in the spring at the top of the pendulum, the light touch on the crutch fork on each swing and air resistance. If we were using a 6-tooth pinion, then, our numbers would be: Cannon Pinion: 39Minute Wheel 39Minute Pinion: 6Hour Wheel: 72. A standard watch crystal of 32.768 KHz is probably the best In general, it is a good starting point for pendulum length, and not much else. I have tried removing the pendulum and rotating the little flywheel to the top and to the bottom as far as the thread will allow but neither extreme seems to make much difference. pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. These clocks keep time by counting the number of swings of the pendulum. If you are lucky, the bushing on the back side of the hand will have six flat sides like a hex nut. This means there are 9600 beats per hour. Danette, This depends on the clock and the type of hands that it has. Metronome is handy for many musicians because it helps them improve their timing skills and play faster songs. So how do we prevent the disks from slipping, without unduly increasing the friction? However, from your discription I am going to guess that your clock was made by Ingraham. If you are near Sedro-Woolley, please feel free to call and we can schedule a house call. Most modern clock hands are mounted on a brass bushing. Good luck. Thank you very much for the reply. These wheels are large, but not out of the question. The vast majority of long case, tall case, grandfather clocks have a seconds pendulum that ideally runs at 3600 Beats Per Hour. Some people do not have a repair shop within a reasonable distance from them. Best regards, 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. It all runs nicely after reassembling it but its losing a couple of minutes per day. Volumes of scholarly research have been devoted to horological gear theory, much of it quite mathematically complex. The cannon pinion drives the minute wheel and pinion, which in turn drive the hour wheel. Required fields are marked *. The actual outside diameter (OD) of the gear is larger than the PCD by a small amount. The Escapement also plays one more very important role it provides a small impulse to the pendulum, which allows the pendulum to overcome friction and keep moving. I have a nice grandmother clock & the time runs fast. 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. document.write(year) Sorry for the late reply. var today = new Date() Worked ok prior but not it won't work. I suggest you contact the Rhythm Clock repair line at 770-640-6311. Ronell Clocks, Timesavers, and Merritts Antiques all carry double ended clock keys. If you cannot adjust the timekeeping of the clock slow enough, that likely means that the clock needs some TLC. 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. Your email address will not be published. Shows pendulum motion fully wound up. When I received the clock it will only strike the half hour on its cathedral gong. I have a couple Timex watches that have a variable capacitor across the crystal to trim the crystal frequency. If it is more uneven, push the leader in the opposite direction and listen to the tic tock again. I recomend the book "The 400-Day Repair Guide" by Charles Terwilliger. These wheels are attached to slender rods calledpivots, which ride in holes drilled in the clock plates. In order to get our cannon pinion and hour wheel to rotate about the same point, we need to make sure that the radius of the cannon pinion plus the minute wheel is the same as the radius of the minute pinion plus the hour wheel. Remember to grasp the hand as close to the minute arbor as possible. var year = today.getFullYear() http://www.toddfun.com/2016/11/02/how-to-setup-a-grandfather-clock-in-beat-and-. Thanks. You will probably have to make several trys before you get it right. This clock makes 10 beats per minute. Using a module .8 cutter, the same wheel would have a PCD of 38.4 mm. These clocks do not have a strike train. I've tried setting it to the extreme + and - and it still runs fast. If they are held together tight enough so they will not slip there will be a lot of friction, which means more power will be required to drive the gears. This ensures the pendulum doesn't change length with . Gregory, These clocks are fun and there is always a lot more to learn! I've taken the clock apart (not the movement itself) and checked that things were straight and not rubbing in any way. Clocks that are dirty or worn rob power from the balance wheel. 7-8 minutes a week loss seems like a lot. Some metronomes give you a steady 4/4 time signature or common time as we also call it. Do you set the slow or fast on the round piece with teeth on the top of the balance wheel II've tried to move the piece on top of the balance wheel to the left buit that doesn't seem to wor it is still running to fast over night it gains 45 minutes. Well a seller can say anything they want to, eh? Clocks which use this type of train are called 8-day clocks, and the extra wheel is typically called the8-day wheel. I have a couple that I think you should check out: 1) Check that the clock is "in beat." Every time the minute hand goes around, MicroSet divides the total number of pendulum swings by the number of minute hand rotations and derives the average Beats Per Hour to two decimal places for that movement. Your key should slide easily onto the arbor, but not so loose that either the key or the corners of the winding arbor can be damaged when you turn the key. My clock is running fast/slow. Scientists develop a clock that will lose one second every 13.8 billion years. For wheels the proportion is 1.38M, while for pinions it is .855M. My clock has two issues: It runs slow and it displays improperly. 13 mins. The clock is very precious to me and I don't want to damage it. Thanks so much for your information regarding clocks running fast or slow. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant. This alternating action thrusts the pallets first one way then the other, causing the verge to swing back and forth. The spring is wound-up as a store of energy. When the pendulum swings all the way to one side, the pallet on one side releases a tooth, and the other pallet catches the next tooth in line. 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. Not 5 mins slow or fast but 10 to 15 either way. Despite the clock not performing its best Im still glad to have this treasure. 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. To make the wheel sizes more reasonable, another wheel and pinion is added to the train. It involves a beat detecting device that counts out the beats per hour, or the beats per minute. With French clocks, the unit of measurement is Pouces with the whole number being to the . to 53.5 cycles per minute by just adjusting the pendulum length and monitoring the error over a several hour period. There is another way, its called setting the beat rate. Fortunately, most of this theoretical gobbledygook is not necessary for understanding how clocks work. The time spent pushing against the locking face acts as a drag on the pendulum which decreases its swing. A musician then uses this "ticking" from the metronome to follow the proper rhythm given by the tempo. Turn your iPhone into a precise train count sensor with an unbelievable 0.001 milliseconds (1s) accuracy!! Siliconized Grout for Tile. English carriage clocks are high quality, but very big. Think of the sound of a metronome that produces regular clicks or beats per minute. I have recently stripped, cleaned and lightly oiled a 1940/50s Smiths mantle clock. If it doesn't work, I guess we'll just have to call a clock repair service. In order to find one, you'd probably want to look online at different professionals to learn about their services and experience so you can find one that is able to fix your clock. I don't know of any new rotors being produced. Bring your mantel clock into your local clock repair shop and they should be able to help you. However, if its is losing 30 minutes a day, you might be out of the range of adjustment. Listen to the tic toc again. Look again 24 hours later and determine how much time has been lost or gained and move the pendulum clock nut accordingly. tock . If you can set the number of beats per minute, and if you know how many beats per minute your clock does, you are set. If it is uneven (tock . tick . 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. Two small, adjustable weights hang from each end. Greetings, I acquired a beautiful 1887 Seth Thomas mantle clock a year ago on eBay. Once again, however, the real world does not fit our perfect world. With a tweezers, move the pointer towards the "-" to slow it down. Can i add some type of weight to the bottom of the nut to correct this? The center wheel pivot extends through the clock plate slightly, and the cannon shaft and pinion is attached to this. Our perfect gears touch at a single point, and never slip. Any thoughts or suggestions would be gratefully received. Setting The Beat of the Pendulum Clock It is odd that the clock should be gaining so much time after just having been serviced. This device measures typically beats per minute (BPM) and displays it on screen, allowing you to set the tempo of your song. 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. The seller claimed the clock chimed perfectly and kept accurate time. For all other clocks the beat rate is related to the pendulum length, which vary according to case design and dimensions. In other words, it is nothing like arealpendulum . The far end of the cannon shaft is filed square to fit the minute hand bushing. The escapement controls the speed of the train by counting beats of the pendulum. I've adjusted the pendulum bob down to its lowest setting which has helped but not cured the problem entirely. The rack has at least 12 teeth and usually a few more. Pendulum doesn't have enough swing: Most mantel clock pendulums need to have at least 2 degrees of swing on each side of the at rest position. I have the nut adjusted to the very lowest position w/o falling off & it still gains about 30 minutes per 24 hours. If you feel it move a little bit, that may correct the problem. I then removed the Hour Hand and replaced the Minute Hand and, still nothing. If a clock is out of beat, the pendulum will swing for a few minutes, then stop even if the clock case is level. TimeSavers (timesavers.com) has a variety of adjustable pendulums for sale. My favorite part of this article is that balance wheels could be an alternative to pendulums, they handle the time of clock. This value is called thetrainof the clock. 2.03 hours fast per day. The movement of the pendulum is transferred to the escapement anchor by means of an arm that straddles the pendulum rod, called thecrutch. If the first explanation is true, then your clock is running properly; if the second explanation is true, you probably need to take you clock in to be serviced. I have removed the hands multiple times and still no success. Enjoy reading your comments. (You can reply by e-mail if that's better.). The PCD is the point at which the meshing gears actually touch, and is the same as the diameter of the theoretically perfect gear. I just got a 31 day korean movement pendulum clock. You may optionally configure it for Beats Per Second (BPS) or Beats Per Hour (BPH). Time it for 30 or 60 seconds and count how many times it . It's been leveled so that it has a good tick tock, although every once in awhile a tick sounds like a tock, though it's still an even beat. The timekeeping is much better now, within about a minute per week. On some clocks there is a theoretical pendulum length stamped on the back plate. and only after twoo days of monitoring, its only losing 1 min. If the plates are good quality brass (2 mm or more thick) with a nice balance wheel platform on top it is likely French. Both of these issues are best adressed by a competent repair person. How it Works per 24 hrs. It does not strike the hours. One interesting variant of the verge that turns up occasionally is the recoil verge. This is far from an exhaustive list as there are a large number of different BPH combinations used over the years. Thanks in advance for any help given! Change the items in the yellow boxes and see the Results below. Pendulums have been used in grandfather clocks and the like to keep time. Best regards, tock) the clock is "out of beat" and will run fast. ClockMaster is a clock timing software, in many ways similar to watch timegraphers, but specifically designed to work with mechanical pendulum clocks. 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. Wheel 2 drives pinion 3 at a 6:1 ratio, we end up with a 48:1 gear ratio for the train! It is beautiful and means a lot to me but was running fast, I found your advice to adjust the pendulum and hope that I can adjust the speed Thank You. To speed up a clock you must make the effective length of the pendulum shorter; to slow down the clock, the pendulum length must be longer. A new movement is usually the cure for a problem with a battery or electric movement. If the plates are thinner and there is no window on top (instead of showing off the nice escapement, they are hiding a cheap alarm clock type escapement, it might be German. Hi Mike, 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. A clock comes in for repair with a replacement pendulum. Hi! . Also we armature radio operators do the same thing to twitch the freq on our crystal transmitters. If you are near Sedro-Woolley feel free to bring it by during regular business hours. You can try www.KensClockClinic.com. I use an Atomic Clock to check all my clocks time keeping. tock). Please see the FAQ for putting a clock in beat. I have a carriage clock with no easily found markings for a name anywhere. Thanks! When the pendulum swings to the other side, the process is reversed. Another possibility is that the clock was made by Hammond. Energy Sources: Weight-Driven and Wind-Up Clocks. Move the small wheel up and down the pendulum until you find a position where the pointer goes around the dial in approximately 60 seconds. The oscillator circuit uses an old 20KHz quartz crystal, but other low frequency crystals can be used. I have got it running and fixed the striker but it only strikes once on each hour. A primary weight is lifted with a counter-weight as a store of energy. Sorry, I think I mise this. Now you can hang the weight on the pulley and wind the clock by rotating the handle clockwise. For example, if disk A is 100mm in diameter and disk B is 50mm, the gear ratio will be 2:1 B will rotate twice for every rotation of A. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); In a weight-driven clock we have considerably more leeway. These anchors are slightly less accurate than the solid, but much easier to adjust. Thus, I haven't the slightest idea as to why it won't work. A pendulum is a weight suspended from a pivot so that it can swing freely. 13 mins. Weight-driven clocks use the gravitational pull of a weight for power. . About the sick rooster noiseif the cuckoo sounds loud and obnoxious it is probably working fine. The snail cam rotates once every twelve hours. The barrel is attached to the gear with a ratchet, allowing it to be turned backwards for rewinding. This app is to measure the BPH (Beats per hour) of mechanical watches. Others have published much longer lists of clock BPH rates. Then the gravitation pull on the primary weight powers the gears in the clock. This single-gear setup was common on smaller clocks and lower-cost clocks in the past, and is still in use for some low-end cuckoo clocks to this day. Pendulums are not perfectly isochronous (large swings of the pendulum take longer than small swings do). Also, it is better to set the time a few days after winding . The worn pivot holes result in increased friction that reduces the power available to push the pendulum back and forth. Be careful however, many do not. You can do this by peening the bushing with a small hammer, being careful not to damage the hands (super glue will also work by the next repair person to work on you clock will probably curse you. A pendulum or a bob attached to a rod. Contact the Webmaster for perceived copyright infringement (DMCA Registration Number 1010287). The Timekeeping train revolves around the center wheel. ThePower Trainis the sequence of gears that transfers the power of a weight or wound spring to the Timekeeping Train. I figured I can try to adjust that again once I get the speed figured out. I replaced the AA Energizer Batteries in the Clock Movement and still the hands haven't moved. Clock makers method for Mechanical Clock Pendulum Lengths. The pinion is another gear, much smaller in diameter than the wheel, and with far fewer teeth. Shorter pendulums swing faster than longer ones do. Hey Mike, I have a father chime clock my wonderful lady got for me. Theres actually a lot of very interesting math behind these shapes, but Ill refer the interested readers to thebibliography below. Will the addition of bushings decrease the value of my clock. Kim. 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. the bird sounds like a rooster with a cold, can this be remedied???? Most have a recoil escapement that turns the gear train backwards just slightly as the pendulum swings past the tick or tock but before it reverses direction. Id also like to mention when I got the clock the seller had placed a lot of packing material (cotton fiber) inside of the clock. Calibrating to 1 Minute It is possible to calibrate to almost 1 minute. In clocks there are almost always exceptions to every rule, so set the time, turn the dial to the right and see if the clock is slowing down. Then, the pallets catch another tooth on the opposite side and let it escape. $ 1,218.00 $ 812.00. There are three particular types of escapements that account for a vast majority of the clocks made: The Recoil escapement is so named because at the very end of the pendulums arc, the escape wheel actually movesbackwardsa tiny amount.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'uwoodcraft_com-square-1','ezslot_32',126,'0','0'])};__ez_fad_position('div-gpt-ad-uwoodcraft_com-square-1-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'uwoodcraft_com-square-1','ezslot_33',126,'0','1'])};__ez_fad_position('div-gpt-ad-uwoodcraft_com-square-1-0_1');.square-1-multi-126{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:15px!important;margin-left:auto!important;margin-right:auto!important;margin-top:15px!important;max-width:100%!important;min-height:250px;min-width:250px;padding:0;text-align:center!important}. Fortunately, they are relatively cheap. . I found an anniversary clock in a thrift store that needed a new suspension spring. This page includes instructions and an online calculator if you wish to try this method. Hamilton was a major American producer of high end watches. Hopefully, modeled keyhole should work just fine as it is common way of hanging stuff on a wall. But if the clock is fast, indicating a time ahead of real time, stop the pendulum until after real. Thus as the movement becomes worn, the push the gear train gives to the pendulum is decreased, but the drag on the pendulum during locking is also decreased, so the arc of the pendulum can actually increase and the clock can slow down. i ALREADY TRIED TO MOVE THAT. There is no way that we could come up with an equation to handle all of the various parameters, so again we turn to the physicists dodge of assuming a perfect abstract pendulum. Look at the American Watchmaker's - Clockmaker's Institute website for their "Find a Professional" page. The biggest problem is timing the clock to the correct beats per min when adjusting pendulum length. Thank you. I assume that the clock has a pendulum. Get a quick and precise drift reading 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.
