I never thought that with 4 dials you would need a gearbox and 4 driveshafts. And a smaller clock inside mated to the big clocks so you can set the time. May this beauty live forever...love it!
2:503:57 the top one is exactly what I was curious about. I had this unending curiosity about how the motion of the pendulum could be turned into a 2-tick sound a clock is known for. I had recently stumbled upon a rough idea for a 1-way gear that just so happened to contain the input as a back & forth motion, so I’m glad to see a practical example :)
I’m twenty-nine years old now and it’s hard to believe I haven’t thought about this before, but the various pre-clock methods of timekeeping are much more easily described in writing. If it weren’t for the video I’d have been left behind at the graduated oil lamp! Thank you so much.
WOW!! & THANKS!!! I stumbled upon this GREAT video and realized that I had never asked myself this question. Now our entire family is wiser. Thanks for an engaging & easy-to-understand tutorial. The Keenans in Austin, Texas
Sir, with great respect, may I point out a slight misconception. At 3:08 it is said that each axle turns faster than its predecessor with less "power". Well, if one considers the losses as one moves through the gears, that is correct, but neglecting losses the power transmitted at any stage is the same. Power is Force multiplied by velocity. It is the force that changes or shall we say torque. All the "energy" is stored in the lifted weight and the rate at which this is used is "power". Apart from that, this is an excellent video, my congratulations. It is a beautiful elegant machine.
Correction...the axle shafts have about the same amount of power each...except for friction loss. The power goes as Torgue x Angular Speed. Each shaft has differing torques and speeds. In inverse proportions.
A very interesting video. I am fascinated with mechanical clocks of many varieties. It was a treat to see inside a large-scale work of art such as this. Thanks for posting!!
Thank you so much for posting this amazing video of such a wonderful and marvelous machine, which we take for granted. This video was very educational indeed.
Very cool. And I like the music you made for it. A man of many talents! The only tower clock I was ever in was the one at the Potter County courthouse in Coudersport, Pennsylvania. I went up with the fellow who winds it once a week (cold that day!) and I got to speak with the old gentleman in town who restored the clock. Fascinating! And addicting!
@NativePrairieWolf Thanks for your comment. I'm thinking about doing more. I like your videos about leg traps. I enjoy hiking off trail and I'm always worried about these things.
@TheProfessionalMom I'm glad you liked it. I checked out some of your music education videos and I'm impressed with your work as well. My son is interested in violin. Having seen your video, we are inspired to press forward boldly.
1.34 By a hand crank you lift many kilo so by using hydraulic we can lift many tonnes of load We use the hydraulic to turn the hand crank 😅😅😅😅😅😅 So we got our hand powered power house Keep talking
Last year I had the pleasure of getting a tour of my university's clocktower. Still a full mechanical system like this one, in a non-climate-controlled tower. It's wound and adjusted twice a week.
Great video Trevor. I have seen that church but never got to the clock tower. I am a big E. Howard fan. This is a beautiful movement and you should be proud of your work maintaining it.
@murfffster Thanks! The youtube video was completed by a few people. Video filming was done by Tamra Hjermstad and the editing was done by Allison Graebner. Tending to the clock is an intriguing part of my week. I usually bring someone up with me to wind it. Annual maintenance is a big deal and daylight savings time is like the superbowl for me. It is another one of those jobs that few people know about, even though the results of the job are always in plain sight.
Very informative! I always wondered what kept the pendulum swinging. I understood how the pendulum escape mechanism worked but what kept the pendulum swinging? Now, I see!
I have always been wondering you know that dial when you are winding up the clock tower what is that for exactly I know it's not counting for the seconds I've always been thinking it's for telling the time?
Gotta say...great vid! Those cut pinions must be given extra care unless tightly protected from dust and the application of 'giftings' from pidgeons and etc. First time i have heard pallets called horns, although the resemblance here is a bit true. E. Howard was certainly a very fine clock maker.
At 1:22 I can clearly see the maintaining power 'funktion' on the weight wheel. If the 'small' spring on this wheel is missing then the clock will run backwards when you wind it up for sure. But a maintaining power is created therefore, that the clock coninues running further while the winding progress.
Wenn man beim Aufziehen der Uhr das Pendel anhält und nach dem Aufziehen wieder anstößt dann hat die Uhr in paar Sekunden. Hier wäre ein Gegengesperr gut damit das Gehwerk der Uhr beim Aufziehehen nicht unterbrochen werden würde.
I like to think I am a time thief during daylight savings time in the spring. I steel an hour from everyone's sleep in the night. Honestly though, I can look right through the window in the clock face and I will see more people looking down at their phones than up at the clock. It is a different era.
I like the video, easy to understand. There are only 4 wheels in this movement, in a watch movement are 5 including the escapement wheel. Is this correct? Great wheel Centre wheel (universal link to the dials) Intermediate wheel Escapement wheel
Thanks. Interesting to see a modern clock. The only other tower clock I have seen is from about 1660. About maintaining power (sustainer?). I hang a small weight on the second wheel of my home made clock when winding it. If I forget to remove it, it will just fall on the floor after a few minutes.
Well done! So, in winter the extra friction slows the mechanism but a the same time decreases the pendulum length which quickens the speed. Do they cancel each other out?
It is pretty big, especially when you compare it with a grandfather clock or a mantle clock and you see the tiny escapement wheels they have. I figure I could get my finger stuck in the escapement if I tried. Fortunately, I have always had second thoughts about that.
Trevor, this video is fantastic. One question; you said around the 3:36 mark that driving the hands required 48 lbs. Was that foot-pounds or inch-pounds?
I have that very same clock, but without the cool option of the local setting clock face. I've worked on a few Howards back in the 70's and early 80's. Too old now to climb the stairs.
Hi, I really liked your video, it was very helpful. I'm going to work (for a school proyect) with a mechanical pendulum clock, and I was wondering if you can recommend me some books (that I can study) about how the mechanical pendulum clock works. Thank you very much :)
When I'm winding the clock the escapement wheel floats as the anchor horns jab into it. It might be fine, but power is not maintained. I should video tape it so you can see it and tell me what you think. I rather stop the clock than allow uncontrolled behavior of the anchor escapement.
Do you think there is a way to manipulate a tower clock in order to "gain" an extra 10 minutes within a given hour? But only in one specific hour? Haha, sorry for the weird question but I am asking because I am working on a story where a group of school kids want to manipulate a tower clock.
I am not sure how to make that happen. You can slow the whole thing down, or the hands can get stuck on the numbers. You can put the hands on in a way that doesn't make sense (hour hand on 12, but minute hand on 30). You can add lots of gum to the top of the pendulum bob making it go faster. You can make it go faster by making it colder. The pendulum shrinks because of cold.
After watching your two videos, I still don't understand how two parts of the mechanism work. The reset mechanism... How does it work such that it doesn't disrupt the clock when you reset the weight? The output mechanism... The three needles are on the same axis, but move at different speeds, do they use... hollow axles or something? Like... the second hand uses the innermost axle, then the minute hand use the middle one, and the hour hand the outermost one?
+Anonymous71475 We don't have a second hand. You are right that an inner axle does the minute hand. The hour hand is on the outside and slowed down with gears. I think I have that right. As for the weight, there is always weight pulling and powering the clock as I wind it. The ratchet keeps tension through the whole process. I used to stop the clock when I winded it, but it turns out not to be so important. The reason I would stop the clock was that I saw the anchor escapement float a bit as I wound the clock indicating less tension. I think the power is less, but sufficient. The winding does not take that long.
Weight driven clocks require a form of maintaining power to ensure power is still available to the going train whilst winding takes place. See this article for more information.... en.wikipedia.org/wiki/Maintaining_power
Great video - really informative. What I wonder is how much do the indicator hands weigh - especially the longer minute hand(s) - and why don't they affect the running clock speed i.e. run faster from 12 to 6 and slower vice-versa? Are there counterweights for them?
I never thought that with 4 dials you would need a gearbox and 4 driveshafts. And a smaller clock inside mated to the big clocks so you can set the time. May this beauty live forever...love it!

Good call... Motor heads with cars always talk about torque. As you, and I know, HP, or weights for a tower clock, make the world go round.
Thanks
This clock is great and I loved watching you wind up the weight.
Correction...the axle shafts have about the same amount of power each...except for friction loss. The power goes as Torgue x Angular Speed. Each shaft has differing torques and speeds. In inverse proportions.
Thank you for showing the workings of a pendulum clock.
Amazing that it is so simple.
So superlative and educative video. Thank you from Patagonia, Argentina!!!
Wow! My son has a recent fascination with gears, and he was riveted by this video. I was too! Thank you for a wonderful TH-cam field trip.
An excellent video on all counts. Beautifully photographed and described. Congratulations to all concerned.
Great walkthrough on a beautiful clock tower. Very cool! Thank you.
I`ve made a few wooden clocks in the last year or so, its amazing the similarities in the mechanisms of mechanical clocks, right up to tower clocks,
A very interesting video. I am fascinated with mechanical clocks of many varieties. It was a treat to see inside a large-scale work of art such as this. Thanks for posting!!
If I could buy an old chapel with a tower clock and a tracker pipe organ I'd be in "heaven". Great vid and thanks for sharing!

Great instructional video. Amazing that the distance of the pendulum creates the length of the second tick. Weighted Pendulum Power!
@OldTimerGuy58 I'll check on the escapement. It was due for oiling when we made the video. Thanks.
Very fascinating! Thanks for sharing. What an honor to be the timekeeper :)
Very informative! I always wondered what kept the pendulum swinging. I understood how the pendulum escape mechanism worked but what kept the pendulum swinging? Now, I see!

Brilliant engineering and art
Hi am a Gambian, wishing to recycle our Churche's tower clock, which seized to function since early 70s
@clockguy2 Thank you. Your videos are great. The clock and bells at St. Michael's are fascinating.
Gotta say...great vid! Those cut pinions must be given extra care unless tightly protected from dust and the application of 'giftings' from pidgeons and etc.
First time i have heard pallets called horns, although the resemblance here is a bit true. E. Howard was certainly a very fine clock maker.
Thank you very much for this video it was very interesting. I have always had a fascination with clock mechanisms especially the large tower clocks.
Sure wish my Dad was alive to see this video. He loved his clocks.
MartyLJ57, Thanks so much for your comment and I'm glad to have brought you some memories.
Wow my father was also specialist in this field from pakistan he dies in 2002
Marty Jeruzal I am sorry for your loss T_T
Mans ingenuity in the last 2 hundreds years is amazing. However, The Romans were pretty great as well.
Really interesting, always been curious

Why do you have to stop the clock while winding it up, if the clock's got a maintaining power?
2:52 the final pinion shows visible wear, in my opinion.

Correct. Generally there are counter weights on the shafts to create a stable balanced force.
Thank you

Thanks! That was intresting.
