Thanks for sharing this. I have been fascinated by clocks since childhood when I took apart a Big Ben windup alarm clock my grandma had. I finally built a simple escapement in Lego (not even Technic parts) and being able to see one operate for myself, based on my own design, was a real turning point. I've collected clocks since, and built a couple, even. I may build you simple escapement to show my own kids how the mechanical clocks we have around work.
Bruce, I am sure you know that you inspire some of your students to take the next step in their lives to explore the made universe.I had a teacher like you for two years in highschool , he had your ability to get me to look at how physics work. Unfortunately the school had a commercial/ academic bent so I only had him for one class once a week. Thankyou so much.
Thank you, I hope that has been the case. I've found it interesting in talking to several former students that many of them wished that they had me at a later time in their schooling rather than in middle school. They think they might have appreciated it a bit more when they were a bit more mature.
@@YeanyScience Thankyou for your kind thoughts. As achild I was interested in machines and tools and stuff, working alongside my dad. I wanted to do a trade at 15 but my parents didnt want me to end up in a factory. They were post war migrants from Germany and they saw my future in something more academic. I ended up working in a bank for only a very short time then took up truck driving from which I am now retired. But that job didnt require much brainpower so I used the day thinking of things I might do in my spare time. I am now an inveterate tinkerer and love to see the things you do and the inspiration you give to your students. If your work gives one kid in ten a spark of knowledge then you have succeeded in your life's purpose as a teacher. .. 20 yrs. ago here in Australia the state government closed down all the technical schools which used to take all those no hoper kids who werent academic and turned them into useful, productive members of society. Today they are pouring all the kids into University and they all come out at 20 years of age with the same degrees or diplomas and no practical work for them. Look on YT how many young people are seeking knowledge in the crafts and trades that no longer exist commercially and they make a damn good go of it, perhaps from the little light you and other teachers like you switched on for them. Cheers , from Melbourne Australia
Excellent description of all the mechanisms at work, I especially loved how you broke down each mechanism and how they all operate in tandem to make more complex movements. I wish I had a teacher like Mr. Yeany when I was still in school, it's clear that he goes above and beyond to make educational information more accessible and enjoyable to novices. I just discovered this channel and I've already subscribed, I look forward to future videos on similar topics in the future!
The greatest hits flash backs at the end were so fun! Brought back a lot of good memories of your fun channel and doing many of these experiments (I so kindly borrowed) from you in the classroom.
Gravity powered escapement wheels have been around for centuries, The grandfather clocks imported to the colonies, like the one my great grandparents had when we were kids in the 1930s & 40s, were powered with weights which were usually rewound daily. The clock mechanism, including the escapement gearing, was virtually identical to that of a coiled spring powered clock, except the energy was stored in the weight on the end of a rope/string wound onto a "drum". Part of the escapement mechanism was the pendulum, which served the same function as the escapement wheel spring in a spring powered watch or clock. The distance from the pendulum pivot to the center of its weight determines the period for the escapement cycle.
@@YeanyScience I saw that! I'll be watching for it. Have really fallen down the YT rabbithole on the subject already. Biggest problems I've encountered so far involve efficient fastening methods that don't introduce too much friction.
Thoroughly enjoy this one sir thank you! I would love to know if there was a set of plans for that, it would be a lot of fun to make with the kids. Make On
I love this!!!! I've been tinkering with old clocks, and I decided I wanted to make one. I have the best skills with wood, so I figured, why not make a wooden one! I love seeing easy to look at and understand examples of the parts I may need to build. My question is - What's the best way to cut parts like this? Bandsaw? Scroll saw? Please let us know what tools you found the easiest to work with. Thanks! 🙏 ~ Josh
Please Bruce teach me how to build one!! It would be a great quarantine project, some vector files to print and glue to wooden boards to cut would be amazing. Great video
Awesome video, Professor! You can also use a planet gear as an escapement, which has the additional benefit controlled, continuous output to drive things like little handlight generators, too. Cheers!
Could you provide plans for the escapement wheel and maybe even the other simple machines and devices? Your videos seem like an excellent resource for teachers and plans would make them even more invaluable to some that are perhaps not as resourceful.
on the turning wheel just add 12 small neodymium magnets and have it run across some coils of wire. try to get 12 volts and put that 12 volts into an inverter to power things.
Physically not possible. Say if the weight is moving down at 1 cm/s and is about 1Kg, it produces 9.81m/s^2 * 1Kg * 0.01m/s = 0.0981W of power. ~100mW is probably enough to light an LED but that's about it
Tough question, most of pieces I've built were done for educational purposes. With some pieces the ideas came from wanting a way to demonstrate a particular concept. I've spent a lot of time in science museums, looking at other peoples' work in books, online, etc, and then looked for ways that I could simplify it or change it to suit what I wanted. In this case I've seen quite a few variations of escapement wheels and wanted to try one for myself. What was interesting was about 3/4 of the way through building this piece I found someone's else's design that was very close to what I was working on, if I had seen it sooner, copying their piece would have been a lot easier but also less of a learning experience
that's what I was aiming for, I have several mechanical clocks around and were always fascinated by their movements, I wanted to show it on a simpler scale
i only see the forces of the weight turning the the wheel the with the teeth. i dont see how that wheel with the teeth is helping to move the pendulum or the wheel at the top its attached to
i bet you could attach a tiny generator and get it to light up an LED. You might need to scale up some of the pieces to get enough torque to generate power but I bet you could do it.
yes, that is why there are two strings supporting the driving weight, giving it double the run time. If I doubled them again it would halve the travel again. I figure the way it is set up now runs long enough as a demonstration piece.
Hey I just found your video and went on to try to make one myself but I can't get it to work properly. So do you by any chance have some tips or tricks for tweaking my design?
This reminds me of something which takes into account Newton's Third Law of Motion. Have you seen those alarm clocks which are wound using only one key? I realized that the way such clocks work relies on the fact that you cannot put tension on one end of a spring without putting equal and opposite tension on the other end. This says that both ends of the spring can be used to provide potential energy. So, when you wind up a single-wound alarm clock, the "wrong" end of the torsional spring powers the clock movement while the winding end powers the alarm movement. That's killing two birds with one stone. Simple!
Bruce, please add a device to this latest project that ensures the wheel can turn only in one direction. This is a question I've always had: how did an engineer ensure that a steam locomotive's pistons were driving the wheels in the same and correct direction?
Quite a conundrum. I don't think anyone built a single cylinder loco, there's at least two. If these are coupled (via the axle on the drive wheels) you can build the machine with a 90 degree phase relation between the two. That solves the problem. For a single cylinder you can either kickstart the flywheel in the desired direction or very gently let it run backwards part of a turn and then slam the breaks on and restart. I think the latter was done for some giant beam engines. Not easy to kick start a 200 ton flywheel! I think the pumping station I visited had a smaller engine as a "starter motor".
If the 2nd law of thermodynamics and every other physical factor that can slow down and eventually stop the thing is ignored can this machine go on forever?
5 24 Make something which contains many kilowatt hours energy if we use a hydraulic jack for winding up the spring and a dynamo give energy for 12 hours easily 50 hz 250 volt 16 amp So energy crisis become equal

Looks like it would be fun to make. Unlike most woodworkers I haven't been doing much woodworking during the quarantine. I should get back to my shop.

Hello from Brazil o/ very interesting videos :0

can you make another escapement wheel connected with another escapement wheel in series?
Would it be possible for you to send the measurements of each part?

i only see the forces of the weight turning the the wheel the with the teeth. i dont see how that wheel with the teeth is helping to move the pendulum or the wheel at the top its attached to
Yes. But how well does it work at sea?
5:15 Well that is nightmare fuel.
What about an escapement generator to produce electricity ?
On a larger scale ?
Good idea ! Where the energy source can be the difference in water level of the tides, for example.
Good
Muy bueno
Mr.Bruce this is beautiful craftsmanship. I would love to build this.. is there anyway I could get the plans to this? Thank you sir for this video..
Hi John, I'm working on a follow- up video going over the construction that will be posted in a few days
What is the importance of the big wheel in the upper of the board, and thanks
I wanted something more than just the pendulum swinging back and forth, in the future I plan to add additional movements
@@YeanyScience ok👍, thank you for your big effort to learn people💙😊
i bet you could attach a tiny generator and get it to light up an LED.
You might need to scale up some of the pieces to get enough torque to generate power but I bet you could do it.
Yea, it would be fun to see how much electricity it can generate.
How could you make it quieter?
we can use axle with the screw wheel instead of string!
yes, this was a first build and tried to keep it fairly simple, now that it works I have plans to add more to it
Tie a string to a water bucket perched over a bed and this would make an effective alarm clock for parents.
Hi
Hello sir. Did you invent this design or used another? if you used another, what is the design called? thanks and God bless!
Is it possible to buy this ?
Hi Bruce, do you have plans drawn out for this? I want to replicate it.
I am working on a better version and hope to post it with some free plans this summer
Please correct me if I am wrong! If you double the weight, and double the pulleys, the pulling power would stay the same, but halving the travel?
yes, that is why there are two strings supporting the driving weight, giving it double the run time. If I doubled them again it would halve the travel again. I figure the way it is set up now runs long enough as a demonstration piece.
Could an Escapement be used as a Bicycle Assist?
It makes me think of the things that musicians keep on top of a piano to keep time.
1:00 omg that clock needs a service badly
Hey I just found your video and went on to try to make one myself but I can't get it to work properly. So do you by any chance have some tips or tricks for tweaking my design?
