A mechanism without any known practical purpose. I originally sketched it out 34 years ago as a 17 year old boy. Somehow, building the device got put off unitl now.

  • can you explain how it works? my 8 yr old and i are interested

  • The weight (paint can) is connected to the pinwheel by a string wrapped around the pinwheel axle. This turns the pinwheel as the paint can drops. The pawls (bent wire parts) alternately engage the pins, causing the flywheel to spin one way and then the other. The energy in the flywheel causes the pinwheel to recoil at the beginning of the engagement (locking) of the next pawl. The recoil causes the other pawl to unlock, and the cycle continues until the can reaches the floor.

  • Thank you dear, I know I can always rely on you for an unbiased point of view.

  • This escapement is amazing! You were 17? You was smart boy!

  • dam that was LAMEEEE

  • Good thing you got around to making this device. It's very interesting that it changes directions. This mechanism could actually be used for many purposes, for one thing it has reciprocating movement. If you have some drawings please send them to me, see if we can come up with a practical use for the device.

  • do you have more stuff from when you was 17 years old???

  • I like stuff like that, kinetic sculpture can be anything add some wind chimes and some mirrors to throw light around the room and it would be musical and optical.

    The possibility is endless.

    Looks good so far, an artist never feels his work is DONE.

  • Seems to me it would keep relatively decent time, except it's movement is plowing thru a lot of air and thus would be more sensitive to humidity, temp, and so on. It would still be nice to see the correct ratio of gears for the escapement timing to turn some clock hands. Would like to see that too. Who really cares if it can keep super accurate time. I'm just guessing that 90% of folks are within 10 seconds of knowing perfect time with cell phones and such at their disposal. Thanks for posting.

  • Well, I think this is pretty cool. It may not serve a practical function, but it is nicely built and interesting to watch. Well done.

  • stupid

  • That is amazing. And you doodled this when you were 17? The part where the recoil causes the pawls to unlock is beautiful. I bet if you adjust the weight's mass and the flywheel you could get a regular timing out of it and make a nice kintic sculpture clock. Dammit, now I want to build one!

  • BTW adjusting the weight on the "flywheel" can be used to adjust speed two. Smaller flywheel gives more acceleration. Bigger less.
