The Talking Machine Forum — For All Antique Phonographs & Recordings

We have heard of self winding watches, I am wondering if anyone has seen a motor that self winds, I think it is possible, a gear could be winding the springs as it plays for continued power. Just wondering if this was ever done.

NO ! Perpetual motion you have invented just and exists it not ! Watches wind because the wearer moves and a weight moves as the` wearer moves , Winding Thus !

could we put a small one on our wrist to self wind? Just kiding i have several self winding watches and you can feel the movement of the weight when you move your wrist around. I believe the motor on the machine would wind the other until they equalized then it would stop so no gain just a pain

Actually something like this was created back in the 17th-18ths centuries to help get watches and clocks to run more consistently...


Google "fusee`"...

BUT you still need to wind a fusee movement , NO ? Nothing in nothing out !

maybe a system like in the Lecoultre Atmos clocks? I doubt it would be powerful enough for phonograph applications unless afeatherlight electric pick-up is used?
anyways it would be extremely expensive to build and quite useless.

True. Just suggesting that historically, there was a device that somewhat embraced this premise.


You are correct, Soundgen, they all require some sort of energy input to get things rolling.


The problem of using the running machine to wind its own / another spring is that eventually, it will achieve a balance between the two, and there will be no more transfer of energy, eg: everything comes to a halt.

It is possible to wind a clock using changes in atmospheric pressure, but that is only possible because a clock runs very slowly (1 RPM) and that motor does very little work.

yes you do I have a fusee pocket watch it has a chain drive other than that same has a regular movement except for a second hand but I haven't looked at it in a while I use to collect watches
