Does This Mechanism Have A Name?

Knowing that the grandkids were coming for Thanksgiving and that we were likely going to be inside due to the weather, I picked up a piece of walnut from the drying stack and whipped out this little mechanism to maybe occupy a bit of their time, and just maybe make them think about what was involved - relative motion, path defined by the handle, etc, etc. Seems to me that I've seen this diagram before with a name associated, but I can't seem to find it. Thought of a modified Scotch Yoke, but that doesn't seem to be real. Anyway, they thought it was cool for about two minutes, then the electronic games called to them :(:(:(

Yep, it definitely describes an elipse, and that may well be the name of the mechanism.

That mechanism can also draw a horizontal straight line, a vertical straight line or a perfect circle depending on where the 'pen' is attached.

In our neck of the woods something like that is referred to as a furshluginner for a portrazebie.

(Try saying that after a couple of beers!)

Using Mike's link name as a starting point, I found another site that calls the device an Elliptic (or Elliptical) Trammel, and also the Trammel of Archimedes. I think that "Elliptical Trammel" is the name I was trying to recall, and I'm thinking that it was an example in a Mechanism's class many moons ago.

I agree with johnboy, that site Mike posted is a place that eats time. I may have some more mechanism models to make.... ;):D

I wanted to wise crack about the "Many Moons Ago"... But then I remembered your vehicle operation in reverse is suspect and realized you struggle with looking back! :eek:
