This clock is in for repair in Norm's shop. I don't know what the case looks like, but the elegant simplicity of this clock is just outstanding.

The pinwheel escapement - beautiful in its simplicity.

Elegant dial with sweep second hand. Nice detail on the bezel.

Is that called a "Grasshopper Escapement"?
Very elegant!

Hello Tom
It looks like the bob is hanging from 9 rods. Do you know if they are brass and steel, every other one? And they are round, not oval?

That is called a Pinwheel escapement. If the pendulum rod is original, it will be alternating metals to comensate for the temperature change. I have never seen a pinwheel marked as to maker.

Here is another Pinwheel Escapement movement. A little dirty before cleaning. Looks to be a little more robust built.

Greg, This is not the "grasshopper" escapement. I will post drawings of both. They do have some elements that look similar.

This is the Grasshopper Escapement.

Gary, It is an alternating brass and steel temperature compensating pendulum. The rods are round not oval.

Hi Tom
I thought they looked brass and steel but wanted to know for sure. The picture I posted is out of a standing Waterbury Hall clock. This movement also has steel and brass rods but they are oval. I have been told Waterbury clocks are the only ones that have the oval rods. Have you ever heard the same?

I am repairing a pinwheel clock that is almost identical to the one postec by Tom Seymore. Do you know its maker?

Those are very nice and unique clocks. I really like the pin wheel escapement and the clock in Tom's posting is so nice and simple. That is the attraction to it for myself.

There are other movements that are quite complex and difficult to understand. How would you like to repair one of the difficult ones? But again the simplicity is just plain elegant.

These two clocks are great postings guys.
