Does anybody know the dimensions of the little wig wag device that trips the clock pendulum action? The one on the clock is damaged and reproducing the part will be a lot easier it somebody has a photo or dimensions I can use.

Thank You

Rodarte3 has indicated it's not the same as I posted. I have included a low resolution image of what he sent to me.
I can forward a higher res image if needed.
If anyone has the dimensions for this toggle or a better image let me or Rodarte3 (John) know.
It does look to me though that this part is salvageable, just wick off all that solder and crisp up the "Vee" edge.

I presume John you understand the "wig-wag" or "toggle" as in "Hipp toggle" named after the designer, is brushed past by the pendulum. When the arc of the pendulum swing is not sufficient for the pendulum to brush past the toggle what happens is the stiff upright on the pendulum (seen just below the toggle in the image) snags in the "Vee" of the toggle. When it snags in the V it starts a series of events that ultimately results in the pendulum getting whacked to increase the arc of swing allowing the pendulum to brush past the toggle again.. Noisy , clumsy clocks.

Thanks, I didn't know the exact name of the device until now.

The Hipp toggle you see was an empirically engineered device based on the observed operation of the clock. It has been working so far so I may have stumbled onto a device similar to the original. I'll clean it up hopefully it'll be ok. And yes it is a clunky design and my expectations for accurate performance is limited but it is an interesting clock.

Thanks again Ray

John,
The material and photos I sent to you are the style toggle shown in Ray's drawing. I think that operation should be the same for both styles. I mailed the article on Poole/Barr clocks and a few more photos of the Barr Clock on a CD yesterday.
Please let us know how you come out.
