I am working on a Japy countwheel strike movement with a missing suspension spring and some of the regulator adjusting parts. The regulator is not a Brocot or a Vallet type but a Duvoye type. Anyone have parts or photos/diagrams to assist in fabrication?

Hey Ajs-

All I could find on the Duvoye suspension was in "The French Marble Clock" by Nicolas Thorpe, pg. 89. There's no photo but here's what it says...

"The Duvoye suspension is in many respects a cross between a Brocot and a Vallet versions. The name 'Duvoye' appears on the adjusting wheel. I first saw it used on a Japy locking plate movement that was manufactured after 1880. Duvoye lodged a patent for a type of clock suspension in 1852."

It may be possible to find the original patent information based on the above information.

A Google search for "Duvoye" turned up some photos Here. They may not be detailed enough to help with your reconstruction but at least they are photos :).

Hope that helps!

Hi David,

There seems to be a problem with your "here" link. It looks like the Seth Thomas Fly photo from a few days ago.....

Best,

Richard T.

Thank you that is the closest I've seen yet. I would love to see the original patent drawings.
