Can you figure out what this does?

[Clark Sprague]

Paul,  I have seen a mechanism similar to this on an old AB Chase that I did some restoration on.  I think it was a compensator for lost motion when the pedal that raises the rest rail is engaged.  I didn't experiment with it enough to be sure, though.

  Below, and attached, is a picture of a whippen from a Chickering Bros (ugh) grand. It's the kind with a soft pedal mechanism that raises the hammer rest rail closer to the strings to reduce blow distance.

  Familiar to anyone?
