Andrew,
I've seen this before, but the only lingering memory is that once =
disassembled it was very hard to re-assemble. Perhaps this was a =
Chickering made on a Tuesday. By the following Monday they probably =
changed the design again :-) Good luck.

  I had a customer bring by the action of the piano he is refinishing.  =
He=20
  wanted me to replace the bridal straps, dampers, etc.  This action =
includes=20
  one very unique feature which I, in my limited experience, (15 years) =
do not=20
  remember seeing before except on a certain west coast action.  There =
is a=20
  spring connecting the jack and hammer butt to speed the return of the =
jack=20
  under the butt.  The spring is about the length and shape of the =
hammer=20
  return spring and it is connected to the butt by means of a silk =
thread=20
  attached behind the jack felt on the butt.  There is also a slot in =
the jack=20
  for the silk to pass through in order to connect to the spring.  At =
the bass=20
  of the jack is a spring tensioner.  The piano is a Chickering Bros. =
(the=20
  Chicago branch of the family) apparently from the early part of the =
century.

  BTW from the best I could tell this system worked as I imagined it was =

  intended to work.  The jack did reset before the hammer returned to a =
full=20
  rest.

  Has anyone seen one of these before?  I have seen a number of =
Chickering=20
  Bros. pianos and they all seem to be well built, often with "unique"=20
  features.  It seems the experimentation bug was genetic.
