[pianotech] [Files] Bell upright piano. ("The iron Giant" !)

I find a crochet hook is handy.
You are correct, it is a real pain.

The spring is attached to the jack. The string is attached on the butt
assembly. Various models attach at various points. The one I have, the
string loop is attached just under the butt felt using a slot in the wood
(you have to remove the felt to see it). Another model had a hole right on
top of the butt felt. Then, the loop is passed through the hole in the jack
and hooked on the spring. It's a real pain to get it hooked as you have to
pass a small hook through the hole, grab the loop and push the spring into
the loop. It's also a pain to remove the butt assembly cause you have to
unhook it. Always check to make sure that you have this system as the
whippen assembly won't come off until braking the string or destroying the
spring (how do I know?).

Anyway, the spring / loop action constantly pulls the jack under the butt so
you have a ready to go jack on every repetition. These actions repeat just
as well as most grands.

Thanks

So what does the cord anchor to? I assume the spring anchor to the jack
somewhere, and the cord somehow ties it to the hammer butt?

Marc,
That's the one. For our listees who have not seen this action ---
In your pic the cord looks broken and the spring is pointing toward the let
off screw eye. When the cord is intact the spring runs upward and parallel
to the jack.
Thanks for the picture,
Tom D.


Bell's are usually very nice pianos.

I'm working on one right now. It's has the Illimitable Repeating Action.
I've attached a picture of the jack with a slot in it. It's a real pain to
repair but it does repeat much faster.

One feature I did not notice until today. The jack has a hole in which a
silk cord that is attached to the hammer flange engages a jack mounted
spring. Clear as mud right? I'll try and get a picture.This seems to
duplicate or perhaps augment the jack springs job.
