Steingraeber factory pictures, bridge agraffes & adjustable vertical hitchpins

[Calin Tantareanu]

Hello Yoshi!
 
The Paulello agraffes are not exactly like the Steingraeber ones, as Richard
explained. They are both touching the string in 3 points, but the string
bearing on them is reversed.
In the Steingraeber the string (as seen from the speaking length) bears
frist downward on the front agraffe edge, then upward on the pin that locks
the strings, and then downward again on the on the back agraffe edge.
In the Paulello agraffes, the strings bear first upwards on those holes,
then downwards on the round pin, and upwards again on the holes to the rear.
I have never played a Paulello piano, so i can't comment on how his agraffes
work. But I would expect an effect quite similar to the ones used by
Steingraeber.
 
Regards,

Thanks for the detailed report and the pictures. The bridge agraffes and the
vertical hitch pins exactly look like Stephen Paulello's piano (attached). I
wonder if Steingraeber acquired his idea.
