[pianotech] A.B.Chase Grand Piano

[Clark Sprague]

No spring on the knuckle.  The action appears quite serviceable.  I don't know what the other adjustment screw is for, I will investigate next week when I see the piano again.  I will attempt to get some more, and hopefully clearer pictures.
    Jack, I will look at the plate more closely, and report back what I see, and some more pictures, next week.
    Thank you one and all for your comments and insight!  More to come.

Clark

  Interesting knuckle arrangement on your piano Clark. 


  A few better pictures of the arrangement would help also. Is the "knuckle lever" on a spring? 

  There appears to be an adjustment screw going through the rear portion of the repetition lever, just forward of the repetition lever height adjustment screw - it looks like it has a piece of red felt on the top side of the repetition lever and the screw goes through it - picture is fuzzy - what's that all about?


  Pics, pics, pics! Need good clear pics!!!!!!


  Thanks for sharing. Very interesting.

    Happy Thanksgiving to one and all.  We all have something to be thankful for.  These pictures are from the 1890-95 A.B. Chase that I just bought (serial #31241).  This beast is Victorian style, rosewood case (needs veneer repairs), 7 ½  feet long.  The things I noticed were:  the beams underneath are MASSIVE,  and look like oak, the belly rail looks like oak too.  The inner and outer rim are MASSIVE, and it has a beam that runs cross-wise across the width of the piano, about at the midpoint of the soundboard.  The thing has 15 ribs under the board, in a straight array.  The pictures of the knuckle and whippen are an arrangement I have never seen before.  Has anybody else seen this?  The knuckle is a wooden “hump” under the shank, and the interface on the whippen is another lever, on the top of the repetition lever, and the jack lines up underneath that.  Does anyone have an idea what that was all about?  I looked at the bridges, no apparent cracks, and the treble bridge is fairly straight, without any really apparent doglegs.  I think this could be rebuilt and be a whopper piano for someone?  Anybody out there interested?  I haven’t moved it yet, and don’t have any more pictures at this time.  More to come soon, upon request.
