Description: |
| "One important object of my improvements is to facilitate the bending of the rims of piano-frames upon a short radius, and I have therefore devised links of tapering form, the narrower ends of which are hooked on the pins which pass transversely through the templet, while the larger ends embrace the screw-clamp bar."The inventor was a co-founder of Steinway & Sons. |
