STEINWAY CONCERT GRAND PIANO PATENT PRINT FROM 1880 This patent print is taken from an original application by C.F. Theodor Steinway, dated May 28th. 1872. The patent was granted on October 26th. 1880. An extract from the application reads: "These improvements relate, first, to the construction of the bottom or bed-plate of the case; secondly, to the construction of the metal frame; thirdly, the mode of supporting the metallic frame, whereby a larger area of the sounding-board is left uncovered and the metal frame is kept out of contact with the sounding-board, and hence does not interfere with its freedom of vibration; fourthly, to a mode of combining the metal frame with the wooden frame of a piano, whereby the wooden frame is made to contribute to the rigidity of the iron frame; fifthly, to the combination, with the iron frame, of a metallic wedge or stretcher which may be removed for the purpose of allowing free access to the iron frame for the application of the treble-strings, and may be afterward inserted for the purpose of strengthening the iron frame and increasing its capacity to resist the pull of the strings.".
