Above left: This Echophone Diatonic accordion was patented by Hans Hohner, a German citizen residing in New York City, on 15 September 1908. Always looking to invent new and useful improvements to accordions, Hans’s invention shown here provided the accordion with a novel and effective means for softening or rounding the tone, and at the same time increasing the power thereof.  The sound waves entered the brass chamber, flowing towards the bulged sound horn.  With the bulged horn, the waves were entrapped and deflected upwardly and emitted through the belled mouth.  The patent was submitted by Hans Hohner in New York City on the 20 May 1908 and approved on the 15 September the same year. Below is the Three Piano Keyboard Patent No. 2,557,690, this extremely rare instrument was an instrument patented by John Reuther as a sister instrument to his Uniform keyboard accordion. Made for a friend of John Reuther’s, Frank Gaviani from St. Louis who had started studying music at an advanced age of 18 years old, the 3-deck keyboard was a one of a kind.  It is a piano accordion with wide black keys and the first row duplicated by the third row.  Frank did not want to alter the order fo the piano keys, but he wanted the advantage of  the third row, and he wanted the advantage of the wide black keys.  Because with the third row, he did not have to get in between the black keys, you could reach above them and interpose with the keys.
