DA Stack Split
By Darrell Clarke, forwarded by Robbie Rhodes

Dan, I was asleep when I suggested that the tubing was displaced! Your explanation of the early Duo-Art split at E/F, as in the Ampico, is quite plausible. But the date of the incident (1914 or earlier) suggests yet another possible explanation:

Mr. Charles F. Stoddard, the Ampico inventor, held several key patents used by Duo-Art, including, I believe, the patent for the accordian-pneumatics used for expression control. One can imagine that Aeolian "hated his guts", but they were powerless until the merger of the two companies in the 1930s, when - some say - the Aeolian management ordered all the Ampico perforators thrown in the river!

Is it possible that, among all the other patents, Stoddard held a patent covering the E/F stack split in a reproducing piano, and that he refused to license it to Duo-Art?
