As of January 20, 2014, we are just beginning to collect data about the above named player action. All we have at this point are some pictures of the action and six patents. The pictures were contributed by Randy Suva. The player action is in a Harvard Piano which was made in Cincinnati, OH. The exact year of manufacture is unknown at this time.
A few things about this action are fairly obvious. One, it has a split stack and some form of expression control. Two, it has what appears to be a tracking feature that moves both the music roll and the take-up spool back and forth across a stationary trackerbar. Marks on the trackerbar would seem to indicate that this feature can also be used to transpose the music up or down three notes. There are 88 note holes.
Just below is the listing of the six patents issued to the John Church Co., with a short explanation. Click on the Patent Number to view the PDF file. Once the file is opened, you may save it to your computer, or print a copy for yourself. When you're finished, simply close the window (or tab) to return to this page.
