Abstract
12,129. Riley, W. J., [trading as Yote Manufacturing Co.]. May 16. Drawings to Specification. Actions; transposing-means; blowing and ex hausting air; expression, controlling.-Two sets of tracker-ducts, one for sixty-five note and the other for eighty-eight note tune-sheets with extra perforations for accentuation, are connected by flexible pipes to ports in a double slide-valve, one member of which is movable for connecting either set of ducts to the action, and the other for transposition. The slide-valve also controls means for altering the point of division of the wind chest in accordance with the degree of transposition. For this purpose, a series of partitions is arranged in the wind chest with by-passages controlled by valves operated pneumatically from the slide valve.
