8765. Dickinson, J. H. April 15. Automatic instruments; organs.- The invention relates to a vacuum tension regulator. The port e leads to the bellows and the port f to the action. The regulator consists of a bellows A distended by a spring B and carrying on its fixed side a a valve seat g, on which a plate C pivoted at one end turns. The other end of the plate is linked to the movable board b, and it is thus enabled to open and close a port h. The port is oblong, its longer dimension being parallel to the board a.
