Abstract
In a carillon or chimes keyboard, which may be a manual or a pedal set, the eys (sticks or pedals) and the frame for taking them up pivotally are provided with cooperating surfaces, one surface on the key hitting the other surface on the frame at the end of the upward release movement of the key after it has been depressed for operating a bell. For dampening the clattering noise caused by this hitting, the invention provides for such cooperating surfaces on the keys and the frame, which are inclined, preferably at about 30.degree., to the upward direction of movement of the keys just before they hit on the frame during this release movement.
