To do this fit the organ pipe with a movable stop, or push, which slides in and out of the pipe. Make this push of two strips of ¹⁄₈ inch thick wood, 2¹⁄₂ inches wide and 12 inches long; screw one end of each of these boards to a block of wood the size of the top of the organ pipe and screw a knob—the head of a clothespin will do—on it in the center for a handle. The stop, or slide, will of course be open on two sides and must slip snugly but easily in the pipe.
To Play the Push Pipe.
—If now you will blow through the mouthpiece and slide the stop in and out various tones and semi-tones will be produced. It takes very little practice to learn just where to stop the slide to make a given note—that is if you are at all apt in playing musical instruments. A push pipe[111] is just the thing for a black-face musical act.
[111] A push pipe can be bought for $4.00 of the L. E. Knott Apparatus Co., Boston, Mass.
