The combining tube is made free to slide in the direction of the axis of the tube and is adjusted by a hand wheel at the side of the injector, the shaft of which projects into the injector and carries a small pinion that meshes with a short rack formed on the tube. Packing around the sliding tube is dispensed with by forming the tube in two parts, a fixed part and a sliding part, and proportioning the two parts so that the ends of the sliding part will be \u00e2\u0080\u009copposite that part of the passing current where it has attained its highest velocity; and by this arrangement the passing liquid has no tendency to escape but rather to draw in air or fluid.\u00e2\u0080\u009d"}, {"label": "Description", "content": "Reference:"}, {"label": "Description", "content": "This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A.
