Abstract
A vertical hollow cylinder is closed at its upper end, open at its lower end, and has a hole in the cylinder wall. First and second vertical parallel posts are secured to the upper end of the cylinder and extend downwardly inside the cylinder on opposite sides of the hole. The posts are adjacent the hole and are disposed adjacent but spaced apart from the inner surface of the cylinder wall. A vertical hollow cylindrical member is disposed rotatably within the first cylinder and has an open lower end, the cylinder and member having a common vertical axis. A flat circular disc is secured to and closes the upper end of the member, the center of the disc being aligned with the common axis, the disc having an off center opening and being provided with a vertical upwardly extending peripheral lip which extends partially around the disc. The disc is disposed within the first cylinder in such manner that the lip extends rotatably between the inner surface of the cylinder and both posts. A short vertical hollow tube open at both ends has its lower end flush with the opening in the disc and extends upwardly from the disc. An elongated hollow nozzle having a vertical discharge port at one end…
