. Appleton's dictionary of machines, mechanics, engine-work, and engineering. huttle. The spout lias thus theoutline of a truncated pyramid, of which the faces converge towards the extremity at an angle of 6 to7 degrees with the axis, directed towards the superior surface of the start of the bucket im-mediately in advance of it. The direction of the current upon the wheel is thus preserved under anyvariations of head-pressure upon the shuttle ; and the impulse being directed as nearly as possible inthe line of motion of the point impelled, its value becomes an increment to the force of gravity of thewater, and, to some extent, economizes a power which would otherwise act injuriously in projecting thewater beyond the proper range. The horizontal dimension of the orifice, under this arrangement, andespecially when the system of ventilation is incomplete, ought to be a little less than that of the buckets,and the height perpendicular to the axis ought not, in general, to be more than four inches, and it isalmost always better to be less. 3802. 3798.
