ABSTRACT:
A fluid directing means is described that can be used with a conventional garden hose or connected directly to a water tap for applying a linear array of water across a work piece such as an automobile, undergoing repair. The linear array of water consisting essentially of side-by-side streams of water emitted from a flexible hose closed at a far wall and having a series of openings along a segment of its side wall. Because of the size, shape and orientation of the openings, there is sufficient volume of water to facilitate the shaping, smoothing and polishing of the damaged area without undue waste. In addition, a series of non-marring suction cups are provided. The cups are oriented so that the working edge of each cup define a suction plane normal to the axis of symmetry of each opening. In one arrangement, the array of openings directs the streams of water from an essentially common height above the earth's surface at a maximum impact angle (90 degrees). In another arrangement, the array is sinusoidally positioned so that there is an increase in the volume of water per unit length without need to vary the volume entering the hose. Also since the cups are attached by suction alone, they can be easily re-arranged as required.
