Total Claims: 4
Claim 1
Independent Claim
244 words
A one-piece nozzle for an architectural fountain, comprising; a body having an internal cavity with a central axis, an inlet port entering said cavity, an outlet port exiting said cavity, both being axially aligned on said axis, said cavity being bounded by a first pair and a second pair of walls, the walls of each pair facing one another across said axis and being mirror images of each other, said walls being generally aligned with respective planes that are normal to one another; said first pair of walls each having an initial portion at the inlet port which centrally narrows and tapers inwardly toward said central axis as it extends away from said inlet port, with a flat boundary at each side thereof, a substantially planar central portion, and an exit portion on the opposite side of the central portion from the initial portion, said exit portion at its center widening and tapering away from said central portion and said central axis; said second pair of walls joining the members of the first pair to enclose the cavity, diverging away from the central axis as they extend away from said inlet port; and a pair of flat terminal walls substantially normal to said central axis, each extending from a respective one of the walls of said second pair, and joining to both of the walls of said first pair, and having edges which, with the edge of the exit portion form said outlet port.
