A spout for providing a flow of water in the form of a sheet is disclosed. Water from a supply pipe is diverted orthogonally in two directions as it enters a reservoir inside the spout. Water pooled in the reservoir spills over a weir to form a sheet-shaped flow stream as it flows down the weir. The weir has a raised center section which helps define a flow chamber to promote and develop a stream which maintains a sheet shape even relatively great distances from the spout.

A waterflow spout of the type having an inlet for admitting a flow of water, a flow chamber downstream of the inlet and an elongated outlet downstream of the flow chamber for permitting the water to exit the spout, the flow chamber defining a passageway for water movement from said inlet to said outlet, the improvement wherein: the flow chamber has a elongated crest downstream of the inlet and upstream of the outlet and said flow chamber slopes downwardly and diverges in the downstream direction from the crest toward the outlet; the flow chamber has a center section and side sections, said center section being arcuate in each of two orthogonal directions, the center section being narrower top to bottom than the side sections and diverging in width in the direction of flow, wherein one of said two orthogonal directions is in the direction of flow and the other of said directions is transverse to the direction of flow, a first radius defines the center section in the flow direction to be concave up, and a second radius defines the center section in the transverse direction to be convex up; the flow chamber is defined at least in part by upper and lower flow surfaces which converge toward one another, at least one of said flow surfaces having a central section which is raised relative to side sections of the flow surface and said raised portion diverges in width in the direction of fluid flow to define in part the center section of the flow chamber; the raised central section of at least one of the flow surfaces is adjacent to the outlet to define the outlet narrower in the center than at the sides; and whereby the narrowing of the center section of the flow chamber and the center of the outlet assists in inhibiting the water exiting the outlet from collapsing toward the center of the water stream to maintain the exiting water in a continuous sheet shape for a distance outside of the spout.
