Title: Squat-type water closet
Claims: What is claimed is: 1. A squat-type water closet for installation in and substantially level with a floor and providing at the floor surface an elongated opening, comprising: a bowl member having a waste outlet or discharge opening from the bowl bottom and having a discharge connection formation for connecting to a soil line, a bottom sloping downwardly inwardly and from front to back to the outlet, outwardly extending horizontal flange means for bowl-supportive engagement with environmental structure, and an integral flange having on its top region an upraised peripherally continuous seat formation, a flushing rim member having its outer periphery complementarily shaped and sloped to be matingly received within said seat formation continuous with a seal interposed between said rim member and seat formation to define the effective top opening of the water closet, and said flushing rim member being downwardly open and cooperating with the bowl member top region to form a flush water passageway and defining with the top margin of the bowl opening a slot substantially continuous about the bowl top periphery to discharge water in a substantially peripherally continuous sheet down the bowl inside surface for flushing the bowl interior, a flushing water supply connection integrally formed on one of said members providing an inlet to said flush water distribution passageway, said flushing water supply connection communicating with said flush water passage through an inlet-restricting orifice at one end of the closet whereby to increase the velocity of said flush water in said passage, one of said members supporting a V-shaped divider baffle with vertical apical edge aligned with the orifice axis for dividing incoming flushing water to flow bilaterally down the passageway along each side of the water closet, and means for securing said flushing rim member sealed to the seat formation on the bowl. 2. A squat-type water closet as described in claim 1, wherein said slot, to insure flushing water distribution, constitutes a discharge flow restriction symmetrically decreasing from the inlet orifice toward the remote end of the bowl. 3. A squat-type water closet as described in claim 1 especially adapted for installation in a poured concrete slab floor having a closet-receiving opening, wherein said members are rigid metal castings, and said flange means includes a continuous seal seat formed integrally to its top side to provide said seat surface. 4. The water closet of claim 3, wherein said bowl member is cast with its said seat spaced out from and sloping toward the bowl top opening, and said rim member being secured on the top of the bowl by bolts located externally of the seats. 5. The water closet of claim 3, wherein the rim member as an integrally-cast structure includes a downwardly-open channel running continuously around the peripheral rim circuit to define with said bowl flange the flush water passage, said supply connection comprising a threaded opening at the rim back end communicating with said flush water passage, and said water outlet being at the rearmost portion of said bowl bottom and defining the lowermost portion thereof. 6. A squat-type water closet as described in claim 3, wherein said rim member includes a flat visible top surface, and outlines a smoothly rounded keyhole-shaped opening into the water closet bowl, the rim member including apertured outward lugs for securement to the bowl flange by bolt means located below said flat top surface, so that a floor finish structure may be carried level up to the visible top surface of the rim. 7. The water closet of claim 3, with the means securing the rim member to the bowl member comprising an interposed continuous annular sealing gasket, and securing bolts through rim outer lugs into tapped holes in the bowl flange. 8. The water closet of claim 3, wherein said supply connection is at the back region of the water closet and located for connection to a flushing water supply line below floor finish surface level. 9. The water closet of claim 3, wherein the said flange provides an upper surface portion integral with said bowl adapted to receive thereon flashing incorporated in the floor and carried up toward the slab opening; said water closet being provided with means for clamping the flashing margin on the flange; the last said means being disposed entirely below the level of the rim member top to be concealed by the floor finish structure carried in to the rim member upper margin. 10. The water closet of claim 9, wherein the clamping means comprises clamp plate means and bolts through the clamp plate means threaded into integral tapped bosses on the flange. 11. The water closet of claim 5, wherein said rim casting has a rim channel inside wall extension or depending skirt on its inner perimeter to define, relative to the bowl top inside edge, a flush discharge slot increasing in width and decreasing in extension thereby decreasing in flow restricting resistance from the inlet toward the opposite water closet end. 12. A water closet as described in claim 11, wherein the flush discharge slot-defining surface of the rim wall, to either side of the inlet location, terminates downwardly in a substantially angular corner to abate spray from the slot.
