  • Patent number: 5944358
    Abstract: In a tub and shower unit, a faucet body 30 facilitates the supply of hot water and cold water either to a tub or a shower head, depending on whether a diverter valve of the unit is set in a tub mode or a shower mode. A reversible ejector tee 82 or 138 is designed for assembly with a center body 84 of the faucet body 30 to insure that hot water and cold water, which is being supplied to the faucet body, will be directed to a spout of the tub when in a tub mode without any water leaking through the shower head. The tee 82 or 138 will facilitate the directing of the water to the shower head when the diverter valve is in a shower mode. The tee 82 or 138 can be reversed in its installed position within the center body 84 to accommodate different orientations of the faucet body 30.

  • Patent number: 5715868
    Abstract: A single-piece tube 20 is formed to include a hub 30 at first end 26 of the tube with a spout 44 extending from the hub to a second 28 of the tube. A tapered transition surface 38 extends between the hub 30 and the spout 44. A bevel 34 is formed at the base of the hub 30 on an outer surface 22 thereof adjacent the end 26 of the tube 20. An annular bead 36 is formed on the outer surface 22 of the hub 30 at a location spaced from the bevel 34 to define a space 46 between the bevel and the bead. A pair of bends 40 and 42 are formed in spaced portions of the spout 44. In another embodiment, an annular groove 50 is formed in the outer surface 22 of the hub 30 instead of the bevel 34 and the bead 36. An O-ring 48 can be located in the space 46 or the groove 50. The single-piece tube 20 formed with the hub 30 and the spout 44 can be assembled with a water mixing facility 56.

  • Patent number: 5566707
    Abstract: A putty plate 30 is formed with an edge 32 in a continuous pattern to define the perimeter of the plate. A base wall of the putty plate 30 includes a floor 40 on one side of the plate 30 and a ceiling 78 on the other side of the plate. Holes 48, 60 and 62 are formed through the base wall. Four sets of ribs 52 are formed integrally from the floor 40 on the one side of the plate 30 while sets of ribs 84 are formed integrally from the ceiling 78 on the other side of the plate. Ribs 46 are formed about the holes 48 in a hexagonal configuration integrally from the floor 40 of the plate 30. Circular ribs 80 are formed about the holes 48 integrally from the ceiling 78 on the other side of the plate 30. A continuous groove 68 is formed in the base wall between the edge 32 and the ceiling 78 to define the perimeter of the ceiling. Two other putty plates 108 and 200 are formed with structure similar to the structure of the plate 30. The three putty plates 30, 108 and 200 are composed of a nylon material.
