  • Publication number: 20040117899
    Abstract: A toilet cleaning dispenser system adapted for placement in a toilet tank includes a hanger, a dispenser housing and a cartridge device removably coupled to the dispenser housing. The cartridge device, which includes a cleanser tablet enclosed within a cartridge housing, is inserted into a cavity of the dispenser housing and turned in one direction to lock the device and, alternatively, in an opposite direction to unlock the device. The cartridge housing may be formed to turn as one unit, or be formed as a basket and a rotatable cap that can be turned with respect to the basket. The dispenser housing includes an inlet water trap and an outlet water trap, each comprising a pair of concentric, nested tubes that retain liquid after flushing so as to prevent fumes from exiting the dispenser housing into the toilet tank.

  • Patent number: 6604249
    Abstract: A flush valve is adapted to be mounted in the tank of a toilet and includes a selector assembly and a flush valve. The selector assembly is accessible from outside the toilet and provides for initiation of the flushing operation and an alternative choice between a larger flush water volume and a smaller flush water volume. A support structure provides for both axial and radial movement of the selector assembly relative to the flush valve in order to facilitate mounting and aligning of the flush valve assembly. A slide mechanism provides for variation of at least the smaller flush water volume.

  • Patent number: 5551191
    Abstract: A removable lid for a pool skimmer, the lid including at least one, and preferably two, manually operated latches that prevent inadvertent removal of the lid and thereby eliminate a potentially hazardous condition posed by lids that can be removed by wind action, wave action, or by accidentally tripping on an incorrectly installed lid. Preferably, the lid has diametrically opposed latches, each having a bendable member with a camming surface that bends the latch to fit within a skimmer collar and then allows the latch to snap into a retaining position when the lid is completely installed. Access holes in the lid facilitate manual operation of the latches for removal of the lid for maintenance purposes.
