Abstract: A decorative vase and toilet cover. The decorative vase and toilet cover is made up of a toilet cover with a raised aperture and a perforated basket being attached underneath the raised aperture. The perforated basket and raised aperture form a decorative vase, which can be easily broken down for removal and cleaning. The perforated basket is made of flexible thermoplastic material that is attached to the ceramic toilet cover by a pair of invertedly positioned ceramic buttons and slots. The holes on the perforated basket are approximately 20 mms. in diameter and are macroscopically designed to hold a set of flowers while allowing water to enter through the exterior of the perforated basket.

Abstract: The apparatus consists of a mechanism for supplying water to the toilet and flushing water into lavatory, a vessel with solid cleaning detergent in a saturated solution, a portioning mechanism and a water supplying mechanism. The portioning mechanism supplies equal portion saturated or strong detergent solution into tank with every flush. The water supplying mechanism adds water into the vessel and keeps high level of the detergent solution in the vessel. Because the vessel consists several solid detergent tablets and it is full of saturated detergent solution, and because the portion of the detergent solution pouring into the toilet tank is a small fraction of the volume of the solution in the vessel, and an equal portion water has been supplied after each, the solution of the detergent is always saturated. Because the portion of the detergent solution dispensed is always equal the concentration of the detergent in the water of tank is always equal until the last tablet is dissolved.

Abstract: An apparatus is provided for selecting either potable water or seawater as flush water for marine sanitary toilets. The apparatus may be designed to be electrically or manually operated. Check valves and vaccum breaker prevent contamination or waste of the potable water supply.

Abstract: A device and method for engaging the fill valve assembly in a water closet and maintaining the fill valve assembly in a closed condition regardless to the level of water in the flush tank of the water closet. The device includes two suspension elements that engage the walls of the flush tank on either side of the float lever portion of the fill valve assembly. A flexible element extends between the two suspension elements, wherein the flexible element passes under the float lever as extends from one suspension element to the other. As the flexible element is pulled taut, the flexible element abuts against the float lever and upwardly biases the float lever. The upward bias that is applied to the float lever causes the fill valve assembly to close. The upward bias also prevents the fill valve assembly from leaving its closed configuration regardless to the level of water in the flush tank.

A second tank lever arm (50) is installed into the tank and lifts the flush valves vertical tube (36) causing a partial flush of the water in the tank. The first tank lever arm is attached to the flush valves float assist arm (38) beneath the second lever arm lifting both the vertical tube and float assist (40) delaying the opening until a complete flush of the water from the tank is achieved. A pressure increasing riser (56) is added between the water closet and the water tank to boost the water pressure and more efficiently flush water from the tank into the water closet.

The valve is a dual component device including a housing structure and a lever component. Both the housing structure and lever component have a trunk section of similar shape, but of different size. The trunk section of the lever component fits snugly within the trunk section of the housing structure. The lever component is able to rotate within the housing structure. The trunk sections in both the housing structure and the lever component include openings which provide a passageway for water to flow therethrough. The openings in the housing structure are spherically shaped and the openings in the lever component are pear-shaped. The housing structure includes a pair of tabs disposed 90.degree. from one another for limiting the rotation of the lever component such that the openings in both the housing structure and lever component are always aligned.

Abstract: A toilet tank cover comprises two decorative figures. Discharge from the vent orifice of a cup type float valve flows up through the primary figure and out an exterior orifice to the secondary figure. The primary figure receives water discharge from the discharge vent of a cup type float valve. The discharge then flows through the primary figure to an emission point. At the emission point, the fluid is directed toward an opening in the second figure. The discharge flows through the secondary figure and drains directly into the waste standpipe of the toilet. The operation of the flush mechanism of the toilet is thereby monitored in an aesthetically pleasing fashion.

Abstract: A primer valve for sewer line drain traps is adapted for use in conjunction with a flushing toilet or like installation including a tank containing water of fluctuating level. The primer valve comprises a pipe penetrating the lower portion of the tank and providing a port at its inner end. A conduit connects the outer end of the pipe to the trap.

Abstract: A level indicator for a portable toilet comprises a visible indicator on the exterior of the toilet's holding tank, a float mechanism on the tank's interior operable to sense the level of liquid material in the tank, and a magnetic coupling between the float mechanism and the indicator for causing the indicator to be operated to a position corresponding to the level of liquid material sensed by the float mechanism. The indicator is in the form of a wheel journaled on a receptacle in the top wall of the holding tank. A magnet mounts on the wheel in radially spaced relation to its axis. The float mechanism comprises an arm which is operated along an arc in response to changes in the level of liquid material in the tank. The arm has a magnet which swings in a corresponding arc and which confronts the wheel magnet so that the wheel is rotated about its axis as the float arm is operated about its own axis.

Abstract: An insert installed inside the toilet tank arranged and constructed to decrease the amount of water held in the tank. While the amount of flushing water used for each flush is appreciably less than it would be without this insert in place, the bulk of that water is still delivered to the toilet bowl under an average head higher than that which is normally obtained without the insert. The toilet flushing action is thus as effective as it would be otherwise, but only with a fraction of the water volume being required. The resulting saving of water is substantial and the tank also fills up at a much faster pace. The insert is supported by the bottom and side walls of the existing toilet tank and does not otherwise interfere with the operation of the toilet tank internal equipment. Because no water is allowed to flow between the insert body and the toilet tank walls, this space being sealed off, this insert also provides safety in case the toilet tank walls are accidentally broken.
