  • Patent number: 4380834
    Abstract: A pop-up plunger for selectively closing a generally cylindrical waste drain pipe having a seat at one end and a closure actuator remote from the seat, the plunger comprises a head portion including sealing means for engaging the seat for closing the waste drain pipe. The plunger also includes a support portion which extends from the head portion into the waste drain pipe. The support portion engages the closure actuator for axial displacement of the plunger relative to the waste drain pipe for opening and closing the waste drain pipe and includes guide means projecting into close proximity to the waste drain pipe for guiding the axial displacement of the plunger. The guide means provides at least one drain passage past the plunger to afford communication from the seat to a drain through the waste drain pipe.

  • Patent number: 4320540
    Abstract: Disclosed is a discharge drain assembly (for use in a sink) including a drain body and a plug assembly adapted to fit in the drain body which features limited rotational movement between an open and a closed position. The plug includes a stainless steel strainer with an integral hollow knob having opposed sides which are inwardly concave. The knob securely but releasably retains a slotted head portion of a spindle. The spindle has a neck portion for receiving a sealing washer and a lower body portion including three leg portions. The leg portions support the plug in the open position, restrain rotation in a first direction beyond the open position, and cam the plug to the closed position when rotated in a direction opposite said first direction. The structure substantially eliminates a "finding" problem common in prior art arrangements and provides a good seal in the closed position.

  • Patent number: 4296778
    Abstract: An anti-backflow valve for sewer traps or catch basins is adapted to automatically prevent the undesirable backflow of sewer water upwardly through a trap, but provides for the normal downflow of water through the trap into the sewer. Such valve arrangement has a top or floor plate for insertion over the top of a conventional catch basin with a slotted valve housing extending downwardly from the floor plate. A conically-shaped sealing member is slidingly disposed for vertical movement within the housing to seal or unseal the trap. An elongate downwardly-extending guide member is attached to the underside of the conically-shaped sealing member. A bottom plate is detachably mounted to the underside of the valve housing and is provided with apertures therein to permit the flow-through of water. The center of the bottom plate is provided with a guide means for slidingly holding the downwardly-extending guide member to prevent canting or misalignment of the sealing member as it slides vertically in the housing.

  • Patent number: 4276662
    Abstract: An improved plug device for the drain of a basin or a bathtub, which is comprised of a roller mounted on a rod and spring enclosed by two semicircular sleeves, which when assembled together form a cylindrical sleeve. The roller is guided by a guide groove which is carried on the inner wall of the two semicircular sleeves. The roller is connected to a drain plug by a rod and spring urges the device upwardly. The guide groove has rest positions so that by simply depressing the plug sequentially, the plug is automatically set in either the open or closed position.

  • Patent number: 4261378
    Abstract: An accessory adapted to be attached to the drain opening of a sink of a parts washer including an upright tubular housing, having a plurality of drain ports at a lower end thereof. A stopper is selectively movable in said housing from a first position above the drain ports to a second position below the ports by the application of force to a shaft operatively coupled thereto. In the first position of the stopper, drainage of fluid from the sink occurs through the drainage port and the drain outlet. In the second position, fluid is blocked from egress through the drain port and the drain opening of the sink and collects in the sink to a predetermined level whereby a series of overflow drain ports drain excess fluid to maintain a constant level of solvent. The shaft is coupled to a spring urging the stopper to the first position when a force is removed from the shaft.

  • Patent number: 4232407
    Abstract: A basket strainer and stopper assembly for a sink includes a strainer basket, a stopper positioned below the basket strainer for sealing the sink drain opening and an axial stem. The stem has an upper portion which serves as a handle and a lower forked portion which has tines or legs which both support the strainer-stopper assembly in the open drain position and retain it securely in the closed drain position. The legs of the forked portion of the stem are resilient and arcuate and they rest upon a plate extending across the drain opening to support the assembly in the open position. The drain is closed by exerting sufficient downward force on the handle portion of the stem to spring the resilient legs toward each other so they pass through and are retained in a detent opening in the plate. The drain is reopened by pulling upward on the handle with sufficient force to raise the entire assembly and to once again spring the legs toward each other so that they will pass through the detent opening.

  • Patent number: 4185336
    Abstract: A deenergized solenoid operated valve normally closes the drain line of a sink, basin, tub or toilet bowl, the valve thus serving as a stopper. When a pushbutton switch is closed, the solenoid is energized to retract the valve and open the drain, a flow responsive switch maintaining the solenoid energized until all of the water has drained from the sink or bowl. A float responsive switch will also energize the solenoid to retract the valve and open the drain if water accumulates from a leaky faucet. Whenever water is drained, the low pressure or vacuum that results produces an accompanying venting action. The invention may be used with a P or S-type drain connection and/or with a conventional stack vent, but does not require that any of these be employed.

  • Patent number: 4128905
    Abstract: A receptacle for temporary retention of fluid as well as for routing fluid from a basin faucet to a basin drain. One disclosed embodiment includes a body member, a valve, a base member, anchoring means and a spacing plate. The body member is positionable beneath the faucet and has an open bowl portion into which water from the faucet can flow. Joined to the base of the bowl portion is a hollow neck portion in which a valve is positioned. The valve is manually operable to open or close a passageway through the neck and thus the valve controls the retention and release of water from within the bowl portion. The anchoring means includes a stem-like member on which compressible, triangularly-shaped bosses are formed. The bosses effect an interference fit with the inner walls of the drain to secure the receptacle in an upright position. The base which is joined to the neck portion includes a flange which rests atop the spacing plate.

  • Patent number: 4088149
    Abstract: A check valve structure for use in a drain such as a floor or pavement drain can be constructed utilizing an annular elastomeric member positioned between two rigid end plates. These plates are connected so that they can be moved toward one another when they and the member are inserted in a drain or drain housing in order to compress the member to cause the member to expand in outer diameter into contact with the interior of the drain or drain housing in order to mount the structure in an operative position. A valve seat is located on the lower plate and a buoyant valve member is movably supported on the upper plate so as to be capable of being moved with respect to the valve seat. In the event of accumulation of water in the drain or drain housing or in the event of back flow into the drain or drain housing the valve member will move against the seat.
