Abstract: A stopper drain guide stem is provided for centering and positioning a stopper in a drain guide hole. The unitary guide stem has a spindle portion extending axially downwardly therefrom for attachment to a drain stopper. The downwardly extending flexible stem portion of the guide element has a radiused nose portion for supporting the drain stopper in its raised, draining position, and for centering the stem and guiding it into a central aperture of the drain body assembly. The intermediate length of the stem portion is bifurcated, having a pair of spaced apart, substantially parallel flexible leg portions with a flexible spacer member extending therebetween intermediate their length, to promote flexibility of the stem, so as to enable its use in a wider range of sizes of guide hole, and to enhance lateral stabilizing frictional engagement of the stem with the inner peripheral surface of the drain guide hole.

Abstract: It has been found that by mounting a suction cover onto the periphery only of a suction interconnection member placed between the suction cover and the recirculating piping, and by carefully placing the hole pattern and size of the individual holes thereon, that a substantial increase in the allowable flow rate gpm for a given safe suction of below five pounds will be produced, as required by the IAPMO standards. Furthermore, it has been found that the suction cover should provide as clear and unobstructed a path to flow, to the internal bore of the suction interconnect member, as possible, and, to this end, the suction cover itself is completely free of any internal flow obstructions, as is the flow path to the internal bore of the suction interconnect.

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.
