An improved liquid-filled dashpot mechanism for use with a spring-biased, axially-displaceable valve stem, comprising: a housing having a passageway therein, a stem in the passageway adapted for reciprocation therein, a pair of annular rolling diaphragms disposed in spaced-apart, face-to-face relationship within the passageway in the housing, each diaphragm being respectively secured in fluid sealing relationship to the housing and the stem to collectively form an enclosed container for the dashpot liquid, a piston fixedly mounted on the stem intermediate the rolling diaphragms adapted for operative displacement within the housing and dividing the container into two chambers, a liquid metering passageway in the piston for providing fluid communication between the two chambers, and a check valve secured to the piston to permit the unidirectional flow of liquid therethrough, and when the dashpot liquid is not permitted to flow through the check valve, to direct the flow of dashpot fluid through the liquid metering passageway, thereby effecting dashpot action.

Dashpot mechanism for self-closing plumbing valves

Combination lavatory basin and toilet bowl

A waste drain connection for coupling the waste outlet of a plumbing fixture having a receptacle for a fluid-sealing gasket thereabout to a plumbing drain pipe including a fluid-sealing member having a sleeve portion adapted for intimate fluid-sealing about the plumbing drain pipe and an outwardly-extending flange forming a gasket about one end thereof and a sleeve and gasket compression member for containing the sleeve and for compressively urging the sleeve into greater intimate contact with the plumbing drain pipe to ensure a fluid sealing relationship therebetween and for compressively urging the gasket into intimate contact with the gasket receptacle to effectuate a fluid sealing relationship therebetween.

Waste drain connection

A combination lavatory and toilet assembly including a sanitary enclosure having a rear side with a plurality of apertures therein, an upper side including means defining a lavatory basin with a drain opening therein and communicable with a plumbing drain pipe, a front side defining an access opening closed by a pivotally mounted closure member, a relatively pivotable toilet adapted to be stored in a first position within the enclosure and being pivotable about a generally vertical axis to a second position disposed exteriorly of the enclosure to permit use thereof, toilet support and pivot means fixedly coupled to the rear portion of the toilet for supporting the toilet and for pivotal movement between the first and second positions and including means for coupling the toilet to water supply piping and means for coupling the outlet of the toilet in fluid communication with the plumbing drain, wherein the toilet support and pivot means is supported independently of the enclosure, and linkage means operatively connected to the closure member and the toilet support and pivot means, whereby when the closure member is moved away from its closure position, the toilet is moved from the first position within the enclosure to a second position disposed exteriorly of the enclosure to permit use thereof when the closure member has been displaced no more than substantially 90.degree. from its closure position.

Combination lavatory and toilet assembly

A relievable hanger for towels and the like is disclosed which incorporates a ball having a fixed rod extending therefrom. The ball is movably captured within a socket to form a ball joint. A portion of the ball is bored out to receive therein a spring-loaded element with a rounded, blunted end. Positioning the rod upwardly to serve as a hanger for towels and the like disposes the blunted-end of the spring-loaded element over a detent within the socket. The blunted end is urged by the spring into the detent which relievably locks the rod in its upright position.
