Abstract: Anti-scald apparatus for inclusion on a water mixing valve of the type commonly used in showers. The apparatus permits normal manual operation of the valve from an off position, through intermediate positions that allow mixtures of various proportions of hot and cold water to pass through the valve and toward the maximum temperature hot water position. However, the valve cannot be adjusted to reach this maximum temperature position without the performance of a positive, manual procedure by the valve operator, thereby reducing the possibility of accidental or inadvertent scalding. Stop means carried by the valve operating handle and easily accessible to the valve operator cooperate with a fixed stop on the valve to preclude valve adjustment beyond a predetermined high temperature setting until the stop means manually are disengaged.

Abstract: A closure head of a plumbing valve engages a protruding bead formed around one opening of a hollow highly flexible sealing member. Supply fluid is conducted to the interior of the sealing member through another opening. The hollow sealing member provides a flexible lip surrounding the bead, the lip responding to pressure of the supply to urge the bead firmly into engagement with the closure head. The lip deflects upon engagement with the closure head and its inner side is free of restraints that would prevent deflection. Limits are placed upon movement of the head while no effective limits are placed upon deflection of the lip. A lip around the supply port to the sealing member also effects a static seal. The sealing member is snap fitted into the bottom of a removable cage.

The valve positioning handle includes an extended fitting centrally aligned with the isolation member and has a number of working surfaces thereon for the receipt of different torque applying tools. A connecting section between the extended fitting and the isolation member is designed to fail prior to the generation of any excessive forces which might destroy the valve or pipe by a tool being utilized to rotate the fitting.

Abstract: An improved plug valve has means for operating a stem and plug assembly therein, including a sleeve secured within an opening in a valve cover plate, and a tubular gland which is threadably engaged in the sleeve and which coacts with upper and lower stop means incorporated into the stem to raise and lower the plug. Annular sealing rings are employed between the valve stem and the gland and between the gland and the sleeve to prevent leakage, especially when the plug is in a raised position. The upper end of the gland is shaped to receive means for turning the gland to thereby raise or lower the valve stem and plug assembly. A lock nut is rotatable about the gland and selectively against the upper end of the sleeve, whereby the gland may be tightly secured in the sleeve to thereby hold the plug in a sealing position within the valve bore.

Abstract: A valve positioning handle for a plastic valve includes a fluid isolation member rotatably disposed in a valve body and rotatable therewithin by means of different torque applying tools having legs selectively engageable with discretely oriented working surfaces.

Abstract: The invention relates to a thermostatic control unit for radiator valves, this unit being of the type which has an adjustable bellows. The bellows is adjusted only during initial calibration of the thermostatic control unit or when the temperature setting of the unit is changed. The control unit includes a screw and nut arrangement in which the nut is attached to the free or moving end of the adjustment bellows. About three turns between the screw and the nut have been found suitable to provide a sufficient movement of the nut to allow an adequate adjustment of the bellows. A problem with prior units of this type is that if the screw is turned inwardly more than three turns the thread may bottom and thereby cause an excessive and damaging torque to be transmitted to the bellows. Alternately, if the screw is turned outwardly to disengage from the nut, the nut becomes cocked in the enclosed casing and it becomes impossible for the screw to re-enter the nut.

Abstract: This invention relates to a ball type shut off valve. The valve includes a body having a flow passage therethrough defining a seat. A ball is loosely held within the flow passageway by the two ends of a shaped, flat strip spring which is held in a longitudinal diametral slot, in a cylindrical shaft positioned in and sealed to the body, with the axis of the shaft at right angles to the longitudinal axis of the body, and to the flow path of the fluid. Rotation of the shaft causes the strip spring to rotate and to control the position of the ball relative to the seat. Rotation in one direction causes a first end of the spring to move the ball away from the seat. Rotation of the shaft and the spring in the other direction causes the second end of the spring to move onto the sea and to hold the ball against the seat by the compliance of the second end of the spring.
