The arms define a space therebetween adapted for receiving a portion of a base of a faucet between the arms. A stop tab is extended from the first edge of the clip member.

Abstract: A unitary handle structure to be secured to the shaft of the valve and cooperate with the stops on the body to delimit and lock the valve element in its open and closed positions. The handle structure includes a socket portion fixed to the stem of the valve element and a handle portion extending from the socket portion and doubling back towards the socket portion and terminating at an end adjacent the socket portion. A detent portion on the end includes a pair of walls sufficiently spaced to receive the stops to lock the valve element in the open and closed positions. The handle portion is flexibly resilient to allow the detent portion to raise and lower with respect to the stops. One of the walls of the detent has a height high enough and the end of the handle portion is separated from the adjacent portion of the handle by a sufficiently short distance to prevent the one wall of the detent portion from raising above the stops.

Abstract: A locking device for a parking brake on a bus having air brakes prevents accidental release of the parking brake when a sensing switch indicates that the bus should not move (e.g., when the driver is absent from the driver's seat, or a passenger-access door is open). The locking device of the invention is affixed to a portion of the bus adjacent a parking brake air valve that has an air valve shaft moving along its axis between a fully extended position, in which the valve is in a brake-applied status, and a frilly retracted position in which the valve is in a brake-released status. The locking device has a locking arm moving between a locked position in which it prohibits the parking brake valve shaft from moving into the fully retracted position and an unlocked position in which it does not affect the motion of the valve shaft. Conventionally, the valve shaft has a knob on the end distal from the valve body, and the locking arm in the locked position, prevents the knob from being pushed in all the way.

Abstract: An improved latch mechanism for a fluid flow control valve. The latch mechanism having a latch body, a spring, a plunger and a thumb release lever for disengagement of the plunger. The latch mechanism is attached to a valve handle which controls the fluid flow rate through the valve. Provided with the latch, the handle and thereby the valve can be locked into either a closed or open position at the limits of the valves' necessary rotation thereby preventing inadvertent opening or closing of the valve. The thumb release lever disengages the plunger with detent notches provided in the valve body allowing safe and efficient single handed operation of the handle and latch mechanism even under adverse environmental conditions when operator dexterity is impaired by gloves.

Abstract: A child resistant valve assembly includes a valve with a movable valve stem to regulate the flow of hot water from a bottled water cooler system. An actuator cap is mounted to the movable valve stem, and a hood assembly covers the actuator cap. The hood assembly can slide in a direction generally perpendicular to the direction of movement of the movable valve stem. A spring, generally connected to the side of the actuator cap, lies between the actuator cap and the inside of the hood assembly. The hood assembly includes downwardly projecting tabs. The spring biases the hood assembly toward a position such that the tabs are located directly above the annular upper surface of the valve. Downward motion of the valve stem is thus prevented. When the hood assembly is first moved laterally to allow the stoppers to pass to a position not directly above the upper surface of the valve, the valve stem can be pushed down allowing hot water to be dispensed.

Abstract: A locking valve for controlling fluid flow within a conduit has a spring-biased detent in fluid communication with a fluid source. A movable valve structure prevents fluid flow through the conduit in a closed position and enables fluid flow through the conduit in an open position. Movement of the valve structure from the closed position to the open position is obstructed by the detent when fluid pressure in the conduit is below a predetermined pressure. An increase in fluid pressure, however, moves the detent against the spring bias, removing the obstruction to movement of the valve structure, and allowing the valve structure to be moved to the open position. Thus, accidental or intentional drainage of the conduit when the fluid pressure source is inactive is avoided.

Abstract: The connecting linkage between a control lever and a control valve that controls the operation or the manipulation of an implement of a construction machine is often complex and difficult to properly adjust. The present invention provides a restraint mechanism for the control lever 10 to maintain its position in a neutral condition with respect to the control valve. A first plate 42 is pivotally mounted to a base plate 22 on the console of the machine and is movable to a first position to engage the control lever 10 and establish a neutral position. A second plate 58 is utilized to selectively secure the position of the first plate with respect to the control lever while the proper connections and adjustments are made to the linkage arrangements connecting the control lever 10 and the control valve to synchronize their respective neutral positions.
