Abstract: In a hydrant assembly, the combination comprising an outer tubular member having a first flow port.; an inner tubular member having a closure thereon to close the port in relatively axially advanced position of the closure, and to open the port in relatively axially retracted position of the closure that allows fluid flow through the port to an outlet, control means to control relative movement of the inner and outer members. A second port may be located sidewardly of the outer tubular member to pass fluid in relatively retracted position of the closure to relieve fluid pressure in space formed between the inner and outer members, the inner member being elongated and extending lengthwise in the outer tubular member. The outer tubular member may consist of plastic material. Travel of the closure acts to allow expansion of fluid as it freezes, to relieve pressure build-up within the assembly.

Abstract: A method of draining a standpipe includes moving a valve control device toward a closed position sufficient to uncover at least one drain hole before the valve control device achieves a fully closed position, the at least one drain hole being disposed in a slot of a saturation ring and draining a contents of the standpipe through a drain route to an external portion of the standpipe, the drain route is defined by the drain hole in the valve seat ring, drain ports in the drain ring, outlet notches and a drain channel in the saturation ring. The drain hole is radially offset from each of the drain ports in the drain ring and each of the drain ports are radially offset from each of the outlet notches in the saturation ring. A valve control device is also disclosed.

Abstract: A valve assembly for a faucet includes a spout, a valve stem, a first valve, and a second valve. The first valve is rotatably coupled to the valve stem upstream from the spout and is selectively positionable to control a flow of fluid from a fluid source to the spout. The second valve is rotatably coupled to the valve stem for selectively draining fluid from the valve assembly. Further, the second valve is coupled to the first valve such that when the first and second valves are positioned in a first operational position, fluid flows from the source through the spout, and such that when the first and second valves are positioned in a second operational position, fluid is substantially prevented from flowing from the source through the spout and residual fluid within the faucet is gravity drained from the faucet.

Abstract: A yard hydrant includes a head section with a nozzle, a standpipe and valve housing in traditional hydrant relationship that is constructed and assembled into an integral unit which cannot be disassembled. An operating rod with valve means reciprocates in the standpipe and a valve housing in a well known manner. The rod extends through an enlarged opening formed in the head section for which there is provided a novel two piece gland unit with one piece being a packing gland nut for seal engagement with the operating rod in a well known manner and the other piece being a concentrically larger nut that is removably mounted in said opening in a watertight relationship thereto and in pressing engagement with the packing gland nut. Removal of the gland unit permits the operating rod and any attached components to be quickly and easily withdrawn from the integral unit through the opening in the head section for servicing or repairs.

Abstract: An anti-siphon and freezeless water hydrant comprises a unitary cast metal housing which incorporates a hose bib, and a drain opening cylinder equipped with drain orifices and a drain valve seat. The housing is shaped and labeled to assure installation so that the hose bib is higher than the drain opening cylinder. A unitary valve stem includes an integral drain valve element which selectively engages or disengages the inside of the drain opening cylinder to shut off or open the drain orifices and a water valve element which selectively engages or disengages a water valve seat within the hydrant to act as a water valve. When the water valve is fully closed, the drain valve element opens the drain opening cylinder to permit water trapped within the hydrant to drain through the the drain orifices. The hose bib is equipped with a vacuum valve to prevent back-siphoning of fluids from a hose attached to the hydrant.

Abstract: A water hydrant defines an elongated flow passage having a water inlet and an air inlet, and a laterally extending water outlet spout disposed therebetween to define an outlet. An elongated rotatable stem is reciprocated within the flow passage, and terminates in an exterior handle. A water inlet valve is connected to the stem for control of flow from the water inlet into the passage and an air valve is connected to the stem to control inflow of air and preclude outflow of water through the air inlet. A first check valve in the spout precludes backflow of water into the passage, movement of the air valve opening the first check valve during operation of the handle. A second check valve in the spout downstream of the first check valve precludes backflow of water into the spout. A drain orifice, open to the atmosphere, extends through the spout between the check valves.

Abstract: A flush hydrant for purging waterline systems of subdivisions, rural districts, etc. The flush hydrant is used in lieu of a typical fire hydrant for purging such waterlines of foreign matter which may have infiltrated the waterline system as a result of line breakage. The flush hydrant includes a barrel generally having an upper portion extending above ground and a lower portion below ground. The hydrant includes a ball valve assembly mounted in the lower portion of the barrel and an operating rod extending above ground from the valve assembly. The rod operates a closure member in the ball valve between open and closed positions. The closure member is provided with a primary passageway to direct water into the barrel and out of a nozzle secured thereto, and, with secondary passageways to drain water from the barrel to the outside of the assembly after the valve has been closed by the closure member.

Abstract: The present invention is for a freezeless ground hydrant having a nozzle above ground and having a main valve adapted to be connected to an underground source of water pressure at a point located below the frost line in the soil. Also underground is a drain water storage system including a storage cylinder. When the hydrant is turned off, the residual water in the nozzle drains into the cylinder and is retained there until the hydrant is turned on again. When the hydrant is turned on, a mechanical linkage connected to the hydrant handle causes the cylinder to expel the drain water therein through a drain line which extends upwardly above the ground.

Abstract: The ground hydrant of the present invention includes an outlet nozzle above ground and a drain water collection cylinder located below the frost line of the ground. When the hydrant is shut off, the residual water in the nozzle drains into the ground water cylinder and is stored there below the frost line. The next time that the hydrant is turned on, the piston within the cylinder forces the stored water in the cylinder outwardly through a drain line where it is expelled above the ground. The force for moving the piston within the cylinder is provided by water pressure which is diverted from the water source to move the piston and force the stored drain water out of the cylinder and onto the ground. When the hydrant is turned off a second time, the residual water within the hydrant drains again into the cylinder where it is stored until the next time the hydrant is turned on.
