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 Removal of the gland unit permits the operating rod and any attached components to be quickly and easily withdrawn from the integral unit through the opening in the head section for servicing or repairs.

Dependent claims

A yard hydrant, comprising:

a valve housing with valve means located below ground level for connection to a source of water supply under pressure,
a head section with an integral discharge nozzle positioned above ground level,
a thin wall standpipe free of any threads and irremovably secured at one end to said valve housing and irremovably secured at the other end of said head section to provide an integral unit that cannot be disassembled,
said head section provided with an opening in axial alignment with said standpipe and said valve housing,
an operating rod disposed in said standpipe for reciprocation therein so that one end thereof extends upwardly through said opening and the other end thereof extends into said valve housing and has valve means adapted for valve association with said housing for opening and closing water flow therethrough,
said opening being concentrically wider than said operating rod and any valve means associated therewith,
operating means to reciprocate said operating rod,
removable packing means in said opening to stabilize said operating rod and to serve as a sealing closure for said opening, and
upon removal of said packing means from said opening said operating rod and said valve means being attached to said packing means for direct removal through said opening solely by reciprocation of said operating rod for servicing means without disassembling said valve housing, said standpipe and said head section.

6 more elements

In a yard hydrant, the combination of:

an integral hydrant structure defining a head section having a discharge nozzle located above ground level, a valve housing spaced below said head section and located below ground level, and a thin wall standpipe free of any threads permanently secured to and between said head section and said valve housing,
said head section provided with an opening in axial alignment with said standpipe and said valve housing,
an operating rod disposed in said standpipe for reciprocation therein so that one end thereof extends upwardly through said opening and the other end thereof extends into said valve housing with said operating rod having valve means adapted for valve association with said housing to open and close water flow therethrough,
operating means to reciprocate said operating rod, and
removable packing means in said opening to stabilize said operating rod and to serve as a sealing closure for said opening, and upon removal of said packing means from said opening said operating rod and said valve means being attached to said packing means for direct removal through said opening solely by reciprocation of said operating rod for servicing means without disassembling said valve housing, said standpipe and said head section.
