ABSTRACT:
A fire hydrant comprising a barrel member having an open upper end with an apertured type closure member detachably secured thereto, the apertured top closure member including a generally flat plate portion and a downwardly extending annular portion. The top closure member is secured to the barrel member by bolt means arcuately spaced therearound and the closure member together with the operating nut define a lubricant reservoir for lubricating the hydrant valve stem and cooperating operating nut. A hold-down nut received in the apertured top closure member holds the operating nut relative to the closure member for rotation and an inverted dish-shaped weather cap is threadedly received on the hold-down nut to protect the bolt means holding the closure member on the barrel as well as to protect the access means for the lubricant reservoir. The arrangement of the upper portion of the fire hydrant is such that components thereof may be used interchangeably as modules with different shaped barrel assemblies and yet the overall hydrant configuration will have a flat modern appearance due to the dish-shaped weather cap.
