  • Patent number: 4791952
    Abstract: A hydrant includes one or more novel and improved features, namely: (1) a nozzle assembly comprising a nozzle and a retainer ring mounted from within the upper standpipe section of the hydrant; (2) an operating assembly defining an excess reservoir volume to receive valve stem lubricating fluid to prevent blocking movement of the valve stem; (3) a coupling assembly including a collar, a retainer ring for engaging one end of the collar against one standpipe section, and a retainer bar inserted through the collar and bent around an adjoining standpipe section; (4) a coupling assembly including a floating seal band carrying two seals, one of which seals against one standpipe section and the other of which seals against an adjoining standpipe section; (5) an otherwise conventional valve body but for a double-D valve body cavity in which a complemental boss of a valve member retainer disk is nested to prevent rotation therebetween, and also including a flat sealing gasket disposed between the valve stem and an ann

  • Patent number: 4154259
    Abstract: A fire hydrant having a unitized bonnet configuration or assembly which includes a bonnet member, operating mechanism, external driving attachment and lubricant reservoir and which may be installed and removed from the hydrant barrel without the loss of lubricant from the lubricant reservoir therein or without the major disassembly of parts. Additionally, the unitized bonnet assembly is provided with a stop nut member which may be adjustably secured to the end of the valve stem to compensate for small variations in barrel lengths and/or valve stem lengths. The stop nut member is carried within the lubricant reservoir of the bonnet member and is at all times sealed from water in the hydrant and, thus, it may be made of a non-corrosive resistant material such as ductile iron or steel which is less expensive than corrosive resistant material such as brass, bronze or stainless steel.
