  • Patent number: 7588049
    Abstract: The claimed universal polymeric molded fire hydrant is lightweight, weather resistant and will meet the UL, FM, NFPA and AWWA standards established for conventional metallic hydrants. Polymeric fire hydrants will also exceed standard performance expectations by eliminating rusting, binding, cracking and the associated need for periodic painting and lubrication. This polymeric fire hydrant costs less to produce than traditional metallic models providing significant costs savings to commercial and residential developers as well as municipalities. The inherent light weight nature of the units will reduce manpower and heavy equipment required to install it. This hydrant can be manufactured to resemble all existing traditional hydrant designs and performance specifications and will allow for future design modifications as future performance specifications and designs evolve.

  • Patent number: 6901950
    Abstract: Fire hydrant locking devices prevent fire hydrants from being turned on without a key. A fire hydrant has a keyhole in its sidewall. A security bolt is threadedly inserted into the keyhole with one end frictionally engaging with the valve stem in the interior of the fire hydrant in one embodiment. In an alternative embodiment, the security bolt pushes a locking pin through a locking pin hole in the valve stem. The security bolt has key projections that are accessed through the keyhole by a key wrench. The key wrench has key slots that mate with the key projections. The key wrench has a handle for applying torque to the security bolt. The fire hydrant has hose connection ports connected to its sidewall that are removably covered by covers.

  • Patent number: 6684900
    Abstract: A device and method for installing yard hydrants which renders the yard hydrant easily installed and replaced. The device includes a buried adapter, a sleeve, and a cap. The buried adapter has an inlet for attachment to a buried water system pipe, an outlet for attachment to a valve body of a yard hydrant, a peripheral wall for attachment to a vertical sleeve, and a drain hole. The sleeve is preferably a pipe sized to receive the valve body of a yard hydrant. The cap illustratively includes an internally threaded collar screwed onto the top of the sleeve and two cover pieces locked to the collar against rotation, each cover piece having an upturned flange with semi-cylindrical recesses which clamp the standpipe of the yard hydrant between them. The device is attached to an underground water pipe, the yard hydrant is then inserted into the sleeve and removably screwed onto the adapter, and the cap is applied to lock the yard hydrant in place.

  • Patent number: 5303961
    Abstract: Proper access for enabling fire hoses to be readily coupled to the hose connections of a fire hydrant is provided without needlessly sacrificing valuable adjacent parking space for motor vehicles by utilizing upwardly oriented fire hydrant hose connections and/or by utilizing open-walled, cage-like protective enclosure components to maintain good and sufficient hydrant clearance and hose connection access space in regions that extend about the hydrant's hose connections. In one preferred form, rounded elbow pipe segments are threaded onto the hose connections of an existing fire hydrant and are rigidly secured in place thereon to provide upwardly oriented fire hydrant hose connections, and/or protective enclosure components are attached to the existing fire hydrant to provide an open-walled cage-like structure that maintains proper obstruction-free access space in regions that extend about the hydrant's hose connections so that fire hoses easily can be coupled to the hydrant.

  • Patent number: 5121772
    Abstract: A three-way wet barrel fire hydrant includes an enlarged intermediate barrel section, which effectively reduces pressure loss in the fire hydrant. The hydrant barrel is formed by an improved sand molding process which requires the mold parting line of the barrel to be selected to coincide with the centerline of the upper nozzle opening. In this manner, a pattern which forms the sand mold may be removed cleanly from the molding sand, thereby eliminating the need of multiple side cores during the casting process.
