20150330062 | REMOVABLE FIRE HYDRANT NOZZLE WITH IMPROVED LOCKING STRUCTURE - A removable hydrant nozzle with a locking arrangement for securing the nozzle in a nozzle opening. The locking arrangement includes an axially movable slide configured to selectively engage a portion of the hydrant adjacent the nozzle opening, such as a lug mouth in a quarter-turn fitting. The slide is mounted to a slide housing and is spring loaded. In use, the slide automatically retracts as the nozzle is inserted into the nozzle opening and automatically extends into locking engagement with the mouth when the nozzle becomes fully seated. Once engaged, the slide prevents removal of the nozzle until manually disengaged. The slide may be movably mounted on a pair of shoulder bolts. The slide may include a paddle that extends outwardly where it is accessible to the operator. The nozzle may include a handle and a seal fitted onto the inner axial end of the nozzle. | 11-19-2015 |
20140250794 | FLOATING MANHOLE FRAME ASSEMBLY - A manhole frame assembly according to one embodiment of the present invention generally includes an upper frame and a lower frame, and is adapted to support a manhole cover. The upper frame may be allowed to float with respect to the lower frame, enabling the upper frame to move during installation, or as the surrounding structure moves, or both. By being capable of movement, the upper frame may potentially prevent uneven transitions between the manhole frame assembly and the surface of the surrounding structure. | 09-11-2014 |
