Abstract: 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.

Abstract: A manhole cover assembly configured to behave as a relief valve in an explosion event, opening so that fluid, such as air or explosive gas, may vent from an underground area. The manhole cover assembly may include a manhole cover and a frame, and may be configured to limit movement of the manhole cover with respect to the frame in response to increased pressure on the manhole cover. In one embodiment, the manhole cover may include legs that are configured to enable a range of movement of a portion of the cover such that the cover can be unseated at an angle with respect to the frame to allow fluids to escape from the underground area.

The manhole cover assembly may include a manhole cover and a frame, and may be configured to limit movement of the manhole cover with respect to the frame in response to increased pressure on the manhole cover. In one embodiment, the manhole cover may include legs having angled surfaces adapted to substantially center or guide the manhole cover in the frame while the manhole cover displaces to release pressure. In another embodiment, one or more legs slidable within the manhole cover to enable configuring the manhole cover between a restraint mode and a removal mode.

Abstract: A skirt supports an access hatch at a predetermined height as the hatch is formed in concrete. The skirt can be permanently embedded in the concrete. The skirt includes a rigid frame defining a central opening, the frame has an inner surface and an outer surface opposite the inner surface. The frame defines a height between the upper edge and the lower edge. The height of the skirt is predetermined such that the combined height of the skirt and the hatch approximate the desired thickness of the concrete slab. The skirt may include an alignment tab extending from the frame at an angle with respect to the frame, with the alignment tab extending above the upper edge of the frame to guide the hatch into alignment with the upper edge of the frame as the hatch is moved into position on the skirt.

Abstract: A manhole lock system includes a frame positioned over an access opening, a cover movable between a closed position in which the cover extends over the access opening, and an open position in which the access opening is exposed; and a lock mechanism for locking the cover in the closed position. The lock mechanism includes a lock member that is movable along a path between a unlocked position and a locked position, wherein in the locked position the lock member prevents the cover from moving to the open position, wherein in the unlocked position the lock member is retracted to enable movement of the cover to the open position.
