Patent number: 6616371Abstract: A cover for in-ground meter enclosures used in traffic loading conditions employs a relatively thin plate member formed of a ductile iron alloy and is dimensioned to extend laterally across a top opening of an in-ground meter enclosure. A plurality of relatively thick rib members of the ductile iron alloy are formed with and extend generally normal from the bottom side of the plate member. The plate member and the rib members together have sufficient strength and ductility to withstand total loads on the order of at least about 20,000 pounds on the top side of the plate member.Type: GrantFiled: March 13, 2002Date of Patent: September 9, 2003Assignee: Okie Doakie Sales, Inc.Inventor: Richard Pate

Patent number: 6616370Abstract: Method and assembly for inspecting the contents of a connection box or a utility system such as a sewer, telephone electrical, gas etc. via an inspection plug. The inspection plug provides an inspection port and is insertable into a hole in a panel and is attachable to the panel by fixing elements such as a nut assembly, a locking mechanism, prongs, etc. The inspection plug may include a body, a peripheral shoulder, and a resiliently braced cap pivotally mounted in the body to close the inspection port. The peripheral shoulder supports the plug in place in the panel. The cap normally closes the inspection port, but is yieldably openable to allow an inspection probe or other device to gain access to the internal atmosphere for testing within the utility system or electrical connection box. The interior space of the body may contain a gel material, and the cap can be substituted with a resilient closure member having self-sealing openings therein for receiving an inspection probe.Type: GrantFiled: January 17, 2001Date of Patent: September 9, 2003Inventor: John A.

Patent number: 6588810Abstract: A closing device with selective locking for closing a frame includes a roughly flat lid selectively applied to the frame, a lock connected with the lid, and a key which has a socket and an arm, one end of the arm carrying the socket. The lid has an opening for access to the lock by the key, the lock has a latch which cooperates with a catch of the frame, and the key selectively assumes, with respect to an opening, a locking position which the key can leave freely and in which the latch is trapped by the catch, and an unlocking position in which the key is trapped in the opening and in which the latch is disengaged from the catch. The arm and the socket of the key are roughly perpendicular to one another, and the arm is roughly perpendicular to the lid when the key is in the unlocking position.Type: GrantFiled: March 12, 2001Date of Patent: July 8, 2003Assignee: NorincoInventor: Jean-Jacques Monneret

Publication number: 20030121216Abstract: A shroud for use in combination with a septic tank having an access opening and an access cover. The shroud surrounds the access opening and facilitates removal of the access cover covering the access opening and providing access to the septic tank. The shroud comprises a contiguous sidewall opened at first and second opposed ends thereof with an access passageway extending therebetween. A first open end of the shroud has an annular surface for abutting engagement with a top surface of a septic tank. A retaining member retains the annular surface, at the first end of the shroud, in abutting engagement with the top surface of the septic tank. A removable shroud cover seals the second open end of the shroud and the shroud cover, when removed from the second end of the shroud, facilitates access an interior cavity of the septic tank.Type: ApplicationFiled: December 28, 2001Publication date: July 3, 2003Inventor: Melvin Travis Nale
