Patent number: 8082945Abstract: A top operating telescoping adjustable valve box and valve stem assembly that incorporates a telescoping valve stem actuating system which, when coupled to a service valve, allows for the operation from ground level without the removal of a plug or lid. The system has a large range of vertical adjustability. The upper and lower sections of the assembly are in frictional connection with each other, which allows no transmittal of force to the lower section when any upward force to the upper section is applied, thus reducing damage to the buried valve and pipeline. The assembly provides a tracing block terminal, located on the top base, to allow for the connection of tracing wire from the valve top to the service pipe for service line location. The assembly also incorporates the placement of a tamper proof cap for the prevention of unauthorized operation of valve stem system.Type: GrantFiled: October 1, 2009Date of Patent: December 27, 2011Assignee: E-Z Innovations, L.L.C.Inventors: Dennis Wayne White, John Leonard Jacobs

Patent number: 6354325Abstract: A valve cover for enclosing an underground area surrounding the actuating mechanism of a flow control valve. The valve cover includes a body having a structure configured to position the valve cover in a desired orientation relative to the flow control valve. This positioning structure may be at least partially elastomeric, and configured to resiliently deform and urge against the flow control valve when the valve cover body is placed over the valve actuating mechanism. This maintains the valve cover body seated in a centered, leveled orientation relative to the valve actuating mechanism. The positioning structure may also be formed as a spacer configured to contact the valve actuating mechanism itself and space the actuating mechanism from the valve cover body. The valve cover body is configured so that, when it is installed, a valve tool may be freely inserted into the enclosed underground area and operatively engaged with the valve actuating mechanism.Type: GrantFiled: January 31, 2001Date of Patent: March 12, 2002Assignee: 3 Dimensional Contracting, Inc.Inventors: Kenneth F.

Patent number: 6036401Abstract: A roadway access device such as manhole cover, a storm drain, or a utility valve box which facilitates road paving and grinding operations. The access device includes a riser assembly having an inverted frustoconical top portion that minimizes frictional engagement between the riser and the paved surface and permits repositioning in an elevated plane with no excavation necessary. There is a tapered upper portion that engages with an internally threaded extension nut with tool-engaging receptors and when the nut extension is rotated, the upper conical portion does not rotate, but displaces vertically. There is a riser member that is externally threaded and fixed in position relative to the rest of the assembly around which the extension nut rotates in order to vertically displace the access device. Additionally, there are separate removable lids constructed of high strength material which can be put in place during paving and grinding operations and easily removed when operations are complete.Type: GrantFiled: April 29, 1998Date of Patent: March 14, 2000Inventors: John Morina, Chester Ryan
