Patent number: 7225837Abstract: An integrated casing spacer and joint restraint unit is attached to each of a pair of pipe sections adjacent to an end-to-end connection of the pipe sections by means of first and second spacer/retainer ring members. Disposed on the outer periphery of each ring member in a spaced manner are plural risers each having a respective runner disposed on its outer end for engaging an inner surface of an outer casing and maintaining fixed spacing between the inner pipe sections and the outer casing. Plural paired risers, with one riser disposed on each ring member, are aligned with one another along the axis of the connected pipe sections and are each adapted for secure connection to a respective connecting rod for securely coupling the two ring members together and restraining relative movement between the two pipe sections.Type: GrantFiled: September 1, 2006Date of Patent: June 5, 2007Assignee: Cascade Waterworks Manufacturing Co.Inventor: William L. Kane

Patent number: 7104572Abstract: Plural spaced projections attached to the outer surface of a branch pipe of a tapping sleeve positioned on a main water line are disposed in contact with a rubber gasket also positioned on and disposed about the branch pipe. A two-piece split gland is also positioned about the branch pipe and engages a first surface of each of the projections. The split gland is adapted for coupling to the flange of a mechanical joint tapping valve by plural nut and bolt combinations for urging the gasket into intimate contact with a second opposed surface of each of the projections and the tapping sleeve's mechanical joint in forming a seal with the branch pipe. The split gland coupling allows for vertically orienting the tapping sleeve even when the main water line is not level, or horizontal, to facilitate tapping valve access via an extension pipe when the tapping sleeve is buried.Type: GrantFiled: October 27, 2004Date of Patent: September 12, 2006Assignee: Cascade Waterworks Manufacturing Co., Inc.Inventor: William L. Kane

Patent number: 6588767Abstract: A mat gasket for use with a tapping saddle is disposed about an aperture in a main fluid conduit and is further disposed between and in sealed contact with the main fluid conduit and an outer sleeve member. The mat gasket includes an aperture aligned with the aperture in the main fluid conduit and outer and inner portions in sealed contact with the outer sleeve member and the main fluid conduit, respectively. The mat gasket's inner portion is provided with a waffled surface and includes spaced ribs concentrically disposed about and in closely spaced relation to the aperture in the gasket and a pair of opposed, tapered edges. The mat gasket's outer portion is provided with a pair of concentric O-rings disposed about the gasket's aperture for engaging the outer sleeve member in a sealed manner.Type: GrantFiled: July 12, 2001Date of Patent: July 8, 2003Assignee: Cascade Waterworks Manufacturing Co.Inventor: William L. Kane

Patent number: 6173967Abstract: A branch gasket for a tapping sleeve is disposed about the side branch aperture in a main fluid conduit and between and in sealed contact with the main fluid conduit and an outer sleeve connected to the side branch. The branch gasket is comprised of a flexible, compressible, resilient material and includes a hydraulic lip, a stainless steel insert ring, a first pair of inner O-ring seals in intimate contact with the main fluid conduit, and a second pair of outer O-ring seals in intimate contact with the outer sleeve. A mat gasket for use with a tapping saddle is disposed about an aperture in a main fluid conduit and is further disposed between and in sealed contact with the main fluid conduit and an outer sleeve member. The mat gasket includes an aperture aligned with the aperture in the main fluid conduit and outer and inner portions in sealed contact with the outer sleeve member and the main fluid conduit, respectively.Type: GrantFiled: September 8, 1998Date of Patent: January 16, 2001Assignee: Cascade Waterworks Manufacturing Co., Inc.Inventors: Samuel W. Eskew, William L. Kane

Patent number: 6095197Abstract: A pipe coupling stiffener is adapted for insertion in each open end of first and second pipes being connected in a sealed manner in a water or sewer line for reinforcing the pipe connection without affecting flow characteristics of a medium carried by the connected pipes. The pipe coupling stiffener includes a generally cylindrical member open at both ends and having a slot extending the length thereof, where the slot is defined by first and second spaced inner edges with the first edge extending transversely relative to opposed ends of the cylindrical member, while the second edge is oriented at a non-transverse angle to form a single-tapered slot. The pipe coupling stiffener further includes a single-tapered wedge adapted for tight-fitting insertion in the cylindrical member's lengthwise slot. The wedge includes curvilinear outer and inner plates having the same curvature as the cylindrical member and an intermediate plate disposed between and attached to the outer and inner plates.Type: GrantFiled: October 11, 1999Date of Patent: August 1, 2000Assignee: Cascade Waterworks Manufacturing Co., Inc.Inventor: William L. Kane

Patent number: 5441082Abstract: A casing spacer includes first and second elongated, steel shell members comprised of stainless steel or high strength steel with corrosion inhibiting coatings, with each shell member having a semi-circular cross section for engaging and enclosing a carrier pipe within an outer casing. Attached to the outer surface of each of the first and second shell members are one or more adjustable risers for engaging the inner surface of the casing in maintaining the pipe, or pipes, in fixed position within the casing. Each riser includes a runner on its distal end to facilitate positioning of the spacer within the casing. The casing spacer's first and second shell members are securely coupled together by way of flange and nut and bolt combinations along one edge and a hook and eye arrangement along a second, opposed edge.Type: GrantFiled: August 30, 1994Date of Patent: August 15, 1995Assignee: Cascade Waterworks Manufacturing Co.Inventors: Sam Eskew, William L. Kane

Patent number: 5288108Abstract: A bell joint repair clamp includes first and second semi-cylindrical sleeve members adapted for secure coupling by lug members drawn together by bolts for positioning about a leaking bell joint. Disposed intermediate the bell joint and coupled sleeve members is a sealing gasket preferably formed of a pair of gasket members each having a trapezoidal cross section and comprised of a deformable, compressible material to allow the gasket members to assume the shape of and engage the spigot and bell-shaped ends of the connected pipe sections in a tight-fitting manner. Opposed ends of the coupled sleeve members are each provided with a retaining plate and pipe clamping arrangement for confining the gasket in a sealed manner between the sleeve members and circumferentially about the bell joint for sealing a leak therein.Type: GrantFiled: October 5, 1992Date of Patent: February 22, 1994Assignee: Cascade Waterworks Manufacturing Co.Inventors: Sam Eskew, William L. Kane

Patent number: 5040828Abstract: A tapping sleeve for attaching a branch line to a main fluid conduit. The tapping sleeve has upper and lower sleeve members, bolted together around the main fluid conduit. Shell gaskets seal between the sleeve members and the main fluid conduit and a branch gasket seals around a side opening in the upper sleeve member. Metal shell gasket retaining rings secure the shell gaskets in place and a metal branch gasket retainer secures the branch gasket. In the preferred embodiment, the retainer is a retaining ring. In an alternate embodiment, the branch gasket is secured by a shoulder formed by extruding the upper sleeve member.Type: GrantFiled: June 18, 1990Date of Patent: August 20, 1991Assignee: Pipeline Accessory Marketing, Ltd.Inventor: William L.
