Abstract: A watertight chimney assembly prevents infiltration of water in the region between a manhole cover support frame and a concrete manhole assembly. The watertight chimney, in one embodiment, is comprised of a pair of tubular telescoping sleeves each provided with a flange for mounting respectively to and between the top lip of a manhole assembly and the bottom surface of a flange on the cover support frame supported a desired distance above the top of the manhole assembly to maintain the cover frame at proper grade. An O-ring seated within an annular groove provided in one of the tubular sleeves provides a sliding watertight seal therebetween. The sleeve flanges are arranged and compressed between the cover support frame and manhole assembly and contribute to the watertight seal. One of the sleeves is reversible to increase the telescoping range between a minimum and a maximum extension. In an alternative embodiment, the internal surface of the manhole opening constitutes one of the telescoping members.

Abstract: A gasket for providing a watertight seal between an opening and a cast member and a conduit extending into said cast member, the gasket being an annular member having an outer circumferential portion of inverted T-shaped cross-section for embedment into the opening of the cast member and a flexible web-like portion extending inwardly from said anchoring portion and terminating in an annular enlarged beaded portion. The length of the web is greater than the distance between the outer diameter of the beaded portion and the inner diameter of the anchoring portion to form a curved configuration. The beaded portion has an inner diameter adapted to cause the beaded portion to undergo at least slight expansion when a conduit is pushed through the central opening defined by the beaded portion whereby the over-center position of the beaded portion may be reversed simply by movement of the pipe.

Abstract: A bidirectional gasket providing a water-tight seal between an opening in a manhole assembly and a pipe extending into said opening, comprises a T-shaped anchoring portion for embedment in a manhole opening A substantially A-shaped pipe engagement portion is joined to the anchoring portion by a slender connecting web facilitating bending of the gasket. The A-shaped portion has "legs" and recesses which form water pockets preventing water from entering. The durometer of the gasket material enhances the water-tight seal of the legs with increasing water pressure. The pipe engaging portion accommodates a greater outside pipe diameter compared with conventional connectors due to reduced volume, by providing voids within the connector together and a lower durometer of gasket material. The gasket has enhanced ability to accommodate diameter deflection or ovation in rigid and flexible pipe materials.

Abstract: Cast members are provided with a liner assembly to protect the cast material from corrosion. The liner assembly is formed of a plurality of curved liner sections having integral joining flanges. A resilient compressible gasket is arranged between opposing flanges and is provided with at least one flange receiving slot for receiving the flange of one of said liner sections to facilitate assembly thereof. Fastening means join the opposing flanges to compress the gasket and thereby provide a liquid-tight joint. Integral flanges are provided at the upper and lower ends of the liner sections to receive a sealant which is squeezed out of the seams formed by the mating sections when joined to protect the cast assembly from corrosion. The liner sections are formed of a material which is inert to the corrosive influences.
