Abstract:
The sealing assembly includes a relatively soft rubber, tubular sleeve having an axial length sufficient to span the joint between hollow members, such as the corbel joint between a manhole frame and a manhole casing, and a sealing portion in each of the opposite ends. The outer surface of each sealing portion is compressed radially outwardly in sealing engagement with the interior walls of the manhole frame and the manhole casing by a generally circular hoop which fits into a groove provided in the inside surface of the sleeve. Each hoop has circumferentially movable, end portions and a radially inwardly extending bracket mounted on each end portion at circumferentially spaced locations. These brackets are adjustably pulled toward each other, to increase the circumference of the hoop, by tightening a nut threaded onto the outer end of a bolt connecting the brackets together. The distance between the outer ends of the brackets can be adjusted, to maintain the brackets substantially parallel during tightening, by turning a nut threaded onto the outer end of a threaded member spaced radially inwardly from the tightening bolt and connected between the brackets.
