Abstract

1,032,839. Manhole extensions. T. A. PELSUE. March 29, 1965 [March 30, 1964], No. 13155/65. Heading F2P. An extension 10, for use with manholes which are bordered by a ring 12 and have a lid-supporting shoulder 16 recessed into their top, comprises an upstanding tubular member 24 having at each end a pair 32, 34 and 42, 44 of spacedapart parallel flanges which are connected by a cylindrical wall section, 36 or 46, and which house therebetween a resilient inflatable ring 26; the one wall section 46 comprising a part of the wall member 24 and the other 36 being of lesser diameter, and the radial flange 32 comprising the connection between the wall member 24 and the wall section 36 which is of reduced diameter. The extension is seated on the shoulder 16 and the ring 26 is inflated to form a fluid-tight joint in the shoulder recess 20 of the ring 12. The outer diameter of the inflatable ring between the small-diameter flanges is substantially the same as the internal diameter of the wall member 24, so that the extensions may be stacked one upon another. Apertures 38 and 48 are provided through the wall sections 36 and 46 for the inflation valves 40 of the rings.
