Custom, and in a measure perhaps prejudice, has estab-lished a standard form of bell and spigot joint for castiron pipe, departure from which is not easily joint requires such an amount of lead for calkingthat anv successful means for reducing its volume is of. miisiii Tightening Wedge Filler for Cast Iron Ploe Joints. concern to the water works manager. In the accompany-ing illustrations is shown a device for reducing the leadrequired for pipe joints, and incidentally for increasingthe strength of such joints. The section shows a stand-ard joint made with the new filler. The filling is startedwith jute in the usual manner. The wedge ring is thenbent around the spigot and pressed into the joint. Asecond calking with a small amount of jute follows toforce the wedge ring out from the spigot and tight againstthe inside of the bell. The final step is pouring the leadin the usual manner. The feature of this joint is the ringof wedges, a section of which is shown by the wedges are of cast iron, cast like beads into a steelwire. The wedges are cast in strings of different lengthsto fit joints of different diameters. The advantages of theconstruction described are a saving of nearly 50 per centin the amount of
