A spoon-like tool used to dip the molten lead from the lead pot and pour it into the joint.
Lead and Oakum Joint
A joint for hub-and-spigot cast-iron pipe that involves pouring molten lead over oakum fiber to form a water-tight seal between the two pieces of pipe, then caulking the joint after the lead has cooled.
