ABSTRACT:
An apparatus for plugging holes in an electric smelting furnace or the like is disclosed. The apparatus comprises first and second tubular members, the second being adapted to be secured to the first by means of two assemblies mounted exterior of the tubes each of which may serve as either a release or a pivotal element about which the second tubular member may be rotated to facilitate loading and/or cleaning of either tubular member. A piston is provided which travels substantially the longitudinal extent of the first tubular member to extrude, under pressure, a material suitable for plugging a hole.
