ABSTRACT OF THE DISCLOSURE: Apparatus for collecting and removing smoke and fumes from a melting furnace plant comprising a platform tilt- ably supported by stationary supporting members, the tilting axis being near one edge of the platform, a furnace fixedly mounted to the platform, said furnace having a furnace chamber open at the top and accessible through a charging orifice in the platform, said furnace having a pouring spout connected to the upper part of a side wall of the furnace and located near the tilting axis. A hood is pivotably supported by supporting members mounted to the platform and being angularly moveable towards and away from a portion of the platform surrounding the charging orifice of the platform. The pivot axis of the hood is parallel with the tilting axis of the platform and extends at the same side of the furnace as the tilting axis. A pair of parallel wall members are arranged on the upper surface of said platform and extend at right angles to the tilting axis. The wall members extend from the edge of the platform along the platform and have a vertical extent with respect to the plane of the platform such that in any angular position of said hood, the hood together with the said wall members and with the upper surface of the platform define a cowl facing said charging orifice. A first air duct is mounted to said platform, and, a second air duct is stationary relative to the stationary sup- porting members for the platform. The first air duct has an in- let orifice connected to the cowl and an outlet orifice surround- ing the tilting axis. The outlet orifice is connected to and freely rotatable with respect to an inlet orifice of the second air duct.
