Electrochemical and metallurgical industry . ecti-linearly extended through two bearings in aframe, and held in position by collars. This ex-tension is free to revolve in the bearings, andit is the axis of rotation of the tongs.

Therefore, if by means of a crank,fastened to the end of one of the extendedprongs, one of the forks is turned and the scori-fiers tilted to the desired angle, the others per-form the same rotation. The center of gravityof the scorifiers lies to one side of the rotationpoint, and they would, therefore, on beinglifted, tilt in that direction; this, however, beingprevented by the cross-bar resting against a postat that end of the frame toward which the inclination tends. The scoriners are clutched by the upper prong of the tongs,which is fastened to a spring on a post of the fork below, and?which is free to move in a vertical plane, the pivotal point.
