Abstract
A grate for industrial furnaces wherein pairs of stationary grate bars flank movable grate bars. The grate bars of each pair are connected to each other by an elongated coupling device which extends through one or more elongated slots of the movable grate bar between them. The coupling device has two bolts whose heads are pivotably anchored in the downwardly extending ribs of the stationary bars and an internally threaded sleeve which is located between the slots in two downwardly extending ribs of the movable grate bar and meshes with the shanks of the two bolts. The shanks have oppositely inclined threads and the sleeve is held in the selected position by a lock nut. The ribs at the undersides of the two stationary bars have vertically extending slots which are open at the lower ends to allow for introduction of the shanks of the respective bolts, and the upper ends of the slots are enlarged to take portions of the heads of the bolts and to thus prevent rotation of bolts relative to the respective grate bars.
