ABSTRACT OF THE DISCLOSURE A grate for use in industrial furnaces has a frame which supports a number of elongated parallel grate bars having a T-shaped or U-shaped cross-sectional outline. One end portion of each bar has a socket which overlies a portion of an elongated rail forming part of or secured to the frame. The other end portions or the regions close to the other end portions of the bars are coupled to each other by a transverse shaft which holds the bars against movement at right angles to their longitudinal extensions and away from the frame. A second coupling system is provided close to the one end portion of each bar to hold the bars against movement in the aforementioned direction. The second coupling system may include lateral projections provided on the bars and extending below or into openings of the neighboring bars. Alternatively, the second coupling system may include locking bolts which are affixed to or movable transversely of alternate bars and extend below or into openings of one or both neighboring bars. A single locking bolt can extend through openings in the lower portions of all bars. Alternate bars and eventually the coupling shaft and/or corresponding portions of the second coupling system are preferably reciprocable lengthwise of the remaining bars to allow for convenient expulsion of particles of foreign matter which happen to penetrate into the clearances between neighboring bars. - 1 -
