[Class 51 (i)] In a travelling grate of the kind comprising links in staggered relation threaded on transverse rods, the links a, as shown in Figs. 1 and 3, are provided with projections b which extend outwardly beyond the fire bearing surface of the link to a distance not greater than one half of the width of such surface. The projections taper upwardly and form abut. ments for the ends of links in adjacent rows which are contoured to correspond. In the event of a link being fractured the broken parts are prevented from turning about their supporting rods by the projections on adjacent bars.
