Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
An endless traveling grate for transporting material through a heat exchange zone, having a substantially horizontal upper run, a descenDing section, a lower run and a rising section, wherein the improvement comprises a series of support plates each comprising a hinge, each plate having at one end an arcuate portion the axis of which is the axis of the hinge, having a portion at its other end in sliding contact with such arcuate portion of the succeeding support plate, and having, rigid therewith, at least one arm which extends beyond said other end and is pivotally connected to the hinge of such succeeding support plate, the inner sides of the support plates forming open, pocket-like recesses between adjacent such arcuate portions, a receiving container which has a wall that terminates close to the inside of the rising section of the grate, for receiving material that has fallen from the recesses of the upper run of the grate and a transversely extending conveyor positioned below said container, for receiving and removing material from the receiving container.
