Abstract
A grate for industrial furnaces wherein each row of grate bars includes alternating stationary and reciprocable bars. The stationary bars which flank a reciprocable bar are connected to each other by a bolt which extends transversely of the stationary bars and of the reciprocable bar therebetween and has hook-shaped end portions or screws engaging the inner sides of ribs forming part of the stationary bars and adjacent to the respective side of the reciprocable bar. The median portion of the bolt extends through elongated slots in the ribs which are provided at the underside of the reciprocable bar. The latter moves with respect to the bolt and with respect to the adjacent stationary bars.
Claims28
In a grate for an industrial furnace or the like, the combination of a support;
- a pair of spaced apart first elongated grate bars mounted in said support;
- a second elongated grate bar disposed between and movable relative to said first bars;
- and means for connecting said first bars to each other, including an elongated coupling member extending transversely of said bars and having first and second ends, and a retaining element disposed at each of said ends and extending transversely of said coupling member, said first bars including portions adjacent to said second bar and having first openings through which said coupling member extends and inner sides adjacent to the respective retaining elements, said second bar including at least one section disposed between said portions of said first bars and having a second opening through which said coupling member extends and which is sufficiently large to allow said second bar to move with respect to said first bars and said connecting means.
