Stoker and grate therefore

A stoker comprising a support frame, a first plurality of longitudinally spaced mounting means disposed on said support frame, a first plurality of longitudinally spaced sets of grates mounted on said first set of mounting means, a second plurality of longitudinally spaced mounting means disposed on said support frame, a second plurality of longitudinally spaced sets of grates mounted on said mounting means, each set of said second plurality of sets of grates being interposed between a set of said first plurality of sets of grates and another of said sets of grates, each of said sets of grates comprising a plurality of transversely spaced grates, each of said grates having an underside surface and an upper surface for supporting a grate of a longitudinally successive sets of grates, each of said grates being pivotally connected to a mounting member for pivotal movement about a transverse axis, each of said mounting means including means for restricting the downward pivotal movements of the grates pivotally mounted thereon and means for reciprocating said second plurality of sets of grates relative to said first plurality of sets of grates.

A grate comprising an elongated body having a forwardly disposed, underside surface and a rearwardly disposed means for connecting said grate to a support member, at least one side of said body having a laterally projecting flange adapted to be positioned with a cooperating, laterally projecting flange of a similar grate in overlapping relation, said flange terminating at a forwardly disposed end thereof in spaced relation to said underside surface, and a projection on the grate disposed to engage a portion of an adjacent grate to prevent separation of the overlapping flanges, said projection is an extending nose projecting below said terminating point of the flange on an adjacent grate thereby preventing any relative vertical movement of the adjacent grates.

A grate comprising an elongated body having a forwardly disposed, underside surface and a rearwardly disposed means for connecting said grate to a support member, at least one side of said body having a laterally projecting flange adapted to be positioned with a cooperating, laterally projecting flange of a similar grate in overlapping relation, the underside of said body having a finned configuration, and a projection on the grate to prevent separation of the overlapping flanges, said projection is an extending nose projecting below said terminating point of the flange on an adjacent grate thereby preventing any relative vertical movement of the adjacent grates.

A grate comprising an elongated body having a forwardly disposed, underside surface and a rearwardly disposed means for connecting said grate to a support member, at least one side of said body having a laterally projecting flange adapted to be positioned with a cooperating, laterally projecting flange of a similar grate in overlapping relation, said flange terminating at a forwardly disposed end thereof in spaced relation to said underside surface, said body including a longitudinal body portion and a forwardly disposed depending body portion, said underside surface disposed on said depending body portion and said flange including a portion projecting laterally of said longitudinal body portion and a portion projecting laterally on said depending body portion.

A grate assembly comprising mounting means, a grate having an elongated body portion and a hub portion projecting rearwardly of said body portion, said hub portion having means for connecting said grate to said mounting means for pivotal movement about a transverse axis, and said mounting means having a portion thereof engagable by said grate to restrict the downward pivotal movement of said grate.
