A stabilized side plate construction for a grate conveyor or the like in which one side plate of each pair of pivotally connected side plates has loosely keyed thereto a flanged spool which is journalled for pivotal movement on the reduced diameter extension of a chain pin or, alternatively, on the reduced diameter extension of the thru rod of the conveyor, with the flange of the spool abutting a radial shoulder of the larger diameter portion of the chain pin or of the thru rod, as the case may be, for proper orientation of the spool at a fixed reference location on the chain pin or on the thru rod. The other side plate of the pair of pivotally connected side plates is pivotally movable relative to the spool shoulder although the spool shoulder does not necessarily serve as a bearing for the other side plate. A washer which, in effect, is the opposite flange of the spool, is retained on the chain pin reduced diameter extension, or alternatively, on the reduced diameter extension of the thru rod, at a fixed lateral spacing from the spool flange, whereby to restrict the two pivotally connected side plates to a dimensionally predetermined limited relative lateral movement therebetween, thus minimizing the "wobble" between pivotally connected side plates. |
