A conveyor system (1) with a support apparatus for maintaining non-pendular substantially straight-line motion of the material-conveying member (5) thereof, wherein the support apparatus includes straight-line linkage (18, 1 9) which is mounted between a rigid supporting surface (23) and the material- conveying member (5) so as to restrict movement of the material-conveying member (5) to a substantially straight-line non-pendular path parallel with the path of conveyance. Each straight-line linkage assembly (18, 19) which supports the material-conveying member includes a set of three linkage arms (39, 41, 43) which are pivotally interconnected with resilient bushings (45, 46, 52, 54, 56) that continually urge the linkage to a central neutral or resting position during movement thereof. Two of the linkage arms (39, 41) a re pivotally connected in spaced relation at one end to a rigid support (21), a nd are each pivotally connected at their opposite end to a third intermediate linkage arm (43) which is disposed therebetween.
