Abstract
A conveyor system with a support apparatus for maintaining non-pendular substantially straight-line motion of the material-conveying member thereof, wherein the support apparatus includes straight-line linkage which is mounted between a rigid supporting surface and the material-conveying member so as to restrict movement of the material-conveying member to a substantially straight-line non-pendular path parallel with the path of conveyance. Each straight-line linkage assembly which supports the material-conveying member includes a set of three linkage arms which are pivotally interconnected with resilient bushings that continually urge the linkage to a central neutral or resting position during movement thereof. Two of the linkage arms are pivotally connected in spaced relation at one end to a rigid support, and are each pivotally connected at their opposite end to a third intermediate linkage arm which is disposed therebetween. The third linkage arm, in turn, is pivotally connected to the material-conveying member in supporting relation, and the set of three linkage arms are constructed and positioned in such manner as to cause the material-conveying member to reciprocate in non-pendular motion along a substantially straight-line which is parallel to the path of conveyance when excited by vibrational forces along such path.
