Abstract: In order to provide the capability of distributing a material that is conveyed, a vibratory distribution conveyor includes a deck having a distribution edge. The distribution edge extends between an inlet end and an end remote therefrom and the deck is subjected to vibratory motion to cause material to be conveyed from the inlet end toward the end remote therefrom. With this arrangement, the declination of the deck is controlled about a longitudinal axis to control the distribution characteristics of the conveyor.

Abstract: A spring support bracket for supporting a sheet metal trough intermittently on leaf springs provides an L-shaped bracket for a welding connection to a side wall and bottom wall of the sheet metal trough and a spring block extending outwardly from the vertical member of the L-shaped bracket and tilted to the vertical rearwardly of the trough. The spring block includes an aperture for receiving a fastener for connecting a leaf spring thereto so that the trough may be supported by a plurality of leaf springs arranged intermittently along the length of the trough and on opposite lateral sides of the troughs.

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.

Abstract: A vibratory conveyor arranged so that the vibrations have a substantially greater horizontal than vertical movement. More particularly, the vertical acceleration of material carried by the material-carrying member is less than the acceleration of gravity and therefore the material conveyed does not physically leave the surface of the material-carrying member. The result is a smooth flow of material from one end of the material-carrying member to the other.
