Claim Text:
1. A vibratory conveyor, comprising: a base frame mounted on an adjacent supporting surface; a multiplicity of elongated springs mounted on the base frame, and where each of the elongated springs have a distal end; a reciprocally moveable conveyor bed which is mounted on the distal end of the respective elongated springs, and which further is supported for reciprocal motion relative to the base frame, and wherein the reciprocally moveable conveyor has a center of mass, and wherein the base frame, and the reciprocally moveable conveyor bed each have a given weight, and wherein the respective weights are in a ratio of about 3:1, and which constitutes a design point for the vibratory conveyor; four unbalanced motors which are mounted on the base frame, and which, when selectively energized, generates a vibratory force which is oriented along a line of force, and which passes through the center of mass of the reciprocally moveable conveyor bed, and wherein the vibratory force causes the reciprocally moveable conveyor bed to reciprocate, and have a variable stroke, and which effects the movement of a product, at a selectively variable speed along the reciprocally moveable conveyor bed, and wherein the four (4) unbalanced motors can be selectively energized in pairs, and the pairs of unbalanced motors can be energized in a manner so as to cause the reciprocally moveable conveyor bed to reciprocate relative to the base frame, and in a fashion which is below the design point; at the design point; and/or above the design point of the vibratory conveyor, and wherein in a first mode of operation the unbalanced motors are selectively energized so as to create a vibratory force which is below the design point of the vibratory conveyor, and which further causes both the reciprocally moveable conveyor bed, and the base frame to reciprocate, in-phase, and in an amount of about 2 mm.
