Patent ID: 8051972

Claim:
A conveyor comprised of: a base plate having a first end and a second end; a transporting tray resting on top of the base plate; a driving means connected to the first end of the base plate and connected to the transporting tray, the driving means being comprised of: a first end plate having a first front face and a first back face; a second end plate having a second front face and a second back face; one or more carriage guide pins, at least one of the one or more guide pins being connected between the first front face and the second front face; a sliding carriage frame positioned between the first front face and the second front face, wherein the sliding carriage frame substantially rests upon the one or more carriage guide pins; at least one spring connected at one end to an inner wall of the sliding carriage closest to the second front face and connected to at a second end to a tension adjusting collar; a solenoid connected to the base plate, connected to a bumper, and positioned within the sliding carriage frame; and a switch connected to a power source such that when the at least one spring is in a expanded position, the switch and solenoid are substantially adjacent to each other; wherein as the switch is in a closed position when the sliding carriage frame is closest to the second front face and the spring is in an expanded position, the solenoid is energized thereby driving the bumper into the sliding carriage frame and moving the sliding carriage frame in a direction of the first front face until the compressed spring directs the sliding carriage frame back towards the second front face, the reciprocating motion of which causes pulsating movement of the transporting tray that moves desired materials in the tray away from the driving means.
