Patent ID: 7431285

Claim:
The present invention is a vibratory sheet jogger having a stand to elastically support a sheet tray which receives sheets of paper, the stand having a base cover and body cover, wherein the body cover maintains a plate that supports a DC motor through a DC motor supporting plate, the DC motor plate further elastically connects the base of the sheet tray having an open top end, the invention comprising: a. an eccentric pulley having a cylindrical head coaxially connected with a cylindrical shoulder, wherein the diameter of the head is larger than the diameter of the shoulder, the cylindrical head having an eccentric cylindrical bore where the rotational axis of the bore is parallel to the rotational axis of the pulley head but is positioned at an off-center location relative to the center of rotation of the cylindrical head, said eccentric bore receives the front end of a shaft of the DC motor, said cylindrical head further comprises a screw threaded hole located at an outer cylindrical surface of the head to transversely connect the eccentric pulley by a screw to the motor shaft, the end of the cylindrical shoulder remote from the cylindrical head having a circular slot which receives a lock washer, b. a ball bearing having a central bore inserted onto the shoulder of the eccentric pulley, the ball bearing having a width which is smaller than the length of the shoulder of the eccentric pulley, c. a lock washer to lock the ball bearing onto the eccentric pulley, wherein the lock washer fits onto the circular slot at the end of the shoulder of the eccentric pulley, d. a slotted ring connected to the back of the sheet tray and having a non-round slotted bore located at the center of the ring, the slotted bore has a height and a length, wherein the height approximately matches the outside diameter of the ball bearing, and the length is larger than the diameter of the bearing, the slotted bore is connected to the ball bearing with the eccentric pulley rotated by the shaft of the DC motor; and e. when the DC motor is activated so that its shaft rotates the eccentric pulley, the slotted ring is caused to move up and down in the same vertical direction so that the sheet tray is also caused to move up and down which therefore jogs and separates the sheets of paper.
