Abstract:
A vibratory sheet jogger, comprising:a housing having a base plate and a pair of sidewalls extending upwardly from said base plate and defining therewith an open front face; a rack positioned at said open face of said housing; at least one spring member mounted on a spring mounting plate extending between said sidewalls of said housing, said rack being connected to said spring member for connecting said rack to said housing; a drive spring having an elongated body being substantially fixed at a base end to said housing by a spring mounting bar extending between said sidewalls thereof, and engaged at a distal end thereof to a drive block on said rack; an electromagnet mounted on a support plate extending between said sidewalls of said housing and arranged on one side of said drive spring and located to have an air gap between said electromagnet and said drive spring, said air gap small enough for said electromagnet to exert a magnetic force on the drive spring to deflect said drive spring about said base end to move said rack in opposite directions as the magnetic force on said drive spring oscillates.
