Abstract
A sheet jogging device includes a compact housing having an inclined front face, and a rack resiliently mounted to said housing along said front face. Within the housing a drive spring is fixed at one end to the housing and connected at an opposite end to the rack. An electromagnet is mounted beneath the drive spring to exert an oscillating magnetic force on the drive spring to flex the drive spring about its base to reciprocate the rack along the inclined face of the housing.
Claims10
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.

A vibratory sheet jogger comprising:
- a housing having a base plate, a pair of sidewalls extending upwardly therefrom and defining therewith, a rearwardly tilting open front face extending up from said base plate;
- a rack positioned at said open front face having a rearwardly tilting back plate, said back plate for guiding an edge of a stack of sheets, said back plate being parallel to said front face;
- at least one elastomeric spring member mounted on said sidewalls of said housing, said rack being connected to said spring member for connecting said rack to said housing;
- and
- an electromagnetic drive mounted on said housing between said sidewalls, and operative to oscillate said rack with respect to said housing,
- said electromagnetic drive including a cantilevered drive spring having a base end mounted on said housing by a spring mounting bar extending between said sidewalls of said housing, said drive spring extending from said spring mounting bar and having a distal end in engagement with said rack,
- said electromagnetic drive further including an electromagnet mounted on said housing between said base plate and said cantilevered drive spring.
