Abstract: A device for automatically offsetting pronged fasteners, or staples, in successively fastened sets of sheet material is provided. The assembly may be disposed within any manual or power driven stapler. It may comprise a manually or electrically rotatable drive gear which, when rotated, pushes a means for setting the depth at which such fasteners may be delivered into such sheet material respective to an edge thereof. In use, stacked sheets of material, such as paper, may be placed within a stapler. Then, when the stapler is activated to fasten the set, the drive gear may automatically rotate to push the means for setting the depth forward so that a subsequently delivered fastener may be delivered into a following set of sheet material at a different depth from the edge of the prior set.
