Abstract A corona charging device and support arrangement in which the main structure is supported on a rail which is movable vertically toward or away from a supporting base by means of a pair of plate springs adjacent each end of the rail, each spring having one end thereof attached to the supporting base and the other end thereof fixed to the bottom plane of the rail near one end thereof. The corona discharge structure is movable horizontally in the longitudinal direction of the corona structure along the rail by means of a tongue-in-groove arrangement. In addition, the supporting rail is movable toward and away from a photosensitive surface by means of a pair of set screws mounted on the supporting bases which, when rotated, bear against the bottom of the plate spring and move it and the rail attached thereto in the direction away from the support base and toward a photosensitive surface.

Claim 1
Independent Claim
201 words
In combination, a corona charging device comprising an elongated shield defining a chamber generally concave in cross section and having an opening on one side thereof and a wire electrode supported along the longitudinal axis of said shield by insulating blocks supported at opposed ends of said shield, an imaging surface adjacent said opening and adapted to be charged by said device, a support arrangement for permitting movement of said device in directions parallel and perpendicular to said axis, said arrangement including a rail extending parallel to the longitudinal axis of said shield, said rail including outwardly diverging flanges, said shield including a channel on the side thereof opposite said opening, said flanges interfitting into said channel so as to permit sliding movement of said shield along said rail generally parallel to said axis, a compression spring interposed between said rail and said device to continuously bias said shield away from said rail, a fixed support base, a leaf spring coupled intermediate said base and said rail, a set screw carried by said base, said set screw movable perpendicular to said axis for flexing said leaf spring, whereby movement of said device in a direction perpendicular to said axis is accomplished.
