IMPROVED COROTRON ELECTRODE Proposed Classification HOLDING DEVICE U.S. Cl. 250/324 Donald A. Seanor mt. Cl. HOlt 19/04

This disclosure relates to a spring loaded, retractable holder for corotron electrodes of the type used in corona-charging devices. Exemplary of prior art supports used for mounting the corotron electrode are those described in U.S. Patent No. 3,983,393 and U.S. Patent No. 4,086,650. The spring loaded, retractable corotron electrode holder of the present disclosure operates on the principle of a retractable ball point pen.

In a retractable ball point pen, the retractor is pushed and engages. After pushing

the retractor again, the retractor comes out of the body of the pen and in this position it is spring loaded. This mechanism is used for loading and charging the corotron electrode (wire) in corona-charging devices.

Referring to the drawing, the fixed live end block for mounting the corotron

electrode (such as a tungsten wire) is designated by numeral 1, and the movable end block connected to a retracting device is designated by numeral P. End block P is pushed in the direction of support block 1 to engage, and in this position, corotron electrode 2 is loose and may be inserted into or removed from the holder therefor in end block 1', By again pushing end block P, the retracting device is disengaged, and the biasing member (spring) in retracting device 10 pushes support block P in

the direction away from end block 1 and...
