Abstract

Some photoreceptors are fabricated from small diameter drums such as 15 mm or 30 mm. During the fabrication of such photoreceptors, an operator may need to hold the small diameter drum. The attached figure discloses a drum holder 2 for grasping the inside of a small diameter drum for manual drum handling operations such as pick and place, inspection, and the like. The drum holder 2 is composed of a handle 12 (preferably knurled), a movable connecting shaft 16 extending through the handle 12, a thumb knob 4 and an extension spring 14 coupled to one end of the shaft 16. An expansion chamfer 8 is positioned adjacent to the handle 12. An expansion chuck 6 having expansion tabs 10 is

DRUM HOLDER (CONT'D)

coupled to the other end of the shaft 16. The operation of the drum holder 2 is now described. The thumb knob 4 is depressed, thus allowing the expansion chuck 6 to disengage from the expansion chamfer 8. The expansion tabs 10 will now deflect inward so the expansion chuck 6 can be inserted into the drum (not shown). The thumb knob 4 is
released and the expansion tabs 10 are expanded by the expansion chamfer 8 (acts as a wedge) where the expansion chuck 6 then grips the inside of the drum....
