ABSTRACT:
To allow a lathe to turn the photoreceptor drums, charge rollers and developer brushes of printers, copiers, and facsimile machines, a unitary component adapts the object so it can be held on the lathe and drives the object. The adapting portion includes a flexible material such as a hose or o-ring to snugly receive the end extension of the drum, roller or brush. The drive portion connects with the drive bolt of the lathe and spins the object. In a second embodiment, the drive and adapter portions are separate components. A bore in the drive bushing is lined with a short piece of hose or one or more o-rings and snugly receives a protrusion from the adapter unit. A third embodiment replaces the drive bushing with tail stock forced against the adapter unit by the drive bolt of the lathe. A bore in the adapter unit lined with a flexible hose or o-ring snugly receives the end of the tail stock. A fourth embodiment of the invention provides an adapter unit which is received in the drive bushing and which may hold a different sized drum, roller or brush end extension by turning the adapter unit end for end. A fifth embodiment of the invention provides an adapter unit which has a portion received in the photoreceptor drum. A piece of flexible material is forced between the adapter unit and drum.
