A plain flanged bearing or bushing for supporting a rotating shaft in a thin walled frame of an electrophotographic printing machine. The composite bearing has a flanged end and is adapted to be inserted in an opening in a thin walled support member until the flange abuts the surface of the wall. A protruding tab formed by displacing a small portion of the flange extends in an axial direction along the bearing and cooperates with a corresponding opening in the wall to prevent rotation of the bearing. A friction push nut or snap ring is attached to the bearing on the side of the wall opposite the flange. The protruding tab prevents the bearing from rotating about an axis which can cause the bearing to be worn on the exterior surface by rotational contact with the thin wall. A shaft to support idler rolls or other rotating elements is inserted in an inner bore of the bearing and is rotatably supported thereby.

Composite flanged bearing having anti-rotation feature

An auger for use in a xerographic development system comprising an elongated twisted unitary strip of sheet metal, defined by two helically contoured edges extending along the longitudinal axis of the auger. The auger contains a series of spaced apart slots or recesses along the outer periphery of the helical edges, the slots extending inwardly a short distance from the edges toward the axis of the auger.

Auger for a development system

An article such as a collar having a setscrew for enabling securing the collar on a shaft member which is telescopically received in an opening of the collar characterized by the collar having a pair of cavities with one cavity in communication with the opening and extending from one end and the other cavity extending from the opposite end and in communication with an outer surface of the collar. Each of the cavities terminates in a partial annular threaded segment which segment coacts to form an opening having interrupted threads to receive a setscrew. The threads on each of the annular segments extends transversely to a direction of application of pressure when forming the collar such as by compacting metal powder which is subsequently sintered.
