Abstract:
1. An apparatus providing controlled blade engagement with an associated image forming machine moving surface comprising: a first elongated blade having a first pin disposed at a first end and a second pin disposed at a second end opposite the first end; a second elongated blade having a third pin disposed at a first end and a fourth pin disposed at a second end opposite the first end; a pair of spaced apart support members disposed in a facing relationship at the first and second ends of the first and second blades, the support members each having a first track slot receiving the first blade for sliding movement towards and away from the associated image forming machine moving surface and a second track slot receiving the second blade for sliding movement towards and away from the associated image forming machine moving surface; a pair of spaced apart links including a first link disposed at the first ends of the first and second blades including a rigid body having a first slot receiving the first pin and a second slot receiving the third pin and a second link disposed at the second ends of the first and second blades including a rigid body having a first slot receiving the second pin and a second slot receiving the fourth pin; an actuator rotating the first and second links in a first rotational direction moving the first blade along the first track slots and into a working position engaging the associated image forming machine moving surface, the actuator rotating the first and second links in a second rotational direction moving the second blade along the second track slots and into a working position engaging the associated image forming machine moving surface.
