ABSTRACT:
This invention is directed to an improved eccentric crank assembly for a reciprocating piston type air compressor. The eccentric crank assembly includes an eccentric plate, a compressor shaft, and an eccentric shaft. The eccentric plate is provided with a pair of parallel overlapping openings formed therethrough. The compressor shaft includes one end provided with a flat angled surface, and the eccentric shaft includes one end provided with a corresponding flat angled surface. The angled surface ends of the shafts are disposed within the openings of the plate. When the eccentric shaft is moved away from the compressor shaft, the angled flat surfaces force the shafts radially apart and into engagement with the openings of the eccentric plate, thereby locking the shafts and the eccentric plate together.
