ABSTRACT:
There is provided a mechanism or system for use with a motor driven mechanism, such as a pump for pressurizing paint for spray painting purposes, which permits conversion of the power source therefor between an electric motor and an internal combustion engine, each of which being capable of directly driving the motor driven mechanism. The mechanism or system includes a commonly shared clutch mechanism which is controlled such that the clutch is engaged and the pump operated until the operating level is reached at which time the clutch is disengaged so that the electric motor or internal combustion engine is under no load. The clutch mechanism utilizes a magnetic clutch and the clutch driven plate is non-rotatably connected to the pump input shaft while the clutch drive plate in non-rotatably connected to the motor or engine output shaft. The clutch drive plate is splined or keyed onto the engine or motor output shaft and is interchangeable between the output shafts of the electric motor and internal combustion engine. The electromagnetic coil, when energized, magnetically draws the clutch drive plate towards the clutch driven plate and causes the two plates to engage with one another.
