ABSTRACT:
A dust collector for a sewing machine includes a dust collector box secured to a motor housing having a blower motor and a clutch motor disposed in axial alignment with each other. Suction hoses lead from the vicinity of the sewing machine to an inlet for the box and the outlet of the box is provided with a filter whereby a clean stream of air exiting from said box will pass over the motors to cool the same. The treadle operated control lever for the clutch for energizing the sewing machine is provided with a switch adapted to be closed upon engagement of the clutch and opened upon disengagement of the clutch. The switch is connected in series with a selective control switch for the blower motor whereby when the switch is in a first position the blower motor will be energized simultaneously with the engagement of the clutch and deenergized simultaneously with the disengagement of the clutch. When the switch is in a second or third position, the blower motor may be turned off or on independently of the clutch engagement.
