An assembly for use in combination with sewing machines for purposes of removing portions of stitchable material around which a buttonhole or other desirable design is sewn by the sewing machine. In one embodiment, the assembly is a kit which includes a support assembly, a material removal device positioned within the support assembly, and a driver connected to the material removal device to supply the necessary forces to remove portions of material. The kit assembly may be attached to a sewing machine without requiring any substantial modification thereof and, if properly positioned, will not interfere with sewing operations and the components associated therewith. The kit assembly may also be removed or disabled to allow the sewing machine to perform functions other than sewing buttonholes. In another embodiment, a portion disposal system is utilized to carry away and preferably contain the removed portions of material.

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.

A container includes a cover body and a holding body, and is removably mounted on a needle plate of a sewing machine including a horizontal shuttle. The horizontal shuttle includes an inner shuttle that includes a bobbin containing portion. The cover body is plate-shaped, is removably mounted in the needle plate in a position above the horizontal shuttle, and includes a through-hole and a first face that occupies the same plane as a top face of the needle plate when the cover body is mounted in the needle plate. The holding body is disposed inside the bobbin containing portion and includes a side wall and a bottom wall. The side wall encircles an area of a second face in which the through-hole is formed. The second face is a face on the opposite side of the cover body from the first face. The bottom wall is opposite the second face.
