发明名称 Vacuum cleaner for sewing machine
摘要 A waste fabric and lint collector and a cut thread chute assembly for use with an overlock stitching type sewing machine, comprising a collector box, including a front wall, two opposite lateral side walls, and top and bottom walls, a large see-through window forming part of the front wall thereof. The collector box is pivotally mounted in a releasable fashion to the sewing machine frame, wherein the front portion of the trimmed fabric and lint outlet is substantially closed by the collector box. A tubular coupling member has an inner end portion of a shape complimentary to that of the top wall of the collector box, for releasable interlocking engagement therewith, and an outer end portion, for releasably coupling with a complementary flexible air suction conduit for discharge of the lint to a waste container. The chute consists of: an elongated tube, having an enlarged transversely opening mouth at one end, and a smaller axially opening outlet port at the opposite end. The chute is anchored at one end to the front edge of the flat-bed of the sewing machine, whereby the tube extends rearwardly beneath the sewing machine flat-bed. The tube outlet port is adapted to be releasably engaged by a flexible waste conduit for gravity-borne discharge of cut fabric threads to a waste container.
