    摘要： A thread-cutting apparatus for use on a sewing machine and including a horizontally disposed clipper mechanism positioned transversely of the line of movement of articles through the machine and rearwardly of the stitch-forming mechanism substantially in the plane of the machine''s work support and needle plates. A suction nozzle is positioned beneath an opening in the work support plate, and extends forwardly of the cutting teeth on the clipper blades to draw a chain of stitches into the cutting mechanism to cut a chain adjacent the trailing edge of an article sewn on the machine and again adjacent the leading edge of a subsequent article sewn on the machine. The top blade of the clipper is fixed and forms a continuation of the work support surface defined by the needle plate and work support.

    摘要： A needle carrier for an overseaming machine having a pair of spaced needles aligned in the direction of feed of the workpiece through the machine. The needle carrier includes a head portion having a flat vertical face with an elongated keyway formed therein, and a clamping plate having an elongated key formed on one surface is releasably mounted on the head with the key projecting into the keyway. A pair of grooves are formed in the plate, one on each side of the key, to engage and position the shanks of the pair of needles for clamping between the plate and the flat face on the head portion of the carrier. Any desired needle spacing may readily be obtained by employing a clamping plate having grooves appropriately spaced.

    摘要： A cooling system for an industrial sewing machine of the overseaming type, including a hollow, shell-like shroud positioned over and closely surrounding the sewing machine housing, and a fan mounted on the machine''s main drive shaft adjacent an opening in the shroud to force air through the shroud over the outer surface of the machine and out through open spaces along the bottom of the shroud and at the end of the machine opposite the fan. The shroud being spaced from the surface of the machine is cool to the touch and assists in muffling the sound of the machine.
