    摘要： The sewing machine includes a drive shaft which is rotatably mounted in a housing and is connected to a needle to reciprocate the needle at a stitching area in order to effect sewing of material. A fan blade or impeller is affixed to the main shaft for rotation therewith, and it rotates in a chamber in the housing and is constructed with a central inlet opening to pull in air centrally and to discharge it radially downwardly into a lower extension below the oil pan of the sewing machine. The lower extension includes a plurality of ribs extending downwardly from the bottom wall of the oil pan which forms heat exchanger surfaces over which air from the blower is directed. The heat exchange surfaces are arranged in the form of longitudinally extending ribs which extend substantially parallel to the shaft and they define air flow channels therebetween.

    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.
