  • Patent number: 6182589
    Abstract: A driving apparatus for an oscillating catcher of a sewing machine includes a toothed pinion being eccentrically mounted on a driving shaft for the catcher for the sewing machine. A transmission device, having teeth, is guided in a back-and-forth movement by an oscillating crank drive, with the teeth of the transmission device engaging the tooth pinion on the driving shaft. By arranging the toothed driving gear eccentrically on the driving shaft of the catcher, it is possible to substantially increase the speed of the point of the catcher when it seizes the loop of the upper thread offered by the needle.
