ABSTRACT:
A looper lubricating device for a sewing machine includes an oil line having an inlet submerged within an oil supply and a capillary member within the oil line at a spaced location from the inlet and the oil supply. An outlet of the oil line is in fluid communication with an injection nozzle and the capillary member protrudes through the outlet of the oil line into a mixing chamber within the injection nozzle. A gas conduit communicating with the mixing chamber is operative to intermittently produce a pressure gradient between the inlet and the outlet of the oil line to pass oil to the mixing chamber.
