Abstract
991,955. Sewing machines. NECCHI S.p.A. Sept. 27, 1963 [Oct. 25, 1962], No. 38155/63. Heading D1G. [Also in Divisions F1 and F2] In a lubricating device for sewing machines having a reservoir 5 for oil, means for distributing the oil from the reservoir to the parts to be lubricated, a sump 35 for the oil and a suction-pump 74 for re-conveying the oil from the sump to the reservoir, the suction-pump has a bushing 75 which is located in the vicinity of the reservoir and above the oil 4 therein and which supports a shaft 2 having an annular groove 80 connected to left and right hand helical grooves 81, 82 therein. Suctionducts 73, 85 are provided in the bushing 75 and are connected, one to the sump and the other to the reservoir. The bushing 75, having an extension 76, has its axial movements limited by a pin 79 which is fixed to the reservoir 5, the amount of axial movement permitted being sufficient to allow the annular groove 80 in the shaft 2 to be aligned with the ducts 73, 85 in the bushing. In use, oil is first sucked from the reservoir by the grooves 81, 82 in the shaft 2 so as to prime the grooves and the oil is then pumped from the sump 35 to the reservoir 5. The suction of the pump is facilitated by a spring 86, Fig. 5, which is located between the bushing 75 and the reservoir wall. A felt 66 in the sump 35 serves as a filter; a disc 3, which is integral with the shaft 2, lifts oil from the reservoir and wicks convey the oil from the disc 3 to some of the parts requiring to be lubricated, and other parts are lubricated by an oil mist which is created by swiftly moving members of the sewing machine.
