Abstract
746,008. Sewing-machines. SINGER MANUFACTURING CO. May 20, 1954 [June 1, 1953], No. 14800/54. Class 112. [Also in Groups XXVI and XXXIV] Lubricating.-The bed-shaft 12 is mounted in bearings 13 . . . 16 and provided at one end with an axial bore 42, and lubricant is delivered to this end and fed along the bore as the shaft 12 rotates, by means of a helical spring 49, and thence through radial holes 43, 44, 45 to bearings 46, 47, 48. The shaft 12 is formed with a crank 19 for actuating a connecting rod 20 which is provided with a lubricant splasher 21 dipping into lubricant in a sump 22. As the shaft 12 rotates, the splasher distributes lubricant within the standard 11. Some lubricant collects in a trough 23 and flows into a fitting 24 which supplies a main tube 25 for distribution to tubes 29, 30, 31 leading to bearings. The tube 30 at one end is provided with a wick which extends into a fitting secured to the bearing 16 and supplies lubricant through an opening in a bushing 33 surrounding the end of the shaft 12. One end of the bushing is closed by a cap 40, and a chamber 41 is formed between the end of the cap and the end of the shaft 12, the chamber being partly filled by a wick 50 which is coiled around the spring 49. The spring is fixed at one end to the cap 40. As the shaft rotates the spring 49 acts as a screw pump to force the lubricant along the bore 42. A helical groove 56 is formed on the outer surface of the shaft 12 to prevent escape of lubricant along the inner surface of the bushing 33.
