Abstract
534,428. Sewing-machines. FAIRWEATHER. W. C. (Singer Manufacturing Co.). Feb. 22, 1940, No. 3320. [Class 112] Oil, supplied by a pump to a conduit 22, passes around the hook shaft 17 by an annular space 24 into a chamber 26. From the chamber it passes into an eccentrically located annular space 28 and into a bore 30 in the hook shaft containing a removable filter 34. Oil leaves the filter by passages 36 and is transferred to the spool case race 40 by passages 39 and surface 41. The end of the chamber 26 is partly closed by means of an apertured disc valve 44 which can be turned to vary the oil leakage from the end of the chamber. In place of the disc, a conical ended screw may be used as a valve.
