Abstract
A sewing machine, comprises a sewing machine head with a needle bar bushing supported in the head and a needle bar engaged in the bushing for upward and downward axial movement. The sewing machine includes an oil pan below the head and a scraping wick is engaged around the bar in the bushing and bears against a reabsorbing wick which extends from the scraping wick to the oil pan. The head is advantageously provided with a head cover which covers a recess having a pad which engages against the reabsorbing wick and biases it into contact with the scraping wick. In addition, the construction includes an additional wick which extends in an axial direction from a location above the scraping wick to a location at the lowermost end of the bushing and it is located between separated ends of the scraping wick and provides an oil-conducting connection with the scraping wick.
