Abstract
Vertically stacked drive wheels (17.sub.1, 17.sub.2, 17.sub.3 and 17.sub.4) are provided above a yarn feed wheel (21) which is provided with a first yarn feed surface (27) providing comparatively high friction with the yarn engaged thereby and adaptable for use when the rate of yarn feeding varies, such as in the case of Jacquard pattern knitting, and a second yarn feed surface (28) providing comparatively low friction against the yarn engaged thereby and adapted for use when the rate of yarn feeding is constant, such as in the case of plain knitting. Manually adjustable yarn guide means (29, 30) is provided for selectively guiding yarn to the first and second yarn feed surfaces (27, 28). Clutch members (24, 24') are interposed between pairs of the vertically stacked drive wheels and are selectively operable to impart rotation to the feed wheel (21) from a selected one of the drive wheels.
