Abstract
A circular knitting machine is constructed for facilitating replacement of the needle cylinder and dial element without the necessity of hoisting the dial by means such as a chain block. The circular knitting machine includes a circular dial element supported adjacent the opening in the upper end of the needle cylinder. A rotatable drive shaft is supported at the upper end of a frame support member and extends downward to a position adjacent the circular opening in the upper end of the needle cylinder. A vertically extending support sleeve surrounds the drive shaft and is supported at the upper end on the frame support member for telescopic vertical movement relative to the drive shaft. The lower end of the support sleeve is fixed to the dial for supporting same. A dial control is provided for lifting and lowering the support sleeve along the drive shaft to lift the dial element a sufficient distance to permit removal and replacement of the needle cylinder.
