Abstract
The wear life of knitting machine instrumentalities, such as knitting needles, sinkers, or the like, is increased by providing a reinforcing wear-resistant plate member on the operating butt portion thereof to effectively increase the thickness of the operating butt portion. The wear-resistant plate member includes a cam engaging edge extending along the cam engaging edge of the operating butt portion with the cam engaging edge being inclined at an angle corresponding to the inclined angle of the operating cams of the knitting machine which it is adapted to engage. A beveled edge extends along the junction of the cam engaging edge and the face of the adjacent operating butt portion to form a groove defining an oil retaining sump between the plate member and the operating butt portion for temporarily retaining lubricant therein and for providing lubrication between the operating butt portion and the operating cams.
