A ring oiling bearing has a reservoir of oil underneath the shaft, or journal, into which a ring resting on the upper side of the shaft is allowed to dip, and as the shaft rotates the oil is carried up onto the shaft, where it spreads out to each side, thoroughly lu- bricating the bearing. Such a bearing is very desirable for a machine in continuous service. Inclosed Wheel Boxes. It is customary on the best machines that are to be subjected to much dust, to enclose the outer end of the wheel boxes and provide a collar at the inside end of such a construction as to practically exclude all dust. The lubricant is usually "hard oil" or heavy grease,.
