 Fig. 9 shows a section through mainrbearing. The quarter boxes with their wedge adjustments are clearly shown, as are also the oiling chain and oil reservoir, by means of which the bearing is kept constantly lubricated. The oil gauge indicates at any time the height of oil in the reservoir and enables the engineer to tell at a glance how much oil he has to depend on.

Fig. 10 shows a horizontal. section of the bearing, and is intended to outline how the oil is conveyed back to the reservoir after having been lifted by the chain and spread over the bearing; it is returned through the oil drains that run from the ends of the bearing to the center.

Figs. 11, 12, 13 and 14 represent different views of the crosshead. This is a solid steel casting supported on slippers, faced with the best anti-friction metal. All wearing surfaces of this crosshead are faced with this material, and the excellent results obtained in practice testify to its very superior anti-friction qualities. The head is screwed on to the rod and a "marine" nut is used to jam it. The illustration depicts the manner of holding so well that any further explanation is unnecessary.
