In Fig. 50 is shown, in the same class of engine, the system of automatic lubrication employed. This may be described as follows: Centrifugal force, derived by the motion of the discs, delivers the oil into oil cups and main bearings. It is then forced to the crank-shaft bearings and returned to the oil chamber under the crank disc, as clearly shown by cut. The holes through which the oil passes to the crank are one-half inch in diameter; therefore not easily stopped up. They are straight throughout their length, to permit of their being conveniently cleaned. The crank discs are covered by a light dust-proof hood, fitted to the top of the engine frame, entirely without bolts or other fastenings of any description. This hood is built in a unique form, and is really oil-tight. It is readily removable. An oil-tight side plate encloses the crosshead and guides, and affords ready access thereto. No oil can possibly get to the belts or floor. The unique construction of main bearings ensures a minimum amount being drawn to the fly wheels, and any oil finally escaping is caught and held by the flanges thereon; only enough oil should be supplied that the crank disc will dip about an inch into it. A greater quantity is not desirable, as it will cause a churning action. The oiling system in this engine is most cleanly and thoroughly efficient. |
