658. Butterfield, W. H. Jan. 9. Force-feed lubricators.-The lubrication of an internal-combustion engine, particularly of the two-stroke-cycle type, is effected by suction caused by changing pressure in the crank chamber. A system of connected passages in the crank-shaft, crank, connecting-rod, and gudgeon pin is open to the crank chamber through an orifice 13<a> beneath the piston. Oil is supplied by a pump or other means to a groove 2 in one of the crank-shaft bearings, and when the piston is rising the oil is sucked through the passages to lubricate the connecting-rod bearings and, through the gudgeon pin, the cylinder. On the downward stroke of the piston, a radial passage 6, Fig. 2, in the crankpin is out of register with a groove 7 in the connecting-rod 9, and the return of the oil is thus prevented. Specification 659/12, [Class 12(ii), Lubricating passages &c.], is referred to.
