Abstract

26,994. Fisber, H. J., Dec. 6. [Cognate Applications No. 2518, A.D. 1908, dated Feb. 4, and No. 11,534, A.D. 1908, dated May 27.] Link-work.-The piston of an internal - combustion or other engine is so connected to the crank that the piston remains stationary until the crank has advanced to an advantageous angle. In one arrangement, the gudgeon pin d, Fig. 2, is carried by a cross-head k sliding on rods e, which are secured to the piston and slide in guides e' on the cylinder. The pin d carries cams f, which act on levers p pivoted to the cross-head and acting on the piston. In a modification, shown in Fig. 6, the gudgeon pin d slides in guides e<2>. An eccentric g is mounted on the gudgeon pin, the strap being pivoted to the piston at h<1>. The eccentric may alternatively be mounted on the crank pin. Another device consists in the use of a bell-crank connecting-rod, as shown in Fig. 8, driving a crank-shaft which is displaced laterally. The bell-crank l is pivoted at l<1> to a cross head m, sliding in the piston, or in the cylinder, or on other guides. The short arm of the bell-crank is linked to the piston. A further modification consists in the use of a telescopic connecting-rod acted on by pins on the crank-pin or on the gudgeon pin. Fig. 11 shows a connecting- rod consisting of a part o<1> pivoted to the crank-pin, and a part o sliding on the part o<1> and acted on against the pressure of a spring by cams r on the crank-pin.
