DIAGONAL DIRECT-ACTING ENGINES. 203

pression, or too early an exhaust. The space usually occupied by
eccentrics on the crank shaft is saved, and thus the cylinders and
the cranks, as well as the main bearings, can be brought much

At a joint, J, on the connecting-rod, C R, is attached a double
link, L<sub>1</sub> L<sub>1</sub>, about 1/3 along this double link is attached a pair of
