To adapt these engines to electric traction service, prob-ably the best arrangement would be to have the four ver-tical cylinders in line, each with a double crankshaft, thecrank of each outer cylinder being set at 135 degs. to thatof its adjoining inner cylinder and the cranks of the twoinner cylinders at 90 degs. with each other. This wouldgive eight impulses in each revolution, as in the Manhat-tan engines. Two alternators might be used, one at eachend of the shaft, each of half the power of the engine unit,or if it is practicable to build one alternator of sufficientcapacity to utilize the total power of the engine, it mightbe set between the two inner cylinders. In the latter casethere need be only two double cranks, single cranks withoverhung pins being ttsed for the outer bearings, and onlyfour main bearings would be needed, while in the formercase there would be f
