E, indicates the shaft of the motor and F a pinion on said shaft in mesh with a gear G. H, is a pinion on the shaft of the gear G, in'mesh with a gear I, on the generator shaft J. K, denotes'a pinion on the generator shaft in mesh with the lar e time gear L', mounted on thecam shaft %l, which in I turn operates the valve push rods N of the engine. Y P, denotes a small time gear mounteduponthe engine crank shaft Q, in mesh with the large tlme gear L.

The usual case of the large time gear employed on the Ford engine is divided. along the line B, and to this is secured the caseof the starting unit by the bolts D, pregear viously indicated.
