This action will of courseI take place if the car 2ris tised as the controlling ear, for the purpose of starting the engine 3..

The electro-magnetically released brakes indicated i1t 38, B9 on the controller shafts are proviid for the pur ose of causing the' controllers to assume de mite positions and maintaining them inA these positions. The

' actuating coil of thebrake 3S is included in' Vactuatin the circuits from the battery 60 which in clude the magnets' 41 'and 42 so that whenever one o'r other of these. magri-ets l.is e'nergized to cause the clutch regulator 19 to vary the position of the controller 29, the coil of the `brake 3.8 will also be energize and release the brake and allowv the controller 29 to be moved. As soon as t- lie magnet 41 or 42 as the case. may be is denergized, Whihvwill occur when thecontroller has been mvedf-fvtellicdesired pos'ition, the brake coil, 38 will alsow'b'il'c'energized -with the result tha't the bra-ke will be applied and stop further movement of the controller` The coil of the brake't) is Ainh4 eluded in circuit with the magnets 45, 40 and this brake, acts in a similar manner on then controller 80. In order to prevent too rapid acceleration of the traction motors'33, 34 'when the master controller is moved fromits case their actuating coils are included as, usual 'in the motor c1rci1it.

If, however, they speed of' the engine 4 increases 'the circuit of the electro-magnet .101' Wil be intersi rupted more. frequently than that of the electroinagriet 100, so that the ratclietaivheelv 105 will-be. rotated at a greater speed than v.the ratchet Wheel 104.
