the generated electromotive rents. As a second function, combined withthe first, the commutator acts in its entirety flows through the primary winding 14, thereby inducing current in the secondary 15 and causing a spark in the usual manner at the plug 26.

The foregoing describes the system employing the battery as a source of--current, this usually being the case when the magneto is being slowly revolved, as when starting the engine. When it is desired to use the current generated by the magneto and cut out the battery, handle 27 may be pushed in one notch thereby moving it from the spring stop '28 where lever 11 is held when battery is employed, to the spring stop 29. Thismoves plate 9 carrying the commutator, to the left, as shown in Fig. 2, thereby withdrawing the commutator segments 7 and 8 from the brushes 4 and 6, and also withdrawing plate 9 from brush 5. This operation disconnects the battery from the circuit, and the magneto is now free to op; crate. To stop the magneto current, handle 27 is pushed in to the extreme right-hand spring stop 30, which grounds stem 21 oh a suitable contact 31, thereby short-circuit? ing the primary winding 14: and interrupter contacts 16 and stopping the generation of current.

It will be observed that since the battery commutator is entirely out of contact with the brushes, no mechanical wear takes place when the battery is not actually in use,

With this understanding of the details of my invention, it will be clear that the commutator, as one function, reverses the battery connection with respect to the interrupter and primary winding of the magneto,

as the rotor turns through each half revolution, whereby the battery current always flows through the primary winding in direction to be augmented (and not opposed) by the currents being generated by the magneto. The commutator segments are geared to the rotor in proper angular relation so that they pass battery current in phase with forces or curas a. switch to disconnect the battery and stop the mat'hiue.-

While I hav shown my invention embodied in a switch mounted in connection with the usual interrupter casing, on one end of the magneto, I do not wish to confine myself to this location for the switch as it may be mounted anywhere about the magneto. Instead of brush contacts, the switch may consist of spring members suitably operated by any form of rod or lever, it being understood that my invention consists broadly of a combination with the usual magneto, of a switch mechanism mounted on or in connection with the magneto and adapted to be suitably operated thereby. \Vhen the switcn mechanism is mounted on the magneto instead of at a remote point, intermediate connections are wholly eliminated as above set forth.

Having thus described my invention what I claim and desire to secure by Letters Patent is- 1. An ignition system comprising a dynamo and a battery, an induction coil common to both, said coil being normally connected to derive current from the operation of said dynamo, and a combined commutator and switch driven in synchronism with the dynamo and controlling the connection of the battery with said induction coil so that when its switch contacts are closed the battery current and the dynamo current will augment and not oppose each other.

'2. An ignition system comprising a dyname and a battery, an induction coil common to both, said coil being normally connected to derive current from the operation of said dynamo, and a combined commutator and switch driven in synchronism with the dynamo and controlling the connection of the battery with saidinduction coil with means to close and open the commutator switch contacts to connect and disconnect the battery to and from the dynamo and coil, respectively.

3. An ignition system comprising a dyname and battery, an induction coil common to hot said coil being normally connected to derive current from the operation of said dynamo, and a combined commutator and switch driven in synchronism with the dynamo and controlling the connection of the battery withsaid induction coil with means to move the commutator as a unit so as to open'its contacts andydisconncct the battery from the coil, and a separate contact adapted to be closed by continuing said movement, so as to disable the dynamo.

4. An ignition system comprising a dynamo and a battery, an induction coil common to both, said coil being normally connected to derive current from the operation of said dynamo, and a combined commutator and switch driven in synchronism with the dynamo and controlling the connection of the battery with said induction coil with manually controlled means for opening the commutator switch contacts to disconnect the battery at will.

5. An ignition system comprising a dynamo and a battery, an induction coil common to both, said coil being normally connected to derive current from the operation of said dynamo, and a combined comnected to derive current from the operation of said dynamo, and a combined commutator and switch driven in synchronism with the dynamo and. controlling the connection.

of the battery with said induction coil with means to shift the commutator into any one of three separate positions, in the first of which the battery is connected with the induction coil through the commutator as described, in the second the battery is dis connected from the induction coil by separation of the contacts of the commutator and the coil is supplied with energy by the dynamo alone, and in the third position the dynamo is disabled.

7. In an ignition system in combination, a dynamo excited primary winding, a battery, interrupter contacts arranged to intermittently short-circuit said primary winding, a commutator driven in synchronism with'said dynamo and through contacts of which said battery is connected with said primary, winding and said interrupter contacts, means to shift the commutator contacts to disconnect the battery from the winding and interrupter contacts but to leave the dynamo connected there said contacts and said winding.

8. In an ignition system a dynamo and a battery having a common induction coil and a combination commutator switch unit through which the battery is connected with the primary winding of said-induction coil, said unit being mounted upon said dyna mo and having its commutator contacts driven by the, rotating element thereof.

10. In combination a magneto electric machine having generating windings, a polarity with, and additional means to shunt circuit reversing commutator normally dissociated from said generating windings and having an element mounted for anal reciprocating movement, together with means to reciprocate said commutator element axially and shuntcircuiting contacts associated with said gei'ierating winding and arranged to be closed through'the axial movement of the commutator element.

12. In combination a dynamo excited induction coil, dynamo operated interrupter contacts, and a normallyppen shunt-circuit for the primary winding of said coil all connected commonly in multiple with each other, together with a battery and a dynamo driven switching commutator through which said battery is adapted to be connected in multiple with the aforesaid elements. Y

13. In combination a dynamo excited in duction coil, dynamo operated interrupter contacts, anda normally open shunt-circuit for the primary winding of said coil. all
