A suitable spring 9' fixed the electric motor. Similarly, an oscillatory rection, can be utilized for supplying current to this motor.

Briefly the operation is limited to bringing the arm .6 to bear on the stop 7 by any suitable means; the effect of this movement is to cause the gear wheels 2 and 3 to mesh and at the'saine time to supply current to the electric motor and once the engine is started the disengagement of the gear wheels 2-and 3 and the cutting oil of the current are effected automatically by the simple rocking movement of the arm 3 toward the stop 8.

It is obvious that instead of the gear wheels 2 and 3 friction rollers or any other connecting means may be employed.

Having now particularly, described .and

ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1- 1.. The combination with a rotary'part of an internal combustion engine, of an elecupon which ,said motor is ivotally mounted to swing into and out of operative position with respect to said rotary part of the en'-.

, gins, said support being so positioned that when the engine issta-rted'the motor will be automatically shifted toward its inopera- "rtiv'e position, apai'r of stops against one of .which a'part; of the motor abuts in either of its positions, and means tending to yield ,ingly retainthemotor in either of its'pos'i tions against the corresponding stop.

I. The combination with a rotary part of an internal combustion engine, of an elem tric starting motor-for the cnginc, a support upon which said motor, is pirotally mounted to swing intoand out of operative position with respect to said rotary part of the engine, said support being so positioned that u'henjthe engine is started the motor will be automatically shifted toward its inoperatitelposition, an arm projecting upwardly from the motor and mounted to swing therewith, a pair of stops against one of which said arm abuts in either position ofthe motor, and a spring actingon said arm and secured at a fixed point between said stops and below the axis of oscillation of said arin whereby said spring tends to yieldingly retain the'motor in either of its positipns.

5. The combination with a rotary part of an internal combustion engineaof an electric starting motor for the engine, a support.

a pair of stops against one of which said arm abuts in either position of themotor, a spring acting on said arm and secured at a fixed point between said stops andbelow the axis of oscillation of said arm whereby said spring tends to yieldingly retain the motor ineither ofits positions, an electric switch cont-rolled by themovement of said arm. and an electric circuit in which said motor is connected, said circuitbeinguclosed by said switch when the motor moves to its op.- erative position and-openedj'by said switch when the motor moves t'o-its' inoperative position. 4 In testimony whereof I afiix' my signature, inpr'esence oftwo witnesses.
